By default, the software package will be contained in /opt/continuent/software/tungsten-replicator-7.1.4-10 Adjust the path in the examples accordingly if your environment differs.

The JavaScript file for your new filter(s) need copying to the following location:

/opt/continuent/software/tungsten-replicator-7.1.4-10/tungsten-replicator/samples/extensions/javascript

You need to create a template file which contains the location of the JavaScript file and the additional configuration properties with the appropriate default values.

Create a file called number2binary.tpl that contains the following:

replicator.filter.number2binary=com.continuent.tungsten.replicator.filter.JavaScriptFilter
replicator.filter.number2binary.script=${replicator.home.dir}/samples/extensions/javascript/number2binary.js
replicator.filter.number2binary.roundup=true
replicator.filter.number2binary.debug=false

This tpl file needs to be copied into the following directory:

/opt/continuent/software/tungsten-replicator-7.1.4-10/tungsten-replicator/samples/conf/filters/default

If your filter uses json files to load configuration data, this needs to be copied into the /opt/continuent/share directory and also included in the tpl file created in Step 2. An example is as follows:

replicator.filter.{FILTERNAME}.definitionsFile=/opt/continuent/share/{FILTERNAME}.json

Now that all the files are in place you can include the custom filter in your configuration.

Any properties set with a default value in the tpl file, only need including if you wish to overwrite the default value

The following examples show how you can now include this in your tpm configuration:

For ini installations add the following to your tungsten.ini

svc-extractor-filters={existing filter definitions},number2binary
property=replicator.filter.number2binary.roundup=false
property=replicator.filter.number2binary.debug=true

For staging installations

shell> cd {staging-dir}

shell> tools/tpm configure SERVICENAME 
{other-configuration-values-as-requires} \
--svc-extractor-filters={existing filter definitions},number2binary \
--property=replicator.filter.number2binary.roundup=false \
--property=replicator.filter.number2binary.debug=true

shell> tools/tpm install

In the above examples we used the svc-extractor-filters property for the extractor replicator. If you are applying your custom filters to your applier, then use svc-applier-filters instead

Your custom filters are now installed in a clean and easy to manage process allowing you to use tpm for all future update processes

If there is a problem with the JavaScript filter during restart, the replicator will be placed into the OFFLINE state and the reason for the error will be provided within the replicator trepsvc.log log.
