## Number of Cached History Pages

Number of cached history pages (<number>) exceeds number of cached OMS pages (<number>)

### Explanation

This message can occur for liveCache instances only.

In the data cache, the number of history pages is higher than the number of OMS data pages.

### User Response

Search for old OMS versions and transactions that prevent the history pages from being deleted in the data cache.

Check whether the reports /SAPAPO/OM_REORG_DAILY and /SAPAPO/OM_DELETE_OLD_SIMSESS are being executed at regular intervals (see also Monitoring OMS Versions).
