Snaplex configuration changes

Configure Snaplex nodes

Snaplex nodes are typically configured using the slpropz configuration file located in the $SL_ROOT/etc folder.

If you use the slpropz file as your Snaplex configuration, then you can expect the following:

  • After a Snaplex node is started with the slpropz configuration, subsequent configuration updates are applied automatically.

  • Changing the Snaplex properties in Admin Manager causes each Snaplex node to download the updated slpropz and do a rolling restart. If pipelines are still running, the node waits for the pipeline executions to complete before the Max. restart wait time expires.

  • Some configuration changes, such as an update to the logging properties, do not require a restart and are applied immediately.

  • Some configuration properties, like the Environment value, cannot be changed without doing manual updates for the slpropz files on the Snaplex nodes.

The Groundplex nodes must be set up to use a slpropz configuration file before changes to these properties take effect. If you change that affect the software configuration, but there are nodes in the Snaplex that are not set up to use a slpropz configuration file, a warning dialog appears with a listing of the unmanaged nodes.

Restart Groundplex nodes

To restart the Snaplex process on your Groundplex nodes, run the following commands, depending on your OS:

Linux: /opt/snaplogic/bin/jcc.sh restart

Windows: c:\opt\snaplogic\bin\jcc.bat restart.

Manage older Groundplex installations

If you have an older Snaplex installation with a configuration defined in the global.properties file, then the Environment value must match the jcc.environment value In the JCC global.properties file. To migrate your Snaplex configuration to the slpropz mechanism, see Migrating Older Snaplex Nodes.

You should always configure your Snaplex instances using the slpropz file because you do not have to edit the configuration files manually. Changes to the Snaplex done through Manager are applied automatically to all nodes in that Snaplex.

Temporary folder

The temporary folder stores unencrypted data. These temporary files are deleted when the Snap/Pipeline execution completes. You can update your Snaplex to point to a different temporary location in the Global properties table by entering the following:

jcc.jvm_options = -Djava.io.tmpdir=/new/tmp/folder

The following Snaps write to temporary files on your local disk:
