Unable to create Inbound Sync Server Proxy - Authorization problem

Im using PI 7.0  . When I try to create a inbound sysnchronous server proxy in SPROXY tcode , I get the following error
Authorization Check failed: S_TCODE with parameters TCD SICF
Im able to create both outbound and inbound asynchornous proxies . What could be the problem?

The JDK/Java that ODI using should be 64bit if ODI 11.1.1.6 is 64 bit.   (I think JDK 1.6 is recommended for this ODI version)
Also, for which technology you are creating a data server ? and what error message you are getting while creating it ?
Thanks,
Santy.

  • POST fails on T5140 server.   POST shows errors about "Unable to create files".  Server won't boot

    All,
    Need any help that someone can provide.  Currently I have a T5140 server.   Yesterday it crashed unexpectedly. We were able to reboot the system and it come back up with the service light on.  Service light was indicating a memory DIMM problem.   We powered down the server to replace the memory modules that had service led showing for them.   After powering the system on, it never gets past POST now.  We attached a serial console to the ILOM and watch the post.   POST starts normally. Then we start to see messages about "unable to create files.  Finally POST gets to a point where it looks like it is finishing but hangs.   It hangs at the point where it say that it is initiating run level 3.  But it just sits there and never boots the system.  Any ideas?   Is this a motherboard issue that really cemented itself when the power was removed to the system?  Any help would be greatly appreciated.  We are stuck.
    Thanks.

    I have had this same issue, unfortunately you will need to place a service call for a field tech to come on-site and replace the failty DIMM. The T5140 WILL NOT BOOT if any one or more DIMMs fail to POST.
    The only partial solution is to disable the CPU that is connected to the bad DIMM so the system will successfully boot up in degraded mode. But I would not run the box like that for long.
    You need to call service a.s.a.p.

  • ODBC error generating temp file: "Unable to create file buffer" Server 2008

    Guys:
    I have a 32 bit application that has been running for years with no problems under XP and MS Server 2003.
    To access the oracle DB we use MFC drivers and ODBC system datasources for Oracle 10g and 11g.
    We recently moved from MS Server 2003 to Server 2008 Standard Edition (32 bit).
    We also upgraded our DB from 10g to 11g R2.
    Now the application gets intermittent errors when accessing the database like the one below:
    "Unable to create file buffer"
    I looked this up on other forums and it seems to be a problem with the ODBC driver creating uniquely names temp files
    in the system temp folder. This was a documented problem some years ago and was fixed but now seems to have
    reared its ugly head for Server 2008.
    I'm not sure who the culprit is: 2008 32-bit or the 11g drivers.
    I just know that some of our transactions fail because ODBC has problems and this is killing us.
    As you see we are still running on a 32 bit OS and have created the ODBC DSNs using odbcad32.exe.
    The application connects to the DB and works MOST OF THE TIME but random transactions now fail because of this error.
    If I try to kill all of the *.tmp files from the windows temp directory it seems to solve the problem for a while but then the problem comes back rather quickly.
    Any help here would be apprciated.

    This may solve the issue: http://support.microsoft.com/kb/130719
    Don't just delete the offending file...it will be recreated eventually. Post a dummy file to prevent the error from reoccurring.
    My only question is why you put more info on database and ODBC versions here and not in your SR? I'll note this in your SR for ya ;)

  • Unable to create a linked server that points to an availability group listener.

    I don't even know if this scenarios is supported or not, I can't find any documentation on it.
    I have a couple SQL 2012 servers setup using AlwaysOn Availability Groups.  The listener (SQLAG1) is setup and working as expected with applications.   The 2 machines are in different subnets, so we are using the MultiSubnetFailover=True on the
    connection strings to ensure that failover works. 
    From an SQL 2014 box I want to create a linked server that points at the Listener.   I'm able create the linked server, but it appears like sql server is not using the MultiSubnetFailover=True and it fails to connect.  Here is what I used to create
    the linked server;
    EXEC sp_addlinkedserver
    @server = N'SQLAG1',
    @srvproduct = N'SQL2012',
    @provider = N'SQLNCLI11',
    @datasrc = N'SQLAG1',
    @provstr = N'Provider=SQLNCLI11.1;Data Source=SQLAG1;MultiSubNetFailover=True',
    @catalog = NULL
    GO
    Do anyone know if this is supported?  if so what it proper way to create the linked server?  
    Thanks!!!

    Thank you.   
    OLE DB in the SQL Server Native Client does
    not support the MultiSubnetFailover keyword.

  • Unable to create a sync account

    I can't create a Sync account. I have never had one and am trying to set one up so that I may sync my firefox with my android. I have followed the instructions to set one up but when I push the finish button, I don't get a window that says setup complete. I have tried several times.

    You're welcome
    Did you find the cause?
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    *Use "Disable all add-ons" on the [[Safe Mode|Safe Mode]] start window to disable all extensions.

  • Unable to create application module.  JNID/RMI problem?

    Hi forum,
    I've got an ADF/OC4J application deployed and running successfully but sometimes the following error comes up:
    JBO-30003: The application pool (com.miempresa.AppModuleLocal) failed to checkout an application module due to the following exception:

    Thanks in advance for your help.

  • Unable to create a reports server to test web.show_document in Forms 10.1.2

    Hi all,
    In Forms 10.1.2 DS, I'm trying to use the web.show_document built-in to 'generate' a report from a .jsp file. This JSP file was created by wizard through creating a report object in the Object Navigator. The code I'm using from a push button is as follows:
    web.show_document('http://<hostname>:8889/reports/rwservlet?report=<dirpath>\Sales.jsp&userid=<username/password@connectstring&server=<server_name>'
    As far as I am aware no 'reports server' has been created so I've tried the following command in a dos window:
    rwserver -install <server_name>
    but this just raises an 'alert' indicating that I should consult an installation guide to setup and install the server. So my questions are:
    (1) Is what I'm trying to do supported in DS?
    (2) What installation guide should I consult?
    Any information on this would be gratefully appreciated,
    Kevin.

    Hi Inol,
    Thanks for the response. I agree with the comment about exposing user details, I'm just doing a bit of experimenting at the moment! I tried to do what you suggest in terms of changing the URL but whether I reference the server or leave it out, the subsequent browser session seems to hang and then eventually I get a 'Page Not Found' response. On using the URL 'http://127.0.0.1:8889/reports/rwservlet/showenv?', I get an 'Access Denied' Error Page. Is there something additional I need to set up with regards to Reports to get this to work?
    regards,
    Kevin.

    Well... this ALMOST worked. I got closer. I found out there are three cacaoadm deamons on the machine, so, I started the correct one at this time:
    [server1]/opt/myuser> ps -ef | grep cacao
    root 17773 1 0 Jun 12 ? 0:02 /usr/lib/cacao/lib/tools/launch -w /var/cacao/instances/default -L 16384 -P /va
    myusermx 22756 20845 0 10:06:14 pts/4 0:00 grep cacao
    So, I stopped the old one:
    root@server1 # cd /usr/sbin
    root@server1 # ./cacaoadm stop
    root@server1 # ps -ef |grep cacao
    root 23393 23045 0 10:16:20 pts/4 0:00 grep cacao
    root@server1 #
    Then I changed to the location of the correct one
    cd /opt/myuser/sunoneldap/dsee6/cacao_2/usr/sbin/
    [server1]/opt/myuser/sunoneldap/dsee6/cacao_2/usr/sbin> ./cacaoadm set-param network-bind-address=<my_ip>

    So, I went back to the console, at this time it let me thru the step to accept the certificate, I did click next and an exception was threw. I copied it, but I lost it. After that, I wasn't able to get to the same point again, I am back to the old message that it can't contact the cacaoadm....
