Len DiMaggio commented on JBMESSAGING-1359:
-------------------------------------------
Adding a piece of an email from Martin - providing background on the test and problem:
JBM_MSG table is used just as a persistent storage of undelivered
messages. Once the message is delivered, it is removed from the table. It
behaves like queue in fact. After sending 500,000 there are around 5,000
messages in that table and the table takes over 2GB. How many KB the table
takes can be easily revealed by this script:

Oracle doesn't grow in size, but slows down. This "could" be the same
problem.
JBM is not able to work with MSSQL
----------------------------------
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.
