APAR status
Closed as program error.
Error description
In some scenarios - for example if a channel security exit is used - it is valid for a remote IBM MQ client earlier than version 8 to provide user credentials to the queue manager using an MQCSP flow. In this scenario, if the non default option PasswordProtection=warn is configured in the qm.ini file, an AMQ9297W warning message is generated in the queue manager error log as expected, but the connection is terminated. A failure data capture record (FDC) with probe ID RN107010 is generated by the amqrmppa process with the reason code rrcE_BAD_PARAMETER.
Local fix
Update the remote client library to a supported version of IBM MQ, or configure the channel to use SSL/TLS.
Problem summary
**************************************************************** USERS AFFECTED: Users of IBM MQ who have set PasswordProtection=warn in the queue manager configuration file (qm.ini) and are connecting an application using an MQ client older than version 8 which is supplying username and password credentials via an MQCSP structure. As the password protection capability is only applicable to cleartext connections, the issue is not seen for clients using an SSL/TLS connection to the queue manager. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A logic error without the PasswordProtection=warn logic branch meant that the connection was incorrectly terminated with a protocol error, instead of being allowed to continue running after the AMQ9297W warning message was issued.
Problem conclusion
The logic error has been corrected in this scenario, so that the connection is accepted by the queue manager after the AMQ9297W warning message is issued. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.3 LTS 9.3.0.20 v9.4 LTS 9.4.0.0 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 ---------------------------------------------------------------
