VPE Sync Usage Notes

This section contains information about various topics that can affect the way you use VPE Synchronization in your day-to-day operations.

Important Access Considerations

There are several important aspects of user access that you must consider when planning how to create and run VPE Synchronization subscription jobs.

  1. The VPE Synchronization job will run under the account and privileges of the last person to create or modify the sync job. In other words, the person who logs into VPE Synchronization and creates or edits a job is the person under whose account the job will run.

  2. To create/modify VPE Sync jobs, the logged-in user must belong to the group defined by " "vpe.sync.admin.group= " in the Installation Wizard at installation time. This typically means that the logged-in user must have VPE Admin privileges. Image

Access Control permissions: If your deployment has implemented aPriori Access Control, you must also ensure that your logged-in user has the correct permissions to access ALL the VPEs that will be involved in the synchronization process.  If not, the job may fail or may return incomplete results. For general information about Access Control, see the "Access Control" section of the aPriori System Administration Guide.

Synchronization and Overlays

The basic rule for VPE Synchronization is that it returns VPEs only if they are more recent than the ones in the subscriber deployment, or if they do not already exist in the subscriber deployment.

In the context of overlay VPE bundles, the subscription server will request the overlay bundle from the source if the local copy of ANY VPE in this bundle is outdated. Then the subscriber server will update only those local VPEs in the bundle which are outdated.

Troubleshooting

As with most Enterprise Platform product modules, troubleshooting information can be found in the Tomcat logs in apriori-platform\Tomcat\logs. However, note that for some issues, the logs for the source installation will provide more useful information than the logs for the subscriber installation.
