Getting error in SAS MID Tier Services script

Question:
We are getting below error while executing the SAS Mid tier services script while starting.

Starting SAS Web App Server: SASServer11_1
(this can take a while)
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 30 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected
waiting 60 ...
/sas/config/mid/Lev1/sas.servers.mid: line 192: [: users: integer expression expected

We open the script using VIM editor and checked in the line 192 ,there is only a if then statement which an we believe it is a valid one.   

 ROLLCHK=`ls -l $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`
# clear leading blanks, then strip trailing filename
ROLLCHK=`echo $ROLLCHK | tr -s ' ' | cut -d ' ' -f 5`
if [ $ROLLCHK -lt $ROLLMARK ];
then
{
echo "Note: $SASWEBAPPINSTANCE server.log rolled over during startup."
MYMARK=1
}
fi

Though the services status is showing as UP but we are not able to open any Mid Tier application.

Answer:
Modify lines 152 and 188 of sas.servers.mid to use "ls -n" instead of "ls -l" when querying the server.log file to get around this problem:
 
From
ROLLMARK=`ls -l $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`
ROLLCHK=`ls -l $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`

To
ROLLMARK=`ls -n $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`
ROLLCHK=`ls -n $SASWEBAPPSRV_DIR/$SASWEBAPPINSTANCE/logs/server.log`

It looks like either user or group names contain spaces.

SAS 9.4 server startup order

In Linux / Unix OS we normally use sas.servers to start the services. The script in the background follows an order to start the services. It is important to follow the order to run the services correctly. In this post we can see what is the order to start / stop and to generate the sas.servers script. It is not really required to memorize the order because SAS provide an utility to create the sas.servers script automatically which will start / stop the service in order. Starting order SAS Metadata server Olap server SAS object spawner SAS / SHARE server SAS / connect spawner SAP table server SAP remote services SAS deployment tester server Stopping will be the same in reverse. How to create sas.server script? We can create sas.server script by using generate_boot_script.sh. if you have made any changes to your environment like adding a new server or spawner we can use the script to generate new sas.server. You can use the script even if you have removed the spanner o...

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.
