APAR status
Closed as program error.
Error description
<html>Starting a set of message flows that use the same complex ESQL files, one at a time, can cause the integration server running them to terminate. This only occurs if the message flows that are already started are under load when another stopped message flow using the same ESQL is started. Starting all message flows or stopping all flows at the same time does not cause this issue. When the issue occurs the terminated server will generate an abend file. </html>

Problem summary
**************************************************************** USERS AFFECTED: All users of deployable ESQL in IBM Integration Bus V9. Platforms affected: z/OS, MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A situation exists where certain ESQL statements (such as SELECT statements) are not thread safe during an initialisation process that occurs on the first message through a node that uses those ESQL statements. During startup, an integration server can crash if a large amount of deployable ESQL is going through this initialisation process whilst multiple message flows are starting, and those message flows are immediately processing messages when they start. <i>There are a number of resource name changes between WebSphere Message Broker and IBM Integration Bus Version 9.0. For details visit http://pic.dhe.ibm.com/infocenter/wmbhelp/v9r0m0/topic/com.ibm.e tools.mft.doc/bb23814_.htm</i>
Problem conclusion
ESQL initialisation code has been modified to remove a large amount of work that occurs during first message through. That work has been moved back into startup/deployment time when message flows are not yet started, and therefore the problem cannot occur. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 9.0.0.5 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
