sapwebdisp configuration


Hi ,

Our sapwebdisp file configuration is

# configuration for default scenario (medium size)
icm/max_conn      = 500
icm/max_sockets   = 1024
icm/req_queue_len = 500
icm/min_threads   = 10
icm/max_threads   = 50
mpi/total_size_MB = 80

#maximum number of concurrent connections to one server
wdisp/HTTP/max_pooled_con = 500
wdisp/HTTPS/max_pooled_con = 500

# SAP Web Dispatcher Ports
icm/server_port_0 = PROT=HTTP,PORT=80,TIMEOUT=30,PROCTIMEOUT=1200
icm/server_port_1 =

Due to some reasons we wanted to change this configuration. we wanted to increase the following parameters as below

icm/max_conn      = 1000

icm/max_threads   = 100

wdisp/HTTP/max_pooled_con = 1000

icm/server_port_0 = PROT=HTTP,PORT=80,TIMEOUT=120,PROCTIMEOUT=1200

Will there be any negative effect on that server or on other servers?

Are there any limits to increase for those parameters?

Please let me know.

Regards,

Guru.

    Guru,

    These parameters affect the total amount of resources consumed by the application server so you will need to verify that the hardware available (steady state and peak) can handle the additional traffic on the server.  This scaling is very hardware specific and also tied closely to what each user session is actually trying to do (some are small tasks and others have larger implications).

    Based on the above comments you are not talking about a huge jump in resources but do you really have 1000 concurrent HTTP requests coming into the server at peak volumes and if so what does your availble CPU %, Available RAM, and Disk Utilization look like when this is happening?
