Error description
After setting the environment variables MQCHLLIB and MQCHLTAB to make use of the CCDT, the .NET client application fails to connect to the queue manager reporting AMQ9518 . The following error is written to the error log: Process(1234.1) User(IBMuser) Program(test.exe) Host(IBMSupportbox)Installation(Installation`) VRMF(7.5.0.2) AMQ9518: File '#:\###\AMQCLCHL.TAB' not found. EXPLANATION: The program requires that the file '#:\###\AMQCLCHL.TAB' is present and available. ACTION: This may be caused by invalid values for the optional environment variables MQCHLLIB, MQCHLTAB or MQDATA. If these variables are valid or not set then record the name of the file tell the systems administrator who must ensure that file '#:\###\AMQCLCHL.TAB' is available to the program.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All MQ client application that connects to the queue manager using CCDT. Platforms affected: Windows **************************************************************** PROBLEM DESCRIPTION: If first connection of a client application does not use the client channel definition table (CCDT) file and if the second connection made by the same application tries to use CCDT to establish connection with the queue manager then the client code looks for the CCDT file only in the default path. It does not attempt to pick the value set in the environment variable MQCHLLIB and hence the connection fails if the CCDT file is not in the default path.
Problem conclusion
MQ code has been modified to retrieve the CCDT information from the environment variable. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.0 7.0.1.13 v7.1 7.1.0.6 v7.5 7.5.0.5 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
