multiple application servers on development system

[former_member186444]

Hi,

forgive my ignorance as I am a developer, so not from a Basis background. Our Basis staff have recently switched from 1 to 2 application servers on our development system. This has meant that there is up to a 2 minute delay in updates occurring due to the synch that needs to take place between the 2 servers. Of course, this hampers the development effort as it means that each time a change is made we need to wait up to 2 minutes to see the impact of the change.

Our Basis staff have told me that 2 minutes is the SAP-recommended synch time as any less could impact upon the whole performance of the development system.

The change has been made in order that each system is the same throughout the landscape (dev, qa, Prod).

Can anyone offer any thoughts on this issue? For example, is it usual practice to have multiple application servers on a development system and if so, is there a way around the delay that happens until the synch takes place?

thanks,

Malcolm.

What actions/changes you do that require up to 2 mins to sync?

[former_member186444]

thanks for your replies so far guys.

Roman - for myself I am working with Web Dynpro ABAP, making changes to UI elements currently. I can make a change and it not be reflected on execution for a couple of minutes after activation. Other developers are noticing the same thing with abap code as well though.

In a well configure scenario no delay should exist between instances.

I'll ask basis for a detailed explanation of why are those delays happening.

As I understood after one developer changed ABAP code from one application server these changes are not visible on another application server until the interval of 2 minutes has elapsed. Am I right?

[former_member186444]

I just checked and that is not the case - the changes are visible on the other application server. The issue is with the runtime object. The changes are not see in the object when it is executed at runtime until maybe 2 minutes have passed.

Under the changes I had in mind runtime execution of modified program. If yes try to use $SYNC command to flush buffers on another application server and check results.

Hi.

Try to turn off cache on your MIME objects, that must help to resolve your issue.

Hi Malcom,

Firstly there is no need to have application servers on development server. Never seen in any landscape so far.

The delay defined is not SAP standard, the issue could be with the database resources. I feel there are no sufficient resources in the system and hence resulting into delays.

Hi ,

There should not be any delay if all the application serevr has enough resource .

Because there will be  central enqueue for lock management which is responsible for sysn or update.

best regards,
