RP/TUX 8.0, TUX 8.1 - One-phase optimization is not performed (Doc ID 772638.1)

Last updated on JANUARY 19, 2018

Applies to:

Oracle Tuxedo / Tuxedo / 8.0, 8.1
Information in this document applies to any platform


With Tuxedo 7.1 and previous, when only one server in one group was involved in an update transaction this would result
in a one-phase optmization where ultimately the server itself would call xa_commit().

From Tuxedo 8.0 on however it seems that the commit processing is now systematically performed by the TMS.

This behavior seems to add unncecessary overhead in terms of processing and resource consumption, as well as defining
the TMS servers as bottlenecks in the architecture.
