Martin Vecera commented on JBMESSAGING-1359:
--------------------------------------------
Of course, we tried googling this. We also tried DBCC shrink commands. But it doesn't
reclaim any space. Those commands can reclaim a free space in data files but according to
the report the table JBM_MSG needs that space. So your google results are off topic. We
also tried googling for the specific problem, but without success.
Currently, JBM cannot work with MS SQL. And I don't know if this is due to the fact
that you need to execute any extra non standard commands...
JBM is not able to work with MSSQL - MSSQL not cleaning deleted rows
from JBM_MSG table, not reclaiming disk space

Key: JBMESSAGING-1359
URL:
http://jira.jboss.com/jira/browse/JBMESSAGING-1359
Project: JBoss Messaging
Issue Type: Bug
Components: Messaging Core Persistence
Affects Versions: 1.4.0.SP3.CP02
Environment: SOA-P 4.2 CP02, RHEL5, MSSQL
Reporter: Martin Vecera
Assigned To: Tim Fox
Priority: Critical
Attachments: dbstat.csv.gz, jbm_msg.csv.gz, soaesb1_dbstat.sql.gz
Reproducible: 100%
Description: There is something that prevents MSSQL to clean deleted rows from JBM_MSG
table and the disk space occupied by that table grows permanently.
I had HelloWorld ESB service listening on JMS queue. I was constantly sending messages to
that queue. JBM_MSG table contains around 1000 in average - this is balanced between
sender and receiver. Consumer consumes old messages, new messages are still arriving.
Every message has 5kB.
The DB grows in size during this procedure until it takes the whole disk space and make
the DB unusable for JBM.
Evidence - attached files:
dbstat.csv - status report for all the tables in DB - see RowCount, DataSpace for
JBM_MSG
jbm_msg.csv - content of JBM_MSG table when status report was generated
soaesb1_dbstat.sql - SQL script for generating status report
Caution: MSSQL is required in SOA-P PRD. If this cannot be solved, the requirement should
be removed.
