A lot of questions for the Jade gurus out there
a) On windows NT server there is an option on Network NeighbourHood/Properties/Services/Server/Properties which allows you to select the memory usage
of the server. Reading the Help file suggests that "Maximize throughput for network applications" option should be selected as it is intended for applications
that setup and maintain their own cache memory i.e. SQL server. Is this also applicable to Jade?
b) Our production servers each have 160 MB. Before starting the Jade server there is approx. 130 MB available.While watching the performance monitor during
a trading day, the amount of available memory drops to approx.
30 MB. Is this memory taken up by the Jade server caching etc. ? The problem arises when
we run end of day methods which uses up the remainder of the available 30 MB (building begin/commit transaction logs ?) which results in excessive disk
paging. Is the only answer more memory?
c) The other day I logged out all the active Jade users and tried to shut down the Jade server, which informed me that there were still
active users. Ran the Jade
monitor which showed approx. 8 nodes/users still present. I have a suspicion that when an unhandled exception occurs on a workstation the users are resorting
to Alt-F4 to remove the active forms and restarting the application, or just Ctrl-Alt-Del and restarting. Are these nodes in the Monitor remnants of their crimes
and what are the implications with regards to performance especially when some of these nodes still seem to have files locked ?
d) During the course of a trading day a warehouse workstation will only display the Invoice entry screen for hours without any problems. However when the
user tries to use another part of the application the
workstation will lock up for no apparent reason. Running task manager to remove the process I find the End
Task button is greyed out, suggesting that the Jade process is non-existent. How can the program run for hours with no process?
e) Last but not least, to solve an internal dispute - all our Jade applications run over a legacy token-ring network. Would a Jade application perform faster over
a switched 10/100 ethernet network.
Any answers greatly appreciated
