Server Administration :: Find Or Set New Oracle Instance Name On Backup Server

Sep 22, 2010

We performed image copy of production Oracle server (OS and instances) to a backup server. After a few weeks, we try to restore a latest Oracle database backup from production server to backup server. As we know, Oracle instance must be unique on the network.

Even we log on to backup server and bring up the instance, I think that still point to production instance since all init file, TNSNAMES.ora and listener file are still same. If we restore the database, we will end up bring down the production instance and restore on top of productions. How to change instance name on backup server including TNSNAMES, sqlnet, listener files in order for us to restore Oracle database from production to backup server?

Server Administration :: Unable To Find Server Process In Oracle Database For Specific Application / Client

Feb 13, 2013

I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.

1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?

SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID,
SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM,
SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID
FROM
SYS.GV_$PROCESS, SYS.GV_$SESSION
WHERE
SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST'
and SYS.GV_$SESSION.MACHINE like '%hostname%'

Server Administration :: How To Get Disk List On Any DB Instance That Uses ASM Instance

Mar 16, 2011

My context on our servers is the following one:

- one ASM instance
- X DB instances
- each DB instance uses 2 or more dedicated diskgroups from the ASM instance
- there is one diskgroup named FREEDISK that contains spare disks

On each DB instance you can see:

- the list and global parameters of all diskgroups using v$asm_diskgroup view
- the list and parameters of all disks the instance is using with v$asm_disk view

So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?

Server Administration :: Instance Name On Imaged Server?

Sep 22, 2010

We imaged production Oracle Server ( OS and Oracle and everything) to a backup server. I guess my question shall be how do we access the local instance via this backup server. When we log on to this backup server, we ran sqlplus and connected to the instance but it ended up to connect to production instance. Shall we stopped local Oracle services and change init.ora, tnsname, or listener files in order not conflict with production instance?

Server Administration :: Oracle RMAN Backup

May 10, 2012

My production database is about 900 GB in size but the actual data in our database is only approx 600Gb it means 300GB is a deleted data and not fragmented, as per my understanding the best way to resolve fragmentation is Import/Export but we can go for this option because its a very time taking process.

We are taking full database backup using RMAN every week and also going to upgrade our production database from Oracle SE to Oracle EE edition using the same full database RMAN backup, as i know Rman is also not backup of those blocks which not containing any data , it means if we will use Rman full backup to setup our new EE database it will only 600GB of data not 900GB or there is only Export/Import to remove fragmentation.

Server Administration :: ASM Instance Did Not Access Raw Devices

Sep 28, 2011

I've to install Oracle 10g on Solaris 10, Sparc. I prepared anything successfully, but, when I gone to create ASM instance, I found the Create new bow did not show any disks into. I take brief something:

1- Sparc & disks preparation:

# isainfo
sparcv9 sparc
# ls -lL /dev/rdsk/c4t50060E800570B715d0s6
crw-rw---- 1 root sys 336, 14 Sep 28 14:08 /dev/rdsk/c4t50060E800570B715d0s6
# ls -lL /dev/rdsk/c4t50060E800570B715d2s6
crw-r----- 1 root sys 336, 62 Sep 28 14:09 /dev/rdsk/c4t50060E800570B715d2s6
# ls -lL /dev/rdsk/c4t50060E800570B715d3s6

[code]....

Those 6 partitions disks above were supplied to ASM, so, I make mknod to link them.

# ls -lrt /asmdisks
total 0
crw-r--r-- 1 oracle dba 336, 110 Sep 28 15:35 disk6
crw-r--r-- 1 oracle dba 336, 94 Sep 28 15:39 disk5
crw-r--r-- 1 oracle dba 336, 78 Sep 28 15:39 disk4
crw-r--r-- 1 oracle dba 336, 30 Sep 28 15:39 disk3
crw-r--r-- 1 oracle dba 336, 14 Sep 28 15:39 disk2
crw-r--r-- 1 oracle dba 336, 62 Sep 28 15:39 disk1

Well, I go to ASM, but And nothing on Available Disk Groups.

Server Administration :: Organize Or Group Schemas Inside Instance?

Jul 8, 2011

I have a lot of shemas inside an instance... How to organize them?

What I see is a long list of schemas which could be difficult to manage if number of schemas grows up... For example, I'd like to group Schema_1, Schema_2 and Schema_3 in something like Group_1, so it could be seen more organized.

Group_1
Schema_1
Schema_2
Schema_3

Sometimes a java or .net application uses 3 or 4 schemas... these schemas are in the same instance which has other schemas for other applications.

Server Administration :: Creating ASM Instance Using DBCA / ORA-01012 Not Logged On

Jul 14, 2010

create an ASM (Automatic Storage Management) instance using dbca. At first try I mistakenly skipped the part where I click on ASM Parameters to add /dev/raw/raw* as my asm_diskstring so it created an ASM instance. When I get to the next page ASM Disk Groups, I selected Create New and I did not have the desired display, because of the step I missed.

I went back to do some cleaning up as follows:

1) Edit the oratab file to remove the ASM entry

2) backed up these files by renaming to old-<filename>
old-ab_+ASM.dat
old-hc_+ASM.dat
old-lk+ASM
old-orapw+ASM
old-spfile2+ASM.ora

3) killed the following processes (kill -9):

oracle 1590 1 0 22:52 ? 00:00:00 asm_pmon_+ASM
oracle 1592 1 0 22:52 ? 00:00:00 asm_psp0_+ASM
oracle 1594 1 0 22:52 ? 00:00:00 asm_mman_+ASM
oracle 1596 1 0 22:52 ? 00:00:00 asm_dbw0_+ASM
oracle 1598 1 0 22:52 ? 00:00:00 asm_lgwr_+ASM

[code]....

4) Run the following as root:

/u01/app/oracle/product/10.2.0/db_1/bin/localconfig delete

5) Restarted the database

Now when I try to go through the steps to create an ASM instance, at the point after I enter my ASM Parameters, I get the following prompt:

"DBCA will now create and start the ASM instance. After the ASM instance is started you can create the diskgroups to be used as storage for your database."

I click OK. Then I get the error message:

ORA-01012 not logged on
