DISPLAY ENVIRONMENT VARIABLE SETTING

Hi All,
After setting the Display Environment variable and running netca
I am getting below error:
Oracle Net Services Configuration:
java.lang.NullPointerException
at oracle.ewt.lwAWT.BufferedApplet.<init>(Unknown Source)
at oracle.net.ca.NetCA.<init>(Unknown Source)
at oracle.net.ca.NetCA.main(Unknown Source)
Oracle Net Services configuration failed. The exit code is -1
Can anyone tell me what i will do

And TEST-SERVER is the name of your local PC?
the DISPLAY variable needs to be set to the IP of a X-Windows server, the database server will be client to this server!
I know many people here don't know anything about Oracle nor Unix, and also don't want to learn it, and at the same time are SHOUTING all the time.
This is getting terribly annoying.

How to set the DISPLAY environment variable in AIX?Usual format is:
+<host>:<display-number>+
E.g.
export DISPLAY=192.168.0.235:1
Where the host is the hostname or IP address of the client platform running a X-Server. If the X-Server is running locally, then this entry can be omitted.
The display-number is the display number of the X-Server to use. A single X-Server can have multiple displays. E.g. Unix server running a X-Server can have 10 users connected via X-Terminals and will this have 10 displays.
Judging from X-Windows questions asked on OTN, it seems to be a tad complex to grasp for some - especially those from a MS Windows background as X-Windows is very different and also reverses the client-server concept, requiring the X-Server component to be running on the client platform (where the server platform runs the program that is the X-client).
So it is a lot easier to rather use something like VNC instead - supported on most Unix platforms, Linux, Windows and Apple's OS/X.
Simply run the VNC server on the server platform to create a virtual container for running the X-server display. Connect from a client using a VNC client.
As it uses the RFB (Remote Frame Buffer) protocol, it is a lot faster than running the slower and larger X11 protocol required for X-Windows connectivity over TCP/IP.

Environment variable setting not working in the report

Hi everybody,
Iam facing a problem related to reports10g ids. database is 9i
My basic requirement is ,i want to show a report out put in a BRAZILIAN PORTUGUESE Language.
For this purpose i configured the report_server.conf file like
<environment id="PS">
<envVariable name="NLS_LANG" value="BRAZILIAN PORTUGUESE_BRAZIL.WE8MSWIN1252"/>
</environment>
After that i added a entry along with the web.show_documents(using for calling the report)envid=PS
when iam running the report ,report server is only converting one date field in to portuguese ,rest of them are same as in the database.
Actualy i dont know where i did wrong.if anybody know please help meee
Thanks in advance
mathew

Hello Matthew,
See Note:231051.1, Dynamic Environment Switching In Reports 9i for an example of setting your environment variables at runtime. It uses REPORTS_PATH, there is also an entry for NLS_LANG in the reports.sh file (in UNIX). This setting is causing the conflict when you try to set it at runtime.
I think you have to remove the entry from reports.sh config file and then you will have to pass the parm at runtime everytime.
I hope this helps!

Oracle environment variable setting for mulit instances

Dear experts,
I am doing CRM_ABAP, CRM_JAVA,ERP installation based on Oracle in a laptop for SAP Best Practise.
The CRM_ABAP installation have done, and start to install CRM_JAVA named CRJ.
In CRM_ABAP installation, I set Oracle environment variable as below:(/etc/profile.d/oracle.sh)
・CRACLE_SID=u201DCRMu201D
・CRACLE_HOME=u201Doracle/CRMu201D
・PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/bin/oPatch:$PATH:
・export CRACLE_SID CRACLE_HOME PATH
My question is that how do I set environment variable for CRM_JAVA(CRJ) in oracle.sh,?
I tried e.g. CRACLE_SID=u201DCRMu201D:u201DCRJu201D, CRACLE_HOME=u201Doracle/CRMu201D:u201Doracle/CRJ/102_64u201D
or CRACLE_SID=u201DCRJu201D CRACLE_HOME=oracle/CRJ/102_64u201D export CRACLE_SID CRACLE_HOME
in addition
but got an error message in SAPinst (Task Progress: configure Oracle server network)
said u201CAssertion failed:lsnrctl:Parameter dbHOME has to be a valid ORACLE_HOME).u201D
kindly help me to reslove the issue.
Thanks.
regards.
Li.etsuhin

Setting a Linux environment variable like ORACLE_SID to multiple values will not work.
Use another oracle.sh, and maybe also another Linux user.
I am not familiar with the details, but what does your installation guide say?
Or you may have to use the same values for Java. The installation guide will tell you.

SAPDBHOST Environment Variable Set Incorrectly

Hi,
I'm trying to rename a system , with same SID , to work on another partition with a different host name. When I sign on as SidOFR and WRKENVVAR I see the environment variable ,SAPDBHOST, is still set to the old name even though I changed the R3sid400 data areas.
Is there another place this variable could be picked up from - does R3inlpgm play a role in this ?
Thanks

Hi David,
did you change the start profile as well ?
You should adjust the system number in the instance profile as well.
In 6.40 in my eyes, the dtaara R3REE400/R3_07 is still in use:
           Wert
Offset      *.......1.......
    0      'DVEBMGSs2qa
   50      '
100      '
Did you really change the contents to the new data ? (here: s2qa)

Environment variable set in Inplace Migration

(a) Set OLDSYBASE to your pre 12.5 release directory.
(b) Set your OLDSYBASE_ASE to your ASE component version ONLY if you are
    upgrading from ASE 12.0 version and above.
    For e.g., set OLDSYBASE_ASE to ASE-12_0 if you are upgrading from ASE 12.0
    If you are upgrading from 11.9.X and below, set OLDSYBASE_ASE to NULL value
(c) Set your OLDSYBASE_OCS to your Opent Client/Server Library version ONLY if you are
    upgrading from ASE 12.0 version and above.
    For e.g., set OLDSYBASE_OCS to OCS-12_0 if you are upgrading from ASE 12.0
    If you are upgrading from 11.9.X and below, set OLDSYBASE_OCS to NULL value
Please guide where to set environment variable . I am not linux proficient

Hi Santosh,
Please keep in mind that this Comunity is for SAP applications running on ASE.
By the release of ASE, you are not using SAP applications I would suggest to post a discussion on comunity "SAP ASE for custom applications" Comunity -> http://scn.sap.com/community/ase-custom-applications
Just a quick reply. It will depend which shell are you using but basically you can use one of them:
- export command:
<VARIABLE_NAME>=<value>
export <VARIABLE_NAME>
- setenv command:
setenv <VARIABLE_NAME> <value>
setenv OLDSYBASE <old_$SYBASE_directory>
setenv OLDSYBASE_ASE ASE-12_5

$PATH environment variable setting

This question is for the Terminal.app UNIX wizards out there. I'm wondering where the default $PATH variable setting is established by the operating system. I know I can modify this variable's setting in my .bash_profile or .profile files, but that isn't what I'm after. Where does the OS get the default settings for this variable?
Many thanks.
PowerMac G5 Mac OS X (10.3.9)

Try looking in the /private/etc/profile file.

Java displays not being redirected to the DISPLAY environment variable

I am running Solaris 8 and am using java se 1.4.1.
I have a java application that is running in the background on BOX 1. It needs to use the JOptionPane.showmessage() function.
When I remote onto Box 1 from Box 2, and run the java application, the message boxes from the JOptionPane.showmessage() are displayed on Box 1 instead of getting redirected to box 2. I know that the display setting are ok, since I can start other applications and get the displays sent to box 2.
Is this a java bug?
thanks
Ben

Hi Balus,
Thank you for your reply, yes the response is absolutely empty just an empty page like:
<html><body></body></html>In the logs I can see the normal trace about the error but nothing else.
I found a "solution" that is working fine but I'm not sure if is the best to do, basically
I'm throwing again the ServletException generated in the JSP an then is working:
void autoForward(String forwardTo, HttpServletRequest request,
            HttpServletResponse response, ServletContext servContext,int errorCode)
            throws ServletException {
        try {
            addErrors(request,errorCode);
            RequestDispatcher dispatcher = servContext.getRequestDispatcher(forwardTo);
            dispatcher.forward(request, response);
        } catch (ServletException ex) {
            throw new ServletException(ExceptionUtils.getRootCause(ex));

Where is my PATH environment variable set in Mavericks

I just did a fresh install of Mavericks 10.9.1 and I'm about to setup for a Laravel 4 workflow (install Homebrew & enable mcyrpt).
I have revealed all hidden files and I see no .bash_profile or .profile files in my User root folder. So how can I change my $PATH variable without a .bash_profile file? Can I just create .bash_profile and it will read it? also does .bash_profile have to be plain or rich text?
Thanks.

Create the .bash_profile in your home directory as a plain text file.
Use an editor like TextWrangler which a a good programing and system editor.

And what did you configure at the side of 192.168.100.159 which is supposed to be your client?
I suggest you run VNC server on the server side ('vncserver') and set $DISPLAY to that. Next, use VNC viewer on your client machine to connect to the VNC server.
Unless you have an X server running on your client machine of course.
