hello,
My oracle is running on 11.1.0.7.0 on RHEL5 64 bit linux, its Fast start failover.

my standby host had some issues and it wasn't available for sometime and LGWR started grabbing these locks. Standby came up after 2-3 hours but
its not releasing the locks.
I removed broker configuration added again.
changed DB to Asyn mode and put back in sync mode but still no luck

HOW TO GET THIS CLEARED ?
