83                                 From Dan Scott on [
84                                   open-ils-general/2007-July/000316.html|OPEN-ILS-GENERAL]:
85                                 On 8/11/07, lan ye &lt;lye at> wrote:
86                                 > We've been researching the Evergreen Open Source Library system,
87                                 > and would like to have a list of hardware requirements for the
88                                 > installation of a small test server. To keep things within a
89                                 > small budget, I would like to just use an ordinary PC. Could you
90                                 > send some information to us?
92                                 For system requirements, it depends on how extensive you want your
93                                 tests to be. Evergreen and all of the pieces it depends on
94                                 (PostgreSQL, Apache, Ejabberd) run happily in a VMWare image
95                                 allocated 512MB of RAM on my laptop with just the Project
96                                 Gutenberg e-books loaded, and that's enough to evaluate the OPAC
97                                 interface / try out the staff client / make some local changes and
98                                 generally experiment. But I'm not going to load one million bib
99                                 records into that system and expect it to perform. So, probably
100                                 any hardware you have lying around would be adequate for a small
101                                 test server.
103                                 > It looks like Evergreen has been successfully installed on two
104                                 > Linux systems: Gentoo and Ubuntu. Which one is the best for us
105                                 > to test using what's already in place at other libraries? Are
106                                 > there any differences / Advantages in functionality between
107                                 > Gentoo and Ubuntu?
109                                 As John said, GPLS is running on Debian, and that's the only
110                                 Evergreen system that is in production at the moment. However, the
111                                 documentation for installing on Debian is a bit scattered right
112                                 now. The developers themselves used Gentoo originally, and that's
113                                 what I'm using at the moment &amp; have documented in the wiki;
114                                 the install process on Ubuntu is very thoroughly documented and
115                                 Ubuntu is reasonably close to Debian.  
116                                 See 
117                                 for the list of install instructions for various distributions.
119                                 As for advantages / disadvantages of particular distributions,
120                                 that's a religious war that I don't want to step into... We'll try
121                                 to help you out no matter what distribution you choose; just
122                                 please choose a current release :)

130                                   pipermail/open-ils-general/2007-July/000317.html|thread]:
131                                 We are running a test Ubuntu server on a ~1ghz Celeron PC with
132                                 512mb RAM.  It seems to be ok handling the Gutenberg samples, and
133                                 our collection of about 8000 records. We did have serious problems
134                                 using anything less than 512mb RAM. Also, I tried Evergreen on a
135                                 K6 II 350, but it wasn't pretty.

145                         <para>This sections describes examples of some working Evergreen system architectures, including both server-side software and Staff Client software.</para>
146                         <para>A bare-minimum system requires only a single Evergreen Server and a single Evergreen Staff Client, both residing on a single server machine. In fact, that is a reasonable architecture for simple experiments or as a proof of concept in a conference-room pilot. But typical real-world systems will probably consist of at least one or two Evergreen Servers plus multiple Staff Clients.</para>
147                         <para>Another simple system may require only that you install one or more instances of the Staff Client software. For instance, if your consortium already provides the Evergreen server software or if you are using the hosted version provided by Equinox, you do not need to install the Evergreen server-side software at all; you need only the Staff Client.</para>
