we hit from time to time the following issue:
- some rows from a table are locked

  • there is no blocking session information and the session, which tries to acquire lock has blocking_session_status set to NO HOLDER

The rows are locked by Tuxedo transaction. We suppose we hit the situation, when Tuxedo's TRAN_TIME is longer than distributed_lock_timeout and it seems setting those values to order TRAN_TIME<distributed_lock_timeout will solve this issue.

Question is how/where to search for more information about the "thing" holding lock and if it is possible to release such lock for example by forcing a local rollback?
