-901: Log full 

Explanation:

The log devspace is full. The following reasons are possible:

  1. The log devspace is not backed up continuously. The database administration tool makes modifications which together with modifications of other transactions result in a log devspace overflow.
  2. The log devspace is backed up continuously, but the backups are not performed fast enough or there is a very long transaction whose modifications together with the modifications of transactions running in parallel result in a log devspace overflow. The database administration tool performs modifications.

The issued SQL statement fails.

User Action:

  1. Save the log.
  2. Save the log devspace using the database administration tool.

    Repeat the SQL statement.

  3. The database system saves the log devspace needed by the very long transaction in other database devspaces. The command can then be repeated.

Check whether this state occurs frequently, that is whether the log devspace is too small for the number of users and average transaction length. In this case you should enlarge the log devspace using the database administration tool.

You should also check whether there is an error in the application programming which results in the very long or endless transaction and correct this if necessary.
