ORA-22813: operand value exceeds system limits

问题

I'm having an issue with an oracle object I created. The goal of the stored procedure is to either retreive all wires contained on an airplane or compare the list of wires with another one (past airplane wire configuration). You will understand that this can be quite big... I did a first shot with a table of objects. I make a select statement and loop through a cursor to insert values in my objects. The problem comes from when I try this:

OPEN P_CURSOR FOR
  SELECT * FROM TABLE(CAST(GET_WIRES(P_ACTUAL_HAR_LIST, P_END_IDENT_TYPES) AS TBL_TP_WIRE_LIST));

I get the ORA-22813: operand value exceeds system limits. So, I started looking on the internet and I found that I should have used a PIPELINED function, which I tryied. But, the PIPELINED function is not allowed in a PL/SQL context, so that doesn't fit my problem, since I need to rework the object afterward. So, I tryied a Global Temporary Table and I have now performance issue. I also tryied to contact the DBA if he could increase the PGA size, which he did (it's now 150mb) but I have the same problem. Maybe it's still not big enough, but I don't want him to reincrease it if it's not going to work... Just so you have an idea, I have 1 487 761 of those:

I ran into a similar situation in a data warehousing environment at a past job.

Did your DBA increate pga_aggregate_target or _pga_max_size or both? Keep in mind that when the DBA increases pga_aggregate_target to 150MB that doesn't mean that your session would be able to grab all of that 150MB. Oracle will only allow a given session to take a small fraction of that space. Increasing pga_aggregate_target from 150MB to 200MB will only give your session a few extra megs of memory to play with for in-memory operations IIRC.

If your DB server has more available memory, you'll have to have your DBA increase both pga_aggregate_target and _pga_max_size, otherwise you'll have to look at using a GTT or creating a scratch table to dump your data into and then work on it from there.

Just wanted to add this tidbit in case it helps someone else. We suddenly started getting this error in our PL/SQL when the DBA set RESULT_CACHE_MODE to AUTO as a test for another process. We didnt know he did this until much later. Anyway, setting it back to MANUAL fixed this problem.
