2.6 Journal Issues
With RTR Version 3 software, the format and content of the transaction journal have changed. In general, if you upgrade or migrate to RTR Version 3 but continue to use the RTR Version 2 API and DECnet, you can use your existing application without change, However, if an RTR Version 2 application stored and used a transaction ID, the changed transaction ID format of RTR Version 3 can cause problems to that application. To correct such a problem, change the application.
