Error description
DB Sensor processing was halted when S000A abend occur. The abend occurred because of two asynchronous processing requests against the data set CSS.SWG.IMS.DDXSV01.DBXSV01. Both requests are a VERIFY request, which validates the high used RBA. It appears that one has started and moving along and the second request comes in and is doing the same thing. When the second request gets control, it ends up waiting on the first request.

Problem summary
**************************************************************** * USERS AFFECTED: IBM IMS Database Reorganization Expert for * * z/OS V4.1(FMID=H25N410) users who run * * Smart Reorg utility. * * And, IBM IMS Database Solution Pack for * * V1.2(FMID=HAHP120) or V2.1(FMID=HAHP210) * * users who run FF Stand-alone Database Sensor * * (DB Sensor). * **************************************************************** * PROBLEM DESCRIPTION: When DB Sensor processes a VSAM file, * * DB Sensor scan processing is caused to * * the wait state after System ABEND * * 00A-0004. * **************************************************************** * RECOMMENDATION: Apply the maintenance for this APAR. * **************************************************************** DB Sensor enters the wait state and cannot complete the database scan processing under the following conditions: -DB Sensor runs as FF Stand-alone database Sensor or it runs under IMS Database Reorganization Expert -The processing database data set is VSAM ESDS or KSDS. Before DB Sensor is placed into the wait state, ABEND 00A (System Code=00A reason code=0004) occurs in the VSAM component. The reason of ABEND 00A is two asynchronous DB Sensor processing issue the same VERIFY request against the same VSAM data set. The first request has started and is moving along, the second request comes in and is doing the same thing, and the ABEND 00A occurs. When the second request gets control, it ends up waiting on the first request.
Problem conclusion
The following module has been modified to avoid the multiple VERIFY macro to one VSAM data set. BBESSCAN
