How to configure tns listener to access remote application?

Hi all,
Hope doing well,
sir i am trying to access host database in my client system. both are connected with the same network through LAN.
i have installed oracle client in client system. but when i running web application getting this error: ORA-12541: TNS:no listener
i have googled for that and i got that if in tns.ora file we set the ip address of client system instead of localhost it will work.
i changed that in my tns.ora file which is here
# tnsnames.ora Network Configuration File: C:\app\securax\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
GRAND1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.4)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = Grand1)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
LISTENER_GRAND1 =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
but still getting same error.
how to come out from this error?
thanks

ADR_BASE_LISTENER = C:\app\securax
when i am using this command "lsnrctl start Grand1"
it is telling the listener of the name LISTENER is already started.
means it's telling about that listener which is in listener file not in tns.ora file.
so this is correct or not?
thanksits wrong you don't have listener with name called Grand1 , your listener name is LISTENER

How to configure oracle listener profile for multiple oracle database

Hi,
I am going to install solution manager system in the same server of ERP EHP4 on Windows. Both DB are oracle.
I'd like to know how to configure listener in this kind of envirnmonent.
a. use two listener and different ports
b. use same listener but different ports
c. use same listener and same port
Which is the correct mothed?
And, after installation, there seem three set of profiles of listten, one for ERP, one for SLM, and the other for OS?(%windir%system32), which one is functional?
Please advise.
Thanks a lot.
Regards,
Alex

Hi,
standard installation is creating new configs for listener for each instance.
I would recommend to use one listener per each instance.
YOU CAN NOT HAVE one port number for two differnet systems!
If you want to use one listener than you must adapt tnsnames.ora, listener.ora and ensure that both systems will use different port numbers.
For example PORT= 15<system number>

How to configure oracle and ms-access db

Hi All,
I have a requirement to push data from the oracle to ms access. My oracle database is on the Unix server and ms access is on my local desktop. Is there a way to configure if so how to configure both the db? Basically I am wanted to make the ms access visible to oracle so that I can use the Heterogeneous package. Please let me know if there are any different ways.
my oracle version is
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
ms-access 2007
Thanks in advance.

Hi,
You could use the Database Gateway for ODBC (DG4ODBC) to do this. It uses a third party ODBC driver to make the connection to MS-Access so the best option would be to install it on the Windows machine where Access is running and use the Microsoft Access driver.
Otherwise, you could install on Unix where Oracle is running but I don't think there is third party Access driver for Unix.
The following note available in My Oracle Support describes the setup on Windows -
Note.466225.1 How to Setup DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit
You should install the latest 11.2 DG4ODBC and this note has pointers to the download sites -
Note.1083703.1 Master Note for Oracle Gateway Products
DG4ODBC can be installed standalone without an RDBMS being installed.

LDAP support limited. How to configure Address Book / Directory Access?

I complained to a sysadmin that my LDAP searches were returning very limited information (just surname and e-mail). He replied,
"...[Address Book] can't be configured to query specific attributes, it can't be configured to show specific attributes except for the small set they have elected to permit, ... it doesn't even show cn/commonName which is a compulsory field in the inetOrgPerson schema or ou/organizationalUnitName which is the standard way of distinguishing components of an organization..."
Directory Access seems to offer facilities for requesting specific attributes. I tried mapping them to Address Book fields, but with no improvement in the search results. Any tips?

Here is some info I found on manually configuring and mapping schemas.
Configuring LDAP Searches and Mappings
Using Directory Access, you can edit the mappings, search bases, and search scopes that specify how Mac OS X finds specific data items in an LDAP directory. You can edit these settings separately for each LDAP directory configuration listed in Directory Access. Each LDAP directory configuration specifies how Mac OS X accesses data in an LDAPv3 or LDAPv2 directory.
You can edit the mapping of each Mac OS X record type to one or more LDAP object classes.
For each record type, you can also edit the mapping of Mac OS X data types, or attributes, to LDAP attributes.
You can edit the LDAP search base and search scope that determine where Mac OS X looks for a particular Mac OS X record type in an LDAP directory.
IMPORTANT: When mapping Mac OS X user attributes to a read/write LDAP directory domain (an LDAP domain that is not read-only), the LDAP attribute mapped to RealName must not be the same as the first attribute in a list of LDAP attributes mapped to RecordName. For example, the cn attribute must not be the first attribute mapped to RecordName if cn is also mapped to RealName.
For detailed specifications of Mac OS X record types and attributes, refer to "Mac OS X Server Open Directory Administration for Version 10.4 or Later" (available at www.apple.com/server/documentation/).
In Directory Access, click Services.
If the lock icon is locked, click it and type the name and password of an administrator.
Select LDAPv3 in the list of services, then click Configure.
If the list of server configurations is hidden, click Show Options.
Select a server configuration in the list, then click Edit.
Click Search & Mappings.
Select the mappings that you want to use as a starting point, if any.
Click the "Access this LDAPv3 server using" pop-up menu and choose a mapping template to use its mappings as a starting point or choose Custom to begin with no predefined mappings.
Add record types and change their search bases as needed.
To add record types, click the Add button below the Record Types and Attributes list. In the sheet that appears, select Record Types, select one or more record types from the list, and then click OK.
To change the search base and search scope of a record type, select it in the Record Types and Attributes List. Then edit the "Search base" field. Select "all subtrees" to set the search scope to include the entire LDAP directory's hierarchy from the search base down. Select "first level only" to set the search scope to include only the search base and one level below it in the LDAP directory's hierarchy.
To remove a record type, select it in the Record Types and Attributes List and click Delete.
To add a mapping for a record type, select the record type in the Record Types and Attributes List. Then click the Add button below "Map to __ items in list" and enter the name of an object class from the LDAP directory. To add another LDAP object class, you can press Return and enter the name of the object class. Specify whether to use all or any of the listed LDAP object classes by using the pop-up menu above the list.
To change a mapping for a record type, select the record type in the Record Types and Attributes List. Then double-click the LDAP object class that you want to change in the "Map to __ items in list" and edit it. Specify whether to use all or any of the listed LDAP object classes by using the pop-up menu above the list.
To remove a mapping for a record type, select the record type in the Record Types and Attributes List. Then click the LDAP object class that you want to remove from the "Map to __ items in list" and click the Delete button below "Map to __ items in list."
Add attributes and change their mappings as needed.
To add attributes to a record type, select the record type in the Record Types and Attributes List. Then click the Add button below the Record Types and Attributes list. In the sheet that appears, select Attribute Types, select one or more attribute types, and then click OK.
To add a mapping for an attribute, select the attribute in the Record Types and Attributes List. Then click the Add button below "Map to __ items in list" and enter the name of an attribute from the LDAP directory. To add another LDAP attribute, you can press Return and enter the name of the attribute.
To change a mapping for an attribute, select the attribute in the Record Types and Attributes List. Then double-click the item that you want to change in the "Map to __ items in list" and edit the item name.
To remove a mapping for an attribute, select the attribute in the Record Types and Attributes List. Then click the item that you want to remove from the "Map to __ items in list" and click the Delete button below "Map to __ items in list."
To change the order of attributes displayed in the list on the right, drag the attributes up or down in the list.
Click Save Template if you want to save your mappings as a template.
Templates saved in the default location are listed in pop-up menus of LDAP mapping templates the next time the current user opens Directory Access. The default location for saved templates is in the current user's home folder at this path:
~/Library/Application Support/Directory Access/LDAPv3/Templates
Click Write to Server if you want to store the mappings in the LDAP directory so that it can supply them automatically to its clients.
You must enter a search base to store the mappings, a distinguished name of an administrator (for example, uid=diradmin,cn=users,dc=ods,dc=example,dc=com), and a password. If you are writing mappings to an Open Directory LDAP server, the correct search base is "cn=config, suffix" (where suffix is the server's search base suffix, such as "dc=ods,dc=example,dc=com").
The LDAP directory supplies its mappings to Mac OS X clients whose custom search policy includes a connection that's configured to get mappings from the LDAP server. The LDAP directory also supplies its mappings to all Mac OS X clients that have an automatic search policy. For instructions, see Configuring Access to an LDAP Directory and Setting Up Search Policies.

How to configure JMS listener in separate jvm

Hi Guys,
I am new to this forums so please let me know if iam making any mistake.
I have 2 instances of tomcat running on different port numbers. I am using apache ActiveMq as my message broker for sending the jms message using queue. Code for sending the message is present in a servlet. So when I run that servlet message gets sent.
In my other tomcat i retrieve this jms message. But for me issue is this messsage gets retrieved only if i write this code in a servlet and I run that servlet.
Is there any way where i can configure a listener for my class present in tomcat 2. So that when message gets sent that piece of code gets triggered automatically and I can read that message.

Sounds like you want basic JMS message consumer functionality.

How to configure roles at runtime without changing application code?

Hi,
We have implemented Custom Login Module security for our application. Our requirement is to configure the roles without changing the application code.
Our Authentication Type is 'JAAS With Custom Login Module' and Authorization Type is 'JAAS'.
According to 10.1.3 section of JhsDevGuide1013.pdf, we need to configure the roles in web.xml and also need to give the role in the 'Authorized roles/permissions' section of the group.
We dont want to change the application definition once we go live just for adding roles. That is overhead for us as we may need to configure more roles according to our business requirements, but each time we dont want to change the code and re-deploy the application.
Please let us know the way to meet our requirement.
Thanks in advance.
Thanks & Regards,
Ramakrishna. P

Hello,
The JHeadstart Developers Guide has an excellent chapter about security to answer questions like these.
For example, you could use the JHeadstart based custom security, with datatables, that will enable you to add roles and users at runtime.

How to configure different listener for each database in 11gR2 RAC

Hi Friends,
Current Prod Setup :
11gR2 (11.2..0.2) RAC on RHEL 5.5 with 3 SCAN Listeners on default 1521 port.
Having 4 databases which are using SCAN-IP and listening on default port only.
As per policy, we have to create separate listeners (on different port) for each database.
like,
DB1 - 1522
DB2 - 1523
DB3 - 1524
DB4 - 1525
Even If I configure 4 listeners using NETCA, how my failover & load balancing will happen using SCAN & Newly Created Listeners ???
Thanks in advance..
Regards,
Manish

Hi,
I tried on 11gR2 TEST RAC Server to have different listener with different port (1529) for SCAN & Node Listener & tested failover, load-balancing which was successful.

Actually different ports for different databases are required to have separation of duties. Once Firewall enabled betwen Client & DB Server only privileged users would have access to particular database.

How to configure a listener to listen on a different port rather than 1521 and register it on the database

Hi Everyone,
I have used 11gR2 RAC for a couple of years and now I've got this issue because I have tried to setup more than one database on RAC infrasturcture:
I have an existing database on my RAC. (lets call it orcl) which is listening on port 1521 and is functioning properly. Now I want to create anoher database (call it test) which is going to listen on port 1526. I am able to create a listener using netca, (as oracle recommended, I've created it with grid user). I am also able to create a database using dbca (with dba user). My problems stem from when I want to configure listener to register with the new database. If i set local_listener to my newly configured database, it won't be able to tnsping and therefore login. If I create tnsnames.ora file on local or remote server, I am able to ping the database, but when I want to connect using sql*plus (or any other client) I receive TNS-12514 error. By the way, I am using AIX 7.1 as my machine.
Let me know if any more info is required on this topic.

> Now I want to create anoher database (call it test) which is going to listen on port 1526.
Why? What is the purpose of using another listener? An Oracle Listener was designed to service multiple databases running on the same server. In all my years of working with Oracle and running multiple databases on the same machine, I have yet to be required to run more than one listener. And almost every single time I've seen someone try to provide rationale for multiple listeners, the technical reasons have no merit.
> If i set local_listener to my newly configured database
The LOCAL_LISTENER parameter does not point to a database...it points to a LISTENER!
LOCAL_LISTENER=(ADDRESS = (PROTOCOL=TCP)(HOST=hostname)(PORT=1526))
Cheers,
Brian

How to configure CLI/DNIS based access restriction in 5.3 ?

Hi,
does anybody have an idea how the setting
define CLI/DNIS-based access restrictions which is defined in ACS v. 4.2
can be configured in acs 5.3 ?
in v. 4 for every user in a group with 40 members a different CLI is defined for each. How can I configure that in version 5.3 ?
any help as always much appreciated!

The equivalebt to NAR functionality can be found at:
Policy Elements > Session Conditions > Network Conditions > End Station Filters
Can then define an object with a set of CLI values
These objects can then be used in policy conditions. So can create a condition with a set of CLI values and then match in authorization policy for values that are included in this set and set authorizations accoridngly
Not sure if this is your use case but hopefully may be a start

How to configure bpm composer and access the projects present in bpm mds re

To access the bpm composer I performed the below mentioned steps: - Installed the standalone weblogic server with soa server configured
- Invoked the bpm composer using the url : http://machine:soa_port/bpm/composer
- Used weblogic and weblogic1 as username and password.
Please let me know whether I am following the correct approach as I am not able to see any options in bpm composer like open project etc, the project menu appears but there are no projects visible.

The answer couldn't help us much. I will give you the steps we have followed in detail
We have created a sample customizable BPEL process by selecting a Customizable checkbox in Jdev.
Then,The sample BPEL process is deployed to SOA server from JDeveloper. We could see the deployed BPM process in EM console.
Also the MDS repositories required for customization too are present in EM.
Then We tried accessing the BPM Composer to do some customization on the sample BPEL process deployed. We are able to login to the BPM composer using "weblogic" user.
But the composer displays only the welcome page. There are no other links enabled.
Please let us know How to make a BPEL process customizable using BPM composer.
Also there is an another SOA Composer. When this composer is mainly used?
There is another BPM Workspace console. But we could not login to this using "Weblogic" user though we are able to login in EM, SOA and BPM composer.
Why the login failed uisng "weblogic" user here?What for this console is used?

How to configure a user to access RFC functions

In production system, a user account with RFC access privilege is need to configured for a .NET Connector application.
Some documents see than need to add access object RFC_ACL for this user.
But how to operate to add such kind of access object?
Thanks a lot. I'm not very professional on R/3 operation.

Well, for fastest you don't want Fast User Switching enabled, that leaves everything in the other account running, you want to log out of that other account & log into the new one.
Just don't setup Mail or such things in the new account, remove uneeded things from Accounts Login Items.

How to configure one Listener for 2 databases on the same server
