Unable to trigger DataStage jobs from SAP

Question>
We are unable to trigger any DataStage jobs from SAP. When I try to invoke a DataStage job from SAP infopackage in a BW Load - PULL operation, I see this message in the log:

> cat RFCServer.2010_02_26.log
2 I: BW Open Hub Extract: Data ready for BW initiated job. InfoSpoke Request ID 306696. Fri Feb 26 09:45:00 2010
4 I: BW Load: Notifying push job request REQU_4GZ0F9G5SIAEE283M04XSUM9G is ready at Fri Feb 26 11:08:55 2010

But the DataStage job is not triggered. The info package keeps waiting forever to receive data but the DataStage job that provides data never gets triggered.

Running jobReset to cleanup the temporary files:
Open a command prompt window to the DS Server and:
1. source dsenv:
cd /Server/DSEngine
. ./dsenv
2. run the job reset utility
cd $DSSAPHOME/DSBWbin
./jobReset
where = MASTER | MASTERTEXT | TRANSACTION | MASTERHIERARCHY
for example:
cd /hpithome/IBM/InformationServer/Server/DSBWbin
./jobReset SAPBW8 PACK09 IS1 MASTER bwload
You should get a confirmation message: "jobReset - Successful"
