 -8050: Migration error 

Explanation

An error has occurred while migrating a database instance with a database catalog stored in ASCII format (special database parameter _ = NO) to a UNICODE-enabled database instance (database parameter _UNICODE = YES). The cause of the error is logged in the file knldiag or knldiag.err.

User action

The action you need to take depends on what caused the error:

·        "RESTART REQUIRED BEFORE MIGRATION"
The database instance and its current software needs to have been in ONLINE mode at least once before the migration can start.

·        "UNHANDLED ENTRY TYPE: " + number of record type
The database catalog contains a record type that will not be migrated. All unhandled records are collected and an entry written for each one.
Contact Support.

·        "ERROR HANDLING TYPE " + number of record type
An error has occurred while processing a database catalog record of the type shown in the message. Migration is cancelled. The record is saved in the work directory under the name
MIGERRORREC.BIN. Please inform the SAP DB support team.

·        "ERROR WHEN RECREATING VIEW" + initial text of the defined view
An error has occurred while restoring a view table.
Depending which error has occurred, you must delete the relevant view table and, if necessary, regenerate it after the migration.

·        "MIGRATION FAILED FOR TRIGGER:" or "MIGRATION FAILED FOR DBPROC:"
Database procedures or triggers have been defined based on tables. However, the tables, columns, or users have since been renamed. These cannot be recreated. The system generates a list of all the database procedures and triggers that cannot be recreated. Migration is then cancelled.
The database procedures/triggers could no longer be used at the time of migration, so have to be deleted.

·        "CONSTRAINTTEXT IS TOO LONG:" + name of constraint
A constraint's definition text would exceed the maximum length if it were converted to UNICODE during migration. You must either delete or modify the constraint.

·        "CATALOG IS UNICODE ALREADY"
The database instance already appears to be UNICODE-enabled.

·        "_UNICODE has to be YES for migration"
The migration was started even though the database parameter _UNICODE was set as NO.
