Hello,
we recently upgraded to 11.2.0.1, and since then are seeing ocassional ORA-02051 and Tuxedo OTS_CAT:1001. The errors seem to be at random, about 1 in 5 invocations of one particular application service fails.
More details are in the following thread in the Tuxedo forum.
2270505
10:57:10.284 Database execution error: DalStatement::execute ( ORA-02051: another session or branch in same transaction failed or finalized
105710.wblvshwpap1!DrepApp.5048.1.0: gtrid x0 x4e2d3e9d x8de8691: OTS_CAT:1001: WARN: xa_end() failed in pre-prepare phase with error = 100
Anybody else encountered transaction problems on upgrade to 11.2.0.1?
Roger
