logon load balance in abap

[Former Member]

Hi ,

we are facing a challenge in our landscape in bogon load balancing between different application servers. we have configured log on groups.

we have a performance testing team which uses load running to input virtual users and test how the load is equally distributed across all the servers.

in their testing they have found, the users are not equally distributed between all the servers.

my question is how can we determine the load distribution works fine or control the message server which does the work?!

anybody has come across this issue before?

appreciate your immediate appropriate response.

thanks.

also note 26317 can come in handy

Also  there is a rdisp/autoabaptime parameter which decides how frequent the job should run.the program that performs this activity is RSRZLLG0_ACTUAL which runs as a background job and populates RSRZLLICLASS table.Also check when the last data about the load was taken from SMLG->loadbalancing

How many logons are you trying per minute .The SMLG reads the loads of the system every 5 minutes only via a background job which populates a table.So if the performance test is too fast it might not work as the load balancing is not realtime.

Hi Siva,

The way it works is that an algorithm is used to calculate the server "Quality" that you can see on SMLG, the users get assigned to the server with best quality at the time of logon.

So, not always is even specially if the application servers on the logon group has different specifications.
