I'm currently developing a system using OCI in a multithreaded environment.
I do have lots of trouble with accessviolations when calling the OCI
functions.
Especially when calling oopen from different threads, using a threadlocal
CDA and
a common LDA (session/connection) for all calls to oopen.
As soon as I serialize a transaction within critical section, meaning that
no cursor can
execute simultanously on the same LDA the problems seem to disappear.
Also if I make one connection for every cursor, the problems disappear.
Have anyone experienced similar problems or maybe know about
OCI-restrictions in
this matter ?
Thanks in advance
Mogens
