Unicode migration via socket

Dear all,
I am converting an ECC system to unicode using the socket option. Shortly after the communication between the two server has been established and 2 jobs has been completed I can not see any procedure. And in sapinst gui I can read "RESPONSE: BUSY". Find below the export and import monitor logs.
Any idea what could cause the problem? Thanks in advance for any info provided.
This is short cut/past from export_monitor.log:

Hi,
R3load option using Sockets requires a very stable network. Any glitch in the network could lead to problems like communication server busy etc. So ensure that you have stable communication between your source and target system and the dump location and restart the migration process.
Additionally please check whether you have updated R3load executable for your SAP kernel release.
Info:
R3load socket option:
You can use the socket option, if your R3load has at least patch level 73 (compile date: 12.01.2008)

R/3 Export & Import during Unicod Conversion via SOCKET Method

Hi
We are in the process of upgrading our R/3 Enterprise to ECC 6.0. The size of the database is around 4 TeraBytes.
Can somebody help us with necessary documentation/ othe rinputs to handle R/3 Export & Import using SOCKET method? FYI we referred the SAP given doucments on the same. Any particular DOs & DO NOTs would be highly appreciated.
Thank You
Sai

Hi Rahul
regarding your 'Unicode doubt"' some ideas:
1) The Upgrade Master Guide SAP ERP 6.0 and the Master Guide SAP ERP 6.0 include introductory information. Among other, these guides reference the SAP Service Marketplace-location http://service.sap.com/unicode@sap.
2) In Unicode@SAP can you find several (content-mighty) FAQs
Conclusion from the FAQ: First of all your strategy needs to follow your busienss model (which we can not see from here):
Example. The "Upgrade to mySAP ERP 2005"-FAQ includes interesting remarks in section "DO CUSTOMERS NEED TO CONVERT TO A UNICODE-COMPLIANT ENVIRONMENT?"
"...The Unicode conversion depends on the customer situation....
... - If your organization runs a single code page system prior to the upgrade to mySAP ERP 2005, then the use of Unicode is not mandatory. ..... However, using Unicode is recommended if the system is deployed globally to facilitate interfaces and connections.
- If your organization uses Multiple Display Multiple Processing (MDMP) .... the use of Unicode is mandatory for the mySAP ERP 2005 upgrade....."
In the Technical Unicode FAQ you read under "What are the advantages of Unicode ...", that "Proper usage of JAVA is only possible with Unicode systems (for example, ESS/MSS or interfaces to Enterprise Portal). ....
=> Depending on the fact if your systems support global processes, or depending on your use of Java Applications, your strategy might need to look different
3) In particular in view of your 3rd option, I recommend you to take a look into these FAQs, if not already done.
Remark: mySAP ERP 2005 is the former name of the application, which is named SAP ERP 6.0, now

Unicode Migration on MaxDB - create indices - R3Load

Hi Folks!
Currently we are performing an Unicode Migration (CU&UC) ECC 6.0 on Windows 2003 / MaxDB 7.6.
We are using migration monitor for parallel export and import with 12 R3Load processes on each side.
Export is finished successfully but import is taking very long for index creation.
There is one strange behaviour:
import_state.propeties -> all packages are marked with "+" except one:
S006=?
When I take a look at S006.STR there is only one table (S006) and two indices (S006ADQ, S006Z00) listed.
Taking a look at Import installDir:
S006.TSK shows:
T S006 C ok
P S006~0 C ok
D S006 I ok
I S006~ADQ C ok
S006.TSK.bck shows:
T S006 C xeq
P S006~0 C xeq
D S006 I xeq
I S006~ADQ C xeq
I S006~Z00 C xeq
S006.log shows:
(DB) INFO: S006 created#20081203192452
(DB) INFO: Savepoint on database executed#20081203192453
(DB) INFO: S006~0 created#20081203192453
(DB) INFO: Savepoint on database executed#20081203193256
(IMP) INFO: import of S006 completed (4858941 rows) #20081203193256
(DB) INFO: S006~ADQ created#20081203193351
(DB) INFO: S006~ADQ created#20081203193351

(DB) INFO: COSP~2 created#20081203193920
(DB) INFO: RESB~M created#20081203194032
(and many many more)
There is only one R3Load running at the moment (others are finished)
I am not a MaxDB pro but what it looks like (to me):
All packages have been imported successfully and import_monitor is creating MaxDB indices using just one R3Load for creation and S006.log to log all the (secondary) indices which have been created.
This procedure is taking very long (more than 12 hours now). Is this a normal behaviour or is there any way to speed up index creation after data has been imported?
If I recall correctly, using Oracle each R3Load creates table, imports data and creates indices right afterwards.
On MaxDB it looks like index creation is performed with just one R3Load after all tables have been imported.
I have read a note about MaxDB parallel index creation which might be the reason for this behaviour (only one index creation at a time using parallel server tasks). But taking a look at the import runtime this doesn't seem to be efficient.
Any ideas or suggestions?
Thanks a lot.
/cheers

You´re right with what you see/saw. That behaviour is caused by the task how MaxDB created indexes. It uses "server tasks" to get all the blocks/pages from disk and create the index. If more than one index creation would run in parallel, it would take much more time because they would "fight" for the max. number of server tasks.
You can see what the database is doing by executing
x_cons <SID> sh ac 1
Unfortunately there is no way of changing that behaviour....

Gettin data from SAP R/3 4.7 unicode sys to SAP ERP non-unicode sys via RFC

We are trying to get data from SAP R/3 4.7 unicode sys to SAP ERP non-unicode sys via RFC. We are reading field from the database via FM and this field got converted by SAP standard Method (CL_ABAP_CONTAINER_UTILITIES=>fill_CONTAINER_C) from structure. When reading this field from ERP sys and converted back to structure using SAP standard Method the value is un-accurate, and different(blank) giving values.
How, if the data originally was a char or numeric it works fine, but not for decimal.
best regards,
Abu-Qaht

I have a range fields with different type of ranges, am saving these to the database by converting them to a string via the same method. I got the same problem so I tried to convert the string to xstring using function SCMS_STRING_TO_XSTRING, before send it to the other system, but the function raised an exception: CX_SY_CONVERSION_CODEPAGE

I need to send a message via socket from a C program to a Java program

Hi,
I need to send a message via socket from a C program to a Java program. The message has three data: a long, an integer and a string.
How can I put those three fields in a array of bytes in C? How can I extract those same three fields from an array of bytes in java?
Thanks a lot!

A few options:

Using sockets directly

Whats the difference between sending messages via socket and MQs?

Whats the difference between sending messages via socket and MQs?

Soph wrote:
Whats the difference between sending messages via socket and MQs?With JMS (and the like) your application uses a socket to connect to a central server called a "*Message Broker*". Over this connection it can send or receive messages.
A Message Broker is somewhat analogous to a database server. Multiple clients connect to it to exchange messages. As with a database a client first establishes a connection, then requests specific facilities like subscriptions.
It creates a strong decoupling between sender and receiver and handles stuff like allowing multiple receivers for the same message, queuing of messages for applications not currently running and so on.
(And don't worry, you can get perfectly good message brokers for free such as openMQ and activeMQ.)

Can UCCHECK be performed on already UNICODE migrated system during ECC upgr

Hi there,
Can UCCHECK be performed on already UNICODE migrated system during ECC upgrade?
If NO, why? What is the technical reason?
Prakash

Hi,
first unicode means
Unicode is a 16-bit code to represent universal character set, which is used to facilitate a better exchange of data between different systems.
for uncheck
The transaction UCCHECK is used to find Unicode related issues. You can use transaction UCCHECK to examine a Unicode program set for syntax errors without having to set the program attribute "Unicode checks active" for every individual program. From the list of Unicode syntax errors, you can go directly to the affected programs and remove the errors. It is also possible to automatically create transport requests and set the Unicode program attribute for a program set.
why you are checking second time.

Madhu

Can i seperate ABAP conversion from the Unicode Migration Process ?

Hi all,
I don't have detailed technical information about ABAP programs and i need to deliver a project (unicode migration project) which needs some time arrangements. Because of that, we're trying to find out other ways to decrease the total time.
As SAP guide says; before the migration, we must convert the ABAP programs. When we check them, only ABAP programs that our developers wrote, need to be converted. So the question is; is it possible to seperate these steps ? I mean, go on the unicode migration without converting ABAP programs and meanwhile, change ABAP programs in another SAP system (similar to the live one). With this process, save some time and then import the converted ABAP programs to the migrated unicode system. Is it possible ?
Any help will be appreciated, thanks in advance.

I currently am using Postbox during the trial period because the frustration of trying to solve this ridiculous problem I posted about above was too much. Unlike most people, I won't rant and rave about OS X's decline after Lion and Mountain Lion as I never had major issues after upgrading to either of them. It's just beyond belief that the magnitude of this last problem being able to break an app within something that is just supposed to "work" that is beyond me.
Anyway, I was wondering if anyone who uses Postbox might be able to offer a suggestion or two about how to import mailboxes from a Time Machine backup as I would still like to have access to those folders which were "On My Mac" with all of the archived messages which were contained within each of them? I know that you can import from Apple Mail, but that's only if it is currently set up they way you want it to be. And as I no longer have those settings because I can't restore to the point before I deleted all the accounts, etc. from Mail in my frustration -- I'm sure I can't just point Postbox to some plist file to have it mimic my old Mail setup.
Anyone?

Product Instance has pre-9.0 licenses installed. These can be migrated via the License Planning page.

I am looking at upgrading my UC cluster from 9.1 to 10.5 and when looking at ELM I see the following message at the bottom of the Inventory > Product Instances page:
Product Instance has pre-9.0 licenses installed. These can be migrated via the License Planning page.
I have searched around but I cannot find any info on this message or how i am supposed to migrate the licenses.
Has anyone seen this before? Any suggests?
Thanks in advance

You would only get that if you upgraded to 9.1 and didn't upgrade the licenses through ELM. I would consult with cisco tac (licensing) or your cisco partner to validate you're fully in compliance and that nothing was missed when you upgraded to 9.
Check out this tech note on license migration from 8.x to 9.x to verify you do this before going to 10.5.
http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-callmanager/116231-technote-cucm-00.html
It basically involves going to the license planning page, performing the 'license upgrade', select the product instance and counts then send that all over to licensing @ cisco.com with a license request.
Good luck.

Receiving Image via socket and creating via byte[]...

Hi Folks...
I�m trying to send a WebCam SnapShot to my Midlet running in a PDA via socket..
The method used to send the Image is:
BufferedImage img = toBufferedImage( getScreenShot( getFrameBuffer() ) );
          byte[] buf = convertImage( toBufferedImage( img ) );
          BASE64Encoder enc64 = new BASE64Encoder();
          enc64.encode(buf);
          try {
               out.writeUTF("IMAGEM");
               out.writeInt( buf.length );
               out.write( buf );
          } catch (IOException e) {
               e.printStackTrace();
          }So this code get a snapShot from the webCam and returns a BufferedImage. This BufferedImage is converted to a byte[], and later this byte[] is encoded in Base64 format with BASE64Encoder.
In the next step the buffer is sent to the client, the server send the message "IMAGEM", in the sequence the size off the byte[] and then the byte[].
The code that receive the Image byte[]...
private void receiveImageAction(){
          byte[] buf;
          try {
               buf = new byte[ in.readInt() ];
               in.read(buf);
               Image img = Image.createImage( buf, 0 , buf.length );
               viewForm.setMsg("Image created");
               viewForm.setImageView(img);
          } catch (IOException e) {
               viewForm.setMsg( "" + e.toString() );
          }catch(Exception e){
               viewForm.setMsg( "" + e.toString() );
     }When the connection manager receives a message "IMAGEM" the function receiveImageAction is called.
It receives the size off the byte[] and then receive the array.
When I try to create the image using Image.createImage( byte[], int, int ) the exception IllegalArgumentException is throwed...
The exception doesnt have a message...
What is wrong ?
Is the format off my image sent ?
Is my buffer been encoded correctly by the BASE64Encoder class ?

Will u try with replacing this line
Image img = Image.createImage( buf, 0 , buf.length );with this line
Image img = Image.createImage( buf, 0 , buf.length-1 );

***ANSI connection via socket

Hi
I need help!!
How can i establish an ANSI connection via socket??? because the server dont let me connect with a VT100 connection

The book Core Java 2 from Sun has a good discussion on that.
There is a thread in The Water Cooler titled YAT which is a
discussion of that book. Read through it (there are about 3400+ posts).
They should have it. It would take too long for me to re-search my book.
Do a search on the Java site for ANSI or Character Map, you
will probably find documentation and tutorials on it.
Let me know if you can't find them.

Not able to send euro character ' €' via socket

OS : Solaris - The solaris login profile is set with LC_CTYPE, LC_CTYPE, LC_LANG=ISO-8859-15 and we are able to see this when we run the set command and also locale in solaris.
JRE : 1.6
Application deployed in Weblogic 10.3
I m trying to send a euro character in java via socket, but in the receiving end not able to receive properly. Even I have to tried to set the Charset ( in the java code )
as ISO-8859-15 , but still it didn't work properly. Code snippet for the sample program to display euro symbol
import java.io.UnsupportedEncodingException;
import java.nio.charset.Charset;
public class Euro {
public static String createString( byte[] bytes, String enc )
String CResult = null;
try {
CResult = new String( bytes, enc );
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
return CResult;
// ISO8859-15 is same as ISO8859-1 but with EUR character
public static String createStringISO8859_15( byte[] bytes )
String CResultISO = null;
CResultISO = new String( bytes, Charset.forName("ISO-8859-15" ));
return CResultISO;
public static void main(String[] args) throws Exception {
//String enc = "€";
byte[] iso8859_15 = { (byte) 0xA4 }; // euro sign
//byte[] iso8859_15 = "0xA4".getBytes(); // euro sign
/* String Cresult = Euro.createString (iso8859_15, enc);
System.out.println("createString Result : " + Cresult);*/
String CresultISO = Euro.createStringISO8859_15(iso8859_15);
System.out.println("createStringISO8859_15 Result : " + CresultISO);
When I 'm running the above code in windows it is working fine whereas in Solaris it is not working. The console just displays ?, rather than the actual '€' symbol. Is this a display problem in console of vt100 or porgramming? Kindly suggest. How to make this work in Solaris.

Please repost or edit that mess with {noformat}{noformat} tags and proper indenting so it can actually be read.
And then explain what sockets have to do with the price of fish.

Trouble with USB2 after XP SP1 (coming from VIA Socket A board)

(This is condensed from a thread originally on the VIA Socket A Based board. I was requested by maesus to move it here asI have an Intel board.)
I have a new 845E Max2 motherboard and installed Windows XP.
I have a USB2 problem after installing XP SP1 - yellow question marks in the hardware manager under "Other Hardware"/"USB (Universal Serial Bus)-Controller".
I tried "Uninstalling" the USB controller as was suggested in the (VIA) forum, but it won't let itself be removed.
When I try "Search for new hardware" it shows a message that an error occurred when installing the hardware, and that the hardware is not properly configured (Code 1). It suggests that I re-install the driver. When I select "re-install driver", I just get another error message. It asks me if I have a CD or disk wit drivers, but I can't find anything appropriate on the driver disk I got with the motherboard.
I'm sure USB is enabled because I'm able to operate USB devices using both the standard board rear sockets and those on the extra bar. I have a HP USB Scanner and a PenCam, both of which work OK.
In the Devicew Manager, under "USB", there are three USB controllers and three USB Hubs noted, all designated as operational.
I assume that the "unknown" device which is causing trouble is the on-board USB 2.0 controller which is supposedly supported by MS Win XP SP1. For this reason I can't find a suitable driver to load - maybe there's one in the SP1 somewhere but I have no idea where to start looking for it. (I even tried re-installing the SP1, with no positive results.)
I sent a direct enquiry to MSI's support desk last week but, up to now, have had no response.
Has anyone an idea where I should start looking for a driver? I tried the MSI driver CD I got with my board, but couldn't find anything suitable. Or any other advice how to solve the problem?
Regards Steve

Hi again!
Tried the procedure suggested by the (fairly recent - I think March or April 2002) "Lockergnome" WinXP tip(Sorry I don't have a reference now, but this is my work machine and I don't have Lockergnome archive installed) and it seems to work - at least I no longer have an "unknown" device with yellow question marks in the device manager, and I DO now have an "extended USB 2" device in device manager under "USB", in addition to the 3 standard MoBo USB ports and 3 USB hubs I had up to now.
The trick was that XP's Driver installation routine was saying my USB2 driver data were "invalid". In fact, it was just that certain PCI registry permissions were set to "read-only" for administrators, instead of "full-access". Opening up the permissions with regedit, then re-installing the USB driver seemed to do the trick.
If I still have USB2 problems, I'll post them but I hope I've cured this one. I'll also post the reference to the Lockergnome article when I get home.

Migrating via external hard drive doesn't work

I'm migrating from a Powerbook G4 to an iMac G5. For iTunes, I copied all data onto an external hard drive and connected that to the new iMac. But I can neither import the files via the "add to library"* command in iTunes nor can I simply copy the files onto the hard drive of the new iMac. The error message is always the same: "The attempt to copy onto the volume "Macintosh HD" failed. This medium is neither readable nor writable."* Needless to say, that I don't have any problems with the hard drive except for this one. Why is that so?
*This is the translation of the German command/message - the English version actually might be slightly different.

Maverick,
Assuming that you're using the standard paths on your PB G4:
Just go to your user directory / Music: Copy the complete "iTunes" folder with all its content & all subfolder to your external disk.
On your G5 also go to your user directory / Music: Now replace the "iTunes" folder with the copy on your ext. disk.
Using this procedure all your playlists/playcounts ... will be migrated as well.

Hi!!
The problem is at this line:
System.out.println("Copies "+fileIn.read(buffer)+" bytes");
Just comment out this line of code and see the difference. This line of code causes another "read" statement to be executed, but you are writing only the data read from the first read statement which causes approximately half the file to be send to the server.
