LLAPRMLB Parameter

Specifies a partitioned data set that CA PMO uses when writing LLA refresh parameters. This parameter allows CA PMO to automatically conduct selective refreshes of LLA. If you specify the LLAPRMLB parameter, you also should specify a value for the REFDELAY parameter and the parameters LLA=AUTO and OPERMSG=NO.

CA PMO writes three members to data set name. The names of these members are: CSVLLA1P, CSVLLA2P, and CSVLLA3P, and they correspond to members with the same name in the library that you specified on the //IEFPARM DD statement in the LLA startup procedure. (For more information on the LLA startup procedure, see the step Set up Automatic LLA Refreshes in the installation chapter of the CA PMO Product guide.) Every 10 seconds, CA PMO checks an internal list of all LNKLST library and member updates. If the period specified on the REFDELAY parameter has elapsed for an updated member or library, CA PMO writes an LLA refresh parameter for the updated member or library to one of the CSVLLAxP members. Each CSVLLAxP member in data set name contains records for 60 updates, maximum. (There are multiple CSVLLAxP members to ensure that all updates are recorded.) LLA reads the parameters in data set name and performs the selective refreshes.

CA PMO overwrites the CSVLLAxP members that it creates without changing the position of these members in data set name. This eliminates the need to compress data set name. (If you handle LLA refreshes manually, frequent compresses probably would be necessary.)

Format

The LLAPRMLB parameter has the following syntax:

LLAPRMLB=data set name

The LLAPRMLB parameter requires the following value:

data set name

The name of the data set that CA PMO uses to write LLA refresh parameters for updated libraries and members. Do not specify the name of your //IEFPARM DD data set (typically SYS1.PARMLIB).

If CA PMO does not have write access to data set name during initialization, it issues a U100 abend. If CA PMO lacks write access while it is running, (for instance, if there is an I/O error to the data set) it refreshes the entire LLA instead of issuing selective refreshes, and it continues to refresh the entire LLA instead of performing selective refreshes. Data set name must be allocated such that LRECL has a value of 80 and BLKSIZE has a value of 4800. It needs less than 40 blocks.

Default: None

Note:

• Keep the following items in mind when using the LLAPRMLB parameter:
• Do not code any other parameters on the LLAPRMLB statement.
• You must specify a different LLAPRMLB data set for each system that runs CA PMO.
• Do not manually place the CSVLLAxP members into the LLAPRMLB library. Allow CA PMO to create and initialize these members.
