Assuming all services are defined using the format in the example above the code below will try to execute the script checkinstance.sql connecting to every service using sqlplus (assuming it can be found in the path):
Code:
perl -ne'
  /^(\w+)\s*=\s*$/ and 
    $stmt .= "conn username/pass\@$1\n\@checkinstance.sql\n";
  if (eof) {
    ($cmd = <<_END_) =~ s/^\s+//gm;
      sqlplus /nolog<<_SQL_
        $stmt
      _SQL_
_END_
    qx/$cmd/;
       }' tnsnames.ora

If you really only want to generate the statements:

Code:
perl -lne'
  /^(\w+)\s*=\s*$/ and 
    print "conn username/pass\@$1\n\@checkinstance.sql\ndisc"
  ' tnsnames.ora

OK,
if you prefer shell scripting, you may try something like this:

Code:
while read svc; do
  svc="$(
    expr "$svc" : '^\([a-zA-Z_]*\) *= *$' 2>/dev/null
    )" && 
    printf 'conn user/pass@%s\n@checkinstance.sql\ndisc\n' "$svc"
done<tnsnames.ora
