How do I run an SQLPlus script to perform several Administration functions?

Here is the syntax

sqlplus /nolog <uid>/<pwd>@<instance> @<scriptpath>

Create two files, one named admina.sql with the following:

Revoke execute on UTL_FILE from Public;
Revoke execute on UTL_TCP from Public;
Alter user CTXSYS identified by Test12 account lock password expire;

and one named adminb.sql with:

Revoke execute on UTL_FILE from Public;
Revoke execute on UTL_TCP from Public;
Alter user CTXSYS identified by Test12 account lock password expire;

And then to execute from the SQL prompt type:

@admina or @adminb

You have to ensure that files are in your current directory as you load sqlplus otherwise you have to supply the full path name for example if the files are store in C:\scripts

SQL> @C:\scripts\admina

You don't have to put the .sql suffix on the end of the filename when executing, it will work both ways.

I think missymadi is asking to execute from Batch File

Extending AJ's contribution:
#!/usr/bin/sh
sqlplus /nolog <uid>/<pwd>@<instanceA> <<EOF
Revoke execute on UTL_FILE from Public
/
Revoke execute on UTL_TCP from Public
/
Alter user CTXSYS identified by Test12 account lock password expire
/
EOF

And repeat as needed.  You might want to create a new question and learn how to pass the SID name as an argument to the batch file.
