Is it possible to STOP Polling?

I have created a system with 14 sites. Each having its own Modbus address. All the sites are not ACTIVE. They will be installed at a later date. As the customer installs RTU's all they need to do is flip a switch to enable it. Right now there is only one active site.
I would like to know if there is anyway to shut off the Modbus driver so that it will not produce a COMM Fail alarm. I have connected a Switch to the Poll Rate Member. This stops the polling but an alarm is still generated. This is more of an annoying problem then a functionality problem.

You have to delete whatever is connected to the modbus Poll Rate datamember (just leave it blank). Connect FALSE (or a Pushbutton) to Poll datamember.
This will avoid the modbus object to poll, or it will just poll when you push the Pushbutton.
However, when you create a new connection to any modbus datamember (e.g. creating an expression to 40001) it will immediately verify the connection and raise the error 'no communication response from modbus secondary'.
To disable this Immediate Poll, the lookout developers implemented once a hidden modbus.ini setting:
[all]
SkipImmediatePoll=1
[mymodbusobject1]
SkipImmediatePoll=0
This setting in your modbus.ini will disable to make the connection verified. (However, not for your mymodbusobject1)
Hope thi
s helps

FTP Adapter stops polling on updating descriptors in BPEL Console

I have a bpel process activated by a file in a FTP dropzone. An FTP Adapter listens to this dropzone. I have set up a few preferences (Deployment descriptors) for this process. Once when I update any of these user defined preferences, ftp adapter stops polling the dropzone.
Any idea why this happens?
Workarounds?

Hi Shishir,
Bouncing the server working most of the times, which might not be possible all the time in case of production environments ;/
Do you find any errors on the logs when the cube engine and activation loggers are set to DEBUG ?

How do you know that the DB Adapter has stopped polling

Hi,
Is there a smart way to figure out if the DB Adapter has stopped polling a table ? [We are using logical delete polling strategy].We are looking for a better alternative than just verifying the entire laundry list of tables for the markUnreadValue after every polling interval.
rgds,
Ram

Thank you for your post. Although this is a feature for Buzzword, right now it's not possible to know if someone has viewed a file you've sent via Share. We are working to integrate Share/My Files/Buzzword so that this will be corrected in future.
Let me know if you have additional questions.

DB Adapter stops polling intermittently

Hi,
We have been observing that the DB adapter on our BPEL 10.1.3.4 ( MLR#9) process manager stops polling the database every now and then.
We then have to kick-start it by updating the POLLING_INTERVAL property on the descriptor page via the console ( This property has been explicitly exposed to control the polling interval from front-end).
Although this has been observed pre-MLR#9 as well we are still unable to find the cause behind this. If anyone has faced a similar problem can you please share your experience and possible resolutions for the same as well.
Thanks,
Shishir

Interactive Report - is it possible to stop a column being hidden?

I have an interactive report region where i have a column that has a link that performs an action, in this case it links to a screen where the user can then add a row. I want to make this column mandatory and not let the user hide it. I can remove other functionality, but cant seem to control the hide/show functionality.
anybody got any ideas?

Dear Hemanth,
To your question:
"Is it possible to stop a campaign from being cancelled if it has purchase orders attached to it, using standard functionality".
This might be possible with a BADI implementation. In enhancement spot CRM_MKTPL there exist a BAdI CRM_MTKPL_OL_OBJ where the interface method CHECK_BEFORE_DELETE is offered.

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.

Sender File adapter stops polling

Hi All,
We have a strange issue. A sender File (NFS) communication channel which was working fine, suddenly stops polling.
The cache, is upto date. There are no errors in the channel monitoring. In fact the polling logs are being recorded in the RWB showing successful polling. But the channel does not pick up the file which is lying in the file location. Channel has been working fine till then.
Finally we had to create a new communication channel with the same configuration which picked up the file instantly.
Is this a known issue with File adapter and is there a solution to prevent this situation from happening.
Regards,
Sathya

In fact the polling logs are being recorded in the RWB showing successful polling. But the channel does not pick up the
file which is lying in the file location. Channel has been working fine till then
Did you checked if the adapter was locked out? Normally this is the reason....happens with FILE and JDBC....channel shows successfully processed but there is no message that is actually passed.
Needs to unlock the adapter from VA....SAP Note available mentioning this problem.

Abhishek.

Is it possible to stop the system time outs on my imac ,i have tried 5 times in the last 24 hrs.each time it will go for maybe 3hrs and then times out.each time i have to start the download all over again,thanks,

is it possible to stop the system time out on my imac? i have tried 5 times in the last 24 hrs.it will run for approx.3hrs,and then times out and i have to start

What is the url of the file your are downloading?
What web browser are you using?
What type of connection do you have to your isp? phone line, dsl, cable, fios...
Try iCab. It lets you restart a download.

File Sender channel stopped polling on FTP site

Dear all,
We have many file to Idoc interfaces running in production and all are they good.
Yesterday we faced one issue, one of the interface's sender communication channel stopped polling and didn't picked the files from FTP.
There was no error on communication channel monitoring and it is green.
We stopped & started the channel then started picking the files. But this is not usual behavior of file adapter.
We found one SAP Note 1083488, according to this note, we are in the latest SP level( PI 7.0 SP 14). So not required to apply this patch my case.
What should i do to not to face next time

Hi Bhavana,
Check the below Q & A.....
>> Q: After configuring a large amount of File Adapter sender channels, the J2EE Engine becomes very slow and some services start to block. How can I solve this issue?
A: Up to and including XI 3.0 SP13 each File Adapter sender channel permanently consumes a J2EE application thread. To solve this issue, increase the number of configured J2EE application threads using the SAP J2EE Engine Config Tool ("cluster-data" -> "Global server configuration" -> "managers" -> "ApplicationThreadManager" -> "MaxThreadCount").
Starting with XI 3.0 SP14 / PI 7.0 application threads are allocated on demand by the File Adapter and returned to the thread pool after it has finished the polling sequence, so thread shortage situations will typically occur much more rarely than with earlier SPs.
Also as said by Other SDN'ers check the locks.
Thanks,

JDBC and FTP sender channels stop polling

Hi,
We have a great volume of sender JDBC and FTP sender channels.
For this reason there is nothing unusual to have temporary error connections.
Several months ago, with an XI 3.0 system, sender channels recover its functionality automatically when temporary error connection is solved.
But now, he have migrate to a PI 7.1 sytem, and in the same scenario and configuration, sender channel stop polling after a temporary error . In cc monitor this channels remains in green status and there were no signs of stopped interfaces.
Timeouts are correctly defined and there is no difference between channel configuration in our Xi and PI system.
How to solve this problem?
Thanks, in advance.
Carme.

Thanks for your fast response, Stefan.
After writing this post, i ask the same question to our basis team and we are in the latest sp.
¿do you know if there is any note or can you provide me some additional information?
I'm not able to find any note about this issue...

Carme.

PI 7.1 File & JMS Adapter stops polling at random times

Hi All,
IN PI 7.1, at random times, the File Adapter stops polling. But status is green in RWB.
It starts working after the restart of File Service.
Any idea why this happens? (We don't use FTP Protocol)

Yes Ravi. We recently migrated to PI 7.1 from PI 7.0.
We dont use AAE.
We are on Support Pack 7.
"Adapter Framework is changed in handling threads on the backend in SAP PI 7.1"
what impact it might have on the File Polling?

Sender JDBC - Stops polling

Hi All,
For some of the sender jdbc channels, we face locking issue. The channel monitor keeps showing same log 'processing Started'. Based on sdn threads, we tried to remove the jdbc lock in Netweaver Administrator. But it didnt work. As per the sap note
Note 1083488 - XI FTP/JDBC sender channel stop polling indefinitely(04/04S), planning to try with taskTimeOut parameter.
But what is the optimal value to be given for this parameter? Then could the Transaction Level be kept to Default? Hope it will not lead to any message loss.
The PI version is 7.1 and service pack level is 4.

Hi Aarthi
According to JDBC Adapter Note 831162.
Q: During JDBC receiver message processing I see that some messages are in "delivering" state forever. How do I solve this?
A: Please set the receiver channel configuration Exactly Once handling parameters as "local" and "redo". The configuration setting "local" and "error" setting is some times prone to deadlock situations at the DB table level.24.
Also check question 28 in SAP JDBC Adapter Note 831162.

Is it possible to stop APEX using a cached query?

I was hoping that the issue where report regions sometimes show the error: "ORA-06502: PL/SQL: numeric or value error: NULL index table key value" would be fixed in 3.1.1 however it seems not to have been (We have had it several times now). The workaround seems to be to change the query slightly such as selecting NULL as an additional column and then hiding that column.
This obviously only works AFTER the issue has occured, ie, after we have received a complaint from someone!
Is it possible to stop APEX using the cached version of some queries altogether? The ones we are calling are quite simple and so will not give that much overhead.
Thanks.

I've actually found several threads on this from the past:
ORA-06502: PL/SQL: numeric or value error: NULL index table key value
http://kr.forums.oracle.com/forums/thread.jspa?threadID=644172&tstart=120 (This thread states the problem has been fixed however it would appear either it hasn't or there is a similar bug elsewhere.)

Is it possible to stop auction earlier than scheduled?

Dear SAP gurus,
We are using SRM server 550 and SP08 and we are using LAC. As a purchaser, is it possible to stop auction earlier than scheduled? I see one stop button there, but if i click stop button before the time is up, the system just give me message that the specified time has not been reached.
Best regards,
John.

Hi John,
this is the standard behaviour. An auction cannot be stopped before the scheduled
end date. Only option is to make the time period longer, but not shorter. That's the
current standard with one has to live with.
Cheers,
Claudia
