Hi, I have written a package in Development which will create a database user in test and production environments. The above package calling(using db link)one more procedure which is there in production and test environments. we are calling the package in front end tool. whenever we try to create a new user, we are getting the below error . ORA-02041: Client Database did not begin transaction ORA-02063: Preceding line from <DB link name> Note: When we checked, the user is creating successfully in Prod Environment and not in Test Environment. Our oracle Prod version is 10.2.0.4.0 and Dev Db version is 10.2.0.4.0 and Test Db version is 10.2.0.5.0. Does 10.2.0.5.0 has any strictness on remote calls? Please provide your valuable suggestions asap. Thank You.
