Handling errors for global online change commands
When a global online change command results in an error, the action you perform depends on the state of the IMS™ systems in the IMSplex after the online change error has occurred.
The following table describes actions that you can perform when an online change command results in an error.
| IMSplex state after online change command error | User action to perform |
|---|---|
| One or more IMS systems in prepare complete state after a prepare failure. | Issue the TERMINATE OLC command. Correct the problem before reissuing the command. |
| All IMS systems in prepare complete state. | Issue the INIT OLC PHASE(COMMIT) or TERMINATE OLC command. |
| A mix of IMS systems in prepare complete and commit phase 1 complete state. | Correct the problem and try the commit again or issue the TERMINATE OLC command. |
| All IMS systems in commit phase 1 complete state before OLCSTAT data set updated. | Correct the problem and try the commit again or issue the TERMINATE OLC command. |
| All IMS systems in commit phase 1 complete state after OLCSTAT data set updated. | Correct the problem and try the commit again. The online change is committed and cannot be aborted. |
| Mix of IMS systems in commit phase 1 and commit phase 2 complete state. | Correct the problem and try the commit again. |
| All IMS systems in commit phase 2 complete state. | Correct the problem and try the commit again. |
| Mix of IMS systems in commit phase 2 complete state and not in online change state. | Correct the problem and try the commit again. |
