My web application project requires mapping of update queries to stored procedures in Oracle (instead of directly generated update queries), using Oracle 10 and ojdbc14. EclipseLink version is 2.3.2. When I wanted to implement and verify the solution on one of entity classes, I found out that some (something like 15) of 60 storage procedure parameters could not be bound (which was also reported in the log).
At the end I found out that most probably the total lenght of parameter names was the cause (each approximately of 10-30 characters). When I used the shortest parameter names possible like p01..p60 in my stored procedure, it suddenly started working as expected.
Is it a known limitation or a well hidden bug?

I am sorry for not including more info but I really do not want to publish my database structure here and I have no time to make more debug on a separate test project at the moment (maybe later). I believe that the problem can be replicated even with this brief description.

This sounds like a database issue, the database may have a maximum SQL string size that you are somehow exceeding. You will need to use the shorter parameter names.

Including the generated SQL, and your code would help.
