Portion of buffer

Hi,
I am sending spool request related output to a file using the function module RSPO_RETURN_ABAP_SPOOLJOB.
is there any function module to select only some portion of this buffer/output?
for example: the total output contains 5000 pages.
but I want to select only 1500 pages -> transfer to file
again select from 1501 page to 3000 pages -> transfer to file.
this is bacause, in production system the number of pages will be millions, which is causing overflow error.
Please help me

I've seen this with properly sized servers with very little Exchange load running. It could be a number of different things. Here are some items to check:
Confirm that the server hardware has the latest BIOS, drivers, firmware, etc
Confirm that the Windows OS is running the recommended hotfixes. Here is an older post that might still apply to you

Setup a perfmon to capture data from the server. Look for disk performance, excessive paging, CPU/Processor spikes, and more. Use the PAL tool to collect and analyze the perf data -

Proper paging file configuration should be considered for Exchange servers. You can use the perfmon to see just how much paging is occurring.
These will usually lead you in the right direction. Good Luck!

Injecting DTMF event in the midst of RTP media streaming?

Hi all, I am attempting to implement a mechanism that allows me to inject DTMF RTP events in an RTP media stream. This is useful in telephony applications where the users are prompted to enter digits while being served by automated voice services such as answerinng services or tele-bankings etc. So basically my approach is to extend Sun's RTP packetizer and intercept outgoing packets when necessary and replace them with the appropriate DTMF RTP (RFC 2833) packets. Sounds simple enough. So I derived my custom packetizer from com.sun.media.codec.audio.ulaw.Packetizer, and over-ridden method process(). Normally my packetizer's method process() simply delegates the functionality to its parent class's process() method. When a DTMF digit is required I'd take the outputbuffer generated by the parent's process() and modify its header and payload to turn it into a DTMF RTP packet. The problem is that the class RTPHeader is so limited, there is no way to set the payload type, sequence number, ... And the documentation is precious few and far in between. If someone has solved this issue, or if you have a reference to some documentation that describes the inner working of JMF's codec chaining, I would appreciate some pointers. What I need to know is:
- What JMF does with the Buffer objects between stages (from one codec to the next)?
- The data portion of Buffer is an Object of arbitray class, what on earth does JMF do with that?
- How does JMF take a Buffer object and turn it into a UDP packet?
- How do I go about creating an RTP header and fill it with the information (payload type, timestamp, sequence number, ...) that I want?
Thanks in advance,

I don't know what the heck RTPHeader represents but it sure doesn't seem to conform to RFC1889. And also, it seems the UDP RTP packets are formed somewhere after the packetizer and before the RTP connector, someone oughta jot all this down in a book. So anyway, using my own RTPConnector implementation I have some control over the outgoing/incoming RTP packets, to access and manipulate the real RTP header (not RTPHeader), I devised a new class that takes the RTP packet buffer and provides an API to examine and manipulate some RTP info directly on the buffer without doing any unecessary data copy (you guys can extend it to do more as per your requirement):

ESE - Event Log Warning: 906 - A significant portion of the database buffer cache has been written out to the system paging file...

Hello -
We have 3 x EX2010 SP3 RU5 nodes in a cross-site DAG.
Multi-role servers with 18 GB RAM [increased from 16 GB in an attempt to clear this warning without success].
We run nightly backups on both nodes at the Primary Site.
Node 1 backup covers all mailbox databases [active & passive].
Node 2 backup covers the Public Folders database.
The backups for each database are timed so they do not overlap.
During each backup we get several of these event log warnings:

We've rescheduled the backups and the warning message occurences just move with the backup schedules.
We're not aware of perceived end-user performance degradation, overnight backups in this time zone coincide with the business day for mailbox users in SEA.
I raised a call with the Microsoft Enterprise Support folks, they had a look at BPA output and from their diagnostics tool. We have enough RAM and no major issues detected.
They suggested McAfee AV could be the root of our problems, but we have v8.8 with EX2010 exceptions configured.
Backup software is Asigra V12.2 with latest hotfixes.
We're trying to clear up these warnings as they're throwing SCOM alerts and making a mess of availability reporting.
Any suggestions please?
Thanks in advance

Having said all that, a colleague has suggested we just limit the amount of RAM available for the EX2010 DB cache
Then it won't have to start releasing RAM when the backup runs, and won't throw SCOM alerts
This attribute should do it...

A significant portion of the database buffer cache has been written out to the system paging file.

Hi,
We seem to get this error through SCOM every couple of weeks. It doesn't correlate with the AV updates, so I'm not sure what's eating up the memory. The server has been patched to the latest roll up and service pack. The mailbox servers
have been provisioned sufficiently with more than enough memory. Currently they just slow down until the databases activate on another mailbox server.

I have the same issue. This is a single-purpose physical mailbox server with 320 users and 72GB of RAM. That should be plenty. I've checked and there are no manual settings for the database cache. There are no other problems with
the server, nothing reported in the logs, except for the aforementioned error (see below).
The server is sluggish. A reboot will clear up the problem temporarily. The only processes using any significant amount of memory are store.exe (using 53GB), regsvc (using 5) and W3 and Monitoringhost.exe using 1 GB each. Does anyone have
any ideas on this?

Brian,
We had this event log entry as well which SCOM picked up on, and 10 seconds before it the Forefront Protection 2010 for Exchange updated all of its engines.
We are running Exchange 2010 SP2 RU3 with no file system antivirus (the boxes are restricted and have UAC turned on as mitigations). We are running the servers primarily as Hub Transport servers with 16GB of RAM, but they do have the mailbox role installed
for the sole purpose of serving as our public folder servers.
So we theroized the STORE process was just grabbing a ton of RAM, and occasionally it was told to dump the memory so the other processes could grab some - thus generating the alert. Up until last night we thought nothing of it, but ~25 seconds after the
cache flush to paging file, we got the following alert:

So it seems as if the Forefront Protection 2010 for Exchange inadvertently trigger the cache flush which didn't appear to happen quick or thuroughly enough for the transport service to do what it needed to do, so it freaked out and performed the subsequent
actions.
Do you have any ideas on how to prevent this 906 warning, which cascaded into a transport service outage?

Constructing a buffer to hold bytes going to socket

I'm a newbie and struggling with a project to construct a multi-threaded Web server that enables a browser-client to access an HTML file. I've constructed a 1K buffer, but if I want to examine various file transfer rates with different file sizes, I have to recode and recompile. How do I construct the buffer so that I can change the transfer rate and the file sizes without having to recode/recompile? The portion of my code relating to buffer construction is as follows:
private static void sendBytes(FileInputStream fis, OutputStream os)
          throws Exception
          //Construct a 1K buffer to hold bytes on their way to the socket
          byte[] buffer = new byte[1024];
          int bytes = 0;
          //Copy requested file into the socket's output stream
          while((bytes = fis.read(buffer)) != -1)
               os.write(buffer, 0, bytes);
     private static String contentType(String fileName)
          if (fileName.endsWith(".htm") || fileName.endsWith(".html"))
               return "text/html";
          if (fileName.endsWith(".jpg"))
               return "image/jpeg";
          if (fileName.endsWith(".gif"))
               return "image/gif";
          return "application/octet-stream";
}

Use a system property. When you run your program:
java -Dbuffer.size=4096 ...
Then in your code:
int bufsize = Integer.get("buffer.size", 1024).intValue();
byte[] buffer = new byte[bufsize];

Intercepting image buffer data

I'm trying to develop a program which needs some image processing to occur on the stream of data being drawn to the screen as displayed by the camera. I don't actually need to capture the video, just process portions of the screen space.
How should I go about intercepting the data being drawn to the screen buffer?

What are all information brought into database buffer cache ?

Hi,
What are all information brought into database buffer cache , when user does any one of operations such as "insert","update", "delete" , "select" ?
Whether the datablock to be modified only brought into cache or entire datablocks of a table brought into cache while doing operations i mentioned above ?
What is the purpose of SQL Area? What are all information brought into SQLArea?
Please explain me the logic behind the questions i asked above.
thanks in advance,

Hi orafad,
I have learnt MemoryArchitecture .
In that documentation , folowing explanation are given,
The database buffer cache is the portion of the SGA that holds copies of data blocks read from datafiles.
But i would like to know whether all or few datablocks brought into cache.

Dynamic history size of xy chart buffer

Hi all..
My question is that when I wanna plot dynamic xy graph I should use xy chart. Till here everything is ok. But the option""history size"of xy chart buffer forces me to determine how many points of history data will be displayed. But what i want is that not fixing it, i wanna see all measurement points till i stop the measurement. thats why i connected to history size option to loop number indicater so that after each measurement i would be able to see all the previos datas till i stop the loop. But it doesnt work!! Does my approach is wrong?

Sima is right.
You cannot have an unlimited history size on a computer with limited memory and resources (Yes, even gigabytes is not infinite). If course you can make your own history buffer by growing the x and y data in shift registers, but at one point during run the system will bog down due to constant memory reallocation operations. Also you cannot possible display more data that fits on a typical screen.
Typically there is some knowledge on an upper boundary, so you can preallocate suitable buffers. If the history is bigger than fits in memory, stream to disk and add some mechansims to browse through history data by reading selected portions back.

How to ignore DAQmx buffer errors ?

Hi,
In my application, I have to start the data acquisition of analog inputs (PCI 6025E)so that it could be read when the uses wishes to through a user interface VI. In addition to this, I also have a background thread that reads two of these AI ports every 250 msecs. However, by the time the buffer is read it has probably been overwritten atleast once and then it throws this error window saying buffer was overwritten etc. I think the buffer is a circular buffer and if so buffer being overwritten doesn't affect my application. So, is there a way I can avoid this error window from popping up ?
Thanks,
Sharmila

There might be a couple of ways out of this. If you create a functional global (also known as a LabVIEW2 style global)you can have it written too by your DAQ portion, and read from elsewhere. You can make this LV2 global act as a circular buffer, allowing you to read from it when ever you need to, but allowing the DAQ to write to it when ever it needs to. There has been a lot of discussion on the construction of LV2 globals, so you should be able to find the information.
Additionally, in the recent versions of LabVIEW there is an option (under the tools/option/block diagram menu pulldown) that allows enabling automatic error handling. What this does is cause an error dialog box to pop-up on any vi you use that has error handling that you haven't "handled" by wiring the error out to something else. Unchecking this may prevent the popup, I don't know whether the vi generating it will then just continue or whether it will need to have it or some earlier vi "reset". This is a useful feature, particularly in development and debugging, although I prefer to intentionally handle errors when I'm designing my code as it forces you to think about the various possible input cases that might fall outside of what you really wanted to happen.

Does buffer cache size matters during imp process ?

Hi,
sorry for maybe naive question but I cant imagine why do Oracle need buffer cache (larger = better ) during inserts only (imp process with no index creation) .
As far as I know insert is done via pga area (direct insert) .
Please clarify for me .
DB is 10.2.0.3 if that matters :).
Regards.
Greg

Surprising result: I tried closing the db handles with DB_NOSYNC and performance
got worse. Using a 32 Meg cache, it took about twice as long to run my test:
15800 seconds using DB->close(DB_NOSYNC) vs 8200 seconds using DB->close(0).
Here is some data from db_stat -m when using DB_NOSYNC:
40MB 1KB 900B Total cache size
1 Number of caches
1 Maximum number of caches
40MB 8KB Pool individual cache size
0 Maximum memory-mapped file size
0 Maximum open file descriptors
0 Maximum sequential buffer writes
0 Sleep after writing maximum sequential buffers
0 Requested pages mapped into the process' address space
26M Requested pages found in the cache (70%)
10M Requested pages not found in the cache (10811882)
44864 Pages created in the cache
10M Pages read into the cache (10798480)
7380761 Pages written from the cache to the backing file
3452500 Clean pages forced from the cache
7380761 Dirty pages forced from the cache
0 Dirty pages written by trickle-sync thread
10012 Current total page count
5001 Current clean page count
5011 Current dirty page count
4099 Number of hash buckets used for page location
47M Total number of times hash chains searched for a page (47428268)
13 The longest hash chain searched for a page
118M Total number of hash chain entries checked for page (118169805)
It looks like not flushing the cache regularly is forcing a lot more
dirty pages (and fewer clean pages) from the cache. Forcing a
dirty page out is slower than forcing a clean page out, of course.
Is this result reasonable?
I suppose I could try to sync less often than I have been, but more often
than never to see if that makes any difference.
When I close or sync one db handle, I assume it flushes only that portion
of the dbenv's cache, not the entire cache, right? Is there an API I can
call that would sync the entire dbenv cache (besides closing the dbenv)?
Are there any other suggestions?
Thanks,
Eric

In addition, you are applying the TRUNC function to the column you are comparing which will prevent any indexes from being used. You should perform the arithmetic on the litterals, not the columns, and set up the range correctly:
AND tp.PRSTART >= TO_DATE('7/24/2006','MM/DD/YYYY)
AND tp.PRFINISH < TO_DATE('9/25/2006','MM/DD/YYYY) + 2This should yeild the same result and will allow any indexes to be used.
Without a formatted execution plan and more info from you, this is just a wild guess as to what part of the problem might be.

Capture a portion of FP image

Hi all,
I like to know how to capture a portion of front panel image? for instance, if i have 2 graphs on fp, i like to capture only one graph image as jpeg to the disk.
Thanks

You didn't mention the LV version you are using.
If you have LV 7.1, then you won't see the sub-menu for the invoke node. Rather once you click on the invoke node, it would be placed on the block diagram and there, you can select the 'Get image' option.
Also there is another option of saving the data as shown in attached image 'Option 2'. If you use the 'Copy data', it copies all the figure data in the buffer (not only the data displayed) to the clipboard. you can then save using any graphics program.
also, If you use the 'export simplided image...' option, you can save a b&W image in either wmf or bmp format to the clipboard or a file.
Hope this helps.

Linking axis to saved buffer in ROM after initialization with 7356

Can you please help?
I can't seem to re-connect an axis to a saved position buffer in ROM after initialization/reset of board.
Details:
When I make a position buffer and save to ROM and then repeatedly run motion command (after using the conifgure buffer.flx with buffer size 0) the motion works just fine. If however, after saving this buffer to ROM, I do some setting changes/initialization ect, then I can't seem to reconnect to this existing buffer in the ROM (I checked and it is there via measurement and automation explorer). So, how do I re-connect to this buffer?
My system specs: Using windows XP sp2 with Labview 8, and the motion card is the PCI-7356.
Thanks very much.

Hi Richard,
I have attached my working VI to this reply. I tested it, and it
works after a reset and reinitialization of the motion controller board.
In the Connect to Buffer and Move portion of your VI, you must
reconfigure the Operation Mode for Absolute Contouring. After a
reset, the motion controller board will have a default Operation Mode
of Absolute Position, so you must change it back to Absolute
Contouring. You must also input the correct number of Total
Points to the Configure Buffer function. The correct number of
Total Points is the size of the array in the selected buffer.
Make sure that the Measurement & Automation Explorer is CLOSED when
you run this program. If MAX is open, its Object Memory Manager
will be making calls to Check Buffer which will conflict with this VI
and cause errors.
I also added Motion Error Handler VIs, so you can monitor any motion errors that might occur.
Sorry for the delay. Hope this helps!

Perl Buffer Issue on Sun Java Web Server 7_3

I currently migrating a website built using Perl on Apache. I was able to setup the Sun Java Web Server to run the site without any errors. During testing we noticed one small anomoly that I just can't figure out. Many of the Perl scripts run for 30+ seconds. The scripts render a portion of the response, HTML, that displays a status to the user. In Apache this displays fine, but in the Sun Java Web Server nothing is displayed until the script is complete. We have the "$| = 1;" command sprinkled throughout the scripts to properly flush the buffer, but that doesn't seem to work. Is there a config option that I'm missing that will help flush the buffer from CGI programs? Any help would be greatly appreciated.

I made the change in my /webserver7/https-webserver.fmr.com/config/obj.conf file. Here is a complete copy of my obj.conf file. I've restarted the webserver instance and still the buffer doesn't seem to be flushing anything to the client until the perl script is done running.
