I am looking for scripts to monitor Data Guard?
Can someone help me with this please?
Thanks in advance.

These scripts are Unix specific:
## THIS ONE IS CALLED BY THE NEXT
#!/bin/ksh
# last_log_applied.ksh <oracle_sid> [connect string]
if [ $# -lt 1 ]
then
     echo "$0: <oracle_sid> [connect string]"
