Issues storing binary values

Hi,
I am desperately trying to store userCertificate or cACertificate attributes on an OpenLDAP server. I always end up with following exception:
javax.naming.directory.InvalidAttributeValueException: [LDAP: error code 21 - cACertificate;binary: value #0 invalid per syntax]; remaining name 'cn=1234,�'
The code I am using looks like this:
Attributes attrs = new BasicAttributes(true);
Attribute objclass = new BasicAttribute("objectclass");
objclass.add("top");
objclass.add("applicationProcess");
objclass.add("pkiCA");
attrs.put(objclass);
byte[] certBuf = new byte[] {1,2,3,4,5};
BasicAttribute cert = new BasicAttribute("cACertificate;binary", certBuf);
attrs.put(cert);
Context result = _ctx.createSubcontext("cn=1234,�I assume I need the �;binary� option, as I get following exception if I don�t use it:
javax.naming.directory.InvalidAttributeIdentifierException: [LDAP: error code 17 - cACertificate: requires ;binary transfer]; remaining name 'cn=234,�
The very strange thing is that I have tried to add a jpegPhoto (same dummy-data as the certificate )to the LDAP server and this works fine - without the �;binary� option:
BasicAttribute photo = new BasicAttribute("jpegPhoto", photoBuf);I don�t think that it is a matter of the JRE as I have tried version 1.4, 1.5 and 1.6. I am also not sure if it is OpenLDAPs fault because it is possible to add those Attributes by using a LDAP client (in my case LDAPStudio).
Does anybody know this issue?
Thanks for any help,
Phil

caCertificate has a well known syntax defined in X.509.
OpenLDAP does have support for these X.509 syntaxes and will verify that the certificate you are adding to the server is valid.
Clearly certBuf = new byte[] {1,2,3,4,5}; is not a valid certificate.

Doubt on calculating Hexadecimal and binary values

Please give me some tips to find the hexadecimal and binary values of negative numbers for eg:-
The hexadecimal value of -1 is 0xffffffff. Here I don't know how the corresponding hex value is calculated.
I calculate the hex value of numbers in this way. For eg: to get the hex value 11
1*16^1 + 1*16^0 = 17.
Similar logic to convert binaries to decimal by using the base 10.

It's about 2s complement arithmatic.
Hexidecimal representation is used by people interested in the bit patterns, rather than numerical values as such so integers are treated as unsigned. But when working in decimal we're generally treating the variable as signed. Negative integers are represented by "adding" 2^32 to them so -1 becomes 2^32-1. This is stored as a word where all bits are 1s, which means in hex all nybles are 'F'.

Fixing size of binary value

Hi,
Simple question but having some issues figuring it out. I have a 13-bit binary value. I want to filter out the last bit. How this can be done?
Thanks

Assigning a hex value to a variable and getting binary value of a variable.

I try to develop java programs and I need to do a conversion unicode to EBCDIC and vice versa.
How can I assign hex values to variables to build UTF-EBCDIC and EBCDIC-UTF table and get hex or binary value of data to compare it to value of in the table?
I did a conversion like this with PL/1 before. I do not know how can I do it with Java. Because I am new to Java.
Thank you in advance.

I will run java code in mainframe and java uses
unicode for data in default and mainframe environment
is EBCDIC. So I have to translate the data from
unicode to ebcdic.I said I think String supports EBCDIC encoding...
String ebcdic = new String(ebcdicBytes, "Cp500");

Need to convert a binary value into decimal

Hi i need to convert a binary value which i would be getting as a string object to a decimal value......need code for the same

Assigning a binary value to an integer

Hi, I am trying to assign a binary value in my program to an integer. In some assembly languages you would do the following:
mov a, 00010101b
for binary and for hex:
mov a, 0E2h
In java, you can assign a hex value with:
int a=0x3F;
What should I do to assign a binary value? Is it possible?
Regards... Martin Schmiedel

The static method parseInt in the java.lang.Integer class can be used to convert a String representing a binary number into its decimal integer value. In addition to the string representing the number, you also pass in an integer representing the radix, which for binary would be 2, hex would be 16, etc. So for example:
int x = Integer.parseInt("00010110", 2);
Is that what you're trying to do? Cheers,
Chris

Binary Values unreadable - Database corrupt?

Hi,
I'm experiencing a really weird problem here, I have a table with some varchar columns and two binary columns. What I do now, is to select data from it via Python with the following select statement:
select * from torder where customerid=1624 order by torderid desc
What happens is, that only for this customerid some binary data is missing, they contain an empty string. If I do the select like this:
select * from torder where customerid=1624 order by torderid
It does work, the data is there. With this, it works too:
select * from torder order by torderid desc
So it seems, the combination of "customerid=1624" and "desc" somehow corrupts the results.
What's furthermore interesting is, that when I delete the last inserted row of the result, it works, and if I add a new one, it's broken again.
I could not check if the error is Python-related or not, as I found no way to retrieve/display the binary data in sqlcli, as it displays only something like 0x8002637A6F70652E6931 , but I doubt that this has something to do with Python.
Any clues of how to fix this?
My database version is Kernel 7.6.06 Build 003-121-202-135 | X32/LINUX 7.6.06 Build 003-121-20
2-135
Previously, I had 7.6.03 and updated it to the above version, hoping that this would fix the problem, but it did not.

Ok, first many thanks for your quick reply. I did not answer at first as the problem magically went away. But unfortunately the problem is back today.

The DDL statements look the following, there are no indexes on the table:

<pre>
CREATE TABLE torder (
 torderid INTEGER NOT NULL DEFAULT SERIAL,
 creation_date TIMESTAMP,
 transfer_date TIMESTAMP,
 signed_date TIMESTAMP,

 revocation_date TIMESTAMP,
 done_date TIMESTAMP,
 formdata LONG BYTE NOT NULL,
 trans_function VARCHAR(30) NOT NULL CHECK (trans_function in ('do_bank_transfer', 'do_bank_collection',
 'do_cheque_transfer', 'do_cash', 'do_cashdraw')),
 trans_type VARCHAR(30) NOT NULL CHECK (trans_type in ('national','sepa','international')),

 FOREIGN KEY(customerid) REFERENCES kunde (kundeid),
 FOREIGN KEY(dbuserid) REFERENCES dbuser (dbuserid),
 FOREIGN KEY(torder_periodicid) REFERENCES torder_periodic (torder_periodicid)
</pre>

The insert statements look the following (They are copied out of the SQLAlchemy SQL log), one can see that the binary values are inserted here:

<pre>

All rows are inserted with binary data, so it's never NULL and it's also never set to an empty string ('').

But when reading back the rows, some binary values are an empty string.

The following Python code illustrates the problem:
<pre>
import sapdb.dbapi
def true_false_result(result):
 if result:
 return 'Bug begins'
 else:
 return 'Bug ends'
def check_bincols(bdb, sqlcmd):
 print "----
 print "QUERY: %s" % sqlcmd
 print "----
 bdbc = bdb.cursor()
 bdbe = bdbc.execute(sqlcmd)
 bug_occured = False
 stored_bin_result = False
 while 1:
 row = bdbe.fetchone()
 if row is None:
 break
Now check if the binary data results to an empty string,
This should never happen (= the database bug)
 bin_result = (row[7]() == '')
 if bin_result != stored_bin_result:
 bug_occured = True
 print "Toggle to %s at torderid %s" % (
 true_false_result(bin_result),
 row[0])
 stored_bin_result = bin_result
 if not bug_occured:
 print "No Bug for this query"
 bdbe.close()
 bdbc.close()
#bdb.close()
if __name__ == '__main__':
 bdb = sapdb.dbapi.connect('USER', 'PASS', 'DBNAME', 'LOCALHOST')
First try the original query, which results in a bug
 sqlcmd = 'select * from torder where customerid=1624 order by torderid desc'
 check_bincols(bdb, sqlcmd)
This query normally is bugfree
 sqlcmd = 'select * from torder where customerid=1624 order by torderid'
 check_bincols(bdb, sqlcmd)
This query has a bug, too
 sqlcmd = 'select * from torder order by torderid desc'
 check_bincols(bdb, sqlcmd)
But this one not
 sqlcmd = 'select * from torder order by torderid'
 check_bincols(bdb, sqlcmd)
This triggers the bug, too, which is curious as there's practically no ordering
 sqlcmd = 'select * from torder where customerid=1624 order by customerid desc'
 check_bincols(bdb, sqlcmd)
So, it seems that the bug occurs only when using "DESC" for descending
ordering.
</pre>

The output of this program is:

<pre>
QUERY: select * from torder where customerid=1624 order by torderid desc
Toggle to Bug begins at torderid 1355
Toggle to Bug ends at torderid 582
QUERY: select * from torder where customerid=1624 order by torderid
No Bug for this query
QUERY: select * from torder order by torderid desc
No Bug for this query
QUERY: select * from torder order by torderid
No Bug for this query
QUERY: select * from torder where customerid=1624 order by customerid desc
Toggle to Bug begins at torderid 1355
Toggle to Bug ends at torderid 582
</pre>

So, it can be seen that the problem occurs ONLY when using descending ordering. Moreover it's interesting that the result for "select * from torder order by torderid desc" is sometimes buggy, sometimes not, which seems to be related if someone inserted some more rows or not. What's furthermore interesting is the last query, as there the order is applied to "customerid", which is the very same for every row, so there is no ordering and the bug occurs here, too.

All this happens on my production instance. I have a testing environment, where I imported the very same data set (same database version etc.) and there is no such problem (for now), so it's quite complicated to nail down the problem further as I cannot easily disrupt the availability of the production instance.

All I could do for now is not to use the "DESC" command and reorder the data in my application, but that is really suboptimal as I have to keep all results in memory.

Any help is really appreciated!

Update: I tried the same query with the following code with C++ / SQLDBC (I modified one of the SQLDBC examples):

<pre>
First you have to include SQLDBC.h
#include "SQLDBC.h"
#include <stdio.h>
typedef struct ConnectArgsT {
 char * username;
 char * password;
 char * dbname;
 char * host;
} ConnectArgsT;
static void parseArgs (ConnectArgsT * connectArgs, int argc, char **argv);
using namespace SQLDBC;
Let start your program with a main function
int main(int argc, char *argv[])
 ConnectArgsT connectArgs;
 parseArgs (&connectArgs, argc, argv);
 char errorText[200];
Every application has to initialize the SQLDBC library by getting a
reference to the ClientRuntime and calling the SQLDBC_Environment constructor.
 SQLDBC_IRuntime *runtime;
 runtime = SQLDBC::GetClientRuntime(errorText, sizeof(errorText));
 if (!runtime) {
 fprintf(stderr, "Getting instance of the ClientRuntime failed %s", errorText);
 return (1);
 SQLDBC_Environment env(runtime);
Create a new connection object and open a session to the database.
 SQLDBC_Connection *conn = env.createConnection();
 SQLDBC_Retcode rc;
 rc = conn->connect(connectArgs.host, connectArgs.dbname,
 connectArgs.username, connectArgs.password);
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Connecting to the database failed %s", conn->error().getErrorText());
 return (1);
 printf("Sucessfull connected to %s as user %s\n",
 connectArgs.dbname, connectArgs.username);
Create a new statment object and execute it.
 SQLDBC_Statement *stmt = conn->createStatement();
 rc = stmt->execute("select * from torder where customerid=1624 order by torderid desc");
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Execution failed %s", stmt->error().getErrorText());
 return (1);
Check if the SQL command return a resultset and get a result set object.
 SQLDBC_ResultSet *result;
 result = stmt->getResultSet();
 if(!result) {
 fprintf(stderr, "SQL command doesn't return a result set %s", stmt->error().getErrorText());
 return (1);
Position the curors within the resultset by doing a fetch next call.
 while (1) {
 rc = result->next();
 if(SQLDBC_OK != rc) {
 break;
 //fprintf(stderr, "Error fetching data %s", stmt->error().getErrorText());
 //return (1);
 char szString[30];
 char szString1[3000];
 SQLDBC_Length ind;
Get a string value from the column.
 rc = result->getObject(1, SQLDBC_HOSTTYPE_ASCII, szString, &ind, sizeof(szString));
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Error getObject %s", stmt->error().getErrorText());
 return (1);
 rc = result->getObject(8, SQLDBC_HOSTTYPE_ASCII, szString1, &ind, sizeof(szString1));
 if(SQLDBC_OK != rc) {
 fprintf(stderr, "Error getObject %s", stmt->error().getErrorText());
 return (1);
 printf("%s %s\n", szString, szString1);
Finish your program with a returncode.
 return 0;
static void parseArgs (ConnectArgsT * connectArgs, int argc, char **argv)
setting defaults for demo database
 connectArgs->username = (char*)"USER";
 connectArgs->password = (char*)"PASS";
 connectArgs->dbname = (char*)"MYDB";
 connectArgs->host = (char*)"localhost";
use values from command line
 if (argc > 4) {
 connectArgs->host = argv [4];
 if (argc > 3) {
 connectArgs->dbname = argv [3];
 if (argc > 2) {
 connectArgs->password = argv [2];
 if (argc > 1) {
 connectArgs->username = argv [1];
</pre>

This works!! So it seems, that the problem is related to the Python module, which is interesting, as adding "DESC" should not be any difference to it. I personally suspect that there are some memory leaks in the code, which result in this strange behavior.

Any suggestions?

Which is better storing string values in Map or String buffer

Hi,
I have a store a 10 string values in a cookie. Do i use a String buffer and append all values or put it in a hash map.
If i put in a string buffer i have to use a string tokenizer to loop and extract the values., but if i am using a map then
retrieval will be easier, but in terms of memory management, which is better. as i have to create this cookie for every unique IP hitting my site.
Thanks,
Viiveek

That doesn't make it a good idea. The bytes of memory you'd lose by using a Map would be made up by the fact that Map was expressly made for storing key/value pairs. Memory management should be about the 200th factor you should consider.

Binary values corrupted in Content Manager

Hello,
When I copy and paste (or move) a content that has a property binary, in the second instance (the copy) these properties are corrupted. When I try to access to these properties, I receive the next exception:

I'm working with WLPortal 10.3.
Is this a bug of Portal?
Is there any way to do this and the data are not corrupted?
Thanks.

When I copy or move there isn't exception, but when I access to the binary property of copy, it log this exception:

Losing the leading zero in binary values

Hi all,
I�m currently creating some basic examples of bitwise operations and I�ve just noticed that I�m losing the leadnig zero of a binary value ( e.g.
decimal 1 (expecting to see bin of 0001) is manifesting as 1
decimal 16 (expecting to see bin of 00010000) is manifesting as 10000
below is a full example
import static java.lang.Integer.*;
public class BitExample {
public static void main(String[] args) {
System.out.println(
     toBinaryString(0x1) + '\n' +
     toBinaryString(0x16) + '\n' +
     toBinaryString(0x6a) + '\n' +
     toBinaryString(0x80)
I can see I�m missing something, but not sure what. Can you help?
Many Thanks
Giles

which obviously returns a very different resultNo it does not ... let's translate the example to decimal (with additions instead of bitwise operations, but that doesn't change anything:
1234 +
0001
1235and
1234 +
1
1235both notations are correct, aren't they? Now the second one doesn't look so nice (and usually the 1 should be right-aligned to be easily readable, but it isn't wrong, because of this.
The same is true for binary operations. The problem is, that while learning bitwise operations it's easier to unserstand if you always write the leading zero (as you do in your example).

Binary value to string

Hi,
I want to convert binary value to string format. How can i do that if possible please give me sample code.?
One more question is i want to do reverse thing also that is convert string value to binary format.?
Waiting for reply

There are methods in Integer, Long etc for transforming to binary.
I think there are probably also methods to go from binary to an int. Check out the JavaDoc

Storing the value of apex_item.radiogroup!

Hi All,
I am using an APEX_ITEM.RADIOGROUP api to display the rating from 1 to 5.
In order to store the value of radio button selected, I am using a textbox item.
e.g.
P2_ques_1 = rating value from 1-5( coming from radio group)
P2_ques_2 = rating value from 1-5
Now I want to save the value of P2_ques_1... into the database through a loop.
for i in 1..4 loop
l_rating := :P2_QUES_||i;
INSERT INTO org_feedback(feedback_id,question_id,rating,org_contact_id)
VALUES(ORGFEEDBACKSQ.NEXTVAL,i,l_rating,:P2_CONTACT_ID);
end loop;
The above loop is storing the value of "i" instead of values of : P2_QUES_1,: P2_QUES_2....
Is there any way or suggestion I can achieve this?
Thanks,
- Parveen Sehrawat

I can't catch you.
Let me explain what i want to do...
I have radio button in forms as well as in reports.
In FORMS i created a RADIO GROUP using STATIC LOV
Like,
STATIC:GOOD;3,NOTBAD;2,BAD;1
So at runtime i can easily get this radio group values.
In REPORTS i created RADIO GROUP using SELECT QUERY
Like,
with t as(
select 'problem_sol' as others, 1 as num from cand_performance
union
select 'communication' as others, 2 as num from cand_performance
union
select 'attitude' as others, 3 as num from cand_performance)
select others,
apex_item.radiogroup(num) as good,
apex_item.radiogroup(num) as notbad,
apex_item.radiogroup(num) as bad
from t
Now i want to define values for those radio button like what i define in STATIC LOV radio buttons and i want to know how to get the selected value when user submit the page... Again i'm telling i have radio button in REPORTS.
