Common Storage Area

When all CA MIM facilities are active, a minimum of 47 KB of system queue area (SQA) and 75 KB of extended system queue area (ESQA) are permanently allocated. Also, if you have a large peak of cross-system message traffic, CA MIC can temporarily use a variable amount of extended common storage area (ECSA).

Note: The total amount of storage used by all CA MIM components is difficult to estimate. It depends on system activity, the number of systems in a complex, and the total number of managed resources as defined using CA MIM parameters.

Note: For more information, see the appropriate Programming Guide.
