Working with Linux MID Servers

some useful UNIX commands

e.g. via Putty

downloading the agent folder for a manual MID server upgrade:
use curl url

MID Server Stop/Start/Status commands

stop the MID server:
using command
sudo /usr/bin/systemctl stop mid

start the MID server:
using command
sudo /usr/bin/systemctl start mid

status of MID:
/usr/bin/systemctl status mid

rename the agent folder to old_agent using:
mv agent old_agent_nov2019

delete operations
delete folder and contents:
rm -rf <folder_name>
delete file:
rm <file_name>

restore backup files
navigate to the folder
run commands to restore backup files:
cp config.xml /app/midserver/agent/
cp wrapper-override.conf /app/midserver/agent/conf/
cp agent_keystore.jks /app/midserver/agent/keystore/
cp cacerts /app/midserver/agent/jre/lib/security/

list directory contents
use 
ll

exit back to prompt
ctrl c

view a file contents read only
vi /app/midserver/agent/conf/wrapper-override.conf
then  :q to exit without saving

pull down a log file
2019-08-05 08:34:49 PROD root@<user>:~> $ find / -name *glide-dist-upgrade.log* 2>>/dev/null 

search for something
ps -ef | grep -i "upgrade"

check port 443
netstat -ano | grep 443

display current directory
pwd

create a directory, e.g. 'keystore' in agent folder

mkdir keystore

grant permissions on a folder
You can use command : chmod 777

Get URL Parameter - server side script (portal or classic UI)

Classic UI : var sURL_editparam = gs . action . getGlideURI (). getMap (). get ( ' sysparm_aparameter ' ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); } Portal : var sURL_editparam = $sp . getParameter ( " sysparm_aparameter " ); if ( sURL_editparam == 'true' ) { gs . addInfoMessage ( 'parameter passed ); }

ServiceNow check for null or nil or empty (or not)

Haven't tested these all recently within global/local scopes, so feel free to have a play! option 1 use an encoded query embedded in the GlideRecord , e.g.  var grProf = new GlideRecord ( 'x_cls_clear_skye_i_profile' ); grProf . addQuery ( 'status=1^ owner=NULL ' ); grProf . query (); even better use the glideRecord  addNotNullQuery or addNullQuery option 2 JSUtil.nil / notNil (this might be the most powerful. See this link ) example: if ( current . operation () == 'insert' && JSUtil . notNil ( current . parent ) && ! current . work_effort . nil ())  option 3 there might be times when you need to get inside the GlideRecord and perform the check there, for example if the code goes down 2 optional routes depending on null / not null can use gs.nil : var grAppr = new GlideRecord ( 'sysapproval_approver' ); var grUser = new GlideRecord ( 'sys_user' ); if ( grUser . get ( 'sys_id' , current . approver )){
