How To Configure TREX Name Server&Port for UDDI Service Registry Settings

Hello Experts,
we are using CE 7.1 SP 4 and I would like to use the trex service in the Service Registry.
I use \NWA\Service Registry Configuration\Service Registry Settings\Keyword Search and want to test the TREX Communication using the Test Connection Button.
If I do so, I receive "Connection to TREX not successful".
When I press the Update TREX button I receive this exception:
com.sapportals.trex.TrexException: TREX Name Server (including back-up servers) is down or not accessable. (Errorcode 7217)
I tried to configure the trex.service with the two parameters: nameserver.address and nameserver.backupserverlist -> tcpip://myhostname.mydomain:30001 (Instance 00).
I am not sure if the port number is correct -> is there a way to lookup the correct port number?
Is there something else I should configure?
Thanks for help, best regards
Thomas

Hi Ganesh,
In order to access the Visual Administrator, go to Start > Programs > SAP J2EE Engine > Visual Administrator. After you login, you will see 2 nodes i.e. Dispatcher and Server. Expand the Server node. Then go to "Services" and expand it. Then go all the way down to "TREX Service". Then on the right hand side, go to the property "nameserver.address" where you will key in "tcpip://<nameserver>:<port>". Then hit "Update" and click on the "Save" button. Then when you go to TRex Monitor, you should be able to see the Name Server running. Hope this helps.
Thanks,
Sri

Can anybody know how to configure Multi threaded server?
Thanks,

Values are just samples only. use what ever appropriate for your environment. Understand each of them before using in production.
alter system set DISPATCHERS="(PROTOCOL=tcp)(DISPATCHERS=3)(CONNECTIONS=1000)"
alter system set shared_servers=100
replace "DEDICATED" with "SHARED" in tns names
Ready to go.
select username,server from gv$session (server should show none or shared)

TREX Name Server Disabled

Hello,
I am running EP6 SP2 Patch29. When I click on System Admin - System Configuration - Knowledge Management - Index Administration and the TREX Monitor. I get a message that <b>Name Server Disabled</b>. The other serivces listed are connected.
I went to the TREX Server and I can open a telnet connect on that server on port 8355, which is what is configured as the Name Server port.
Any ideas why I get Name Server Disabled when I looked at the TREX Monitor?
Thanks,
Keith

Hi Keith,
Check the parameters(Name Server parameters .. if anything is disabled, change it) of TREX Service in Visual Administrator and check the parameters in topology.ini file.
Hope this will solve your problem.

How to configure multiple listeners to listen for the same instance.

Hello everyone,
I am running oracle database 11g and I want information regarding how to configure multiple listeners to listen for the same database instance. Actually I know how to configure more than one listener but the main thing that I am confused about is when we create listener.ora file, do we have to statically register the database instance with both the listeners or the instance will register itself with both the listeners.
According to my knowledge the instance will register with the listener specified by LOCAL_LISTENER parameter and we cannot have more than one value for this parameter.
Please only give detailed answers with example as I am tired of simple answers with details that I already know.

Hello,
Yes, it can make sense to have several listener for one Oracle instance. For instance you may have one listener for the applications another listener for DBA administration tasks as well as one listener dedicated to dataguard broker. It is not possible to have several listeners listening on the same IP and Port.
By default the database try to automatically register to a listener on port 1521. To instruct the instance to register to a specifc list of listeners you can add in the init.ora the local_listener parameter with an alias definition:
i.e
local_listener=MY_SET_OFF_LISTENERS
in your tnsname.ora add an entry called:
MY_SET_OFF_LISTENERS_LOCAL= (ADDRESS_LIST=
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1530))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1531))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1532))
In this sample your instance will register to three listeners listening on respectively port 1530, 1531 and 1532
If you want your clients can be balanced over the 3 listeners

How to configura multiple ldap server to the sun access manager

Hi,
please help how to configure multiple ldap server to the sun access manager, for example access manager does't find the user in ldap1 then it should search in ldap2.
Thanks
Mouli

There�s no need for deleting the default amSDK based datastore because it�s needed for some default accounts.
You may try to create the datastore using the commandline (amadmin)
Have a look /etc/opt/SUNWam/config/xml/idRepoService.xml
You may also try to create amadmin account in the external ldap directory.
(Un)fortunately i�ve never tried to remove the default datastore.
