Number of cached history pages (<number>) exceeds number of cached OMS pages (<number>)
This message can occur for SAP liveCache technology only.
In the data cache, the number of history pages is higher than the number of OMS data pages.
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 Database Administration in CCMS, Monitoring OMS Versions).
