This task describes how to
maintain the ATCINFO file.
Getting Ready
Maintenance
for the ATCINFO file (DBEnvironment-nameCR) may be necessary in either of the following situations:
If a crash occurs while the ATCINFO file is being modified. This may be
the case
if a crash takes place when the IMAGE/SQL administrator
is in the midst of an IMAGE/SQL utility command that updates the ATCINFO file.
When this occurs, the RECOVER command can be used to reconstruct the
ATCINFO file.
If the ATCINFO file contains too much free space.
This may be the case if multiple
databases are attached and then some are detached from the DBEnvironment.
When this occurs, the RECOVER statment can be used to compact the data in
the ATCINFO file and return the free space to the file system.
Performing the Task
To recover the ATCINFO file associated with the MusicDBE DBEnvironment,
