Telnet Read VI and variable length response

I am trying out Internet Toolkit's Telnet VIs.
It seems that the Telnet Read VI defaults to 60 bytes.
I am not sure what is the best way to deal with the situation of a variable length response.
Some responses are 3 lines; others can be 50 lines.

the line seperator is explicitedly <CR><LF> or carriage return and line feed. No other line seperator is automatically supported.

SQL*Loader and "Variable length field was truncated"

Hi,
I'm experiencing this problem using SQL*Loader: Release 8.1.7.0.0
Here is my control file (it's actually split into separate control and data files, but the result is the same)
LOAD DATA
INFILE *
APPEND INTO TABLE test
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
first_id,
second_id,
third_id,
language_code,
display_text VARCHAR(2000)
begindata
2,1,1,"eng","Type of Investment Account"
The TEST table is defined as:
Name Null? Type
FIRST_ID NOT NULL NUMBER(4)
SECOND_ID NOT NULL NUMBER(4)
THIRD_ID NOT NULL NUMBER(4)
LANGUAGE_CODE NOT NULL CHAR(3)
DISPLAY_TEXT VARCHAR2(2000)
QUESTION_BLOB BLOB
The log file displays:
Record 1: Warning on table "USER"."TEST", column DISPLAY_TEXT
Variable length field was truncated.
And the results of the insert are:
FIRST_ID SECOND_ID THIRD_ID LANGUAGE_CODE DISPLAY_TEXT
2 1 1 eng ype of Investment Account"
The language_code field is imported correctly, but display_text keeps the closing delimiter, and loses the first character of the string. In other words, it is interpreting the enclosing double quote and/or the delimiter, and truncating the first two characters.
I've also tried the following:
LOAD DATA
INFILE *
APPEND INTO TABLE test
FIELDS TERMINATED BY '|'
first_id,
second_id,
third_id,
language_code,
display_text VARCHAR(2000)
begindata
2|1|1|eng|Type of Investment Account
In this case, display_text is imported as:
pe of Investment Account
In the log file, I get this table which seems odd as well - why is the display_text column shown as having length 2002 when I explicitly set it to 2000?
Column Name Position Len Term Encl Datatype
FIRST_ID FIRST * | O(") CHARACTER
SECOND_ID NEXT * | O(") CHARACTER
THIRD_ID NEXT * | O(") CHARACTER
LANGUAGE_CODE NEXT 3 | O(") CHARACTER
DISPLAY_TEXT NEXT 2002 VARCHAR
Am I missing something totally obvious in my control and data files? I've played with various combinations of delimiters (commas vs '|'), trailing nullcols, optional enclosed etc.
Any help would be greatly appreciated!

Use CHAR instead aof VARCHAR
LOAD DATA
INFILE *
APPEND INTO TABLE test
FIELDS TERMINATED BY ','
OPTIONALLY ENCLOSED BY '"'
first_id,
second_id,
third_id,
language_code,
display_text CHAR(2000)
)From the docu:
A VARCHAR field is a length-value datatype.
It consists of a binary length subfield followed by a character string of the specified length.

Variable Length Files and ABAP

I have a comma delimited file that is of a variable length.
The first 5 fields are fixed, but then I have a counter field and then 2 fields that repeat for each counter.
So if the counter field was 3, Id have 6 additional fields, but if the counter was 5, Id have 10 additional fields.
The goal is to end up with 3 records (since the counter was 3) with the 5 fixed fields then the 2 fields respectively.
Such as if it looks like this:
Abc,abc,abc,abc,abc,003,1a,1b,2a,2b,3a,3c
DCE,abc,abc,abc,abc,005,1a,1b,2a,2b,3a,3c,4a,4b,5a,5b
I need it to look like this or at least be able to read it similar to this.
Abc,abc,abc,abc,abc,003,1a,1b
Abc,abc,abc,abc,abc,003,2a,2b,
Abc,abc,abc,abc,abc,003,3a,3c

How to save blob data (variable length string) in a customized table?

Dear Friends
I have written a very simple program to update table with 2 fields which
looks as follows.
========================================================
Table name ZTESTBLOBDATA
Field         Key          Init    Data Element   Data Type Length
ID          Checked                 ZID                 NUMC        2
BLOB                                   ZBLOB           STRING       0
=========================================================
FOllowing is the sample program that I have written (Transaction SE38).
=========================================================
REPORT ZTESTBLOBPROG
TABLES: ZTESTBLOBDATA
data : itab like ZTESTBLOPDATA occurs 1 with header line.
select * from ztestblobdata into table itab.
ztestblobdata-id =   sy-dbcnt +1.
ztestblobdata -blob = 'abcdefghijklmnopqrstuvwxyz.'.
insert ztestblobdata.
=========================================================
When I try to save and activate the program, I get the following
error message
'ztestblopdata' must be a flat structure. You cannot use internal
tables, strings, references, or structures as components.
==========================================================
Using the data type STRING is a must since it is a variable length
data which varies from few characters to few gig.
How can go around this problem.
Any feedback will be highly appreciated.
PS. I have checked old postings on SDN, spoken to my ABAP contacts and also couple of instructors from SAP when I took XI courses but didn't get a satisfactory answers.
Edited by: Ram Prasad on Oct 15, 2008 12:28 PM

Thanks a lot for the response.
The string that we are getting is from another application via netweaver XI integration and is being sent as a string which has to be saved in an SAP table. I am not sure if IDOC option will suit our needs, but will definitely read more about it.
If there is any other suggestion of feedback I would appreciate it a lot.;

Data plug-in for binary data with byte streams of variable length

Hi there,
I would like to write a data plug-in to read binary data from file and I'm using DIAdem 10.1.
Each data set in my file consists of binary data with a fixed structure (readable by using direct access channels) and of a byte stream of variable length. The variable length of each byte stream is coded in the fixed data part.
Can anyone tell me how my data plug-in must look like to read such kind of data files?
Many thanks in advance!
Kind regards,
Stefan

Hi Brad,
thank you for the very quick response!
I forgot to mention, that the data in the byte stream can actually be ignored, it is no data to be evaluated in DIAdem (it is picture data and the picture size varies from data set to data set).
So basically, of each data set I would like to read the fixed-structure data (which is the first part of the data set) and discard the variable byte stream (last part of the data set).
Here is a logical (example) layout of my binary data file:
| fixedSize-Value1 | fixedSize-Value2 | fixedSize-Value3 (=length of byte stream) | XXXXXXXXXXXXX (byte stream)
| fixedSize-Value1 | fixedSize-Value2 | fixedSize-Value3 (=length of byte stream) | XXXXXX (byte stream)
| fixedSize-Value1 | fixedSize-Value2 | fixedSize-Value3 (=length of byte stream) | XXXXXXXXXXXXXXXXXXXX (byte stream)
What I would like to show in DIAdem is only fixedSize-Value1 and fixedSize-Value2.
´
If I understood right, would it be possible to set the BlockLength of each data set by assigning Block.BlockLength = fixedSize-Value3 and to use Direct Access Channels for reading fixedSize-Value1 and fixedSize-Value2 ?
Thank you!
Kind regards,
Stefan

Changing a variables length for text input in Captivate 6

I am using eLearning CS6 (non-subscription I believe, but no one at my office can confirm) and use a machine where all software is deployed via push from IT. The ability to check for updates has been removed from me.
I need to be able to have users enter data into the course and have it both be forwarded on to our database AND appear in later segments of the course.
I recall being able to update the TEB variable length in previous versions but can not find the option anywhere in CS6. or perhaps I'm imaging it.
I am running version 6.0.1.240 and there is no Format option in my TEB properties. I do not see alignment options, and instead see Characters as a menu above the Shadow & Reflection option.
I do know where to set the value in a text caption box. However, I seem to be limited to entering a single variable in the caption field in order for this to be option. However, there are times where we'd rather have multiple variables strung together on a single line, or a word or two of static text appearing before or after the variable.
If I want to string the user entered data from multiple variables into a single caption box there appears to be no way to change the variable's character length from 15 to a higher value.
Does anyone know of another way to work around this other than through the use of multiple caption boxes?
I've been driving myself a bit batty trying to think of a way around the 1 caption 1 variable limit...
Thanks.
Note: Please don't advise me to upgrade. I've already been told the office will not pay for an update to the software so quickly on the heels of our upgrade from CS 5.5 to CS6 (happened within a 6 month span).

15 characters is the default when you insert the variable into a text caption. But you can set this to anything from 1 to about 250...as long as you use the Insert Variable icon in the Properties tab > Format accordion to insert the variable. Look for the field in the dialog that allows you to specify the variable's display length.

Problem in sending a variable length string

Hello friends,
I have created a scenario as follows.
Our
Application ==>(SOAP) ==> XI ==> (RFC) ==> SAP TABLE.
I am sending a record with one of the fields of the type 'VARILRAW'
When I send this, it is sending me a response that it was inserted in the table succesfully, But when I try to retrieve, all fields get returned correctly, but not this variable length field. This sends me back a huge string of letter 'A's.
Here is what I see on SXMB_MONI
The following shows that for insertion, the proper data is coming in XML format.

File Sender, Content Conversion - how to define variable length last field?

XI 3.0 SP17
With a File Sender communication channel, that uses Content Conversion - how do I define a 'variable length' last field?
The scenario - the input file has four fields, of which the first three are a known fixed length, and the last (fourth, trailing) field is variable in length.
Using a Message Protocol of 'File Content Conversion', how do I define that last variable length field (field name 'WOData' below) in the Content Conversion Parameters section?
My current parameters are:
Recordset Structure - Row,*
ignoreRecordsetName - true
Row.fieldFixedLengths - 1,12,5,99999
Row.fieldNames - WOType,WONum,WOLine,WOData
I've tried the following for 'Row.fieldFixedLengths' to no avail -
'1,12,5,*'
'1,12,5,0'
'1,12,5,'
'1,12,5'
The last two were grasping at straws )
The only thing I've got to work is specifying a 'large' value for the final field (99999 above).
In addition, does anyone know if specifying a large value (e.g. 99999) for the final trailing field will give rise to performance issues when the file is being processed?
In the help for "Converting File Content in a Sender Adapter", it states -
<Begin Quote>
NameA.fieldFixedLengths
If you make a specification here, the system expects a character string that contains the lengths of the structure columns as arguments separated by commas.
If you also specify a separator for the columns, you must not add its length to the length of the columns.
This entry is mandatory if you have not made an entry for NameA.fieldSeparator.
<End Quote>
http://help.sap.com/saphelp_nw04/helpdata/en/2c/181077dd7d6b4ea6a8029b20bf7e55/content.htm

<< note that fieldFixedLengths will not take any wildcard entries like *. So in these case it is ideal to provide a maximum char length. But note that while the file is being created that many spaces will be created in your file !!! >>
Hi Shabarish,
Yes, no wildcard is the conclusion I came to, hence my maximum )
The message size did not increase by any 'blank padding'. When I look in [Message Display Tool (Detail Display)] 'Audit Log for Message: X' -

2006-10-17 18:22:42 Success Message successfully put into the queue.
2006-10-17 18:22:42 Success The application sent the message asynchronously using connection AFW. Returning to application.
The input flat file in non-XML format was 92,132 bytes and the message payload into XI was 103,290 bytes.
My understanding is that trailing spaces are stripped from XML nodes.

I need to update specific records(of variable lengths) in a file. I can get the correct record but when I update it(add or change info), it overwrites part of the record following it. I am using labview 6.0. I need to be able to insert information into the middle of a file without disturbing the data before and after

It's hard to give more specifics without more detail, but in general you're going to need to read in the entire file, split it into three pieces (everything before the record of interest, the record itself, and everything after the record of interest), modify the record, reassemble the three pieces in proper order, and write the whole thing back to the file.Of course if the file is very large you might not want to actually implement it this way, but conceptually at least, this is what you are looking at.If this file some sort of proprietary format?Mike...PS: this type of issue is why I really like databases...

How to deal with variable length data struct in C/JNI

I have another JNI related question. How do you handle variable length
data structures in Java and pointer to a pointer?
Basically, I have a backend in C which has records but we don't know
how many. The API looks like
typedef struct rec_list_s {
int rec_list_cnt;
rec_list_data_t rec_list_data[1];
} rec_list_t;
int rec_list_show(void handle, rec_list_t *list_ptr);
/* Code snippet for rec_list_show */
int rec_list_show(void handle, rec_list_t *list_ptr)
rec_list_t *ptr;
sz = sizeof (rec_list_t) +
((record_count - 1) * sizeof (rec_list_data_t));
ptr = malloc(sz);
/* fill the data */
*list_ptr = ptr;
return (0);
So I need to wrap rec_list_show() in JNI call so I can have Java call
it. How do i pass a pointer to a pointer from Java? I tried in the
native C code for JNI to return the pointer to pointer as a result
and store in a member in the Java class rec_list_t and then I pass
that to JNI call for rec_list_show. The C backend code was fine
since it got the pointer to pointer but Java become unhappy when
the object it was referencing changed memory location (I suspect
the garbage collection becomes unhappy).
So what would be a good way to deal with this kind of code?
Thanks,
Sunay
Edited by: st9 on Aug 30, 2010 5:47 PM

I did not imply that you don't know C but you are implying that I don't understand C. Perhaps
google Sunay Tripathi and click I am feeling lucky so that we don't get into teaching C
discussions :) On the other hand, I am definitely looking for someone to teach me Java
otherwise I wouldn't be asking.
Anyway, let me explain again. The sample function rec_list_show() runs on the backend. It
is a different process with a different VM space. It of course knows the size of the array
and what to fill in. As a caller to that API (which is a separate process), I don't know
what that size is but I need to get the size and corresponding data in one shot because
the backend locks the table when its providing me the info to make sure its synchronous.
Now I (the Java process) needs to get that count and data in one shot. Since the C library
underneath me (wrapped around my JNI interface) has private IPC mechanism to copy
the contiguous memory from the backend into my memory space, all I need is to provide
a pointer to a pointer which gets filled in by backend and is available to my process. So
my equivalent C frontend just passes a pointer to a pointer and casts the return value in
rec_list_t. The rec_list_cnt tells it how many members it got. The first member is part of
the struct itself but then following members are right after.
Another way to help you understand this is with this code snippet from front end C program
rec_list_t     *ptr, *save_ptr;
rec_list_data_t *data_ptr;
int          cnt;
save_ptr = ptr = malloc(sizeof(rec_list_t));
rec_list_show(handle, &ptr);
assert(save_ptr != ptr);
cnt = ptr->rec_list_cnt;
for (i = 0; i < cnt; i++) {
     data_ptr = &ptr->rec_list_data;
Notice the assert(). Also notice the for loop. How do I expect to walk more that one
member when rec_list_data is a fixed size array of one member?typedef struct rec_list_s {
     int               rec_list_cnt;
     rec_list_data_t          rec_list_data[1];
} rec_list_t;
Anyway, I do understand that Java will not allow me to get a reference to a long and
how Java memory management works. But the JNI native implementation is C
and I was wondering if people have managed to do some tricks there between C
and Java.

"4000 bytes is the ultimate maximum. you can say 4000 *characters* , but it'll always be limited to 4000 *bytes* . "

"The maximum length of the column is determined by the national character set definition. Width specifications of character data type NVARCHAR2 refer to the number of characters. The maximum column size allowed is 4000 bytes."

By the way, you're treating your numbers as STRINGS, remove the quotes around your zero's.

Variable length in substring

i am trying unsuccessfully to write a udf, as suddenly the fixed length field i was using a substring on has changed to a variable length field...
i need to pass the field into a UDF and then pass out the last two characters for one field...
and the last 5 for another field.
once i have the UDF working for one, i can amend it for the other...
i am probably a million miles away from the solution... but this is where i am so far...
can someone guide me as to how i can pass the variable length into the substring parameter??
String str = var1;
int length = str.length();
output(var1.substring(length -2))

just one line:
return var1.substring(var1.length()-2);
What should "output" do in your example?

Variable length field exceeds maximum length for VARRAW in SQLLOADER

Hi All,
I am trying to load some signature ascii data from load file. so i wrote the code like below in my controal file to load that to database. For SIGN_IMAGE in oracle db it was mentioned as RAW(2000). The below is worked fine when i tried in window and oracle 8i environment.
SIG_TYPE POSITION(23:23) CHAR,
SIGN_IMAGE POSITION(24:1977) VARRAW(2000)
NULLIF SIGN_IMAGE=BLANKS,
SIGN_IMAGE1 POSITION(1978:3930) VARRAW(2000)
NULLIF SIGN_IMAGE1=BLANKS
But when i ported the same thing to solaris and oracle 10g environment. The below code is giving error when SQL Loder loading.
The error is like : Variable length field exceeds maximum length.
But here i am giving a lenght of 1954 only with including 2 bytes length of the string.
Could any one tell me what is exactly the problem? i am not able sort out the issue.
Thanks,
Shashi
