Error description
The CreateDate (PCF id MQCA_CREATION_DATE) within a Queue Statistics message has incorrect contents. It should be of the form 'yyyy-mm-ddbb', where the last two bytes 'b' are blanks, but it has the contents 'yyyy-mm-gggg' where 'gggg' is some non-blank data corresponding to the first 4 bytes of the CreateTime. Therefore the portion of the CreateDate that might be expected to hold the day of the month (dd) in fact holds the hour of the day. This will usually result in the dd value being wrong. See the example below: String (MQCFST) Parameter Id : 2004 (MQCA_CREATION_DATE) Value : "2016-10-21.5 " String (MQCFST) Parameter Id : 2004 (MQCA_CREATION_TIME) Value : "21.53.56" This problem was introduced as a side-effect in MQ 8.0.0.5 via APAR IT12103.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of MQ 8.0.0.5 who are using the Queue Statistics PCF messages and are relying on correct formats appearing for the CreateDate portion of the message. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: After the change in IT12103, the CreateDate (12 bytes long) was copied wrongly from a data area that was 8 bytes long, so was smaller than the 12 bytes needed. Therefore the resulting CreateDate in the PCF message contained the first 8 bytes of the true creation date, and the first 4 bytes of the creation time, which was held in the next portion of memory. No unsafe memory operations took place, but the resulting data was incorrect.
Problem conclusion
The MQ code has been corrected to ensure a 12 byte data area is used to hold the creation date before copying to the PCF message. This ensures the value copied to the PCF message will be valid. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.7 v9.0 CD 9.0.2 v9.0 LTS 9.0.0.1 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 ---------------------------------------------------------------
