How to Schedule Poller(Servlet)

Hi All,
I have a servlet that servlet does offline process soem data at EOD.So i need that servlet to run at EOD ( i mean at morning 1 AM) and stop after 1 hrs work then again start tomrrow morning 1 AM .Can i know how to schedule
Regards

Look at the Java Timer class. Use a ServletContextListener to start the timer when the context loads. The Timer can be a context attibute.

How to schedule a servlet to execute at a certain time interval?

Hello,
          I have a requirement to publish content (xml file) based on a time interval
          (say, every 1 hour).
          This has to be done in a servlet/jsp environment.
          I have a servlet which creates the xml file and puts it in the right
          location.
          Is there a way to have this servlet execute every 1 hour (or whatever is the
          time interval)?
          Would appreciate any hints or pointers on this.
          Thnx.
          Mukul


See Weblogic's time services or check out Flux (Sims Computing).
          Out of curiousity, why are you doing this with a Servlet?

Reg: How to Stop Polling of JDBC Adapter without Scheduling the adapter

Dear Gurus,
Here I am having one requirement. My clients wants to send data from JDBC adapter (ORcale System table) to R3 system via RFC.
His Requirement::
1. He is not telling the time of data flow from Oracle server so that based on that we can schedule the adapter in the Communication Channel monitoring (Availablitiy Time Planning) or Else we can Schedule by deciding the setting of the polling interval time.
2. He is telling that When ever he waants to send the data he will place one dummy file in the File Adapter FTP location so that it will became an Indication for u to poll the jdbc adapter and to transfer the data to R3.
3. Untill he keeps the file or gives indication he doesn;t want to communicate with Oracle server due to some security and it s a most important data base he doesn't want to disturb that Oracle Server as so many business are running on that.....
We Proposed::
1. Atleast you need to tell the scheduling time or poll interval time so that we can schedule our adapter.
but he s not accepting for this
2. Atleast U need to give access for Data base to enter one more extra field like STATUS CODE so that we will add one number and we keep on Update in the Update table and based on that Update table statement it will poll.
but he s not even accepting for this
3. Finally we prposed that to create another table in the Oracle SYstem as Dulplicate Table which is similar to Standard Orginal table when ever he wants to pick the data please keep that data in this Duplicate TABle so that JDBC adapter will pick the data from thsi TABLE instead of picking the data from that standard table so that it will not effect any standard table data in the table.
but he s not even accepting for this
We have done some R & D:::
1. WE approached even through BPM and via switch conditions is one scenario
   FILE RECEIVE >SWITCH CONDITION> RECEIVE AND SEND or else EXIT
2. Using correlation in anotehr scenario means correlating File adapter and JDBC and based on one dynamica value it will goes to SEND STEP ( RECE IVE --> RECEIVE --> SEND STEPS )
Even though we know this...concept that...we jsut tried::
In BPM we can control the flow in XI 3.0 but we cannot Stop the Polling of JDBC adapter at backend because one the data comes from FILE adapter it will keep on HOLD untill it receives the JDBC from Oracle then based on the condition or Correlation it will goes futher SEND step means after that file adapter is picking file or not ...what ever it may be JDBC will polls at backend and brings that data to BPM"
Hence sugest me How to Stop Polling of JDBC Adapter without Scheduling the adapter or else using STATUS CODE Update statements in JDBC Tables
Regards:
Amar Srinivas Eli

Hi! All,
Finally I decided to do the scenario in two steps:
1: FILE REQ --> JDBC REQ -->JDBC RES --> FILE RECV
2: FILE RECV --> RFC
But I am getting issue while doing first scenario
Desgn :
I have created 2 Synchronous interfaces :
1) FILE 2 JDBC REQ
In this a) out put message is FILE Req
          b) Input msage:; FILE RES
2} JDBC2FILE RECV
        a) Output mesage;; JDBC REQ
        b) Input Msge :: JDBC Response
Mappings:
1) File REQ-->JDBC REQ
2) JDBC RES-->FILE RES
Interface mappings:
1: FILE 2 JDBC REQ--> JDBC 2 FLE RECV
CONFIGURATION ::
1: One Seder File CC
2: Two reciever CC's one is for JDBC RECEIVER and other s FILE RECEIVER
3; One Sender Agreement
4: 2 Recver agreements
5: One Interface Determination and
6: One RECCV Determination
My Question;;
1. First let confirm whether my development steps are right or not ?
2: Another thing s I am not sure reg Configuration Steps means
whetehr one interface determination and one Receiver Determinations are required or not as these are synchronous Interfaces
3: main Issue is::::
If my scenario s FILE2RFC2FILE then I will get RFC response automatically but here issue is this is JDBC
My reqquirement is By sending one Field from fILE to JDBC REQ it needs to send entire TAbLE records as a Response to file as XML
without having Sender JDBC how can I send the JDBC Res to FILE and If that is the case then again JDBC adapter is polling which is contradict to the client requuirement which i explained above.
pleas suggest me the Detailed steps mainly Colloboration agreements and logical routings and
also explain in detail if i can go for BPM
Also give cleear blogs but before giving make sure that it contains detailed screen shots because aIready gone thorugh
Scenario File-JDBC-RFC
File<-->JDBC Sync coomunication.

How to schedule the process chain fr the report

hai experts,
i have a query which i need to generate for every five hours? i know that we can generate the report thr process chain but i dont know how to build that..
my question is how to schedule the report,how to build the process chain,....
can any one plz tell me how to start this generating report for every five hours
thanks in advance..points will be alloted surely ,i need this urgently..
Suri

First of all you need to Identify the InfoObjects if you want to take up Master Data Loads, and if you want take up transaction loads then select the Data Targets to which the data has to be updated. Then plan the dataflow accordingly.
You want to create a Process Chain, Go to RSPC, and then select the create option and from the Process categories available on the left handside drag and drop the Start process, then define the Variant for the same. In the same way you need to identify the other Process Types available on the lefthand side. For Eg: Start Process>Load to ODS>Activation of ODS Data>Delete Indexes for the InfoCube>Load to InfoCube>Create Indexes>Delete Overlapping Req-->Agg. Rollup.
This is how you need to specify the dataflow, several other Process Types also included based on the requirement For Eg: Sending Mail Alerts when the Job is Success or Terminated.
Also, have a look at this links to make urself clear about the steps in creating Process Chain.

How to achieve poll-based scenarios in Oracle Data Integrator

Hi ,
Could you pleaes let me know as to how to achieve poll-based scenarios in ODI?
I have a requirement where in, ODI has to interface with a JMS Queue for XML messages and write to a DB.
This is not based on a schedule. The ODI interface has to poll for the messages from the queue and write to the DB.
How would I achieve this?
It would help if one can give the required steps to go about this.
I have created a package containing the interface that picks the xml msg from queue and inserts into a DB table. I have generated a scenario for the package. I have modified the MAXMESSAGETIMEOUT in the LKM to 0
then what else I have to do?
I have launched a listener agent; but how would I associate this with the generated scenairo?
Any insights into this would really help!!!
Thanks,
Manoj Nair.

Hi,
ODI will do a SINGLE commit after all the rows have been inserted/updated in to the target table, so dont worry about the "rollback" if the transactions fails.
For the handling failed transactions, you need handle it using CKM by having constraints defined for the transactions and move it to E$ table if its violated.
Hopes this helps.
Thanks,
Guru

How to schedule a concurrent request to run at a specified time/day?

Hi All,
How to schedule a concurrent request to run at a specified time/day (ex: Sunday 12pm)?

Is this to run periodically ?
During the request submission, click schedule, choose the specific days, and click on S = Sunday.
Change the start date on the date of the sunday you want to run, eg : 15-JUL-07 14:00:00, change the end date as well.

How to place a servlet file in Tomcat 5.0?

Hi,
i'm using Apache Tomcat 5.0 as myweb server.i don't know how to set the class path and where to place my servlet and html files,and how to run my servlet file.if anybody knows plz give me a detailed description abt this topic.

Look at the directory structure of your Tomcat installation directory. You will see a webapps directory under that. The Tomcat installation comes with samples ready to run. Look at those and create a similar directory structure under webapps for your application. I don't think you need to worry about classpath. Tomcat should be taking care of all that if you create the proper directory structure.
You run your servlet by specifying a url like:
localhost:8080/servlets-examples/from a browser. This assumes that your installation is using port 8080 which I think is the norm for Tomcat. Here "servlets-examples" is the name of the directory you created. Actually Tomcat 5.0 comes with a "servlets-examples" application. This would be a good directory to look at. You could also run their examples to get a feel for it.
If you are new to servlets, you'll probably have to get a book that explains how things need to be set up. You'll need to create a web.xml for your application. If you look at the servlets-examples directory under webapps, you'll see that it has a WEB-INF directory under it and that directory contains a file called web.xml as well as a sub-directory called classes. This structure is standard accross all application servers because it corresponds to the war (wars are specialized types of jars for web apps) file standard.

Did you read DBMS_SCHEDULER docs:
The calendaring syntax does not allow you to specify a time zone. Instead the Scheduler retrieves the time zone from the start_date argument. If jobs must follow daylight savings adjustments you must make sure that you specify a region name for the time zone of the start_date. For example specifying the start_date time zone as 'US/Eastern' in New York will make sure that daylight saving adjustments are automatically applied. If instead the time zone of the start_date is set to an absolute offset, such as '-5:00', daylight savings adjustments are not followed and your job execution will be off by an hour half of the year.
When start_date is NULL, the Scheduler will determine the time zone for the repeat interval as follows:
It will check whether the session time zone is a region name. The session time zone can be set by either:
Issuing an ALTER SESSION statement, for example:
SQL> ALTER SESSION SET time_zone = 'Asia/Shanghai';
Setting the ORA_SDTZ environment variable.
If the session time zone is an absolute offset instead of a region name, the Scheduler will use the value of the DEFAULT_TIMEZONE Scheduler attribute. For more information, see the SET_SCHEDULER_ATTRIBUTE Procedure.
If the DEFAULT_TIMEZONE attribute is NULL, the Scheduler will use the time zone of systimestamp when the job or window is enabled.
