Hi,
as the title says, I am after a simple script, which will open the Alert log from
an 11.2.0.1 Linux environment and mail the error message and description to a recipient email address.
I can then schedule this job via cron and let it run every 15 minutes.

Hi,
I'm trying to write a shell script on HP-UX to search through Oracle alert logs for errors which always start with ORA-. If it does find an error I'd like it to print the date line (which precedes the error by a line or two normally) as well as the error line. So in the example below I'd like... (1 Reply)

I need to check 1 log file, which is logging:
2014-08-18T09:10:39+02:00 user: XXXXX START FEATURE

I first need to check that the START FEATURE starts and finish on the same time/date for the same user, which is different each time START... (2 Replies)
Please provide Shell script to capture ORA errors from Alert Log for a given date or Current date.

log2
LOG(3) BSD Library Functions Manual LOG(3)NAME
log, log2, log10, log1p, -- logarithm functions
SYNOPSIS
#include <math.h>
double
log(double x);
long double
logl(long double x);
float
logf(float x);
double
log2(double x);
long double
log2l(long double x);
float
log2f(float x);
double
log10(double x);
long double
log10l(long double x);
float
log10f(float x);
double
log1p(double x);
long double
log1pl(long double x);
float
log1pf(float x);
DESCRIPTION
The log() function computes the value of the natural logarithm of argument x.
The log2() function computes the value of the logarithm of argument x to base 2.
The log10() function computes the value of the logarithm of argument x to base 10.
If x is nearly zero, then the common expression log(1 + x) will not be able to produce accurate results, as most (or all) of the information
in x will be lost by addition. Instead, use log1p(x) to perform the same computation without undue loss of accuracy. If you find yourself
using this function, you are likely to also be interested in the expm1() function.
SPECIAL VALUES
log(+-0), log2(+-0), and log10(+-0) return -infinity and raise the "divide-by-zero" floating-point exception.
log(1), log2(1), and log10(1) return +0.
log(x), log2(x), and log10(x) return a NaN and raise the "invalid" floating-point exception for x < 0.
log(+infinity), log2(+infinity), and log10(+infinity) return +infinity.
log1p(+-0) returns +-0.
log1p(-1) returns -infinity and raises the "divide-by-zero" floating-point exception.
log1p(x) returns a NaN and raises the "invalid" floating-point exception for x < -1.
log1p(+infinity) returns +infinity.
VECTOR OPERATIONS
If you need to apply the log() functions to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may
give significantly better performance:
#include <Accelerate/Accelerate.h>
vFloat vlogf(vFloat x);
vFloat vlog1pf(vFloat x);
vFloat vlog10f(vFloat x);
void vvlogf(float *y, const float *x, const int *n);
void vvlog(double *y, const double *x, const int *n);
void vvlog1pf(float *y, const float *x, const int *n);
void vvlog1p(double *y, const double *x, const int *n);
void vvlog10f(float *y, const float *x, const int *n);
void vvlog10(double *y, const double *x, const int *n);
void vvlog2f(float *y, const float *x, const int *n);
void vvlog2(double *y, const double *x, const int *n);
SEE ALSO exp(3), pow(3), math(3)STANDARDS
The log(), log2(), log10,() and log1p() functions conform to ISO/IEC 9899:2011.
