How to Upgrade Caché on Linux?

#DevOps #System Administration #Caché

Hi, Community!

Say you have a standalone Caché server on Linux (E.g. Ubuntu) (no mirroring) and you have sudo access via ssh.

What is the easiest, safest and simplest way to upgrade Caché to the new release? 

How do you do this?

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.
