Varma R commented on DERBY-5234:
--------------------------------
Hi,
Tried the above options mentioned.
a) Given the below debug option which starting the derby database.
-Dderby.debug.true=CacheTrace,DaemonTrace,DeadLockTrace,LockStackTrace,LockTrace,LogTrace,memoryLeakTrace,ScanTrace,SerializedTrace,SpaceTrace,TEST_LOG_FULL
But this didn't print any additional information in the logs.
b) Below are the command output's on test environment.
-bash-3.00$ ulimit -a | grep file
core file size (blocks, -c) unlimited
file size (blocks, -f) unlimited
open files (-n) 256
-bash-3.00$ plimit 5036
5036: java -Dderby.system.home=/export/home/cmd -Dderby.locks.monitor=true -
resource current maximum
time(seconds) unlimited unlimited
file(blocks) unlimited unlimited
data(kbytes) unlimited unlimited
stack(kbytes) 10240 unlimited
coredump(blocks) unlimited unlimited
nofiles(descriptors) 65536 65536
vmemory(kbytes) unlimited unlimited
you can see that there are no limits on the file system and 65536 is the hard
limit for the file descriptors.
c) After running SYSCS_UTIL.SYSCS_COMPRESS_TABLE procedure on KPI.KPI_MERGEIN
table. INSERT command is working on KPI.KPI_MERGEIN table.
d) How to find out the list of .dat files corresponding to a table in seg0
directory?
This same application was load tested for higher transcation volume and no such
error were reported during development. However the problem in production seems
to be pointing to cumulative data/disk usage. Also would it be recommeneded to
run SYSCS_UTIL.SYSCS_COMPRESS_TABLE once in a while?
> 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
>
> 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.
