I really can't find any other solution for what I need (in short: make sure no transactions are left out due to serialization failures)
I think you may have been too quick to rule out advisory locks as a solution. Yes, you will need wrappers around all other calls, but extraordinary problems call for extraordinary solutions.
I could place the locks from the adapter directly at the outer transaction level but I have the feeling that performance would be worse...
Well, performance has really got to take a back seat, given your other requirements. ;) Locking certainly *could* work - and is arguably the best solution, as that's what locks are for. Just have your Very Important Transaction retry, and upon reaching that critical number, exclusively lock just the tables being used, then try again. If you don't know which tables are being used, I suggest storing that somewhere your class can find it, or moving away from such a generic class. There are other solutions (e.g. forcing conflicting processes to quit and sleep a second), but the locking one seems the easiest. - -- Greg Sabino Mullane greg@turnstep.com End Point Corporation
