My boss asked me to upgrade one of the development databases from 13.5 --> 14.2. One thing that we've noticed right away is that XA transactions (2-phase commit) are much slower on 14.2 than on 13.5. Were there any significant changes to the XA protocol in the version 14? Did anybody else encountered this problem?
When I say "XA transactions are much slower", I mean that commit
and/or rollback take much longer. The SQL execution takes the same
and the plans are identical to the 13.5 version. The application
code is the same, using IBM WebSphere 9.0.4.
