Those Damn NRPCs

Since Notes is a client server solution it generates a significant amount of NRPC calls between the Notes client and the Domino server. Thousands of NRPCs are created during simple actions like searches and lookups. If you are developing Notes client applications that are used only inside your LAN you will never notice this because the NRPCs are quickly processed. However, if you are accessing the Domino server through the Web, the time to process the NRPCs grows exponentially as packet jumps from router to router. What took less then a second on your LAN could take minutes or longer. One way to reduce the delay cause by NRPCs is to process as much of your transactions using RunOnServer agents.

For our applications, we package everything as XML and process the XML using RunOnServer agents and return the response as XML which is then process on the Notes client using string manipulation which is very fast. From the response XML, we then populate the form. Therefore, there is separation between the data and form. In theory this should keep the NRPCs to a minimum.

I was on-site at our customers working with them to modify a project management tool that we developed. Since most of the users do not reside in the office where the server is located we spend a significant amount of time creating RunOnServer agents to handle the majority of the transactions. We also spent a significant amount of time on the UI to make the experience pleasant for the user. However, even with all this effort the NRPCs continue to bite us and each transaction is slower then it should be. The problem that I have discovered is that the field population process itself like:

doc.fieldName = "hello"

generates NRPCs though everything should be processing on the Notes client. This was very frustrating.

It is that time of year in Chicago

Spring in Chicago can be a challenge. One minute it is 70 degrees and sunny and the next it can be rain 39 degrees and windy or snowing. So far this year the spring weather has been up and down, up and down. On Saturday it was nice and warm at 70 degress in the morning when I left to go to my office. When I came out it was thundering, raining with a 40 mph wind gush and it was 39 degrees. Thought I have live here most of the life (except when I was working Washington DC for 4 months), I was naive enough to think it would stay warm and had only a T-shirt on. This definitely does not help me recover from by sinus infection that I have had over the past couple of days.
