parallel instances on windows

[Cory Zue <cz...@dimagi.com>]

Hey foks,

I'd like to migrate my application from 1.0.2 to 1.1, but
unfortunately I'm using a windows dev environment.

Is there any way to run parallel installations of couch on different
ports on windows?

thanks,
Cory

You can only have one running as a service, but yup its easy.

There are 3 ways;

#1 by replication
Install 1.1 to c:\some_other_folder_of_your_choice.
don't add it as a service when prompted.
open up local.ini in some editor & change the port & IP to whatever you need.
open a command prompt & cd to c:\some_other_folder_of_your_choice.
set erl=erl
bin\couchdb.bat

Run futon or use curl to set up your replication per DB.
when complete, trigger each view.

stop 1.0.2 couch, change local.ini back to 5984 etc & anything else
your app needs.
if a service is required use erlsv.exe to set it up [1].

#2 by restore
Do all of the above installation points.
Instead of replicating just restore your 1.0.2 .couch files
when complete, trigger compaction for each DB.
when complete, trigger each view to be rebuilt.

stop 1.0.2 couch, change local.ini back to 5984 etc & anything else
your app needs.
if a service is required use erlsv.exe to set it up [1].

#3 by in-place upgrade.
do backup
uninstall 1.0.2
confirm you've only got var/lib/couch var/log/couch etc/couch remaining.
install 1.1.0
when complete, trigger compaction for each DB.
when complete, trigger each view to be rebuilt.
