Chitranjan,
Please let me understand what you want to do...
- Disable LogSync
- SnapSync
- Enable LogSync
Is that correct?
If so, what are you attempting to accomplish?
Before you continue down this path, please be aware that gathering of archived redo logfiles is absolutely required during SnapSync. So, turning off LogSync then performing SnapSync will cause an alternate mechanism for gathering archived redo log files to be used. That is, the SnapSync job itself will add additional RMAN commands to collect archivelogs.
It is better to just leave LogSync running through the SnapSync.
Are you trying to conserve storage on your virtualization engine?
Please let me know what you think?
Thanks!
