DEPRECATION
IBM Informix and IBM Db2 for z/OS are currently supported as either query layers or enterprise geodatabases in ArcGIS Desktop 10.x, and as data sources for ArcMap-based services; these databases are not supported in ArcGIS Pro, nor as data sources for ArcGIS Pro-based services. With ArcGIS Enterprise 10.9.1 being the last release of ArcGIS Enterprise to support services published from ArcMap, this will also be the last release of ArcGIS Enterprise to support referenced services from IBM Informix and IBM Db2 for z/OS.
To prepare for this change, Esri recommends that customers migrate to a database supported in ArcGIS Pro and future versions of ArcGIS Enterprise. Review the following technical paper for steps on how to republish services from a supported database.
