RMAN Restore query

Hi Gurus,

I have a question regarding RMAN. I have setup the recovery window of 2 days and i ran the command delete obsolete to remove the backup files physically as well as from catalog.

Backup for the previous month was taken on tape and now i want to restore the previous month backup using RMAN.My question is since i removed the backup using "Delete Obsolete" would i be able to restore using RMAN (with catalog) as RMAN wouldnt be able to find the entry about the previous month backup in the recovery catalog after i used "Delete Obsolete".

Select a minimum from a table but only if it occurs after a date

Tue, 09 Mar 2010 15:49:00 GMT

Select a minimum from a table but only if it occurs after a date

Let us say I have a table with the following

identifier varchar2(8);

ident_ext number;  // This number increases for each transaction

trans_type char(2);

trans_date date;

I have a fairly complex query....well for me it is complex...but it is the base set that is giving me problems.

The rest of my query is based on the fact that particular transactions occured after the first occurance of a transaction of type 'L'.  

I need this first 'L' to have occured within 24 hours of 0200.  If there were transactions of type 'L' that occurred before that time then it does not matter what occured within the 24 hour time frame they should not be counted.  So if transaction XYZ has a transaction of type 'L' that occured 3 days ago it would not be a part of the set...even if it has a transaction of type 'L' that occured at 01:00 today.

So basically I want a proficient query to return the first transaction of type 'L' as long as that transaction occured within 24 hours of 2:00am today.

What I have is belo...

Database is slow

Tue, 09 Mar 2010 11:41:33 GMT

Database is slow

Hello All,

I have one performance problem with me.

Users are complaining that the database is slow.I observed that even a single sql statement like "select event_name from dm_audittrail_s" is damm slow.It took around 45 min to display the results and this table consists of around 1 million records.It's a documentum application.

We have recently upgraded the database from 10.2.0.4 to 11.1.0.7.

I observed that for most of the sql statements,the wait event is "db file sequential read" in trace file.

Also the top wait events in awr report are direct path read and db file sequential read.

the %iowait was in the range of 95 in ash report for the period.

All the datafiles are on same drive on windows system.

Is it an indication for I/O problem?..can anyone suggest the ways to improve performance?

ORA-01555 on full export

Tue, 09 Mar 2010 09:00:34 GMT

ORA-01555 on full export

Hi all,

Since a few days, I have the following problem...

Every night, a full export is performed on a database. We get systematically an ORA-01555 error on the export of a table in particular (this table 's size is 112 Mbytes, and it contents a CLOB field, I don't know if it is important).

The workaround in such cases consists in extending the UNDO tablespace and increasing undo_retention.

But after many attemps (UNDO is extended to 800 Mbytes, undo_retention is set to 3600), the problem still occurs.

What else can I do ?

Thank you very much.

I can't see you table

Mon, 08 Mar 2010 20:15:33 GMT

I can't see you table 

In doing an Ingres to oracle database conversion, ingres offers a lock that prevents anyone from seeing the data before you make and while you make your changes.  Can oracle do the same ?  

They don't want users querying data that is about to be changed or is in the process of being changed.   If two users login and one changes it,  they don't want the 2nd user to see old data,  that has just been changed.

I know that You Use Lock Table Comman

If you want exculsive lock you dont want any body else accessing  the data you can use 

LOCK TABLE Emp_tab IN ROW EXCLUSIVE MODE; 

this will not allow DML .   BUT I believe that they can still see the data.   

Has anyone had this requirement and how do you 

get around it ?

Thanks.

delayed block cleanout

Mon, 08 Mar 2010 13:04:16 GMT

delayed block cleanout

Hi all,

Can you verify my understanding regarding delayed block clean out?

As i have understand it:

Interested Transcation List

Interested Transaction List is a small portion in the data block header which stores the list of all the transcations happening in the database.

It specifically contains the following things:

1)A transaction ID[XID].

2)An Undo Byte Address[UBA].

3)A flag bit.

4)Count of rows locked by that transaction. 

5)An SCN

When ever any DML takes place, the relative rows are locked and hence the ITL entry is filled with these informations mentioned above,

1)A unique transaction ID is allotted to identify that transaction

2)UBA points to the location of the UNDO block in the undo tablespace 

  where undo information of the transcation is stored.

3)A flag bit is set to show that the row is locked.

4)If the transaction modifies 3 rows,then 3 is set as 3 rows are locked.

5)SCN of the last full block cleanout

When a user commits, following things happen:

CPU Usage in Oracle 9i Statspack

Fri, 05 Mar 2010 19:41:08 GMT

CPU Usage in Oracle 9i Statspack

I am seeing some strange CPU usage numbers in the hourly Statspack reports I run for a particular database.  E.g. in one period Statspack reported 699K seconds of CPU usage although the machine's capacity (24 CPUs)would allow 86,400 seconds max.  The recent change is that the Apps folks have been executing some long-running and CPU-intensive packages.  After thinking about it I am wondering if Statspack does not see the CPU usage for these packages until they complete execution.  I've opened an S/R with Oracle Support but so far they have not confirmed that.  As a precaution I dropped and reinstalled Statspack by I'm still seeing this phenomenon.

Right now what we have is one node taking all requests while other node is just sitting as standby. It would great if we have somebody done this load balancing before so that he/she can give us valuable tips.

CRS failover problem

CRS failover problem

I have IBM AIX HACMP 6 cluster with 10.2.0.4 CRS RAC on it.

In a test scenario if we bring down the enthernet card of Node 1 (used for cluster interconnect), both instance hang.

In other case if we bring down the IP from node 2, then only instance 2 hangs.

Hence in any case the failover scenarios try to keep instance 1 of RAC up.

Can some one provide reason for this
