Subject [jira] Updated: (JS2-1025) Mysql maven2 build error - UNIQUE INDEX key too long
Date Tue, 02 Jun 2009 07:10:07 GMT

     [ https://issues.apache.org/jira/browse/JS2-1025?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ate Douma updated JS2-1025:
---------------------------

    Priority: Minor  (was: Major)

The problem really is with MySQL, this is not a Jetspeed bug.
The unique index cannot be made shorter without a complete object remodelling, we need all
these columns in the index as it represent a *logical* model constraints.
The fact you're overrunning the *mysql* limit of 1000 bytes key length indicates you most
likely are using an extremely long preference name.
I suggest trying to reduce your preference name length as easiest solution here.

> While building a custom j2.2 portal I got the following error:
> Embedded error: Failed to execute:   CREATE UNIQUE INDEX UIX_PORTLET_PREFERENCE
> ON PORTLET_PREFERENCE (DTYPE, APPLICATION_NAME, PORTLET_NAME, ENTITY_ID, USER_NA
> ME, NAME)
> Specified key was too long; max key length is 1000 bytes
> [INFO] ------------------------------------------------------------------------
> [INFO] Trace
> org.apache.maven.lifecycle.LifecycleExecutionException: Unexpected error
> I think that the:
> CREATE UNIQUE INDEX UIX_PORTLET_PREFERENCE ON
> PORTLET_PREFERENCE (DTYPE, APPLICATION_NAME, PORTLET_NAME, ENTITY_ID, USER_NAME, NAME)
> query needs to be replaced with a shorter index e.g. (DTYPE, APPLICATION_NAME, PORTLET_NAME)
but I do not know about side effects.
> Please provide fix and deploy also to jars as people cannot build custom portals with
j2.2 / mysql
