Hi all,
Can anybody tell me what are the specific reasons for mutex error in version
7 (Parralel extender) ? Also tell me what are the solutions to solve the
mutex problem ??

Mutex Error..
Don't know about PX, in Server it generally involves Row Buffering (I
believe) and needing to set the Timeout value either higher or to zero.
Suggest you go to http://www.dsxchange.com, this list is archived there and
there are also very active DataStage forums for Server and PX. Do a search
for 'mutex', this issue has been discussed many times before.

Mutex Error..
Mutex errors don't occur in DataStage.
Rather, they occur in the operating system. A "mutex lock" is one way in which a "wait" mechanism is implemented. Usually, they wait for a certain number of CPU cycles, then take a timeout error. As CPUs have become faster, the default wait is not long enough; the amount of time needed for those cycles to complete gets shorter. To quote one engineer, the CPU is just too fast for its own good!
All that said, the topic of DataStage usage of mutex locks has been canvassed on this forum in the past, a search should reveal causes and workarounds.
