Arguments
<dir> |
The directory to store temporary checkpoints. The default value is /tmp |
Use this option to indicate the directory to store temporary checkpoints. Checkpoints are migrated from -ckpoint-tmp-prefix to the directory specified in -ckpoint-prefix. The directory <dir> should be writable; otherwise the application will abort during startup with an error message. Temporary storage is not used if the option is not set.
Use this option for monitoring checkpoint activity. The trace is dumped into <file>. You should be able to write in <file>; otherwise the application will abort during startup with an error message. This is an optional feature.
