What are the process that run when SPDS server is started in SAS?

Issue:

How to check SPDS process is up or not.

Solution:

After you start SPDS server following process should be running.

spdsnsrv - Name server component
Central starting point for SPD server

spdssnet - SPD SNet server component
Interface between clients other than SAS clients and the name server

spdsbase - SPD user proxy
Process started by the data server for each user access or query.

spdsserv - Data server component
Validates the user credentials and starts a SPDSBASE user proxy

spdslog - Logging process
Writes the server name server, and snet server logs and recycles the logs at specified times.

Note: data server and proxy process should always run on the same machine because proxy process is started by data server process. Other process can run in different machine.
