Error description
DB2IDAA defect pi43662 dpi43662 During migration from V11 CM mode to V11 ENFM, DSNTIJEN fails at ENFM0001 with DSNT376I timeout message. The holder of resource is the accelerator heartbeat monitor service task 033.ACCEKGE1. ************************************************************** Additional Symptoms and Keywords: IDAA IDAAV2R1/K IDAAV3R1/K IDAAV4R1/K DSNT376I MSGDSNT376I 033.ACCEKGnn 033 ACCEKGnn ACCEKG ABEND04E AB04E S004E 04E 04E-00E40601 00E40601 RC00E40601 DB2MIGV10/K DB2MIGV11/K DB2COEXIST/K DB2MIGV11/K
Local fix
use DB2 command -STOP ACCEL MODE(FORCE) SCOPE(GROUP) to terminate the accelerator
Problem summary
**************************************************************** * USERS AFFECTED: All DB2 for z/OS users who use IBM DB2 * * Analytics Accelerator (IDAA). * * Specifically those who are initiating an * * Enable New Function Mode (ENFM) migration * * from V10 or V11 Conversion Mode (CM) * * while accelerator services are started. * **************************************************************** * PROBLEM DESCRIPTION: Message DSNT376I is issued due to * * resources held by a DB2 internal, * * IDAA related, system task with a * * correlation ID of 033.ACCEKGnn. * **************************************************************** * RECOMMENDATION: * **************************************************************** A DB2 10 or 11 subsystem (stand-alone or a member of a data sharing group) is running in Conversion Mode (CM) with accelerator services started. The Enable New Function Mode job (migration job DSNTIJEN) is submitted to initiate the migration to Enable New Function Mode (ENFM). At job step ENFM0001, message DSNT376I is displayed indicating that the ENFM job has timed out waiting for a resource that is currently being held by one or more accelerator heartbeat monitor tasks. The correlation-id of an accelerator heartbeat monitor task is 033.ACCEKGnn, where nn can be any two characters. The ENFM job fails with abend S04E and reason code 00E40601.
Problem conclusion
DB2 10 and 11 have been changed to ensure that the resources held by an internal accelerator related service task are released in a timely manner. Any job or task needing access to those resources, e.g ENFM job, will therefore not be timed out waiting for those resources. Note: Data sharing users should be aware that, for a seamless migration, this change should be applied to all members that utilize accelerators.
