Control Statements

Give careful consideration when defining the complex-level and system-level configuration options using the following two sets of control statements:

• OPTIONS control statement defines complex-level options that affect all of the defined systems.
• DUMPOPTIONS control statement defines system-level options that only apply to one specific system.

Business Value:

Proper initial settings of OPTIONS and DUMPOPTIONS control statement parameters will reduce the time frame required for the implementation process. These control statements map your business requirements for the handling of SMF data at your installation to the available product features.

The OPTIONS control statement lets you control product features that affect all defined systems.

The DUMPOPTIONS control statement lets you control how CA SMF Director creates and maintains the SMF history files for a specific system.

Additional Considerations:

The specification on the OPTIONS statement becomes the default at the DUMPOPTIONS level unless overridden by a DUMPOPTIONS specification. Consider the control statement mapping requirement for all systems that are to be controlled by CA SMF Director before proceeding.

We recommend that you use the following options on the OPTIONS statement:

• AUTODEL automatically removes expired entries from the SCDS. This reduces the overhead of maintaining history file index entries with expired data.
• DYNAM ensures that CA SMF Director dynamically allocates history files when performing dump, extract, and print operations. This option is required for logstream dumping.

We recommend that you use the following options on the DUMPOPTIONS statement:

• COPIES(2) forces CA SMF Director to create a duplicate copy of the dumped data (history file). If the primary copy of the data is damaged for any reason, you can use the alternate (alternate history file).
• SCRATCH forces CA SMF Director to perform a nonspecific mount request for a scratch tape when a new tape volume is needed for a history file. This option is required for logstream dumping.
• Either RETPD/ARETPD (retention period) or EXPDT/AEXPDT (expiration date) is required for the AUTODEL feature and increases the SCDS data set integrity. The use of RETPD/ARETPD is preferred.
• CATLG catalogs the history file data set.
