Here are some tools you should be familiar with if you are a SAS Admin.

Tools monitor CPU:

First thing to check when your SAS programs performs poor is CPU.Following tools can be used.

glance (multi-purpose)
sar (multi-purpose)
ps
xload

Memory:

SAS uses WORK as temporary storage, however PDV and input buffer created in memory. It has to be free for your program to perform fast.

Tools:
glance (multi-purpose)
sar (multi-purpose)
size
vmstat
ipcs

Disk:

Disk involves WORK, home directory and SAS intallation and configuration directory. There should be enough space in all the directory where SAS lookup.

Tools
glance (multi-purpose)
sar (multi-purpose)
bdf
df
iostat

Network:

It is the last component we check when we have some issues in SAS Application. Remember, SAS is client-server model and network plays an important role. Many SAS components depends on network resouce. SAS metadata and OLAP server demands robust network for qucik response rate. SAN storages are mostly shared using NFS and it requires good network connectivity.

Tools:

The authentication server is not SETUID ROOT error in SAS

Question: When validating the SAS Server from SAS Management Console, I received the following error: The authentication server is not SETUID ROOT.  So, I ran the setuid.sh utility and restarted the services many times. I just checked the elssrv sasauth sasperm setuid bit. There were no error in sasauth-debug.log, sasauth-access.log, sasauth-error.log.  Any suggestions? Answer: Please do the following:    1) Run /<SASConfig>/Lev<X>/ObjectSpawner/ObjectSpawner.sh stop  2) Edit /<SASConfig>/Lev<X>/ObjectSpawner/ObjectSpawner.sh and add the code shown below right after SCRIPT=`basename $0`:  if [ -n ""$TKPATH"" ]; then  unset TKPATH  fi   if [ -n ""$TK_PATHLIST"" ]; then  unset TK_PATHLIST  fi    3) Run /<SASConfig>/Lev<X>/ObjectSpawner/ObjectSpawner.sh start  The above code change in ObjectSpawner.sh should fix the issue.
