Known issues (IBM Db2)

DLPXECO-12057

In the IBM Db2 v4.9.0 connector, the default value of the skipDb2VersionCheck parameter was changed to True. This means the connector no longer performs validation of the Db2 server version—covering major, minor, fixpack, and modpack levels—during initialization.

As a result, the connector may attempt to provision VDBs on unsupported Db2 versions, which may fail due to compatibility issues.

If there are environments with more than one Db2 versions installed, it is recommended to explicitly set skipDb2VersionCheck=False in the db2_plugin.conf to make sure there are no unforeseen errors due to version compatibility issues.

DB2-2231

During upgrade from 6.0.x to 7.0, 8.0, ….21.0 , Delphix engine destroys the plugin’s scratch path where all the plugin logs, configuration files are present. During the environment refresh, these paths and files are regenerated. However, any edits done in db2_plugin.conf will not be persisted

Before upgrading the engine, the user will have to make a copy of the db2_plugin.conf file to keep the changes intact.
