Parallel Query on a Partitioned IOT Issue

Shivanischal A


Hi All,

A parallel query on a Range Partitioned IOT is exiting with the below

ORA-12801: error signaled in parallel query server P024
ORA-00904: "A1"."rowid": invalid identifier

The oracle version is on AIX 5.2

The query is like this:

  usage AS
    SELECT id1, SUM(v1) AS tv1
    FROM range_partitioned_iot
    WHERE date_field BETWEEN :StartDate AND :EndDate
    GROUP BY id1
  (rpi.v1/u.tv1) * 100
  ROUND(rpi.v1/60, 2)
  usage u,
  range_partitioned_iot rpi
  rpi.flag= 1 AND
  rpi.id1 = u.id1

Please note that the query has pseudo column and table names, but the
query is real. range_partitioned_iot is the paritioned IOT. All columns
except v1, v2, v3 are part of the primary key. The table was created
with the PARALLEL option. I noticed PQ errors only on partitioned IOTs.
I noticed PQ errors on the partitioned IOTs only when the query includes
the WITH clause.

I came up 3 (unacceptable) ways to solve the problem:
1. alter table range_partitioned_iot NOPARALLEL ;
2. replace the WITH with SQL Analytic functions (I have more complex
queries where I use up to 4 WITH clauses, so SQL Analytics cannot help
me and I categorized this method as unacceptable)
3. Recreate all my partitioned IOTs as Heap tables. Something I would do
the last thing in the world.

Facing client pressure, I chose the first as an interim measure. Gurus,
please advise whats wrong here. I have been to asktom, metalink and
found nothing that was of use. Maybe I was not looking properly....

Thanks for your time,
