RECOVER
Performs maintenance on the ATCINFO file.
Syntax
RECOVER
Prerequisites
None.
Description
Use the RECOVER command to perform maintenance on the ATCINFO file.
Maintenance for the ATCINFO file 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 Turbo CONNECT
administrator is in the midst of an ATCUtil 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 command can be
used to compact the data in the ATCINFO file and return the free
space to the file system.
Example
In the following example, the ATCINFO file associated with the PartsDBE
DBEnvironment is recovered.
