How to use the script?
==================

Step 1: Download the script from this link:
-------
https://www.dropbox.com/s/w1dpw3iynphm07t/dbdailychk.sh?dl=0

Step 2: Customize the script to your environment:
-------
Change the E-mail address to your email address in line number 80
MAIL_LIST="youremail@yourcompany.com"

Note: sendmail service should be well configured on the target machine in order to send emails from.

Customize the defined thresholds under THRESHOLDS section, as per your preferences:
Modify the numbers in red color:

# #########################
# THRESHOLDS:
# #########################
# Send an E-mail for each THRESHOLD if been reached:
# ADJUST the following THRESHOLD VALUES as per your requirements:

FSTHRESHOLD=95    # THRESHOLD FOR FILESYSTEM %USED [OS]
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]
AUDITRECOTHRESHOLD=1     # THRESHOLD FOR NUMBER OF AUDIT RECORDS       [DB]
CORUPTBLKTHRESHOLD=1    # THRESHOLD FOR NUMBER OF CORRUPTED BLOCKS[DB]
FAILDJOBSTHRESHOLD=1      # THRESHOLD FOR NUMBER OF FAILED JOBS   [DB]

Step 3: Schedule the script to run in the crontab: [Recommended to run once a day during non-peak hours]
--------
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 run 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 same server, also you will receive a separate e-mail if any of defined thresholds been hit.
