ParallelOra-01722: Invalid Number
query error ORA-12801 Oracle tips by Burleson Question: When running Oracle parallel query, I get a sporadic error like this: ERROR: ORACLE execute error: ORA-12801: error signaled in parallel query server P017 ORA-01652: unable to extend temp segment by 314 in tablespace TEMP. I understand the ORA-01652 as https://scn.sap.com/thread/803902 being caused by running out of space, but I do not understand the ORA-12801. Answer: Wow, P017, that's a lot of parallel query processes. Just make sure that you have enough processors to support this load. I've seen this ORA-12801 error pop-up intermittently for no apparent reason, usually when the server is especially active, and it's always the second message (in your case, http://www.dba-oracle.com/t_ora_12801_parallel_query.htm ORA-01652). MOSC note 184416.1 has details on diagnosing the ORA-12801 error. It notes that the ORA-12801 is somewhat generic and that you should look for more details in your alert.log or in trace files in the USER_DUMP_DEST or BACKGROUND_DUMP_DEST location. You can set event 10397 to get more details: ORA-12801, 00000, "error signaled in parallel query server %s" Cause: A parallel query server reached an exception condition. Action: Check the following error message for the cause, and consult your error manual for the appropriate action. *Comment: This error can be turned off with event 10397, in which case the server's actual error is signaled instead. In any case, the central question is why your parallel query was performing a sort, resulting in the ORA-01652 error? OPQ generally sorts as the final step, after the paralel processes have returned the result set to the parallel query coordinator (usually P00).The symptom solution, of course, is to increase the size of your TEMP tablespace, or better still, increase your sort_area_size. If this job is running batch, you can do this with an alter session command, as this this case, to one gig:

The downside is that in any system, dealing with huge amounts of data can naturally carry some headaches and frustration along the way. The ORA-12801 would most easily fall into this category, an Oracle error emanating most often in response to errors when processing error signaled in large jobs. The Problem The ORA-12801 is an Oracle error that has some confusing origins, but is described as an error resulting in some form from a parallel query server. The error frequently accompanies another error, often the ORA-01652 (which concerns an inability to extend the temp segment in a tablespace). The ORA-12801 is essentially a general error, a sort of catchall for parallel query issues. At this juncture, some of you may be wondering yourselves, “What is a parallel query?” First showing up in later versions of Oracle7, a parallel query option lets multiple processes request and receive data and perform operations at the same time. As you would imagine, this can greatly enhance the speed of the system. To achieve this kind of efficiency, there are several conditions for the parallel query that require attention. So what are those conditions and how do they pertain to resolving an ORA-12801 error? The Solution An absolutely crucial element in successful parallel query operation is the appropriate use of query slaves. If too few or too many are put to use, the system wil
the new Pluggable Database feature of the newly released Oracle 12c Database. I installed the software, created the database (see my post about the "ENABLE PLUGGABLE DATABASE" clause which I forgot the first time around) and then wanted to create a new Pluggable Database (PDB) like so: SQL> CREATE PLUGGABLE DATABASE kdb121p1 ADMIN USER simon IDENTIFIED BY tiger; CREATE PLUGGABLE DATABASE kdb121p1 ADMIN USER simon IDENTIFIED BY tiger * ERROR at line 1: ORA-00604: error occurred at recursive SQL level 1 ORA-00942: table or view does not exist Oh, really strange, what kind of error message is that? First off, I made sure my main database is a Container Database: SQL> select cdb from v$database; CDB --- YES Alright, so let's query some of the views that contain information about our databases (container and pluggable): SQL> desc cdb_pdbs; Name Null? Type ----------------------------------------- -------- ---------------------------- PDB_ID NOT NULL NUMBER PDB_NAME NOT NULL VARCHAR2(128) DBID NOT NULL NUMBER CON_UID NOT NULL NUMBER GUID RAW(16) STATUS VARCHAR2(13) CREATION_SCN NUMBER CON_ID NUMBER SQL> select * from cdb_pdbs; select * from cdb_pdbs * ERROR at line 1: ORA-12801: error signaled in parallel query server P001 ORA-00942: table or view does not exist Huh? How can it be that I can execute the DESCRIBE statement but not select anything from the view? Cause and Resolution These errors appear when the CATALOG.SQL, CATPROC.SQL and PUPBLD.SQL scripts were not executed using the catcon.pl script provided by Oracle. This means views for the data dictonary were only created in your root database (the CDB) but not in the seed database. This leads to the errors above. Run the scripts to create the catalog as follows: $ PERL5LIB=$ORACLE_HOME/rdbms/admin:$PERL5LIB; export PERL5LIB $ perl $ORACLE_
