Some new functionality has been added to some of the Adabas utilities in order to support A2A replication. The following contains a short description of these functions; please refer to the Utilities documentation for further details.
ADABCK is used for the initial state processing of the A2A replication, i.e. copying an initial state of a replication to the target database. Some extensions have been implemented in ADABCK for A2A replication in order to prevent transactions getting lost when the replication is started and also to mark the target files as replication target files. These extensions are called by the Event Replicator administration and are, therefore, not directly visible to the users. For this reason these extensions are not documented in the Utilities section.
If a database is no longer intended to be a replication source for A2A replication, the function ADADBM REMOVE_REPLICATION removes the replication system files and the database is reverted back to a normal database that is not A2A replication-enabled.
The new function ADADBM REPLICATION_FILES defines the new system files required for the A2A replication. This function must be executed before you can start with A2A replication.
Target files for an A2A replication cannot be updated by normal Adabas users. The new function ADADBM RESET_REPLICATION must be executed if you want to use these files as normal files again.
The new function DISPLAY=REPLICATION gives you an overview of the currently-defined replications and their status.
