Dbca on single instance and crs problem

Hi,
in a machine was removed the crs software.
I want to creata a single database instance on a single machine.
The SO is RH 5.5 and the db is 11.2.0.2.
I don't know what was done, but now, if i try to create a database with dbca, i get the following error:
oracle.ops.mgmt.has.ClusterUtilException: PRKH-1010 : Unable to communicate with CRS services.

In 11gR2, you installed the grid infrastructure when you did your cluster install. This took care of CRS and ASM. Now you've removed CRS. If you're still using ASM, this would cause a problem because that still relies on the grid infrastructure.
is there more info you can provide on the steps you took to get where you are? It may be good to just reinstall the grid infrastructure before proceeding.

Restore single instance rman backup to rac database

Hello all. I have a 10gR2 single instance database that I have been taking backups using the oracle's suggested backup strategy, that is, once full database backup and incremental backups here and there. That's is all fine as I have (many times) being requested to rollback the database resulting in all operations being sucessfull.
However, since this is somehow a pre-certification database, I am now being tasked to restore this database to what is going to be our production database, which is a 10gR2 rac database. I have already set up the RAC database sucessfull.
Now, my question is: How can I take one of the backups that I have on the single-instance database and restore onto my RAC database ?
Some information about the infraestructure:
Both operating systems are HP-UX. Single instance is 11.23, RAC database is 11.31.
Both database are using ASM as datafiles storage and flash recovery area storage.
Any help will be appreciated!
Thanks!

In general terms, there are several ways you can convert a single instance into a rac intance, and it involves much more activities than just adding redo threads.
Use of DBCA
Enterprise Manager Grid Control
rconfig utility
Considering your case, if you don't currently have Grid Control, the first option is rconfig.
1. Migrate your database from the current environment to the target environment by a regular cloning procedure, this will create a single instance into your rac environment. Your regular rdbms rac installation allows you to manage both, single instance and rac instances. Use this procedure to clone your database to the target RAC environment using recovery manager --> http://madrid9999.googlepages.com/rmancloneadatabase
2. Once you have started your database in the RAC environment proceed with the rconfig tool, this requires some files to perform the conversion, the ConvertToRAC.xml file which is located at $ORACLE_HOME/assistants/rconfig/sampleXMLs
3. Once you copied/edited the ConvertToRAC.xml file, you have to run the rconfig. Save the ConvertToRAC.xml under a different file name.
rconfig editedConvertToRAC.xml
4. For further reference on the rconfig command, you may refer to this page Oracle® Real Application Clusters Installation Guide

Multiple Single Instance DB Conversion to Cluster Database RAC

Hi,
Good Day.
we are in planning phase to perform an activity, in which 8 existing (Single Instance) and 1 new database will be consolidated in ONE Oracle RAC Cluster database.
Kindly share your ideas, to perform the consolidation smoothly with minimal downtime.
can any one share the cons/pros, what if we create MULTIPLE RAC cluster databases instead of one cluster database?
Thank You.
Regards,

The cons are pretty much the same as running multiple instances on a single server: Tuning will be much harder because you will have to look for bottleneck and depletion of common resources (CPU, RAM, IO) across all your instances instead of one (where you have lots of nice and integrated features). There is the potential for contention between resources and since each instance/database has its own SGA (and they are not shared) you will potentially waste a lot of ram for stuff that is redundant between the instances.
But if you still think this is something you want to do, you should take a look at the 'server pool' feature. It will give you some more control over how your databases/instances should be ditributed across your rac (there is propably no need for all databases to be running on all servers at the same time)

Multiple Instances and schemas to One

Hi,
Good Morning to all gurus.
Using Oracle Version 11.2.0.2
We have a database With 4 instances and Each Instance will be having 10 to 15 schemas Based on Countries. Here in all schemas we will be having Huge data's (count may be 3 to 5 crores for some 10 tables)
Now am keen to Know If i change the above to a single instance and Single Schema(Common for all countries) What Pros and cons Will be there (Technical).
Any Links or Answers are highly appreciated.
HOPE GURUS Here can help me study and understand the above scenarios.

Seperate schemas have advantages with security, privacy, seperation of duties, and change control. Seperate schemas also have the advantage of logical granularity / grouping for easier management, upgrade, decommission, scalability, hardware or software migration.
Yes, you can develop applications faster if you don't have to think about security, scalability etc, but it will come back to haunt you later.
RobertGeier
AND
Separate schemas have the disadvantage of requiring additonal grants and privileges to support the reference of non-owned objects used in stored code and to support FK definitions across tables owned by different users.
Naming standards and system codes can be used to identify and segregate objects defined under one schema.
The use of solid naming standards with a well chosen group of owners (schemas) would likely be a good compromise. The choice really depends on how large the applicaiton is going to be object wise and how integrated the objects are going to be. The more integration the less separate owners is beneficial.

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

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

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

BW and R/3 in the same box with a single instance ECC 5.0

Hi anybody using this scenario of having bw and r/3 in the same box....we are planing to consider in our project.
will be happy if anybody can provide me some help on this.
thanks and regards

HI Neel Kamal,
I think its a better option to distinguish OLTP like R/3 or ECC and OLAP like BW rather on a single instance
from the above posts
Let us know if this holds good

High number of threads and high CPU usage on a single instance

Without any apparent reason, in some moments of day the website reports an increment of the HTTP Queue Length from an average of 10/20 queued requests to 100/200 and more.
In that period of time the Average Response Time increases but the number of the requests on the website don't. Even increasing the instances it doesn't help to resolve the problem (maybe it just reduced it).
It seems that the problem is not related to the traffic on the site. This issue happens either when the traffic is high or low.
The autoscaling works well, we don't have peak of traffic but always a slow increasing of requests and the CPU is always below the 50% (memory too). The issue is resolved by the swap of the site and sometimes it's resolve by itself after a while.
What I discovered when the issue happens, is that there's an instance (just an instance only), that has an high number of threads and CPU usage on the W3WP.exe process and these values are above the mean than the other instances. Eg, instances are around
50/60 threads and 10/20% of CPU, the instance with the problem has 200 threads and 50/60% of CPU. If I kill the W3WP process on that instance the issue is resolved.
I monitored the HTTP requests, I tried the website extension "Diagnostics as service" but I can't discover anything that can help me to understand the problem. Of course, there are many requests that go in timeout but it is a consequences of a
unresponsive instance.
On the web hosting plan there are only two sites: the production site and its staging which is used for update of the production only and it's always sleeping. Plus, no webjobs are running on this site.
What can I do to gather useful information that can help me to understand the reason of this problem?
Thank you!

"Does the instance with the high counts receive more traffic than the other instances? Is it possible that the load balancer not
working the way it should be?"
How can I get that information? I can't see metrics for a specific instance
"Does it always happen to the first instance?"
I will check it better, but in the order given by the Processes panel it's the second instance which has the issue. The scaling is at 2 instances for the most part of the time (it's the minimum).
Maybe one time it was the 3th instance but I'm not sure, I'll give it more attention.
" How long do these moment last?"
The time can be 10 to 30 minutes, but I fix it as soon as I see the problem. It's not the down-scaling to resolve it because in these situations the CPU as well is high so the scaling holds or increases the number of instances.
"- How often do these moments occurs?"
It occurs quite often, 2/4 times a week.

Data guard performance problem (rac to single instance)

i have a table it has GPS data, and gps table has too many data, 5 millions,
iam using RAC (2 nodes 11gr2). standby database is single instance data guard,
single instance database (standby)'s hardware cpu is lower than RAC machines. rac nodes have (15k) disks, standby has (7200rpm),
so i dont want to use GPS tables on data guard system, i dont want to run GPS table's DML commands (delete, insert), i think it may increase performance,
is it posible? what is your advise?
any feedback makes me happy,
best regards

it's not possible with data guard, but you can use streams or golgengate for this purpose. Have a look at dataguard performance tuning guide. Maybe there is something you can fix on the configuration to be faster.

Services are up and running - problem with browser access to Apps instance

We are using 11.5.10 and I have just finished a clone from our TEST environment.
We cannot connect to the login screen however.
I suspect there is a problem with the address we are using
http://*****.********l.com:8002/OA_HTML/AppsLocalLogin.jsp is the address for our TEST instance. and 8003 was for the previous encarnation of our newly cloned system.
Which configuration file can I check to see how this instance was configured?
I am looking at the adcfgclone returns and see nothing much except
Target system proxy hostname (used default)
Target system proxy port [80]: (left as this)
Should I check the context file for the new instance?
I am checking the webport , but no luck.
Again, in the context file, I see
<oa_web_server>

<hostname oa_var="s_webhost">****cl</hostname>
<externURL oa_var="s_external_url">http://****cl.****.com:8004</externURL>
(8004 was the last port used for this instance before cloning)
Should I check any specific table in the new instance??

Switchover between primary RAC and standby single instance

Hello All,
I am using Oracle 11gR2.
I am trying to do a switch over between primary database (RAC 2 nodes) and physical standby (single instance)
If my Primary is single instance i was following the below steps:
On the standby
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
On the primary database:
alter database commit to switchover to standby with session shutdown;
shutdown immediate;
startup nomount;
alter database mount standby database;
On the standby again:
alter database commit to switchover to primary WITH SESSION SHUTDOWN;
On the new standby:
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;now, and since my primary is RAC when i am trying switch over I am getting the below error:
SQL> alter database commit to switchover to standby with session shutdown;
alter database commit to switchover to standby with session shutdown
ERROR at line 1:
ORA-01105: mount is incompatible with mounts by other instancesPlus that when I want to apply the remaining steps (below step), should I do it on each instance alone? or is there anyway to do it using the srvctl command:
alter database mount standby database;Regards,

Hi,
Since You are using 2 node RAc as primary, so for switchover operation you need to shutdown
one database instance( Suppose instance 2).
Suppose your node1:
hostname is dcpdb1
and node 2:
hostname is dcpdb2
and standby hostname is drpdb1
So follow this steps for switchover .

Single orchestration instance and Sequential convoy

Hi
I had read some Biztalk documents, I saw that talk about single orchestration instance and sequential convoy. But
I'm not sure with what situation use them?
1. What are scenarios use single orchestration?
2. What are scenarios use a sequential convoy?
Thanks in advance!

A single orchestration or a singleton provides you with a mechanism to control the throughput of message through the system. The behaviour of BizTalk is to trigger a thread for every message instance and when handling Message Batches, this is often not a
good thing as after debatching you land up with lots of messages, each of which trigger off an instance of the subscription.
A convoy is a more generalized pattern. If a convoy is deployed for the same message, it becomes a singleton. A convoy can be used to sequentially process different (but interlinked) messages. To take a very loose example, the entire process from order placement
to goods shipment to invoicing to payment can be implemented as a convoy with each different type of message being handled by one instance and being received from a single port. A convoy can also be used to implement the gather portion of the scatter-gather
pattern which is usefull when you want to aggregate the results of a batched processing, etc.
Regards.

%ORACLE_HOME% instances of SOA Suite. I can create an oc4j instance but of
course it doesn't have any SOA Suite stuff deployed to it. I tried to see what
the install would do with this new oc4j instance but it wants to create a new
%ORACLE_HOME% with an entire installation of SOA Suite.
Is there some sort of way to clone oc4j instances that have SOA Suite deployed to them so that you
don't need multiple %ORACLE_HOME% instances?
### How is this Issue Impacting Your Business ###
We really don't want to have a lot of %ORACLE_HOME% instances to have to maintain. We are
migrating projects over from our current integration server product and we'll
have potentially dozens more BPEL and ESB projects. We definitely want to
group and isolate projects so that outages of one project do not bring down
others that are unrelated.
We are currently experiencing periodic problems with one BPEL project that requires recycling but all the other BPEL and ESB
projects get recycled also. If we could put this project into it's own java
process without creating another SOA SUITE instance, it would be a big
help.

=======
You can create multiple domains in BPEL or create multiple systems/groups in ESB to group different projects.

We have been using systems/groups in ESB but they all run under the save java.exe process. I would assume that having a seperate domain in BPEL would also run in that same java.exe process.
Right now, the one BPEL project we have a problem with will gobble up all the JDBC connections from time to time and that requires a recycle of SOA Suite, which means all BPEL and ESB projects that run in that java.exe process get recycled also. We're working that issue in a different ticket.
It would be nice if the SOA Suite installation would install against a new oc4j instance and not assume it has to create a complete %ORACLE_HOME% instance. The components of SOA Suite seem to be J2EE based components.
Scenario: I already have an oc4j instance called oc4j_soa and a complete %ORACLE_HOME% installation of soa suite. I then create a new oc4j instance from Enterprise Manager. Then I would deploy the esb-dt, esb-rt, orabpel, etc. components of SOA Suite to that new oc4j instance and modify the necessary config file so that it can work with OHS and the SOA Suite Databases. Is this possible?
Does anyone have any experience with this or do people typically install multiple complete installation of SOA Suite with mulitple Oracle Homes?

Hi,
yes, on metalink you get in touch with real experts....
You have to install serveral application servers to get different ORACLE_HOMEs.
For each one, you can install a BPEL PM.
But: For each BPEL PM you need your own database instance, or you have to configure them as a clustered BPEL installation.... (but i do not know if this work with non RAC DBs)
