Problems with OPMN from Companion CD (Oracle 10g R2 x86_64 RHEL4)

I have installed Oracle 10g DB R2 64bit on RHEL4 x86_64 (AMD64) and HTTP-Server from Companion CD
All works.
But after running opmn appears problems:
1. The system message to syslog: "ip_conntrack: table full, dropping packet"
2. 'netstat -a' displays me thousands TCP-session on localhost to port 6100 in TIME_WAIT state
And network services on my host more died than alive...
If I increase ip_conntrack kernel parameter, then network state alive. But the problem with TCP-sessions is not resolved.
Any ideas?
Thanks, and sory for my english :-)
P.S. I have RHEL4 without update 1, but with new kernel and patched binutils. Update of RHEL can resolve this problem?

Thank you!
The problem described in Metalink Doc-ID Note : 284602.1 is my case!
But this document applies to Oracle Net Services - Version: 10.1.0.2 to 10.1.0.3.
I have Version 10.2.0.1.0 and the problem apears again (with some symptoms are differ).

  • Problem with type 4 driver using oracle 10g

    HI,
    I am unable to establish a type 4 connection with oracle 10g.
    Specs:
    Driver used: OracleDriver that comes with the ojdbc14.jar along with oracle 10g
    JDK used: Tried using both j2sdk1.4.2 and using JDK 5.0
    JRE: Again, JRE that was shipped with j2sdk 1.4.2 and JRE 5.0
    OS: Windows XP sp2
    I am able to compile the following piece of code, so there is no classpath problem, etc.
    When I try to run the program, the exception thrown is "No Suitable Driver"
    There is no problem with the TNSListener, etc...even if all Oracle related services in 'services.msc' are Started/Stopped, the error remains.
    I am, however, able to establish the connection using type1 driver.
    Please Help!

  • Problem with global temporary table in Oracle 10g

    Hi All,
    I face a peculiar problem in Oracle 10g with respect to Global temporary table.
    Have Oracle 10g version in Production and 11g version in UAT.
    Table_
    create global temporary table TT_TEMPGPSMANUAL
      Col_1    VARCHAR2(50),
      Col_2    VARCHAR2(500),
      Col_3    VARCHAR2(50),
      Col_4    VARCHAR2(50),
      Col_5    VARCHAR2(15),
      Col_6    VARCHAR2(20),
      Col_7    VARCHAR2(250),
      Col_8    VARCHAR2(20),
      Col_9    VARCHAR2(15),
      Col_10   VARCHAR2(20),
      Flag     NUMBER,
      Col_11   INTEGER,
      Col_12   VARCHAR2(50)
    on commit preserve rows;So this should preserve the rows inserted into this table until the session ends.
    Have a webpage in front-end where in turn, it opens another page (session is carried through) and a few rows will be inserted to this table from the webpage (through a function) on submit and the current page will be closed.
    From the parent page, if I open the sub-page data inserted in the temporary table are held and displayed (another function to fetch the values in the Global Temp table).
    The Problem in Oracle 10g (Production) is, this is not happening properly. When I close and open the sub-page, not every time I get the data stored i.e if I close and open the page 10 times, atelast 4 times the data is missed in the page (I am not getting values from temp table) randomly.
    But this does not happen in UAT (which has Oracle 11g installed) as I get the data in the webpage consistently. After passing UAT, when we rolled out to Prod, getting this issue which we are unable to get what could be the reason.
    It is very hard to debug using GTT dynamically in prod. It takes time to get Oracle 11g installed in Prod.
    Can anyone suggest?

If you're just linking from one page to another, "parent" and "child" don't really make sense since page A links to page B and B links to A quite frequently.
    Assuming that you have to log in to access the site, it is likely that the two pages share the same middle tier application session. It is unlikely that the middle tier would hold the database session from the first request open waiting to see if the user eventually requested the second page. It is theoretically possible that you could code your middle tier this way but it is extremely unlikely that you would want to do so for a variety of reasons. So, when you say "would [the] session ... be changed", it is likely that the application session would be the same for both calls but that the database session would be different.

  • Problems with migrating from access to oracle

    OMWB has a few problems with upper and lower case letters, when i try to modify my old access DB OMWB cant find the new table in Oracle:
    (3011 The Microsoft Jet database engine could not find the object <name>. Make sure the object exists and that you spell its name and the path name correctly. )
    the problem is that it searching for AP_BILD.A990BILDER but the correct name is AP_BILD.a990Bilder
    when i recreate the table as AP_BILD.A990BILDER it worked.
    but i cant do that for almost 400 tables!
    any suggestion how to fix this?
    also have a problem when creating the trigger:
    OMWB puts the tablename into 2 double quotation marks each side (""name"") and of course it tells me something of a tablenamelength of NULL and it doesnt work
    working with release 9.2.0.1.0 of OMWB

    update: if i try to link the table from access directly it also cant find the table, but can find other tables (the others are in upper case).
    could it be a problem with the odbc driver? does it automatically look for upper case names?
    anyone know how to fix this?
    thanks in advance

  • Problems with connection from PHP to Oracle DB

    Hello,
    I have a Win2k3 Server with IIS 6.0 and PHP 5.1.2. and an Oracle Client 9i installed.
    Recently I tried to connect via PHP to the DB but it failed with the following message:
    "Warning: ocilogon() [function.ocilogon]: OCIEnvInit() failed. There is something wrong with your system - please check that ORACLE_HOME is set and points to the right directory in ...\php-skript\test\funk_test.php on line 54"
    So I started looking in the internet for help and found a lot, but nothing that solved my problem. I tried everything (I think):
    * Oracle Client 9i regular Client- environment vars in all variations
    * Oracle Client 10g Instant Client- all variations again
    * I tried to delete all spaces in the "tns.ora" after a hint in another PHP-forum
    * I looked in this forum and found some hints
    BUT: Nothing helped me to solve my problem.
    So I changed my PHP-version from 5.1.2 to 5.0.4 and I got a different failure:
    "[26-Apr-2006 17:58:15] PHP Warning: ocilogon() [<a href='function.ocilogon'>function.ocilogon</a>]: _oci_open_server: ˜Õ‚ in ...\php-skript\test\funk_test.php on line 56"
    This message is really strange, because it contains no information about the failure.
    Has ANYONE another hint for me?? I really don't know what I should do.

    Because it's IIS, I set the env vars manually. That means --> my computer/.../advanced/environment vars/etc.
    After every change, I rebootet the IIS Service. Problem consists.
    Let's have a look, if your links could help...
    ########## EDIT ##########
    Ok, your links WERE INDEED REALLY helpful!
    My problems were caused by missing access-rights.
    How to solve this problem:
    * reinstall your Oracle-client
    * inet-user needs now access rights for
    + "oracle"- folder
    + "oracle\bin"- folder
    + "tnsnames.ora"- file
    * set environment vars
    + NLS_LANG = AMERICAN
    + ORACLE_HOME = "C:\oracle\ora92"
    + TNS_ADMIN = "C:\oracle\ora92\network\ADMIN"
    * restart IIS
    Now it should work!!! THX for your help!

  • Licensed version and free download from OTN of Oracle 10g DB

    I had a doubt with any difference with the licensed version and free download from OTN of Oracle 10g DB. We had downloaded a free version of oracle 10g
    database from OTN and are using it in our live environment. It seems to be working fine. We are trying to get a licensed copy of Oracle 10g DB also but that may take sometime. So, my doubt is whether the free download from OTN should not create any problems in our live environment.
    I hope, my question is clear.
    Please, help in solving the doubt.
    regards

    Hello,
    There is no difference whether you download from OTN or get so called licensed copy of oracle software. It's free to download and free to use you are using for personal eduction purpose, but if you are using for commercial purpose then you should contact oracle sales for pricing but you can continue with the same software.

  • Problems with date in procedure on Oracle 11g

    Hi gurus,
    I have some problems with the date format on Oracle 11g.
    Let me explain the situation:
    When I am starting a request like
    select to_number(to_char(to_date('01.04.2009','dd.mm.yyyy'), 'yyyy'))
    from sys.dual
    I got as result 2009 as number.
    When I do the same in a procedure of a package like this
    my_year := to_number(to_char(to_date('01.04.2009','dd.mm.yyyy'), 'yyyy'));
    the variable my_year contains the value 9 instead of 2009.
    Can someone explain me what's going wrong?
    I have just tested with changing the environment variable nls_date_format for the session and for the complete database with no success.
    Regards,
    Björn

    Thank you all for your replies so far:
    @Alex: You are right, using your short script in sqlplus gives me also 2009 as result
    So, I am now posting the essential excerpts of the procedure because the whole one is to large:
    function insert_szrl (my_fremd_name varchar, my_elementadresse varchar,
    my_zeitstempel varchar, my_wert float,
    my_status varchar, my_zyklus varchar,
    my_offset integer,
    my_quelle varchar, my_nzm_daten integer) return integer is
    begin
    my_date := to_date (substr (my_zeitstempel, 1, 10), 'dd.mm.yyyy') + my_tageswechsel +1/24;
    if my_zyklus = 'mm' then
    my_zeitstempeldate := add_months(to_date(last_day(to_date(my_date, 'dd.mm.yyyy')), 'dd.mm.yyyy'),-1) +1 + (my_tageswechsel+1/24);
    my_days := to_date(last_day(to_date(my_date, 'dd.mm.yyyy')), 'dd.mm.yyyy') - add_months(to_date(last_day(to_date(my_date, 'dd.mm.yyyy')), 'dd.mm.yyyy'),-1);
    my_year := to_number(to_char(to_date(my_date,'dd.mm.yyyy'), 'yyyy'));
    ptime.umschalttage_tuned (my_year, my_ws, my_sw);
    end if;
    While debugging the complete procedure I see since the start only a date which looks like '01.04.2009 07:00:00'

  • Windows 8.1 Problem with games from windows store.

    I've got a problem with games from windows store. The installation is going well without any problems, however when I try to open it it's loading and then it turns off. The same problem happens when I try to use Games for Windows. I've use a sfc scan and
    it shows some errors but unfortunately it cannot fix them. Should I share the CBS log or find the solution somewhere else? I hope you help, best regards.

    Hi,
    According to my experience, the problem like store game app open failed probably caused by hardware driver. such as Audio and Graphic driver. So, first of all, please try to reinstall these two driver to fix this problem for test.
    In addition, for SFC scan failed problem, it can be caused by many reasons, I would suggest you use another command to fix your system for test.
    Dism /Online /Cleanup-Image /ScanHealth
    Also you can test SFC command in Windows 8.1 safe mode.
    Thirdly, if problem persists, please check Event Viewer, generally speaking, it would record the app open failed events.

    Thats the ugliest code I've seen in a while and may be hampering your abilities to debug it. No offense - you have to start somewhere - think of it as somewhat constructive criticism.
    However, I cannot find any place where this is happening. Its happening on line 193.
    Also, this only happens when you try to move certain pieces to certain squaresThat might be a clue. Try printing out the indexes before line 193 and see what happens. Maybe use a debugger to step through your code.
