CODECREATE TABLESPACE my_ts DATAFILE 'C:\Oracle\oradata\db\my_ts.dbf' SIZE 5M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K;
ALTER DATABASE DATAFILE 'C:\Oracle\oradata\db\my_ts.dbf' AUTOEXTEND ON;
Its was sucessfully created and my_ts.dbf file has 5MB
charging with data...
CODEcreate table big_table tablespace my_ts as select * from dba_objects;
select * from big_table;
begin
for i in 1..10 loop
insert into big_table select * from dba_objects;
end loop;
end;
Now the my_ts.dbf file has 90MB
Now I want drop this table:
CODEdrop table big_table purge;
And my tablespace file still has 90MB.
I already tried to restart the database but doesn't works...
We are using a GTT table to store the summarize data and display it on same screen(10g 10.2.0.5). Now we are facing temporary tablespace space issue very frequently as our client do not enable the auto extend on for temp table space. We have analyzed the AWR and came to know that there are 900000 inserts per hour on an average. Client DBA Claims that there are sessions(1or 2) which inserts the data in temporary table continuously for 2-3 days.
According to him one session is running from 28th Aug and problem comes on 2nd Sep and after killing the problematic session the application will work fine. Generally this problems come on weekend. I have discussed with our dev team and as per them there is no session leakage issue.
following is the insert statement: INSERT INTO DT_CA_STNDALN_DETAILS_TMP (ORG_ID,BA_PRODTYPE_ID,MAX TENOR,GROSSLIMIT,GROSS_UTILISATION,HAS_MDR,HAS_CLUSTER,SIGN_IN D,GROSS_AVAILABILITY,COLLATERAL,NET_UTILISATION,DT_CA_STNDALN_DE TAILS_TMP_VER,DM_LSTUPDDT,NET_AVAILABILITY) VALUES (:1,:2,:3,:4, :5,:6,:7,:8,:9,:10,:11,:12,sysdate,:13) ;
I know this has been done to death, but I wanted to just go over what I do when OEM alerts me to a tablespace running out of space.First, I check the free space of the tablespace using this query:
SET LINESIZE 100COLUMN TABLESPACE FORMAT A15select t.tablespace, t.totalspace as " Totalspace(MB)",round((t.totalspace-fs.freespace),2) as "Used Space(MB)",fs.freespace as "Freespace(MB)",round(((t.totalspace-fs.freespace)/t.totalspace)*100,2) as "% Used",round((fs.freespace/t.totalspace)*100,2) as "% Free"from(select round(sum(d.bytes)/(1024*1024)) as totalspace,
In My database rollback segment space is not releasing space even though, there is no transaction is using RBS. RBS tablespace size is around 70GB. Unfortunately still our environment is running in 9i due to application code

Application team requested hosting team to add some space to tablespace as it was exceeding 80% used.Now the hosting team have added the space as per recommendation and the application team wants us to verify if the space was added. How to check the space was added in GB to list of tablesapces ?
Mistakenly I added lot of datafiles with autextend on option.. I realized later and then tried to resize the datafiles to a minumum space but got the below error
ORA-03214: File Size specified is smaller than minimum required.
How to resolve this problem to reclain the space back?
How to check for the increment of a space of the tablespace based on the particular table. (i.e.) Say a scenario, if am trying to load the data for a particular table, for first I loaded some 10000 records and then again loading 50000 records ,so based on the icrement of the reocrds the tablespace size also increases gradually . so for this scenario how to monitor the increment of the space.
We are using Oracle 10g and have 10 tablespaces defined for our Database which have 108 tables. Size of 108 tables is around 251 MB as seen during importing the dump. While creating these 10 tablespaces I used below parameters for allocation of space
SIZE 1M REUSE AUTOEXTEND ON NEXT 1M MAXSIZE 1M;
which set the initial space for 10 tablespaces to around 1032Kb each. Now my Question is after importing the dump , how the disk space for 10 tablespaces increases to 398 MB in total ?
Is there any relation of Tablespace disk space and Actual Data present in the tables ?
I have read and used the AWR script (mentioned in the page Finding unused index for finding unused customised (Z) indexes in our SAP system using oracle 10.2.0.2 as the SAP database.
But this returns no rows. Is there any precondition? I want to know how much / many times the indexes are used...We are smelling that lot of unused index are there in the database.
I have been trying to drop an unused column in a partitioned table, and the number of records stored in this unused column was very high. I kept on running into errors as follows:
ORA-01562: failed to extend rollback segment number 10
ORA-01650: unable to extend rollback segment R09 by 256 in tablespace RBS
I tried to "SET TRANSACTION USE ROLLBACK SEGMENT <name>" with a larger rollback segment, but it still did not work. Can I drop the "unused column" from each partition instead?
How to apply that? Or, what are my options besides increasing the size of the rollback segment?
If you mark a column unused, is there any way to project it? I know the docs say you can't, but as the data is still there I would have thought it should be possible. I can see the column in dba_tab_cols, but the obvious ways of making it usable don't work:
orcl> select column_name,hidden_column from user_tab_cols where table_name='DEPT';
COLUMN_NAME HID ------------------------------ --- LOC NO DNAME NO DEPTNO NO
orcl> alter table dept set unused column loc;
Table altered.
orcl> select column_name,hidden_column from user_tab_cols where table_name='DEPT';
COLUMN_NAME HID ------------------------------ --- SYS_C00003_13071316:19:02$ YES DNAME NO DEPTNO NO
orcl> select "SYS_C00003_13071316:19:02$" from dept; select "SYS_C00003_13071316:19:02$" from dept * ERROR at line 1: ORA-00904: "SYS_C00003_13071316:19:02$": invalid identifier
orcl> alter table dept rename column "SYS_C00003_13071316:19:02$" 2 to loc; alter table dept rename column "SYS_C00003_13071316:19:02$" * ERROR at line 1:ORA-00904: "SYS_C00003_13071316:19:02$": invalid identifier
orcl> alter table dept modify "SYS_C00003_13071316:19:02$" 2 visible; alter table dept modify "SYS_C00003_13071316:19:02$" * ERROR at line 1: ORA-00904: "SYS_C00003_13071316:19:02$": invalid identifier
I am in the task of clean up of tables. I need to find the list unused tables and procedures. Is there any way where i can find when was the last time the table queried?
Give sql query to find the list of unused tables and procedures.
what happens if you mark a column unused in a compressed table and then alter table drop unused columns? We had a customer do this and Oracle threw a -3113 (end of communication) error. They did a system restore before contacting us and blew away any evidence in alert logs/trace files. They did this on a 400GB compressed table.
My question is, when you drop an unused column off a compressed table, does it uncompress? Where does this uncompression occur? In the instances default tablespace? In the tablespace configured for the table?
Basically, we are wondering whether the error was due to poor error-handling of the system running out of space during decompression and trying to see if we can reproduce it. This was on an 11.1.0.7 system.
Sysaux Tablespace is running low. WE SET AWR RETENTION TIME=60 DAYS. WE ARE NOT INTEREST TO EXTEND SYSAUX TABLESPACE SIZE. Usually we take AWR weekly once. Some times we did ADDM report and ASH.
CODEsql>select TABLESPACE_NAME, FILE_NAME, BYTES/(1024*1024), AUTOEXTENSIBLE, MAXBYTES/(1024*1024) from dba_data_files where tablespace_name = 'SYSAUX';
1. What's the best SOLUTION ? 2. Can i shrink sysaux tablespace ? 3. I think , The size for all occupants in sysaux tablespace is less than 200 MB => how to find actual content of sysaux tablespace ? 4. What could be the reason for growth? Is there any way to free the space from sysaux table space?
We are using the following statement to obtain a row lock in a table in the database(ORACLE 10G), SELECT * FROM {TABLE_NAME} WHERE ID = 1 for update and if we succeed grabbing the row lock we will continue to issue a update statement every 30 seconds to preserve the lock as far as possible. here is the update statement to preserve the lock,
UPDATE {TABLE_NAME} SET time = ? WHERE ID = 1.
As you see more longer we keep holding the row lock , more update statements are submitted in the pending transaction. In normal case our application can grab the exclusive row lock and works for a long time,however sometimes a connection reset exception is thrown and our application will close the connection(I assume the pending transaction will be rolled back by the database) and exit the JVM. Since other applications will keep trying to grab the same row lock to become the master role, we expect one of them can succeed but they are all failed because the database has not released the row lock as expected. how and when the row lock can get released in our use case?
assuption is that when we truncate the partition it immediatly release the allocatd storage.i have just tested the scenario , but still i can see that table size is same even after truncating the partition( which have around 25% of the data)
alter table test truncate partition t1p3 update indexes ;
OR
alter table test truncate partition t1p3 drop storage update indexes ; to see the table size:
SELECT owner, table_name, TRUNC(sum(bytes) / 1024 / 1024) Meg FROM (SELECT segment_name table_name, owner, bytes FROM dba_segments WHERE segment_type = 'TABLE' UNION ALL [code]...
am trying to downgrade my oracle database 10g release 10.2.0.2.0 to 10.2.0.1.0the reason for this is that i had to copy /oracle_home/bin utilities from 10.2.0.1 to 10.2.0.2 because of this most utilities like rman,dbca were not working.
i think i need to downgrade my oracle database 10g release to 10.2.0.1.0 right?i read some oracle documentations of database downgrade instruciting me to
>take full backup of oracle DB >ORACLE_HOME/bin/emctl stop dbconsole SQL> STARTUP DOWNGRADE DROP USER sysman CASCADE; >SQL> SPOOL downgrade.log
Share 11g Release 2 Grid infrastructure and RAC installation experience on Sun SPARC. Any documentation which provide complete information from server setup to database setup.
Ours is Oracle 11.2.0.2.0 Db 4 instances RAC on Unix AIX OS.Since long we are facing problem that CPU utilization reached 100% and reboot is required alteast once or twice a month.On seeing the Events Logs we find that the Event "CURSOR PIN S WAIT FOR X" is consuming a lot of waits.
On analyzing i came to know that we are firing same query from Application 15 to 20 lack times for which a lot of Mutex keeps spining for getting Shared Mode and consumes a large amount of CPU.
