Use the check command to scan for corruptions in the calendar database, including calendar properties (calprops) and events and todos (tasks). If the check command finds an inconsistency that cannot be resolved, it reports the situation in its output.
The check command does not check for corruption in the alarm or group scheduling engine (GSE) databases.
To check for database corruption:
Log in as a user who has administration rights to the system where Calendar Server is installed.
Calendar Server can be either running or stopped; however, if possible, stop Calendar Server.
Make a copy of your calendar database, if you haven’t already done so. Copy only the database (.db) files. You don’t need to copy any share (__db.*) or log (log.*) files.
Change to the cal_svr_base/SUNWics5/cal/sbin directory. For example, on Solaris Operating Systems, enter:
Run the check command on the copy of your calendar database:
./csdb check dbdir \> /tmp/check.out 2\>&1
If you don’t specify dbdir, check uses the database in the current directory.
The check command can generate a lot of information, so consider redirecting all output, including stdout and stderr, to a file (as shown in the example).
When check has finished, review the output file.
If your database is corrupted, you can choose to replace it with your hot backup copy. Alternately, you can choose to try to rebuild the corrupted one by running the rebuild command.
