A JDBC adapter specific time polling setup

Hi All
I am looking for a way to setup a JDBC Sender adapter to poll at a certain time of day, like 18h00. I have tried to set it up for polling every 60000 seconds and starting that adapter at 18hoo but due to Maintenance weekends, the adapter engine gets restarted and reset my polling time, so I need setup the adapter to poll at a specific time. Can anyone help me with this problem?
Thanks in advance
Clinton

Hi Clinton,
you can go over JDBC receiver adapter and use a BPM with a wait step, where you can put a certain time. If you send only once a day a message, performance of BPM cant be a bottleneck.

JDBC adapter is not polling as scheduled

Hi,
we have observed JDBC adapter is not polling database correctly. adapter is scheduled at every 1 second, but it is plooing for every 5 sec or 6 sec.
is there any way the issue can be fixed?
Thank You,
Madhav

hi,
in my mind, the issue is your polling's choice of 1s !
so to have a real-time exchange whereas you use a polling method to reach a server with is not the PI server itself, and perhaps also not on the same network, by opening perhaps also the database connexion at each request in order to call a SQL request or a stored procedure...
I don't know your complete flow, but if you really need a 100% real time, maybe it should be better to trigger the sender JDBC adapter from outside when (and only when) the data is produced / changed in your database....
Anyway, personally, I never recommend to have a polling of 1s. 10s (and often only 60s) is enough is most of the cases... because after the polling you have the XML conversion, the PI mapping, the sending to ECC, the ECC treatment... all these steps take time, and so the interest of checking of every 1s is (in my mind) clearly reduced by all these steps.
(*) I'm sure if SAP will define a polling in milliseconds, some people would like to use a polling of 1ms, but that's a non-sens...

JDBC Adapter stopped polling

Hi,
our JDBC Adapter is stopping polling automatically.
It seems if the adapter does not process an event for a long time. The adapter is stopping polling.
Can somebody help me?

hi,
can you try using:
<b>"Disconnect from Database After Processing Each Message"</b> indicator
http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
on your test system to see if the same will occur ?

JDBC adapter disconnects, if there are no message processing for 2 days

Hi All,
I have sender JDBC adapter configured, which polls messages every 3 mins.
XI is constantly polling the database (SQL Server) and since there are no messages on weekends, after a certain interval, it disconnects... giving a null exception.
I have checked the advance option "Disconnect from Database After Processing Each Message". still it is giving this error. I am on SP 12.
Can someone please let me know, what could be the reason of this null exception. why does it disconnects if there are no message processing for a long interval.
Any help would be appreciated.

Amit

It means we don't support that file type for doing imports. It sounds like a reasonable request to [add to the Exchange|sqldeveloper.oracle.com] though.

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

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

JDBC adapter - polling application - is this efficient ?

Hi,
I have a scenario that is requesting data via the JDBC adapter from an SQL server system and sending the resultset into BW.
This is polling every 10 minutes with the following statement :
select * from itecs_dummy.dbo.action
where current_timestamp between
convert(datetime, (convert(varchar(13), GETUTCDATE()) + '23:40:00.000')) and
convert(datetime, (convert(varchar(13), GETUTCDATE()) + '23:50:00.000'))
This basically will return zero records 99% of the time as it check the system time is between 23:40 and 23:50
Eventually I will have around 30 JDBC communication channels performing the same frequency of polling but read data from different tables (the system time check will still be the same for each select)
Is this highly inefficent in XI terms ?
Would it not be better to write a simple ABAP to request the data from BW to the JDBC adapter at a fixed time each day therefore cutting out the unnecessary polling ?
Kind regards
Colin.

Hi Colin,
The method you're using is really the only simple solution to workaround XI's lack of a scheduler.
We have about 10 JDBC interfaces live for a year at a large XI client using this workaround. They're polling every 5 minutes and we've never had an issue.
We decided to use this method based on the following:
1) The load on the DB wouldn't be significant. Even if you have a complex DB select statement, the DB optimizes the call and should run fast if the 'where' clause fails. You can check this with your DBA.
2) The load on XI would be greater if we implemented this in another way. Any other solution would likely require BPM which is much more intensive for XI then these JDBC calls.
We chose 5 minutes instead of 10 because of the following scenario which could occur although it's not likely:
- XI polls at 23:41, message is sent
- XI J2EE goes down at 23:42 and restarts
- XI J2EE back up at 23:47
- XI polls at 23:47, message is sent
So in this scenario, you could get 2 messages sent. Since our J2EE stack takes longer than 5 minutes to restart, we resolved this issue by using a 5 minute polling interval.
I think the more elegant and precise way is to make a call from ABAP, but it would be more complex, and put more load on XI due to the use of BPM. If you take into account the above items I think your current approach is the best.
Thanks,
Jesse

Problem with Polling interval at sender side in JDBC adapter

Hello,
I have some problem in investigating one serious issue using this polling interval,
I am using the sender JDBC adapter where i used polling interval as
60(in secs) and 1(in Msecs).
So it comes upto 60.001 secs of polling interval.
There are nearly lots of threads which are in sleeping state on one particular sender channel making the J2EE hang. When i went to look inside the CPA cache i saw that the polling interval was mentioned as only 1Msec rather than 60.001 Secs because of which with in some seconds all the threads are blocked and J2EE hangs due to lack of threads.
Can you please provide some solution to this problem as soon as possible?
Here are few questions which i got when i am doing this process,
1. Is that the polling interval is sum of 60(secs) and 1(msec)?
2. Which value is been read either secs or msecs?
3. Will there be any precedence among those two values(secs and msecs)?
THanks,
Soorya

Poll Interval (secs)
Number of seconds that the adapter must wait if no files are found for processing.
● Poll Interval (msecs)
Additional waiting time in milliseconds.
If you set Poll Interval (secs) to null, processing times will be short and close to real time.
If you set Poll Interval (secs) and Poll Interval (msecs) to null, the adapter is only called once.
● Retry Interval (secs)
Specify the number of seconds that the adapter is to wait before a file processed with errors is processed again.
If the value is set to null, then the adapter is canceled if an error occurs, even if a value greater than null is specified for Poll Interval (secs).

JDBC adapter taking too much time for inserting

we` have given a "update insert" query to be used in the JDBC adapter to insert these records into the database. Consists of 3 tables with 29fields in first, 4 fields in the other two.
While message in XI gets processed in just 1-3 secs, the database processing time goes up to as much as 8 minutes for one record to get inserted.
As immediate solution, is there any way we can have the JDBC adapter process these messages faster? These messages get queued up and hence all the other messages also get queued up delaying the other interfaces. We have a central adapter engine...
Also is there any way we can get alert when the status is in "Processing/To be delivered/Delivering" and the message count exceeds a certain number say 1000

I am using only one receiver JDBC channel
We have been inserting three different table by using 3 different statemets tags(i.e) statement1(for table1),statement2(for table2),statement3(for table3).
My structure is,

You can see we are also using key as well.In the first table we have 28 fields,second & third we are having 4.

Time Limit Exceeded. JDBC Adapter

Hello guys,
we have problem in an interface in production.
The interface is asynchronous and is File -> PI -> JDBC
Some messages have sometimes an error in PI monitorization, and we can see the next error:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- 
- <SAP:Error SOAP:mustUnderstand="1" xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
<SAP:Category>XIServer</SAP:Category>
<SAP:Code area="INTERNAL">SYSTEM_DUMP</SAP:Code>
<SAP:P1 />
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />
<SAP:AdditionalText />
<SAP:Stack>XXXX : XXXX___0000 : Time limit exceeded.</SAP:Stack>
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
It seems there is an error when sending to the JDBC adapter? The concurrency of the adpter is set to 1 and we send 7 messages to the same adapter and the messages are executed more or less at the same time.
Could we have to do some PI configuration about queues? or maybe is about the concurrency of the adapter?
Many thanks in advance.
Regards,
Xavier.

You might need to increase MAXIMUM CONCURRENCY > 1 and set poolWaitingTime > 0 as per SAP Note 831162. By doing this will alow JDBC Receiver to process concurrency the request from Integration Engine.
or you also can try to increase "Recv.maxConsumers" for JDBC Adapter. The current value is 5
In addition above, since more messages are concurrently happening more or less at the same time, I would recommend also to use this parameter setting.... Go to advanced tab in the jdbc receiver channel.
check the option "Disconnect from Database After Processing Each message". This would help if the connection is not immediately return to the other thread after serving the first thread. Plus it is a best practice to follow up.

Only 5 messages at a time being delivered thru JDBC adapter

We have an XI interface that is delivering updates to a SQL Server database through the JDBC adapter. Our problem is only 5 will deliver at a time, and we have thousands to deliver so it takes forever. The messages queue up in 'To Be Delivered' status and eventually get through. Is there a parameter to set which controls how many messages can be delivered through a JDBC adapter at one time ?
Thanks in advance.

How do you deliver these updates? I mean, with a single message or one update per message?
I think that you should try to put all the update in a single JDBC message in order to have them delivered at the same time.

How many records does JDBC adapter can obtain in one polling?

Hello everybody,
I need to do an interface between legacy system and SAP ECC, the legacy systems have a DB so i use the jdbc adapter (sender) and receive the information to SAP ECC with proxy, so i need to activate the polling option from my jdbc adapter working as a sender, i read a table with lot of records, and i need to know how many records does jdbc adapter support when the polling is executed, because is necessary read all records from the table and change the status of the processed field.
Is possible to get all the records from that table in one polling interval (50,000 records aprox)?, or i need to do the polling by blocks of records until finish all records from the table?, the second option, i dont have idea how can i do it.
Regards,
Vicman

Hi again!,
i still working on that, but i have a question, is possible to handle Store Procedure in jdbc adapter?? is supported?, like PL SQL, because i was working in the next query but i don't know if it works and where do i need to locate the query in the Query SQL Statement or in Update SQL Statement field or both? but how?.
DECLARE c_cursor CURSOR FOR
SELECT * FROM tablename
WHERE processed=0
OPEN c_cursor
   FETCH NEXT FROM c_cursor
WHILE @@FETCH_STATUS = 0
BEGIN
   update tablename set processed=1
   FETCH NEXT FROM c_cursor
END
CLOSE c_cursor
DEALLOCATE c_cursor

How to send 1000 records per each time through JDBC adapter

Hi all,
In my JDBC to File scenario, SQL Server database having 10,000 records. I want to split these records into 1000 records and process 1000 records each time. How we can do in JDBC adapter. Is there any options in JDBC adapter. Please give me reply very thanks to all of u.

Hi all,
Thanks for your repsone. I am very happy.
If it sender Jdbc we can write the query. If it is Receiver Jdbc adapter and I want to send the record as 1000 at a time.
You may give this advise that is you can use RecordsetPerMessage option at sender side. But here I want to read all the records and send 1000 records only.
please give me valuable answer.
thanks in advance...

Interface to run at a specific time

Hi
I am trying to let a interface run at a specific time, I have setup the bpm and will probable use the wait step? Is this the way to go, because I was thinking of setting my sender adapter to run let's say every 2 hours and then when it reach 10pm it will let all the data go to the end point?
Thanks in advance
Clinton

Hi,
you can collect all of your messages
(before BPM) and then at 10 let all then start the BPMs

Sender JDBC Adapter issue.

Hi folks,
I would like to know how can I configure a sender JDBC channel without specify a poll interval? I know that I can specify this poll interval with a period of time that I want; it could be in seconds and even in mseconds. But, this can cause a lot of access to the Data Base SQL Server and consequently can cause network slowness.
I would like to know if there is any data base event that can trigger my jdbc sender adapter or any other workaround that can prevent many accesses to one Data Base.
Any ideas are appreciated.
Thanks in advance,
Ricardo.

Hi,
with XI SP19 you can schedule your jdbc adapter easily:
