When restoring an XML backup, (possibly during migrations to Oracle from other DBMS) the import can fail with an ORA-01461 SQL error:
In fieldtype-oracle10g.xml, "very-long" is defined as a VARCHAR(4000) which often can be insufficient to store the desired information. Any entity field that is defined as such in the entitymodel.xml can potentially contain large enough data is susceptible to the problem.
There are two possible solutions:
- Modify $JIRA-Installation-Directory\atlassian-jira\WEB-INF\classes\entitydefs\
WEB-INF/classes/entitydefs/fieldtype-oracle10g.xml to define very-long as a CLOB.
- Increase the size of the particular field in $JIRA-Installation-Directory/
WEB-INF/classes/entitydefs/entitymodel.xml to use extremely-long which is CLOB by default.
In either case, drop and re-create the database to have JIRA re-populate the schema with the new definitions (or manually move the data to another table with the new definition and swap it with the previously defined object).
