GOAL:
What is the LKT status in the wait column of PROMON -> User Control
GOAL:
What is the meaning of an LKT status/wait?
FACT(s) (Environment):
All Supported Operating Systems
FIX:
LKT status means that the connections are waiting to gain access to the lock table to change it (usually to add or remove an entry). Some other process has locked the lock table because it is changing it. Normally these operations are very fast and the waiting period very short (microseconds). If the process that is holding the LKT lock no longer exists, then these waiting processes will wait forever.
The Progress Watchdog is designed to detect and clean up after processes that have connections to the database but no longer exist. However, the Watchdog must follow the locking protocols during the cleanup and it is possible, though unlikely, that it can get stuck waiting for resources too.
Determine why these processes are no longer there. Has something killed them? Check the database .lg file and system log files for more information.
