How to configure the automatic height parameter in init.ora

Hi all

While in a meeting, I heard the other dba recommend putting auto tune the database. Because our database has performance problem, and we cannot identify the problem.

How configure you Auto-Tune in init.ora? I just thought that this is the default when you install 11g DB.


Thank you very much.

I don't really believe that you need optimize db/init.ora, it is the application of programs that always cause a performance problem. as far as I know.

I don't know how you separate 'tuning the database', of 'update the application. Of course, the database has ever of performance issues, if no request ever question him. But that does not translate a useful database.

Can you share me experience when tuning the init ora gave to solve your problem of performance? drastically.

I've seen many cases where to throw additional RAM to a problem (i.e. increasing the SGA_TARGET, PGA_AGGREGATE_TARGET, MEMORY_TARGET, etc.) generated significant performance improvements. Optimizer of various related settings can also have a significant impact on the performance of the applications. Which is not to say, of course, only a first not when confronted with a problem of performance should be to try to adjust the parameters of the system. When you have evidence of the monitoring of a particular process, however, that the system is starved of SGA, adding the SGA is a very useful thing.

  • How to configure the engine JMX parameter in the administrative process?

    Hi all

    I installed OBPM10gR3 on the WLS 10 gR 3 clusting shell. OBPM Motors started successfully.

    There is an administrator of the server running on localhost: 10101, a Manager running on localhost:10103 server, another server managed running on localhost:10105.

    I wonder how do I set the engine JMX configuration in the Administration process. What port? 10101 or 10103,10105? How about the credentials, weblogic as the default user?

    I'm appreciated you can share me the configuration engine JMX in weblogic clusting administration process. Thanks in advance.

    Best regards
    Bill

    See below for the settings you need:

    Port: (port of the managed server you chose above)

    Hi Majekho,

    Your domain name has decided to 99.245.xx.x. If you go to www.test.tzo.com from the location of the host, you must see this IP address. If these numbers are the same, then all with TZO works correctly. I guess that it is a simple problem with ports (80, 1024) is not open in the router and forwarded to the right internal IP address of the device (for example. 192.168.1.xxx).

    In addition, if you have a DSL, you will need to call your ISP and ask them to show you how to put your modem in "bridge mode". This will disable the firewall in the modem that blocks incoming connections even if you open ports in your router.
    In addition, during the test, it is best to test on your device remotely, this is due to a common problem called loopback with most routers. For more information about looping, take a look at:

    http://www.bleepingcomputer.com/tutorials/tutorial140.html

    Download updates but let me choose whether to install them - if you select this option, Windows will download the updates on your computer, but not install them automatically. If you want to install updates, then you must install them manually. You should only select this option if you have a reason to not install updates automatically. Only advanced users should use this option.

    Check for updates but let me choose whether to download and install them - if you select this option, you'll be alerted when there are new updates available for download and install. You can then choose to download and install the updates that you want. This option should really be reserved for people who know exactly which updates they need, or those who have little access to the Internet.

  • How to configure the settings of mail on HP Laserjet Enterprise 500 color MFP M575 printer/scanner?

    How to configure the settings of mail on HP Laserjet Enterprise 500 color MFP M575 printer/scanner?  The Office has 5 staff members each with ending with [email protected] for example e-mail addresses.  We have also created an email for option analysis as [email protected] (not sure if creating an e-mail address for the scan option is required).  We are not part of any domain, and there is no server in the office.  When you try to configure the email on the printer/scanner control panel it asks the host name.

    What host name that I can use?

    If you try to configure the browser by using the IP address of the printer, he asks as the SMTP server. The MS Outlook 2010 all our emails use mail.junior - albania.org incoming mail server and outgoing.  Other settings in MS Outlook 2010 are box My outgoing server (SMTP) requires authentication checked and use the same settings as my mail server entering selected.  On the Advanced tab: incoming server (Pop3): 110 (SSL encryption is not checked) and outgoing (SMTP) server: 465 use the type of encrypted connection (SSL) following.

    What server SMTP should I use in this case?
