4:03 a.m.
I have a class
Employee
(name)
Certificates
(course, year, employee)
If the employees have CCNA & CCNP from the “same” year and then if they took
“CCIE or J5SE in 2000” or “J4WS in 2001 or 2002, or 2003”
The Action should be taken if there are more than 5 such employees.
The connection between Employee and Certificates is through
Certificates.employee, but I can change it to a list of certificates in
Employee also if needed.
I start with
$e: Employee()
Certificate (employee == $e, course == “CCNA”, $ccnaYear : year)
Certificate (employee == $e, course == “CCNP”, $ccnpYear : year)
//this will get the years for one employee..
//now we need to get all other employees from same year..
//but we still need to make sure all certificates are from the same
employee.
ArrayList( size >= 2 ) from collect(Certificate (
((course == “CCNA”, year == $ccnaYear, $e_this:employee) && (course ==
“CCNP”, year == $ccnpYear, employee == $e_this))
&&
(
((course == “CCIE”, year == 2000, employee == $e_this) || (course == J5SE”,
year == 2000, employee == $e_this))
||
((course == “J4WS”, year == 2001, employee == $e_this) || (course == “J4WS”,
year == 2002, employee == $e_this) || (course == “J4WS”, year == 2003,
employee == $e_this))
)
)
This is going crazy at this stage.
First problem, - I start with one employee, and try to get his years of CCNA
and CCNP
Next I am collecting Certificates instead of Employees which I should be
collecting and checking the length of the employees.
I think something like this will help me
http://blog.athico.com/2007/06/chained-from-accumulate-collect.html
But I am unable to convert it into my usecase.
Please help.
Thanks

Due to imprecise wording, this may or may not be what you want. The rule fires,
if there are 5 or more Employees, each of them with the property that
- the employee has visited CCNA in year X
- the employee has visited CCNP in year X
- the employee has visited CCIE or J5SE in 2000 OR
has visited J4WS in 2001 or 2002 or 2003 (OR both)
(There is no relation between the years X of different employees.)
rule findCombi
when
accumulate(
Certificate( course == "CCNA", $e: employee, $y: year )
and
Certificate( course == "CCNP", employee == $e, year == $y )
and
Certificate( employee == $e,
((course == "CCIE" || == "J5SE" ) && year ==
2000 )
||
course == "J4WS" && year == 2001 || == 2002 || == 2003
);
$es: collectSet( $e ); $es.size() >= 5 )
then
System.out.println( "more than 5" );
end

Actually it is a event from an application usecaseThanks for your reply and I
think I am very close with your help.This rule is giving error Line 99:5
mismatched input 'or' in rule "usecase-test"]rule
"usecase-test" when
$e0 : Event () ParsedValue(event == $e0, ruleId == "0", varName ==

) ); $es: collectSet( $e ); $es.size() >= 5 ) then
System.out.println( "usecase-test" + $es.size());endThe Event comes from
application and is parsed for values.The event from same application will
have the same values for ruleId=0, varName-V0_1 and V0_2So any event with
same values for V0_1 and V0_2 is coming from same application.The rule says
if from same applicationyou have values which has this combinationruleId ==

"X3_3"In pure english it isFirst I have to identify if I am dealing with
events from same applicationThis is by comparing (2) parsed values V0_1 and
V0_2. If they are same across events .. then it having same source.Next lets
check for other conditions..From Rule 1.. I want to check values of V1_1 and
V1_2, if there is a issueFrom Rule 2.. I want to check values of V2_1 and
V2_2, if there is a issueNow I do not want to raise exception as soon as
condition is met.. since the problem can occur and can be ignored. But if it
happens more than 5 times from the same source, then I want to raise an
alert.

I tried a simpler version
rule "usecase2-test2"
when
$e0 : Event ()
ParsedValue(event == $e0, ruleId == "0", varName == "V0_1",
$e0_V0_1_varStringValue : varStringValue)
ParsedValue(event == $e0, ruleId == "0", varName == "V0_2",
$e0_V0_2_varStringValue : varStringValue)
accumulate(
ParsedValue( ruleId == "0", varName == "V0_1", varStringValue ==
$e0_V0_1_varStringValue, $e:event )
and
ParsedValue( event == $e, ruleId == "0", varName == "V0_2",
varStringValue == $e0_V0_2_varStringValue )
and
ParsedValue( event == $e, ruleId == "1", varName == "V1_1",
varStringValue == "X1_1")
and
ParsedValue( event == $e, ruleId == "1", varName == "V1_2",
varStringValue == "X1_2");
$es: collectSet( $e );
$es.size() >= 2 )
then
System.out.println( "usecase2" + $es.size());
end
but when I insert 2 events with same source (meaning same values with
(ruleId == "0", varName == "V0_1") and (ruleId == "0",
varName == "V0_2")
and right values for rule1 variables
then also it works with one single event and never satisfies this condition.

It's not possible to use the conditional element "or" inside an
accumulate. (Reading up on the "or" CE should give you an idea why.)
And that's why I
used a boolean expression as a constraint within the third pattern.
