Problem summary
**************************************************************** USERS AFFECTED: Users who use activity tracing may be affected by this problem Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: WebSphere MQ activity tracing code was incorrectly dereferencing a null pointer causing the FDC.
Problem conclusion
The code logic was changed so that it would first check whether the variable contained a null pointer before trying to dereference it. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.1 Platform Fix Pack 7.1.0.3 -------- -------------------- Windows 7.1.0.3 AIX 7.1.0.3 HP-UX (Itanium) 7.1.0.3 Solaris (SPARC) 7.1.0.3 Solaris (x86-64) 7.1.0.3 iSeries 7.1.0.3 Linux (x86) 7.1.0.3 Linux (x86-64) 7.1.0.3 Linux (zSeries) 7.1.0.3 Linux (Power) 7.1.0.3 Platform v7.5 -------- -------------------- Multiplatforms 7.5.0.1 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
