Boolean
false
Purpose
The OpenAllFilesOnDbOpen parameter, when set to true, causes all database files defined in the _control.dat database control file (including all online partitions associated with a partitioned database file) to be opened and the timestamps checked when the database is opened.
During the upgrade to a new JADE release, the database upgrade process overrides the OpenAllFilesOnDbOpen value if it is set to true.
Parameter is read when …
The database server node is initialized; for example, when you restart the database server.
Hints
Use this parameter if you want your file timestamps checked when the database is opened rather than when the files are referenced.
Setting this parameter to true may result in an increase in the time required to open the database, especially in systems that have many map files. If any file is missing, the database open fails.
File timestamp mismatches are recorded in the jommsgn.log file.
