Errors in the Execution of the SDBUPD Program 

If errors occur when you execute the SDBUPD program, the program terminates with a message describing the cause of the error.

Frequent Causes of Errors

...

       1.      An unexpected error occurred when you executed SDBUPD.

       2.      You are attempting to use SDBUPD to switch to a software version that is lower than your current version (called a downgrade in the following). Examples of this situation:

¡        You selected the wrong software version by mistake.

¡        The upgrade of the database instance terminated with an error. You then tried to use SDBUPD to return to the original software version.

¡        The database instance upgrade was successful, however, you want to return to a lower software version for other reasons.

You cannot use SDBUPD to downgrade software. If you want to use SDBUPD, the new software must have at least a higher build number (Version Notation).

User Action

Proceed as follows in each case.

Case 1:

No database instances exist that refer to a higher software version.

Case 2:

Database instances exist that refer to a higher software version. You want to downgrade the software that is used exclusively by the database instance (Dependent Software).

Case 3:

Database instances exist that refer to a higher software version. You want to downgrade the software that is not used by the database instance, or whose version is not relevant for the database instance (Independent Software).
