Porting of Sybase Application to Oracle 8i under Solaris

Question

Dear All
I want to port an application from sybase 10.2 which is running under Solaris to Oracle 8I under Solaris. Apart from database objects and stored procedures which I have already converted I wan to conver some C Codes and Unix Scripts
Which are either shell scripts or perl programs. I need all of your valuable suggestions in this regard.
Q-1 . In the Perl Program the following lines are sybase specific
Use Sybase:: Dblib
Require /files0/apps/local/lib/perl15/Sybase/sybperl.pl;
What will be the equivalent for ORACLE.
Suggest what perl I should use in this context.
In continuation to the above also I have some shell variables assigned as follows
$SYB_SERVER=SYB_PROD_CERT;
$SYB_DATABASE=APPLDB;
$ENV{SYBASE}=/sybase/10.0.4;
$ENV{DSQUERY}=$SYB_SERVER
$SYB_USER=keshav;
$SYB_PWFILE=/myappl/processcert/passwords/$SYB_SERVER;
$SYB_PW=/usr/bin/cat $SYB_PWFILE;
chop($SYB_PW);
dbmsghandle(message_handler);
dberrhandle(error_handler);
( ($dbproc = &dblogin($SYB_USER,$SYB_PW,$SYB_SERVER)) != -1 );
( &dbuse($dbproc, $SYB_DATABASE) != -1 );
( ($dbproc2 = &dblogin($SYB_USER,$SYB_PW,$SYB_SERVER)) != -1 );
( &dbuse($dbproc2, $SYB_DATABASE) != -1 );
sub Statistics
# get distinct sub-cat counts
( &dbcmd($dbproc, "select count(*),orgnumber,name=(select servicerorgname from servicer where servicer.orgnumber=transactionlog.orgnumber) from transactionlog group by orgnumber order by count(*) desc\n") != -1 );
&dbsqlexec($dbproc);
&dbresults($dbproc);
$row = DBROWS( $dbproc );
2. One of the Sample C Program is given here which I want to convert into pro*c.
I would like to know what are the corresponding libraries of oracle under
Solaris are to be used and also the respective header files mapping of Sybase
To Oracle. Any comment of this will be appreciated.

Hello
The "-D_BIG_ENDIAN" shows you that the code is endian-dependent. This means that the program cannot be ported 1:1 because x86 is little endian while Sparc is big-endian.
I would first try to use "-D_LITTLE_ENDIAN" (or what flag ever I can find in the source codes) and to compile for x86.
Because of the "-D_BIG_ENDIAN" different source code is used for both machines. Maybe the little-endian source code is wrong:
#ifdef _BIG_ENDIAN
// correct source code for Sparc
#else
// INCORRECT source code for x86
#endifMartin
