Global Variable Database Warning Messages

So that you can closely monitor your global variable databases, CA OPS/MVS issues warning messages as the database becomes full. CA OPS/MVS provides parameters that enable you to control and monitor these database indicators closely.

Note: For descriptions of these parameters, see the Administration Guide.

CA OPS/MVS also issues warning messages each time database usage increases by 5 percent above the threshold (for instance, at 85 percent, 90 percent, and 95 percent of capacity), even between GLOBALWARNINTVAL intervals. The usage levels triggering the warning messages are not reset while CA OPS/MVS is active, unless you change the GLOBALWARNTHRESH parameter to a different value. In this case, the high-usage level is reset to the threshold value.

The warning message OPS4290O, which can apply to either the permanent global variable database or the temporary global variable database, contains the following information:

• Whether the warning is for the temporary or the permanent global variable database.
• Current percentage of the database that is full.
• Number of blocks currently in use.
• Total number of blocks in the database (GLOBALMAX or GLOBALTEMPMAX).
• Name of the program or rule that, once executed, caused the threshold to be met or exceeded. This program or rule can or cannot be responsible for filling the database.

Note: CA OPS/MVS checks for the threshold being exceeded only when a new global variable is allocated or an existing global variable is extended. Therefore, the interval between the messages can be greater than the defined interval.
