OATM- dropping old tablespaces

Hi,
After the OATM migration completes with the status report showing 100%, how should I go ahead with removing the old tablespaces?How to decide which tablespaces can be dropped and which cannot?
Regards,
Sandeep Sulakhe

Hi,
If you are on 11.5.10.2:
1) Run OATM migration utility-> perl $FND_TOP/bin/fndtsmig.pl
2) Choose "6" -> "Run Post Migration Steps"
3) Choose "4" -> "Generate script to drop empty tablespaces"
4) Execute the script generated
else (not 11.5.10.2):
You should drop old tablespaces manually.
Anyway take a full backup before.
Regards,
Aviad

OATM: Why to run Re-Size old tablespace

Hi,
During OATM migration, Post migration steps says "Select Option 3 to reduce the size of the old tablespaces".
Why this is required? We are going to drop all those old tablespaces later.
Is that step really required?

Shaiju

Is that step really required?Select Option 3 to reduce the size of the old tablespaces. This option queries the data dictionary for all data files of the previous tablespaces to determine the level at which they can be re-sized, and generates the resize commands in a script resizdb.sql. This script is then executed to resize the data files.

Cannot drop old undo tablespace. Cause: active rollback segment

dear all.
db: oracle 10.2.0.1
os: rhel as version 5 64 bits.
This is a testing database. And my database is online and open. But i can free the external usb disk that contains my ols undotbs.
I want to drop old undo tablespace but this is not possible.
1.- In order to open my database i had my datafile( '/mnt/hdext/back_plelds/undotbs02.dbf') offline drop, and then i can to open my database.
2.- When i try to delete my old undo tablespace im getting this error:
SQL> drop tablespace undotbs1 including contents and datafiles;
drop tablespace undotbs1 including contents and datafiles
ERROR at line 1:
ORA-01548: active rollback segment '_SYSSMU1$' found, terminate dropping
tablespace
3.- My default undo_tablespace is another that i was created before step 1.
SQL> sho parameter undo_ta

undo_tablespace string UNDOTMP
SQL>
Well i search in metalink ORA-01548 code error and in 18947.1 doc whows me that the solution is:
Action: Shut down instances that use the active rollback segments in the
tablespace and then drop the tablespace.
4.- I try to shutdown but im getting:
SQL> shutdown immediate;
ORA-00376: file 10 cannot be read at this time
ORA-01110: data file 10: '/mnt/hdext/back_plelds/undotbs02.dbf'

This /mnt/hdext is an external USB disk and i have all permissions. I exported tables without any problem and i can read all files.
i search un metalink again ora codes (ORA-00376 ORA-01110) and the doc id: 427801.1 shows in the solution:
Drop the old undo tablespace instead of making it offline.
but when i try to drop the tablespace it shows the error describe in the step 2.
Facts:
- my tablespace UNDOTBS1 is ONLINE. I put in offline and this is not the solution.
- This is the status of my rollback segments:

Cannot drop undo tablespace with Active extents but no active sessions

Hi all,
I am running on 10gr2 oracle database in a Linux 32 bit environment.
I have a corrupted undo datafile. I've been able to recover the datafile but still the alert logs is still showing that it is corrupted.
Now what I'm trying to do is to drop the old undo tablespace like the one discussed here Change undo tablespace in Oracle - Switch Oracle's Undo tablespace.
My problem is I have an Active extent but no active session corresponding to it:
SYS@ccasdb AS SYSDBA > SELECT a.name,b.status
FROM   v$rollname a,v$rollstat b
WHERE a.usn = b.usn
AND    a.name IN (
                  SELECT segment_name
                  FROM dba_segments
                  WHERE tablespace_name = 'UNDOTBS1'
                 ); 2    3    4    5    6    7    8
NAME                           STATUS

SYS@ccasdb AS SYSDBA > SELECT a.name,b.status , d.username , d.sid , d.serial#
2 FROM   v$rollname a,v$rollstat b, v$transaction c , v$session d
3 WHERE a.usn = b.usn
4 AND    a.usn = c.xidusn
5 AND    c.ses_addr = d.saddr
6 AND    a.name IN (
7               SELECT segment_name
8               FROM dba_segments
9               WHERE tablespace_name = 'UNDOTBS1'
10              );
no rows selected
but still cannot drop the undotablespace.
SYS@ccasdb AS SYSDBA > drop tablespace UNDOTBS1 including contents and datafiles;
drop tablespace UNDOTBS1 including contents and datafiles
ERROR at line 1:
ORA-30013: undo tablespace 'UNDOTBS1' is currently in use
Regards,
Tim

Yes i was able to recover the datafile but the alert_log kept on prompting that it is still corrupted. The datafile's status is online.
I want to kill the session/s contributing to the PENDING OFFLINE status of the rollback segment so I can already drop the undotablespace and so
that the alert log will stop prompting for that corrupted datafile in that UNDOTABLESPACE.
Can i Just alter the tablespace's datafiles to offline drop then just drop it. Then I drop the tablespace?

Drop Undo Tablespace taking more than 1 hr

Hi,
To give you background, I had given an "insert into .. select" command which was inserting 3 millions of rows of rowidth approx 5000 bytes. The window on which it was given, was closed by mistake.
After sometime when I checked the size of undo_tablespace, it was 5.5GB. I decided to create a new one and drop the old undo_tbsp.
I have successfully created new undo tablespace and changed the same in spfile also.
now when i am dropping the old undo tablespace, its taking long time. its almost an hour, but the tablespace has not been dropped yet.
I have given following command
drop tablespace undotbs_01 including contents;
Any idea, why is it taking so much time, and how long should I wait?
If someone can give me any other idea on how can I drop the tablespace, that will be great.
Regards,
Archana.

To give you background, I had given an "insert into .. select" command which was inserting 3 millions of rows of rowidth approx 5000 bytes. The window on which it was given, was closed by mistake.This could be the cause.
I wonder the killed/closed session doesn't hangup with a latch or lock.
Since the old undo tbs had active transaction, it might have to pending offline status. If so, you can drop it.

Dropping Undo Tablespace 9i

Hey Folks,
I really need some help here.
I'm trying to drop/recreate the undo tablespace (currently 25gig) Oracle 9i
When I try to drop the undo tablespace 'UNDOTBS1' I get the following error:
âORA-01548: active rollback segment '_SYSSMU1$' found, terminate dropping tablespaceâ
Here's what I have tried so far:
- Bounced the DB several times hoping to get rid of the reference to the active rollback segment. No luck.
- Created a new undo table space
- Tried 'Alter system set undo_tablespace=new_one' (noticed that 10 new rollback segs were created '_SYSMU11$..SYSMU20$' pointing to the new undo tablespace)
- I then performed an offline drop of the undo tablespace data file. After the offline drop, the system rollback segs SYSMU01$..SYSMU10$ went offline as would be expected.
- Even with the new undo tablespace, all other application tablespaces still use the old undo which due to the offline drop, no inserts, deletes, etc. will work.
After all the above, I still get the same error when trying to drop the undo tablespace.
Any ideas? Ideally I would like to be able to drop the undo tablespace and recreate it, but at this point I'd be happy to bring back the undo tablespace datafile so we can at least use the database again.
Thanks in advance!!
Colin

SQL> show parameters undo
undo_retention integer
10800
undo_suppress_errors boolean
FALSE
undo_tablespace string
UNDOTBS03
r.- The undo tablespace which the database is looking for is this one ( UNDOTBS03 )
What is strange about the lines above is that I have
all those params above commented out in my
\pfile\init.ora file (and have bounced the db).
Iâm not sure why they are still showing up.
r.- Perhaps your instance is started with the spfile instead of the init file
Here's what we did after the UNDOTBS1 tablespace
caused the disk to run out of space during a large
import (from now on we are going to use commit = y):
1. Created a new undo tablespace UNDOTBS03 - got
errors so instead we to created it as a temp
tablespace UNDOTBS03 which worked. r.- Yes, but that tablespace was created as a UNDO TABLESPACE ?
2. Tried to drop UNDOTBS1 got the following error
msg:
ORA-01548: active rollback segment '_SYSSMU1$' found,
terminate dropping tablespacer.- Of course, the database did not allow to drop it beacause there were pending transactions
3. SQL> alter system set undo_tablespace =
'UNDOTBS03' scope = both. Tried dropping UNDOTBS1.
Same error as in #2 above.r.- There were still pending transactions with the older undo tablespace
4. We then offline dropped the datafile associated
with UNDOTBS1 hoping that would then allow us to drop
UNDOTBS1. Same error as #2.r.- That was the worst you did. You can not drop a tablespace so...
5. Then tried creating a undo tablespace again:
Create UNDO tablespace undo_temp
datafile 'D:\oracle\oradata\usbperf\undo_temp.DBF'
size 25m autoextend on;
Error on line 0
Create UNDO Tablespace undo_temp
datafile 'D:\oracle\oradata\usbperf\undo_temp.
ORA-00604: error occurred at recursive SQL level 1
ORA-00376: file 2 cannot be read at this time
ORA-01110: data file 2:
'D:\ORACLE\ORADATA\USBPERF\UNDOTBS01.DBF'
So thatâs where we are. I'm guessing that the
original undo tablespace corrupted when it tried to
extend and ran of disk space?
Thanks again for the help.
Colin ok I can guide to solve this but you have to do what I am going to tell you step by step. Is this a production database ?

Drop Temporary Tablespace!

Hi All,
I have tried dropping my old temporary tablespace TEMP after making new TEMP2 as default.
All the users (checked in dba_users) are using TEMP2 as default temporary tablespace.
Now, issue is when I am trying to take TEMP offline and dropping it some of the users are not able to open the forms.
Please suggest, is it necessary that I must do this activity after taking a proper downtime or I can do it in business hours.
Thanks,
Anchorage

It's done now!!!
Actually issue was
You cannot drop a tablespace if it contains any rollback segments holding active transactions.*
Try to check whether any one using the temp segments or not on query "v$sort_usage"*
If it returns the rows, the sessions are using the temp tablespace. Once the Sessions Closes then the the command execution will be completed, else you and go head and kill the session with respect to session Id.*
Which was been explained to me by Pavan in General Database Forum!
I have killed the active session and it was success!

Drop temp tablespace goes forever

Hi,
Trying to drop temp tablespace.
I made new default temp tablespace and that part went fine. I can see system using it immediately.
Then I tried to drop the old one.
drop tablespace temp including contents and datafiles;
.... no go .... altough content is gone now. Tablespace was full before this now it's empty.
My command still hangs in sqlplus.
Any idea?
Oracle 10.2.0.1 on Linux x86.

You either wait until it's finish. Or kill the session that held it.
SELECT s.sid,
       s.serial#,
       s.osuser,
       s.program
FROM   v$session s;
ALTER SYSTEM KILL SESSION 'sid,serial#'

Drop rollback tablespace after using UNDO

I have switched to using UNDO instead of using rollback segments. The UNDO works fine, and I have sucessfully dropped all rollback segments. Now I try to drop rollback tablespace. Can I simplely issue drop tablespace command to drop it? the reason I hesitate to simply drop it is that before I do drop, I placed the rollback tablespace offline. And there are errors during transaction since some tables somehow still checking on this tablespace. Can I simplely drop rollback tablespace, and Oracle would clean this internally, and everything would be finr?
thanks for your input.

Hi,
This is the steps to migration from rollback tablespace to undo tablespace (from 8i to 9i migration by manual upgrade) :
SQL>alter system set undo_management=auto scope=spfile;
SQL>create UNDO tablespace UNDOTBS datafile d:\database\mydb\system\undotbs01.dbf size 500M;
SQL>alter system set undo_tablespace= UNDOTBS scope=spfile;
SQL>shutdown immediate
SQL>startup
SQL>select SEGMENT_NAME,TABLESPACE_NAME,STATUS from dba_rollback_segs; --Verirify creation and usage UNDO tablespace
SQL>drop tablespace rbs including contents and datafiles;
SQL>create pfile=d:\database\mydb\system\pfile\init.ora from spfile;No need to drop old rollback segment.

Drop temporal tablespace

Hi all,
I'm working with an 11.2.0.1 RAC. I need resize the temp tablespace. In order to do it, I've created a new temp tablespace with the correct size and I've configure it as default tablespace for database. After it, I try to drop the old temp tablespace but when I launch the drop sentence, it never finish.
I've take a look and I can see some inactive sessions are using the old temp tablespace.
How can I drop it? Any ideas?
Best Regards,
dbajug

>
I'm not getting errors if I try to drop the tablespace. I execute this estatement:
ALTER DATABASE DEFAULT TEMPORARY TABLESPACE TEMP1;
DROP TABLESPACE TEMP INCLUDING CONTENTS AND DATAFILES;
But it never ends. No error appears. After 20 minutes, I cancel the execution with a Ctrl+C.
>
Because there are sessions which still use space in old temporary tablespace .I don't think this sessions which already used old space in old temporary tablespace) can automaticly change from old t new .hence you have to choose one of the above ways

Droping old tablespace after upgrade

Hi All,
I have finished upgrading ERP6 from ERP5.
In guide it asks to drop the old tablespace.
I have a tablespace PSAP<SID>640 which is showing 0% used.
There is new tablespace PSAP<SID>700 has been added there and it is filled
So when I was trying to drop the tablespace throught BRSPACE, it gives error that the tablespace contains 690 segments. And to use "force" option to drop it.
Now I want to know if we have to drop that tablespace and if yes then should I use the force option or can i do something about those 690 segments?
I would really appreciate your help.

Viewing Tables/data from an old tablespace

I'm using a database Oracle 11g.
I have a DBF file of an old tablespace from a different database that I want to connect to the existing database.
I've created a tablespace with REUSE caluse, and it was created successfully
SQL> create tablespace TEST datafile 'C:\DATA.DBF' reuse;
How can I view the tables/data within that tablespace?
Was that the right approach ?
Or should I attach that tablespace in a different way ?
Thanks in advance for your answers,
Roni

Hi JGarry,
I do not agree to your statement
"In addition to what the others said, understand that the metadata that describes what is in the tablespace is in the data dictionary in the system tablespace. If you have the system tablespace also, you may be able to construct a database that you can transport your data tablespace from. "
System table space will contains the metadata information about the table space, But it will not keep information about the segments of table space. So user will not be able to see the contents of table space.
Yes your point regarding proper backup and export is valid but can you elaborate more how to data recovery will the done in this user scenario.
Any ideas are welcome....
cheers

Why I got error ORA-02429 when I tried to drop a tablespace?

I use the following command to drop the tablespace:
drop tablespace users including contents and datafiles;The error message is below:
Error report:
SQL Error: ORA-00604: error occurred at recursive SQL level 1
ORA-02429: cannot drop index used for enforcement of unique/primary key

*Cause: An error occurred while processing a recursive SQL statement
 (a statement applying to internal dictionary tables).
*Action: If the situation described in the next error on the stack
 can be corrected, do so; otherwise contact Oracle Support.However, I have removed all the tables and indexes in this tablespace.
Nothing found when I issued the following enquiries.
select index_name from user_indexes where TABLESPACE_NAME = 'USERS';
select table_name from user_tables where TABLESPACE_NAME = 'USERS';Is there anything I missed?
Thanks in advance.

=================================================
Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
Go to [url tahiti.oracle.com]tahiti.oracle.com.
Locate the link for your Oracle product and version, and click on it.
You are now at the entire documentation set for your selected Oracle product and version.
BOOKMARK THAT LOCATION
Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab (for 10.x) or the "Master Book List" link (for 11.x) you will find the complete documentation library.
Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
Do the same with the SQL Reference Manual.
Do the same with the Utilities manual.
You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
Then set yourself a plan to dig deeper.
- Read a chapter a day from the Concepts Manual.
- Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them (listed in your alert log) in the Reference Manual.
- Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
- When you have finished reading the Concepts Manual, do it again.
