TE_CHECK_BES_KEYS_AVAIL@BESn—Monitor BES Key Index

Use TE_CHECK_BES_KEYS_AVAIL@BESn to monitor the number of unique BES key index values in use by this BES. Each BES address space is allocated a range of BES key index values. Once a given BES uses all of the BES key index values assigned in its range, it begins acquiring available BES key index values outside of its range.

Default Interval

Every 24 hours.

Exception Interval

Every hour.

Best Practice

There should always be BES key index values available for use by a given BES. The BES key index values map to specific encryption keys. CA 1, and CA TLMS and IBM DFSMSrmm Tape Management systems track the BES key index values in use. These tape management systems can communicate back to CA Tape Encryption the keys still in use so the older, unused keys may be deleted. BES key index values of deleted keys are then reclaimed for reuse.

Parameters Accepted

This check accepts one parameter, THRESHOLD(nn). The value specified in THRESHOLD(nn) is the percentage of used BES keys to trigger this alert.

Range: 0 to 99

Default: 80

Debug Support

Yes.

Verbose Support

Yes.

Message

BESH0071E BESn is running short of BES key index values.
