# #########################
# THRESHOLDS:
# #########################
# Send an E-mail for each THRESHOLD if been reached:
# ADJUST the following THRESHOLD VALUES as per your requirements:
HTMLENABLE=Y # Enable HTML Email Format [DB]CPUTHRESHOLD=95 # THRESHOLD FOR CPU %UTILIZATION [OS]
TBSTHRESHOLD=95 # THRESHOLD FOR TABLESPACE %USED [DB]
UNUSEINDXTHRESHOLD=1 # THRESHOLD FOR NUMBER OF UNUSABLE INDEXES [DB]
INVOBJECTTHRESHOLD=1 # THRESHOLD FOR NUMBER OF INVALID OBJECTS [DB]
FAILLOGINTHRESHOLD=1 # THRESHOLD FOR NUMBER OF FAILED LOGINS [DB]

[By Oracle user]
# crontab -e
#Add the following line to schedule the execution of dbdailychk.sh script. let's say every morning:
0 6 * * * /home/oracle/dbdailychk.sh
Note: /home/oracle/dbdailychk.sh is the full path pointing to dbdailychk.sh script.
In case you want to run the script from root user crontab instead of oracle's crontab:
[By root user]
# crontab -e
#Add this line to schedule the execution of dbdailychk.sh script every morning:
0 6 * * * su - oracle -c /home/oracle/dbdailychk.sh
Now, everyday morning you will receive an email summarize the health status of ALL databases running on the that server, also you will receive a separate e-mail if any of defined thresholds been hit.
By default the script will send the report in HTML format if it founds "sendmail" package installed on your system otherwise it will revert to TEXT format, If you don't have "sendmail" installed on your system and you still enthusiastic to receive the E-mail report in HTML format then follow this link:
