Update dynamically Polling Frequency

Hi
Can any one help me how to update dynamically the polling frequency for the adapters(database,file) without redeploying the code again.
Thanks in Advance

No issues with my adapter the changes are reflecting only when i restart the server.
we are on SOA 10.1.3.3 with MLR#7.
My question is can we change the polling frequency value dynamically without restart of the server and without redeploying the process in to the server.
But after setting the activationAgent property also we need to restart the server to apply the changes.
Is there any alternative to update the polling frequency dynamically without restart the server and redeploy the code
Thanks

DB Apdater Polling in 11g does not update the polling the column

I have simple SOA11g process in which we are polling a table using DB Adapter:
1) The polling column is process_flag and the read value is Y and unread value N.
2) I inserted the record in the table withe process flag as N.
3) The polling begins and the Composite instance is fired.
However this process continues in an endless loop, polling the column again, after the time set in "Polling Frequency" and firing instance again. What I inferred from all this, is that the polling column i.e. process_flag is not getting updated after it's being polled. When we checked from the backend, the process_flag is always 'N'.
Has any one faced this issue and resolved it?

Hi
Please check what is the PollingStrategy used in the adapter configuration,it should be LogicalDeletePollingStrategy.
For example the configuration in the .jca file looks as shown below
<property name="PollingStrategy" value="LogicalDeletePollingStrategy"/>
<property name="MarkReadColumn" value="STATE"/>
<property name="MarkReadValue" value="P"/>
Thanks

Schedule BPEL with polling frequency

Hi All -
I have a BPEL process which receives the file from file adapter and has polling frequency of 5 minutes.
But my process starts after 12.00 midnight. so I want to schedule the BPEL process after 11.30PM to 1.00AM and in between only it should poll.
Can it is possible? I just want to avoid polling all the 24hrs.
I am usning SOA 10.1.3.4.0. Can I use the below in this version, where I have to use te below, if it is correct?
<activationAgents>
<activationAgent className="oracle.tip.adapter.fw.agent.jca.JCAActivationAgent"
partnerLink="FileFtpInboundPL" heartBeatInterval="10">
<property name="schedulerCallout">DefaultSchedulerCalloutImpl</property>
<property name="endpointScheduleOn">*0 6 1 ? * **</property>
<property name="endpointScheduleOff">*0 8 1 ? * **</property>
</activationAgent>
</activationAgents>

Hi James,
Let me explain my process:
1. First process:
I have BPEL process which starts with recieve activity on database adapter. Database adapter has a polling on database table inserts or updates.
So whenever there are inserts and updates this BPEL process get starts. My business process say the table insert and update is going to happen in between 23:00 PM and 01:00AM. So I want to know how BPEL do polling? When I say database polling it must be looking for 24X7, and when i t gets the file it picks, so is there any way I can say the BPEL to do polling only withing the time frame.
So what ever solution we were discussed of activation agent till now in mail thread applicable on this or not?
2. Second Process.
I have asynchronus BPEL process which starts with wsdl client getting some input as payload, and I want to start this process at 23:00PM, is it possible with activation agent. The client partner link is not an adapter.
Regards,
Sreejit

Run-time Polling Frequency Control

We would like to use our bpel process in two ways:
1. Batch Update type transmissions (freq = nightly)
2. Immediate transmissions
Is there a way to control at run-time the polling frequency? Ie, is there a way to pass the value to the db adapter?
Thank you.

Hi.
For ur last point, u can take a look to the API: http://docs.oracle.com/cd/E21764_01/integration.1111/e10226/soaadmin_apimanage.htm#SOAAG97341
hope this helps

Smart playlists no longer update dynamically

I have several smart playlists that have a couple of rules... one based on rating and one based on whether or not it is present in a regular playlist. When I change the rating of a song so that it no longer meets the smart playlist's criteria, it remains in the list. It will not update until I sync with the PC. The other criteria, the "regular" playlist, isn't updated... and is present on the iPod as well in my iTunes library, so that's not the issue. I'm running the latest greatest version of iTunes and the iPod touch is a model PD721LL/A, version 8.2; it has over 15GB free, so space isn't a challenge either.
I suspect that there is some sequence of settings that will allow this to update dynamically, but I'm not sure what that would be or where to even attempt it.
Any suggestions would be greatly appreciated!
Thanks in advance,
Laura Tieri

My results differ from yours.
With iOS 4.0x, 4.1 and 4.2x my smart playlists with live updating were broken. It would start with track 1 of 5, then 2 of 4, then 3 of 3, 4 of 2, then would generally crash the iPod app. If I left the playlist and re-entered it would have removed the entries already played, but I would find that some of the entries that should have played had actually been skipped in m playlist.
With iOS 4.3, my playlists are properly working for me again. Now they play 1 of 5, 2 of 5, 3 of 5, ... If I return to the playlist while it is playing, I see that the entries that have already played are removed, and if I leave the playlist to return later, it starts over a 1 of 2, 2 of 2...
I have posted another thread of how I have my playlists defined, so perhaps that would help you. I do recall that there were some conditions that used to cause problems if used in a smart playlist.

File adapter polling frequency is not consistent in SOA 10g!

Friends,
I have used file adapter for polling files in a service in SOA 10G env. with polling frequency 3600 secs. However, i have noticed file polling is not happening at 60 mins interval, instead some times files getting polled in less than 30 mins but again after sometime its polling correctly in 60 mins interval. I am not sure what could be the reason but i need a solution urgently. Please help!

Could be the managed servers in the cluster are not in sync.
I faced DB JCA adapter sync issues because of Oracle soa suite bug.
You could check whether any sync issues are there with File adapters.

Where do I set the polling frequency for Technical monitoring in Solution Manager 7.1 SP10 ??

Hi All,
I am customizing my technical monitoring templates and would like to know :
1. Where we can set the polling frequency for each metrics for triggering alerts through Technical monitoring in Solution Manager 7.1 SP10 ??
2. Is it like each time our threshold is breached, it will send an alert irrespective of polling frequency ??
I know the data collection interval time for each metrics in technical monitoring template but the as per my observation the polling frequency is different.
Need your guidance.

Manish K

Hi Javier,

FTP Adapter restrict polling frequency active time frame in a day

Hi All,
Is there anyway I can restrict FTP adapter polling frequency to be active during a particular time frame of the day. Say, my service should poll the incoming location for Sales order data for every hour during business hours of the day.
Thanks,
AG

Hi
SOA Suite 12c will expose Oracle ESS as the scheduler.
ESS will allow you to schedule soa composites / OSB services etcand allow you to enable / disable them based on jobs, which is what you desire.
12c SOA Suite is expected later this Summer.

Smart Playlist's not updating dynamically

Hi,
There seems to be a little glitch in the smart playlists (SPL) on my touch 2G. I used to manually manage the music on my device and I noticed no issue with the SPL's being dynamic. However I started syncing the music recently and I observed that the SPLs wouldn't update dynamically on the device.
For example, I have a SPL called Unrated that contains random songs that are not rated by me yet. When I rate them on the device, I expect them to disappear from the Unrated SPL, which is not happening (used to happen when i was manually managing music).
Am I missing something? Please help!
Thanks - iDeer

Dynamic update of smart playlists when playing music untethered on an iPod touch 2G set to manually manage music is broken with the latest iPhone 3.0 Software Update for iPod touch. Here we go again on this issue. It seems to be broken or purposefully disabled on every other update for the iPod.
On a side note, I noticed that my iPod now occasionally displays a wait screen when opening Music. I found this happens when I alter my playlists in iTunes.app, then disconnect the iPod for a session of untethered listening. Perhaps the iPod is actually building the smart playlists then, perhaps not, perhaps a smart developer will take advantage of this to trigger the smart playlist updating.

Can I use polling frequency for Database Adapter

I need to use Database Adapter that acts like FileAdapter. Can I set polling frequency for my Database Adapter, so that the adapter can query every 5 secs?

You can use polling feature when you configure your DB adapter Operation Type as "Poll for New or Changed Records in Table"
If you use Adapter configuration wizard it will promot for "Pollling Options" and Polling Frequency is the option which you can configure in seconds, mins or hrs

Smart Album Not Updating Dynamically

I recently upgraded to iPhoto 11. My Smart Albums now no longer update dynamically. For example, I have a smart album that contains the last 3 months of photos. It does not update after I import photos from my camera. I have to manaully edit the settings for the smart album and click ok. I don't change the settings, just edit and click ok.
Why aren't the smart albums dynamically updating?

Can i keep configuration settings (polling frequency...) outside BPEL

Dear All,
Can i keep configuration settings (polling frequency and other which are typically set in BPEL adapter outside BPEL
so that at runtime BPEL will look at this configuration file instead of settings inside BPEL.
Regards
Arc

I think you can. If you define them as properties in the Adapter wsdl (by prepending a $), then you can set their values in bpel.xml. And the values in bpel.xml are exposed in the bpel console under the descriptors link. so you can modify these values at runtime, without having to undeploy the bpel process.

How to dynamically adjust Frequency, Phase and Amplitude for a Generated Sine Wave in C/C++?

Hi,
I wonder if anybody know how to dynamically adjust Frequency, Phase and Amplitude for a Generated Sine Wave in C/C++? This is a part of my project: I need to dynamically generate a sine wave voltage signal by some calculation using the data from a simultaneous analog input and another signal.
Your help will be appreciated so much!
Marlon

Hello Marlon,
Here is an example of changing frequency and ampliude for an E-series device in Labwindows/CVI. The programming should be similar in C for your S-Series device. As is says on the linked webpage above, this process is going to be very processor intensive since you will continually be creating a buffer.

DB polling Frequency Configuration

Hi All,
I have a requirement to make the Database polling frequency and the number of records being picked up in that interval to be configurable. If we change the DB Adapter polling configuration every time, we have to re-deploy the code. I want to know how it can be done from the console so that it allows us to both configure the DB Adapter polling configuration as well as not to re-deploy the code every time we change the configuration based on load.
The version of SOA Suite being used is Oracle SOA Suite 11g.
Any inputs on this would be of real great help.
Thanks,
Vishwanath

Yes. Above answer works on ESB too. I mean ESB initiating with requried configs and routing to BPEL process.
In BPEL, I have seen 'Deployment Descriptor' which is meant for run-time variables. I don't think these can be used for configuring the adapter itself.

Polling frequency of AQ adapter

Can we set the polling frequency for AQ adapter during Enqueue operation in 10g?
Regards
Ayush

We are facing a similar issue but a slightly different scenario. Following is the setup:
- Oracle SOA Suite 11.1.1.3.
- BPEL process (within a Composite App) using AQ Adapter reading messages from a AQ queue (corresponding to a subscription to a Business Event) in Oracle EBS.
- Huge number of messages backed up in the queue: delay of between 10 secs to 1 min between consecutive dequeue logs noticed in the BPEL process.
The 'DequeueTimeOut' parameter is explained as "It is the interval after which the dequeue() API will time out if no message is received on the inbound queue.".
But what if there a lot of messages in the queue waiting to be processed? How can we increase the polling frequency so that messages are drained immediately, or is this the default behavior?
Any response is appreciated.
Thanks,
- Hari Nadathur
