IV31942: DELETE JOB ON A TABLE MDL.JSF_JS_INST_FORECAST CAUSES EWAS HANG
Closed as program error.
System: Linux dbsm0000 6 2 s390x Number of nodes in db2nodes.cfg is: 1 0 dbsm0000 0 The issue is, as noted above, that the application runs a delete job on a table called MDL.JSF_JS_INST_FORECAST. The application appears to hang on this delete job. We verified that we can optimize the TWS code in order to perform the delete forecast operation.
This apar is applicable only to TWS 8.6 FP1 release that introduced the feature to remove the zombie forecast instances during the startup. When a forecast plan is created a temporary preproduction plan is generated and it is removed when the forecast is completed. If during the creation of the forecast, the customer kill the eWAS, some zombie forecast instances remain in the preproduction tables of the forecast. The eWAS startup clean these tables but using a single transaction. This apar implements the mechanism to delete the zombie forecast instabces during the startup of the eWAS with a block mechanismt.
This apar will be fixed into 8.6.0-TIV-TWS-FP0002.
Run the following command: delete * from MDL.JSF_JS_INST_FORECAST
