Error message: "Was changed by another user" -
说明
The error "Was changed by another user" appears for some failed updates in the job service log, e.g.:
“[810092] …. was changed by another user.”
A similar message may also appear when making changes in the front end tools, such as Manager. -
原因
When the object layer of Identity Manager is loaded, the values of properties are stored in fields “OldValue”. If a property is changed, a field “NewValue” is populated.
When the object layer is updating the database, a SQL Update Statement is created, where the NewValue fields are used for the update values and the OldValue fields are used in the WHERE clause of the same statement. So if someone else changed a value in the database, the statement will not find a record to update with this where clause. -
解决办法
If no one changed the record something must have been happened (changed) with the “OldValue” in the object layer. The next step would be to enable SQL logging and to reproduce the error in order to find out which properties are causing problems.
For the error coming as part of the script turn on SQL logging for the job service. This is described in the "Additional Logging" section of the following Knowledge Base (KB) article:
How to Enable TRACE Logging
The KB above can also be used to log errors that appear in front-end tools such as Manager. Provide any relevant logs to Support for further analysis.
