max Real-Time Services per Access Server

dataservices realtime
#1

Hi,

does anybody know how many Real-Time Services we should have max per access server?

Currently we have 108 Real-Time Services Running on one Access Server (all published as WebServices too) and we’re seeing that in the past days some of the older ones are running instailbe and aborting / restarting often.
This they did not do the past 3 years.

In general i can say that we have around 10 Real-Time Services with are having a high frequency of incoming request and around 20-30 Real-Time Services with complex operations.
The rest are “standard”…just reading 1-2 tables and responding the values or so…

Could this be an Access Server Problem? Or Tomcat?
If it’s an Acces Server issue, will it solve the problem to just enable a second access server on the same machine and split the jobs to 60 jobs on AccessServer1 and 60 Job on AccessServer2 ?

Thanks in advance for your help

We’re on DS 4.1

Start up a new access server, move some of your high frequency work over and compare the average response times before and after.

Less service instances, more access servers … double your throughput.

now if we could only pre-cache the process so they dont take so long to recycle…

start will real time service log (RT Job log), possibly the job is failing often and restarting
also, check the Access Server logs to see If the service is restarting due to reaching the recycle count
