Delete the connection and credential aliases that do not label any connection or
credential record by running a background script. This helps you in freeing up space in your
system.

## Before you begin

Role required: System Admin (admin)

## Procedure

1. Navigate to AllSystem DefinitionsScripts - Background.
2. Select the scope as global.
3. Enter the following script in the Run script (JavaScript executed on server) pane.  

       deleteOrphanAliases();
       function deleteOrphanAliases() {
           var orphanAliases = new GlideRecord('sys_alias');
           orphanAliases.addEncodedQuery("nameSTARTSWITHDevOps-_-");
           orphanAliases.query();
           while(orphanAliases.next()) {
               if (!checkIfAliasHasConnection(orphanAliases.getUniqueValue()))
                   orphanAliases.deleteRecord();
           }
       };
       function checkIfAliasHasConnection(sysAliasId) {
           var httpToolConnGR = new GlideRecord("http_connection");
           httpToolConnGR.addEncodedQuery("connection_alias=" + sysAliasId);
           httpToolConnGR.query();
           if (httpToolConnGR.next())
               return true;
           return false;
       };
