5.5.3 Supported Link Components
The support of link components in virtual environment is limited to all KCS modules. Modules of third-party
vendors may work as well, but Kofax does not guarantee their functioning.
The major performance indication of a link server is the message throughput including document
conversion.
Therefore, tests were performed that focused on throughput to show the dependencies based on various
environment scenarios (physical machine Mod. 300, VMw are ESX server, …).
Common parameters for performance measurements of TC/LINK-FI document conversion
1) Used operating system of link server(s) was Windows 2003 SP1 + all patches (available by March
2007) installed
2) Office 2003 Professional SP2 all patches (available by March 2007) installed
3) Used link package TC/LP 2.20.00., newer version of TCDCKey.DLL (2.09.01 )
4) All trace levels (general, TCDC, …) have been set to 0
5) TraceLevel on TCOSS server set to 0x1083, TraceFlags set to 0x40
6) Minimum duration of all TCDC conversion throughput measurements was 1 hour
7) Minimum duration of all Lincoln, TCIMG32 and Datalogic Library conversion measurements was 20
minutes
8) PDF conversion done with Acrobat Standard 7.0.8 (using script)
9) Alternatively PDF conversion done with Acrobat Reader 7.0.7 (no script)
Used servers
1. Physical machine Mod. 300
KCS Mod. 300 – TA11 main board, 512 MB RAM, 1 x 2,8 GHz Xeon processor, SCA hard disk
2. VMware session under ESX server - version 3.0.1 – Build 32039
VMware session 512 MB RAM, 1 x 2,8 GHz Xeon processor
3. VMware session under (GSX) server - version 1.0.2 39867
Single VM instance, installed on Win 2003 server with 3 GB physical RAM,
512 MB used for the VMware session
4. VMware session under VMware Workstation 5.5
Single VM instance, installed on Win XP with 2 GB physical RAM, SCA hard disk
512 MB used for the VMware session
Tested functions
Document conversion was tested with a single instance TC/LINK-FI polling a local API directory (to avoid
side effects), connected to a single TCOSS server via 100 MBit public LAN. The single TCOSS server is a
Mod. 301 with a 28 lines PRI (permanently sending / receiving via all channels). The PRI LS1 is connected
via a crossover network cable to the TCOSS server.
