Upgrading From Single Server to Distributed Architecture
Last Updated: 3/13/2009
For Products:
Webtrends Analytics 7.5x
Webtrends Analytics 8.0x
Webtrends Analytics 8.1x
Webtrends Analytics 8.5x
Situation:
Your analysis environment has grown, and you need to take your single Webtrends machine and add additional machines to handle more reporting, or additional features, and you want to upgrade to a distributed architecture.
Solution:
Upgrading from a single machine to a distributed architecture, first thing's first, make your backups.
Edit the analysis queue and cancel all currently running scheduled tasks.
Stop all services (Scheduler first, Database last)
Backup your entire \Webtrends\storage folder and sub-folders
What database are you using
MySQL? MSSQL?
MySQL is simply backing up the 2 following folders.
\Webtrends\common\database\mysql\data\wtmaster \Webtrends\common\database\mysql\data\wt_sched folders
To back up an MSSQL DB, see the MS documentation.
Then you need to set up permissions for your Webtrends services account (KB article 052070); and then share the storage folder to the network, so that the Webtrends services account can access it and make sure all the proper Security & Permissions are in place (KB Article 072596).
After this is taken care of, restart the server, (still standalone) starting with the database, Then change the storage locations to point to the shares, rather than the absolute paths that they are.
For example:
C:\Program Files\Webtrends\storage\config
Becomes:
\\ServerNameGoesHere\storage\reports
As soon as you click 'save' it will prompt to continue until all jobs have finished, or to cancel all tasks, even if none are in the queue. I usually recommend this option, as it will take care of the unseen system jobs. Log out and let the services shutdown and reboot. This may take some time. If the paths are the same, the system will simply be doing a copy/verify. If Webtrends looks and sees the new directory has nothing in it, or if you're creating a new data location, it will copy the data to that location at this time.
After that, you're up and running, in a distributed architecture, of one computer.
When you install on the 2nd machine, do not install the system DB, just the components you wish to use. Analysis Engine, GeoTrends, additional UI Servers, etc.
