How to use the script?
==================
Step 1: Download the script from this link:
-------
https://www.dropbox.com/s/k6dt3zeow4ztbcl/dbdailychk.sh?dl=0
Step 2: Customize the script to your environment:
-------
Change the E-mail address to your email address in line number 56
MAIL_LIST="youremail@yourcompany.com"
Note: sendmail service should be up and running and well configured on the target machine.
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=98 # THRESHOLD FOR FILESYSTEM %USED [OS]
CPUTHRESHOLD=95 # THRESHOLD FOR CPU %UTILIZATION [OS]
TBSTHRESHOLD=98 # 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:
--------
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's 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
From now on, you will get an email, if any of the defined thresholds reached for ALL DATABASES ON THE SERVER.
