RAC with multiple databases

hi,
we are evaluating a design for the configuration of 3 databases in 10g RAC in linux
Available HW: 2 servers each with 32 gb ram
No of databases need to be configured :3
what would be the effective configuration?
the options we think are,
1) One 2 Node RAC with 3 databases or
2) Three 2 Node RAC each with 1 database each
what would be the licencing cost in different options
please help
tia,
newbie

hi,
sorry, am new to RAC.
heard about one implementation wherein with a h/w of 2 servers,
1) 2 node cluster for one database
2) single node cluster for the second database in one of the servers.
is it possible to configure multiple clusters on the same machines?
here in our case, we have 3 databases that need to part of RAC configuration.A single node cluster? A "cluster" implies two or more servers.
If you have two servers, you can create two node cluster for any number of RAC database(s).
Also you can create stand-alone database(s) on either server.
If you use VM, you can cluster as many VM machines as you have configured.

    how to investigate high io in a RAC with multiple databases?

    RAC is saying that a single server lacks the processing capacity needed for databaseA. So additional databaseA instances on additional servers are needed in  order to meet the processing demands for databaseA. Thus RAC is required.
    Multiple databases on a single server says that the server has spare processing capacity and that it can not only deal with databaseA processing demands, but also with the processing load of databaseB.
    So how does your statement about running multiple database RAC instances on the same RAC server node, make sense? And does your I/O issue not immediately point to the fact that no, RAC server1 cannot deal with the I/O resources required by both databaseA and databaseB?
    After all, how is I/O scaled on RAC? How is ANYTHING scaled on RAC? By adding more databases to a RAC server node? Of course NOT!!
    RAC scales by adding more servers (with a new database instance each) to a physical database in order to scale processing capacity and I/O. By adding more I/O channels to access the SAN/shared storage. By adding more CPUs to increase processing capacity.
    Bluntly put - multiple RAC database instances on a single RAC server node is kind of an idiotic approach to scalability in my view....

  • Can we link one application instance with multiple databases ?

    We have R12.1.1 and db is 11.1.0.7 on redhat 5.3 ( 64 bit).
    Can we link one application instance ( apps / , inst / ) with multiple database ( db / ),
    is this possible ?
    if yes how ?

    No. You cant link application tier with more than one database.

  • RAC with Multiple controlfile's

    Is it possible to start multiple oracle instances with different controlfiles (with one database name/alias) instead of using the common controlfile.
    right now we are using all files in common except pfile like standalone pfile for each instance.
    The way we are able to control the database with pfile/like block size and some other common parameters.
    in the same way does the oracle 10g or any future database support the separate controlfile for each instance.
    DBA should be able to choose the controlfile parameters/datafiles .

    I have 7 application systems that need 7 different Oracle database servers. It is not that simple. There is no such "+rule of thumb+" even that states that one should have one application system per database. So you're assumption that because you have 7 app systems you need 7 Oracle db servers, is very much flawed.
    There are numerous factors that dictate how resource intensive that app system is and the size of the server it needs (or the number of servers in terms of RAC).
    How many nodes are to be configured to support 7 instances of database?7 what instances? 7 dedicated non-RAC instances? It is seldom technically sound to run 7 (or more) database instances on a single server platform. Often better performance and scalability are achieved by consolidating those difference instances into a single instance.
    7 RAC instances? A RAC instance per server is needed. Thus 7 servers would be required.
    But this is IMO still very much irrelevant thumb suck equating 7 apps to need 7 RAC instances.
    This is not how client-server architecture works. It is not a hardware architecture - it is a software architecture. For that reason it is wrong to assume that each s/w layer or component in the client-server architecture needs a separate and dedicated h/w platform.
    Client-server does not scale using hardware alone. In fact, scalability via h/w alone can be a dead-end street running into a massive and unmovable wall.

  • Working with multiple databases

    Suppose I have a large project that follows the formal "SDLC" model for software development; it has various stages, environments, development, integration testing, system testing, UAT, etc. Each of these environments is on its own dedicated Oracle database.
    An query-only Apex application is built as a testing aid for the various environments to quickly see reports, test data conditions, etc. This application is deployed to all the environments.
    With other web development technologies (PHP, ASP/.NET, etc) which live outside Oracle and access Oracle using a userid/connect string. If some aspect of the application needs to be changed, it is done in 1 place (the application) and the new/modified functionality is available for use against all the enviroments (just change the connect string in the URL or some config file to access different environments).
    With Apex, the change to the application has to be done in all the 4 environments. This seems like a case where the Apex architecture (all app metadata in Oracle) is a disadvantage.
    Comments? Thanks

    That would be that case if you are only talking about only moving through the SDLC with your database changes yes? In many cases, you make changes both to the underlying database structure/code and the application (PHP, ASP, etc) so your application would "follow" your database code wouldn't it?

  • DR type restore of 10gR1 RAC with ASM database to another cluster

    Hi,
    We have a requirement to restore the image copy of our production database to another location. The production database is a 10-node 10gR1 RAC deployment with ASM. The image copy is in the FRA.
    We want to restore this image copy onto a 2-node 10gR1 RAC cluster, which is also running a development environment. We have so far used the 'backup copy copy of database' command to pipe the image copy from the FRA to an NFS mounted filesystem. We plan to restore (and convert the names) the files from here. I have a list of steps we need to undertake - like adding the production database metadata on the development cluster into CRS, restore the spfile and controlfile, restore and convert the datafiles from the production ASM diskgroup to the development ASM diskgroup.
    has anyone out there done this? Are there any nasty 'gotchas' or pitfalls?
    Please, tell me your pain so I can spare it myself :o)
    regards

    We are planning to take cold backup through RMAN. But now the issue is that if something going wrong with the storage then both the diskgroup on the same storage will not be mounted.
    What should be the backup & recovery strategy for this scenario? How to bring the server back online?The strategy depends entirely on the risk analysis and assessment. Do you need to be able to recover the database to the moment just before it crashed? Do you need point-in-time recovery? What are the availability requirements? Etc.
    Databases can be quite diverse in nature. It can be fairly static with very few changes, to very dynamic to totally dynamic. In some cases, the database only needs to be restored as a "container" (structures with no data) as that is all the processes need and as these will supply the data. In other cases, the entire database with all committed transactions to the second before the crash is needed. In a few cases, you may want to use Data Guard and standby/clone databases instead.
    There is no single set of rman instructions that you can copy-and-paste to implement any of these diverse backup and recovery strategies. You need to determine and define your backup, restore and availability requirement first - before looking at which rman commands to use and in what sequence, where and when.

  • Channel Bonding? Oracle RAC with multiple redundant network

    We are planning on setting up on Oracle RAC 10g on Linux.
    We have redundant switches, so I would like to set up the network to have some version of network redundancy.
    Under windows, it is called 'teaming'. Linux is 'channel-bonding'
    I just want to make sure if I setup the channel-bonded interfaces, it will be supported with RAC. Has anyone done this before??

  • Same sql query with multiple database links

    Hi All,
    i want to execute an sql query for a SELECT LIST Item. which should use database links in it's query.
    i'm having a list of database links in the region. say :LOC which is having 10 items each linking to different databases.
    i want to use following query for another item in same page.
    select customer_name from working_lines@:LOC where
    phone_no:phone_no
    can i do this.
    Thank you All.

    What we have done before is to create a report based on a PL/SQL procedure that returns a SQL statement.
    The PL/SQL code grabs the "selected" database link from :LOC and parses the SQL QUERY you want to execute replacing some token (like [LINK]) with '@DBNAME'.
    Lets say your SQL statement is coded like this:
    mySQL := 'SELECT cust_name FROM working_lines[LINK] where phone_no = :Phone;'
    Then all you would have to do to replace '[LINK]' with the proper DB alias would be:
    mySQL := REPLACE(mySQL, '[LINK]', '@'||:LOC);
    and then return the new SQL ...
    if :LOC has something like 'V10GPROD' your SQL would look like :
    SELECT cust_name FROM working_lines@V10GPROD where phone_no = :Phone;
    The beauty of this is that you can also include a "null" option that means the select statement will be executed on THIS database...

  • Possible to sync multiple phones with multiple database?

    Forgive me if this has been covered, if so please point me to the right thread...
    Ok, I have two phones and one pda. I'd like to keep different database (and yet be able to selective choose data from one database to another). Is this possible?
    The reason for this setup is that I have one USA phone and one Taiwan phone and one PDA (with less dialed contacts). Obiviously, when I'm in Taiwan, I don't need any USA contacts in my Taiwan phones. (I know phones nowadays have enough memory to fit 100s of contacts, but I don't wan to scroll through a bunch of contacts that I don't need.)
    Any solution to this using iSync?
    Thanks!

    It depends entirely upon your mobile handset. Generally speaking, you can choose to synchronize by Address Book group, and not synchronize your entire Address Book database with each device. This is certainly supported by iSync for Palm devices.
    To determine the options for each handset and your PDA, select each one in iSync to drop down a configuration dialog specific to that device.

  • RMAN with multiple databases

    Hi,
    I need to define a mechanism with RMAN to backuptwo databases where information is copied from one to another by using Oracle Data Integrator CDC.
    How can I backup and recover both databases and it still sync?
    Thanks
    Homero

    Yes.
    And that is why I said "If you create distributed transactions between two Oracle databases, a Global SCN is synchronised".
    YOU CREATE distributed transactions.
    Test it out.
    Put two dummy tables in each database.
    Have a database link configured.
    Run some distributed transactions.

  • 3.1 upgrade with multiple databases

    We have 3 Oracle databases (10g) with APEX on a server. Two databases run with APEX 3.0 & one still runs with APEX 2.
    I want to upgrade to APEX 3.1. I ran the apexins script against the APEX 2 database, but now I'm faced with the step of copying the new 3.1 images over the old image file. My questions is what will happen to my existing 3.0 APEX installations if I copy the new image files?

    Hello,
    >> For some reason, I was able to run both APEX 2 & APEX 3 on the same server,…
    By “on the same server” you probably mean the same HTTP server. This is a supported configuration. A single OHS can support more than one APEX instance, and they don’t have to be the same version. A single database can’t support more than one version of APEX.
    >> … but I can't figure out why except to say that the 2.0 and 3.0 images were somehow compatiable …
    New ‘images’ directory, for a newer version, usually add features – icons, themes, templates etc. – to the directory, and don’t delete old stuff. Even the built-in JavaScript library maintains backward compatibility. That means that early version of APEX, like 2.x, can find anything it needs in an ‘images’ directory from 3.x version.

    I’m not sure what you mean by compatible, but the 3.1 version of ‘images’ is quite different – content and structure wise - from the 3.1 version. Still, application that was built using 3.0 should run with the 3.1 ‘images’ version. The reverse direction is, of course, not possible.

    nother pool: MultiTransactionTestHi. You can't domultiple DBMSes in one transaction unless you use an XA driver and
    an XA transaction. Your workarounds are:
    1 - Use an XA driver, datasource, and tx
    2 - If you're just reading, you can use non-transactional datasources. Do make sure you
    always close your connections...

  • ASM with multiple databases

    I need to create lots of databases on a single server for development/testing work but am not sure if I should create a single ASM instance to serve all of them, or one ASM instance per database. I need all databases to use different disk groups anyway, so is there a "best" way?
    Would this change if the databases are for production use?

    >>>>I should create a single ASM instance to serve all of them, or one ASM instance per database.
    You can have only one ASM instance per server..
    I need all databases to use different disk groups anyway, so is there a "best" way?
    You can create one ASM instance and then create different Diskgroups and have each instance use a different diskgroup.
