Release 10.1A: OpenEdge Data Management:
Database Administration

> ## JTA processing impact

> Enabling the database as a JTA resource manager alters database processing in the following ways:

> - Crash recovery — Crash recovery processing executes every time a database is started, whether in single-user or multi-user mode. A JTA enabled database must perform crash recovery in multi-user mode. Attempting to perform crash recovery in single user mode will result in an error if any JTA transactions exist in at startup in a prepared state.

> - Roll forward recovery — After-image files written by a JTA-enabled database, must be applied to a JTA-enabled database. In addition, the `endtime` and `endtrans` options for ROLL FORWARD are not allowed.

> - Fathom Replication — A JTA-enabled database cannot be replicated with Fathom Replication.

> - Before-image processing — Long running JTA transactions prevent reuse of before-image clusters.
