OEM 12 c Cloud Control: two agents on the same host.

Hello

I'm migrating to OEM 12 c (12.1.0.3.5). I built a completely new and repository management and the plan is to move a selection of objectives to this new SGO of the old system.

On a target is host (Redhat Linux 6) possible to install a second agent configured to load on the new OMS, while leaving the original agent facing up and running? It would be only temporary, and the original agent would stop after the target had been discovered and configured in the new OMS.

Is it possible to run two agents simultaneously on a single host?

Thank you

It is not recommended to run 2 versions of EM agents for a period of time, but it is possible.  Things to monitor and test:

  • port must be unique - if 11g use 3872, so you'll need to choose something else for 12 c
  • installation location must be unique
  • DB generated alerts (for example the tablespace) are actually stored in the Pb, then there may be an inconsistency between the 2 and the db if you start to change the thresholds, while the two officers are on the rise and running

Yet once, it is not recommended as a best practice because of the problems of threshold, so plan to 11 g stop agent as soon as possible.

  • Oracle Enterprise Manager (OEM) 12 c Cloud Control is broken after a reboot

    People,

    I use Oracle Enterprise Manager (OEM) 12 c Cloud Control version 12.1.0.3.  It was all work until we rebooted the box.

    Now, nothing is listening on the port 7801 more (by netstat), but if I put port 7302 instead in the browser's address bar, it'll take me actually to the OEM login page.  Once I'm connected, many things show that there are problems with communication between WHO and the agents.

    The shutdown process was not very successful and cleaning, shown below.  There was a lot of java still running process that I had to kill.

    This seems like a simple question, because we didn't change anything except adding memory to the box and restart.

    Is there anyone experiencing the same problem?  Is there any solution to this?

    Brian

    Brian,

    Can you access the console on https://oraaux1:7801 / em now?

    And, you are able to start the agent by running $AGENT_HOME/bin/emctl status agent?

    Regarding your initial post, is also the repository on the same host? If so, the problem could be due to the repository database was not entirely upwards when WHO launched on the reboot of the host system (gcstartup) startup script.

    When the SGC does not work as expected, you can take a look at SGD/monitoring of log files for clues. If necessary, please see:

  • How inegrate OID with OEM 12 c Cloud Control

    Hi all

    Is someone can you please tell me how I can integrate OID with OEM 12 c Cloud Control. As we integrate our OID with weblogic administration console, is it possible to integrate the control of cloud OEM with OID?

    Thanks in advance!

    Hello

    Please find the URL below:
    http://docs.Oracle.com/CD/E24628_01/doc.121/e24473/security.htm#BABGAGIJ

    Following article will provide you with information related to the integration of the OID:

    13.2.5 oracle Internet Directory (OID)

    You can implement an OID authentication scheme have Enterprise Manager to authenticate users against the OID.

    The emctl config auth oid on the WHO command creates an OracleInternetDirectoryAuthenticator type WebLogic authentication provider that uses the configuration specified by the command parameter values. All the configuration values specified not retain the default values. Tuning and modification of the OID advanced configuration settings is performed through the Console of Administration WebLogic Server and not the emctl config oid auth command.

    Prerequisites

    LDAP Directory Internet Oracle server is turned on.

    Run the oid emctl config auth on each SGD command.

    emctl config auth oid-ldap_host - - ldap_principal ldap_port [-ldap_credential ] [-sysman_pwd ] - user_base_dn - group_base_dn
    where:

    ldap_host: LDAP host name

    ldap_port: the LDAP port

    ldap_principal: the unique name (DN) of the user LDAP of the WebLogic Server should use to connect to the LDAP server.

    ldap_credential: password for the user specified by ldap_principal.

    user_base_dn: the basis of unique name (DN of the tree in the LDAP directory that contains the users).

    group_base_dn - the base distinguished name (DN of the tree in the LDAP directory that contains the groups).

    Example:

    emctl config auth oid-ldap_host "ldaphost" - ldap_port "3060-" ldap_principal "cn = sleep" - user_base_dn "cn = users, dc = us, dc = oracle, dc = com" - group_base_dn "cn = groups, dc = us, dc = oracle, dc = com" - ldap_credential "my_ldap_password" - sysman_pwd "my_sysman_password".
    Stop the SGD.

    emctl stop who-all

    Restart the SGD.

    emctl start SGD

    Note:
    For deployments of Enterprise Manager in several instances of the WHO, emctl config auth oid must be run on each SGD. Each MSO must be restarted so that the changes take effect.
    Test the Configuration of OIDS

    Use the WebLogic Server Console of Administration (tab users and groups) to check if the configuration of the OID is successful. To access this tab, select Home/summary of Security Realms/myrealm/users and groups. Tab users and groups, you will see the users and the groups showing the OID.

    A full individual membership, two computers simultaneously, using 2 different applications of CC. For example: I am editing/export in Premiere Pro on one, audio with hearing or graphics with Photoshop on the other. Is this OK and I will be able to access creative cloud of these two computers at the same time?

    Thank you! Christy

    Hi John,.

    There was some confusion on this subject at the launch of creative cloud. The EULA States that you can install it on two computers at once, however, you may not use the applications on those computers simultaneously. This is the case even when you are not in the same application. Sorry for the confusion.

    Thank you

  • Audit in two stages on the same device? !

    After upgrading to Mac OS Sierra the next thing happened:

    When I tried to sign in the community Apple with my Macbook Pro, I had a request of two steps and was invited to enter the 6 digit code that 'someone was trying to use my Apple ID to a place near me'... about 300 Km.

    I agreed, but the strange thing is that I got the 6 digit code on my Mac, where I had to type.

    Very easy process, but what is the meaning of this if I get the same code that I have to type on the same device? !

    I was a believer to receive on my iPhone or by SMS.

    There is something strange about this event?

    This scene reproduced whenever I tried to connect to the Apple community, until I checked "remember this browser.

    Tnxs.

    I arrived as well. My guess is that your mac is the only device approved for now, so the only option for apple is to send the code.

    If you go to ibutt settings in system preferences and click on account details, you can see which devices are approved under the devices tab. For me, it says my iphone is not usable as a trusted device, and I did bother to see if I can change this again, but I guess it can be done somehow.

    Edit: I just stumbled upon a thread discussing the same thing and found this answer, that solved the problem for me: Re: why Apple showed the authentication code to two factors on the same device that I connect to?

    I should add that if you operate the account using Pop then messages can be left on the server without any indication that they have been read. You define each customer to leave them on the server.

    However if you don't know what messages have been read, I know not how will you know which ones to delete and when to do it. Without active maintenance your server could quickly become full.
