Instructions:
1 - Copy COpt_3.10_Prerequisite_Check.tgz file to planned COpt 3.10 Server.
2 - Extract tgz file into a temporary directory (Ex. /tmp/scripts).
    Ex. tar -xvf COpt_3.10_Prerequisite_Check.tgz -C /tmp/scripts
3 - Run the "COpt_Prerequisite_Check.sh" script to check the system.
4 - Output is recorded into the COpt_Prerequisite_Check_<Date_Time>.log file in the current directory.
 
  "Usage:  COpt_3.10_Prerequisite_Check.sh [-sz <Deployment Size>] [-tz <Time Zone>] [-ts <Time Server>] [-change] [-enable]"

   "-sz <COpt Deployment Size> = Size of COpt Server Deployment (Optional, Ex. small, medium or large, default is small)."
   "-tz <Time Zone> = Set System Time Zone and synchronize time if necessary (Optional, requires using -change option.)"
   "-ts <Time Server> = Time Server to be used with Time Configuration (Optional, requires using -change option.)"
    "-change = Change the prerequisite settings to required settings for installation (Optional, Default is to Not Change settings)."
    "-enable = Enable the Firewall after configuring required ports (Optional, requiries using -change option.  Default is to Disable Firewall.)"
 
A log file of output is generated within the COpt_3.10_Prequisite_Check_<date/time>.log file in the current directory.
 
Examples of Usage:
To perform a check only:
# /tmp/scripts/COpt_3.10_Prequisite_Check.sh
 
To perform a check only for a non-small environment:
# /tmp/scripts/COpt_3.10_Prequisite_Check.sh -sz large
 
All additional options require using the -change option.
# /tmp/scripts/COpt_3.10_Prequisite_Check.sh -sz small -tz America/Los_Angeles -ts ntp.company.com -change -enable
 
How do I obtain support for the COpt_3.10_Prerequisite_Check.sh script?
The prerequisite check script is a contributed toolkit and does not have an official support.
Nevertheless we are interested to know about potential problems and suggestions.
For now, feedback can be addressed to mark.a.butler@microfocus.com .
Questions will be addressed on best effort basis.
