The Siebel Universal Queuing routing engine writes agent state and work-item state data to a table called DUStore. In the dual-server configuration, if the primary server fails for any reason, the backup server recovers the system state from the data in the DUStore table. In a single-server configuration, you can also recover the system state from this table.
NOTE: In order to restart Siebel Universal Queuing in a clean configuration (with no pending work items, no agents logged in, no rules loaded, and so on), the recovery data must be deleted from the DUStore table by a database administrator.
A database table creation script is available on the installation CD for all database platforms that Siebel eBusiness Applications support. The DUStore database table must be created by the database administrator. You can create a new database or use an existing database, such as the Siebel database, to contain this table.
For instructions for creating the DUStore table, see Creating the DUStore Recovery Table.
The appropriate database client software for the database that you will use must be installed before you install the Siebel Universal Queuing routing engine. The installer detects which database drivers are installed and only displays the database options that are available on the server.
The installer requires information to connect to the database. The following tables show the required input for each supported database. The required input differs slightly for each database. The account name and password are required in each case.
Table 4 provides information for installing on Microsoft SQL Server.
Table 5 provides information for installing on IBM DB2.
Table 6 provides information for installing on Oracle.
