The default startup mode for qdb is with both shared caching and exclusive modes enabled:
- If you want to disable shared caching, you must use the -D command-line
option.
- For shared caching, qdb reserves exclusive write privileges to the database.
To allow other applications to use the database files, use the -A
option.
Note:
qdb will exit immediately if it is started with shared cache disabled and exclusive mode enabled. For example:
# qdb -c /db/qdb.cfg -v -D -Otempstore=/fs/tmpfs -Rset
qdb: Exclusive locking mode requires that shared cache be
enabled
