get the oracle environment variables by using the plsql code

Hey Geeks,

Can someone tell me how to get an environment variable Oracle (for example db_cache_size) from inside a plsql code or via a sql query block?

Thank you
Prabhu

You can query the parameter$ v.
http://download.Oracle.com/docs/CD/B19306_01/server.102/b14237/dynviews_2012.htm#REFRN30176

select * from v$parameter where name like '%cache%';

  • Is it possible to get the activation code of the older PC so that I can use it in my class?

    Original title: Activation of Windows 8.

    If there is some time I had windows 8 pro to use in my construction of future games. Not knowing I could install it on 1 computer (thought it would be at least 2) I installed it as a test on my desktop PC previos where it has not yet run properly cause it was an older model (and if you haven't used since then, cause I have a laptop with Windows7). But now my PC gaming is finished and I suddenly find I could activate only on 1 PC.

    So my question is. Is it possible to get the activation code of the older PCs (that I use even more, maybe even remove it) so that I can use it in my class? Or that the activation code and the money just went in the toilet?
    I could install Windows 7 to 2 different PC-s(didn't try more cause there was no need) with no problems and it wasen can't pack family, why is Windows 8 different? Sometimes errors occur.
    Ask cause I went all on buy the parts, I have no money to buy a new copy of windows 8.

    "I have Windows 8/8 Pro is installed on my PC." If I replace with another PC, can I install my copy of Windows 8 on my new PC until I remove it from the other? »

    Yes. The highest point is the one you mentioned: you must remove Windows 8 from your old computer before you activate on the new. In other words, you can have your copy of Windows 8 or Windows 8 Pro running on a single computer at a time.

    Another thing to keep in mind is that if you have installed an upgrade copy under license of Windows 8 on a computer and then you want to use it on another computer, the same 'upgrade' rules apply: you must have a previous version of Windows on the computer before you install Windows 8. You can ignore this rule, if you started with Windows 8.1

    Important: You can't "move" Windows 8 or Windows 8 Pro on another computer if your computer is pre-installed with Windows 8. Your copy of Windows 8 is what OEM licensed which means that you are allowed to use Windows 8 on the computer on which he came already installed on.

    "How many times can I reinstall Windows 8 on another computer? Assuming I follow the rule 'uninstall old installation', peux I keep installing Windows 8 on different computers? »

    There is no limit to the number of computers that you reinstall Windows 8 on as long as you follow the rules, that I discussed in the last question.
     

    Hi NeemeK,

    We appreciate the research you have done to find more information on this issue. The information you found were correct.

    OEM product key can only be used with the computer on which it is installed on.

    When the operating system is not active (uninstalled) in the old computer, you can install it on the new computer. This applies to any number of computers you use.

    If you get any errors, you can perform the activation of the phone.

  • Get the source code of a procedure for a huge package in oracle

    I have a package which, as methods of 40-50 in them, I would like to retrieve the source of one inside the package. is there a table where I can get this detail in the oracle database.


    I know there is an all_source table, which has the entire source code, but I want to only get the source code for a particular procedure.

    Thanks in advance.

    You have defined your procedure as provided

    procedure procedure_name...
    ...
    end procedure_name;
    

    and the procedure is not overloaded, you can try something as

    with
    first_line as
    (select line
       from all_source
      where instr(lower(text),'procedure '||lower(:procedure_name)) > 0
        and name = :package_name
        and type = 'PACKAGE BODY'
        and owner = :package_owner
    ),
    last_line as
    (select line
       from all_source
      where instr(lower(text),'end '||lower(:procedure_name)||';') > 0
        and name = :package_name
        and type = 'PACKAGE BODY'
        and owner = :package_owner
    ),
    select text
      from all_source
     where line between (select line from first_line)

In any case, I was unable to find such a CD. Disable my firewall has not changed the problem. I use Vista.
