Refreshing SPD Server Parameter and LIBNAME
Files
The REFRESH Command
You can use PROC SPDO to dynamically refresh SPD Server parameter and LIBNAME
files. If you make changes to your spdsserv.parm file or to your libnames.parm environment
file for SPD Server, you can use the REFRESH command to avoid restarting the server.
Submitting the REFRESH command refreshes the specified SPD Server file without
restarting the server.
When you submit the REFRESH command, SPD Server refreshes the operating parameter
file.
The syntax for the REFRESH command to refresh the libnames.parm file is:
REFRESH DOMAINS
The syntax for the REFRESH command to refresh the spdsserv.parm file is:
REFRESH PARMS
Each REFRESH operation completely refreshes and replaces the contents of the previous
libnames.parm file or the spdsserv.parm file in the SPD Server environment.
REFRESH Command Examples
Add a new LIBNAME domain to your current libnames.parm file and use it without
restarting the server:
LIBNAME spds44 sasspds 'spds44'
server=estore.5180
user='admin'
