Subject [jira] [Updated] (DERBY-5858) java.sql.SQLException: nospc.U trying to update a row
Date Fri, 14 Sep 2012 16:03:07 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5858?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mike Matrigali updated DERBY-5858:
----------------------------------

    Labels: derby_triage10_10  (was: )

triaged for 10.10

without a repro not much can be done.   Should leave open to track issues in the field in
this area.  
There have been fixes in the past so anyone running into this issue should upgrade to the
most
recent release possible.  The fixes in this area tend to not fix existing issues, but instead
prevent
future problems.  Usually running SYSCS_UTIL.SYSCS_COMPRESS_TABLE fixes the problem in
these cases.

>          Issue Type: Bug
>          Components: Store
>    Affects Versions: 10.8.2.2
>         Environment: Linux 2.6.18-194.el5    Java 1.6.0_23

> After browsing other issues, it seems the error nospc.U should not be thrown whenever
there is still space in the disk.
> The issue is that I have a table with about 80k rows and 3 rows for some reason became
corrupted, The rows where inserted about the same time. The rest of the table and the DB is
working ok for weeks until I noticed the problem with those 3.
> The error is triggered when I try to set a value update in the timestamp column in any
of those 3 rows. If I set that column to null it allows me to update other columns.
> I'm not sure if it is related but I have added 3 other columns to that table after it
was created but not the timestamp one that is failing.
> The way I worked around this problem was dropping and recreating the timestamp column.
> Following the derby log, the problem is in the column named "last_update":
