DB13 Check and update optimizer stat error: ORA-01652: unable to extend tem

Question

Hi SAP Gurus,
When running Check and Update Optimizer Statistics in DB13, an error occurs.
BR0280I BRCONNECT time stamp: 2011-03-10 06.35.52                    
BR0301E SQL error -1652 at location stats_tab_collect-16             
ORA-01652: unable to extend temp segment by 12137 in tablespace SYSTEM
BR0886E Checking/collecting statistics failed for table SAPR3.ACCTIT 
BR0280I BRCONNECT time stamp: 2011-03-10 06.36.49                    
BR0850I 3 of 39479 objects processed - 3.522 of 342.781 units done   
BR0204I Percentage done: 1.03%, estimated end time: 15:47            
Looking at tablespace SYSTEM in DB02, the percent used is 58. Auto-extent feature is OFF. Will turning the auto-extent ON, remove the error?

Answer 1

It seems like Your user (by a mistake) have tablespace SYSTEM as temporary tablespace.
Connect as sysdba in Your database and check which temp tablespaces awaiable, and size of them:
select tablespace_name, sum(bytes)/1024/1024 "Size of TEMP TBS in MB" from dba_temp_files  group by tablespace_name;
Check which users having SYSTEM as tamp-tbs:
select username, temporary_tablespace from dba_users where temporary_tablespace like 'SYSTEM' order by 1;
Change those users to have one of your temp-tablespaces:
alter user &username temporary tablespace &&TempTBS;
It's also a good idea to have autoextend on on Your temp TBS, but remember to set maxsize so you doesn't fill up your disksystem.
Hope this solve Your problems.
