The default startup mode for qdb is with both shared caching and exclusive mode enabled.
You can change this as follows:
- To disable shared caching, use the -D command-line option.
- When shared caching is enabled, qdb reserves exclusive privileges for writing to the database.
To allow other applications to use the database files, use the -A option.
Note:
The
qdb utility exits immediately if it is started with shared cache disabled but exclusive mode enabled.
For example:
# qdb -v -D -otempstore=/fs/tmpfs -Rset
qdb: Exclusive locking mode requires that shared cache
be enabled
