Не подскажете в чем здесь проблема.
Использую
Apache 2.0.54
PHP 5
Windows Xp

Настройки PHP.ini

extension=php_sybase_ct.dll

[Sybase]
sybase.allow_persistent = On
sybase.max_persistent = -1
sybase.max_links = -1
sybase.interface_file = "/usr/sybase/interfaces"
sybase.min_error_severity = 10
sybase.min_message_severity = 10
sybase.compatability_mode = Off

[Sybase-CT]
sybct.allow_persistent = On
sybct.max_persistent = -1
sybct.max_links = -1
sybct.min_server_severity = 10
sybct.min_client_severity = 10


Код простой

$link = sybase_connect ('10.17.1.146', 'login', 'password') or die("Could not connect !");
echo "Connected successfully";
sybase_close($link);

Результат
Warning: sybase_connect() [function.sybase-connect]: Sybase: Unable to allocate connection record in D:\www\html\work\tmp\db.php on line 7
