Two common reasons why a data group cannot be started are as follows:
-
The communications link between systems defined to the data group is not active. Use the procedure Verifying a communications link for system definitions.
-
The journaling environment for the data group has not been built. Verify that journaling environment defined in the journal definition exists. If necessary, use the appropriate procedure in the Assure MIMIX Administrator Reference book.
-
The journal receiver has been deleted from the system. You can use WRKJRNA to determine if the journal receiver exists on the source system.
