Webdispatcher for Load balancing

838 Views

Hi All,

We have implemented EP7. The portal is configured to redirect to https.

Now we want to use sapwebdispatcher for load balancing.

We are performing the following steps to configure the sapwebdispatcher

1. uncar the icmadmin.SAR

2. sapwebdisp -bootstrap

The following screen appears:

This bootstrap will perform the following steps:

1. create profile file "sapwebdisp.pfl"for SAP Web Dispatcher (if not already existing)

2. create user for web based administration in file "icmauth.txt"(if not already exisiting)

3. start SAP Web Dispatcher with the created profile

After the bootstrap you can use the web based administration

Generating Profile "sapwebdisp.pfl"

Hostname of Message Server (rdisp/mshost): <hostname>

HTTP Port of Message Server (ms/http_port): 8101

Checking connection to message server...OK

Unique Instance Number for SAP Web Dispatcher (SAPSYSTEM): 38

HTTP port number for SAP Web Dispatcher: 8101

Create configuration for s(mall), m(edium), l(arge) system (default: medium): l

WARNING: Maximum number of sockets supported on this system: 2045

Please check the operating system configuration

Profile "sapwebdisp.pfl" generated

Authentication file "icmauth.txt" generated

Web Administration user is "icmadm" with password "xxxxxxxxx"

Restart sapwebdisp with profile: sapwebdisp.pfl

sapwebdisp started with new pid 14014

Web administration accessible with "http://<hostname>:8101/sap/wdisp/admin/default.html"

SAP Web Dispatcher bootstrap ended (rc=0)

<hostname>47> *** WARNING: Could not start service 8101 for protocol HTTP on host "<hostname>m"(on all adapters)

  • SAP Web Dispatcher up and operational (pid: 14014) ***

Now, if I use any port other than 8101 for HTTP port number for SAP Web Dispatcher the webdispatcher does not work.

If i use port 8101(which i am using currently) then the webdispatcher does the load balancing however i cannot access the http://<hostname>:8101/sap/wdisp/admin/default.html url

Can anyone help me getting both thigs: load balancing and the webdisp admin page also.

Thanks!!

Regards,

Rohit
