Databases:ASM ratio

I have 7 production databases (all 11g) siting on a 3 node Linux cluster and all making use of two ASM disk groups DATA and FLASH. The databases range in size from 5GB to 60GB, and I have 200GB of primary storage in each disk group, of which I have currently 50GB free on each disk group.
Thinking ahead if I had ASM instance failure, this would obviously bring down all my databases which is a concern to me.
If presented with the same scenario, would it be preferable to setup a separate ASM instance per database, or considering that the complexity of an ASM instance is more straight-forward that for a database instance - am I in relatively safe ground with the one ASM instance?

Hello
Platform AIX 5 TL8,
Oracle 10.2.0.4
Context RAC ASM (2 nodes)
We have 25 Oracle databases working under the same ASM Instance on our RAC. I think that this is too much and split at least by creating a new ASM instance on another RAC environment should be better.
Hi Den ,
It is not advisable to have 25 databases in single RAC . Instead of databases , you can also think of creating different schemas in same database.

RMAN restore from active database, ASM

I'm attempting to refresh a stage database from a prod database using RMAN restore from active database. Both are on ASM. After working through various hurdles, I've got one issue I'm a bit stuck on. I've got a handful of data files that do NOT have OMF names (ie MSTRDATA/mstrmdpd/datafile/gsa_indx instead of MSTRDATA/mstrmdpd/datafile/gsa_indx.351.714779777) and these are failing when I do the restore. The syntax I'm using in RMAN is as follows:
duplicate target database to dwstage
from active database
spfile parameter_value_convert 'dwprod','dwstage'
SET DB_FILE_NAME_CONVERT '+DWPROD','+DWSTAGE'
SET LOG_FILE_NAME_CONVERT '+DWPROD','+DWSTAGE';
The error message I'm getting is this:
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 04/21/2011 13:26:24
ORA-17628: Oracle error 19505 returned by remote Oracle server
continuing other job steps, job failed will not be re-run
Normally from what I've seen/read this error can be traced back to needing to pre-create the directories for the controlfiles etc, but since 90% of the datafiles copied correctly...
Any suggestions as to a way around this, or am I going to be forced to restore from a backupset?

This fails saying that "ORA-12528: TNS:listener: all appropriate instances are blocking new connections" which is quite normal given that the listener is havig a handle in BLOCKED state for this AUXDB as it is in NOMOUNT state.
Could you please help me on how to proceed?
One option can be to create the controlfile manually and mount the instance before doing the duplicate. I hope Rman can continue from there.
Another option is to go for backup based duplicate.
Is there any other way to go?
Provide static registration on AUXILIARY side for your auxiliary instance and try again.For example change listener.ora file as
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = AUXDB)
      (ORACLE_HOME = <your oracle home>)
      (SID_NAME = AUXDB)
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = <auxiliary host/ip>)(PORT = 1521))
)And restart listener on auxiliary host then try again

Standby Database ASM Disk Groups

Hi Guys
I wonder if anyone can tell me - does a standby database have to have an identical configuration for its ASM Disk Groups?
My production database has two disk groups, one for data and the other for temp. Can I get away with a single diskgroup in my standby database or would I need two of the same name as the production database?
Cheers
Simon

Hi Saml
I have been busy googling at the same time as discussing this and it would appear that it will use the db_file_name_convert:
http://asanga-pradeep.blogspot.com.au/2012/07/11gr2-standalone-data-guard-with-asm.html
The link above shows the output of someones RMAN session where the OMF names are changed automatically. Problem is that some people are recommending that the parameter not be used, so now I am really confused!
I think I will try the parameter, if it doesnt work or the duplicate fails I will drop the temp table space in production and then do the duplicate, then recreate the temp tablespace. I can do that because there will be no one on the system on Sunday when I do it.
Thanks again for your help - I will let you know how it goes.

Diagnosing an ASM space issue for a primary and a standby database instance with external redundancy.

I've received an alert from Enterprise manager saying "Disk Group DATA_SID requires rebalance because at least one disk
is low on space". My colleague who I would go to with this question is unavailable, so this is a learning opportunity
for me. So far google and Oracle documentation have provided lots of information, but nothing that answers my questions.
I've run the following query on both the primary and standby databases ASM instances:
select name, disk_number, sector_size,os_mb, total_mb, free_mb, redundancy from v$asm_disk;
On the primary I get 4810M Free space and 18431M Total Space
on the standby I get 1248M Free space and 18431M Total Space -- this is the one that complained via OEM
When I run the following query in the database instance:
select sum(bytes)/1024/1024 MB from dba_segments;
I get 3736.75M as a result.
My questions are:
1. Will OEM's suggestion to rebalance the disk actually help in this situation since the instance is set up with external redundancy?
2. If I've got 18G of space and only 3.7G of data, why is OEM complaining?
3. How can I reclaim what I presume is allocated but unused space in my problem disk group?
4. How can I determine what extra data the standby has that the primary doesn't since both have the same total space allocation, but different amounts of free space?

Thank you for the reply. That link is very good.
We are an 11.1 version of our database. Linus is OEL 5.6.
So, looking at the portion of the link that refers to 'Add Standby database and Instances to the OCR' - If we use SRVCTL to give the STANDBY the role of ‘physical_standby’ and the start option of ‘mount’, what effect will that have if the STANDBY becomes our PRIMARY?
Would these database settings need to be modified manually with SRVCTL each time?
We understand why the instance is not starting when the node is rebooted, we are looking for a best practice of how this is implemented.
Thank you.

E-business suite11i ASM database upgrade

Hi all,
In our environment we have E-business suite 11i (11.5.10.2) with ASM instance 10.2.03 on solaris 10. I need to upgrade just database ASM instance 10.2.0.3 to ASM instance 11gR1, Plz anyone provide me a right document.

Standalone server with ASM & database, oracle HAS service not auto start

WE have a standalone oracle and grid on linux redhat 5. Oracle version is 11gr2, and I noticed everytime server reboot, the d.bin processes are all gone and has services are not automatically rebooted during server reboot.
How to handle this issue?
Thanks in advance.

You said:
>
That's not what HAS is for. HAS will restore the services to the state they were if an incident happens that aborts a service. It will not startup your database/ASM when the server reboots. Thats what the famous dbora script is for.
>
Yes it is. Not only will ohasd try to restart failed resources, but it will also (unless disabled) start them in the proper order when the node boots.
I am sorry, but your statement is wrong.
From http://docs.oracle.com/cd/E11882_01/server.112/e25494/restart001.htm#ADMIN12709
>
Oracle Restart improves the availability of your Oracle database. When you install Oracle Restart, various Oracle components can be automatically restarted after a hardware or software failure or whenever your database host computer restarts.

I want to install RAC database (oracle 10g on RHEL5). Now we are configurind shared storage for the both servers (nodes). In disk configuration (SAN on EVA 4400) we have created the volume group for the disk to use for ASM and present the disk group to the servers. Actually when we check the server we cannot see the disk (shared storage).
[root@cdr-analysis01 ~]# ls /dev/cciss/ -lR
/dev/cciss/:
total 0
brw-r----- 1 root disk 104, 0 Jul 1 2009 c0d0
brw-r----- 1 root disk 104, 1 Jul 1 14:29 c0d0p1
brw-r----- 1 root disk 104, 2 Jul 1 14:29 c0d0p2
brw-r----- 1 root disk 104, 3 Jul 1 14:29 c0d0p3
brw-r----- 1 root disk 104, 4 Jul 1 2009 c0d0p4
brw-r----- 1 root disk 104, 5 Jul 1 14:29 c0d0p5
brw-r----- 1 root disk 104, 6 Jul 1 14:29 c0d0p6
brw-r----- 1 root disk 104, 7 Jul 1 2009 c0d0p7
brw-r----- 1 root disk 104, 8 Jul 1 14:29 c0d0p8
(they are local disks not the shared disk)
My questions are:
- How to mount the disk to be seen in the server
- How to configure the disk for ASM is there any document for this. In my knowledge the disk to use for ASM doesn't need to be formated with a file system and shouldn't see when we run the df command.
Does anybody can help me as it's very urgent for us.
Thank you

Hi all,
NOw the disk is presented to server. but my actual problem is how to create shared partition of this disk for the servers.
Our actual status is we have created one volume group with 500 Gb in the sun and this volume group is called vg_oradata. we will use this storage for OCR, voting disk and the databse file (ASM). A si know from documentation i have to create one shared partition for OCR, one shared partition for Voting disk and another for database.
That i want to do is creating for example :
ocr_partition (25 Gb) : for OCR
vote_partition (25 Gb): for Voting disk
oradata_part1 (150 Gb): for database (ASM)
oradata_part2 (150 Gb): for database (ASM)
oradata_part3 (150 Gb): for database (ASM)
My problem is how to create this partition because when i'm trying to create it from Logical Volume Manager of Linux i cannot find them in to servers.
I mean i'm new in system administrator and our SAN vendors also doesn't know how to it in LInux system.
Could you help me please if possible.
My system is Linux Red Hat Enterprise 5 and i'm going to use Oracle 1Og RAC.
Thank you

How to start Oracle 10g RAC database and clusterware?

I have steps to stop the 10g RAC Database and clusterware but not sure about starting it.
I have heard executing
$crsctl stop crs --as root
on each node
will start the database,asm,nodeapps .Is that true?
or we have to do that step by step like we do in stopping the clusterware and database below
1.Stop the agent:
cd to $AGENT_HOME/corpng04.amhc.amhealthways.net/bin, then run: ./emctl stop agent
2.Stop the full database
$ oracle_home/bin/srvctl stop database -d db_name
3.Stop the ASM Instances on node1,node2
$ oracle_home/bin/srvctl stop asm -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name
4.Stop the NodeApps :vip,listener,oms and gsd
$ oracle_home/bin/srvctl stop nodeapps -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name
5.Stop the CRS cluster processes :those bloody 3 evmd,ocssd,crsd
$su - root
$CRS_home/bin/crsctl stop crs

Paul R @ NL wrote:
before is shutting down crs i tend to stop the instances and services via srvctl then stop crs via crsctl
just the way i do it. not saying it's the right way but it is the one i am comfortable with.Good -) If we stop CRS, but forgot shutdown oracle instances ... we'll see shutdown abort in alert log file(that mean instances are shutdowned abort).
We should shutdown instance before stop CRS anyway.

Rolling upgrade in MAA database with 2 node RAC on each site

All,
I have 2 node rac on SITE A, and it has Physical Standby database on SITE B it also 2 node RAC. Currently it is on 10.2.0.4 on AIX systems. We have mission crictical application runing and we can't aford the downtime of 5 to 6 hr to upgrade our CRS,ASM,DB oracle homes to 11G or even 10.2.0.5. I read rolling upgrade document on metalink and also documnet as well, and come up with following sequence.
SITE A==Primary Site, SITE B == Standby database
1) Shutdown DB on SITE B
2) Take the OS Level Backup of Binaries only on SITE B (Both node), I think this is just a Precautionary Measure
3) Start the DB on SITE B Still Physical Standby database let it synch with primary Site SITE A
4) Convert SITE B to Logical standby database
5) let it run for some time and be the two site SYNCH
6) now stop archivelog shipping to STANDBY SITE SITE B
7) Shutdown SITE B and apply the patch/upgrade binaries (CRS/ASM/DB)
8) Start and upgrade the DB on SITE B
9) Start the logical standby apply (SQL APPLY) and let it catch up with SITE A
10) Now Switchover to logical standby database on SITE B and ask application to connect to SITE B
11) Make sure the archivelogs are moving from SITE B to SITE A and SQL Apply is runing.
12) Now Stop archive log flow from SITE B to SITE A
13) Stop the database/ASM/CRS on SITE A
14) upgrade the SITE A binaries (CRS/ASM/DB)
15) Start and upgrade the DB on SITE A
16) Start the logical standby apply (SQL APPLY) and let it catch up with SITE B
17) Now Switchover Back to SITE A and let the application connect to SITE A
At this point by SITE B is a Logical Standby database
I think these summaries the steps involved in rolling upgrade, but I can't understand how I can go back to my MAA with physical standby database mode?
Does anyone has done this? Can anyone give me some tips or comments on my steps??
Help me if you can... thanks in advance.

Hi,
Is it you want to know the OS/Kernel side setting? You must comply with the following kernel requirements to install the clusterware.

How to apply archive in Standby Database?

Hello,
My Database are running in linux plateform. I am seeing that archives which are generating are not copying to standby server & not applying.
Can anybody suggest me how to copy archive from primary database(ASM file system) to standby Database & apply those archives?
Thanks

Hi,
I am having similar problem. The primary logs are shipping on to standby but are not getting applied.
Here are the outputs:
From primary
SQL > select thread#,max(sequence#) from v$archived_log where archived='YES' group by thread#;
THREAD# MAX(SEQUENCE#)
1 27908
2 28476
3 31643
select max(sequence#) from gv$archived_log;
MAX(SEQUENCE#)
31643
From Standby
SQL > select thread#,max(sequence#) from v$archived_log where applied ='YES' group by thread#;
THREAD# MAX(SEQUENCE#)
1 26862
2 27580
3 30874
select max(sequence#) from v$archived_log;
MAX(SEQUENCE#)
31643
Any help is appreciated.
Thanks in advance.
