ServiceNow Kill workflows & executing contexts

if there are old inactive tickets in the system with active workflows still executing, this can slow down performance of the system. Root cause should be identified, however this script example highlights how these can be shut down in a controlled fashion from a fix script. it should skip business rules and notifications so that end users are not messaged regarding historic inactive tickets

fix script

var si=new tool_improvement();

si.shutDownActiveWFcontexts_CHG(false);//--true flag means it's not query only and will perform the tidy-up

si.shutDownActiveWFcontexts_REQ(false);//--true flag means it's not query only and will perform the tidy-up

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 )){...
