  • Single Oracle Database repository to support SOA and OIM is it possible

    Hi, I'd like to install and configure SOA and OIM and would like to know if I can use one database as the repository to support SOA Suite install and OIM install ?
    In a development environment is it safe to install SOA Suite 11g and OIM 11g on the same server with all of its components? This is only for the development environment. Thanks

    Hi,
    I feel you can do it with single Oracle Database,check the below links:

  • Check "Problem: Oracle Database 10g Release 2 can only be installed in new

    Hi All
    Installing 10g software on AIX Box in /oracle/oraHome2,where oracle9i is already installed in /oracle/oraHome1 and oracle inventory is in /oracle/inventory
    In product specific prerequisite screen I am getting the
    check:Oracle Home incompatibilties is failed I am getting the error
    Check complete. The overall result of this check is: Passed
    =======================================================================
    Checking for Oracle Home incompatibilities ....
    Actual Result: Oracle9i Database 9.2.0.1.0
    Check complete. The overall result of this check is: Failed <<<<
    Problem: Oracle Database 10g Release 2 can only be installed in a new Oracle Home
    Recommendation: Choose a new Oracle Home for installing this product
    though I am installing it in different oracle homes why i am getting this error?
    Is it because 10g installation is picking the same oracle inventory /oracle/inventory
    do i need to make different oracle inventory for different oracle homes???????plz confirm..is thats the reason i am getting this error??????
    Thanks inadvance
    Gagan

    I figure out you are trying to install 10gR2 on top of an existing 9iR2 Oracle Home. This is corrected at the Path definition window. Most probably you just click on the <Next> and by default the 9iR2 Oracle Home was selected. You must define a new oracle home for the 10gR2 install.

  • Check Oracle database

    Windows Server 2008 64 bits - Oracle 11g 11.02.0
    I had a problem with an application yesterday morning.
    I had error ORA-7445 followed by some deadlocks and then the database went down.
    I restarted the database, and everything works fine. system and performance are ok.
    I've just finished the ADM1 course. The ADM2 will start in September. So I stil need to aquire some experience.
    I don't have any error in alert log file refering to block corruptions.
    The backups are working fine, although I know that backups don't really check this kind of problem.
    And at this moment, I don't have any user complaining about anything.
    In Microsoft SQL databases, I can run checkdb command in order to check if database is ok.
    I'd like to execute a similar command in oracle database in order to check if there is any corruption.
    I know there are some check logical commands available for Oracle.
    But I have no idea about how much they are going to affect my system.
    Could you please give me some suggestions based on your experience ?
    Thanks in advance,

  • How to check odi master repository exist in oracle database?

    Is there way to check the ODI master repository is exist in oracle database or any api to test that?
    Your help much appreciated.

    Thanks for you reply,
    That's fine, i think you aware of that, once open the topology manager "topology.bat", you can test the master repository, if you give any existing database user but its not master rep user, that throw exception "Master repository is not installed on this connection".
    I want know what are tables and data's are getting verified during the connection test.
    I think If you know regarding above my question, that will solve my problem.
    Thanks

  • Checking the health of Oracle database

  • Oracle Database Audit Health Check

    Hi Experts,
    I have been looking for checklist to perform the oracle database audit.
    what is the best practise to perfrom the database audit health check.
    Regards
    Mohammed. Abdul Muqeet

    Hi,
    What is it mean for Health Check, You mean you have audit enable in your database and you want to manage it. if so
    then you have to take care of Audit area at OS level and sys/aud$ table
    for Audit Area: you can schedule a job to clear that are time to time
    for sys.aud$: Move this table to non- system tablespace and moniter the uage. can purge the data if not required after taking the backup..

    go for patchset 9.2.0.8 and the latest minipatch (currently 9.2.0.8.10).
    deadlocks are normaly application specific and not database related. the ORA-000060 only indicates that the Oracle database prevents a deadlock (two or more transactions locking each other)

  • Oracle Database Migration Assistant for Unicode (DMU) is now available!

    Oracle Database Migration Assistant for Unicode (DMU) is a next-generation GUI migration tool to help you migrate your databases to the Unicode character set. It is free for customers with database support contracts. The DMU is built on the same GUI platform as SQL Developer and JDeveloper. It uses dedicated RDBMS functionality to scan and convert a database to AL32UTF8 (or to the deprecated UTF8, if needed for some reasons). For existing AL32UTF8 and UTF8 databases, it provides a validation mode to check if data is really encoded in UTF-8. Learn more about the tool on its OTN pages.
    There is a new Database Migration Assistant for Unicode. We encourage you to post all questions related to the tool and to the database character set migration process in general to that forum.
    Thanks,
    The DMU Development Team

    HI there!
    7.6.03 ? Why do you use outdated software for your migration.
    At least use 7.6.06 or 7.7.07 !
    About the performance topic - well, you've to figure out what the database is waiting for.
    Activate time measurement, activate the DBanalyzer with a short snapshot interval (say 120 or 60 seconds) and check what warnings you get.
    Also you should use the parameter check to make sure that you don't run into any setup-induced bottlenecks.
    Apart from these very basic prerequisites for the analysis of this issue, you may want to check
    SAP Note 1464560 FAQ: R3load on MaxDB
    Maybe you can use some of the performance features available in the current R3load versions.
    regards,
    Lars
    p.s.
    open a support message if you're not able to do the performance analysis yourself.

  • Can't mount oracle database on linux system

    This is same as previous posting just added
    e-mail and username info fo forum posting.
    I am not able to mount an Oracle database.
    I am new to Oracle and am working on an Oracle8i installation on an
    Intel Linux Suse 6.3 platform. I am using only one harddrive and am
    not using the 4 mount points as mentioned for efficiecy purposes in
    the Oracle documentation..I am using the installation cd from Oracle8i
    for Linux Starter Kit by Oracle Press. If anyone has this book they
    can refer to pages 41-44 for the examples I followed.
    As sysdba in sqplplus using the STARTUP command I can not Mount the
    database -step 2 of the 3 stage process (Start, Mount and Open the
    database) of opening an Oracle database.
    I show the errors I encountered when I did the first 2 of the 3 steps
    in the step-by-step mode (STARTUP NOMOUNT pfile=, ALTER DATABASE
    MOUNT) in the sqlplus session and alert log respectively with startup
    nomount and alter database mount for this sqlplus session.
    Additionally I show the init.ora file lines referring to control file
    which seem to be referred to by the sqlplus error messages and the
    alert.log file. Perhaps some can give me some advice as what I can try
    to fix this problem.
    At the end of this e-mail I added several questions I had in regard to the control

    It's probably not supported on RHEL5/Centos5/etc., but...
    You can get the installer to function using the following steps:
    - extract the cal_linux_*.tar.gz, and cd into the OracleCalendar_inst directory
    In there is the actual installer, cal_linux.
    - the cal_linux is shell script wrapped around some binary blobs. The installer's
    problem is that Oracle is setting the LD_ASSUME_KERNEL=2.2.5 environment
    variable, which is a mistake on RHEL5. You need to make it not set that variable,
    but you need to do so in a way that the size of the shell script does not change at all,
    and none of the binary blobs are impacted.
    - the approach I took was
    mv cal_linux cal_linux.BAK
    sed -e 's/LD_ASSUME_KERNEL=2.2.5/LD_ASSUME_KERNEL= /g' < cal_linux.BAK > cal_linux
    chmod a+rx cal_linux
    cal_linux -i gui
    Note: you must have exactly 5 spaces in the substitution part of the sed command, because you're replacing 5 characters (2.2.5), and the size of the shell script must not change.
    If you do that, the installer should run (one warning from awk still) and you should be able to install the product.

  • Retrieve data from a synonym in oracle database through db connect

    Hi Everyone,
    I have created certain synonym for some tables in oracle. I want to retrieve data from it through db connect but where through source system and then selecting database tables, only tables and views are available.
    Synonyms are not available to create data sources and retrieve the data from it. Why is it so. Is this a limitation of db connect.
    Can anyone please let me know about it.
    Thanks,
    Joshua.

    Hi,
    You want to import data from an external Oracle database into your BW 3.X. To do this, you can connect the external database to the BW 3.X release as a source system using the external database connect. BW 3.X here represents BW 3.0, BW 3.1 and BW 3.5 because in other (DB relevant) parts, all 3 versions are based on the same source code.
    General information
    The above function allows you to load data from an external Oracle database (not a BW database) into your BW 3.0 system.
    There may also be constellations which cannot be used directly through the DB Connect access. However, it should be possible to find an adequate, customer-specific solution for most of these scenarios.
    In such situations, the resulting work falls into the area of Consulting and cannot be handled via Support.
    Successful implementation of a connection requires corresponding expertise and experience in the use of the source database in the areas:
                    - Tools
                    - SQL syntax
                    - DB-specific functions
    Corresponding knowledge of the source application is also required to ensure that semantically relevant data arrives in the BW system.
    Procedure
    You should execute the following steps to connect the source system (Q) to the BW system (BW):
    Installing the client software on an BW application server
                         Of course, you only need to install the client software if you are using BW with a non-Oracle database.
                         Use the Oracle setup program on the database CD (runInstaller on Unix) to start the OracleInstaller. Follow the program instructions and the DB installation instructions to install the Oracle Client software on BW.
    Testing connection setup from BW to Q
                         After you install the client software on BW, try to set up a connection from BW to the server on Q. You may need to adjust the tnsnames.ora or sqlnet.ora files for this, to introduce the Oracle systems (to which contact should be made) to BW. You can test the connection by executing the command "tnsping QDB" on BW to check whether the client has established contact to the QDB database on the Q system.
    Creating a separate U user in Q
                         We recommend that you create a separate U user in Q for connection to BW. This means that authorization and administration questions can be solved centrally.
    Displaying data sources in Q for the U user
                         To provide U data for users other than U, you can create views on other user tables as user U:
                         CREATE OR REPLACE VIEW viewname AS
                           SELECT * FROM QDB.tablename
                         You may have to grant SELECT privileges to user U in the QDB schema:
                            GRANT select ON QDB.tablename TO U
                         Of course, you can also restrict or reformat data in the view arrangement (for example, change from internal date format into the SAP date format). JOIN operations using several tables are also available.
                         !!! Synonyms do not yet work!!!
                         Synonyms that you can create as described below are another option for providing a complete table for the user U:
                           CREATE SYNONYM synoname FOR QDB.tablename
                         !!! Synonyms do not (yet) work!!!
                         After you have displayed the require data for user U, you can simply use
                           SELECT * FROM <view or table>
                         on the Q system to check which data is returned.
                         You can now open a link to Q as user U in the BW system with SQLPLUS and check, using the same SELECT, whether this data is also seen in the Oracle client. If this is not the case, there is probably a connection problem.
    Creating a connection from BW to Q in BW
    Including data sources of user U user in Q in BW.
    Solution
    Supported BW, Basis and BW 3.0B database versions, Basis 6.20 Support Package 2 (or higher)
          Oracle 8.1 (or higher, see below)
    Possible problems
    - Synonyms do not (yet) work!
    Up to now, only tables and views have been used as data sources for the DB Connect from the R3 Basis. As soon as synonyms are also used in the Basis, you will be able to convert created views (or even replicated tables) to synonyms as a workaround.
    With Basis 6.40 at the earliest, therefore as of BW 3.5, you will also be able to use synonyms. Until then, the following will help:
      CREATE VIEW <view_on_synonym> AS SELECT * FROM <synonym>
    - The source DB must have at least the release version of the BW DB.
    Oracle only ensures the support of client-server links if the version of the client is not higher than that of the server. So if BW has Oracle version 8.1 and, as in the case of Dbconnect, is run as a client against the server of the source database, the source database must have at least release Oracle 8.1 or higher.
    Of course, you have the option to install the Oracle client software of a lower version and then use this for the DB connect. This is also the procedure used to work with a DB connect on external databases of other vendors.
    Furthermore, the implementation of the DBconnect function in BW uses SAP Basis functions. Specifications of Oracle 8.1 database catalogs are used here. The source database must therefore have at least Version 8.1.
    - Oracle Client Software Version
    If you want to connect from an Oracle BW DB to an Oracle source DB, for the DB connect you naturally use the client software that you already installed on each application server.
    If you want to connect from a non-Oracle BW DB to an Oracle source DB, check item 3 of note 521230 to see which Oracle client software version is released with your BW R3 kernel and use this version.
    - Date and time fields in Oracle and their conversion into SAP-compatible column formats
    Example with a DATE field:
    Since a SAP table does not have a DATE field (date values are NUMC(8) and time specifications are NUMC(6)), we will use the Oracle DBA_TABLES system table as an example.
        SQL> desc dba_tables;
    The Oracle DBA_TABLES system table has a LAST_ANALYZED field. This is a DATE type field and is recognized as a date field of 7 characters by DBA_CONNECT. However, the import does not work because the DATE is a 7-byte conglomerate of "...century, year, month, date, hour, minute and second." (extract from the Oracle documentation).
    To make this DATE field legible for DB connect, you must use the TO_CHAR function in a VIEW. This should display the following examples:
    SQL> select LAST_ANALYZED from dba_tables
          where table_name like 'RS%' and rownum < 10 ;
    The formatting used here is the default used implicitly by SQLPLUS.
    SQL> select  to_char(LAST_ANALYZED,'YYYYMMDD') as dat from dba_tables where table_name like 'RS%' and rownum < 10 ;
    The result now has the SAP compatible format YYYYMMDD and should be loaded correctly by the DB connect as a date.
    SQL> select  to_char(LAST_ANALYZED,'HH24MISS') as tim from dba_tables where table_name like 'RS%' and rownum < 10 ;
    The result now has the SAP compatible format HHMMSS and should be loaded correctly by the DB connect as a time.
    You can use the following example for more detailed experiments:
    SQL> select  to_char(
           TO_DATE('03-FEB-2001 04:05:06','DD-MON-YYYY HH24:MI:SS'),
           'YY-MM-DD HH24-MI-SS') as datim from dual;
    with the result:
      DATIM
      01-02-03 04-05-06
    When you create a VIEW and use the TO_CHAR function (or other functions), you should easily be able to avoid problems with the interpretation of date/time specifications (and other reformatting).
    Details about the functions and the formats are contained in the Oracle documentation.
    - Special characters
    A words that contain special characters can only be imported correctly if the code pages in BW and in the source system are identical. If the code pages are not the same, DB Connect can be used if the characters to be imported appear under the first 127 characters of the character set.
    The use of multibyte code pages in the source system for saving data using character sets with more than 256 characters (Kanji, Katakana, Hiragana, Korean, Chinese, Tagalog, Khmer, Arabic, Cherokee, and so on) can cause the characters to become corrupt.
    For questions concerning the code pages, also refer to the FAQ note 606359 and question/answer 19 that appears there.
