SAP WebDispatcher Not routng ABAP requests

[Former Member]

Hi Everyone,

When I test the webdispatcher I can connect to J2ee systems without a problem but not to any of the abap urls.

On the j2ee side I test it with

http://sapsp1ci20:8022/index.html

On th abap side I test it with

http://sapsp1ci20:8022/sap/public/ping?sap-client=200

I get a response that the service is not available although it is activated in SICF. I also get this for the standard webgui and anyotehr url I would expect to work.

1. I have installed the sap webdispatcher (relno 7000, patchlevel 0, patchno 229) for NW 7.00 on with a J2EE patch 17.

2. I have configured the ms/http_port to 8021 in the ABAP profile and set the is/HTTP/default_root_hdl = abap.

3. The following ICM services are active icr_groups, icr_urlprefix, logon_groups, urlprefix

4. The sapwebdisp.pfl was generated using the -bootsstrap option an is as follows:

1. Profile generated by sapwebdisp bootstrap

2. unique instance number

SAPSYSTEM = 22

1. add default directory settings

DIR_EXECUTABLE = /usr/sap/SP1/webdisp

DIR_INSTANCE = /usr/sap/SP1/webdisp

1. Accessibility of Message Servers

rdisp/mshost = sapsp1ci20

ms/http_port = 8021

1. SAP Web Dispatcher Parameter

wdisp/auto_refresh = 120

wdisp/max_servers = 100

wdisp/shm_attach_mode = 6

1. configuration for large scenario

icm/max_conn = 16384

icm/max_sockets = 16384

icm/req_queue_len = 6000

icm/min_threads = 100

icm/max_threads = 250

mpi/total_size_MB = 500

mpi/max_pipes = 21000

#maximum number of concurrent connections to one server

wdisp/HTTP/max_pooled_con = 2000

wdisp/HTTPS/max_pooled_con = 2000

1. SAP Web Dispatcher Ports

icm/server_port_0 = PROT=HTTP,PORT=8022

icm/server_port_1 =

1. SAP Web Dispatcher Web Administration

icm/HTTP/admin_0 = PREFIX=/sap/wdisp/admin,DOCROOT=./admin,AUTHFILE=icmauth.txt

Has anyone else experienced this issue before.

I have read OSS notes: 1101010, 1068501, 1048692, 1068501 and does not appear to be relevant for my patch level.

I had removed teh parameter ms/http_port = 8021 from my DEFAULT profile and all worked. thanks for all the responses.

Hi Michael,

What is the product you are using ?

For an ABAP+JAVA instance you should have two profiles. i.e one is the central instance profile and other is the SCS instance profile.

There is a parameter ms/server_port_0 = PROT=HTTP,PORT=81$$ in the profile.

SCS instance stands for Java and DEVEBMGS profile will point to ABAP.

Check the DVEBMGS instance number. If its 00 then your ms/http_port on the web dispatcher should point 8100.

Check the above parameter and revert.

Hi Michael,

I hope your abap message service port is not 8021. It is 8020.

Change the ms/http_port in the web dispatcher profile to 8020 and then give a try.

Hi Raghu,

thank you very much for the response.

I updated the ms/http_port in the abap and the sapwebdisp.pfl and I still get the same error.

Should I be updating the table twpurlsvr with the information as well?

Which logfiles can I use on the ABAP side to trace the error? Or should I just increase th sapgwe trace level and keep an eye on that?

kind regards
