How to configure simultanous access for 11i application

Question

Hi All
We have one existing 11i application instance on node grid1.In which we start the servicess from apps user.
In our same we want another node for the same application in which we will start the servicess from another user(merge)
For that we perfrom the following steps
1.Copy the APPL_TOP,COMMON_TOP,ORA_TOP(8.0.6,iAS) from node "GRID1" to diffrent node "GRID2"
2 configure the GRID2 node using adcfgclone.pl utility(we have configure new node for WEB and FORM Server)
3 We perfrom the modification in the following files ON GRID2 .
i Identify 'FNDNAM=apps' statement in $FND_TOP/secure/<context>.dbc
and replace with 'FNDNAME=merge' to connect to MERGE schema instaed of APPS.
ii. Go to the last line of $APACHE_TOP/jserv/etc/zone.properties file
and identify 'schema=APPS' statement and change it to 'schema=MERGE'
iii. Identify below lines in $APACHE_TOP/modplsql/cfg/wdbsvr.app file
password = apps
     username = apps
     document_table = APPS.fnd_lobs_document
and replace with modified below lines
password = merge
     username = merge
     document_table = MERGE.fnd_lobs_document
6. For redirecting user's request to new Application Server server, we
changed the following 4 system profile options with proper URL and port
at responsibility level only for the responsibilities,
which we use for Merge views.
Profile Options
     Application Framework Agent
     Applications JSP Agent
     Applications Web Agent
     Apps Servlet Agent
When we are able to start the services on GRID2 node,but at the time of login we are getting invalid user name/ passwd error
Please let us know is there any way to access application other than apps user

well thank you very much .I know how to define a DataSource inside Weblogic Server.
But i am confused over one issue
When We are going to use Container Managed EntityManager inside the SessionBean the persistence.xml file looks like this
*<persistence>*
*     <persistence-unit name="RamsEJBPU" transaction-type="JTA">*
*          <jta-data-source>myJtaDataSource</jta-data-source>*
*     </persistence-unit>*
*</persistence>*
But in some cases it looks like as shown below :     <persistence-unit name="RamsEJBPU" transaction-type="resource-local">
     <provider>org.hibernate.ejb.HibernatePersistence</provider>
                    <properties>
               <property name = "hibernate.connection.driver_class" value = "oracle.jdbc.driver.OracleDriver"/>
               <property name = "hibernate.connection.url" value = "jdbc:oracle:thin:@localhost:1521:orcl"/>
               <property name = "hibernate.connection.username" value = "CHENNAISPAT"/>
               <property name = "hibernate.connection.password" value = "CHENNAISPAT"/>
            </properties>
     </persistence-unit>
</persistence>Can you please tell me why is it so ??
