OEM Access

Hello,
I have 4 instances up on a remote server. I am only able to reach the EM manager link for 1 of them through my local machine using Internet Explorer, which happens to be the first one that I created. I have checked all instances to make sure that emctl is up and running. I can connect to the initial instance that i set up just fine but for the other three I just get the "Internet Explorer cannot display webpage error. If I actually ssh into the database server(RHEL 5) and bring up the GNOME desktop and use mozilla, I can get to all 4. Any thoughts as to why I can't access the other three from my local machine?

Each OEM would be configured to run on its own port. Thus ..
1) are you specifiying the correct port for the OEM console you want to contact? (go to the server, set ORACLE_SID appropriately, and start the control with 'emctl status dbconsole', and notice the complete url, including port, that is reported)
2) Since you can connect to all four from the host machine, this pretty clearly suggests a firewall issue. Do you have an entry for each in your iptables?

    Again what limitation? Afraid to ask the password? Do not know how to override the password?
    Other than that: if some people don't want to tell you the perfstat password (maybe for valid reasons), do you think they will be happy when you start running your own queries against the v$ views (often quite expensive)
    or do you think you will gain more by cooperate with them. Other than that: if you want to run your own v$ queries why do you outsource writing them to this forum?

  • Limitation access

    Hi,
    My Question
    How to check OEM access the remote agent is unlimited
    If it not possible how to fix
    Plz give your suggestion
    Regards,
    Muthu

    You can limit access from the OMS to the Agent via https. If needed the OMS can be secure locked meaning that it only allows communication via https and will not allow unsecured trafic via http.
    In order to enable secured communication with the Agent, the Agent needs to be secured as wel.
    Is this what you mean?

  • SQL Monitoring using SQL Queries

    Hi
    I am using Oracle 10 g DB. I have an application which has Oracle as DB. Its a multiuser application. During the testing of one of the page we found that saving couple of records takes huge time (50-60 seconds). I dont have access to the logic written in application code to know which all queries gets executed when user click on save button.
    I know that there is SQL Monitoring available in OEM why which you can find out the queries which got executed and also the execution time for those queries.
    However I dont have OEM access.
    Can you please let me know teh set of queries which probably will use few of teh V$ data dictionary views and provide me the same details as generated in the Monitoting report generated by OEM ?
    I want to see all the queries which got executed in last defined time (say 10 mins, 1 hr etc) , same way as it is done in OEM and not just the last sql.
    TIA
    Regards
    Arun

    Hi,
    I recommend you to install STATSPACK - it's a free tool that can be used instead of the Automatic Workload Repository (that is used in OEM).
    This tool creates snapshots of V$ views in defined time period, so it enables you to see long runing queries in history.
    If I were you I would run SQL trace just before the problematic part and then stop it just as it has finished. It would be better to run trace only for the problematic session or module - not for the whole database. SQL trace generates a file with all the executed queries, explain plans, stats, ...
    In extreme case just create copy of v$sql before and after the problematic part and compare them (new sql_id, elapsed_time delta, ...)

  • How to Access Table Space Map in Oracle 10g OEM

    How and from where to Access Table Space Map in Oracle 10g OEM ??
    Thanks

    Hi,
    first of all, the online help system of grid control is outstanding. Just click on Help in the upper right corner and enter "Tablespace Extent Map" in the search form.
    Result:
    Show Tablespace Contents Page
    Each Oracle database is divided into one or more logical units called tablespaces. You can use Oracle Enterprise Manager to manage these tablespaces and create or modify the parameters for the tablespaces. Use the Tablespace property sheet to set general and storage information for the specified tablespace.
    Use the Show Tablespace Contents page to display the list of tablespace segments that comprise the existing tablespace. You can display Tablespace Extents by choosing Show Tablespace Extent Map at the bottom of the page. An extent is a logical unit of database storage space allocation made up of a number of contiguous data blocks. One or more extents in turn make up a segment. When the existing space in a segment is completely used, Oracle allocates a new extent for the segment.
    You can view segment extents by clicking on the link in the Extents column to display the Extents in Segments page.
    You can display the Show Tablespace Contents page by choosing Show Tablespace Contents from the command drop down list on the Tablespace property page, the Tablespace View page, or the Tablespace search results page.
    Note: Developers could only display the tablespace map to a maximum hard coded number of 30,000 extents. Tablespaces are often larger than that. If a tablespace is larger than 30,000 extents, the portion over that is displayed as Unmapped. To avoid exceeding the memory capacity of the tablespace map and to display the map without unmapped extents, use a search criteria displaying results of less than 30K extents.
    For an overview of tablespaces, see the "Overview of Tablespaces " chapter of the Oracle Database Concepts Guide.
    For more information about managing tablespaces, see the " Managing Tablespaces" chapter of the Oracle Database Administrators Guide.
    For more information about managing datafiles, see the " Managing Datafiles and Tempfiles" chapter of the Oracle Database Administrator's Guide.

  • How to access Data Guard option in Oracle 10g OEM

    Hi All,
    I have Oracle 10g ENTERPRISE EDITION on Unix envoirement. I want to setup logical standby Database through Data Guard technology. But when I brows through OEM I do not find Link for DATA GUARD????
    1) How to access Data Guard option from oracle 10g OEM.
    2) Does It come with Enterprise Edition OR I have to install it separately.
    Regards,
    Darshan

    I am managing almost everything through EM Grid Control. It is easy to setup and configure.
    Anyways, if you have read the documentation on
    Oracle® Data Guard Concepts and Administration and setup your environment accordingly then you should not have any problems. Atleast I can assure you that your production database will not be affected by it.
    Just make sure that you follow each step and read thoroughly. If you have spare machines then you can test and record your configuration before performing it on your production db. This link will provide you with the information on DataGuard.
    http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14239/concepts.htm
    If you think that way then you will never be able to do any new stuff since you will always fear that something might go wrong. Go ahead pal, try it on test machines and you will know that it is not that difficult.
    There are real experts who help people like us in this forum and I know that they are doing a pretty good job.
    All the best.

  • Thru OEM get list of queries and their schemas that accessed my objects

    Hi,
    I have a list of objects on my schema and i need to track the list of sql queries by different users that accessed by object during this time period.
    i haven't enabled any auditing yet.
    is there any way i can get that list of queries and their schemas that accessed those particular objects during a particular time period through OEM.
    Can someone guide me please.
    Thanks in advance.
    Philip.

    create a name property in your class and assign a name property to your instances (either in the contructor) and/or using getters/setters.  (you'll need a getter anyway.)

  • How to provide access to login oem to another user except sysman?

    Hi,
    i have installed OracleGrid 10.2.0.3 in windows 2003 server and configuared 10 servers and 15 databases in oem. i created one user in oem repository database. that user should access only two databases through oem. how configuare this?
    Thanks,

    You should not create a super administrator to meet your requirement. So, uncheck the 'super administrator' and choose only the targets which you need to provide access. Follow all the six steps of user creation. You can also provide a full access or just view only.

  • The Character is rough-and-tumble accessing discoverer via OEM

    Dear all.
    I'm new for ora9ias. I have some install questions.
    In the first machine, I only installed Oracle9iAS Infrastructure. The product language included simple chinese and english. and I selected the default character set.
    In the second machine, i installed oracle9ias.
    Then I successfully accessed the OEM like this website http://sec.mach.com:1810.
    But when i access the discoverer from the system groupware, i find that the
    character is rough-and-tumble except english.
    Must i use the UTF8 as character set in Infrastructure? if yes, can i change the
    character set without reinstalling Infrastructure.
    Please give me the answer. thank you.

    Hi
    You cannot embed the password on the java command line. This was determined to be a security breach because the password would have been in plain view. In order to make a URL work you need to be working with the full application server and be using either private or public connections, ideally with SSO enabled.
    All you do is run the report as usual from within Viewer when connected as the user you want to be connected as. You can then copy the URL from the address bar at the top of your browser and paste this into a new browser. If a public connection is being used without SSO the report will execute. If SSO is enabled then SSO authentication is required. If a private connection is being used without SSO then the password will be prompted, whereas if a private connection is being used and you are using SSO then the password will be remembered by SSO and supplied for the user.
    I hope this helps
    Best wishes

  • Accessing an ASM Instance via OEM

    Gaining access to an ASM-managed database instance via Enterprise manager is done in the same way as accessing a "normal" RDBMS database: http://<host>:<port>/em/
    Is it also possible to access the ASM instance itself via the OEM? If so, what's the typical URL/port for access?
    I have not seen this documented, and I wonder if it's possible to access the ASM instance via OEM after all, or can you view/manage ASM instance information only via SQL statements.
    Thank you.
    John

    That makes perfect sense... nufortunately, I'm sitll confused. I just found a series of screen shots that explicitly say "Database Control", and the home page shows the "+asm" link I mentioned in my earlier post. What's more: these screen shots are directly from Oracle! Their "Oracle By Example" series has an entry called "Creating and Managing ASM Disk Groups", and the section called "Viewing Disk Groups" has a series of shots that clearly shows first an ASM-managed instance, and then the ASM instance itself, being directly managed by Database Control.
    I wish someone from Oracle, or someone who has seen this in action, would chime in and let us know how it works!
    Thanks.

  • Can't access personal data on OEM partition

    My laptop comes with a SSD and a normal HDD. One fine day I switch on my computer and it says 'Insert bootable device' I thought that my SSD had crashed and since it assumed it had the OS I wasn't able to boot into Windows. So I removed the normal HDD put it into an enclosure to retreive my personal data. The HDD (750 GB) has three partitions, one is a Lenovo partition (29.30 GB) with applications and drivers and there are two OEM partitions (14.75 GB and 655 GB). I presume all my data is in the 655 GB OEM partition and I can't seem to access it. How can I access the data on OEM partition and recover my personal files ? Any advice/suggestion would be welcome. 

    Hi
    I think that the os might be on the hdd(655gb) partition and as it has been marked as a oem partition, bios is not able to access the boot files on the c drive. Since data comes first, use ptedit32.exe to change the partition type of 655gb partition to 07 from 12 and then assign it c you might have to reboot and then you could copy the data from the hdd and keeping the partition unhidden, try to boot from it in laptop.
