Two database with the same sid but different ORACLE_HOME on one host

two database with the same sid but different
ORACLE_HOME on one host,and if configure them with
two differnt lisnter staticaclly,this abosultely work
because in the lisnter.ora we must provice
ORACLE_HOME variable,with this ORACLE_HOME the client
can differentiate which database to connect,but if
use dynamically register feature,how can the client
tell which database to connect?

Also note that this type of configurtion may not be supported.
Just because a given configuration works in certain given conditions does not mean that it would be supported.

  • Why can't iTunes down load two songs with the same name but different artists to my iPhone?

    I noticed this a couple of years ago but had forgotten about it. Today I purchased two songs, both called Bop Gun (One Nation) but by different artists. When I looked at the purchased list on one appears. If I go back to iTunes and download the other one, the former disappears. Are they honestly saying that these phones are intelligent enough to distinguish a song by artist rather than track listing?
    Epic Fail!!!

    Usually a song is uniquely identified by song name, artist, album and track number. That said internally I suspect the iTunes Store may allow one song to appear on more than one album while they only need to store one copy of the audio data. (They must also be able to cope with the situation, for example, where the UK & US version of an album have a different track order). It is also possible there is an error in the database that means you're not getting the song you're expecting. If you can't successfully download the two (presumably) different versions of the song then use the report a problem links in your account history and explain the issue. Hopefully the iTunes Store support staff can get it resolved.

  • Merge Two Tables with the same columns but different data

    I have a table that has the following columns:
    Current Table Definition
    commonname
    family
    genus
    species
    subspecies
    code
    I have a number of entries that don’t fit the current table definition – that is that they only have a common name or description and a code. These records don’t actually represent a species but are needed for data entry because they represent an object that may be encountered in the study (Bare Ground – which isn’t a species but would need to be recorded if encountered). So I would really like 2 tables:
    Table 1 Miscellaneous
    name
    code
    Table 2 Plant Species
    commonname
    family
    genus
    species
    subspecies
    code
    I would like two tables so I can enforce certain constraints on my species table like requiring that the family, genus, species, subspecies combination is unique. I can’t do this if I have all the “other” records that don’t have a family, genus, species, or subspecies unless I put in a lot of dummy data into the fields to make each record unique. I don’t really want to do this because these miscellaneous records really don’t represent a specific species.
    So – the problem is that while I want this data separate I will need to point a column from another table to the code column in both tables.
    How is this best done? Table? View? Merge?

    Hi,
    Actually you don't have to use scope refs. Sorry but I misunderstood you earlier. Here is a complete example that does exactly what you want. Notice how I added the constraint to the materialized view. Also notice when we try to insert a code in tbl3 that doesn't exist in the view, we get an error. HTH.

  • PFCG, two roles with the same object but different values

    Hi, Can you help me?
    I need to know if it's possible have two roles like this:
    role A - Object werks = L001 and LIKP-LFART = LF
    role B - Object werks = L005 and LIKP-LFART = ZLF
    If the some user have role A and role B it's possible that he doesn't have authorization for werks = L005 and LIKP-LFART LF?
    Thanks
    Dora

    I guess you made fat figure on the words: "it's possible that he doesn't have authorization for werks = L005 and LIKP-LFART ZLF", right?
    If so, it is impossible.
    When SAP doing the authorization check, it call the function "authority_check", input the Object, the filed and the value to check.
    if some one have role A and B, SAP will check authority both in Role A and Role B.
    What you need to do should be separating the Object into a subrole and assign it separately.

  • Is it possible to have 2 trans with the same tcode but different langs

    Dear forum members,
    I would like to know if it is possible to have in the TSTCT table u2013 two entries with the same TCODE value but different SPRAS value (the language field)
    Thanks for your help,
    Roy

    Hi Roy,
    It is possible. Just go to TSTCT table and check for the entries. On the selection screen give some Tcode (say OKEU) and execute. You can see different languages in which it is maintained.

  • Two AM's with the same name but different forms causes Deployment problems

    Two Masters forms, DOC & PM are cloned except for the "where clause" in the View's query and the titles in their JSP's.
    DOC workspace has a BC project and a BC4JSP Project. The BC project comprises of the EO and VO named ComVsStaticValue. In the Edit prop-> query for the VO I have specified the "where clause" as VSSV_VS_CODE='DOCTOR'.
    In Java Webserver :-
    The JSP's are located in C:\source\Doctor\ .. and the *.xml and *.class files generated by the BC proj is in C:\source\Doctor\pol_ValueSet\..
    If I execute Doctor in JWS the records are getting filtered properly.
    PM workspace has a BC project and a BC4JSP Project. Again The BC project comprises of the EO and VO named ComVsStaticValue. In the Edit prop-> query for the VO I have specified the "where clause" as VSSV_VS_CODE='PAY_MODE'.
    In Java Webserver :-
    The JSP's are located in C:\source\PMode\ .. and the *.xml and *.class files generated by the BC proj is in C:\source\PMode\pol_ValueSet\..
    If I execute PM in JWS, the PM's JSP comes (the title is correct) but the records pertaining to DOC appears. I checked the View's xml file in C:\source\PMode\pol_ValueSet\ the "where clause" is correct. The xml & classes have the same name but their contents are different.
    I want to know whether this problem is because both have the same name for the AM and the BC4JSP's property file.
    Please clarify.

    Deploying two app modules with the same name will definitely cause problems.
    The JSPs use the information in the properties file to connect to the application module and get the data they need from the appropriate View Objects in those app modules. If you have two app modules with the same name, when a JSP tries to connect, it has no way of knowing which one of the app modules to connect to if they both have the same name.
    You could:
    1. Just use one application module that contains all the View Objects you need to access.
    or
    2. Rename one of the application modules or the package it is located in so the names are distinct. If you choose this method, you will also need to update the JSPs (specifically the 'registerApplicationFrompPopertyFile' method call), and your JSP project's appmodule property file.

  • Is it possible to have 2 instances with the same name but different edition in the same server?

    Hi everybody!
    I have in a little trouble ....
    *** Scenario.
    Oracle Enterprise Edition 11gr2 over Oracle Solaris 11
    3 instances: PROD, QA, DEV
    1 ASM instance
    Listener ports: 1520, 1530 & 1540
               Those are production system
    *** The problem:
    Customer can't pay Oracle EE, they want to change to Oracle Std One
    Limitations:
    I cant have a similar system to test.
    *** My idea:
    Install Oracle Std One, in the same path:
    /u01/app/oracle/product/11.2.0/db          <-- EE
    /u01/app/oracle/product/11.2.0/db_one   <-- Std Ed One
    ASM:
    /u01/app/11.2.0/grid          <-- EE                    +ASM
    /u01/app/11.2.0/grid_one   <-- Std Ed One        +ASM1
    Create databases:
    Asign similar disks to +ASM1
    Create DGs on +ASM1
    Create databases: PROD, QA, DEV for Std Ed one
    - is it posible that they have same instance name?
    - if not, i suppose create as: PROD1, QA1, DEV1
    Configure Listener port : 1521, 1531 & 1541
    Migration technique:
    Create Tablespaces, schemas
    Lock users in EE
    down listener: 1520, 1530 & 1540
    Import data of final users in a window maintanance
    configure and up listener: 1521, 1531 & 1541
    Customer should test access and apps in new
    Please tell me if my Idea is reallistic, all comments are going to be very apreciated.

    sol.beach
    I suppose end customer use a port per database in order to separate in a logical way the access to the databases,
    i mean PROD, QA & DEV has the same users.
    Hemant K Chitale
    1. I've seen physical servers with 3 ASM instances: +ASM1, +ASM2, +ASM3
       on Solaris & Oracle 10g, I suppose is posible on 11g
    2. The sever has occupied 2  sockets (2 physical CPU), so I can use Oracle Standard Ed One.

    Thanks for your comments.

    1. - You cannot run two ASM instance simultaneously on one Server, but you can run many Oracle database simultaneously
          on the same server which they use the ASM as storage type.
      As a mentioned to  Hemant K Chitale, I've seen a system with several instances running
      About
         "you can run many Oracle database simultaneously on the same server which they use the ASM as storage type."
      I'm not sure if i can use the same ASM which is part of a current Enterprise Ed over the new installation with Oracle Std Ed One.
    2. - Why you want the same instance name?
    If it is about the service name, which has by default the same instance name, just you can create a different instance name
    and create the service name with the name that you wish.
    SQL> alter system set service_names='instance_name';
    Is a similar name, not the same
    PROD, QA & DEV
    PROD1, QA1 & DEV1
    I consider add "1" at the end to refer "Oracle Standar Ed One"
    But I agree with you, i can customize throught service_name.

  • How do i back up 2 different devices with the same ID but different content, without losing any content?

    I have 2 iPads but just one ID. I use the iPad 2 and my daughter uses the mini. Both have different contents, as her mini contains a lot of videos that she's taken. Niw, I just bought an iPad Air and want to essentially transfer my iPad 2 contents there and also transfer my daughter's mini contents to that iPad 2. If I back up both to the same computer, will I have access to both sets of content and transfer the data to whichever device as I see fit? I just want to make sure so I don't lose any of her content (especially).
    Thanks!

    Using iTunes on a computer, be sure to set the backup(s) to be stored locally and not the iCloud for efficiency's sake. If all devices belong to the same AppleID, each one will store its backup on a separate file, and if appropriate, you can choose any for a restore as needed. As shown in Diavonex pic, the backups are listed in Preferences / Devices. Hover the cursor over each and a popup will appear detailing which device it belongs to. And you can keep, if needed, more than one backup of a device: control-click on the backup to preserve and choose Archive from the menu (Older backups get overwritten otherwise).

  • I have two libraries on the same computer but different logins, there is my user account for the computer and then there is my grandma's, how do i get my music without having to resync on both libraries?

    this computer has two logins, my grandma's (which is the administrator) and mine, itunes is on both logins but on my login i have some music there and hers i have my other music.. i want to be able to redownload my music on my ipod touch with out having to resync back and forth between libraries.. how do i combine the libraries because if i go with one or the other i lose my music i have purchased, on both libaries the music belongs to me not my grandma,
    Also, a few weeks ago, I loaned the IPOD to somebody and they told me that evidently the IPOD had been hacked and that it had lost all the music.  When I got it back, I re-synced it and got some of the music back.  After talking to other people, I now suspect that my "friend" tried to do something he wasn't suppose to to and the IPOD shut down or that he was trying to create an Apple ID of his own without paying for it.  Now that I have it back, I just want to get the music back that I paid for that is already associated with my ID and that is in my two libraries.  I can see them in there (on the computer), I just can't access them to download  them on the IPOD.  Can you help?

    There are actually a few methods for using more than one iPod on a single computer: How To Use Multiple iPods with One Computer
    Just to summarise what's in the link above:
    Method one is to have two Mac or Windows user accounts which by definition would give you two completely separate libraries.
    Method two is to set your preferences so that either one or both iPods get updated with only certain playlists within one library. If you've had no success with this you can have a look through the guide on this page: Loading songs onto iPod automatically
    Another option when using a single library is to set one or both of the iPods to manual update: Managing content manually on iPod
    You can read about Windows user accounts here: Using Windows XP User Accounts

  • Is it possible to install two SAP system with same SID but different instance numbers on one host?

    Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?

    If no, then why?
    Thanks in advance.

    Is it possible to install two SAP system with same system ID (SID) but different instance numbers on one host?
    Yes, it is possible. If one is CI (PAS) and the second one is an AS (AAS). In this case there will be only one database.
    If you are talking about two separate SAP systems with separate databases (Eg: A BI and an ECC) with the same SID then the problem will be with the database (Eg: Oracle)
    The database will be installed under /oracle/SID/112_64 (ORACLE_HOME) unless one database is running on 10 G and in that case the ORACLE_HOME will be /oracle/SID/102_64
    The next issue will be with the SAP file systems like /sapmnt/SID
    The most important problem will be with the switch to the sidadm and orasid users and the conflicts there. If there is a need to stop one of the SAP systems and if you do a switch to sidadm and issue a stopsap command which system will be stopped ?
    These are few of the many problems I can think of.
    So if we are talking about two separate systems with their own databases I would rule out the possibility of having two systems with the same SID.

  • Two databases in the same host.

    Hi Group,
    I have a doupt, It's possible that two databases with the same name, live in the same host, if they have different OracleHomes, and the SO users who were installed with are different? eg.
    SO user: oraqas
    OracleHome1 : /qas/u01/app/oracle/product/9.2.0
    BD: prdsia01
    SO user: oracle
    OracleHome2: /u01/app/oracle/product/9.2.0
    BD: prdsia01
    If not, what do you recommend?
    Thanks a lot

    It's possible that two databases with the same name, live in the same host,
    if they have different OracleHomes, and the SO users who were installed with are different? what is "SO users"?
    what is "BD: prdsia01"
    Yes, two Oracle databases with same ORACLE_SID can reside on same system as same time.
    The only restriction is that only one instance can be online at a time.
