原因

The AO_60DB71_LEXORANKBALANCER has information relating to a non-existent field on AO_60DB71_LEXORANK table.

ソリューション

To resolve this problem, perform the steps listed below:

We strongly recommend to keep a database backup at this point. The next steps will require delete operations and, in case of failures, a rollback might be needed.

1. Jira をシャットダウンします。

2. Run the following query on the database:

   SELECT * FROM "AO_60DB71_LEXORANKBALANCER" WHERE "FIELD_ID" = <field_from_error_message>;

   If the query above returns no rows where the "FIELD_ID" is the same mentioned on the error message, do not proceed to next steps and inform Atlassian Support!

3. Run the following statement, replacing the field id accordingly:

   DELETE FROM "AO_60DB71_LEXORANKBALANCER" WHERE "FIELD_ID" = <field_from_error_message>;

4. Restart JIRA and run a full re-index
