Single tablespace or full database in 10g

Hi,
Which is the best regarding performance...what ever it may be...when doing hot backup...which is the best in all ways..
(a) putting single tablespace in backup mode and copying
or
(b) Putting total database in Backup mode and copying...
can anybody sched some light on this..in all ways..

The best is to stop using paleolithic backup techniques and use RMAN with Block Change Tracking.

Restore a single tablespace from full backup erroring out

Hi,
I have backed up the full database using RMAN:
$ rman catalog rman/rman@catdb target /
RMAN> run {
backup as compressed backupset
format '<Full Path>/databkp/DATA_%d_%s_%p'
database
plus archivelog format '<Full Path>/arcbkp/ARC_%d_%s_%p';
Backup was successful.
Now dropped the tablespaces:

I think you misunderstand some concepts.
1) drop tablespace RTESTUSR including contents and datafiles;
is a valid command, it removes the named tablespace from the database. There's nothing wrong with the database (although it may be a logical (human) error). Restore/recovery is used to repair media failures. RMAN is right: 'RMAN-06019: could not translate tablespace name "RTESTUSR"', since there's no such tablespace in the actual database, the restore/recover process fails.
2) Unfortunately you hide your database version. Up to 10gR2 tablespace point-in-time recovery cannot be used to recover dropped tablespaces, in 11gR1 and higher it's possible.
And - TSPITR - requires a little bit more than 'set until ...'. Refer to the doumentation for your unknown database version.

How to replicate full database in 10g

Hi,
We have 9i database but soon we will be migrating to 10gR2. I want to see are there any other options in 10g to replicate full database other than data guard. I want to use that replicated database when ever primary database is not available due to network or other issues.
Thanks!

I'm not sure I follow. A database is either in ARCHIVELOG mode or it isn't. That's not a table-level setting. Are you saying that you do unlogged operations into a subset of tables on a regular basis?
If so, does that mean that this is a data warehouse/ data mart and not an OLTP system? Could you rebuild the standby once a day, say, after the batch load and fail over to that point-in-time system? Or are there ongoing transactions that need to be replicated?

Restore a single table from full database backup

Hi,
I have a full database (10.2.0.1) backup with RMAN.
Suddenly a table got truncated. How to get back that table without restoring and recovering the full database (Point in time recovery) since if I restore the database to an earlier time then the other transactions will hamper.
Also creating a standby database and import export the table will solve my problem. But is there any other way to restore the lost table.
Thanks in advance.

No other way to restore the data if you don't want do point in time recovery. If you drop the table then you can restore it from the recyclebin but for the truncate operation it won't help. If you have enabled the flash back table for that particular table then you can restore the data for only that table.

Full database exp/imp between RAC and single database

Hi Experts,
we have a RAC database oracle 10GR2 with 4 node in linux. i try to duplicate rac database into single instance window database.
there are same version both database. during importing, I need to create 4 undo tablespace to keep imp processing.
How to keep one undo tablespace in single instance database?

JIm,
I also want to know can we add the exclude=tablespace on the impdp command for full database exp/imp?You can't use exclude=tablespace on exp/imp. It is for datapump expdp/impdp only.
I am very insteresting in your recommadition.
But for a full database impdp, how to exclude a table during full database imp? May I have a example for this case?
I used a expdp for full database exp. but I got a exp error in expdp log as ORA-31679: Table data object "SALE"."TOAD_PLAN_TABLE" has long columns, and longs can not >be loaded/unloaded using a network linkHaving long columns in a table means that it can't be exported/imported over a network link. To exclude this, you can use the exclude expression:
expdp user/password exclude=TABLE:"= 'SALES'" ...
This will exclude all tables named sales. If you have that table in schema scott and then in schema blake, it will exclude both of them. The error that you are getting is not a fatal error, but that table will not be exported/imported.
the final message as
Master table "SYSTEM"."SYS_EXPORT_FULL_01" successfully loaded/unloaded
Dump file set for SYSTEM.SYS_EXPORT_FULL_01 is:
F:\ORACLEBACKUP\SALEFULL091113.DMP
Job "SYSTEM"."SYS_EXPORT_FULL_01" completed with 1 error(s) at 16:50:26Yes, the fact that it did not export one table does not make the job fail, it will continue on exporting all other objects.
. I drop database that gerenated a expdp dump file.
and recreate blank database and then impdp again.
But I got lots of error as
ORA-39151: Table "SYSMAN"."MGMT_ARU_OUI_COMPONENTS" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
ORA-39151: Table "SYSMAN"."MGMT_BUG_ADVISORY" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
......ORA-31684: Object type TYPE_BODY:"SYSMAN"."MGMT_THRESHOLD" already exists
ORA-39111: Dependent object type TRIGGER:"SYSMAN"."SEV_ANNOTATION_INSERT_TR" skipped, base object type VIEW:"SYSMAN"."MGMT_SEVERITY_ANNOTATION" >already exists
and last line as
Job "SYSTEM"."SYS_IMPORT_FULL_01" completed with 2581 error(s) at 11:54:57Yes, even though you think you have an empty database, if you have installed any apps or anything, it may create tables that could exist in your dumpfile. If you know that you want the tables from the dumpfile and not the existing ones in the database, then you can use this on the impdp command:
impdp user/password table_exists_action=replace ...
If a table that is being imported exists, DataPump will detect this, drop the table, then create the table. Then all of the dependent objects will be created. If you don't then the table and all of it's dependent objects will be skipped, (which is the default).
There are 4 options with table_exists_action
replace - I described above
skip - default, means skip the table and dependent objects like indexes, index statistics, table statistics, etc
append - keep the existing table and append the data to it, but skip dependent objects
truncate - truncate the existing table and add the data from the dumpfile, but skip dependent objects.
Hope this helps.

Can we create new tablespace in Oracle Database 10g Express Edition?

Hi,
Can we create new tablespace in Oracle Database 10g Express Edition instead of using the default "users" tablespace provided?
Please advise.
Thank you.

Correct. The sum of all user tablespaces is not allowed to exceed 4 GIG.
You could try shrinking your tablespaces. Theres a script called maxshrink on http://asktom.oracle.com which is useful for this.
You could compress your tables.
If you are storing lobs, you could consider storing them as bfiles.
Or upgrade to Oracle Standard Edition 1. Its not that expensive.

TEMP tablespace getting full while inserting a CLOB in Trigger

We have a Oracle 10g (10.2.0.4.0) DB on a Solaris 9 box which also runs our J2EE web-service application on Weblogic 8sp6 server.
We get around 220K web-service requests from upstream callers daily to insert data in the main table, say TABLE1, which has daily partitions on a date column. This table has around 21 columns out of which 1 is a CLOB column.
Now this table has an AFTER INSERT trigger which calls a package procedure to insert the same record into another table, say TABLE2.
From Java application insert statement in executed in below format using a weblogic jdbc connection pool :
INSERT INTO TABLE1(COLUMN1, COLUMN2, ........., CLOB_COLUMN,........, COLUMN21) VALUES (:1, :2, :3, :4, :5, :6, :7, :8, :9, :10, :11, :12, :13, :14, :15, :16, :17, :18, :19, :20);
Clob object is prepared in application using ojdbc14.jar.
We are observing a strange issue here. The TEMP tablespace utilization keeps on growing as more and more inserts are executed by application and after ~125K inserts the TEMP tablespace gets full and we start getting ORA-01652 error.
On further analysis we could see that there are only 7-10 session being maintained but as more and more inserts happen TEMP tablespace utilization goes on increasing for each of these sessions.
When we tried with inserting just few records and then watching the session details in v$session_wait then we could see that it is in INACTIVE state and waiting for the event ‘SQL*Net message from client’. This does not seem correct as the session has successfully inserted the data and committed the transaction and we can see the data in the tables as well.
The confusing thing here is when we modify the trigger to pass blank string('' ) instead of the CLOB column to TABLE2 then this issue does not occur. All 200K records are inserted properly and TEMP tablespace utilization also keep always below 1%.
Can you please help us in solving this issue. Is this related to any oracle issue?
Inside the package we have tried using DBMS_COPY statement to copy the CLOB column after insert but still same result.
Code for reference:

=====================================

My first thought on reading your post is that not only are you using a database version that is now so old it is in extended support and even then not even the most recent patchset for it.
The first thing I would do is move to 11gR2 and if you can't do that at least get to 10.2.0.5 and apply CLOB relevant patches as well.
Same goes for your operating system. Solaris 9 is ancient: So move to 10 which has vastly improved memory management.
To help you further it would be really valuable to know the table layout. For example is this a heap table or an IOT? Is it partitioned? Is this RAC? What size are the CLOBs? Are they stored in-line? Chunk size? etc.
This page should start you down the right road:
http://docs.oracle.com/cd/B19306_01/appdev.102/b14249/adlob_tables.htm#sthref204
But I am also wondering why you would use a trigger to, as you say, "insert the same record into another table." This description is a poster child for "bad design."

What are the things to check after full imp in 10g?Only public database links which are in use by your these users which you export/import (Only if you did user level export/import and not DB level).
If you log files does not show error during creation of any object, you don't need to double check any thing. Otherwise do on with the method which you mentioned by counting the objects.
Or you can create a database link from source to destination and use a query with MINUS to find out if there is any object missing
select object_name,object_type from user_objects
MINUS
select object_name,object_type from user_objects@destination_database;Salman

plz reply me appropriate solution.
thanks.

Possibly bug 3386590 (4021: TIMEOUT OCCURRED WHILE WAITING TO LOCK OBJECT), upgrade to 10gR2 or even better 11gR2.

Full database Export

Hi
We are having a database 10g running on solaris OS. We are getting a new server and I need to move the data. This is what I am planning to do.
Take full database export from original server. (This includes tablespaces, all schemas and data)
Import in new server, from SYS schema once Oracle is installed. so all the schemas and objects are imported.
Can you let me know this approach is right any precautions to be taken?
Thanks

Use of backing up a single tablespace or datafile

Hello,
I am reading the RMAN manual and I'm quite familiar with backup up a tablespace or datafile, but I can find very few uses for that. Backup up a tablespace is useful for TPITR, but since that needs another instance its of very little use in most production environments. I think you cannot restore an old version of tablespace in a normal database, unless the tablespace has long been made read-only, in which case RMAN's optimizations will do the trick.
Even less use I can find for datafile backup. I have absolutely no idea what you can do with a single datafile.
Can you please clarify me on the uses of these RMAN features?
Thank you.

Dear Albi!
Think of the following scenario:
You have a very large (let's say 1 Terabyte) production database that is split into n tablespaces. This database is in archivelog mode and a full backup of the hole database would take more than 10 hours.
scenario end.
In such a scenario I think you will not take a full database backup very often. Therfore you can backup portions (tablespaces and datafiles) of your database. This will take less time then a hole DBbackup.
If you have to restore your DB then RMAN will take all the files it needs from all your backup. RMAN uses always the most actual version of your datafiles. After the restore RMAN will take the archivelogs to recover all datafiles to the most actual point in time. And that's the point why partial backups of your db are not only usefull for TSPITR.
I hope I could make clear what the operative point is with partial backups.
Yours sincerely
Florian W.
