Functions: Oracle VM Manager vs. Grid Control Oracle VM Management Update

Hello guys,
i have seen both tools .. and i have to say that some really basic functions are missing in the Oracle VM management addon for Grid Control 10.2.0.5 .. just some examples:
- Renaming virtual machines (because of the prefix syntax is not very useful)
- Adding ISOs as CD/DVD after removing them one from the profile (until now you need to know the whole path to the DVD, even if the ISO is registered in the repository)
- Renaming image files (for example the disks of the VMs .. this would be very helpful in case of cloning machines)
- List the VNC port for the running VMs
All these features are available under the VM Manager (except the renaming file part) ... do you know when this will be implemented or is the Oracle VM management update already "finished" in its functions.
Regards

Hi,
You can manage your Oracle VM environment using Oracle Enterprise Manager 12c. Using Oracle Enterprise Manager 12c you can discover Oracle VM Servers, discover storage servers and file systems, create and edit server pools, set up networks and create storage repositories.
for more information, look at this URL.
I hope this can help you

Monitoring oracle database from OEM 12c grid control

Hi,
I am using OEM 12c grid control to analysis various server's performance. The application database in oracle database v11g. Is there any problem if i add database on oem to monitor? To be more clear, If it creates any conflict between database's em and oem's em when i want to deploy em agent on database ? Is it necessary to remove database's EM before installing oem agent on it?

Oracle Connection Manager

Hi,
i'm having a problem configuring Oracle Connection Manager. It does start the instance of connection manager
Summary of my environment is
10g Application server and infrastructure machine OS: Windows 2003
9i Database Server: Windows 2003
Client : Java Applet
JDBC driver type : THIN
Installed: 10g Infra first and then 10g midiier(portal and wireless) in seperate oracle homes on the same machine. Eveything is up and running as i was able to login seperately in infra and midtier enterprise managers.
Final Goal : Trying to connect to an Oracle 9i database on a differnt machine than the appserver using an applet, thin drivers and Oracle Connection Manager
Problem : Connection manager instance not started however cmanADMIn service started.
CMCTL:CMAN_oracle9-app> administer cmanOracleAS
Current instance cmanOracleAS is not yet started
Connections refer to (address=(protocol=tcp)(host=10.10.1.101)(port=1610)).
The command completed successfully.

Steps done to configure Oracle Connection manager
1. Copied 4 .exe (CMADMIN, CMCTL,CMGW,CMMIGR) files to bin folder of Appserver or midtier's main ORACLE_HOME/BIN folder.
2) created a cman.ora file and copied in appservers /NETWORK/ADMIN directory
3) On cammand prompt type CMCTL...ADMINISTER cman_OracleAS where cman_OracleAS is the name of cman instance used in cman.ora file.

Certificates in lieu of Oracle connection Manager for our Applets -- Help!!

I support an application named IDEA out of New York. The IDEA application is an INTRANET application for use within our company Firewall.
Currently, the IDEA application's front end resides on a Windows 2000 Server running IIS 5 and JRun 3.0. The back-end runs on Oracle 8.1.7 database on a UNIX Database Hosting Utility (DHU). Our applets communicate with the back-end database using Oracle Connection Manager that is installed on the Web Host.
We are trying to migrate to the DWeb environment (Linux cluster). The linux cluster is running Apache Tomcat. We have been told that installing Oracle connection manager is not a viable solution (our company does not support it). Because of this our applets cannot communicate with our database. Below is a brief description of this limitation and also the work-around.
====================================================================================================================================================
Connecting to the Database through the Applet
The most common task of an applet using the JDBC driver is to connect to and query a database. Because of applet security restrictions, unless particular steps are taken an applet can open TCP/IP sockets only to the host from which it was downloaded (this is the host on which the Web server is running). This means that without these steps, your applet can connect only to a database that is running on the same host as the Web server.
If your database and Web server are running on the same host, then there is no issue and no special steps are required. You can connect to the database as you would from an application.
As with connecting from an application, there are two ways in which you can specify the connection information to the driver. You can provide it in the form of host:port:sid or in the form of a TNS keyword-value syntax.
For example, if the database to which you want to connect resides on host prodHost, at port 1521, and SID ORCL, and you want to connect with user name scott with password tiger, then use either of the two following connect strings:
using host:port:sid syntax:
String connString="jdbc:oracle:thin:@prodHost:1521:ORCL";
conn = DriverManager.getConnection(connString, "scott", "tiger");
using TNS keyword-value syntax:
String connString = "jdbc:oracle:thin:@(description=(address_list=
(address=(protocol=tcp)(port=1521)(host=prodHost)))
(connect_data=(sid=ORCL)))";
conn = DriverManager.getConnection(connString, "scott", "tiger");
If you use the TNS keyword-value pair to specify the connection information to the JDBC Thin driver, then you must declare the protocol as TCP.
However, a Web server and an Oracle database server both require many resources; you seldom find both servers running on the same machine. Usually, your applet connects to a database on a host other than the one on which the Web server runs. There are two possible ways in which you can work around the security restriction:
You can connect to the database by using the Oracle8 Connection Manager.
or:
You can use a signed applet to connect to the database directly.
These options are discussed in the next section, "Connecting to a Database on a Different Host Than the Web Server".
Connecting to a Database on a Different Host Than the Web Server
If you are connecting to a database on a host other than the one on which the Web server is running, then you must overcome applet security restrictions. You can do this by using either the Oracle8 Connection Manager or signed applets. ====================================================================================================================================================
It was suggested that we implement signed applets (it is our only alternative at this time). This is where, hopefully, you can help me. We are unfamiliar with using certificates and signing applets. We need to obtain certificates that will allow our applets to connect to our oracle database on the DHU. What kind of certificates do we use? Are their coding examples of how to use these certificates? We have a CA within our company but they cannot tell us what kind of certificates we need. How many certificates do we need? Do we install any certificates on the backend database server? Any information would be greatly appreciated. We are basically trying to get our applet to work outside the sandbox by establishing a connection to the database server.Thanks in advance for your time.

These options are discussed in the next section, "Connecting to a Database on a Different Host Than the Web Server".
If you want to connect to the database from the applet there is a third option.
Since this is an intranet application you have control over the desktops using this
application. In our company the jre ignores signed applets (as it should) because
it gives control to the user to run potentially harmfull applets from the Internet.
The way to dish out special privileges to applets is the policy, put a policy file on
you intranet and have the jre use it by specifying its URL in the java.security.
Here is some more info about security configuration of the jre:

How to install oracle connection manager on solaris 10

I have installed oracle application server 10.1.2 on solaris 10. How do i install oracle connection manager utility.
My end goal is to use applets/jdbc.
Thanks

Thank you Zettabyte!!
Folks, network printers should NOT BE configured like this:
lpadmin -p somequeue -s someprinter
that creates a remote style queue and puts all the I/O and processing capability on the basic LPD listener present on network printer interfaces. This will cause problems down the road, not to mention that you cannot control access, get any logging, filter content, or control banner pages.
Network printers should use any software (or PPD file) supplied by the vendor over the basic lpadmin/netstandard config.
You can install CUPS, but Oracle won't support it until it's part of the OS (S11, apparently).
The "System Administration Guide: Solaris Printing" is highly recommended for those administering printers on Solaris.

* A specfic address in SRC or DST for a rule in the rule list must be resolvable(Try ip address range as a workaround and see the enhancement request 6125025)
* Windows: Ensure the ORA_DBA group is present and O/S user starting CMAN is in the group
* Windows: Ensure any firewall is not blocking Oracle from using Network
All help are appreciated!

DataDirect and Oracle Connection Manager

Quick Question - Has anyone made the Plumtree Portal running on Oracle using the built in DataDirect drivers work with an infrastructure that uses Oracle Connection Manager (OCM).
Due to security and performance reasons, using Oracle Connection Manager is needed to communicate accross firewalls.
Ive already followed up with DataDirect, they dont support it currently. Plumtree Support doesnt seem to think it will work (im guessing there right).
If anyones got any insight, it be appreciated.

please send configuration file of cman.ora, listener.ora

A question about Manage Observer by Grid Control

Hello everybody
My Enviroment:
Primary Database:
Single Instance 11.1.0.7
S.O.: SLES 10 SP2 x86_64
Standby Database:
Single Instance
S.O.: SLES 10 SP2 x86_64
Observer:
Oracle Client Administrator 11gR1 x86_64
S.O.: SLES 10 SP2 x86_64
Reading Oracle Documentation, I found at Oracle Data Guard Documentation that I have to install the full Oracle Database 10g software kit to manage observer by Enterprise Manager.
My question is I have to install Oracle Database 10g Software to manage observer by Oracle Grid Control 11g??
Thanks a lot

Thanks CKPT for awnsering.
Yes I know that I have to deploy Observer at diferent server.
So I don't have to install Oracle Database Software to manage Observer by Grid Control 11g. That 's was looking for.
Thanks a lot.May be here small confusion. I mean to say of course you have to install ORACLE_HOME(client) but no need to install/push from GRID.
You can perform installation at system level instead from GRID. Hope this clears.

Add rule to oracle connection manager

I need to add a rule in my oracle connection manager.
Now I do not use rule:
(rule_list=

(src=*)(dst=dbxx-int.dbc.cineca.it)(srv=service_name2_ext)(act=accept)
(action_list=(aut=off)(moct=0)(mct=0)(mit=0)(conn_stats=on))
Since my two service_name end with ext can I use a single rule like this:
I can add a rule like this:

this forum is commonly used to connect from Oracle databases to foreign databases using Oracle's gateway product. A connection manager can't be used here. You might ask that question in the generic database forum:

How to delete a management agent from grid control completely?

I have installed oem grid control 10.2.0.4.0 on single host(oemlinux.oracle.com), and I removed agent10g, and reinstall a new management agent into a new location, but when I wanted to add a weblogic server to monitor, I got error as below:
More than one Enterprise Manager Agent was found for the host.oemlinux.oracle.com
I found there were 2 agents in em console, how to delete the old agent from em console,anybody can help me?

Click on the All targets tab, delete the agent.
Then confirm that the delete is in fact happening.
Click Setup, Management & Services Repository tab.
Deleted Targets link.
Time Deleted Completed must have a date in there...
If all that fails - do a quick search - I posted the sql you can run against the repository to wipe it clean of an agent :-)
Not too that if you are removing the O/S software - you need to use the runinstaller to remove the Oracle Home from the inventory.
If you don't do this - future auto installs using the agentDownload script of the agent will fail.

Trying to monitor my sql servers in OEM Grid Control

Hello,
I have Oracle 10g OEM and I want to start monitoring my sql server databases. I've got the plug-in all setup but when it displays under my "Databases" it shows and status "down". My sql server host is running, listener running, and database is up but when I try to "configure" it gives the "Failed to connect to the database: Io exception: Connection reset The Connect Descriptor...." error. Can someone please help??? I would like to know....
1) under the monitor user name is says "dbsnmp" so do I have to create a dbsnmp user on the sql database side?
2) do I keep the same port number (1521) or do I put what the sql server db is listening on (1433)?????? - for the configuration in OEM
3) If i go to the "host" under "targets" it shows that the agent is "up" but the database instance is "down and the listener is "up.
Listening Endpoints Summary...

Welcome to the forums !
Not sure what this has to do with database upgrades (the topic of this forum), but pl confirm that you have followed all of the steps in MOS Doc 359413.1 (How To Download and Deploy Microsoft SQL Server Plug-in To Monitor SQL Server Targets From Grid Control )

How to monitor RAC services and nodeapps in Grid Control

Hi,
I have created a number of RAC service names such as GL on a 2-node RAC and would like to use Grid control 10.2.0.2 to monitor the availability of those services and nodeapps. I was not able to find anything in Grid Control that would allow me to configure that. What are being monitored now are the listeners, database instances and nodes. Would it be possible to monitor more than just the RAC listeners, instances and nodes?
thanks.

I don´t think that there is an out-of-the-box metric. However, CRS monitors your services and Grid Control monitors CRS errors. If you need more granular monitoring, I have 2 suggestions:
1) user callouts:
[http://download.oracle.com/docs/cd/B28359_01/rac.111/b28254/hafeats.htm#RACAD7133]
2) extending oracle enterprise manager
I have written a paper on how to extend oem at [http://www.ora-solutions.net/web/papers/]
"Extending Oracle Enterprise Manager to collect HP-UX glance data"
You can follow the instructions to build a new target type called "RAC_SERVICE" and add your serivces as targets, e.g. S_BATCH, S_ONLINE, S_HR.

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 ?
