APAR status
-
Closed as program error.
Error description
-
Allow suppression of protocol error caused by v5 Java/JMS clients
Local fix
-
Update the affected Java applications to use a supported level of the MQ classes for Java or MQ classes for JMS
Problem summary
-
**************************************************************** USERS AFFECTED: Users of current MQ maintenance levels who are using unsupported MQ 5.2 or 5.3 Java/JMS client levels Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Additional data length validation checks were added under APAR IT42945. Some MQ 5.2 and 5.3 Java clients, which are no longer in support, contain a defect which send an invalidly-sized transmission to the queue manager when attempting to establish. The incorrect size of this transmission is not harmful to the queue manager, but is correctly detected as malformed by the new validation checks, resulting in the queue manager terminating the connection attempt with a protocol error.
Problem conclusion
-
This APAR adds an additional tuning parameter that can be provided by IBM support in the event that the use of unsupported Java/JMS clients cannot be immediately remediated. The tuning parameter suppresses the relevant data length check for transmissions that are consistent with the invalid transmission sent by the defective 5.2 and 5.3 Java clients. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 LTS 9.0.0.23 v9.1 LTS 9.1.0.20 v9.2 LTS 9.2.0.25 v9.3 LTS 9.3.0.15 v9.x CD 9.3.5 The latest available maintenance can be obtained from 'IBM MQ Recommended Fixes' https://www.ibm.com/support/pages/recommended-fixes-ibm-mq If the maintenance level is not yet available information on its planned availability can be found in 'IBM MQ Planned Maintenance Release Dates' https://ibm.biz/mqplannedmaintenance ---------------------------------------------------------------
