How to append log instead of creating new log for each run in SAS?

Issue:

My program runs every hour. I need to create one log per day. So I need to append all the log generated by the code to a single file. Next day it should create the log in new file. How to do that?


Solution:

Use the logparm attribute as append. This option will append the log on the same file.

-logparm "open=append"

The batch code will be:

/opt/sas/config/Lev1/SASApp/BatchServer/sasbatch.sh -sysin "myprogram.sas" -log "myprogram_`date +"%Y-%m-%d"`.log" -logparm "open=append" -print -noterminal

You can see I have used date command to make it daily. You can change the occurence using that command.

For more details about Logparam follow the below link:

Insufficient authorization to access PIPE error in SAS EG

Issue: When I tried to run SAS code in SAS Enterprise Guide it throws following errors: ERROR: Insufficient authorization to access PIPE. ERROR: Error in the FILENAME statement. Screenshot of error: Solution: This error occurs when you try to run OS commands in SAS code. To run the OS commands in SAS code you need to enable XCMD option. You check it in SAS Management Console by following below steps.   Open SMC -> Expand Servers -> Expand   In SASApp , expand Logical Workspace Server -> right click on Workspace Server. Click properties -> option tab -> advanced options -> launch properties. Check whether Allow XCMD is checked. The issue arises if the Allow XCMD is not checked. In above image, Allow XCMD option is not checked. It should be checked to run OS commands from SAS code. In Unix /Linux machines, this XCMD option can be enabled by using system option XCMD in sasv9 config file or workspaceserver.sh script f...

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.
