https://docs.servicenow.com/bundle/paris-platform-administration/page/administer/security/reference/session-activity-timeout.html

after you have installed the plugin Limit Concurrent Sessions plugin (com.glide.limit.concurrent.sessions)

these properties need to be set to true: glide.authenticate.limit.concurrent.interactive.sessions

and to the glide.ui.session_timeout value desired (default is 60 mins)

you may wish to run the following fix script and code this business rule also to default the setting:

BUSINESS RULE: default limit_concurrent_sessions to true when creating a new user (exclude integration users if you wish) - before insert and set condition to 'u_service_account=false' or similar

(function executeRule(current, previous /*null when async*/) { //-- see STRY0010717 current.limit_concurrent_sessions=true; })(current, previous);

FIX SCRIPT: bulk update existing users

var grUsers = new GlideRecord('sys_user'); grUsers.addQuery('u_service_account', 'false'); grUsers.addQuery('limit_concurrent_sessions', 'false'); //grUsers.query(); //gs.print(grUsers.getRowCount()); grUsers.setValue('limit_concurrent_sessions', 'true'); grUsers.updateMultiple();

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 )){

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 ); }
