Set no flow control
When I set the flow control to 'none' under the VISA Property Node and run a port monitoring program, it shows that the controlhandshake is SERIAL_DTR_CONTROL. Is there a way to set the controlhandshake to none? For that matter, is the controlhandshake property related directly to flow control? I am very new at the handshaking properites of serial ports, so I apologize if this makes very little sense. After I set the flow control to 'none' and then read the flow control property, the result is 'none', so I know that LabVIEW is writing it to the port, but why then is controlhandshake set to the serial_dtr_control and not none?
Thanks in advance.

DTR is not a form of flow control. DTR stands for Data Terminal Ready, and it goes hi when the device sees DSR (Data Set Ready) go high. It is just an indicator to say that the device sees the computer. It does not do any flow control. Flow control terminals are RTS and CTS for hardware flow control. Software flow control sends commands called XON and XOFF. I would not pay any attention to what the VISA property node is saying. It has to put something in there.

Want to know what exactly is flow control in odi
Hi Experts
I want to know what exactly is flow control in odi.can anybody explain with an example.i have created a simple interface ie using contol append km .in this both the tables are in one data server ie in different schemas.in this interface i have set the flow control as false.in what circumstances we will use this flow control.
Regards
sreeHi Sree,
Couple of points u need to aware.
There are two ways of Constraint checking in ODI (PK, FK, Condition, NOT NULL etc) using CKM.
FLOW_CONTROL: If u enable this in ur IKM all the constraints checking will be done at I$ table (before target table loading).
STATIC_CONTROL: If u enable this in ur IKM all the constraints checking will be done at TARGET table (after target table loading). In this case u need to DISABLE the constraint first and once STATIC_CONTROL is done then u need to ENABLE it.
So all the violated/errored record will be moved to E$ table in both approach.
Makes sense?
Thanks,

Reg: UTA ports FCoE, 10GbE flow control settings
Could someone shed some light on the flow control settings for UTA ports, below is the scenario.I am working on the configutation of 4 node 3220 custer. We are using this 4 node cluster for FC and NFS traffic. each UTA port on the node used to serve both FcoE and NFS traffic( UTA port logically acting as FC and 10GbE ports) . However, the flow control is set to FULL on the 10GbE logical port to serve the NFS traffic. I think this flow control settings at 10GbE logical port level doesn't effect the FC traffic flow of the UTA port. the flow control settings would be effective on 10GE logical ports only.. Please confirm this... NetApp recommend to set the flow control to NONE and upper layer protocalls can take care of flow control( as per Best practise). If I want to change the flow control setting of 10GbE logical port, does it effect the data flow of logical FC0E port aswell?Now the actual issues is we are using the controllers mostly to serve FC trafic and we are experienceing Performance issues on all the nodes. current ONTAP version on the controller is 8.2p5we are hitting the latency of 50-80ms, I am trying to track the IO on the controllers, IO is not really high when we had the performace issues, But some times disk utilizations and cpu utlization hitting 80%. Performace manager doesn't have the granularity at aggregate level to track what LUN/volumes are casuing the high utlization at aggregate level..I am using the coomands sysstat -M, sysstat -x, netstat , statit commands mainly. However, I am not sure on any other internal porcesses are causing the high disk uitlizations...Please share your ideas on this..Oh.. another point this.. These controllers are flexpod config.....
Hi,We haven't worked on flow control settings.. you mean you are able to Disable the flow control on CNA cards?We have upgraded these filers to 8.2.3P3. at the moment filers are working fine, no performance issues.. However I wanted to disable the flow control on these ports, if possble. But NetApp docs tell that we cann't disable the flow control on the CNA cards. https://library.netapp.com/ecmdocs/ECMP1368834/html/GUID-31241255-4914-46FF-BDB5-A02DCCEABCCA.html Regards,Chandra

With no flow control on the console port, it's common to overrun the port when sending large config files from a terminal emulator. Is there any way to avoid this, other than manually breaking up the file and sending a chunk at a time, maybe by adjusting the console buffer size, if possible?
Michael
Most terminal emulator programs (like Hyperterm, or TeraTerm, or SecurCRT, etc) have a setting where you can specify character delay and or line delay. If you use these parameters to specify some delay you can send the config file (even very large configs) without over-running the console.

ORA-25307: Enqueue rate too high, flow control enabled
I am stuck. I have my stream setup and they were previously working on two of my dev environments well. Now when I get the streams setup the CAPTURE process has a state of "CAPTURING CHANGES" for like 10 seconds and then changes to state "PAUSED FOR FLOW CONTROL". I believe this is happening because the PROPAGATION process is showing an error of "ORA-25307: Enqueue rate too high, flow control enabled".
I don't know what to tweak to get rid of this error message. The two environments are dev databases and there is minimal activity on them so i don't think it's a case of the APPLY process is lagging behind the PROPAGATION process. Has anyone run into this issue?? I've verified my db link works, my stream admin user has dba access. Any help or advise would be greatly appreciated.
thanks, daveAs rule of thumb, you don't need to set GLOBAL_NAME=TRUE as long as your are 100% GLOBAL_NAME compliant.
So, setting GLOBAL_NAME=TRUE will not have any effect if your dblink is not global_name compliant
and if your installation is global_name compliant, you don't need to set GLOBAL_NAME=TRUE.
The first thing when you diagnose is to get the exact facts.
Please run this queries both on source and target so that to see what are in the queues and where.
Run it multiple time to see if figures evolves.
- If they are fixed, then your Streams is stuck in its last stage. As a cheap and good starting point, just stop/start the capture, propagation and target apply process. Check also the alert.log on both site. when you have a propagation problem, they do contains information's. If you have re-bounced everything and no improvement then the real diagnose work must start here but then we know that the message is wrong and the problems is elsewhere.
- if they are not fixed then your apply really lag behind for what ever good reason, but this is usually easy to find.

Paused for Flow Control but no flow occurring
10.2.0.2
Our destination database had problems this AM and it was bounced. The capture process on the source went into "Paused for Flow Control" status and never recovered. Here's the process I went through.
1. There was nothing being propagated according to v$propagation_sender.
2. The apply process was running but was not receiving any messages according to v$streams_apply_reader, v$streams_apply_server
3. I stopped and restarted the apply process - no change.
4. I stopped and restarted the capture process and after the dictionary initilization it went back into the paused state.
5. alter logs showed nothing for either database.
6. dbms_propagation_adm.stop_propagation resulted in an ORA-24082
I finally had to run dbms_propagation_adm.stop_propagation with force=>true and restart it for data to start flowing again, albeit slowly.
So the question is - why? Why did I have to forcefully stop the propagation process and restart it when this is all supposed to be seamless? Is this expected behavior that others have run into and the proces you need to perform whenever your destination becomes unavailable for a time period?
Just curious.
Thanks - BrianI've tried setting up a Streams for schema replication and have run into the "Paused for Flow Control issue". I'm not getting any streams errors so i don't know what's wrong with it.
I'm not that familiar with Streams so i'm not sure where to start to diagnose the problem. I used the Enterprise Manager to set up the streams and tried stopping and restarting the capture process but i'm still getting the "Paused for Flow Control issue". Where is the best place to start to look for a solution?
Thanks! -
Hello,
as I read, WLS provides the possibility to slow down message producers when certain paging thresholds are exceeded. I'm not quite sure, if the slow down of a producer is tied to it's session lifecycle, i.e. if the producer is slowed down only within its current session - or are producers, which are created from a new session, also slowed down right from the start.
It would be great if someone could answer that. Unfortunately I have found nothing about that in the documentation.
Regards,
DirkHello Tom.
First of all, thank you for your quick response. This forum is really working!
I searched for this topic in the documentation, but didn't find anything appropriate explaining the in-depth details of the JMS flow control mechanism. Therefore, I wrote a simple test case (implementation and server configuration is attached at the end of this message) to check the flow control handling for certain conditions. Since there is no API to access the flow control properties of a message producer, I measured the JMS throughput within the test case and tried to derive some conclusions.
Regarding the server configuration:
- I configured one JMS Server (Test_JMSServer) with one Queue (TestQueue). I enabled the message paging at server level, starting at 1000 messages (i.e. message threshold high). The lower message threshold was set to 100 messages. As a paging store a file store (TestPagingStore) was used.
- Message thresholds at destination level was disabled.
- I further configured a connection factory (TestConnectionFactory) for which I enabled the flow control with a max. throughput of 50 msg/sec and a min. throughput of 1 msg/sec. The flow interval was set to 60 seconds, the number of steps was set to 6.
Regarding the test case:
There are 3 scenarios within the test case. Within each scenario
- first all messages are consumed from the queue,
- then 1000 messages are send to the queue in a row, thereby measuring the throughput,
- finally again 1000 messages are send to the queue in a row, thereby measuring the throughput.
The scenarios differ in how the bulk-send operation is performed.
- The first scenario (test_noReuse) creates a new connection for each message to be send.
- The second scenario (test_sessionReuse) creates a new session at the start and reuses that session for sending the messages. A new sender is created of each message.
- The third scenario (test_senderReuse) creates a new sender at the start and reuses that sender for sending the messages.
Here are the results of the test:
==[test_noReuse]=======================
Cleaned up <2000> messages.
Throughput (messages/second): 51 [startMillis=1161249409788;endMillis=1161249429210;messagesSend=1000]
Throughput (messages/second): 62 [startMillis=1161249429210;endMillis=1161249445304;messagesSend=1000]
==[test_sessionReuse]=======================
Cleaned up <2000> messages.
Throughput (messages/second): 231 [startMillis=1161249452773;endMillis=1161249457101;messagesSend=1000]
Throughput (messages/second): 245 [startMillis=1161249457101;endMillis=1161249461179;messagesSend=1000]
==[test_senderReuse]=======================
Cleaned up <2000> messages.
Throughput (messages/second): 790 [startMillis=1161249467351;endMillis=1161249468616;messagesSend=1000]
Throughput (messages/second): 1 [startMillis=1161249468616;endMillis=1161249999226;messagesSend=1000]
To me it seems, that reusing a session has no effect on the message flow control if a new sender is created for sending a message. The only scenario where a throttling occurs (at least it seems to be that way) is the last scenario, where the sender is reused for all messages.
So my conclusion is, that message control flow is superfluous to configure, as long as
- you don't have a small amount of (batch) message producers, each of which reusing a single sender for each message,
- or you have some cache of senders (or a single sender) in your application and reuse the cached senders for sending messages.
The latter is, of course, strongly discouraged, since neither JMS sessions, nor senders are thread-safe. So you need to implement some thread-safe cache and also have to deal with re-creating stalled JMS resources within that cache -- a really non-trivial implementation. Further, if many different threads produce messages, the flow control has no (or at least few) effect on the message load in the server.
I just ask myself, what the flow control was designed for, since the cases where it really applies are rather rare, IMHO. Or have I made some error in the test or in the server configuration?
Best regards,
Dirk

Odi error : Flow control not possible if no key is declared in your target
Hi ...
I have a requirement where I am trying to populate a view(the view some has some pl/sql package running behind the scenes to populate the appropriate tables) on database (oracle11g) using the odi interface.
We are expcetd to populate the view only.
I am encountering this error when i try to run the interface (Flow control not possible if no key is declared in your target datasource).
The view doesnt have any key & I cannot change the key structure of the view.
Is their any workaround for this in the ODI.If you don't have any keys on your table, Flow Control will not be possible as the step of flag rows for update. You must have a key defined in your table to use both resources of ODI.
I recommend you to disable the FLOW_CONTROL option in your IKM and if you need to update your table, you'll have a problem. If you don't have, just disable the Update option also and go ahead with the execution.
TIP: Do not forget of set keys on your temporary tables when uses the IKM of Incremental Update.
Best regards.

Increase of priority flow control counters in a FCoE environment
Hi,
I need some input about what is normal in a FCoE environment in regards to priority flow contol counters.
I see Increase of RxPPP and TxPPP counters on a FCoE end to end enviroment. however we don't see high traffic rates to/from storage array(<1Gbps). Customer have not reported low transfer from storage.
Setup:
CNA hosts - FEX2232 - N5K - EMC-VNX
FCoE end-to-end, No native FibreChannel.
CNA adapters = Emulex.
Is a problem I should look further into or is it normal?
I have read the troubleshooting guide.

I actually already enabled the system qos manually since we run 5.0(2)N2 release.
We will implement FCoE over 5500. What I'm worried about is the warning message I posted above on Nexus 7009s connected to my 5500s after I enabled the system qos.
Could it be originated by the DCBX feature? May I have some problem if 'Priority-flow-control' setting between N5k and N7k don't match? -
Debugging - Process flow control
Hi All,
I am doing initial load for one condition object(R3AS), and when I check SMW01 I am getting BDoc validation Error.
I want to debug the BDoc flow context i.e MI0(validation function module) where Bdoc posting is failing.
I followed OSS note- 432661- Debugging and process support of flow control: Enhancement
Here is the Note:
Symptom
Error analysis requires debugging flow control services.
Other terms
SMW01, Flow Control, BDOC, BDoc, BDoc Message, Flow Service, Update task, qRFC step, asynchronous step
Reason and Prerequisites
Error analysis requires debugging flow control services.
Solution
This feature is available with CRM 3.0 starting SP04 and higher releases.
Usage:
The flow header structure SMW3_FHD is extended to hold a flag indicating debug mode. To debug, set this flag before calling CL_SMW_MFLOW=> PROCESS_OUTBOUND (Parameter IN_HEADER, Field DBGMODE), PROCESS_NOTIFICATION (Parameter HEADER, Field DBGMODE) or PROCESS_NOTIFICATION_MULT (Parameter HEADER, Field DBGMODE). If update task and/or asynchronous tRFC/qRFC step is done, the message is not written into a qRFC queue or tRFC. Instead the message get's a new state 'D01': To be processed (Debug).
The message processing can then be continued from transaction SMW01.
Select messages in state D01 possibly with bdoc type, send date, creation time, and user.
In the list display check the message check box that you want to debug.
Choose function Retry to process.
The message will be processed by flow service function modules in the order shown in transaction SMO8FD. Processing occurs directly. Therefore all active breakpoints can be used to stop processing for further analysis.
I set HEADER-DBGMODE = X, and passed this structure to CL_SMW_MFLOW=> PROCESS_OUTBOUND
But none of the message is set to D01. Anyone have idea where I am missing?
I basically want to debug this validation function module while Bdoc comes in CRM, Any other way other than this OSS note..?
Thanks,
Vijay Rahejawhat the description of the error?
Give details. Just by saying bdoc validation error does not nelp.
Click on the error details icon and see wat it says.
let us know then only can we help

Enabling/disabling flow control on hme0
I found ndd and was able to disable auto-negotiation and set the duplex on hme0 to full but how do I disable/enable flow control on a NIC in Solaris?
Thanks!Hello,
Sorry for bringing up a very old thread,
After doing
ndd -set /dev/bge1 adv_autoneg_cap 0, will it also take care of pause frames? I found that my server running solaris 10 is asking network switch to PAUSE frames. I do not want server to ask the switch to PAUSE it.
So do i need to set flow control off on server and also set following values to 0 on server or flow control off itself on server will do it for me. flow control is off on switch.

Hello again,
Is there any mean to execute more that one time the same XSQL action-element, like this (future XSQL version?):
<xsql:for-each test="{@selectedITEMS}">
<xsql:dml>
DELETE FROM ITEMS
WHERE ItemID = {.}
</xsql:dml>
</xsql:for-each>
Yes the duty can still be transferred outside XSQL, in the form of a DB proc or a custom action-element, but if some form of basic flow control exists/ed here inside XSQL, this would certainly come in handy!
Thanks
JRochA simple way to do this would be to write an action handler that processes the value of the "selectedITEMS" parameter and sets a page-private parameter to the equivalent value with commas between them, then do:
<xsql:dml>
delete from items
where ItemId IN ({@ListOfLitems})
</xsql:dml>
then you do it all in one trip to the database. -
How do I set up parental controls on my apple account, I want to censor the books that she's dowloading. We use the same account Thanks!
Turning off in-app purchases and the App Store itself would be the best bet for you. You can always unlock these features as needed and lock them again.
Apart from restricting purchases, there are a number of other restrictions you can setup. You can even setup a safe browser with remote parental controls from the App Store, like the one from Mobicip. You may find this tutorial to be helpful: How to setup Parental Controls on the iPad.
Hope this helps.

Set cursor in Control String component
Hello:
I would like to set cursor in "Control String" automatically when I open my VI. If I open my VI, cursor should be seen automatically in the text field of "Control String". The user hasn`t set cursor by mouse into this field. Has anybody an idea how can I do?
Thanks!Create a property node for the control on your block diagram and set the Key Focus property value to TRUE.
