Problem summary
**************************************************************** USERS AFFECTED: MQ Appliance users Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A DNS resolution error was incorrectly reported in the MQ Appliance error report when a host-alias existed with an alternate IP version (IPv4 vs. IPv6).
Problem conclusion
The code is modified such that the IPv6 DNS lookup of an IPv4 host-alias does not result in an external DNS lookup. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.7 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 ---------------------------------------------------------------
