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 https://www.tekstream.com/resources/ora-12801-error-signaled-in-parallel-server/ into this category, an Oracle error emanating most often in response to errors when processing 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 S
3:46 pm UTC Category: Database � Version: 8.1.7 Whilst you are here, check out some content from the AskTom team: Granular detail from a summary Latest Followup You Asked https://asktom.oracle.com/pls/asktom/f%3Fp%3D100:11:0::::P11_QUESTION_ID:1027523970333 Tom, Suppose I have enabled parallel query on one of the tables out of 50 in my application..Then if I query using a join between those tables (only one of them is parallel query enabled ) then would Oracle still use the parallel query when running that query. If not, is there something like a hint to make Oracle use the parallel query error signaled against that table. eg...EMP table with 1 million rows and parallel query enabled. DEPT with 1000 rows and parallel query NOT enabled. Then the following query will it use the parallel query on EMP table. Select * from EMP, DEPT WHERE emp.deptno = dept.deptno; Thanks, Suresh and we said... Any operation that could be parallelized against that table in any query would be error signaled in a condidate for parallelization (against that table) You can always add the parallel hint to the query. As for your question -- it might, it might not. Depends on what table is driving the query. If we full scan DEPT and index access EMP, no -- most likely a serial operation. If we full scan EMP and index access DEPT -- probably. If we full scan both, probably. Easy enough to see what'll happen (dbms_stats is great for this "what if" stuff) ops$tkyte@ORA817.US.ORACLE.COM> create table emp as select * from scott.emp where 1=0; Table created. ops$tkyte@ORA817.US.ORACLE.COM> create table dept as select * from scott.dept where 1=0; Table created. ops$tkyte@ORA817.US.ORACLE.COM> ops$tkyte@ORA817.US.ORACLE.COM> alter table dept add constraint dept_pk primary key(deptno); Table altered. ops$tkyte@ORA817.US.ORACLE.COM> alter table emp add constraint emp_fk foreign key(deptno) references dept; Table altered. ops$tkyte@ORA817.US.ORACLE.COM> create index emp_fk_idx on emp(deptno); Index created. ops$tkyte@ORA817.US.ORACLE.COM> ops$tkyte@ORA817.US.ORACLE.COM> ops$tkyte@ORA817.US.ORACLE.COM> exec dbms_stats.set_table_stats( USER, 'EMP', numrows => 1000000, numblks => 100000, avgrlen=> 700 ) PL/SQL procedure successfully completed. ops$tkyte@ORA817.US.ORACLE.COM> exec dbms_stats.set_table_stats( USER, 'DEPT', numrows => 1000, numblks => 13, avgrlen=> 100 ) PL/SQL procedure successfully completed. ops$tkyte@ORA817.US.ORACLE.COM> ops$tkyte@ORA817.US.ORACLE.COM> alter table emp parallel 5; Table alte
