Mike Matrigali commented on DERBY-5234:
---------------------------------------
I am not surprised that SYSCS_UTIL.SYSCS_COMPRESS_TABLE fixed the problem, as
it seems the issue is in just the last few pages of the file that are marked
free but not actually on disk. This version of compress which I refer to as
offline, just reads through the used pages of the file and inserts into the new
table and never looks at the problem empty and not on disk pages at the end of
the file.
> Unable to insert data into table. Failed due be "ERROR XSDG0: Page
> Page(51919,Container(0, 1104)) could not be read from disk."

> Key: DERBY-5234
> URL: https://issues.apache.org/jira/browse/DERBY-5234
> Project: Derby
> Issue Type: Bug
> Components: JDBC, Network Server, SQL
> Affects Versions: 10.5.3.0
> Environment: HP-UX 11iv2 in production environment with JDK1.6;
> Solaris 5/10 in test environment with JDK 1.6
> Reporter: Varma R
> Labels: ERROR, XSDG0, apache, corruption, data, derby
> Attachments: DataFileReader_Output.zip

> One of the derby database table "gets corrupted"/"indicates connection not
> available" during processing inserts from java client application as shown in
> the trace and the only way to recover from this error is to rebuild the DB -
> by deleting the data and creating the tables again. This happens once in a
> while (thrice in a span of two months) and the java application (run in
> multiple servers), which updates the database, processes around 100 million
> transactions per hour (in total and each transation results in 4-5 updates to
> the DB)
> There are eight tables in the derby database.

> Cleanup action completed

> Can anyone help me out in identifying the problem that why for one table
> alone its throwing the above error message ? Would upgrade to a new version
