I am running adadmin/adpatch on one ebs 12.1.3 instance. But I am getting below error when I enter 'SYSTEM' password.
AD Administration needs the password for your 'SYSTEM' ORACLE schema
in order to determine your installation configuration.
Enter the password for your 'SYSTEM' ORACLE schema:
...Unable to connect.
AD Administration error:
The following ORACLE error:
ORA-12545: Connect failed because target host or object does not exist
occurred while executing the SQL statement:
Unable to connect to 'SYSTEM'; password may be invalid.
1)I am able to connect SYSTEM user through sql
SQL> conn system/manager
2) I am able to ping this machine
Could anyone please help me to resolve this error?
