How to Upgrade Caché on Linux?

Unfortunately, downloading distributions from WRC is not so easy. For example, you can look at my article Containerization Caché, where I gave an example how to download and install Caché automatically.

Before, we need some variables

product=cache
version=2017.2.0.744.0
arch=lnxrhx64

Download distribution

# WRC Authorization
WRC_USERNAME="user@somecompany.com"
WRC_PASSWORD="password"

wget -qO /dev/null --keep-session-cookies --save-cookies /dev/stdout --post-data="UserName=$WRC_USERNAME&Password=$WRC_PASSWORD" 'https://login.intersystems.com/login/SSO.UI.Login.cls?referrer=https%253A//wrc.intersystems.com/wrc/login.csp' \
 | wget -O - --load-cookies /dev/stdin "https://wrc.intersystems.com/wrc/WRC.StreamServer.cls?FILE=/wrc/distrib/$product-$version-$arch.tar.gz" \
 | tar xvfzC - .

before an upgrade, you should define at least one variable as defined in documentation by your link.

ISC_PACKAGE_INSTANCENAME=$product

for install new instance, you should define more variables

ISC_PACKAGE_INSTALLDIR="/usr/cachesys/"
ISC_PACKAGE_UNICODE="Y"

so, finally, the script will be

#!/bin/bash

product=cache
version=2017.2.0.744.0
arch=lnxrhx64

# WRC Authorization
WRC_USERNAME="user@somecompany.com"
WRC_PASSWORD="password"

wget -qO /dev/null --keep-session-cookies --save-cookies /dev/stdout --post-data="UserName=$WRC_USERNAME&Password=$WRC_PASSWORD" 'https://login.intersystems.com/login/SSO.UI.Login.cls?referrer=https%253A//wrc.intersystems.com/wrc/login.csp' \
 | wget -O - --load-cookies /dev/stdin "https://wrc.intersystems.com/wrc/WRC.StreamServer.cls?FILE=/wrc/distrib/$product-$version-$arch.tar.gz" \
 | tar xvfzC - .


ISC_PACKAGE_INSTANCENAME=$product

/tmp/dsitrib/$product-$version-$arch/cinstall_silent

But it is just a simple example and not covers everything. But can be easily extended by your needs.
