About AOM Named Subsystem Parameters
The Application Object Manager (AOM) can maintain several different values for a particular parameter using named subsystems. For background information on named subsystems and named subsystem parameters, see About Named Subsystem Parameters. For information on configuring AOM named subsystem parameters, see Configuring Siebel Enterprise Server Named Subsystem Parameters. See Table 20 for a list and description of named subsystems used by AOMs.

Table 21. Selection of Named Subsystem Parameters

|
|
DSConnectString |
GatewayDataSrc |
String |
Specifies the host name of the Siebel Gateway Name Server. The value $(GatewayAddress) for the parameter ConnectString of the GatewayDataSrc section of the AOM's configuration file is replaced at runtime with the value for the named subsystem parameter DSConnectString. An incorrect setting for DSConnectString results in Server Administration not being accessible from the standard Web client. |
DSConnectString |
ServerDataSrc |
String |
Specifies the database connection information. On SQL Server and DB2, this information is the ODBC Datasource Name; on Oracle (native) this information is the service name from tnsnames.ora. |
DSFileSystem |
ServerDataSrc |
String |
Set this parameter to *FSM* to allow the use of the File System Manager server component for standard Web clients. |
DSMaxCursorSize |
ServerDataSrc, GatewayDataSr, or DataMart |
Integer |
The configuration file parameter MaxCursorSize is set for the AOM component using the named subsystem parameter DSMaxCursorSize. The applicable subsystem used by the AOM corresponds to the component parameter OM - Data Source. This parameter is only valid with IBM DB2 UDB for OS/390 and z/OS. See Parameters for Individual Data Source Sections for further details on MaxCursorSize. |
DSPreFetchSize |
ServerDataSrc, GatewayDataSr, or DataMart |
Integer |
The configuration file parameter PreFetchSize is set for the AOM component using the named subsystem parameter DSPreFetchSize. This parameter is only valid with IBM DB2 UDB for OS/390 and z/OS. See Parameters for Individual Data Source Sections for further details on PreFetchSize. |
DSEnterpriseServer |
ServerDataSrc, GatewayDataSr |
String |
Specifies name of Siebel Enterprise Server used by various named subsystems. The value in the AOM's configuration file is replaced at runtime with the value set for the named subsystem. |
DSRequestServer |
ServerDataSrc |
String |
Specifies where asynchronous calls are redirected, for example when using Interactive Assignment. Set this value to the logical name of the Siebel Server, not the machine name. The default value is null. |
To configure Named Subsystems using the Siebel Server Manager command-line interface, see Named Subsystem Management Commands.
