protected Object executeInLock(String lockName,
    TransactionCallback txCallback) throws JobPersistenceException 
{
        return executeInNonManagedTXLock(lockName, txCallback);
}

Execute the given callback having optionally aquired the given lock. For JobStoreTX, because it manages its own transactions and only has the one datasource, this is the same behavior as executeInNonManagedTXLock().

 protected Connection getNonManagedTXConnection() throws JobPersistenceException 
{
        return getConnection();
}

For JobStoreTX, the non-managed TX connection is just the normal connection because it is not CMT.

 public  void initialize(ClassLoadHelper loadHelper,
    SchedulerSignaler signaler) throws SchedulerConfigException 
{
        super.initialize(loadHelper, signaler);
        getLog().info("JobStoreTX initialized.");
}
