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 yes, then how?
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.

SID Problem : could not register two ABAP systems with same SID

Dear Expert:
We have to register two ABAP systems on different host to SLD, and these two systems have same SID.
We use rz70 to do this, but we found the lastest registration will overwrite the previous registration,
that
means we could register them both in the same SLD. (we checked this in Technical system area).
How could we do this? It makes us crazy........
Thanks very much
Ray

Dear Stefan,
Thanks so much for your anwser.
But the dilemma is in one SLD we achieved this, but it is only for one case and we could
not apply this for other systems.
This is the snapshot in our SLD for techical system:
Name                                        Host                             Version                                     Last Update
D01   on eisdq01                     eisdq01                         700                                           2010/12/06 12:45
D01   on eisdv01                     eisdv01                         640                                           2010/12/06 11:40
We don't know if this is the illusion that SLD could do this? But for other systems, e.g two Q systems
the lastest registration will overwrite the previsou one.
Thanks very much.
Welcome suggestions from very guru.

Create a Connection on TREX for 2 systems with same SID

Hello world,
Here is my case,
We have a PRO systems With SID=PRO On Host= production , and a Sandbox system with also SID=PRO On Host=SANDBOX
now i need to create a connection in TREX in parallel so when i add the 2nd one it just edits the 1st one that i have already made
So is it possible to create 2 connection of same SID but diffrent Hosts In parallel?
If Yes how ?
Thanks In Advance...
Ahmed Salam

Hi Ahmed,
it could be possible from the TREX perspective , however such configuration isn't supported . The reason for this is that the SAP applications create indexes using the ABAP system ID and client as a part of the index names (f.e. esh:e10002~e10002~acc_sid~sid). As it's not possible to create an index with the same name 2nd time, you will not be able to use the TREX instance with two systems with same SID.
Best regards,
Mikhail

Two methods with same name but different return type?

Can I have two methods with same name but different return type in Java? I used to do this in C++ (method overloading or function overloading)
Here is my code:
import java.io.*;
public class Test{
public static void main(String ar[]){
try{
//I give an invalid file name to throw IO error.
File file = new File("c:/invalid file name becasue of spaces");
FileWriter writer = new FileWriter(file ,true);
writer.write("Test");
writer.close();
} catch (IOException IOe){
     System.out.println("Failure");
//call first method - displays stack trace on screen
     showerr(NPe);
//call second method - returns stack trace as string
        String msg = showerr(NPe);
        System.out.println(msg);
} // end of main
public static void showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     String stackTrace = sw.toString();
     System.out.println("Null Ptr\n" + stackTrace );
}//end of first showerr
public static String showerr(Exception e){
     StringWriter sw = new StringWriter();
     PrintWriter pw = new PrintWriter(sw);
     e.printStackTrace(pw);
     try{
     pw.close();
     sw.close();
     catch (IOException IOe){
     IOe.printStackTrace();
     return sw.toString();
}//end of second showerr
} // end of class
[\code]

Overloading is when you have multiple methods that have the same name and the same return type but take different parameters. See example
public class Overloader {
     public String buildError(Exception e){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( e.getClass().getName() )
               .append( " : " )
               .append( e.getMessage() ) ;
          return buffer.toString() ;
     public String buildError(String msg){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( msg ) ;
          return buffer.toString() ;
     public String buildErrors(int errCount){
          java.util.Date now = new java.util.Date() ;
          java.text.DateFormat format = java.text.DateFormat.getInstance() ;
          StringBuffer buffer = new StringBuffer() ;
          buffer.append(format.format(now))
               .append( " : " )
               .append( "There have been " )
               .append( errCount )
               .append( " errors encountered.") ;
          return buffer.toString() ;
}Make sense ???

Adding systems with same SID in SMSY - solution manager

Dear All,
We are having systems with same SID's which belongs to different landscape created for various customers.
Currently We are having only one solution manager.
I consider this example for explanation.
Customer 1 : DEV --> QAS --> PRD ( SID's)
customer 2 : DEV --> ACC --> PRD ( SID's)
I would like to add these 6 systems in a solution manager. For Customer 1 , I have included the systems in SMSY . But when i tries to add DEV, PRD for customer 2 , it fails since this SID's are already present.
Is there any other way to include by giving the different SID's DE2 but with correct IP and host Or we need to have one more solution manager ? Please anyone suggest me on this
Thanks
Raj

Dear Juan ,
We can add systems with same SID in smsy. I have attached the way in which i have done. This may help others. Thank you all for your suggestion
Only use more than three characters if your landscape contains multiple systems with the same system ID (if you have a mirrored backup system that has the same ID as the original system, for example).
If multiple systems in your landscape have the same system ID, choose as system name the system ID with a suffix of up to 5 characters (a sequential number, for example) to create a unique system name.
The system accepts a system name of more than 3 characters if you choose Enter to confirm.
Thanks
Raj

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.
If this setup is for a configuration that has any value, please also Contact Oracle Support to get their inputs on what you are trying to accomplish.

RFC connection between two SAP systems (with SAP router)

Hi!
I would like to set up a RFC-connection from SAP Solution Manager to other SAP system.
The network connection between the servers is VPN.
How can I set up this RFC-connection, if my connection between two SAP systems looks as follows,
(I use the following SAP routers)?
my server --> customer
my server --> internal SAP Router server xy (10.101....) --> SAP Router customer 2 (10.1....) --> SAP System customer (134....)
Back-way
SAP Systeme customer --> SAP Router customer (134.1....) --> internal SAP router (212.6....) --> my server
How can I set up this RFC-connection, if my connection between two SAP systems looks as follows,
(I use the following SAP routers)?
something like:
/H/10.101..../S/sapdp99/H/10.1.4..../S/sapdp99/H/134...
Thank you very much!

Is it possible to install two GUI version on same server??

Hi all,
I am facing a typical problem.
I am using ECC 6.0 on Solaris server and accessing through CITRIX where SAP GUI 6.4 is installed.
I have got Internet Explorer 7.
Some dumps are cumming like message_server_x
Then I went for SAP GUI 7.1 in which error is not cumming.
There is only one CITRIX server at this moment and users from all the location is using through this on live system.They are not getting such issue.
But we the new project team is getting this issue of dump.
Now the question is whether it is possible to install SAP GUI 7.1 seperately on the same CITRIX server where SAP GUI 6.4 is running???
Thanks in Advance
Souren

I do not have knowledge in the field of CITRIX metaframe, i'm only can advise you read about the
"Application Isolation Environment" (AIE) --> For example read in http://support.citrix.com/article/CTX109664
. May be it's help you. The best way update your 640 version. Regards.

DB Copy (MSSQL) between two SAP systems with different level and Components

Hi,
we have a SAP system release mysap 2004 SR1 and for "the upgrade project to SAP ECC 6.0 " we installed a new mysap 2004 in a new hardware (sap03) where we have also solution manager running. The new installed Mysap 2004 SR1 is alos running fine in the new hardware.
Now we would like to do DB copy from the old system (sap02) to the the new system sap03 and then we will do the upgrade to SAP ECC 6.0.
After I compared the two systems I have following questions:
1) there are 4 Software Components which are not in the new system (sap03). This are:
PI
FIN_BLERP
BP_INSTRASS
Is this necesary for the DB copy or we do not need this to be able to do the DB copy?
2) The Software Components Level is not the same. Should we have the same level to do the DB Copy?
Thanks in advance
Best regards
HanseAtik

Hi Juan, hi Clas,
just to be clear and to not stuck on the the way:
The systems are as follow:
1) the source system:
                     - Windows Server 2003,
                     - MSSQL Server 2005 with 32 bit.
                     - Mysap 2004 SR1
2) Target system:
                   - Windows Server 2003
                   - MSSQL Server 2005, with 64 bit.
                   - Mysap 2004 SR1 (with less Support package level and no PI, FIN_Basis, BP_BLERP and BP_INTASS coponents)
I hope this will work. could you post the link the DB Copy guide we are talking about?
By this way we will be sure that we are talking about the same DB Copy. Otherwise any mistake in this step will cost more work and time.
Thanks in advance
Best regards

Using same Wildcard certificate on multiple SAP systems with same domain name.

Hello All,
Need urgent help.
I have a WILDCARD SSL certificate in pfx format. I also have individual root certificate , primary certificate in text form.
The certificate mentioned above is already active in one of our portal.
We want the same certificate on ECC Production.
What are the steps to import this certificate in STRUST?
I believe no certificate response needs to be imported.
I have a certificate response provided by Verisign. But STRUST says- cannot import certificate response'
Please help.

Hi,
This is what i did for installing wildcard certificates:
On the OS of the sap server, log in with the sapadm account.
Open a command prompt:
make a backup of your sec directory in drive:\usr\sap\<SID>DVEBMGS00\ (just to be sure)
cd to drive:\usr\sap\<SID>DVEBMGS00\exe
>sapgenpse.exe import_p12 =p SAPSSLS.PSE location\to\the\certfile.pfx
It will ask you for the pin, and to overwrite the file, answer yes.
Now copy the new SAPSSLS.PSE to a desktop that has sapgui
Login with the sapgui and run transaction strust
Select import from the PSE menu and open the SAPSSLS.PSE
Then again goto PSE menu and select Save As
I saved it twice, once in System PSE and then again in SSL Server
For me SSL is now working without problems on a couple of servers.
-small update-
You can check internal servers using the certificate utility from digicert https://www.digicert.com/util/
It has the option to specify port numbers, usefull for internal web services.

Rolf

Is it OK to have two SBS Servers with same name, on different subnets but connected over a VPN?

Hi Everyone,
I'm just about to connect up two SBS 2011 Servers with the same server name but on different subnets & domains over a VPN.
So for example both servers will have the name Server01, one would have an ip address of 192.168.85.5, the other 192.168.86.5, they both then would be connected over a VPN.
Can anyone foresee any issues with this configuration, like DNS & DHCP requests, adding new machines to the domain, mapping drives etc.
Many thanks,
Nick

Hi Larry & Strike First,
Thank you for your responses. I understand that this is an unusual situation. Basically I've recently taken over the IT support for this client. The client has just had a new phone system installed
& are asking if they can speak to each office internally, which can easily be done once I setup the VPN.
However I noticed whilst looking at this further that the Server names are the same, hence my question?
Am I right in saying that providing the workstations have a trust relationship with their own domain controllers through their individual domains on separate subnets, that hopefully there shouldn't be any DNS issues between the two domains and Servers?
I could build a new VM if you feel it would be better practice to do so?
Many thanks for your assistance,
Nick

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

Two JTrees synchronizeds with same data but one filtering original data

I'm doing a chat and the users are showed in a JTree in mainFrame, with doble clic on a node user is showed a sessionFrame that permit send text message and a button that offers the feature of add another user online, How i can use the original JTree in mainFrame to show the users online in another JTree, but filtering the users (nodes) offline, and thus any changes made in the first JTree come to the second JTree immediately,
Thanks a lot for any suggestion.

Hi Sanjeev,
If Appset transport happend twice, all applications should have come in BW. But in this case only PROFIT AND LOSS has got 2 diff tech names.
Hi Nilanjan.
Yes, both the cubes in Infoarea ( QA system) and we have not faced earlier this problem either in any other environments ( DEV or PROD).
Will DEV system appset transport will help to resolve this issue in QA since DEV & QA has same structure?

What issues we may face in installing a new Prod portal with same SID as existing one

Hello All -
We found some vbs script files in the host of EP Prod system. On confirmation from SAP we deleted those files without any harm to our prod EP system. But customer is still concerned about the security of the system and wanted us build the new EP prod system with same SID.
We approached SAP and they suggested to install a new EP system and do customization rather than performing system copy from existing prod EP system because that may still bring those security threat changes to new EP prod system. (we ll decommission the old EP if everything works fine in new EP)
Now I would like to list all the issues we may face in building a new EP system with same SID as that of already existing one and then doing entire customization again in new EP from Basis team point of view. The following are very few i could think of. Could you please add some other concerns you could think of.
1) Keeping in mind that this EP system is in use for more than 6 years, some of the customization could have been done on lower versions. So could those changes be again exported from Dev and imported into new version of EP we are building now ?
2) Can't add two hosts with same name in DNS Server
3) Can't add two systems with same SID in Solution Manager for calculation of SPS to upgrade new EP

You would have to run ipsinstall and install the new gateway. Make sure to follow the installation instruction for installing a gateway.
After you install the gateway you follow the steps in the link you posted to let the server know there is a new gateway.
Then make sure to restart the gateway and server.

Two SAP system in one host and one oracle software

Hi SAP Gurus,
We want to install Two SAP system (PR1 & PP1) in one host(Prdb05) and one database (Oracle). I dont want to do MCOD.
I am very confuse about what changes i need to make before start the install of PP1. Actually i do not required to install oracle software again. am i correct ?
also i do not required to install oracle client again.am i correct ?
Will it take software automatically ?
In SAP note 350251 they asked me to run ./runinstaller !!! but when we
are not installing software again why we need to to execute that.
Will you please guide us for the same.

Hi , This is what you have to do .
Couple of questions before i answer anything
1) Is your first SAP system installed ?
2) is this High Available system
What Oliver suggested is a valid option on Windows , but not on Unix .
In Unix you might face problems for user,groups because the user for ORACLE_HOME should ideally be ora<SID>, and if you have 2 SID and one ORACLE_HOME , which user will you give ?
So , it is better that you have 2 seperate oracle software installed , 2 seperate ORACLE_HOME , 2 seperate filesystems for oracle software .
Hope you understood , what i am trying to say .
Thanks
