11.2 Single Instance DB with ASM

DB version:11.2.0.2
OS : RHEL 5
I want to create a single instance DB with ASM. I did a software only installation . In DBCA , i can't find an option to create Diskgroup through UI like we have in 10.2's DBCA. I will have to use ASMCA for this. But i think i'll have to install Grid Infrastructure for this. Is there alternative way of creating diskgroup through UI ?

Is there alternative way of creating diskgroup through UI ?You need to install first Grid Infrastructure with sotware only option to can use ASM
Than you need to use asmca to create asm diskgroup
Than you need to use install Oracle 11gR2 software only,than you can use dbca

Convert ASM single instance to RAC ASM instance...

Hi, all
Im installing OracleDatabase with RAC and I got an error on the Database Configuration Assistant that says "The ASM instance configured on the local node is a single instance. To manage this instance as a single-instance ASM restart DBCA and select the single instance database option. To manage this instance as RAC ASM, convert it to RAC ASM first".
How I can convert it??
Thanks

See the link below for converting a single instance ASM to RAC ASM. The link is to the Oracle® Database Oracle Clusterware and Oracle Real Application Clusters Installation Guide for Linux. If your platform is not Linux, check the Install Guide for your OS.

Single instance app with native packaging

Is there any way to allow only one instance of the app to run with javafx2 native packaging? Like an attribute in the build.xml or something?
I'm using the .exe for windows and the .dmg for mac.
Appreciate your help.

There is no simple deployment build switch that I know of for achieving a single instance app.
A couple of ideas (none of which I have tried).
Perhaps you could use the SingleInstanceService:
http://www.oracle.com/technetwork/articles/java/fxbest-1583679.html "Ensuring Only One Instance of the Application Is Started"
http://docs.oracle.com/javase/7/docs/technotes/guides/javaws/developersguide/examples.html#SingleInstanceService "SingleInstanceService"
It is a jnlp api based service though and I'm not sure if such a service would be available to a packaged app (maybe it would require including the jre/lib/javaws.jar file with your app or something like that).
You could write out a lock file when the app starts.
On unix (i.e. mac/linux) the lock could include the process pid for your app. On startup, check if there is a process with the lock pid currently running, if so, don't startup and perhaps send an interrupt signal to the existing app notifying it that the user tried to start a new instance.
On windows you could read and write the lock value value from the registry.
To get rid of the OS specific stuff surrounding this, perhaps this kind of lock logic could be implemented using the Java Preferences API:
http://docs.oracle.com/javase/7/docs/technotes/guides/preferences/index.html
Intellij Idea is open source and and seems to have this kind of functionality, so you could check how they do it.

Convert single instance to rac on 11gr2

Hi,
I have 11gr2 database single instance running with ASM storage attached. i want to convert it into RAC on same server.
Can I take RMAN backup and restore in RAC ORACLE_HOME ? or do I need to go with rconfig or other steps?
Please let me know if have any good doc.
thanks

here is detail:
DB server =db1
installed oracle binary for non-RAC-oracle 11gr2.

Migrating single instance SAP and Oracle 11.2.0.1 database to Oracle RAC

We have a single instance SAP Netweaver environment on Oracle 11.2.0.1 database and want to migrate to Oracle 11.2.0.1 RAC and ASM. The documents are for 11.2.0.2 and later but we want a way to:
1. Migrate single instance SAP and Oracle 11.2.0.1 instance to ASM
2. Configure the environment as four node Oracle 11.2.0.1 cluster
Thus far, I have:
1. Installed clusterware 11.2.0.1
2. Installed four ASM instances
My questions:
1. We want to migrate the single instance database to same server and extend to four node cluster and ASM
However, current SID for SAP and Oracle must remain the same. The problem I have is that the target database name needs to be same as source on same physical host.
2. How would I use RMAN to migrate the single instance database to ASM for 11.2.0.1?
3. How would I use rconfig after this step?

3- We have installed four node Oracle 11.2.0.1 clusterware on the above nodesAnd what is the shared storage? For RAC, all shared storage devices for the cluster need to be available and usable by all ASM instances in that cluster.
Issue- we have RAC 11.2 clusterware listener using SCAN and listeners for all four clusterware nodes.
When we try to run the following RMAN command to migrate the single instance Oracle 11.2.0.1 datafiles it fails:The failure says: "+RMAN-10038: database session for channel ORA_DISK_1 terminated unexpectedly+". And this in itself does not tell you what the actual problem encountered is.
4- How to register the single instance with all four ASM instances and network services to resolve the above issue?Register what instance? ASM does not need databases or instances to be registered. It is a storage management layer. The cluster (grid infrastructure) layer is the one that deals with the registration (and management) of the various services and resources on that grid (e.g. ASM instances, database instances, SCAN and VIP, Listener services, etc).
5- Do we need to first run rconfig utility against single Oracle 11.2.0.1 instance to register with clusterware services BEFORE using RMAN to perform the datafile migration to ASM?Never used rconfig. See Support Note +RCONFIG : Frequently Asked Questions [ID 387046.1]+ for details.

Cluster with one 2 Node RAC and a Single Instance using ASM

Hi there,
i am not sure with one planned installation and want to ask, weather i am on the right track.
Some Facts:
Clusterware 11g
ASM 11g
Database 10gR2
AIX 5.3
3 Machines
2 Storages DS4700
My Plan
On Node 1 and Node 2 we install a RAC Database for an ERP Software
On Node 3 we install a single Instance Database for a Logistic Software
So i will install on all three Nodes Clusterware and an 3 Instances ASM - Cluster
I create 2 Diskgroups, one for the FRA and one for the Data, both on Luns on the DS4700
The RAC-Database and the Logistic-Database are using the same Diskgroups.
Is this the way to go for this circumstances?
The alternative is, as far as i see
Clusterware on an 3 Servers
One 2 Node ASM for the ERP Software
one Single Node ASM for the Logistcs
4 Diskgroups, because of the 2 ASM-Database 2 for the RAC and 2 for the Single Instance.
Please give me some hints, which way i should prefer.
My tendence is going to the first alternative. I like the idea to share the Diskgroups over more than on Database because of easy administration.
The load of the 2 Databases are completly different, the logistc software will nearly do nothing compared to the ERP Software, so this should'nt be a problem.
But maybe i oversee something, so please do not hesitate to tell me, i am completly wrong ;)
Thanks a lot
Jörg

Chris Slattery wrote:
why clusterware on 3rd machine ?
I'd have separate DGs but that's just me.If you wish to install ASM you need OCS installed on the machine, even if it is just one node at all.
It is a kind of a dependency, no OCS, no ASM

How to Create Manual Standby for a Oracle 11g RAC with ASM to Single Instan

Hi All,
I have a task to configure a Single Instance Standby Database with ASM for 2-node Primary RAC+ASM database.
Version using : 11.1.0.6 Oracle 11g --- *" STANDARD EDITION "* Please note datagaurd will not be supported in standard edition.
Primary database - 2 -Node RAC using ASM storage (All datafiles, redologs, controfile and archive logs)
Need to setup a single instance standby database manually and than using scripts to transfer the archive logs from primary server to standby server to do recovery time to time.
Please let me know if there are any configuration document(s) which can help me to set the manual standby? or need your kind help to give your valuable ideas how to go in above situation.
Thanks in advance

Well if the archive logs are stored in ASM on the primary nodes, you almost definitely want to be using RMAN to access them. Then to transfer between primary and standby there are many options, this is essentially the step that Data Guard takes care of - so if you (and I) are running Standard Edition, this is the part to "worry" about.
I'm not really sure what you mean by this:
As in standard edition the archive destination will be on ASMI don't think the Edition of Oracle (Standard or Enterprise) dictates where and how you store your archive logs, but it's possible I've misunderstood what you mean...SE dictates that database storage for RAC will be ASM, including archive log files. Anything else is not officially supported. I haven't tested but it may be that you can use LOG_ARCHIVE_DUPLEX_DEST to specify a local filesystem for archive log files as well.
If that doesn't work you'll have to script rman "backup as copy" jobs regularly and then transport the results of that.

By the way, it seems Robert has been pretty helpful, it's polite to give him some points dude. And since this is your thread, not mine, give him a "helpful" from me too :p
El DBA
Incidentally if you are forced down the RMAN backup as copy route then this will likely throw your current backup retention strategy somewhat, you'll need to think carefully about when an archivelog can be deleted following backup, how many times it might be backed up and so on. I do understand, and have argued for, the use of SE RAC. I also understand and have argued for and implemented manually managed standby a number of times. However by the time your primary database is a RAC instance and you need a standby for DR etc then you really have to look very seriously at whether Standard Edition is still the right investment or not. You will be spending a lot of DBA time managing and troubleshooting this, and you will find that it is less reliable than the off the shelf solution. I suspect that you are very close to the point where an EE installation becomes a worthwhile investment here.

How to change an ASM single-instance into a clustered ASM ?

Hi,
I have a node#1 with Oracle10gR2 installed (standard installation, not RAC).
Everything is in the ORACLE_HOME.
A unique single-instance database DB1 uses ASM#1 to access a diskgroup on a SAN.
I'd like to install Clusterware in a separate CRS_HOME (within the oracle account), and protect ASM#1 and the database DB1 using an application VIP.
The things is: I want to create another single-instance database DB2 on another node#2, with another ASM#2 instance.
I need a clustered ASM (with Clusterware) installation to do that because ASM#1 and ASM#2 need to access the same diskgroup.
I don't want to lose the existing data & configuration of the ASM#1 instance.
What modifications I need to do in the current ASM#1 instance on node#1 to make it Clusterware-aware ?
(Again, it's not a RAC installation...)
Thanks

Hi,
I finally found this Metalink Note 452758.1, which describe the procedure....
Any feedback about this ?

How to convert single instance10g db to 11gR2 RAC with ASM

Hi,
I need your help to decide the plan about how to convert single instance 10g database to 11gr2 rac with asm.
I can have about 6 to 8 hours of downtime to upgrade and move to rac with asm.
db size is about 1.5tb and on AIX.
here is my plan....
1) install 11gr2 rac with asm on two nodes
2) verify rac installation and clustered asm
3)install 10g oracle binaries( yes 10g )
4) shutdown production db ( machine prod )
5) make copy of production and restore on 1st node ( using shadow image , so it's quick and its file system )
6) upgrade db to 11g ( still of file system )
7) after successful upgrade, move to asm ( rman backup )
8) add another node
does it look okay ? OR is there a better approach to save time?
can someone help me ?
Thanks...

Thanks ...
So here is what I thought... suggest if something is not right...
1) install 11gr2 grid infra on node A and B with ASM
2) stop CLUSTER ON BOTH NODES.
3) shutdown prod db on 10g ( downtime starts )
4) take rman cold backup
5) restore rman backup on node A on ASM ( as if single instance 11g , no rac parameters )
6) mount and run upgrade script for 11g, then open db with 11
7) after successful upgrade, shutdown db node A
8) change all rac related parameters, spfile,undo,redo for rac environment on both nodes
9) open db in rac environment
can I do this way ?
My only question is, even though I installed rac on node A and B, in step 5 and 6 I'm using only node A as if it is single instance. Is it possible ?
if it is then I'm good to go...
Thanks for all suggestions.

Cloning DB to single instance ASM issue 11.2.0.3

Hi All,
Having trouble cloning a DB via OEM to a new server I just built up which utilizes a single instance ASM.
Creating a new DB via dbca onto ASM works no problems.
When doing the clone it fails on the source server during the duplicate database step with the following output:
RMAN>
echo set off
RMAN>
connected to target database: SOURCEDB (DBID=3592949595)
RMAN>
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-04006: error from auxiliary database: ORA-12543: TNS:destination host unreachable
It appears as though the target server doesn't start the new DB up in nomount because control files don't exist yet.
The init ora file exists on the target server and when trying to run "startup nomount" manually it fails with:
SQL> startup nomount
ORA-01078: failure in processing system parameters
LRM-00117: syntax error at ',' at the start of input
The init ora file looks all correct except for the last line:
control_files='',''
Any ideas on what else to check?
No firewall issues, both source and target servers can ping one another and port 1521 is open on both.
Both source and target servers are running 11.2.0.3.
Looking forward to some much needed help as this has me stumped.

If I were you, I would open in nomount the Instance were its going to be duplicated to verify all the parameters are correct even before starting the duplicate, also you can change several parameters in the duplicate command
run {
allocate channel prmy1 type disk;
allocate channel prmy2 type disk;
allocate channel prmy3 type disk;
allocate channel prmy4 type disk;
allocate auxiliary channel stby type disk;
duplicate target database to test_db from active database
spfile
parameter_value_convert 'testgg1','testgg2'
set db_unique_name='testgg2'
set db_file_name_convert='/u01/app/oracle/oradata/testgg1/TESTGG1/datafile/','/u01/app/oracle/oradata/testgg2/TESTGG2/datafile/'
set log_file_name_convert='/u01/app/oracle/oradata/testgg1/TESTGG1/onlinelog/','/u01/app/oracle/oradata/testgg2/TESTGG2/onlinelog/'
set control_files='/u01/app/oracle/oradata/testgg2/control/control01.ctl','/u01/app/oracle/oradata/testgg2/control/control02.ctl'
