Note: Partitioning on new installations is no longer supported and is no longer provided as a checkbox option from the Web Setup windows; that is, you cannot create new partitioning on a server. Although the partitioning checkbox has been removed, upgrading to 8.0(1) does not automatically remove partitioning on an existing system. The New Name (long version) is reserved for the first instance of that product name and in all headings. The New Name (short version) is used for subsequent instances of the product name. Note: This document uses the naming conventions provided in each GUI, which means that in some cases the old product name is in use. The fault tolerant architecture of the Unified ICM system ensures continuous operation in the event of hardware or software failures. Certain system administration tasks might not be necessary depending on the level of fault tolerance present in your Unified ICM system. The central database resides on the Central Controller and is used for persistent storage of data. The local database (awdb) is used for real-time reporting and storing configuration data and scripts. You should understand how these databases are used in the system. However, you might want to become familiar with the aspects of system usage that affect database storage capacity. Although most administration is taken care of automatically by the system, there are several optional administration features you should be aware of (especially if configuration uses a simplexed Central Controller). These include backing up the central database, performing manual integrity checks on the local database (awdb), and examining the Logger’s event log files. The system software provides several tools for reviewing event data in the system. The following chapters describe these topics in more detail. Allows you to manipulate the default service account creation process.http://www.vacumatic.com.au/documents/hotpoint-fridge-freezer-manuals.xml For Windows 2008 R2, the following applications can only be invoked by users who are members of an instance Setup group, and local Admin group members (which is the default behavior on Windows 2008 R2). Upon invocation, each application will display the User Account Control (UAC) dialog with the publisher displayed as “Cisco UCCE”. Afterwards, the user may either run the application or shut it down. If the publisher is displayed as anything other than “Cisco UCCE”, the user must not continue to run the application since it may be compromised. However, the active directory tools (User List Tool and Agent Explorer Tool) within Configuration Manager will fail if they try to access Active Directory. For all the tools to function properly, the Config user can right-click on the icon and click on “Run as Administrator”, and then provide the credentials of a Setup user. If the logon user is a Setup user, the Configuration Manager will work properly for all the tools in it. Lets you set up and maintain your environment. The configuration includes the hardware within the system, the services provided by the system, and the agents who provide them. CMS allows the Agent Re-skilling Web Tool and the CMS Node options access to the configuration. Central and Local Databases The Central Controller includes a database that stores the system configuration information and routing scripts. Unified ICM software’s UpdateAW background process automatically keeps the local database synchronized with the central database. An Administration Client, which does not have a local database, points to a local database (awdb) for its data. When you save a change to configuration data or scripts, the system software immediately applies that change to the central database. The UpdateAW process copies the change to all local databases. This prevents other users from changing the same script until you have saved your changes.https://www.becompta.be/emploi/electrolux-epic-6500-sr-manual When you edit a script, the Script Editor automatically acquires a script lock for you. The script lock applies to only one script. Optionally, you can obtain a master lock that prevents other users from making any changes to scripts or configuration data. The master lock is for backwards compatibility only. If a user holds the master lock, only that user can make changes to any scripts or configuration data. The Lock Admin dialog box appears, showing the status of all locks. Step 2 Select the lock by clicking on the Type column of the row describing the lock. Step 3 Select Release. Step 4 Select Close when done. Unified ICM’s fault tolerant mechanisms operate in the background and are not visible from within Unified ICM applications. However, it is still important that you have a general understanding of the fault tolerant architecture and the implications it has for system administration. In some cases, the level of fault tolerance in the Unified ICM system can affect which administration tasks you need to perform. For example, in duplexed database configurations many typical database administration tasks such as database backups become unnecessary because exact copies of the central database are kept on each side of the system on separate computers. This chapter provides an overview of Unified ICM fault tolerance with a special emphasis on the fault tolerance of the Central Controller and the central database. This ability is called fault tolerance. To ensure that the system software continues to operate in the case of a computer failure, all critical parts of the system can be physically duplicated. There can be two or more physical Network Interface Controllers (NICs), two physical Peripheral Gateways (PGs) at each call center, and two Central Controllers. The communication paths between critical components can also be duplicated. The critical components of the system software include the Central Controller (CallRouter and Logger), PGs, and NICs. When both sides of a component (that is, Side A and Side B) are available to the system, that component is said to be duplexed; when only one of the pair is available, the component is running by itself, if it is set up as duplexed. You might have some components in your Unified ICM system that are duplexed and others that are simplexed. For example, you might have a duplexed Central Controller (two CallRouters and two Loggers) and simplexed Peripheral Gateways (in lab environment only) at call center sites. It takes more than duplicate hardware to achieve fault tolerance. The Unified ICM system can quickly detect that a component has failed, bypass that component, and use its duplicate instead. The system software can also initiate diagnostics and service so that the failed component can be fixed or replaced and the system returned to duplexed operation. Approaches to Fault Tolerance The system software uses two approaches to fault tolerance: hot standby and synchronized execution. In the hot standby approach, one set of processes is called the primary, and the other is called the backup. In this model, the primary process performs the work at hand while the backup process is idle. In the event of a primary process failure, the backup process is activated and takes over. Peripheral Gateways optionally use the hot standby approach to fault tolerance. The system software uses synchronized execution in the Central Controller. In the synchronized execution approach, all critical processes (CallRouter and Logger) are duplicated on separate computers. There is no concept of primary or backup. Both process sets run in a synchronized fashion, processing duplicate input and producing duplicate output. Each synchronized system is an equal peer. Each set of peers is a synchronized process pair. In the event that one of the synchronized processes fails (for example, a CallRouter goes off-line), its peer continues to run. There is no loss of data and calls continue to be routed. The following figure shows how synchronized execution and hot standby are applied in the system software. Figure 1: Duplexed Unified ICME Fault Tolerance PGs and NICs use the hot standby approach to fault tolerance. Note that the duplexed NIC in the figure above is implemented on two separate computers. Each computer has active and idle connections to the sides of the Central Controller. NIC fault tolerance is described in more detail later in this chapter. The two paths connect the device (for example, a PG) to a Central Controller Agent process on each side of the Central Controller. The Central Controller Agent is a software process that manages communications between the Central Controller and nodes in the Unified ICM system. At any one time, one of the two communications paths is active and the other is idle. All communication traffic between the Central Controller and the device is sent on the active path. If the active path fails for any reason, the second path is activated and all traffic is switched to the newly active path. The previously active path becomes the idle path. The communication protocols use buffering and acknowledgments to ensure that no messages are lost during the path failure and switch-over. After a communication path failure, the device periodically attempts to re-establish communication along the failed path. Node Manager Each Unified ICM component (except the Administration Client) includes a Node Manager process. The Node Manager is in charge of restarting Intelligent Contact Management processes that have failed. For example, each Logger and each CallRouter has its own Node Manager. If a Logger and CallRouter are installed on the same machine, two separate Node Managers run on that machine. If Loggers for multiple customers run on a single machine, a separate Node Manager runs for each customer. When a failure occurs in a single-customer Unified ICM system, the Node Manager might shut down the machine to initiate a reboot. However, in a Cisco Unified Intelligent Contact Management Hosted environment when a Logger or CallRouter fails, components for other customers might still be active on the machine. In such a case, the Node Manager for a Cisco Unified Intelligent Contact Management Hosted component does not shut down and reboot the machine, and manual intervention is required to restore the failed component. If the Node Manager does initiate a reboot, the Node Manager itself restarts when the machine reboots. The Node Manager then starts the other processes for the component. To set up automatic restart for any component, access the Web Setup tool's Service Management page to set a component's service as Automatic rather than Manual. Central Controller The Central Controller includes the CallRouter and Logger. The CallRouter and Logger processes are typically on separate computers. However, in smaller call center configurations the CallRouter and Logger processes can be on the same computer. The Logger process is always on the same computer. Note: Beginning with Unified ICM 7.0(0), the Logger changed from a single process to two running processes—one process handling configuration data and the other handling historical data. This allows parallel processing of the two kinds of data and, thus, a more efficient Logger. However, these two processes are still part of a single Logger node; that is, the functionality of the Logger remains essentially unchanged. Therefore, throughout this manual, reference will generally continue to be made to the Logger, without distinguishing between the separate processes. However, you should be aware that the new split in the Logger does affect failure and failover behavior. For example, if the historical Logger on side A fails, the system fails over to the historical Logger on side B; however, the still functioning configuration Logger on side A continues to be used. The Central Controller processes are duplicated and run as synchronized process pairs. In synchronized execution, if one component fails its peer continues running and the system runs without interruption. The Database Manager is also duplicated, but technically it does not run synchronized. Since all modifications to the database come through the Logger, the databases automatically remain synchronized. Two Sides All components of the Central Controller, with their duplicates, form one logical duplexed system. The system can be divided into two sides, each of which contains one side of a component. Each side of the Central Controller has a Database Manager, Logger, CallRouter, Synchronizer, and an Agent. By convention, the two sides are referred to as Side A and Side B. All components, processes, and configuration objects within a side are collocated; that is, located on the same local area network (LAN). However, Side A might be geographically separated from Side B. The following figure shows the two sides of a duplexed Central Controller. Figure 2: Duplexed Central Controller During normal operation, the two sides run in parallel. For example, information about each incoming call is processed by both CallRouters. Both CallRouters, using the same call routing scripts and identical information about the call centers, determine the same destination for the call. A duplexed Central Controller can tolerate a single device or system failure (for example, the loss of one CallRouter) without losing functions. A double failure, while extremely rare, typically results in some loss of functions. An example of a double failure would be if both CallRouters in a duplexed system were to go off-line. However, LAN outages and IP router failures can also cause single failures. The following figure shows five possible Central Controller failure scenarios. If a single Logger (whether historical or configuration Logger) goes off-line, the system software runs without interruption. All call routing and reporting functions remain available. The CallRouters continue to operate as a synchronized pair. The remaining Logger runs simplexed. When the failed Logger returns to service, the Loggers return to synchronized execution. When a CallRouter on one side of the Central Controller fails, that entire side of the Central Controller is removed from service. This is because the CallRouter plays an integral part in forwarding historical data to the historical Logger on its side of the system. The on-line side of the Central Controller runs as a simplexed system. Call processing continues uninterrupted and reporting functions are still available. In this failure scenario, side B of the Central Controller is removed from service due to the CallRouter failure. Call routing continues uninterrupted with the remaining Side A CallRouter; however, data in both databases slowly becomes out of date. If it is the historical Loggers that failed, all reporting functions are lost until at least one of the historical Loggers returns. If it is the configuration Loggers that failed, you cannot make any configuration changes until at least one configuration Logger is operational. Such a double failure is extremely rare. The system software continues to function as a simplexed system until the failed side of the Central Controller returns to service. All functions remain, but the system is running simplexed (without protection against an additional failure). When the off-line side of the Central Controller returns, normal duplexed operation is restored. A double CallRouter failure would temporarily disrupt call routing and reporting functions. This type of failure is extremely rare (especially in geographically distributed Central Controller configurations). Geographic Distribution To provide maximum protection against disasters such as fires, floods, and earthquakes, the two sides of the Central Controller can be in separate locations—even in separate cities. The two Synchronizers communicate with each other via a private wide area network (WAN) to ensure that they remain synchronized. This WAN, called the private WAN, is used for no other purpose than to ensure synchronization between the sides of the Central Controller. All input for the CallRouter and any changes to the Logger must pass through the Synchronizers. Each time a Synchronizer receives input, it passes that input to its duplicate on the other side. The two Synchronizers cooperate to ensure that they are both sending the same input to the Central Controllers on both sides of the system. The following figure shows how the Synchronizers combine input messages and send the messages in the same order to each side of the Central Controller. Figure 4: Role of the Synchronizers Both CallRouters receive the same input and generate the same output. The Synchronizers ensure that both sides of the Central Controller return identical destinations for the same call and write identical data to the databases. The following figure further illustrates the Central Controller and its device connections. As shown in the above figure, only one communication path is active at a time. The other communication path is idle (indicated by a dotted line). The system software sends heartbeats (brief periodic messages) over the idle path to ensure that it can still be used in the event that the active path fails. Synchronization and State Transfer In synchronized execution, duplicated processes are always processing identical input and generating identical output. Once the failed process returns, it is immediately updated with the current state of Unified ICM processes running on its peer. In order to synchronize one peer with another after a failure, the system performs a state transfer. The state transfer facility allows a synchronized process (for example, a CallRouter) to copy the variables in its memory to its peer. The recovering system receives the variables from the currently executing system and is able to restart with a copy of the current state of Unified ICM processes. For example, as soon as a failure is detected on the Side A CallRouter, the system software only uses Side B. When the Side A CallRouter is restarted, the system software invokes a state transfer to immediately update the Central Controller Side A components with the current state of their counterparts on Side B. In order to better understand synchronization and state transfer, it might help to take a closer look at CallRouter and Logger recovery. CallRouter Recovery When a single CallRouter process fails for any reason, the system software continues to operate without any loss of functions by using the other side of the Central Controller. This ensures that devices such as PGs continue to receive CallRouter output through the active CallRouter on the other side of the system. As a consequence of the CallRouter failure, the entire side of the Central Controller is removed from service. The Logger associated with the failed CallRouter sees no further inputs (and will not until the failed CallRouter is restored to full operation). All components on the failed side of the Central Controller lose synchronization with the other side. The CallRouter and Logger must all be resynchronized before normal duplexed operation can resume. For a single-instance Unified ICM, the recovery process begins when the Node Manager notices the failure of a CallRouter process and automatically restarts it. Other processes are not impacted. In a Cisco Unified Intelligent Contact Management Hosted environment, if several Unified ICM instances are running on the same machine, the Node Manager cannot restart the machine. In such Cisco Unified Intelligent Contact Management Hosted environments, manual intervention is required to restart the failed CallRouter process. The restarted CallRouter immediately initiates a state transfer from its currently executing peer. Each CallRouter sends a message to its Logger. The Loggers then perform their own state transfer. When the state transfer is completed, all processes are now synchronized. The newly on-line Central Controller sends an in-service status to all local Agents. It then begins processing input messages. After the state transfer, both sides of the Central Controller see exactly the same sequence of input messages. At this point the Unified ICM system is returned to full duplexed operation. At this point, both CallRouters are in service, but only one Logger is available. For a single-customer Unified ICM, when the Node Manager detects that the Logger has gone off-line, it initiates a shutdown and reboot of the machine. In a Cisco Unified Intelligent Contact Management Hosted environment, the Node Manager does not restart the machine. In this case, manual intervention is needed to restart the failed Logger. The Logger’s Node Manager automatically restarts when the machine reboots. Next, the SQL Server service starts automatically as part of the reboot. SQL Server automatic recovery runs to ensure that the returning database is consistent and that all transactions committed before the failure are recorded on disk. Once automatic recovery is completed, the Logger can then go through the application synchronization and state transfer process. If configuration data in the on-line database has changed, the state transfer also updates the configuration data in the returning database. However, in most cases configuration data will not have changed during the failure. Once the two Loggers are returned to synchronized execution, the system software might need to recover historical data that was accumulated during the off-line period. In a double Logger failure (both Loggers are off-line), the CallRouter continues to route calls. This is possible, even if it is the configuration Loggers that have failed, because the CallRouter loads configuration data in its program memory at system initialization. In a double Logger failure scenario, all messages and data that the CallRouter sends to an off-line Logger are discarded until a Logger is completely recovered. Each time a CallRouter starts, it loads configuration data from the central database into its program memory. Once the configuration data is loaded, the CallRouter can begin to route calls (even when the central database is not available). Therefore, when a CallRouter fails and restarts, at least one configuration Logger and central database must be available so that the CallRouter can load the configuration data into memory. The system components gather historical data and pass it to the CallRouter, which then delivers it to the historical Logger and the central database. The ability of the CallRouter to deliver data to the historical Logger and the central database is not necessary for call routing. However, Unified ICM’s monitoring and reporting facilities require both real-time data and historical data from the central database. Database fault tolerance and data recovery, therefore, are extremely important to the reporting functions of Unified ICM software. Cisco Unified Intelligent Contact Management Database Recovery Database recovery is the process of bringing an off-line database up to the same state as an on-line database. In a database device failure (for example, in a disk failure), some manual intervention is required to restore duplexed operation and bring the off-line database up to date. The following scenarios describe what happens in a system failure, a disk failure, and a software failure. System Failure When a single Logger, CallRouter, or Database Manager fails (for example, due to a power outage), the associated central database will go off-line. The process of bringing the off-line database back to full synchronization is completely automatic. If the Logger machine reboots, SQL Server automatic recovery runs to ensure that the database is consistent and that all transactions committed before the failure are recorded on disk. Note: If the Logger machine does not reboot, SQL Server automatic recovery is not required. After SQL Server automatic recovery is completed, the off-line Logger synchronizes its state with the state of the on-line Logger. After the state transfer process takes place, both members of the Logger pair can execute as a synchronized process pair. During the time that one database is off-line, configuration data might have been added to the contents of the on-line database. If any configuration data changed while one database was off-line, the configuration changes are applied to the database as part of the configuration Logger’s state transfer process. This configuration update happens as part of the state transfer before synchronized execution begins. Any historical data that accumulated in the on-line database is recovered after synchronized execution begins. Rather than attempting to recover the historical data immediately, the system software first restores system fault tolerance (that is, duplexed database capability and synchronized execution). The system software recovers historical data from the on-line database using a special process called Recovery. In Recovery, the historical Logger communicates with its counterpart on the other side of the Central Controller and requests any historical data that was inserted during the off-line period. The counterpart delivers the data over the private network that connects both sides of a duplexed Central Controller. If a disk failure disables one side of the Central Controller database, the disk must be repaired or replaced. Note: Contact your Unified ICM support provider if a disk failure occurs. Step 1 Rebuild the database structure from scratch on the new disks. Step 2 Restore the configuration data, either from: a. A snapshot of the on-line database. b. The most recent backup tape. c. A backup tape taken from the on-line side of the Central Controller database. d. ICMDBA tool using a synchronization operation with the other side of the Logger. At the time of the state transfer, any missing configuration data will be restored. Historical data is restored by the Recovery process, which is run automatically each time the Node Manager process starts on the Logger, or by loading the data from a backup tape. Software Failure Cases of software failure that leave a Central Controller database unavailable are handled in the same way as a disk failure (if the failure cannot be repaired by existing software tools). Contact your Unified ICM support provider if such a failure occurs. Network Interface Controllers The NIC has four physical controllers on each side of the Central Controller. Each of these controllers can simultaneously handle calls from the signaling network. Typically, each physical NIC handles part of the total call routing load for the system software. The NIC processes are implemented as non-synchronized process pairs (one process on each side of the Central Controller). The NIC runs as a process on the CallRouter machine. As a non-synchronized process pair, the NICs operate without knowledge of each other.
