Datasocket event trigger

Hi,
I am using datasockets to comunicate between PCs/VIs.
One VI has an event structure, which is in a 10ms timed loop. I have followed one example on this forum, which uses the timeout event to trigger the appropriate event with a property node (Value Signal) - but this causes events when I donot want them to occur.
I have also put a datasocket read in the 10ms loop to write to the Value Signal property node, which slows things down a lot and skips triggers/signals, which entirely defeats the purpose of events in the first place.
Are there any (better) ways around this?
Thanks,
Michael
BTW I'm using Labview 7.1.1

You have an event structure with a 10ms timeout, and within your timeout you perform a property value (signal) write !? This will generate 100 events a second! No wonder you get events when you don't want them.
Sometime posting your code helps us to understand what it is you're struggling with.

Sales order creation, standard event trigger is taking long time .

We have a requirement where we are sending data to CRM system using RFC function module. This data is sent while sales order creation or change. We have used standard event BUS2032.CREATED to trigger CRM FM in sales order creation mode. In sales order change mode, we are using custom event. In production system, our custom change event is getting triggered fine and data is sent to CRM system with small time lag of around 1 minute. But, while sales order creation, standard event trigger is taking long time ( sometimes about 20 minutes) in production system.
We tried triggering same custom event at the time of sales order creation using FM u2018SWE_EVENT_CREATE_IN_UPD_TASKu2019 as well but, still we are not able to improve performance of the event trigger at sales order creation.

HI,
we have written SWE_EVENT_CREATE in update task
I think instead of calling in update task simply call to function module CALL FUNCTION "SWE_EVENT_CREATE" might trigger the event immediately.. Did you try to check in this way..
OR
And I also suggest you to check the entry in SWE2 txn with respect to your workflow tempalte, may be you have enable the option ENABLE EVENT QUEUE, this could be one of the reasons.. If it is enabled please disable it (uncheck)
Please check..

BI Publisher event trigger and email notification

How can I event-trigger a BI publisher report, i.e., start the BI publisher report after completion of a ETL job?
In addition, after generation of the BI publisher report, how can I send to destinated email addresses?
Thanks

Write custom java code , which uses the BIP web-services and put a trigger on the ETLJOB.
Re: Run BI Publisher from the command line through a shell script
Re: Run BI Publisher from the command line through a shell script
BIP has provided a webservice,
One of the function is to run or schedule a report.
Write a simple Java program, which will look at the server and point to run the report you wanted.

How to create schedule job and event trigger in XI to start a ABAP program?

Dear All:
Here are what i need to do:
1.To run a ABAP program to start an XI scenario per hour.
2.To run a ABAP program to start an XI scenario per day at 6 PM.
3.To run a ABAP program used event trigger to make sure that XI scenario has finished the process and after that wait for 10 min later and run again.
only i know is used sm36 & sm37 to set up a schedule job.
but what i don't know is how to do it step by step.
especially point 3.
are there any step by step example can show me how?
it better be simple and details...
thanks you all
Regards
Jack Lee

Hi,
If you want to trigger the event manually from within SAP, use transaction
SM64
in SAP this is done by scheduling a job
once a new customer is entered
your scheduled report sends customer master data
you can schedule your report (TCODE - BD12 I think) to one day or every 5 minutes... it depend on your needs and the system performence

Event trigger in sap pi 7.3.1

Hi
I looking standard approach on below requirement .
1. Requirement : All failed messages needs to post to JMS adapter using Event trigger , when message failed in SAP PI.
2.Audit log : In SAP 7.3.1 I need to post message audit log to JMS adapter using Event trigger (Start time / End time ) without using BPMs.
Please suggest on this.
Thank you
Inder

Hi Inder - Regarding the audit log - have a look at the below blog
http://scn.sap.com/community/pi-and-soa-middleware/blog/2013/03/09/michals-popi-tips-audit-logs-from-a-native-ws--new-feature (1)
For the alerting , either you can use above suggested approach or have a look at the below blog
Customize E-Mail Body and Subject in Alerts in SAP PI 7.31 – Java Stack Only – Part 1 – ESR (2)
May be you can merge both of them, after reading the alerts(2) make another soap call to get the audit log entries(1) and send it to JMS adapter..
Of course it's not an event based instead it works based on polling Interval that you configure in the channel..

'Inserting' text into a Text Field on event trigger in a static form

Sorry if this seems like a silly question, but I've been struggling with it for a bit and I'm new to Adobe/JavaScript.
I am building a static form (it must be static), and I want to have text appear/disapear based on an event trigger (mouseclick). I tried creating a floating text object inside of a static text object, but I'm not sure how I can make the string value for this change based on the event trigger. The only advice in the Adobe help was purely regarding FormCalc, which I can't use as this must be a static form. I tried using this code in the <script>, but it obviously didn't work as it was written from FormCalc code versus JaveScript;
TextField.rawvalue = variable.value;
What do you suggest in terms of being able to script this, so my static form will work? Thanks a billion if you can help!
PS: I'm using Adobe 9, LiveCycle ES 8.2
PPS: Also tried inserting the following into my trigger script;
xfa.resolveNode("form1.subform.TestField").rawValue= "Please Work";
xfa.layout.relayout("form1.subform.TestField");
It also did not work.

Hi,
If the button and the textfield are on in the same subform then this code should work in the click event of the button
(This is JavaScript code so make sure the code is set to JavaScript and Client on the drop downs in the script window)
(assuming the name of the textfield is TextField1)
TextField1.rawValue = "some value";
If they are in different subforms then you have 2 options
Please note in both these options it is easier if the subforms have names ( I am assuming this to keep samples simple)
option 1 -
use the parent object to move up the tree till you are at the same level as that of the subform that contains the textfield
e.g.
(Click Event of the button)
this.parent.subformname.TextField1.rawValue = "some value";
option 2 -
Use the resolve node to make your way down from the top level of the form
xfa.resolveNode ("form1.subformname.TextField1").rawValue = "some value";
Hope this helps
Malcolm
p.s. I am making assumptions as the image/file you attached did not appear for me.

Event Trigger BI Publisher 11g

I have an event trigger defined as type After Data. The function executes.. inserts into a table (table used to verify if function is actually executing via BI Publisher).
The problem I'm seeing is that the parameter in the report that globally goes out is sent but the parameters that are globably coming back are not populated in the report.
This package works fine in BI Publisher release 10.1.3.4.
In the properties of the Data Model I have included package for Oracle DB Default Package
The parameter are defined as:
1. Name: REQNUM, Data Type: String Default Value: Parameter Type: Text
2. Name: PMAXUSER, Data Type: String Default Value: Parameter Type: Text
3. Name: PMAXDATE, Data Type: String Default Value: Parameter Type: Text
4. Name: MYTESt, Data Type: String Default Value: Parameter Type: Text
In options I have Refresh other parameters on change checked.
Thank you in advance for your help.

First, make sure you've got enough machine resources as BIEE11g is resources hungry.
Next, after installation you should have icons to start BIEE11g (try windows version as it is easier to start up).
Run the startBIEE11g script and it will take some minutes, be patient. Once you get all processes running
then you can try to login.
Take a look at my post:

ALTER USER를 실행한 사용자를 확인하는 방법(SYSTEM EVENT TRIGGER)

제품 : ORACLE SERVER
작성날짜 : 2002-11-07
ALTER USER를 실행한 사용자를 확인하는 방법(SYSTEM EVENT TRIGGER)
================================================================
PURPOSE
자신이나 또는 다른 user들의 password를 바꾸는 등의 alter user command를
사용한 사용자를 확인하는 방법을 알아보자.
Explanation & Example
1. 사용자 정보를 저장할 event table을 생성한다.
Create event table and users to store the alterations made:
SQL> connect / as sysdba;
create table event_table
ora_sysevent varchar2(20),
ora_login_user varchar2(30),
ora_instance_num number,
ora_database_name varchar2(50),
ora_dict_obj_name varchar2(30),
ora_dict_obj_type varchar2(20),
ora_dict_obj_owner varchar2(30),
timestamp date
create user test1 identified by test1;
grant create session, alter user to test1;
create user test2 identified by test2;
grant create session to test2;
2. SYS user에서 AFTER ALTER Client Event Trigger 를 생성한다.
Note: This step creates a trigger and it is fired whenever the user "test1"
issues ALTER command (It can be ALTER USER or ALTER TABLE)
SQL> CREATE or REPLACE TRIGGER after_alter AFTER ALTER on database
BEGIN
IF (ora_dict_obj_type='USER') THEN
insert into event_table
values (ora_sysevent,
ora_login_user,
ora_instance_num,
ora_database_name,
ora_dict_obj_name,
ora_dict_obj_type,
ora_dict_obj_owner,
sysdate);
END IF;
END;
3. test1 user로 접속한 후 test2 user의 password를 변경하는 작업을 실행한다.
SQL> connect test1/test1
SQL> alter user test2 identified by foo;
4. test2 user의 password가 test1 user에 의해 변경되면 그런 내용을
event_table 에서 확인할 수 있다.
Now that we have altered the "test2" user password from user "test1", the
event_table should have captured this details.
Now Login in as sys and Query on event_table:
SQL> connect / as sysdba;
SQL> select * from event_table;
ORA_SYSEVENT ORA_LOGIN_USER ORA_INSTANCE_NUM
ORA_DATABASE_NAME
ORA_DICT_OBJ_NAME ORA_DICT_OBJ_TYPE
ORA_DICT_OBJ_OWNER TIMESTAMP
ALTER TEST1 1
T901.IDC.ORACLE.COM
TEST2 USER
13-JUN-02
event_table의 내용을 조회하여 LOGIN_USER와 ALTERED USER 는
ORA_LOGIN_USER와 ORA_DICT_OBJ_NAME column을 통해 확인할 수 있다.
비슷한 방법으로 아래의 event에서 trigger를 생성하여 확인할 수 있다.
1) BEFORE DROP
2) AFTER DROP
3) BEFORE ANALYZE
4) AFTER ANALYZE
5) BEFORE DDL
6) AFTER DDL
7) BEFORE TRUNCATE
8) AFTER TRUNCATE

Event structure: have one event trigger another event

I have an event structure with two events. I want the finalization of the first event to trigger the second event. Both events are triggered by a boolean value change, say "boolean 1" and "boolean 2". Can I have a local variable of boolean 2 inside event 1. By changing its value, it should trigger event 2. However, this doesn't seem to be working. (see attached example)
any help?
Solved!

test.vi ‏9 KB

Tim's reply is the answer you are looking for.
I would like suggest that you create a sub-VI that doesw the work in the second event you want to fire so tht rather than resorting to having one event trigger another, you can simply use the sub-VI that does the work in event_2 after the sub-VI that does the work for event_1.
If you decide to stick one event triggering another, please clearly document the sceme in BOTH events. What you want to avoid is latter deciding event_1 should be triggered by Event_2 and the next thing you know, your app hangs.

특정 USER에서 DDL 등의 COMMAND 실행을 제한하는 방법 - DDL EVENT TRIGGER

제품 : ORACLE SERVER
작성날짜 :
특정 USER에서 DDL 등의 COMMAND 실행을 제한하는 방법 - DDL EVENT TRIGGER
=======================================================================
Purpose
User에 있는 table등에 DDL 문장이 실행되지 않도록 막고 싶은 경우가 있다.
Oracle8.1.6 부터 사용가능한 system trigger에 의해 이런 기능을 구현해 보자.
Explanation
Oracle8.1.6 의 new feature인 DDL event trigger를 이용하여 특정 user에서
특정 DDL(예를 들어 create, drop, truncate 등)이나 모든 DDL이 실행할 때
에러를 발생시킨다거나 특정한 action을 하도록 설정할 수 있다.
DML 의 경우는 기존의 trigger 대로 각 object에 대해 각각 생성하여야 한다.
이 자료에서는 주로 DDL 이나 DML 이 실행될 때 에러를 발생하도록 하여 해당
문장이 실행되지 않도록 하는 방법을 기술하였다.
(system or ddl event trigger에 대한 다른 자료로 Bulletin 11903,11848 참고)
DDL event trigger 를 이용하기 위해서는 $ORACLE_HOME/dbs/initSID.ora
file에서 COMPATIBLE parameter의 값이 "8.1.6" 이상으로 설정되어 있어야 한다.
DDL event trigger 는 각 DDL이 발생할 때에 실행되는 trigger로
다음과 같은 시점에서 실행되도록 만들 수 있다.
BEFORE ALTER, AFTER ALTER, BEFORE DROP, AFTER DROP,
BEFORE ANALYZE, AFTER ANALYZE, BEFORE ASSOCIATE STATISTICS,
AFTER ASSOCIATE STATISTICS, BEFORE AUDIT, AFTER AUDIT,
BEFORE NOAUDIT, AFTER NOAUDIT, BEFORE COMMENT, AFTER COMMENT,
BEFORE CREATE, AFTER CREATE, BEFORE DDL, AFTER DDL,
BEFORE DISASSOCIATE STATISTICS, AFTER DISASSOCIATE STATISTICS,
BEFORE GRANT, AFTER GRANT, BEFORE RENAME, AFTER RENAME,
BEFORE REVOKE, AFTER REVOKE, BEFORE TRUNCATE, AFTER TRUNCATE
Example
* 아래의 trigger 를 system 등의 별도로 관리하는 dba user에서 생성한다.
[예제1] EJ user에서 table과 index에 해당하는 DDL의 실행을 막는 경우
$ sqlplus system/manager
CREATE OR REPLACE TRIGGER ej_no_ddl
before DDL ON ej.schema
WHEN (ora_dict_obj_type = 'TABLE' or
ora_dict_obj_type = 'INDEX')
begin
raise_application_error (-20101, 'Cannot execute any DDL !!');
end;
-> 위의 trigger는 ej user의 schema 에서 Table과 Index 에 대한 DDL이
실행될 때 user-defined error ora-20101 이 발생하도록 한 것이다.
[예제2] EJ user에서 실행되는 모든 DDL을 막는 경우
$ sqlplus system/manager
CREATE OR REPLACE TRIGGER ej_no_ddl
before DDL ON ej.schema
begin
raise_application_error (-20101, 'Cannot execute any DDL !!');
end;
-> 위의 예제는 모든 DDL 이 실행될 때 에러를 발생시키게 된다.
예제1과 2의 경우 EJ user에서 DDL 실행시 아래와 같은 에러가 발생한다.
$ sqlplus ej/ej
SQL> create table test ( a number );
create table test ( a number )
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-20101: Cannot execute any DDL !!
ORA-06512: at line 2
SQL> drop table dept;
drop table dept
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-20101: Cannot execute any DDL !!
ORA-06512: at line 2
[예제3] EJ user에서 실행되는 drop과 truncate 문장을 막는 경우
$ sqlplus system/manager
CREATE OR REPLACE TRIGGER ej_no_ddl
before drop or truncate ON ej.schema
begin
raise_application_error (-20102, 'Cannot execute DROP or TRUNCATE !!');
end;
위와 같이 trigger를 생성한 경우 EJ user에서 table의 생성은 되지만 drop은 할 수
없다.
$ sqlplus ej/ej
SQL> create table test2 ( a number );
Table created.
SQL> drop table test2;
drop table test2
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-20102: Cannot execute DROP or TRUNCATE !!
ORA-06512: at line 2
[예제4] EJ user의 docu2 table에 대한 dml을 막는 경우
$ sqlplus system/manager
CREATE OR REPLACE TRIGGER ej_no_dml_docu2
before insert or update or delete on ej.docu2
begin
raise_application_error (-20103, 'Cannot execute DML');
end;
$ sqlplus ej/ej
SQL> delete from docu2 where docu_id=2;
delete from docu2 where docu_id=2
ERROR at line 1:
ORA-20103: Cannot execute DML
ORA-06512: at "SYSTEM.EJ_NO_DML_DOCU2", line 2
ORA-04088: error during execution of trigger 'SYSTEM.EJ_NO_DML_DOCU2'
* table의 작업을 위해 일시적으로 trigger의 기능을
disable 또는 enable시킬 수 있다.
$ sqlplus system/manager
SQL> alter trigger ej_no_ddl disable;
or
SQL> alter trigger ej_no_ddl enable;

Use event trigger process chain

Hi friends,
I am working on a process chain tuning task.
One request is to change a schedule method of an interrupt from date/time to event.
I know how to generate and utilize event.
My worrying is:
Is an event has duration?
E.g Today's process chain scheduled at 01am,,processing, the interrupt was triggered by event at 04am, but at 10am, the event was trigger again for some unknown reason.
Then,the process chain with the interrupt will be scheduled at 04am tomorrow, but actually, there may be no event for tomorrow as requirement(due to some reasons,we do not like PC run everyday).
Anyone know how to solve this problem?

Martin
You partially answered my questions.
My chain contains both date/time schedule and event trigger.
As is:
Start-date/time schedule daily at 1:00am
step1,step2,,etc
interrupt-now, it is date/time schedule,at 4:00am
other steps.
To be:
Start-date/time schedule daily at 1:00am
step1,step2,,etc
interrupt- event trigger schedule
other steps.
I know how to trigger event by ABAP program.
My concern is:
Today afternoon, someone run this ABAP 10 times to generate 10 events,what will happen tomorrow?
Actually,according to business requirement,tomorrow's process chain(interrupt below part) shall not be ran.
