Re: Threadsafety of the PersistenceBroker default impl

[James Nyika <ja...@novell.com>]

Hi
 I am a newbie to OJB and i am using the PB api and i would like to
access a single instance
 of the broker to perform CRUD operations. 

 1. Is the default impl of the broker threadsafe or should i
synchronize all my calls
 2. is there any other suggestion on an implementation, or a pointer to
a doc that explains some options i could use.

 sorry if this has been answered already, but i scoured the default
docs, examples and list .. to no avail.

Hi James,

The PB is intended to be used only for one tx at a time. Using a single 
PB instance from multiple thread will work only if all threads are 
expected to work within one and the same jdbc tx.
If you want to have each thread to use it's own jdbc ty use one PB 
instance per thread.

cheers,
Thomas
