Each time Confluence restarts, this warning appears in the log:
1
2010-08-25 22:21:17,428 WARN [main] [atlassian.plugin.manager.DefaultPluginManager] addPlugins System plugin is disabled: confluence.search.mappers.lucene
The following appears in the atlassian-confluence.log:
1
2010-08-25 22:29:58,964 WARN [http-8331-1] [v2.lucene.compatibility.V2SearchSmartListManager] getListQueryResults Could not perform search produced by ListQueryToSearchConverter.
Cause
The system plugin that handles the index mapping (confluence.search.mappers.lucene) is disabled. To verify, run the following query against your database:
1
select * from BANDANA where BANDANAKEY='plugin.manager.state.Map';
This will return a value like:
1
2
3
4
5
6
7
8
<map>
...
<entry>
<string>confluence.search.mappers.lucene</string>
<boolean>false</boolean>
</entry>
...
</map>
Resolution
Always back up your data before making any database modifications. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.
Remove the following entry from the results above and retain the rest:
1 2 3 4<entry> <string>confluence.search.mappers.lucene</string> <boolean>false</boolean> </entry>To perform this, use this SQL query:
1 2 3 4 5update BANDANA set BANDANAVALUE='<map> <your other XML> </map>' where BANDANAKEY='plugin.manager.state.Map';Restart Confluence after this modification.
