Detta avser program version 5.4  

Systemkrav

HansaWorld Enterprise kräver minst 50 Mb av ledig plats på hårddisken vid installation, men mer plats kommer att krävas eftersom databasen växer vid regelbunden användning. Programmet passar för användning på blandade klientmiljöer(t ex. nätverk med Linux, Mac OS X och Windows klienter), förutsatt att alla maskiner har TCP/IP installerat.

HansaWorld Enterprise kräver inte att Windows eller Mac OS X fildelning är på.

Vilken anställd som helst kan arbeta med HansaWorld Enterprise i ett lokal nätverk eller via wide area network. Eftersom HansaWorld Enterprise stödjer brandväggar oberoende på vilken typ av internetuppkoppling du (ADSL, ISDN eller modem), rekommenderar vi att en mjukvara för brandväggar installeras på servermaskinen.

Angående säkerhet, det är viktigt att nämna att dataflödet mellan HansaWorld Enterprise server och klienterna är krypterat. Back-up filer som skapas använder möjligheterna som är inbyggt i HansaWorld Enterprise även de är krypterade. Varje användare kommer att få ett unikt användarnamn och lösenord för att logga in, och du kan använda inställningen Lösenordsskydd i modulen System för att tvinga användarna att byta lösenord frekvent.

Serverhårdvara

Följande hårvarurekommendation gäller för alla platformar:

  • The server should be dedicated (i.e. you should not use it for any other purpose such as print spooling or running separate applications).

  • The server should have a fixed line connection and a static IP address.

  • Server hard disks must have disk protection (RAID 1, 5, 1+0 etc). Unprotected disks, such as single disks and disks in RAID 0 configuration, will put your vital data at considerable risk.

  • There should be an off-site back-up capability, the simplest version of which is a directly connected tape drive, with back-up software, well-established routines and testing. The routines should include moving the current tape to a different location every night (in case of fire or other disaster), and periodically testing that you can use the latest back-up file to restore the database successfully.
Described below are three sample configurations that have been shown to give acceptable performance of HansaWorld Enterprise in normal usage. If your usage is expected to be very heavy or very light, please make adjustments as appropriate. If you have other functions running, such as an integrated web shop, then make provision for extra capacity.
The users are assumed to be normal users in a typical system using the Sales, Purchase and Nominal Ledgers, Logistics and CRM. If you are deploying a system with a significantly different usage pattern, your needs could be larger or smaller. For example, HansaWorld Business Communicator users are lighter users than normal users, while a high volume Point-of-Sale user creating large Invoices that update stock would need more resources than a normal user.

Small Server - passar för 1 - 5 användare

  • CPU 1.8 GHz, one core

  • RAM 1 Gb

  • Disk 2 x 7200 RPM mirrored disks

  • Internal network speed (network card, switches etc) 100 Mb/s
Medium Server - passar för 3 - 30 användare
  • CPU 2.0 GHz, two cores

  • RAM 2 Gb

  • Disk 4 x 10000 RPM

  • Hardware RAID controller with 128 Mb write cache backed by battery

  • Internal network speed (network card, switches etc) 100 Mb/s
Large Server - passar för 20 - 60 användare
  • CPU 2.5 GHz, four cores

  • RAM 4 Gb

  • Disk 6 x 15000 RPM

  • Hardware RAID controller with 256 Mb write cache backed by battery

  • Internal network speed (network card, switches etc) 1Gb/s (to allow for backing up over the network)
The recommended CPUs are the current generation (2007) Intel and AMD x86 CPUs. You can also use IBM POWER4 and later based systems with similar GHz ratings. Old Intel Pentium 4 (NetBurst-based) machines should have higher GHz ratings.

For larger configurations please contact your HansaWorld office for help with configuring the appropriate hardware for your situation

Operativsystem

HansaWorld Enterprise server kan du använda på följande operativsystem

  • Mac OS X och Mac OS X Server 10.3.9 och senare (universal)

  • Windows 2000 och senare

  • RedHat Enterprise version 3 och senare, SuSE Enterprise och Ubuntu/Kubuntu är rekommenderade Linux distributions because of the level of OS support that is available. On graphical clients, KDE is the recommended desktop environment as it includes the necessary fonts as standard

  • IBM AIX

  • IBM i5/OS (in PASE mode)

  • Sun Solaris (SPARC)
Du bör tänka på följande när du väljer vilken miljö du kommer använda HansaWorld Enterprise:
  • För Windows Vista, behöver du ytterligare minne.

  • Om du kör på Microsoft Windows, rekommenderar vi att du har en mjukvara för hantering av anti-virus.

  • På alla platformar, rekommenderar vi att ha en mjukvara för att hantera back-uper.

  • When installing in a virtual environment (VMware, Xen etc.), take special care to ensure disk-writing consistency. HansaWorld Enterprise normally ensures the consistency of its database by forcing data to the physical disk device, or battery backed cache if available. In some configurations with virtualisation software these safety features can fail to be enabled. You must ensure that this disk synchronisation is enabled inside the virtual environment.
Nätverk

HansaWorld communicates using TCP/IP networking, and has relatively low bandwidth requirements. However, for a good user experience we do recommend a low latency.

A network connection of 30 kb/s for the first user and an additional 10 kb/s per user tends to give an acceptable working environment. The recommended bandwidth is 50 kb/s for the first user and an additional 15 kb/s per user. This is the bandwidth that should be dedicated to HansaWorld. This bandwidth figure should be increased if users will also be using the network for other purposes such as web-browsing, if they will routinely produce large reports with many pages of output, and/or there will be frequent use of the Attachments feature to attach files to records or mails. If the users are idle, the bandwidth usage decreases.

Network latency should preferably be at or below 0.1 seconds. Latencies up to 0.5 seconds can generally be worked with; however, the user experience will start to suffer at this level or above.

As an example, a 128 kb/s line into the server (e.g. dual ISDN connection) with a 0.1s latency will give good performance for up to 6 users and will be useable for 10-11 users, providing they do not also often use the connection for other tasks such as transferring files.

For internal use HansaWorld routinely tests a GPRS connection (0.5s latency, 20-50 kb/s bandwidth) for 2-4 users using CRM and e-mail functionality, while this "feels a bit sluggish" it is a fully workable system.
