How to coalesce RBS tablespace??

Hi,
I´m using a database 9.2.0.7 that is using RBS and not UNDO Tablespace.
This tablespace is full and i can´t empty this.
How can i do that? Empty this tablespace. No one is logged on this database, so this tablespace don´t have any transaction on this.
ORA-01562: failed to extend rollback segment number 34
ORA-01650: unable to extend rollback segment RBS1 by 128 in tablespace RBS
Tks,
Paulo.

Cross check your 10g init.ora parameter with Metalink doc id 216205.1 (This note/doc mentioned lots of parameters for performance) and make sure you have collected stats for 10g database. If you are using global temporary table in 10g then delete stats for global temporary table and lock stats like
ONLY for GLOBAL Temporary Table
analyze table scott.GTEMP delete statistics;
execute DBMS_STATS.Lock_Table_Stats(ownname=>'SCOTT', tabname=>'GTEMP');
Hope performance will improve drastically.

RBS Tablespace Issue

Hi All,
Greetings,
Oracle 8.0.6
SunSolaris
My Rollbacksegment Tablespace datafile size is 1640 MB
but the actual used space is 217 MB.
is there any way to compress the size of 1640MB
Please Help me in this
Thanks in Advance
Adil

Hi,
01628, 00000, "max # extents (%s) reached for rollback segment %s"
// *Cause: An attempt was made to extend a rollback segment that was
// already at the MAXEXTENTS value.
// *Action: If the value of the MAXEXTENTS storage parameter is less than
// the maximum allowed by the system, raise this value. => Alter your RBS and allow more than 121 extents to be created in this RBS.
Also i found that RBS tablespace is marked as PERMANENT.Yes, it's normal.
..it means the rollback data does not get flushed out periodically?No
Also Should this tablespace be temporary? No, this can't be
How can i counter this problem?Free advise: RTFM about Rollback Segments! Start here (8i doc) or read the Concepts book.

Can size of RBS tablespace be reduced?

Hi folks.
Hope this is the right forum for this question.
Anyway, we're running Oracle 8.1.6 Standard Edition on Win NT
4.0. A few months ago, we ran a SQL Update statement on a table
with 176,000 rows and then did a Commit. As a result our RBS
(rollback?) tablespace grew quite large. Also, as a result, we
now do more frequent Commits. Anyway, my question is: can we
reduce the size of the RBS tablespace and if so how? I tried to
do it using DBA Studio but it wouldn't let me. Do I first have
to remove some Rollback Segments? (We have 6 now, each one 8,192
KB in size.)
Any hints, suggestions, etc. would be appreciated.
Thanks.

Hello Craig
To reduce the size of rollback segment you may issue the
following statement :
alter rollback segment <Segment-Name> shrink to <integer> K ;
If you have given the Optimal value for the specified Rollback
segment, you can shrink it to Optimal value as :
alter rollback segment <Segment-Name> shrink ;
Hope it will help you.

RBS tablespace abnormal growth

I am checking the tablespace size , i am seeing growht of RBS tablespace / it increases 297 MB in one day...Can any body tell me what is the reason & how i can solve that?

As you wish. You can put the other datafile to another disk. Oracle will stripe the data auomatically. Or you can enlarge your existing datafile if you don't have another disk to use.
Less datafiles means less administration effort. So you should trade off if it's worth to add a second or third datafile to your TEMP Tablespace. But more performance will perhaps also increase your salary ;-)

How to deal with tablespaces in Oracle XE (10g)

Hi,
First want to say I'm not a DBA so my knowledge on how to work with tablespaces is very limited. I built an application in Apex 3.2.1 on Oracle XE 10g and today for the first time I received this error when trying to save information to the database:
ORA-01691: Unable to extend lob segment by .... for table space FLOW....
What is the best way to deal with this? For now, after doing some google searching, I set my tablespace to AUTOEXTEND (it had reached about 500MB which was its max size). Is this the correct way to deal with this situation? Or should I create a new tablespace? I've never changed any of the default settings/tablespaces that came with the Apex/Oracle XE installation.
Any advice would be greatly appreciated....
Thanks,
Francois

ORA-01691: Unable to extend lob segment by .... for table space FLOW....
It seem related to tablespace is full and not able to extend more due to low hdd space or autoextend off or xe datasize limit(4g) reached!!!!
SELECT sum(BYTES/1024)/1024 AS SIZE_IN_MB FROM DBA_DATA_FILES;
SIZE_IN_MB must not be more then 4gb
If SIZE_IN_MB is less then 4g then check that Autoextend is off or on.
I hope this help

How to see the tablespace size

hi
how to get the tablespace size??
thx

Hello,
select SUM(bytes)/1024/1024 MB from dba_data_files
where tablespace_name = 'xxxxxx';
works fine.
I am trying to build a function for that:
select SUM(bytes)/1024/1024 MB
from dba_data_files
where tablespace_name=upper('&user')
However, I need to make some enhancements:
1. how to make comments in sql files?Refer to the REM statement in the sqlplus reference manual
2. a lot of outputs are generated:
SQL> @get_size
Enter value for user: tts1
old 3: where tablespace_name=upper('&user')
new 3: where tablespace_name=upper('tts1')
MB
2048
how to avoid that so that only the size is
displayed.
for example:
SQL> @get_size
Enter value for user: tts1
MB
2048
Refer to set verify off in the sqlplus reference manual.
>
3. how to let the function accept a parameter such
as:
SQL> @get_size tts1
Refer to the define command in the sqlplus reference manual.
>
4. how to include a usage (help) to that function
such as:
SQL> @get_size
usage: get_size <tablespace name>
Many thanksRefer to the prompt statement in the sqlplus reference manual.

How to rollback RBS and what happens to existing data

Let's say I am using Remote Blog Storage (RBS) in one of my content database and I decide not to use anymore.
1. How can I roll back RBS?
2. What will happen to my data and how can I migrate it from RBS to how SharePoint/SQL Server stores it normally in database?

There's a few blogs around with steps such as this one:
https://alipka.wordpress.com/2010/06/19/how-to-disable-rbs-in-sharepoint-2010/
I'd tackle it in several steps.
Make sure that no new content is being externalised
Move existing content back into the database
Remove old connections
Or i'd just try doing backup and restore operations for site collections to clean databases that don't have the RBS configured.

How SMON coalesces free space in oracle 9i and 10g

how SMON coalesces free space in oracle 9i and 10g?
Is it doing same as it was behaving in oracle 7 like looking through free extent table every five minutes (sys.fet$) to see if there are any adjacent free extents that can be coalesced into a single extent, and on every 25th cycle (i.e. every two hours and five minutes) it looks at the segment table (sys.seg$) to see if there are any temporary segments that need to be eliminated, as explained by jonathan lewis?
what are extent and segment tables available in oracle 9i and 10g like sys.fet$ and sys.seg$ in oracle7?

How i can change tablespace of a table in oracle 8.04

ORA-14004: missing PARTITION keyword
how i can change tablespace of a table

Hi,
It seems that the move tablespace feature is available on 8.1 or higher versions of Oracle. In your case you can try one of the foll....
Option 1:
Step 1:CREATE TABLE T1
TABLESPACE NEWTBS
AS(SELECT * FROM T);
Step 2: Rename or Drop the old table.
Step 3: Rename the new table to the old table name.
Option 2:
Step 1: Export the old table.
Step 2: Rename or Drop the old table.
Step 3: Create the table in the new tablespace. You may use the INDEXFILE from the imp command here.
Step 4: Import the old table and use IGNORE=Y

How to monitor temp tablespace

I server in 11gR2 and 10gR2.
Is there a way to monitor its usage, like, who is using it, how much space a session is using, what are the objects crated, ie. temp tables.
Thanks.

Hi
This might helpful

How to Shrink UNDO Tablespace

Hello,
We had a UNDO Tablespace of 22Gb but it is using just 2GB. How to shrink undo tablespace. we are using clustered 3 node production database 10.2.0.4
Is there is way that we can shrink UNDO Tablespace or do i need to create a UNDO tablespace and assign the undo tablespace to DB and drop the old UNDO?
How to ensure that transactions are done and free to drop the old UNDO?
Is it something we need to restart all the three nodes as each node has its own UNDO Tablespace.
Need Help on this issue.
would appreciate your quick response.
Thanks

if i am in your place i will do the following:
<pre class="jive-pre">1-Query DBA_DATA_FILES to determine the name of the datafiles of the UNDO</pre>
2. Create a new UNDO tablespace.
<pre class="jive-pre">CREATE UNDO TABLESPACE undo_ts2 DATAFILE '/directory/undo_ts2_01.dbf' SIZE xxxM;</pre>
3. Modify the database parameter to use the new UNDO tablespace.
<pre class="jive-pre"> ALTER SYSTEM SET undo_tablespace=undo_ts2 SCOPE=BOTH; </pre>
4-The Drawback:
<pre class="jive-pre">New transactions will begin using the new undo tablespace. After some time passes (at least the number of seconds specified by the UNDO_RETENTION initialization parameter), you can drop the old UNDO tablespace. The downside to this approach is that for a short time period, your database will have two UNDO tablespaces</pre>

How to estimate undo tablespace size in 11g?

I found someone document said, use this sql to estimate undo tablespace:
select (UR*(UPS*DBS))+(DBS*24) as "bytes" from (select value as UR from v$parameter where name='undo_retention'),(select (sum(undoblks)/sum(((end_time-begin_time)*86400))) as UPS from v$undostat),(select value as DBS from v$parameter where name='db_block_size');
but in my 11g database, the "select value as UR from v$parameter where name='undo_retention'" is 0. so above sql is always get 196608(8192*24)
How to estimate undo tablespace size in 11g?
Thanks very much!

for undo segments size you should turn it to be autoextend on as well undo management set to be AUTO
i.e
undo_managment='AUTO'
for retention see that link
Ora-01555, snapshot too old: rollback segment number 2 with name "_SYSSMU1
BTW as hemant stated leave it to be auto which is good approach but make sure enough space on disk has been
dedicated for undo segments are allowed to grow to the size they need to be based on the requested undo_retention.
