EXP-00002 tips Oracle Database Tips by Burleson Consulting December 19, 2015 Question: I'm running an export (expdp) exp overflow error on a Windows server, and I'm getting the "EXP-00002: error in writing to export file" error: EXP-00002: error in writing to export file EXP-00002: error in writing to export file EXP-00000:
Exp-00011
Export terminated unsuccessfully How do I fix the output file? Answer: The docs note this on the ORA-0002 error, a generic file write problem: EXP-00002: error in writing to export file Cause: Export could not write to the export file, probably because of a device error. This message is usually followed by a device message from the operating system. Action: Take exp-00026 conflicting modes specified appropriate action to restore the device. This EXP-00002 error is hardware related, and you need to see the accompanying OS message to see details. This EXP-00002 error is common when the expdp writing has filled the destination output file, as defined in the parfile. Check the output file name in your export parameter file, and see the space usage. This can also happen on 32-bit servers when the file size exceeds two gigabytes, requiring the use of the split command to separate the exp output onto multiple files. The EXP-00002 can also occur if the directory permissions are wrong, and do not allow writing into the diectory.

overflow in the DOUBLE data type in MySQL I found. You can refer to my previous post on BIGINT Overflow Error based injections if you want to

my previous post. When we take the functions in MySQL I was interested in the mathematical functions. They too should contain some data type to hold values. So I went on testing for functions which would cause any overflow errors and I found out that exp() would cause a http://www.dba-oracle.com/t_exp_0002.htm overflow error when we pass a large value above 709. mysql> select exp(709); +-----------------------+ | exp(709) | +-----------------------+ | 8.218407461554972e307 | +-----------------------+ 1 row in set (0.00 sec) mysql> select exp(710); ERROR 1690 (22003): DOUBLE value is out of range in 'exp(710)' The exp is the opposite of the ln and log functions of MySQL. If I briefly explain the functionality https://osandamalith.com/2015/07/15/error-based-sql-injection-using-exp/ of these, log and ln and both returns the answer to the natural logarithm or to the base e. In common e is approximated to: . mysql> select log(15); +------------------+ | log(15) | +------------------+ | 2.70805020110221 | +------------------+ 1 row in set (0.00 sec) mysql> select ln(15); +------------------+ | ln(15) | +------------------+ | 2.70805020110221 | +------------------+ 1 row in set (0.00 sec) Exponentials are the opposite of logarithms. The exp function would do the exact opposite for us. mysql> select exp(2.70805020110221); +-----------------------+ | exp(2.70805020110221) | +-----------------------+ | 15 | +-----------------------+ 1 row in set (0.00 sec) Injection When it comes to injection we can cause these “DOUBLE value is out of range” errors by negating queries. Suppose I do a bitwise negation a query it will return “18446744073709551615”. If you may recall from my previous post this is the bitwise negation of 0. This is due to the reason that a function returns 0 on a successful execution and when we negate it will be the maximum unsigned BIGINT value. mysql> select ~0; +----------------------+ | ~0 | +----------------------+ | 18446744073709551615 | +--------------

This is what I have: >>> from fractions import Fraction >>> f13=Fraction('1/3') >>> f23=Fraction('2/3') >>> f43=Fraction('4/3') >>> f53=Fraction('5/3') >>> f12=Fraction('1/2') >>> f32=Fraction('3/2') >>> f56=Fraction('5/6') >>> fm1=Fraction('-1') >>> fm23=Fraction('-2/3') >>> fm32=Fraction('-3/2') >>> from matplotlib import pyplot as plt >>> import numpy as np >>> x=np.arange(0.01,2,0.01) >>> xa=x/(1+0.1071*x) >>> rate=(4.817e+6)*(x**fm23)*np.exp(-14.964/(x**f13))*(1+0.0325*(x**f13)-(1.04e-3)* (x**f23)-(2.37e-4)*x-(8.11e-5)*(x**f43)-(4.69e-5)*(x**f53))+(5.938e+6)*(xa**f56)*(x**fm32)*np.exp(-12.859/(xa**f13)) And when I enter it, it gives me this error: Traceback (most recent call last): File "
