WebLogic 10.3 and Kerberos

Does WebLogic Server 10.3 require that Kerberos preauthentication be enabled or disabled? I have a system that is experiencing some intermittent authentication issues. The Active Directory Authenticator is setup in WebLogic and my AD users can successfully authenticate in most cases. To help limit the size of the Kerberos ticket, I have preauthentication disabled (refer to http://support.microsoft.com/?kbid=832572 for more info). Just wondering if this might be causing my authentication issues with WLS....

Preathauthenticaition doesnt need to be enabled. You can rule this out as the cause of the issue.
Do you have the log files and tcp dump of the time when authentication fails?
That would give us a good idea.

Is Weblogic 11g supports for Kerberos AES/RC4 Encryption on Windows 2008 R2

Is Weblogic 11g supports for Kerberos AES/RC4 Encryption on Windows 2008 R2?
Thanks,

DES is disabled by default on 2008, could this DC be a Windows 2003? If so then this would be the expected encyption.
The following is the list of the encryption available for each Windows system
Windows 2000, XP,Windows Server 2003:
DES, RC4
         Vista
, Windows Server 2008:      DES, RC4,AES
         Windows 7 and Windows Server 2008 R2:     DES(disabled by default), RC4,AES

Help!.... XA error: using Weblogic 6.1 and Oracle 8.1.6

 Hi,
 I am using Weblogic 6.1 with Oracle 8.1.7. I configured a TXDataSource as I wanted
 to use Container Managed Transaction through a Session Bean.
 Connection Pool Settings: -------------------------
 Name - myXAPool URL - jdbc:oracle:thin:@myServer:1521:myDb DriverClassname - oracle.jdbc.xa.client.OracleXADataSource
 TXDataSource Settings : -----------------------
 Name - myXADS
 JNDIName - myXADS
 PoolName - myXAPool
 Everything works fine but once in a while I get the following exception:
 java.sql.SQLException: XA error: XAER_RMERR : A resource manager error has occured
 in the transaction branch start() failed on resource 'myXAPool' Unexpected error
 during start for XAResource 'myXAPool': null
 The connection pool size is 30 and the number connections high reached was 5,
 which means there are enough connections in the pool available at all time.
 It would be really great if you can help me out.
 Thanks in Advance, Sudhir.


Hi Slava,
Sorry about that Oracle instance I am using is 8.1.7.
For the XA Driver I am using the one that comes with Weblogic in weblogic.jar.
And my Weblogic version 6.1 Sp3.
Thanks,
Sudhir.

CF8 on Weblogic 10.0 and Apache

I am trying to configure CF8 as an EAR file on Weblogic 10.0
and configuring it with Apache webserver. The settings for Weblogic
are made as mentioned in the configuration document and CF8 is
working fine on Weblogic.
Now for Apache connectivity, a connector is configured for
Weblogic which handles *.cfm files requests as well.
- The CFM files are kept in webserver and when I try to open
a cfm file, the proxy is getting invoked but since Weblogic doesn't
find the file URI it returns 404.
- Please let me know how can the CFM files kept on Webserver
be rendered using CF8 deployed on Weblogic
Or there is a need for these files to be kept on the Weblogic
Appserver only

Sure. If you want to put a file example.cfm in a WAR file,
put it in the
root of the WAR. Your folder structure will look something
like:
WAR/
WAR/example.cfm
WAR/WEB-INF
WAR/WEB-INF/web.xml
WAR/WEB-INF/*
WAR/WEB-INF/cfusion
WAR/WEB-INF/cfusion/lib/
etc.
Then if you have a context root "/test" in your
Application.xml you can
reach your template through the URL
http://server/test/example.cfm
The best way to get a WAR (or EAR) file for deployment is to
run the
installer. It has the option to generate a WAR or EAR for
you. Use that,
then later unjar it to see how it looks internally.

WebLogic 8.1SP4 and IIS

Hi,
I want to configure weblogic with IIS and have found enough articles on how to proxy IIS to point to a single instance or a clustered environment but not on how to proxy IIS to multiple WebLogic servers
I have the application running on
http://<weblogic-server>:7201/elms
http://<weblogic-server>:7301/elms
http://<weblogic-server>:7401/elms
and I want to be able to access these via the IIS through these URLs:
http://<IIS_Server>/elms
http://<IIS_Server>/elms_sit
http://<IIS_Server>/elms_uat
Is this configuration possible? Any help would be highly appreciated.
Thanks
Sandeep

Since you are attempting to proxy by path you need to configure the iisforward.dll as stated in step #3 here:

Weblogic Bridge "failed and will reconnect later"

The enterprise architecture is as follows:
1 Physical machine where I have 2 VMs on this machine, and each VM I have 1 domain, 1 Cluster and 1 managed server, and the second VM I have the replicated what I have in first VM.
In first domain I have the OSB, in the second domain I have SOA.
What I need ? Send information of queues (topics) of First Domain (OSB) to second domain(SOA).
At first the only thing I did was:
In the first domain I created OSB JMS Server, JMS Module, Connection Factory and Queue Topic.
In the second domain SOA I replied the same thing but with different names.
Then I created the bridge with configuration default between the first domain and the second domain, the bridge and when active it generates me a message Weblogic Bridge "failed and will reconnect later"
I did a test on my local machine windows where I created two domains, and the same procedures you did above, but the point was funcinou been activated now for the enterprise environment I'm not managing to make it work, you could tell me what is wrong . in both cases restarted the weblogic server as the machine itself the question that ran on my machine and machine company no.
If you can give me a light thank.

10.6.6 Server Combo Update Crashes LDAP and Kerberos Services

Just updated apple server from 10.6.4 to 10.6.6 with combo server overnight.
Everything was working fine under 10.6.4
All users can no longer authenticate to server via mail or ldap logins
LDAP and Kerberos Services stopped.
Will downgrade from an open directory master to standalone then back to master again and post status...

I think there is something with LDAP on 10.6.6
I was forced to make clean install in combo from 10.6.0 to 10.6.6 and today LDAP crashed.
It seems to be an issue on ldap ACL.

Configure CRS2008 to using AD and Kerberos with Java application servers.

Hi All,
I have configure CRS2008 to using AD and Kerberos with Java application servers. Domain Controller is installed on W2K3 Server. In addition, CRS2008 is installed on another W2k3 Server.
I have create service account in domain controller: CMSACC
I have create two user account: CRuser1 and CRuser2
I have create domain group: CRSGroup
After I had run the setspn in domain controller,I got the message at below:

Default AD Domain: BD.com
Add AD Group(Domain\Group): secWinAD:CN=CRSGroup,OU=TEST,D=BD,DC=com

I have create a WINNT folder in root directory.Moreover and save bcsLognin.conf and Krb5.ini at here.
bscLogin.conf:

I have tested the Kerberos,using kinit CMSACCatBD.com password, and got error message at below:

My problem is failed to logon CMC and infoview and got error message at below:
Account Information Not Recognized: Active Directory Authentication failed to log you on. Please contact your system administrator to make sure you are a member of a valid mapped group and try again. If you are not a member of the default domain, enter your user name as UserNameatDNS_DomainName, and then try again.
Actually, I am sucessful to logon Business View manager with CRuser1. However, I fail to logon CMC and infoview and got the above error. Have you any suggestion to solve this problem?
Ken.

if you can logon with client tools then that should be an indication that the service account running the CMS IS working! Good news.
So the problem is likely with the java portion (krb5/bsclogin or java options)
If the files are in c:\winnt\ (if not copy them there) and perform c:\program files\business objects\javasdk\bin\kinit username
then enter and password/enter again
Probably get the same message. To note in your krb5.ini all domain info must be in CAPS (the .com appears to be in lower case)
kinit works with just the krb5.ini, java SDK and AD (removing BO config and the service account from the picture). Once that works if your java options are specified properly you should be able to login to CMC/infoview.
also 1 last point. Add udp_preference_limit = 1 to the krb5 lib defaults section
libdefaults
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
udp_preference_limit = 1

Tim

Preview Release of WebLogic Portal 9 and Workshop 9

I would like to get my hands on a developer preview release of WebLogic Portal 9 and Workshop 9. I can't seem to find it online so I'm hoping someone can point me in the right direction. We're currently evaluating portal products and I would hate to decide against BEA based on the lack of availability of the forthcoming version.
Anybody know where a developer release of either of these two products can be found?

The Technology Preview for WLP 9.x and WLW 9.x will be available in early December. Please contact your BEA account team to let them know that you are interested.
At present the plan is to have a GroupSpace community site for use by all customers participating in the Technology Preview. A BEA technical field staff member (SE, PS, etc.) assigned to your account will use this site to send you an invitation, and when you join you will have access to the installation. Questions, discussions, etc. for the Technology Preview will all go through the GroupSpace site. If you don't know who your BEA technical account member(s) are, you should find out as they will be the key to obtaining the Technology Preview.
If you can't wait for the Technology Preview, please ask your BEA acount team to contact myself or others in Product Management. We'll be happy to go over the product features, show you demos from current builds, etc.
Thanks,
Skip Sauls
Senior Product Manager, WebLogic Portal

Weblogic 8.1 and Novell LDAP SSL

You need to configure the server SSL to trust the identity certificate it receives
from nastea02.bankofny.com If you want to use the default configuration you could
simply import the CA certificate that issued that identity certificate to the
DemoTrust.jks keystore.
Also, look at Using Host Name Verification here: http://edocs.bea.com/wls/docs81/secmanage/ssl.html#1187786
because this might be another reason why the certificate is rejected.

How to run weblogic 8.1 and weblogic 9.2 simultaneously

I have data service platform installed on Weblogic 8.1 platform and Aqualogic service bus installed with Weblogic 9.2.And I want to start both the servers at the same time.
I have configured Weblogic server 8.1 domain to listen on 7771 port while weblogic 9.2 server domain is listening on 7001.However when I start both the server then one server starts and others server fail to start and in prompt following error message is displayed :

Can you show us the full error message? I don't know of anything in WLS that uses port 202 by default. It's a privileged port as well which makes it even more unusual.

Performance of Weblogic 4.03 and Visual Age 2.0

Hello,
I am experiencing severe performance problems when running Weblogic 4.03 and
Visual Age 2.0. The server runs extremely slowly in this environment,
however, the 3.13 version did not suffer from this. Has anyone else noticed
this? Is there anything I can do about it?

Has anyone else noticed this? Is there anything I can do about it?You can set the following undocumented property in weblogic.properties:
weblogic.system.gc.intervalSecs=5
There's some kind of bad interaction between Visual Age and WebLogic's
garbage collection control. Basically, there's a garbage collection
task that by default runs once a second, and in the Visual Age VM,
something it's doing takes more than a second.
The problem only seems to exist in WebLogic 4.0.3. It doesn't happen in
4.5.x. Also, according to one report I've had, you may need to set the
property value to more than 5 on slower machines.
Note that this property is unsupported, and is not guaranteed to even
exist in any other version of WebLogic.

Weblogic 4.5 and Visual Cafe 3.1

Hi,
I am having a problem integrating Visual Cafe with Weblogic.
Specifically, it involves getting the Weblogic classpath modified to support
setting up a connection pool to an Informix database. If I start the
Weblogic server manually, I can set the server classpath appropriately to
find the Informix JDBC driver and my pool is setup properly.
However with VC, it starts the Weblogic server from the IDE and I have
not been able to get the addition classpath entries to find the Informix
driver. Is there a way to add additional classpath entries so that when VC
starts Weblogic it will find my JDBC driver? Or do I have to start the
Weblogic server seperately and setup remote debugging manually?
Thanks
Carl

If you don'y use the symantec debug VM, it stands to reason that the debug
environment will not see your process in the VM. I can't help you with why your
WL crashes when you connect using the debug VM. Perhaps you could post some more
information?

Hey,
help please
You said that you can attach from VC 3.1 to weblogic server 4.5.1 right. How
did you start the server ? Is it using the symantic debugvm.exe and symantic
settings? If I start the server with javasoft java.exe then VC is not seeing
the vm at all. And I tried starting weblogic server using symantic
debugvm.exe, as soon as a client trying to connect then the server crashes.
Please post the some instruction how did you do that?
Thanks

The latter has been successful with me. I start the WL server manually viaa
command prompt and then 'attach to process'.

Hi,
I am having a problem integrating Visual Cafe with Weblogic.
Specifically, it involves getting the Weblogic classpath modified to
support
setting up a connection pool to an Informix database. If I start the
Weblogic server manually, I can set the server classpath appropriatelyto
find the Informix JDBC driver and my pool is setup properly.
However with VC, it starts the Weblogic server from the IDE and Ihave
not been able to get the addition classpath entries to find the Informix
driver. Is there a way to add additional classpath entries so that whenVC
starts Weblogic it will find my JDBC driver? Or do I have to start the
Weblogic server seperately and setup remote debugging manually?
Thanks
