Establishing Session Options

Established at Signon

CA IDMS establishes options for your runtime session when you signon on to a DC/UCF system or when CA IDMS/DB issues its first database request from a batch application (in local mode or under the central version) or external teleprocessing monitor. The manner in which CA IDMS implements the options and how they affect your session depends on the runtime environment.

Specifying a Default Database or Dictionary

CA IDMS/DB provides several ways to specify a session default dictionary or database. The methods available depend on the runtime environment.

Online Processing

To specify a session default in an online environment, you can:

• Specify DICTNAME/DICTNODE or DBNAME/DBNODE attributes in a system or user profile
• Issue a DCUF command
• Issue a compiler SIGNON or CONNECT statement naming the dictionary and/or database from within an online CA IDMS/DB compiler or tool (this will update the default dictionary for the runtime session)

Batch Processing

To specify a session default dictionary for a batch central version or external teleprocessing monitor application, you can use:

• An IDMSOPTI module (for non-SQL applications only)
• A SYSCTL file
• A SYSIDMS parameter file

Note: For more information about how CA IDMS/DB determines which database or dictionary to access when provided with information by the program, IDMSOPTI module, SYSCTL file, and SYSIDMS file, see the CA IDMS System Operations Guide.

Local Mode Processing

To specify a session default for local mode, you can use:

• An IDMSOPTI module (for non-SQL applications only)
• A SYSIDMS parameter file
