Grid Control 12c and high availability databases
Hello,
In the context of high availability databses, my configuration is as follow:
2 AIX servers on 2 sites with shared storage -> Site1 and site2.
During normal operations databases are on site1. In case of disaster, databases can fallover on site2.
On my Grid Control, 2 agents are installed: One for AIX on site1 and one for AIX on site2.
Databases have been discovered on AIX:site1
Listener is a virtual address and can also fallover.
What are the possibility on the grid side ?
Do I have to discover also the databases on site2 ?
Actually, Listener is seen down on the site who has not the databases.
Is there a way to only configure the Listener virtual address on the Grid ?
Regards
Hi,
Basically you have to relocate the targets to the new agent (the one installed on site2). I haven't done that, but I expect to work fairly easy and smooth. Refer to the following section of Cloud Control 12c manual:
Configuring Targets for Failover in Active/Passive Environments
Regards,
Sve

GCS on grid control graph is high and write data slowly
We writed more data to Oracle RAC 10.2 + ASM on Redhat.
It's slowly. When we check grap on Grid Control, we found high stat on "Global Cache Block Access Latency".
How can I tune or investigate?
###remark
Oracle Cluster 4 nodes (10.2 + ASM on redhat 4)
interconnect CAT 6 (1G) and use bondingJust to be certain, how slow and which part of the Global Cache component:
AWR Report threshholds are (lower boundary - typical - upper boundary)
Avg time to process cr block request 0.1 - 1 - 10
Avg Global Cache cr block receive times 0.3 - 4 - 12
Avg time to process current block request 0.1 - 3 - 23
Avg Global cache current block receive time 0.3 - 8 - 30
You might be losing blocks? I have a link to this article...
http://www.dba-oracle.com/real_application_clusters_rac_grid/cache_stats.htm
I modified the query found at the link above for more nodes:
SELECT A.INST_ID "Node ID",
(select B.VALUE from GV$SYSSTAT B where B.inst_ID=A.INST_ID and B.NAME='gc blocks lost') "GC BLOCKS LOST",
(select C.VALUE from GV$SYSSTAT C where C.inst_ID=A.INST_ID and C.NAME='gc blocks corrupt') "GC BLOCKS CORRUPT"
FROM GV$SYSSTAT A
group by A.INST_ID
order by 1;
Each should come back zero or close to zero. If it doesn't then check with your Linux admins to tune to the interface settings. A tuning link is also in the above URL. -

The line "skipping bad jar, '/u01/binaries/wls/wls1035_generic.jar'" is the one that's worring me. Can it be corrupt? Or it is something else?
Thanks in advance.Its too early to conclude the issue is a bug with out looking into the logs. For the same reason i requested you to open an SR so that we can have a look at the logs and identify the cause. If you are Oracle employee then you can share the VM details else we need logs to debug this further. If any one from your company can open an sr and share logs then that will be helpful. Can you also check if the shiphome that you downloaded is all correct and checksum/byte matches to what is mentioned on OTN.

Can Grid Control 10gR2 create a standby database when primary db uses ASM?
Does anyone know if Grid Control 10gR2 will be able to create a standby database when the primary database uses ASM for data files, redo log files, and archive log files but the standby database will use mounted disks? If it can, would it matter that the primary db will be a RAC cluster and the standby will be a single instance db?
I appreciate your reply and hope you are correct. Have you had a look at the 10gR2 Grid Control to confirm this or are you only going on published statements? The reason I ask is because previous versions of Grid Control claimed to support ASM but they would only allow you to work with them AFTER you had created a standby database manually but you couldn't actually use Grid Control to create a standby database from a primary database that had its log files on ASM disks.

Grid control agent and data guard in mount mode
Hello,
I would like to know how you manage your data guards when you do not have the license for active data guard with the grid control agents. The standby database is in mount mode, so the agents cannot query the database.
What do you guys do in such cases? Remove the agent? Or wait till a switchover?Check this out with a mounted database

Can Grid control 11g monitor Oracle 9i database
Can Grid control 11g monitor Oracle 9i database? This is on Linux5.7
Thanks for the help
s.Yes but Enterprise Manager 11.1 Grid Control requires the 11.1 Agent.
Then go to the Targets tab, then Databases. It should self-discover the 9i database.

For a true load balancing and high-availability OHS, OPMN, and mod_oc4j
i have read this link of Enabling Clustering on oc4j9.0.4 standalone app server
http://www.oracle.com/technology/docs/tech/java/oc4j/htdocs/getstart.htm#1015479
To test the clustering, start up the load balancer by executing "java -jar loadbalancer.jar".
C:\OC4J_EXTENDED\j2ee\home>java -jar loadbalancer.jar
In a future release of Oracle Application Server, loadbalancer.jar will be
desupported. Because of this, we strongly suggest that you discontinue your use
of loadbalancer.jar in this release. Under high loads, loadbalancer.jar may not
function properly. For a true load balancing and high-availability solution,
please move to use OHS, OPMN, and mod_OC4J. For more information, please see

what load balancer should i use for web clustering
<frontend host="balancer-host" port="balancer-port" />
balancer-host=localhost
balancer-port=80
for all nodes i mentioned same host and port in http-web-site.xml.Is it correct?
i completed all the steps and run http://localhost:6666/session/SessionServlet
i hit 3 times
in the different browser http://localhost:7777/session/SessionServlet
instead of coming 4 it starting from 1 only.can i use this loadbalancer.jar or not?

Load balancing and High Availability topology
Our Forms 6i client-server application currently runs on Citrix farm of 20 Windows 2000 boxes (IBM Blade Servers 2 CPU and 2 Gig Memory).
Application supports 2000 users.
We are moving to AS 10g r2, forms 10g and the goal is to use same hardware, 20 Windows boxes (or less), for intranet web deployment.
What will be our best choices for application Load balancing and High Availability?
Hardware load balancer, Web Cache, mod-oc4j? Combinations?
Any suggestions, best practices, your experience?Gerd, I understand, that you are running 10g web forms through the browser, but using Citrix for deployment. This means that in addition to Application Server and Forms runtime sessions, it will be separate browser session opened for each user. What the advantage of this configuration?
Michael, we are aware, that Citrix is not supported by Oracle as a deployment platform. That only means that prior contacting Oracle Support we have to reproduce the problem in standard environment. It was never been a problem to reproduce problem :) We were using Citrix as a deployment platform for Forms 6i client/server for 4 years, but now we are forced to upgrade to 10g.
We are familiar with various Load balancing options available. The question is which option is the most "workable" in our case. -
Can you provide some information on how Tuxedo can be configured in a high availability
environment. Specifically running Tux 7.1 on AIX 4.3 with HACMP/ES. I am planning
on running with a 'cascading N+1' configuration and have concerns over the ability
of the standby node to take over a failed node succesfully due to config dependancies
on the machine name. Is there a white paper detailing use of Tux in a high availability
environment ?Found the answers and thought would share it.
1. Can load balancing be achieved in MP setup or is this a high availability configuration?
Both - MP supports load balancing and high availability 2. In an MP setup, can a workstation client continue to work even after the master node gets migrated? If so, can we have both (or all nodes and their WSL) listed in WSNADDR for this to happen
Correct. -
Hi All...
Question about OIM and High Availability and licensing:
If I license OIM for production Server and OIM connectors and I want two have a 2nd machine that serves as stand-by machine, do I have to licence OIM and connectors for the stand-by machine?
Thanks.Scheduled tasks tuns on a specific server so running in a cluster won't really help you with having redundancy for scheduled tasks.
If you have very big scheduled task you have a few options:
1. Introduce milestones
Change the code so that the process does the work in batches. If something happens you can return to the last milestone instead of having to go back to scratch.
2. Multiple communicating threads
Implement batching and also run multiple threads that coordinate the effort and makes sure that there always are instances running on all nodes. If not spawn more instances until you get threads on all nodes. If a node dies the work is journaled back and is divided between the other threads. Would work but would probably get very complex.
Oracle recently ran training courses in OIM HA. I attended the course but I can't really distribute the material so please contact your Oracle account manager and ask them about the training.
Hope this helps

Database Grid Control 10g and Oracle 8i v.3....
Hi ,
Is it possible for Database Grid Control 10g to administer and monitor the Oracle 8i v.3, namely Oracle 8.1.7. database ...?????
Many thanks ,
SimonYes, that is possible. We are using OMS 10.2.0.2, Agents 10.2.0.2 to monitor 8.1.7.4 Databases.

Oracle Cloud Control 12c and licensing
Hey Guys, Can someone please elucidate on the Cloud Control 12c licensing requirements?
Following are all the licenses we currently hold:
1. Oracle Enterprise Edition DB
2. Oracle RAC
3. Oracle Active Data Guard
4. Diagnostic and Tuning Pack
5. Partitioning Option
6. Advanced Security Option
7. GoldenGate
My understanding is that I could install and access Grid/Cloud control as long as I have the Diagnostic and Tuning Pack - and of course to all products we are licensed for.
Questions:
1. Do I need any license for Weblogic server?
2. Can I setup OMS in a clustered architecture?
3. Can I have the RAC database for the repository?
4. Can I access the High Availability options - DG etc?
5. Can I administer RAC and GI services from Cloud Control?
I would've thought that as long as I have access to the underlying DB options, Grid/Cloud control can be used to administer over them.
Could someone please help in clearing this up?
Regards
SridharI highly recommend you to read the Enterprise Manager Licensing Information:
http://docs.oracle.com/cd/E24628_01/doc.121/e24474/toc.htm
Quick answers for your questions:
1) No, as long as you use it only for EM
2) Yes you can.
3) You need to buy licenses for RAC option (for both nodes) and DB licenses for second node.
4) You mean accessing DG pages on EM pages right? Yes you can. They do not need any license pack. Btw you can check if a page requires additional licensing using "setup > management packs > packs for the page" menu.
5) Yes you can.
But as I said, it's better to read the licencing document by yourself, and contact Oracle sales for more information. -
Grid Control performance tab not available when on the target home of ASM
I noticed recently that the "Performance" tab/link is not available when you are using 10g Grid Control and you are on the home page of an ASM instance. Can this be explained?
Hi MarGur
I try to help you. The OEM Grid Control in some times not discover the Oracle 9i databases and you must to add manually.
First, check in your target machine that the user owner of agent software have rights of read and write in the ORACLE_HOME directories of Oracle 9i databases.
Go to Grid Control Console
Select Targets ---> Databases
Press Add --> Select the host ebisdb2.oneshield.com and press continue
The automatic discover process begin. When finished is very normal that nor discover the Oracle 9i databases. You press the Add manually button
in the page that appear you must entry all the configuration information of database:
ORACLE_HOME directory
DBSNMP USER
DBSNMP PASSWORD
HOSTNAME
PORT
SID
Check that the dbsnmp user in your database is unlock and press the TEST button to verify the connection work fine.
After this many windows appear of configuration process, and you will put the sys password and host credentials.
If you have problems, tell me
