Quick question:  redundant OMS databases for Grid Control

Dear Friends,
I am wondering if it is possible to configure redundant OEM Management Server databases on separate servers and how would that be done?
I don't think it is possible to have an agent write to more than one OMS database, so how is it possible to have our OEM management server redundant?
Is running DG the only option?
Thanks.
Ji Li

Damorgan:
I thought I remembered doing this at a previous site that I worked a few years ago, but I don't remember how I did it.
Will I need to configure dual listeners, or use separate ports for the dual agents?
Do you know where there might be instructions for how to set up and run dual agents on the same server?
Thanks again.
Ji Li

  • Database limits for Grid control repository?

    Document "Oracle® Database Licensing Information / 10g Release 2 (10.2)" [Part Number B14199-10] discusses the restricted use license of database for grid control repository and rman repository use.
    nfrastructure Repository Databases A separate Oracle Database can be installed and used as a Recovery Manager (RMAN) repository without additional license requirements, provided that all the Oracle databases managed in this repository are correctly licensed. This repository database may also be used for the Oracle Enterprise Grid Control repository. It may not be used or deployed for other uses.
    A separate Oracle Database can be installed and used as a Oracle Enterprise Manager Grid Control (OEM Grid Control) repository without additional license requirements, provided that all the targets (databases, applications, and so forth) managed in this repository are correctly licensed. This database may also be used for the RMAN repository. It may not be used or deployed for other uses.
    There is no discussion of licensing requirements for options of the database (RAC, partitioning, etc) when the database stays within these repository use restrictions. Therefore it is unclear whether the Grid Control can be configured to provide appropriate monitoring without additional licenses.

    This is the reply I received from release
    management:
    If they have deployed an EE edition of the database
    as an OEM repository, and then want to protect that
    with RAC or Data Guard, or make more Secure with ASO
    or Database Vault, or indeed get any of the
    additional benefits any of the options provide, then
    they will need to license the option.
    Let me know if that is still not clear, and I'll go
    back again.Thanks.
    There is a minor inconsistency in their response ... they say "if deployed on EE". However, as far as I know OEM repository required VPD, which is available only on Enterprise Edition (see http://download-east.oracle.com/docs/cd/B16240_01/doc/em.102/e10953/pre-installation_req.htm#CHDGIEAD)
    However, it is quite clear that 'they' are telling us that the RAC option is not inherent in the "Special Use Licensing" as described http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#CJAHFHBJ .
    The implication (not necessarily a topic for this forum) is that the OEM is not guaranteed to be able to provide basic monitoring and reporting functionality without additional license fees to make OEM more highly available than the targets being monitored.
    It would be nice to have the information about which Oracle products (database and app server) have included licenses with a basic Grid Control install and which require additional licenses as part of Chapter 1 of http://download.oracle.com/docs/cd/B19306_01/license.102/b40010/toc.htm (That document goes into excruciating detail about the extra packs, but ignores the basics.)
    For that matter, since OEM Grid Control can not be purchased, it would be nice to have a list of products that provide license to install Grid Control, again in Chapter 1 of the Grid Control Licensing document listed above.
    I appreciate your time in having dug into this.

  • A possible bug for Grid control?

    Hi, Dear all,
    We installed Grid control 10.2.0.1 on Redhat Linux R3 with existing database(10.2.0.4).
    During the installation, we succeeded for repository creating but failed at OMS Configuration.
    When I start oms in cmd line, I got the following error: the repository database can not be connected.
    The description for the environment:
    1. OMS server and repository database are installed on the same server, on which HA is used.
    2. There are two floating IP on this machine,
    IP | server name | used for |
    xx.xx.xx.124 | cnsz030318 | oms server |
    xx.xx.xx.80 | oem.db.paci.com.cn | repository database |
    3.When we installed the oms with OUI, the repository server we input is oem.db.paci.com.cn
    The problem we found:
    During the installation, the repository was created successfully. But it failed at OMS configuration.
    The error we got: the repository database can not be connected.
    there are two lines in emoms.properities which seems strange:
    oracle.sysman.eml.mntr.emdRepServer=oem.db.paic.com.cn
    oracle.sysman.eml.mntr.emdRepConnectDescriptor=(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=cnsz030318.db.paic.com.cn)(PORT\=1535)))(CONNECT_DATA\=(SID\=oem10g)))
    The emdRepServer is what we have input on OUI:oem.db.paic.com.cn. But for the connectDescriptor, it is changed to "cnsz030318.db.paic.com.cn", which does not exist at all!.
    Now, we have worked around this problem by adding "cnsz030318.db.paic.com.cn" in the /etc/hosts.
    But my question is, why the connectDescriptor set the HOST\ as cnsz030318.db.paic.com.cn? Why does it not use the name we input in OUI (oem.db.paic.com.cn)?
    Maybe it is a bug for Grid control?

    Did you install with "Use existing database" or "Use new database"?
    I recommend that you use fully qualified domain names only!

  • Unable to connect to Database using Grid Control

    Hi,
    I am attempting to connect to my Oracle Linux Machine which has 2 databases FROM my 10g Grid control which is on a Windows XP 32 bit.
    Although I can login to the actual linux box with the host and database credentials ; I cant use the same to login to the database using Grid control.
    I have tried testing the connection using Grid Control >> Preferences >> Preferred Credentials >> Host ; but its just not recognizing the credentials as correct.
    When I attempt to startup the database using the host and DB credentials : ERROR MESSAGE : <servername> : <servername> comes up.
    My agent on linux box is up. My Listener is running fine.
    On my Grid control .. i have the DB, OMS, and Agent running as well.
    Any inputs on this issue, I'd appreciate very much.

    Thanks for your reply.
    Under Hosts on the Main Grid Console Home Page >> "server3.sam" Status shows UP. This server houses my 2 databases. But when I click on Databases >> it shows Instance DOWN.
    Status          
    Failed
    Details          Failed to connect to database instance: ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach).
    I have verified that my lsnrctl status is good on the linux box. My target agent is up and running on it as well.
    So I try to start the STARTUP button >> I enter the HOST Credentials of the Linux box and the Database credentials which I use "SYS" (in upper case - just in case that mattered) and choose SYSDBA ;
    Error Message
    server3.sam: server3.sam
    I created a new dba account and try to login ... dont seem to work ; I tried using SYSTEM account and even altering my sys and system passwords .. all turn out negative.
    And the ANSWER to your question ---> Grid Control >> Preferences >> Preferred Credentials >> Database Instance >> corresponding to my database name ; I enter my sysdba username / password AND the host username / password of my Linux box >> TEST >> which also turns out negative.
    This entry is auto filled in since I "checked" the box "Save as Preferred Credential"; initially when I tried to start the DB using the STARTUP button.
    By the way, my Win XP doesnt really have a password set under User accounts.
    Any suggestions please ?

  • Problem Load Balancing connections for Grid Control Console on port 80!

    I have two OMS and I'm balancing connections for Grid Control Console using a Software Load Balancer according with "Oracle Enterprise Manager Advanced Configuration". I have success where the load balancer is listening on port different to 80. When I configure Load Balancer to listen on port 80(architecture requirement) and distribute load between the two OMS(Port 7779), when login to Enterprise Manager Console the URL on the web browser changes to the port configured for HTTP server (port 7780) wich produces an "unable to connect" error message; and this behaviour also happends in some of the internal links of Grid Control Console too. Any ideas?
    Thanks in advance!

  • What is Hardware/O.S. Recommendations for Grid Control server

    I understand both Linux and Window servers are supported for Grid Control Installation.
    However, since we are running Exadata database and cells, what would be your recommendation when we choose which O.S. we should run G.C. on?
    Since the entire Exadata environment is running Linux, so, personally I'd prefer to use Linux server. But, what is your preference, and please detail your reasons.
    Thank you!

    Grid Control (OEMGC 11g) for Windows is only available (certified) for 32 bit Windows. So you can run into memory limitations, dependeing on the number of agents/targets you will be monitoring. Second you have to install Cygwin on your Windows server if you want (or need) to be able to SSH to a Linux/Unix server. Installing Cygwin is very problematic to say the least.
    If you would use OEMCC (12c), and I don't know why you wouldn't, you can install the 64 bit version for Windows however you still have to install Cygwin.
    So in your case I would go for the Linux version.

  • Naming database inside Grid Control

    Hi,
    I have one question about database names in Database tab of Grid Control.
    What is happening:
    I have static definition of my services in the listener.ora file, and when I have installed Grid Control Agent on this node
    Oracle registers name like this in my databases tab of Grid Control:
    DBNAME_HOSTNAME.DBDOMAIN
    I want to register my database like dbname.dbdomain. Is it possible? Can I have any control of naming of databases in Grid Control?
    When I haven’t static definition of services in my listener.ora file, database is good registrated (*dbname.dbdomain*).
    Thanks,
    Best regards
    Dragan

    Yes you have control of naming databases in Grid Control.
    When you add a database target to grid control, after chosing the host you'll see the databases on that host. Under the databases there is an option: "Manually add" If you chose this option you can name the database target however you want. so you can delete the database target from grid, and add again with manual option...

  • Standby Database for GRID instance

    Hi All,
    I have a requirement from a client to provide a Standby database (Physical or Logical) for the GRID control instance. Baffled by this, I tried to explain that the GRID instance is very small and may not require a standby. The client is adamant.
    So, has anyone had any experience (experimental or otherwise) of configuration of a standby for GRID?. If so, how? and which would be a feasible option, Physical or Logical?
    Any feedback is appreciated.
    Regards,
    Timothy.

    Connection to the repository failed. Verify that the repository connection information provided is correct.Tried to google and search the forum, the message is not very selective and got few relevant resut.
    Hope your exterts can point me to the configure file where I can verify the connetion to repository. Alos some one would share with me the knowledge on the following topics
    1) What are the processes/components of Grid Control ? I am aware of oms, opmn, and a process run as /u01/app/midware/oms11g/ccr/bin/nmz -cron –silent. ANy others? What are their functions?
    2) Location of configure files, log files and binary executables of this processes/components.
    Many thnaks.

    Hi,
    to check if the OMS is running properly execute the command "emctl status oms" ($OMS_HOME/bin).
    The result should be "Oracle Management Server is up".
    To check which components are currently running execute the command "opmnctl status" ($OMS_HOME/opmn/bin).
    The result should be something like:
    Processes in Instance: EnterpriseManager0.<host
    -----------------------------------------------------------+---------
    ias-component | process-type | pid | status
    -----------------------------------------------------------+---------

    WebCache | WebCache | 27085 | Alive
    WebCache | WebCacheAdmin | 27086 | Alive
    Executing this command will answer your question whioch components need/should be up when using OEM/GC.
    You will find some logfiles of the OMS under $OMS_HOME/sysman/log (e.g. emoms.trc, emoms.log). Please check logfile OC4J~OC4J_EM~default_island~1 under $OMS_HOME/opmn/logs as well...
    To start the OMS you might try the command "opmnctl startall"...
