VDB Refresh fails with ORA-14694: Database Must Be in UPGRADE Mode to Begin MAX_STRING_SIZE Migration (KBA5254)

 

 

KBA

KBA#  5254

Issue

A VDB refresh operation will fail if the value of MAX_STRING_SIZE on the Source is changed from STANDARD to EXTENDED.

VDB parameters are taken at the time the virtual database is created. As the virtual database was created with MAX_STRING_SIZE unset, that means that implicitly it is STANDARD.

Once the database is upgraded to use MAX_STRING_SIZE = EXTENDED, the Refresh operation fails with the Oracle error because it is using MAX_STRING_SIZE set to STANDARD, as those are the config parameters of the virtual database.

Resolution

To resolve the issue VDB Refresh fails with ORA-14694: database must in UPGRADE mode to begin MAX_STRING_SIZE migration:

  1. Create a new Template, for example Extended.

  2. Add the following entry to this Template MAX_STRING_SIZE=EXTENDED.

  3. Delete the VDB. 

  4. Reprovision the VDB using the newly created Template.

 

Note

Note:

Once the first refresh with the template-EXTENDED is used, there is no need for the virtual database to have a template anymore. It will only be needed when refresh to a snapshot with MAX_STRING_SIZE=standard is needed.

Troubleshooting

The following errors will be observed in the Command Output portion of fault when the VDB operation fails:
