JCL Allocation Adjustments

You may need to adjust disk allocations to any JCL job stream.

For a new installation, the job CSMN5106 performs the initial CA Datacom/MSM disk allocations that are suitable for normal CA CSM usage. For an upgrade from a previous version, the job CSMUxx06 performs the initial CA Datacom/MSM disk allocations that are suitable for normal CA CSM usage.

xx

Indicates the version number that you are upgrading from.

Based upon your planned usage of CA CSM and your current DASD disk pool resources, you may need to adjust primary and secondary CA Datacom/MSM disk space to meet your site requirements. If you are performing an upgrade, verify that the new disk allocations are at least equal to the CA Datacom/MSM disk space currently in use.

To adjust disk space allocations when executing the MSMSetup.sh shell script, do one of the following:

• If in Review installation mode, enter Y (Yes) in response to the prompt if you want to preview JCL before automatic job submission.
• If in Manual installation mode, modify the runtimeHLQ.JCL data set as necessary before job submission.

You can adjust the disk allocation based on your expected usage of CA CSM Software Configuration Service (SCS) functions. The following disk allocations can be used for CA Datacom/MSM data area XML, the data set dbHLQ.XML4000, where dbHLQ is your high-level qualifier for the CA Datacom/MSM data sets:

• A minimum of one cylinder is sufficient if you are not using CA CSM functions to configure products.
• A minimum of 300 cylinders is sufficient if you are using a low volume of CA CSM functions to configure products.
• A minimum of 3,000 cylinders is sufficient if you are using an average to high volume of CA CSM functions to configure products.
