DBOPEN - Databank Open functionality
DBOPENis run in multi-user mode, the index pages of the databank are checked before databank access can proceed, but the bulk of the databank contents (contained in the data pages) is checked in the background, thus minimizing the delay.
The checking performed by
DBOPENis done by the background threads, see Number of Background Threads. Therefore, increasing the number of background threads will increase the efficiency of the checking.
DBOPENfunctionality should normally be run as soon as the database server has been started.
