CA Service Catalog 17.1
CA Service Catalog 14.1
In order to follow the best practices for reporting, an offline reporting environment is created in order to replicate tables between the production and reporting environments. There are specific configurations for Microsoft SQL Server and Oracle, but the issue occurs when the replication is enabled while performing upgrading/customization tasks. Actually the replication works fine when records are added, updated or removed, but it does not work fine when installers start updating tables structure.
Make sure the replication is disabled when upgrading CA Service Catalog. Consider talking to your database administration in order to understand the best way to stop the replication when performing tasks where the tables structure is changed.
