Hi all,
This is my datasources definition:
- <local-tx-datasource>
<jndi-name>AmsDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/ams_db</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>jboss</user-name>
password
<transaction-isolation>TRANSACTION_READ_UNCOMMITTED</transaction-isolation>
<min-pool-size>1</min-pool-size>
<max-pool-size>200</max-pool-size>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
-
<type-mapping>mySQL</type-mapping>
</local-tx-datasource>
As you can see, I set the transaction isolation level to READ_UNCOMMITED.
However, when I restart jboss, when I try to persist an entry from transaction A, and then , inside the transaction code to select the persisted entry, I get that the entry does not exist. Both insertion and selection are done using EntityManager.
I thought that using READ_UNCOMITTED means that I can read any uncommited changes made by any transaction.
Can anyone explain me what I'm doing wrong?
Thanks
Yair Zaslavsky
