Descriptions and Formulas

KRN_Alias_Remain_Critical

The catalog connector record is running out of space. Few new aliases can be added to user catalog connector record. This is estimated based on the average length of the aliases currently defined and the remaining space in the user catalog connector record.Define or identify a new catalog that can be used for the creation of future aliases, or use the ITACM MERGECAT command to split the number of high level qualifiers into two or more catalogs. The default configuration has the following SQL syntax:

*IF *VALUE KRN_ALIAS_SPACE.ALIASROOM *LT 100

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.

KRN_Cat_4GB_Limit_Critical

The catalog size is close to the 4 gigabyte limit There is limited space remaining in the catalog for entries to be defined. If multiple high level qualifiers are defined to the catalog, they will need to be split into two or more catalogs. The MERGECAT command can be used to accomplish this.

Otherwise, consider implementing multi-level aliases for the one HLQ so that the entries in the catalog can be split into two or more catalogs. The default configuration has the following SQL syntax:

*IF *VALUE KRN_CATALOG_DATASET_ATTRIBUTES.PCT4GBLIM *GT 90

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.

KRN_Cat_Backup_Critical

The last backup job for a catalog had a return code >= 8. A return code > 8 indicates that the backup for this catalog failed, so the catalog cannot be restored properly from this backup. Review the output from the backup job and the documentation to try to determine the cause of the problem. After addressing the problem, rerun the backup. The default configuration has the following SQL syntax:

*IF *VALUE KRN_LAST_CATALOG_BACKUP.LBKPRC *GE 8

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.

KRN_Cat_Backup_Warning

The last backup job for a catalog had a non-zero return code < 8 Review the output from the backup job and the documentation to try to determine the cause of the problem. After addressing the problem, rerun the backup. The default configuration has the following SQL syntax:

*IF ( ( *VALUE KRN_LAST_CATALOG_BACKUP.LBKPRC *GT 0 ) *AND ( *VALUE KRN_LAST_CATALOG_BACKUP.LBKPRC *LT 8 ) )

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.

KRN_Cat_Extents_Critical

The catalog is close to running out of extents. The maximum number of extents for a BCS is 123 at which point applications may fail when they attempt to catalog a data set. In order to avoid reaching this maximum, a reorganization of the BCS is needed. The BCS can be reorganized using Tivoli Advanced Catalog Management using either the REORG command, or by doing a BACKUP followed by a RESTORE. The default configuration has the following SQL syntax:

*IF *VALUE KRN_CATALOG_DATASET_ATTRIBUTES.EXTENTS *GT 100

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.

KRN_Cat_Hit_Pct_Warning

The Low Hit% threshold has been reached. A Hit% < 20% probably means that the overhead of managing the cache costs more than just doing the I/O to DASD. For CDSC caching, consider increasing the amount of virtual storage allowed for catalog caching, or reverting to ISC caching, or not caching at all. Newly opened catalogs and master catalogs can have low hit%. The default configuration has the following SQL syntax:

*IF *VALUE KRN_CACHE_PERFORMANCE.CCHPCTHIT *LT 20 *AND *VALUE KRN_CACHE_PERFORMANCE.CATTYPE *NE Master *AND *VALUE KRN_CACHE_PERFORMANCE.CCHSEARCH *GT 100

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.

KRN_Non_Zero_Job_Submission_RC

A job submission failed with a non-zero return code. A requested job has failed to be submitted, please check the return code and reason code for more information. The default configuration has the following SQL syntax:

*IF *VALUE KRN_EVENT_INFORMATION.RETCODE *GT 0

This situation evaluates data as it becomes available.

This situation is automatically distributed to instances of this agent.

KRN_Vol_Frag_Idx_Critical

The volume fragmentation index exceeds the critical threshold. The volume should be defragged to prevent dataset allocation failures on the catalog(s) on this volume. The default configuration has the following SQL syntax:

*IF *VALUE KRN_CATALOG_VOLUME_SUMMARY.FRAGIDX *GE 850

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.

KRN_Vol_Pct_Full_Critical

A volume containing a catalog is getting full. To allow the catalog(s) on this volume to accept new entries, either migrage some datasets to another volume, or release space from dataset that may be over allocated. The default configuration has the following SQL syntax:

*IF *VALUE KRN_CATALOG_VOLUME_SUMMARY.PCTFULL *GT 95

This situation is evaluated every 1 minute.

This situation is automatically distributed to instances of this agent.
