Description Michael Mráka 2009-03-04 04:43:46 EST
Description of problem:
check-oracle-space-usage.sh reports high usage on UNDO tablespace. Space in UNDO tablespace is recycled so it doesn't make a sense to report that.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. check UNDO tbs usage: 
 # su - oracle -c 'db-control report'
2. consume free space in UNDO_TBS (db session 1):
 # sqlplus rhnsat/rhnsat@rhnsat
 SQL> create table undoconsumer as select s.* from user_source s,
        (SELECT rownum FROM dual CONNECT BY LEVEL <= 1000) t1000;
3. create db session 2 (connect from another terminal) and run query against undoconsumer:
 # sqlplus rhnsat/rhnsat@rhnsat
 SQL> select count(*) from undoconsumer;
4. from db session 1 run:
 SQL> update undoconsumer set line = line+1;
5. wait until db session 1 ends or fails with ORA-30036 (it takes about 15 mins)
6. check if UNDO_TBS is exhausted:
 # su - oracle -c 'db-control report'
7. run space report
 # /etc/cron.daily/check-oracle-space-usage.sh

Actual results:
