Tungsten Replicator

Install Vertica Applier

Before installing the applier, the following additions need adding to the extractor configuration. Apply the following parameter to the extractor configuration before installing the applier
Add the following to /etc/tungsten/tungsten.ini
```
[alpha]
...Existing Replicator Config...
enable-heterogeneous-service=true

shell> tpm update
```
Note
The above step is only applicable for standalone extractors. If you are configuring replications from an existing Tungsten Cluster (Cluster-Extractor), follow the steps outlined here to ensure the cluster is configured correctly: "Replicating Data Out of a Cluster"
The applier can now be configured.
Unpack the Tungsten Replicator distribution in staging directory:
```
shell> tar zxf tungsten-replicator-8.0.4-132.tar.gz
```
Change into the staging directory:
```
shell> cd tungsten-replicator-8.0.4-132
```
Locate the Vertica JDBC driver. This can be downloaded separately from the Vertica website. The driver will need to be copied into the Tungsten Replicator lib directory.
```
shell> cp vertica-jdbc-7.1.2-0.jar tungsten-replicator-8.0.4-132/tungsten-replicator/lib/
```
Create the /etc/tungsten/tungsten.ini file using the example below as a template. Once created to suit your needs, run tpm to perform the installation:

If you encounter problems during the installation, check the output of the /tmp/tungsten-configure.log file for more information about the root cause.

Once the service is configured and running, the service can be monitored as normal using the trepctl command. See "Management and Monitoring of Vertica Deployments" for more information.
