This part of the documentation provides information you should be aware of before you install and use Event Replicator for Adabas LUW.
The installation procedure requires ca. 10 MB disk space in the temporary directory (TEMP).
The product space requirements are documented in the Event Replicator for Adabas LUW manual.
For Adabas Event Replication, Adabas 6.1 SP4 or higher is required.
For Adabas-to-Adabas Event Replication, Adabas 6.3 SP1 or higher is required.
Please refer to the document Release Notes for CONNX SQL Engine, section Supported Platforms, Availability of CONNX Product Features for information describing the platforms on which the various components can be installed.
Important:
The Event Replicator for Adabas (LUW) product installation
is now available in the Software Download Center (SDC) in Empower:
https://empower.softwareag.com
(login required). Please consult the file INSTALL.TXT contained in the download
file for further details on installation
issues.
Note:
The following applies only for Adabas LUW Adabas versions 6.3
and below.
Users of Adabas installing Event Replicator for Adabas LUW for the first time, should check their Adabas license for the following line:
<Rex>yes</Rex>
In addition users who wish to use the new native Adabas-to-Adabas replication feature should have the additional entry:
<A2AREP>yes</A2AREP>
Important:
If this line does not exist, you should apply for a new
Adabas license.
Before installing Event Replicator for Adabas LUW, all databases that will be used as replication sources must be shutdown / terminated.
For a complete list of new features available with this release please see the CONNX 13.0 SP1 Release Notes.
This covers the product issues known at the time of release:
If you want to undeploy a replication, both the source and target databases must be active. Otherwise, the status of the replication in the databases on restart will be incorrect.
The installation terminates with an error, when the environment variable CONNXREGISTRY is not defined; e.g. the 32-bit version of the CONNX registry is not used.
The CONNXREGISTRY environment variable is created during the installation of the SQL Gateway and is a prerequisite for the Event Replicator for Adabas LUW.
Do not use localhost as the server name for the Adabas Source or Target tables. In certain instances using localhost as the server name may cause you to lose all your source table records during an initial state.
When you choose a source replication index, do not use a descriptor with the null suppression attribute set.
Null values within a null-suppressed descriptor cannot be replicated; if a descriptor contains null values the replication engine will disable during deployment. If the descriptor with the null suppression attribute set does not contain any null values, the tables will replicate but we recommend using another unique descriptor for replication.
If you use a descriptor with the Null Suppression attribute set you will get a warning if the CDD was created using SQL Gateway 6.6.1 or later; if the CDD was created in a prior versions the warning message will not appear.
Do not replicate Unicode data from Adabas to DB2. The Replication tool does not currently support replicating Adabas Unicode data into a DB2 database.
Do not install the Event Replicator for Adabas LUW on an NFS share. Due to the NFS caching mechanism, replication cannot guarantee data consistency. When NFS data flows over the network, it adds an additional step in accessing the physical disk.
If Event Replicator for Adabas LUW does not initialize successfully, the Adabas database will continue to start, but no replication will be performed.
When the button is clicked, only the CONNX connections in the CDD are tested using the supplied logon credentials. The individual Event Replicator for Adabas LUW components are not tested.
