Hi adarsh,
Thanks for your quick reply.

We have done that steps.

We want write custom dyn_resource script. for example,
******** in schedule config file **********
all_lic !/usr/local/bin/check_license.sh
free_lic !/usr/local/bin/free_lic.sh

server_dyn_res:“all_lic free_lic”

that both variables should assign to one dyn_resource.
is it possible ?

that scripts output:
[root@sjrvlsiserver2 pbs]# ./license_check.sh
XT_XPLORER_SE
XT_XCC_TIE
XT_ISS_BASE
XTENSA_SDK
[root@sjrvlsiserver2 pbs]# ./free_lic.sh
2

2
2
[root@sjrvlsiserver2 pbs]#

Hi Ramesh,

each of the variable should be one server_dyn_res resource.

Hence you need to you have one per
XT_XPLORER_SE
XT_XCC_TIE
XT_ISS_BASE
XTENSA_SDK

XT_XPLORER_SE !/usr/local/bin/check_license_XT_XPLORER_SE.sh
XT_XCC_TIE !/usr/local/bin/check_license_XT_XCC_TIE.sh
XT_ISS_BASE /usr/local/bin/check_license_XT_ISS_BASE.sh
XTENSA_SDK /usr/local/bin/check_license_XTENSA_SDK .sh

or you can have a script and pass these varialbe as arguments to that script
server_dyn_res: “feature1 !/path/to/script [args]”

for example:
[root@sjrvlsiserver2 pbs]# ./free_lic.sh
2

and not

[root@sjrvlsiserver2 pbs]# ./free_lic.sh
2
2
2
2

Please note , any server dyn resource output should be just an integer and not a string and should have multiple new line characters

Please check this guide and below section

Hope this helps.

Hi Adarsh
How are you ?

can you please guide me how to set the [args] in schdule configure file ?

FYI: you can have a script and pass these varialbe as arguments to that script
server_dyn_res: “feature1 !/path/to/script [args]”

For example: this is the license check script /usr/local/bin/license.sh

#!/bin/bash
feature=$1
case $feature in
    mech)#here you have your query statement that prints out the available (int) licenses
		#for this feature 
        echo "1"
        ;;
    cfd)#here you have your query statement that prints out the available (int) licenses
		#for this feature 
        echo "2."
        ;;
    opti)#here you have your query statement that prints out the available (int) licenses
		#for this feature 
        echo "2"
        ;;
esac

Add the below line to the $PBS_HOME/sched_priv/sched_config

server_dyn_res: “mech !/usr/local/bin/license.sh mech”
server_dyn_res: “cfd !/usr/local/bin/license.sh cfd”
server_dyn_res: “opti !/usr/local/bin/license.sh opti”

kill -HUP after making these changes to the sched_config

Hope this helps, also you can refer the below section from this guide https://help.altair.com/2024.1.0/PBS%20Professional/PBS2024.1.pdf
