utility library error function string?

I'm working on a library Error Handler, slaughtered most of these wonderful for a (Roberto!). I can't find a generator of string of code error for the functions in the library of good content (in particular, functions like RenameFile, CopyFile, GetDir, SetDir, MakeDir, all file IO functions).

Most people refer to types of maximum error tolerated with some explanations of plain text. But there is no mention of a nice string code converter function, as it is in other libraries. For example, for the RS232 library, there are GetRS232ErrorString. Formatting & IO Library, there is GetFmtIOErrorString.

I don't see it somewhere? Inside the library of utilities, there is a function called CmtGetErrorMessage multithreaded error code.

You are right: the library of Urility does not include a function that translates into a meaningful text error codes. I guess that it is due to the fact that error codes overlap in part, so a single function could not be used.

For example, the-1 error means file not found in almost all file IO Library functions, but it translates into no file found matching the criteria of research GetFirstFile (), for not more files in GetNextFiles () and invalid parameters in MakePathname ().

Another example: error-2 means GetFirstFile must be called before if returned by GetNextFile () and resulting path too long if returned by MakePathname ().

And cela given that e/s file section of the library!

While developing my own toolbox of utilities, I created the following function I know is far from perfect and covers only the file IO features:

char * CVIFUNC GetULibFileIOErrMsg (int error)

// Messages associated to error codes returned by functions in File Utilities class in Utility Library
{
    switch (error) {
        case 0: return "Success";
        case -1:    return "One of the path component not found";
        case -2:    return "Resulting pathname longer than 260 chars";
        case -3:    return "General I/O error occurred";
        case -4:    return "Insufficient memory to complete operation";
        case -5:    return "Invalid path";
        case -6:    return "Access denied";
        case -7:    return "Specified path is a directory, not a file";
        case -8:    return "Disk is full";
        case -9:    return "New file already exists";
        default:    return "Unknown error";
    }
    return NULL;
}

Here is the PLSQL block that I will carry out and also the output on this block

declare 
lv_ftp_result boolean; 
begin 
lv_ftp_result := u.FTP('XXAR_REV_PA', ' ' || '/u07/app/qaoa083a/data/outgoing/xxar/PARECREV' || '/' || 'REVENUE_20120319014318.dat','REVENUE_20120319014318.dat');  
IF lv_ftp_result THEN 
dbms_output.put_line('True'); 
ELSE 
dbms_output.put_line('False'); 
END IF; 
exception 
when others then 
dbms_output.put_line('in exception - '||sqlerrm); 
end;

Output:

host1 begin
host2 begin
m=1
result_out - ERROR : GLCC0005 presumed not running
not derun
begin
Looping
host
host1 begin
host2 begin
m=1
in exception - ORA-06502: PL/SQL: numeric or value error: character string buffer too small

The flow of execution goes like this:
1 FTP function called from PL/SQL block
2 inside of the FTP service, the Sub statement calls the HOST function

log_dir              varchar2(100) := get_env('$APPLCSF')||'/log';

3. This HOST function in turn calls another function of overloaded HOST (code shown above).
4. in the function overloaded with the HOST, the following statements are executed successfully, and FALSE is returned by the function

dbms_output.put_line('m=1');
result_out := 'ERROR : GLCC0005 presumed not running';
dbms_output.put_line('result_out - '||result_out);

5. the remaining code in the FTP service is running and the HOST function is called again using the Sub statement

res := HOST('echo $$',proc_id);

6.again, this HOST function in turn calls another function of overloaded HOST (code posted above).
7. this time, in the function overloaded host, ORA-06502 is thrown when the following statement is executed and the execution stops here that this exception is unhandled.

result_out := 'ERROR : GLCC0005 presumed not running';

This statement is very successfully in the previous call to the function of HOST (step 4), but it fails now.

Any idea on why this error occurs in this scenario? Because the issue of memory?

Hello

HOST (1) calls the function of MODERATOR (2) with his second parameter as result_out

The first time you call the function of host (1) in the function get_env you use

...
 out varchar2(256);
BEGIN
  res := HOST('echo '||env,out);
...

out is big enough varchar2 (256)

The second time you call (1) HOST of the FTP function as:

...
ftp_main         varchar2(2000);
proc_id           varchar2(10);
fderr             varchar2(100);
...

...
          res := HOST('echo $$',proc_id);
          dbms_output.put_line('proc_id - '||proc_id);
...

Here, use you proc_id which is varchar2 (10)

And it's not big enough!

Kind regards

XQuery question fn:error function

I want to use the integrated XQuery my custom XQuery function error function & propagate them to the OSB failure mechanism and was trying to do: -.

MyCustomXQuery.xq

declare function local: doesntContainDefaultValue ($siebelMessage1 as element(ns4:SiebelMessage), $processLineItem1 as element (ns1:processLineItem)) as XS: Boolean))

Gives me a compilation error-

Any ideas what's not here? I use function error correctly?

Thank you
Buxant
See w3c doc: http://www.w3.org/TR/xpath-functions/#func-error on a valid signature for error().

The first argument must be a QName.

FN:Error() because none
FN: Error($Error As XS:QName) as none
FN: Error($Error As XS:QName?, $description As XS:String) as none
FN: Error ($error as XS: QName?,)
$description as XS: String.
($error - object as item() *) as none

Examples
1 fn:error() returns http://www.w3.org/2005/xqt-errors#FOER0000 (or the corresponding XS: QName) to the external processing environment.

2 fn:error (fn:QName('http://www.example.com/HR',_'myerr:toohighsal'), "Does not apply because salary is too high") returns http://www.example.com/HR#toohighsal and the XS: String "does not apply because salary is too high" (or the corresponding XS: QName) to the external processing environment.

When booting I get the Visual C++ runtime library error message. This application has requested the execution in an unusual way. Any ideas how to fix?

When booting I get the Visual C++ runtime library error message

Hi ToddLynch,

(1) since when are you facing this problem?

(2) remember to make changes?

It is sufficient to indicate the complete error message you receive.

Put the computer to boot and then check if the problem persists

Follow step 1 in the link below,

How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

Continue with the remaining steps to pin-point on the third party service.

After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

Important: n ' forget not to put the computer to a normal startup follow step 7 in the link.

You can put your boot system to solve the problem.

To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts. This article describes how to solve problems in Windows Vista or Windows 7 by performing a clean boot.
