The CacheUseExpiredIfNecessary workflow system property defines how the Content Platform Engine server, upon receiving an on-demand request to access a user or group environment record, refreshes an out-of-date memory environment record.
If you set the CacheUseExpiredIfNecessary property to false, the Content Platform Engine database is updated according to the interval specified by the CachedEntryTimeout property. If a cached database record is older than the value that is specified by the CachedEntryTimeout property, the Content Platform Engine server updates the cached record from the Content Platform Engine database. Otherwise, if CacheUseExpiredIfNecessary is set to true, the Content Platform Engine server does not attempt to update an out-of-date cached database record. The default value for CacheUseExpiredIfNecessary is true.
This property is available only in IBM® FileNet® P8 Version 5.2.1.0-P8CPE-IF002 or later.
