Security Software

Hi,

I am implementing SSO of EBS R12 using OAM, I follow the posts on Metalink(376811.1). But there is a problem when I do the Registration of OID for EBSR12 using these scripts:
"$FND_TOP/bin/txkrun.pl \
-script=SetSSOReg \
-registerinstance=yes"
I am quite sure that the parameters are right, but I got the exception bellow:

-----
[appl05@ebs004 bin]$ txkrun.pl -script=SetSSOReg -registerinstance=yes

You are registering ORACLE HOME only.

Enter the host name where Oracle iAS Infrastructure database is installed ? 192.168.11.19
Enter the LDAP Port on Oracle Internet Directory server ? 3060
Enter SSL LDAP Port on Oracle Internet Directory server ? 3131
Enter the Oracle Internet Directory Administrator (orcladmin) Bind password ?
Enter Oracle E-Business apps database user password ?
