How to remove a J2ee instance from logon load balancing

[Former Member]

Hello,

We have a abap+java dual stack installation including 4 j2ee instances in a cluster.

Users who want to logon to the portal for example use url: http://<virtual host name>:8171/irj (71 is the SCS instance number). This url imidietally translates to http://real host name:5XX00/irj (XX is the system number of one of the four instances). This is done in a round robin fashion.

My question is how do I proceed If I want to remove one of the java instances from the load balancing, without stoping the instance of course. Something analogous to removing an abap instance from SMLG.

Thanks

To do load balancing, mean you have configured WebDispatcher rignt?

please check webdispatcher configuration file and it will have entry for all the clustered servers, please remove unwanted entries from the webdispatcher config file (ex: sapwebdisp.pfl) and restart the service.

Hi,

The address you are giving is http://ip:81xx/irj,

but the portal always uses this sort of address format http://ip:5xx00/irj/portal

The 80xx port is the abap port,where as the 5xx00 is the http port and your portal uses only this port to commute.To remove this from user acess just block the port 5xx00 for your instance,

or else tell them to use the 5xx00 port and mention your other instance which you want to use.
