Adding a new Engine on the target platform requires, in the case of Linux only parsing of the new Engine script once the platform's Engine Controller Daemon has also been configured. In our example the new Engine is named IMSTOORA.
The actions performed by an Engine are described by an Engine Script. In this example the script will specify only simple mapping of fields in a COBOL copybook layout to columns in a the target relational table. See the Engine Reference for all the options available through Engine Script commands and functions.
While not as simple as straight replication due to potentially different names for corresponding columns and fields the most important aspect of the script will be the DATASTORE specification for the source CDC records:
DATASTORE cdc://<host><:port>/<publisher_agent_alias>/<engine_agent_alias>| Keyword | Description |
|---|---|
| <host> |
Location of the Capture Controller Daemon. |
| <:port> |
Optional, required only if non-standard port is specified by the service parameter in the Controller Daemon configuration. |
| <publisher_agent_alias> |
Must match the alias specified in the Controller Daemon sqdagents.cfg file on that host. |
| <engine_agent_alias> |
Must match the alias provided in the "sqdconf add" command "-\-datastore" parameter when the Publisher Agent is configured to support the new target Engine. |
DATASTORE cdc://<host><:port>/imspub/IMSTOORA
