[ebxmlms-develop] Transaction Isolation Level Configuration

[Jason v. Z. <ja...@ze...>]

Hi,

I have a tarball with modifications to hermes to allow the transaction
isolation level to be configured by the user if desired:

http://www.apache.org/~jvanzyl/xa-isolation-levels.tgz

I have modifed:

hk.hku.cecid.phoenix.message.handler.Constants
hk.hku.cecid.phoenix.message.handler.DbConnectionPool
hk.hku.cecid.phoenix.message.handler.DiagTool
hk.hku.cecid.phoenix.message.handler.MessageServer

and added:

hk.hku.cecid.phoenix.message.handler.IsolationLevelSelector

It simply allows users to do the following:

<Driver>org.axiondb.jdbc.AxionDriver</Driver>
<User>user</User>
<Password>password</Password>
<URL>jdbc:axiondb:hermes:/tmp/hermes/db</URL>
<TransactionIsolationLevel>SERIALIZABLE</TransactionIsolationLevel>
 
If a transaction isolation level is not specified at all or
misconfigured then the current behavior is employed where the most
rigorous isolation level is used.
