Reading & Writing from/to OCR

Hi,
Is there a way to read and write the Oracle Cluster Registry.
Are there any API's available for the same.
Thanks

I have a SW application running on all nodes in the RAC Cluster.
The SW needs to write data to a place which is visible to all and can be read by all the other nodes. Also it should be able to gather information (especially about failover), so should be able to read from it.The OCR is not used to as a common data store for CRS applications - that is typically what a cluster file system is used for. This allows the same set of directories and files to be visible to applications on each and every cluster node.
The OCR is specific to CRS and should only be used by CRS software.
I found this link on the internet 'C Application Programming Interface to Oracle Clusterware'
http://download.oracle.com/docs/cd/B28359_01/rac.111/b28255/crsref.htm#CHECGHGI
Yes, if you want to create a cluster application that you want to be managed via CRS. But this requires more thought than simply slapping a few calls together in an application to make it cluster enabled.
Is this the correct way to do it? Can reading/writing from/to OCR lead to fatal errors?Unsure whether it is the correct way for the problem you're trying to solve as that problem is pretty still much unknown to us as you have not described it.
Can one corrupt the OCR? Not if the API calls are used and used correctly.
It is a bit strange to see a posting about using the CRS API itself - usually we write our software in the RAC layer (as PL/SQL and Java stored procedures, using the cluster features of the database instances).
Do you intend to only use CRS? Or CRS with ASM and RAC? And why do you want external C application code to make use of cluster services?

TIFF-VIs for reading/writing from/to files

To whom it may concern,
I'm looking for TIFF-VIs for reading/writing from/to files
for Labview 6 without any add-on package.
Unfortunately I can't use TiffRd04 and TiffSv05 from
Koji Ohashi due to the different file format!
Any hints?
Thank you in advance. Best regards from Germany
Udo Weik

Hi Udo,
did you check these TIFF related libraries? .. maybe one of them is working.
Good Luck

Reading & writing from MS Excel files in Webdynpro ABAP

Dear experts,
We have a requirement to read and write from an MS excel file in a Webdynpro ABAP based application. The application would be deployed on WAS (Web Application Server) which is running as part of SAP ECC on UNIX platform.
What is not clear is
1) If we store the MS Excel template on the server which has UNIX, will the file be recognised for reading/writing programmatically in Webdynpro ABAP? If this works, we have a requirement where the end users will download the excel template and upload the same after filling data into the excel file. The data filled into the excel has to be read and updated in the SAP backend (ECC).
2) There is an article on "Modifying Excel using WD ABAP" at the following link
https://wiki.sdn.sap.com/wiki/display/WDABAP/ModifyingexistingexcelsheetusingWDABAP
But again it is not clear whether this approach will work on Unix based SAP server (ECC WAS).
Thanks
Suresh

I don't know if there is an application in Unix that can read Excel files - if that is what you are asking. However that has nothing to do with this forum. If you are uploading the file to ABAP using Web Dynpro ABAP, then it doesn't matter what Operating System the server is running on. Unix, Linux, Windows - all the processing is done in ABAP and is OS independent. The actual reading of the file in ABAP involves reading either an XML or Text Tab Delimited version of the Excel file however - if you read through the links on manipulating Excel in ABAP.

Reading/writing from the standard streams of a process

Hi all
I try to start an external program trough my java application and then try to communicate it. After the external process has started, I want to send input to it and get output back from it. That, however, doesn't work.
My external process gives some output data when it starts up, and i can catch this with no problem at all.
Thing is, my program hangs while reading from the stream when there is no more to read from it. How can I read and write to the streams without it stopping and hanging?
Here is some source code I use to test this:
//The constructor
   try {
     ProcessBuilder pb = new ProcessBuilder(args);
     //I combine the error stream with the output now, just to get stuff to work. Will change later
        pb.redirectErrorStream(true);
     Process p = pb.start();
     input = new BufferedReader( new InputStreamReader(p.getInputStream()));
     output = new DataOutputStream(new BufferedOutputStream(p.getOutputStream()));
     String line = null;
       //I get this far, but after the last line of input has been read, I the program seems to stop in this while loop
     while( ( (line = input.readLine()) != null) )
               System.out.println(line);
     }catch(IOException e) {
               e.printStackTrace();
//This is code for communication with the process after it's started
   output.writeBytes(id);
   String t = null;
   while( (t = output.readLine() ) != null)
          System.out.println(t);
   String line = null;
   ret[0] = output.readLine();
   while( ( (line = output.readLine()) != null) && (!line.startsWith("[")))
       ret[1] += line;
   ret[2] += error.readLine();
   while( (line = error.readLine()) != null)
     ret[3] += line;

You either have to do read and write in two different threads.
Or if you can modify your external program you can implement some protole which tels the reader that message is orver (Ex:- "OVER" word used when using halfduplex communication devicies)
Or you should meke your program smart enough to understand the external program so it can decide whether there are more data to be read by looking at the data which is already read.
Or you can use the method available() in the input stream which return the number of bytes that can be read without blocking. But this can be problamatic since when you call it it mighe return 0 when there are no data at the your end of the pipe but the external program is actually writing to the pipe

Image Reading Writing from TIFF format

I have tiff files which contain average 30 images, i want to split it in batch. batch can be of 5 images or 10 images, it can be varry.
Pls Help....

Java ImageIO can do this for you. You'll need to do a bit of reading about it, there is plenty to digest on this forum and in various parts of the internet.
If you have any further, more specific questions, please ask.

Problem on reading and writing from from a *.txt file

I get Problem on reading and writing from from a *.txt file. The following is the read() method...
The software said the DataInputStream is depreciated. Can anyone help me please?
public void read()

Thank you for your reply. I have made some change. However, there is an incompetable type found error.
in = new BufferedReader(new InputStreamReader(in));The following are all of the code.

READING AND WRITING FROM A FILE(WRITTEN IN ANOTHER LANGUAGE)

# Comment
INTEGER Declares integer type variable
STRING Declares string type variable
LET Assigns a variable
CALCULATE Performs an arithmetic calculation
PRINT Writes data to the console
PRINTLN As print, but followed by a new line
END Terminates the program
Each line of the program must begin with one of these words, and the language should not be case sensitive.
Tim Brailsford, 2007
G64ICP
COMMENT
Any line beginning with the # character is completely ignored.
Example:
# ignore this line!
INTEGER
The INTEGER reserved word declares an Integer variable, and assigns a default value of 0 to it.
Example:
INTEGER myInt
This example is equivalent to the Java statment "int myInt=0;"
STRING
The STRING reserved word declares a String variable, and assigns an empty string to it.
Example:
STRING myString
This is equivalent to the Java statement "String myString;"
LET
This assigns values to variables (either integers, or strings enclosed
in double quotes).
Examples:
LET myInt=42
LET myString="Hello World!"
CALCULATE
This performs numeric calculations upon values or variables, and assigns the result to a variable (which must have
been declared earlier). Four operators are supported: + *
and / (for addition, subtraction multiplication and
integer division respectively).
Examples:
CALCULATE myInt=2*2
CALCULATE myInt=myInt+24
CALCULATE myInt=intA/intB
PRINT and PRINTLN
These words both print to the console the
only difference being that PRINTLN appends a new line (as does
System.out.println in Java). These can print either text provided as an argument, or variables (string or integer).
Examples:
PRINTLN "Hello World!"
PRINT myString
PRINTLN myInt
END
This terminates the program, and prints a message to that effect.
TPL Example
To the left is an example TPL input file , to
calculate the factorial of 5. This should produce
an output similar to that shown overleaf (except
that calculates the factorial of 10).
# A TPL Program to calculate the factorial of 5
INTEGER myInt
INTEGER factorial
STRING myString
LET mystring="Factorial Program"
LET myInt=5
CALCULATE factorial=myInt*4
CALCULATE factorial=factorial*3
CALCULATE factorial=factorial*2
Tim Brailsford, 2007
G64ICP
PRINTLN mystring
PRINTLN
PRINT "The factorial of "
PRINT myInt
PRINT " is "
PRINTLN factorial

Document your code by writing instructions explaining how to run it, listing all of the files you have submitted,
and specifying any limitations (eg you might want to say what platforms you would expect it to run on, and what
platforms you have tested it on). This document should be written as a plain text file (ie ASCII � MS Word binary
files are not acceptable) � and this file should be called README.TXT. This file should constitute the user
manual of your program, and should explain exactly how to use your program.
The README file should be the user manual for your language as implemented.

ps when i use tail in unix to read the end of the xml file it doesnt work correctly as i cannot specify the number of lines to show, it shows all of the file as thought it is not split into lines or contains new line chars or anything, it is stored as one long stream, is this correct??

hi, i am still having lo luck with reading the xml data back into memory, as i have said before, the netbeans profiler is telling me it is a char[] that is using 50% of the memory but i cannot see how a char[] is created, my code doesn't so it must be the xml code...plz help

Open Data Set Error while trying to read file from non SAP server

Hi all,
is it possible to read data from non-SAP application Sever?
I'm using OPEN DATASET p_filin FOR INPUT IN LEGACY TEXT MODE CODE PAGE '1504',
Where p_filin is other Windows server.Our applicition server is under Unix.Is it a problem?
I make test to read file from SAP application server and it was ok.So how to call other server?
Thanks!

Hi,
Yes it is possible to read data from a non SAP server through the statement OPEN DATASET.
The important thing to check is that the SAP Server got enough access to the non SAP server so it can perform a reading/writing process depending on your needs.
You should contact your network administrator and BASIS to help you check the permissions. This can be pretty tricky, specially if the servers are in different domains.

Reading/writing to serial port w/ VISA in Labview

I'm writing a Labview program to control and to read data from a Varian vacuum pump controller. It is connected to the serial port in my computer, and I have been trying to open a VISA session to communicate with the instrument. So far, however, the computer cannot see the instrument--I get the same error messages reading and writing to the instrument as I do to an empty serial port. Does anyone have any suggestions on what the problem might be? Thank you.

There are a lot of possiblities. Is the cable correct? You probably need a crossover cable (TX and RX) swapped. You also need to check and make sure the serial ports on both ends are set the same (i.e. baud rate, handshaking, stop bits, etc.). Make sure that the port is enabled. I've seen people try to use a comm port only to find that a modem card installation caused the port to be disabled. You could also try using hyperterminal to talk to the instrument. If you can communicate there, you can eliminate any hardware problem.

Cannot see optical drive or read files from superdrive

This is my first ever posting so I apologize if I’m giving too much info.
A couple years ago I installed a Pioneer DVD-RW DVR 107D in the top bay of my G4 (mirrored doors) and put the combo drive (Philips CDD5105) in the bottom bay. Back then I was running OS 9. All worked well, and continued to after I decided to start using OS X. I continued updating all the way up to 10.4.8 (I have avoided updating to 10.4.9 since it caused issues on our IBook). About a year ago the combo drive would come and go (in the system profiler) but the super drive was still working fine. Over the past year strange things began happening. If I would insert a kids games CD it would cause a kernel panic. So I simply used our Ibook to let my daughter play reader rabbit. For about the past 6 months the combo drive has not been recognized in system profiler. But other than the kids cds the super drive seemed to be working well reading & writing both CDs & DVDs. Then it began to error out burning CDs saying they could not be verified but the CDs were turning out ok it was burning DVDs without a problem. Within the last couple weeks it stopped recognizing files correctly. If it is an image or ai document it would say the files could not be opened and it would also not open installers of any kind. I finally decided to try to get it fixed. Last weekend I ran Tech tool & optimized the hard drives and low and behold it was fixed. Combo drive was back & working, Super drive was working correctly & the kids CDs did not cause problems either. This lasted for about 4 days of very infrequent use and all the problems were back. Then yesterday after being off for a couple days I started it up and all was ok again. So I left it on over night planning to make a disk image of it today. At this point I had a theory that my set up might be causing the problem. Since I had been running OS X it was installed and running on a second hard drive I had installed connected to a slave bus while OS 9 was still on the original hard drive connected to the master bus. So I cleaned off the main hard drive and thought since it was working correctly I could transfer the system & apps to the other hard drive and save the working disk image. But of coarse in the middle of transferring files around the combo drive vanished again and the super drive won’t read files correctly. So I decided to reinstall from my OS 10.4 DVD on the main hard drive and reinstall all my apps. But I can’t get it to read or boot up from the DVD. I tried running Tech Tool again with no luck.
Could this be as simple as a bad preference or something?
Here are the machine specs
Machine Name: Power Mac G4
Machine Model: PowerMac3,6
CPU Type: PowerPC G4 (2.1)
Number Of CPUs: 2
CPU Speed: 867 MHz
L2 Cache (per CPU): 256 KB
L3 Cache (per CPU): 1 MB
Memory: 1.75 GB
Bus Speed: 133 MHz
Boot ROM Version: 4.4.8f2
PowerPC G4 dual 867 Mac OS X (10.4.8)

The only thing that seems strange about it being the drives is that whenever the combo drive disappears from the menu the super drive will simultaneously not read files correctly and cause kernel panics etc. And when the combo drive can be seen both drives work with no problems. Would that system still point to failing hardware? It just seems that since it's either both or neither that something that effects them both would be the culprit. Since I posted I was able to reload tiger & after the restart the problem returned. Then another restart it was fine all day. To your point replacement drives are reasonably priced & easy to install so I probably should just get one & try it.
Thanks for your advise

I am unfamiliar with the recovery manager. Here are two guesses.
-- Is system profiler around? It will tell you your serial number.
Report system info
Blue apple > about this Mac
click on more info
click on hardware
You serial number will appear after Boot ROM. Do not copy hear.
--- The newer machines include a recovery partition. Perhaps looking around recovery manager would reveal something.
