Distributed Transaction Processing Services in Oracle RAC 11.2
Hi,
Do we have to set the DTP parameter to TRUE for workload services that are going to be used for distributed transaction processing?
Something like this ...
srvctl modify service -d crm -s xa_01.service.us.oracle.com -x TRUE
Oracle 11.2 document is not very clear on this requirement. At one stage it says...
"Tightly coupled XA transactions no longer require the special type of singleton services (that is, Oracle Distributed Transaction Processing (DTP) services) to be deployed on Oracle RAC database. XA transactions are transparently supported on Oracle RAC databases with any type of services configuration."
But at the end of the same section...
"An external transaction manager, such as OraMTS, coordinates DTP/XA transactions. However, an internal Oracle transaction manager coordinates distributed SQL transactions. Both DTP/XA and distributed SQL transactions must use the DTP service in Oracle RAC."
So do we have to use DTP services with RAC or not?
Thanks,
-Sanjeev
