[jboss-jira] [JBoss JIRA] Commented: (JBAS-2503) JBossMQ JDBC2 Blob workaround for Oracle 4k limit

JBossMQ JDBC2 Blob workaround for Oracle 4k limit ------------------------------------------------- Key: JBAS-2503 URL: https://jira.jboss.org/jira/browse/JBAS-2503 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public(Everyone can see) Components: JMS (JBossMQ) Affects Versions: JBossAS-3.2.7 Final, JBossAS-4.0.3 SP1 Reporter: Adrian Brock Assignee: Ryan Campbell Priority: Optional Fix For: JBossAS-3.2.8 Final, JBossAS-4.0.4.CR2, JBossAS-5.0.0.Beta1 Allow override of the blob processing and create a subclass of JBossMQ's JDBC2 persistence manager such that it can workaround the 4k limit of the thin driver. Effectively we translate: INSERT INTO JMS_MESSAGES (MESSAGEID, DESTINATION, TXID, TXOP, MESSAGEBLOB) VALUES (?,?,?,?,?) into INSERT INTO JMS_MESSAGES (MESSAGEID, DESTINATION, TXID, TXOP, MESSAGEBLOB) VALUES (?,?,?,?, EMPTY_BLOB()) SELECT MESSAGEID, MESSAGEBLOB FROM JMS_MESSAGES WHERE MESSAGEID = ? FOR UPDATE UPDATE JMS_MESSAGES SET MESSAGEBLOB = ? WHERE MESSAGEID = ? If we knew how to generically retrieve the primary key column and key values from the insert we could do this as a plugin to the JDBC resource adapter. But parsing SQL is not really an option.
