Command Summary

Installing VistA

Install Cache

This phase of the installation creates an area (a namespace) for you to work in and point that namespace to the distributed VistA database.

<tbody>

1.	Install Caché (The free single user version of Caché from <a href="http://www.intersystems.com">www.intersystems.com</a>). These are the instructions for the Windows version. Accept all of the defaults.
2.	Create the directory c:\CacheSys\Mgr\Vista and unzip CACHE.zip into it. The Cache.zip file we used was dated 4/5/2003 and was 137 Mb (141,243,089 bytes). The unzipped CACHE.DAT was also dated 4/5/2003 and was 430 Mb (451,379,200 bytes).
4.	Right Click on the Caché Cube and choose Documentation. Make sure it opens up and you can search it. If it doesn't, it is likely a firewall is blocking your access to CacheWeb. As of 5/03, McAfee firewall will need to be uninstalled entirely and other firewalls may need to be disabled. <a href="mailto:support@intersys.com">support@instersys.com</a> can help you if you need it. If all goes well opening the documentation, then continue.
5.	Right Click on the Caché Cube again and choose Configuration Manager.
6.	Choose Databases tab then click Add. A database is a physical disk location where M programs and data are located.



7.	Type "VISTA" in the Database window then click Next>.



8.	Pick location C:\Cachesys\Mgr\Vista then click Next.



9.	Answer Yes to the question do you wish to use CACHE.DAT and then click Finish.





10.	Choose the Namespaces tab then click Add. (Cache documentation defines a Namespace as "A logical entity or workspace that is associated with a directory, and that provides the link between a set of globals and their actual locations.")



11.	Type in "VISTA" in the Namespace window then click Next.



12.	From the list of Currently defined databases - Choose VISTA.
