RDB/JDBC native driver

ptrskg — Thu, 26 May 2005 12:34:51 GMT

Hi,

I have for some time now used the the RDB/JDBC thin driver(pool) to access RDB db's on VMS. Now I plan to move some java app's to the VMS server and then start to use the native driver to avoid IP overhead.
But I'm afraid that this will give me trouble, I suspect that the db-accesses will be "syncronized" as RDB only allows one connection to a DB from a process?. The java process have many threads accessing the DB. Have anyone experience in this area?

Greateful for any advice/tips.
Peter

Rdb is not multithreaded so a process with several threads can not
execute Rdb requets in // in several threads.

you should test, send a huge request and then in // a small one, you will see if the small is waiting

You could try to see on jcc (the Rdb mailing list) if this is known (http://jcc.com/listserver.htm) or search in their database http://jcc.com/searchengine.asp

Good luck
