Mininum resources for Oracle VM

Hi,
I want to know the bare minimum hardware requirement for Oracle VM setup.
1) Oracle VM server: It's mentioned in Server Installation guide that, dual core CPU and at least 1GB memory is required. Can we install oracle VM server with 512MB memory?
2) Oracle VM manager: Is it mandatory or optional component of oracle VM setup?
Many Thanks,
Neeraj

AVI, or other knowledgeable folks, I was wondering about the following:
HP 6554 with Intel Quad-core E6600 chip and 5 GB of RAM??
I know that should be sufficient if I dedicate the entire machine to OVM server. BUT I want to partiton it to run Windows natively - the current partition - and OVM server. I also may want a native Ubuntu or Fedora partition. The drive is 700 GB so space isn't an issue.
I have 2 major concerns...
-- Can I install OVM server on a 2nd or 3rd partition?? If not, can I use the 1st partition and then install other OSes afterward??
-- I realize this also asks about boot loaders
-- The reference material seems to require Intel VT extensions for HW virtualization. Would you know if the E6600 has these??

  • Minimum resources for Oracle Application Express

    Hi,
    I'm new to the forum, and a bit confuse here trying to find an answer to what supposedly is a simple question:
    What kind of resources do I have to have to develop and deploy screens with Oracle Application Express?
    The scenario:
    I have this Oracle application all created in forms that we are planning to give to our customers in a web based.
    I'm looking for options to convert it and many forums are talking about how easy and inexpensive (free) the Oracle Applications Express is.
    Then, talking with my main developer, he told me that in order to use it, the client need to spend quite a while in IAS (Oracle's Internet Application Server) and/or have to have the Enterprise version.
    I'm looking for white papers on that and could not find any corroboration, but just texts telling that it's free and easy to use.
    Any one can point me to the right directions on this issue?
    Just want to know what exaclty do I need in order to use (creating and deploying) the Applications Express.
    Right now I have Standar Edition 10q as well as my client
    THank you

    If you want to develop an intranet web application, the HTTP server that comes with Standard Edition 10q would do. However, if you are thinking of it as an internet application then you better separate DB and web server. In that case you need to have either Oracle HTTP Server or Oracle Application Express Listener. Oracle HTTP server requires a license and usually bundled with DB or an Application Server. I believe Oracle Application Server is no longer being offered/available instead web logic server is made available. The basic edition of web logic would do as all you require is Oracle HTTP Server to broker the requestes between the web and the database. As far as I know, Oracle HTTP server is not being offered standalone. As mentioned above the other alternative is Oracle Application Express Listener but requires one of the J2EE complaint web servers like web logic, Glassfish, OC4J or TOMCAT.
    Hope this helps!

  • Resource for Oracle 11g xe

    Hello,
    I am looking for free study material to learn 11g xe. I am a beginner in 11g but I had Oracle DBA 8i Certification. Will someone help me?

    Hello,
    a good starter would always be the [url http://download.oracle.com/docs/cd/E17781_01/index.htm]XE Documentation Library, especially the [url http://download.oracle.com/docs/cd/E17781_01/server.112/e18804/toc.htm]2 Day DBA. The latter one will probably not take you two days because you already know Oracle concepts, but it might be a good idea to fresh up and see what changed since the last time you studied...
    Depending on your focus, there might be other resources to point out. A good place to search for input is the [url http://apex.oracle.com/pls/apex/f?p=44785:2:5631230890156303:FORCE_QUERY::2:P2_GROUP_ID:1000]Oracle Learning Library.

  • How can i give more resource for oracle user

    hello
    i have a database user
    i want to give him more power resource from
    others

    You want to allocated more CPU and memory to users of the database? Or to the database processes in general?
    Perhaps you should rewind a bit here and explain what (why) you think you need to add resources to something ... then we can try to solve your problem, instead of trying to fix your solution.

  • Setting Resource limits for Oracle user in 11gR2

    HI Friends,
    I am using Oracle Database 11g R2 on windows.
    My Application connects to the database using a schema (user1). Some times the application user sessions makes the Database usage / CPU/ IO high and affecting the performance of the Database.
    I would like to set some Limits on the Resource usage (Database and System resources) for those Application user schema (user1) to avoid the bottleneck on the Database and Server without affecting the usage of the Application on Transactions.
    How can i achieve it?

  • Embedded License Resource Kit for Oracle Application Server 10g

    Hi,
    I work for a company and we are an Oracle partner. We would like to deliver our flagship product with Oracle Database and Application Server (10g) embedded.
    According to an Oracle press release back in october 2003, Embedded License Resource Kits for Oracle Database and Oracle Application Server are available through the Oracle Partner Network (http://www.oracle.com/corporate/press/2484668.html)
    I found a kit for Oracle Database through OPN but was not able to find one for Oracle Application Server 10g.
    Does such a kit still exist for Oracle Application Server, and if yes where can I download it?

    Go to MyOracleSupport/Metalink.
    Click patches and Updates on the top left bar. Download the patches.
    Each patch comes with its readme.txt. Do read it. It shows you how to install the patch. it also gives syntax with example for various scenarios of how to install it, or remove a patch either. In most of the patches, Installing a patch again does not hurt your system.
    It's a good practice to keep db inventory clean before attempting to install the patch because otherwise the patch installation will fail.
    hope that helps!

  • SUN  CLUSTER RESOURCE FOR LEGATO CLIENT (LGTO.CLNT) in Oracle database

    hi everyone
    I am tryinig to create a LGTO.clnt resource in oracle-rg resource group in SUN CLUSTER 3.2 with the following commands
    clresource create -g resource_group_name -t LGTO.clnt \
    -x clientname=virtual_hostname -x owned_paths=pathname_1,
    pathname_2[,...] resource_name
    I just need to know what is value of Owned_Paths variable in the above commnad?
    or what PATH it is reffering to ( $ORACLE_HOME or Global devices path ...etc) ?

    Hello,
    The Owned_Paths parameter are the paths (or mountpoints) the legato client will be able to backup from.
    To configure a legato client in the Networker console (and to be managed as a cluster client) you need to declare the in the Owned_Paths the paths you want to save.
    The savesets paths can be a directory under the Owned_Paths.

  • Need help for learning how to develop interfaces for Oracle R12 EBS

    Hi all,
    I need to learn how to create interfaces in PL/SQL for Oracle R12 EBS Financials. I cannot find a good starting point for the documentation and examples to help me get started in this area. Would appreciate tips
    for this area.

    Hi,
    What kind of interfaces you are planning to develop?
    Oracle already provides list of APIs that can be used (in R12, it is responsibility).
    Oracle Integration Repository Documentation Resources Release 12 [ID 396116.1]
    Oracle Integration Repository
    http://irep.oracle.com/index.html
    If those APIs do not satisfy your requirements, you can refer to "Oracle Applications Developer" guide as well as SQL-PL/SQL guides.
    Applications Releases 11i and 12
    http://www.oracle.com/technetwork/documentation/applications-167706.html

  • How can I use custom WLST commands for Oracle SOA Suite in Weblogic

    Hi There,
    I'm trying to view and search the weblogic log files using WLST on a Solaris/Unix system.
    I have come across this "custom WLST commands for Oracle SOA Suite" and thought of using the custom logging commands to get my task done.
    However, my WLST shell is not recognizing the commands and giving me the NameError!
    wls:/devDomain1/domainRuntime> listLogs()
    Traceback (innermost last):
    File "<console>", line 1, in ?
    NameError: listLogs
    I tried the commands listLogs, displayLogs, getLogLevel & setLogLevel but in vain!
    I have followed the instructions as per the oracle recommendation of using Custom WLST commands (http://docs.oracle.com/cd/E29597_01/core.1111/e10105/getstart.htm#ASADM10692) as below
    - Launched the WLST shell from Oracle Home.
    cd ORACLE_HOME/common/bin
    ./wlst.sh
    - Tried to run the listLogs command from domainRuntime()
    I would like to know if I need to import any additional libraries to run the custom WLST commands for Oracle SOA Suite in my WLST shell?
    I have only weblogic 10.3.1 server installed on my Solaris 10 machine on which I have deployed the OSB application software.
    There is no SOA Suite installed.
    Or is there any other way I can browse the Server Log file and get the list of log messages? Basically I would like to use this feature in my script to customize it according to my requirement of listing specific error logs which I can work it out if I know how to make these commands work.
    Please advise if this is possible and how?
    Cheers.
    Satish

    I have tried on my OSB installation (no SOA Suite here), the command listLogs() works (I was in online mode, after a connect), and the classpath is:

  • OIM 9.1.0.2 - Weblogic JDBC Multi Data Sources for Oracle RAC

    Does OIM OIM 9.1.0.2 BP07 support Weblogic JDBC Multi Data Sources (Services>JDBC>Multi Data Sources) for Oracle RAC instead of inserting the "Oracle RAC JDBC URL" on JDBC Data Sources for xlDS and xlXADS (Services>JDBC>Data Sources> xlDS|xlXADS > Connection Poll> URL) ?
    If yes, is there are any other modifications that need to be made on OIM, or just changing the data sources?

    Yes, it's supported. You install against one instance directly of the Rac Server. Then you update the config.xml file and the jdbc resource in your weblogic server with the full rac address. It is documented for installation against RAC. http://docs.oracle.com/cd/E14049_01/doc.9101/e14047/database.htm#insertedID2

  • Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

    Hi all,
    Need some help from all out there
    In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
    ora-29701 *Unable to connect to Cluster Manager*
    during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
    We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesn’t work anymore when the server is rebooted.
    Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.
    Bug No. 4262155
    Filed 25-MAR-2005 Updated 11-APR-2005
    Product Oracle Server - Enterprise Edition Product Version 9.2.0.6.0

    Problem statement:
    ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
    *** 03/25/05 07:32 am ***
    TAR:
    PROBLEM:
    Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
    While creating the database, customer receives following error:
         ORA-29701: unable to connect to Cluster Manager
    However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
    DIAGNOSTIC ANALYSIS:
    It seems that the problem is with libskgxn9.so shared library.
    For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
    installActions2005-03-22_03-44-42PM.log:,
    [libskgxn9.so->%ORACLE_HOME%/lib/libskgxn9.so 7933 plats=1=>[46]langs=1=> en,fr,ar,bn,pt_BR,bg,fr_CA,ca,hr,cs,da,nl,ar_EG,en_GB,et,fi,de,el,iw,hu,is,in, it,ja,ko,es,lv,lt,ms,es_MX,no,pl,pt,ro,ru,zh_CN,sk,sl,es_ES,sv,th,zh_TW, tr,uk,vi]]
    installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]]
    For 9.2.0.4 -> 9.2.0.6, install log shows:
    installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
    This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
    ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
    WORKAROUND:
    Customer is using the following workaround:
    cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

    Hi,
    We are also trying to install 11.2.0.2 Grid infrastructure for Oracle RAC One Node on AIX 6.1. We did a POC in our lab environment and after much struggle got that working. Now we are building 4 clusters in the production environment and the first cluster installation failed while running root.sh on node2. We already have a Sev1 ticket open with Oracle Support but have not heard anything.
    Here is root.sh output from node2. The two node names are p01dou416 and p01dou417.
    CRS-4402: The CSS daemon was started in exclusive mode but found an active CSS daemon on node p01dou416, number 1, and is terminating
    An active cluster was found during exclusive startup, restarting to join the cluster

  • DATABASE RESOURCE MANAGER ( ORACLE 8I NEW FEATURE )

    제품 : ORACLE SERVER
    작성날짜 : 2004-08-16
    DATABASE RESOURCE MANAGER ( ORACLE 8I NEW FEATURE )
    ===================================================
    SCOPE
    8i~10g Standard Edition 에서는 Database Resource Manager 를 지원하지 않는다.
    Explanation
    Database Resource Manager란 OS에서 제공하는 자원 (예 : CPU 자원 )에 대해 DB
    차원에서 계획을 세워, 세부 관리를 할 수 있도록 해 주는 서비스이다.
    예를 들어 주간에 batch 작업을 처리하더라도, OLTP 업무에는 지장을 주지 않아야
    할 경우 batch 작업에 CPU 자원을 적게 할당해 주는 것이 바람직 하며, Resource
    Manager를 활용하여 CPU 자원을 batch 작업과 OLTP 업무에 서로 다르게 할당해 줄
    수 있다. ( Oracle 8.1.6 까지는 Resouurce Manager에서 CPU 자원에 대해서만
    관리만 가능하다 )
    1. 용어
    1) Resource Consumer Group
    사용자 session들의 집합. Resource에 대한 요구사항에 따라 나뉘어진 그룹.
    2) Resource Plan
         Consumer Group에 자원을 할당 해 주기 위한 resource plan directive들을
    포함.
    3) Resource Allocation Method
         Resource Manager에서 자원을 할당해 주는 방법/정책.
    4) Resource Plan Directive
         Resource Plan에 대해 자원을 할당해 주는 세부 내역.
    2. Resource Consumer Group
    * 기본 group
         [ 사용자가 삭제, 수정할 수 없는 group ]
         OTHER_GROUPS : active plan schema에 속하지 않는 consumer group의 모든
    session
         DEFAULT_CONSUMER_GROUP : consumer group을 지정하지 않은 모든
    session.(default)
         [ 기본적으로 제공되나 사용자가 삭제하거나 변경할 수 있는 group ]
         SYS_GROUP : SYSTEM_PLAN에 대한 high priority consumer group
    SYSTEM, SYS user에 할당한다.
         LOW_GROUP : SYSTEM_PLAN에 대한 low priority consumer group
    3. Resource Plan
         Consumer group에 속하는 session들은 해당 group에 대한 resource plan에
    따라 자원 할당이 결정되며, 자원 할당에 대한 세부 사항은 resource plan에
    대한 resource plan directive에서 지정된다.
         Resource plan은 subplan을 둘 수 있다.
    4. Resource Allocation Method
         Round-robin Method : Consumer group 내에서 session들에 대한 CPU 할당
         Emphasis Method : Consumer group에 할당되는 CPU
         Absolute Method : Parallel degree 한계 ( 예 : Parallel Query에서의
    degree )
    5. Resource Plan Directive
         Resource Plan Directive에 지정된 내용들은 resource plan에 따라
    consumer group에 자원을 할당할 때 반영된다.
    6. 구현 예제
         MYDB PLAN +-> MAILDB PLAN +-> POSTMAN GROUP (40% Level 1)
         | (30% Level 1) |
         | +-> USERS GROUP (80% Level 2)
         | |
         | +-> MAILMAINT GROUP (20% Level 2)
         | |
         | +-> OTHER GROUP (100% Level 3)
         |
         +-> BUGDB PLAN  +-> ONLINE GROUP (80% Level 1)
         (70% Level 1) |
         +-> BATCH GROUP (20% Level 1)
         |
         +-> BUGMAINT GROUP (100% Level 2)
         |
         +-> OTHER GROUP (100% Level 3)
         위 예에서 MYDB PLAN에는 2개의 subplan ( MAILDB PLAN, BUGDB PLAN )이
         있으며 각각 30%와 70%의 CPU 자원을 할당하였다.
         Level 1, Level 2, Level 3 는 우선순위 레벨을 의미하며, 하나의
         resource plan에서 동일한 level의 합이 100%를 넘지 못한다.
         ( Level 은 1부터 8까지 지정할 수 있으며 level 1이 가장 우선순위가
         높으며 level 8이 가장 우선순위가 낮다 )
         예를 들어 전체 CPU 자원의 70%를 할당 받은 BUGDB PLAN은 다시
         ONLINE GROUP과 BATCH GROUP을 두고 있는데, 이 둘의 Level이 모두 1이며
         두개의 percentage의 합이 100%이다. 하지만, 즉, level 1인 ONLINE GROUP
    에 90%를 할당하였다면, level 1인 BATCH GROUP에는 10% 이상을 할당할 수
    없다.

  • How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)

    How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)?
    The following is my configuration in the conf\mapViewerConfig.xml:
    <map_data_source name="mvdemo12"
    jdbc_host="127.0.0.1"
    jdbc_sid="orcl12c1"
    jdbc_port="1522"
    jdbc_user="mvdemo"
    jdbc_password="7OVl2rJ+hOYxG5T3vKJQb+hW4NPgy9EN"
    jdbc_mode="thin"
    number_of_mappers="3"
    allow_jdbc_theme_based_foi="true"
    editable="true"/>
    <!--  ****  -->
    But it does not work.
    After use "sqlplus mvdemo/[email protected]:1522/pdborcl", it connected to the Oracle database 12c.
    Does anyone know it?
    Thanks,

    For 11.1.1.7.1 use the syntax for jdbc_sid, i.e.
    //mypdb1.foo.com as described in the README,
    - MapViewer native (non-container) data sources can now use database service name in place of SID. To supply a db service name, you will use the same jdbc_sid attribute, but specify the service name with double slashes in front, such as follows:
      <map_data_source name="myds"
        jdbc_host="foo.com"
        jdbc_sid="//mypdb1.foo.com"
        jdbc_port="1522"
      />
    For 11.1.1.7.0 use a container_ds instead.
    i.e. instead of using
    <map_data_source name="my_12c_test"
                       jdbc_host="mydbinstance"
                       jdbc_sid="pdborcl12c"
                       jdbc_port="1522"
                       jdbc_user="mytestuser"
                       jdbc_password="m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q="
                       jdbc_mode="thin"
                       number_of_mappers="6"
                       allow_jdbc_theme_based_foi="false"
                       editable="false"
       />
    use
      <map_data_source name="my_12c_test"
                       container_ds="jdbc/db12c"
                       number_of_mappers="6"
                       allow_jdbc_theme_based_foi="false"
                       editable="false"
       />
    In my case the Glassfish 3.1.2.2 JDBC connection pool definition was
    Property
    url  jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name
    Uncheck the Wrap JDBC Objects option in Advanced panel, i.e. the Edit JDBC Connection Pool Advanced properties page.
    Add a JDBC resource for that newly created pool
    Use that in mapviewerconfig.xml as above

  • How to setup JNDI Name for Oracle Apps adapter?

    Hello,
    I am learning Oracle SOA 11g and trying to do some tutorial on Oracle Application Adapter.  I know how to configure JNDI for DBadapter and I did that successfully. I followed same steps to create New JNDI for Oracle Apps Adapter.
    1. I Created new data source using Path Services->Data Sources -> New Genric Data Source. Connection to database was successful and created new JNDI Name: jdbc/PKDTAPPS.
    2. Then Deployment-> OracleApps Adapter-> Configuration-> Outbound Connection Pools -> New and created JNDI Name eis/Apps/PKDTAPPS.
    However I did not find newly created JNDI Name in step 2 under Deployment-> OracleApps Adapter-> Configuration-> Outbound Connection Pools -> javax.resource.cci.ConnectionFactory.
    Please let me know if am I following correct steps to create new Oracle Apps Adapter JNDI Name or not.
    Since above approch did not work I created new JNDI for DBAdapter with same database connection details. And then latter on use that JNDI Name while creating Oracle Application Adapter in JDeveloper composite. And it allowed me to access Oracel Apps open interface. However while deploying the application it gave me following error.
    <Feb 16, 2015 10:50:59 AM CST> <Error> <oracle.integration.platform.blocks.deploy.servlet> <SOA-21537> <Sending back error message: There was an error deploying the composite on AdminServer: [JCABinding]
    [adapter-Apps-101-JournalImport.InsertJournal/1.0]Unable to complete unload due to: Cannot locate Java class oracle.tip.adapter.apps.AppsTableWriteInteractionSpec: Cannot locate Java class
    oracle.tip.adapter.apps.AppsTableWriteInteractionSpec..>
    Since I have no past experience kindly suggest me what is right way to do this.
    Thanks,
    Shri

    Hi shri,
    Can you check the targets of oracle apps adapter that is it deployed on both cluster and admin server both.
    Deployment-> OracleApps Adapter-> Targets
