Migration of Galaxy to System Platform 2023 Never Completes

When migrating a Galaxy from an older version to System Platform 2023, the process hangs without any errors or warning and never completes.

By default, the migration process handles 500 templates at the same time from the original Galaxy. If there are more than 500 templates, this may exceed the 3.5 GB that aaGR process can handle, causing a crash as we see in the Log Viewer.

This tech note provides the steps to change the default MaxTemplateCacheSize from 500 templates to 10 to make sure the 3.5 GB limit is not violated.

Adding Auto Reconnect Functionality to Device Integration Objects

When a Device Integration object gets disconnected from its data source (e.g. an AVEVA OI Server), it must be manually triggered to reconnect when the source becomes available again.  This tech note will instruct you on how to set up an auto reconnect feature and add additional diagnostic information that will indicate the number of disconnects the object has experienced since it last went on scan.
