, here are two types of job-specific monitoring and alarm monitoring.
Job Custom Statement Monitoring
1. Create a job, the core is to add the specified data in the step when monitoring over the trigger notification. A raiseerror can be used here:
2. Configure notifications when the failure is sent by email.
2. Alert monitoring [code] What is an alert: MS SQL Server automatically records what happens in the Windows program log. The SQL Server Agent automatically monitors the program execu
a function for a naming attribute of the prototype attribute. the name assigned to the function is the name of the method called on the object.In the following example, we define and use the sayHello () method for the Person class.
The Code is as follows:
Function Person (gender ){This. gender = gender;Alert ('person instantiated ');}Person. prototype. sayHello = function (){Alert ('hello ');};Var person1 = new Person ('male ');Var person2 = new Person ('female'); // call the sayHello method o
note: Creates a callback that passes Arguments[0], arguments[1], arguments[2], ... Call directly on any function. Example:myFunction.createCallback (Arg1, arg2) would create a function that's bound to those 2 args. If a specific scope is required by thecallback, usecreatedelegate INstead.
