the JRC, many cases can be on the same database server?

and if so, that that the advantage of this would be, because there would be no tolerance of breakdowns or of load balancing in question?

im just curious,

Thank you

I hope that this is just a rhetorical question. If we keep data and you want to start the instance on the same machine, the db_unique_name would do the trick, giving each one a different name. But in the cars, the instance name will change keeping the db_name even and also, the Vip would be alone for two instances. So no real advantage to do so would not be possible at all. No TAF or these things would be there because CARS is used for HA and when the only machine would come down, you would have lost everything. That said, I am always doubtful that you can even start multiple instances on the same computer even or not.

Just my 2 cents.

Aman...

  • Cannot open 2 Virtual Machines at the same time to access the same database

    People,

    Hello.
    I'm installing RAC Oracle Database 11 g 2 system with 2 Virtual Machines (rac1 and rac2) on top 3 VMPlayer.

    The VM rac1 and rac2 when one of them is stopped.
    Their locations are F:\VM_RAC\rac1 and F:\VM_RAC\rac2.


    I opened rac1 rac2 is running. But this error message appears:

    Error: "cannot open F:\VM_RAC\sharerac\asm1.vmdk drive or one instant records, that depends. Reason: cannot lock the file. »


    While rac1 running, I opened rac2. But this error message appears:

    Error: "cannot open F:\VM_RAC\sharerac\asm1.vmdk drive or one instant records, that depends. Reason: cannot lock the file. »


    2 error messages are the same. This means that I can not open 2and rac1 rac2 VMs at the same time. When we run RAC system, must open 2 "machines" or machines to more than 2 at the same time, so that all machines can access the same database server.

    My question is:

    Can all folk tell me how have rac1 and rac2 run at the same time?

    Thank you.

    Unfortunately no, Oracle RAC requires that all nodes can visit the same set of shared disks. If your database resides within the DSO, each instance ASM (one per node) must also see the same set of disks to ASM diskgroup containing the data of the database files.

  • Can I use the same NTP server configured in the firewall to guard

    I configured the NTP server in my VCSC Expressway it synchronized correctly, but I'm unable to configured in my VCSC Gatekeeper with the same NTP server address that is configured in VCScExpresway.

    Please suggest

    Hello!

    You use in.pool.ntp.org. This isn't a single ntp server, there is a pool of servers,

    then you might see different ntp servers, and they can also change and sometimes

    It can also happen that yo will get a limit down.

    If I get him here, I have for exmple get:

    $host in.pool.ntp.org

    in.pool.ntp.org has address 113.30.137.34

    in.pool.ntp.org has address 119.226.101.131

    and a little later, I got:

    $ host in.pool.ntp.org

    in.pool.ntp.org has address 123.108.225.6

    in.pool.ntp.org has address 125.62.193.121

    In any case you want to configure multiple NTP server addresses.

    So, if you want to use this area (India):

    * You must configure these three host names as described here: http://www.pool.ntp.org/zone/in

    * See who works for DNS resolution (which may also be the problem here)

    * you have a suitable internet access

    * see that the firewall is open to 123 to any host on the internet

    * If you are not in India use a different area

    On the VCS under Maintanance > tools > utilities you could for example check if you can resolve DNS and traceroute/ping external hosts on network.

    The other option is to find at least 2 NTP servers you know and that you can use and set up.

    then you could lock the specific IPS in the firewall, otherwise it should be open to all.

    Its also not hard to set up your own server NTP, incidentally.

  • Replication to a different diagram in the same database is a problem?

    Hello

    I'm about to start an integration project in which data needs to be replicated from a schema from A to B schema. These patterns are in the same database. We are looking for a non intrusive process to move data in real time throughout the day. At night, the data must be prepared for treatment. I think GoldenGate might be the right choice for this case. However, some people think it's weird using GoldenGate for replication within the same database, despite being in the other schema data. I do not wish to use ODI or other intrusive process.

    Is there a sort of recommendation in order to not to use GoldenGate in such situation (same database)?

    Hello

    Yes, it is possible and you can use Oracle GoldenGate for configuring replication between two schemas in the same databases. Only a GoldenGate environment is sufficient to achieve this goal.

  • The consecutive processes share the same database session?

    Assuming that we have two processes on the same page, which are performed one after the other. Can we depend on that they are running within the same database session?

    For example it is possible to define a database (sys_context) context in the first process, and refer to this context within a second (e.g. process DML).

    Or asking in other words: is the session DB from the pool of connections apex reused or returned to the connection pool after the first process?

    It's a little difficult to control, because only the negative case would be suffient to say it doesn't work that way. Just because the 10 tests on 10 worked will not guarantee that it is always the case.

    The same session of database is used for the duration of 'see the page' or 'accept the page' request. If a 'direct branch' (direction of the page without using the redirect) takes place after "accept page" the same session of treatment, is used to display the new page. See the use attributes initialization PL/SQL/cleaning of Code PL/SQL Code .

    However, several operations may be involved, as APEX will issue engages on different session state changes.

  • RMAN and repositories on the same database grid control

    What are the disadvantages of having the RMAN Repository and repository on the same database grid control?

    What effect does this have

    1. daily maintenance

    2. after disaster or high availability... or the recovery scenarios.

    3 is server performance with respect to the use of the CPU and memory - not desirable to have two repositories on the same database?

    Currently we have not a RMAN or a repository of GC. We intend to implement both. Angle of savings, it would be good if we can just build another data base for two repositories on an existing database server with 2 production databases. The server has enough CPU and RAM face for 1 new database, but that would mean an exaggeration to have 2 new databases.

    If it is not advisable to have two repositories on the same database, then we would need strictly two separate databases, in this case, we will need to go to a new database server host two databases, which the org seeks to avoid, as this would mean that to buy a new license.

    I tried searching a few books, but don't have no clear guidance on the same. Any opionion would really help. Thank you.

    Concerning

    S diallo

    Where this instance fails, all rman needs to restore is in the database control file. How to restore a database with rman from the command line, without a catalog. (The backup and Recovery Guide has details of how do.) This will get data back so that you can use the grid again control.

    In order to insure against a default of the machine hosting the instance, verify that the database is in log mode archive and protected with scheduled backups of hot and copy the backup files to another server.

    Other options for high availability, you have a license (Data Guard, RAC) could also be deployed for this instance, if you need more recovery options.

  • GoldenGate replication on the same physical server - REPLICATE always ABENDING

    Dear expert GG,

    I'm completely green with Golden Gate, so I would like to help on why my REPLICAT process abends right after that I put my source database object lines.  I'm following the writeup of Gavin Soorma -.

    Hello

    Since no one has replied, I can go with my assumptions that replicat process searches across data dictionary, and since he is a 11g Golden Gate executable, its not backward compatible with 10g.  To this end, I have duplicated my database with RMAN DUPLICATE ora11g, creating another database called ora11g2, changed my REPLOCAL. PRM file as follows (changes in bold):

    REPLICAT replocal
    SETENV (ORACLE_HOME = "/u01/app/oracle/product/11.2.0/dbhome_1")
    SETENV (ORACLE_SID = "ora11g2")

    I then rebooted the components again, and finally, I was able to replicate the changes to the GGS_OWNER table. GOLD ora11g, at the same table in ora11g2.

  • How have the Linux database server listener listen to the service in the Net of Windows XP Client Manager?

    People,

    Hello. I installed Oracle 11 GR 2 database server in the Oracle Linux 5 operating system.
    All customers (NetCA, DBCA, GROUND Deveoper, sqlplus...) works properly on the database server. The LISTENER_PT853 listener is listening on client tools under Linux successfully.


    I also installed Oracle database Client(SQL Developer, NetMgr, NetCA, sqlplus,...) in Windows XP. So that the client tools to connect to the database on Linux server, the listener in Linux must be tuned to the service in Windows XP.

    In Oracle Linux 5 Server Machine Net Manager:

    Service name: PT853
    Connection type: default database
    "TCP/IP Protocol".
    Host name: 192.168.196.102
    Port: 1521


    Listener: LISTENER_PT853
    Protocol: TCP/IP
    Host: 192.168.196.102
    Port: 1521


    I have test the Service PT853 with "SYS" username and password "SYS." The connection is successful.

    In the Windows XP Client computer, the information in the Net Manager is lower at:


    Service name: PT853_Linux
    Protocol: TCP/IP
    The host of the database Machine name: 192.168.196.102
    Port: 1521


    I test the connection by using "SYS" username and password "SYS" and got this error: ORA - 12514:TNS: listener does not currently of service requested in connect descriptor. There may be an error in the input fields or server may be ready to connect.


    Can I check the status of the listener in Linux Server machine as below:

    [user@localhost bin] $. / lsnrctl status LISTENER_PT853

    Its release: Service PT853 has 1 instance. PT853 of the Forum, State LOAN, has 1 handler for this service.


    Foregoing, we saw the listener in the Linux server machine only to listen to the PT853 service in Linux but not to listen to the service PT853_linux of the Windows XP client computer.

    Windows XP (192.168.196.101) and Linux (192.168.196.102) can ping each other successfully. So that client tools in Windows XP connection in Server database on Linux, the listener in Linux need to listen to on the service in Windows XP first.

    In Net Linux Manager, I add an address more (TCP/IP, 192.168.196.101, PORT 1521) to LISTENER_PT853, but gets the error.


    My question is:

    How have the Linux database server listener listen to the service in the Net of Windows XP Client Manager?


    Thanks in advance.

    Actually, no he didn't "need to create listner.ora.

    In fact, its problems stem from the fact that it * has * created one instead of letting some things by default.

    I give an example of my environment

    (CONNECT_DATA =

    (SERVER = DEDICATED)

    (SERVICE_NAME = orcl.test.al)

    )

    )

    ADR_BASE_LISTENER = / home/oracle/app/oracle

    [oracle@home admin] $

    Change host, name of service depending on your environment. Your port is 1521.

    Then, first run all the listener and database startup. If you do the opposite, with that you will need to register the service change the order of system registry.

  • Migration of the apex of one schema to another in the same database

    Hello

    I'm new to Apex and installed Apex 4.2 on a database and creates a dashboard based on some tables.
    Now I have to create a diagram in the same database and have to replicate all tables and should have the same dashboard.

    Now my question is-

    1 can I install Apex on the other schema and then having to export and import dashboards and reports to the installed Apex?
    2 is it possible that the installed Apex even can be used also for the other schema and can have two separate (Dev and Prod) environment?

    Help, please... Please provide any document or link for the same.

    Thanks in advance.

    Kind regards
    Sébastien Pallav

    A database can have a single schema of apex (APEX_040200).
    It is not a good idea for DEV and PROD in the same PB (so using the same data to the APEX). He makes hard development (because he may - or is - break PROD at one point).

    But - if you must - you can create two schemas: like A and B.
    Export your APP1 then import it under a different id (in the same workspace - but you can also set up two work spaces).
    Using the apex management console, change the schema by using your new imported application is to B. In this way, your app will run "as user B".

  • Is it possible to run vCenter Server and AUVS in the same database?

    Hello. My client has vCenter Server and VUM installed and running in the same database. Yes, the same database (not only same server database) and the same ODBC (ODBC VUM is 32-bit only).

    My question is whether it is supported or not and I would like a source VMware information, not only "it works fine for me".

    I can't find any definitive info on this VMware. Only something to wave in the installation and upgrade guides about or not to run in the same database ' ' (I guess they mean 'server') and it seems that the recommendation is to separate them for the 'large environments,' whatever that means.

    The environment vSphere 4.1 is currently, and there are about 20 guests and 150 virtual machines.

    If it is not supported, I guess the best way to go is to reinstall both from scratch?

    Thanks in advance!

    / Anders

    Yes, it is a supported configuration.  Since VUM and vCenter using different tables, you can share the same DB

    The database of the update manager that you use can be identical to the vCenter Server database. You can also use a
    separate database, or you can use existing database clusters. For best results in a large scale environment, you
    must use a dedicated Update Manager database that is located on one computer other than the
    the vCenter Server system database.

  • 12 c upgrade using the same database

    What is the process for the improvement of the 11.1.1.7 to the current version of 12 c? We will not do a full inplace upgrade. We have new hardware for the 12 c application layer, but will use the same database. Our database is multiple to and do not miss having to deal with all the data duplication and dealing with the deltas.


    Is it possible to install 12 c on the new hardware, and then point the current patterns of these two instances? The upgrade of the patterns would be the only thing that needs to be done to allow the new instance to work with the new application?

  • ORA-17629: unable to connect to the remote database server

    Hello

    I have put Dataguard in place with primary and 1 physical standby for learning/test database:

    I do NOT plan the unloading of RMAN backups on the physics of the day before.

    Recorded the primary database with RMAN and when "resync catalog db_unique_name all;" is issued.
    I get the following error:
    ---------------------------------------------------------------------------------------------------------------------

    When I tested missing missing datafile and control file scenario on the primary database, it worked (Advisor to recover data)

    However, missing datafile scenario does not work on the physics of the day before.
    Here are the steps I followed:
    ********************************************
    1 renamed a file of physical data - in standby mode:

    bash - $3.2 ls - ltr

    Total 107832

    -rw - r - 1 oracle oinstall 52429312 16 September 12:19 asttest_redo03.log

    -rw - r - 1 oracle oinstall 61874176 Sep 29 15:41 asttest_temp01.dbf

    -rw - r - 1 oracle oinstall 52436992 5 Oct 11:00 rmandg_data01.dbf

    bash - $3.2 mv rmandg_data01.dbf rmandg_data01.dbf_old

    bash - $3.2 ls - ltr

    Total 107832

    -rw - r - 1 oracle oinstall 52429312 16 September 12:19 asttest_redo03.log

    -rw - r - 1 oracle oinstall 61874176 Sep 29 15:41 asttest_temp01.dbf

    -rw - r - 1 oracle oinstall 52436992 5 Oct 11:00 rmandg_data01.dbf_old


    2. restore the datafile (find the data file # view v$ recover_file):
    RMAN > restore datafile 5;



    From restoration to 5 October 11

    Segmentation fault


    3. in spite of the error, published "recover datafile command.

    4 RMAN > recover datafile 5;



    From pick up to 5 October 11

    allocated channel: ORA_DISK_1

    channel ORA_DISK_1: SID = 10 type of device = DISK

    5. manually copy the physical primary datafile - in standby mode, & then problem recover RMAN command:
    bash - $3.2 scp oracle@msudrainier:/ora03/oradata/asttest/rmandg_data01.dbf.

    RMAN > recover datafile 5;

    RMAN-06067: RECOVER the DATABASE required with a backup control file or created


    6. of course RMAN commands have failed to restore the missing data file;
    So I renamed the file to original and rebooted repeat services applies - this restore the data file and now the configuration state of the DG is normal.
    *********************************************************************************

    Not quite sure if I'm still he hands the right way or if the error above is related to RMAN not able to synchronize with the physics of the day before.

    The documentation I want to talk to is here (1 paragraph):

    [http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/rman.htm#BAJDFBDD | http://download.oracle.com/docs/cd/B28359_01/server.111/b28294/rman.htm#BAJDFBDD]


    Any pointers/direction and advise is greatly appreciated.

    Best regards

    If the necessary connection string a target/sys and a catalogue

    RMAN target sys / catalog /@rcatalog

    I did my standby

    Will try the primary

  • Can I use an ACS as RADIUS and GANYMEDE to the same ASA Server?

    I want to GANYMEDE to make the accounting of the SAA, meanwhile, the ASA need RADIUS for authentication ssl vpn. Is it possible to reach this object with only a CSA?

    Yes, you can use both. Allows you to add ASA as radius and Ganymede.

    ACS-->---> aaa-client network configuration

    (1) ASA---> 1.1.1.1---> authentic using Ganymede

    (2) ASA1---> 1.1.1.1---> optout by radius

    Don't forget the host name cannot be the same.

    Kind regards
