Question

I have a SP in DB A - PROC A1
In DB A, PROC A1 sequentially calls PROC A2 and PROC A3
In PROC A2, I call a procedure PROC B1 in instance B using a db_link. PROC B1 inserts a record in table B.X. This happens for a number of records.
Once PROC A2 is complete, PROC A1 calls PROC A3.
PROC A3 queries table B.X via a public synonym using the same db_link as the proc call in PROC A2. PROC A3 is looking for the records inserted by PROC A2.
I have a test environment where DB A and DB B (and associated db_links) are set up without load balancing. In this environment, PROC A3 sees the records inserted by PROC A2.
I have a prod environment where DB A and DB B (and associated db_links) are set up with load balancing. In this environment, PROC A3 does NOT see the records inserted by PROC A2.
HELP!

Posting without version is, as always, dangerous.
I remember in Oracle 9iR2 (although don't ask me for the doc page), Oracle specifically states, one shouldn't use load balancing in setting up database links.
My gut feeling says this is the kind of issue why they state this.
