Enabling a CDD for Adabas to Adabas Event Replication
Enabling a CDD for Adabas to Adabas Event Replication is the first step in getting data replicated. This includes:
Opening a CONNX Data Dictionary (CDD)
Entering connection information to connect to the source and target databases through CONNX
Selecting which files to replicate from a source database to a target database
Enable a CDD for Event Replication if:
This is the first time you are using Adabas Event Replicator for LUW.
This is the first time you are using this CDD for event replication.
You are using a different CDD than the one used during the last event replication session.
After you enable a CDD for Adabas to Adabas Event Replication, you will have a CDD with replications that are ready for deployment (which starts replicating data from source database to target database).
The Event Replication Controller is designed to use a single CDD. When designing a set of replications create one CDD that includes all the desired source tables and target databases.
CAUTION:
Replications from two separate CDDs cannot be deployed to the same Controller. If you attempt to do so, the replications from the second Data Dictionary will replace the replications from the first.
Two separate CDDs cannot replicate to the same targets from two different controllers. Adabas Event Replicator for LUW is designed to maintain data integrity from the source to the target; any target modifications from more than one controller will result in replication errors, disabling Adabas Event Replicator for LUW.
1. If you do not have a replication CDD created,
create one. 2. Start the Replication Administrator. If this is the first time the Replication Administrator is used, the Open the Data Dictionary window appears.
Note:
Only CONNX Data Dictionaries (CDD) that contain both the source and target (destination) data bases can be used for replication. Both the source and target database must be for Adabas version 6.3 SP1 or later.
3. If the Replication Administrator has been used previously, the Open Systems Event Replication window appears. Adabas Event Replicator for LUW will open the last opened CDD by default.
If this is the CDD you want, you do not need to re-enable Adabas Event Replicator for LUW for this CDD and you can stop here.
If this is not the CDD you want, click File -> Open CDD and browse to a CDD that contains the source tables for replication and the target database. Continue below.
4. In the Configure Servers window, type in your User Name and Password in CONNX Logon Credentials and click Test Connection. A confirmation window will let you know if the data is valid.
5. Enter the server name or IP address of the Replication Server in Name/Address and the server port number in Port.
Note:
The default port is 9200.
6. Click Done. The Add Tables window appears.
7. Select the source file number(s) you want to replicate.
Note:
The target file does not need to exist, but if a file with the same file number does exist on the target, the FDTs will be compared and if they are different, a warning will appear. The target file must have the same file number as the source, so if there is a conflict, it must be resolved prior to continuing.
8. Click OK. The main Adabas Event Replicator for LUW window appears.
