I have a program called "myProg" which calls two other programs "prog1" and "prog2" with system command in it.
When I type
to the terminal, everything is cool. The only things that are missing:
1) I would like to measure the time elapsed when myProg runs (I do not want the change the code).
2) I also want to measure the maximum memory which is used by myProg during execution.
How can you make a program as Memory resident in AIX.
If I make a program as a memory resident program whether all the parts of the program like code and data (stack) segements of the program will be loaded in to the Memory.
For Ex:
I have a C code which is creating array of 10000 long ints... (4 Replies)

Are the programs written on schedulers ,thread library , process management, memory management, et al called systems programs ? How are they different from the programs that implement functions like open() , printf() , scanf() , read() .. they have a prefix sys_open, sys_close, sys_read etc , right... (1 Reply)
Dear all,
i am not getting the exact things what i am expecting from
these commands . just clarify this things ,
1. cpu utilization (min)%
2.peak load cpu utilization (max) %
3.cpu utilization(avg)
4. peak disk busy %
5. peak kb read
6.peak kb write
7.free memory

I'm involved in a project with multiple teams which are developing C code for a Linux machine and we would like to have our program pass data to one of the other group's programs. The immediate idea is to have shared memory between the programs which would simply consist of variables whose size and... (2 Replies)
I am constantly getting request to run reports on our AIX server for system health (cpu, io, memory, etc) when users experience performance issues. We are using SolarWinds to monitor system health and it works great for cpu and disk space; however, I cant seem to get memory and io to work... (5 Replies)
unix and linux does not makes executable files for all the programs.
it compiles it and executes it whenever require.
at the time of booting the system, how kernel compiles those c programs without "gcc". (1 Reply)
Dear,
How to calculate %computational memory and %non computational memory from AIX server.
What command used to find out %computational memory and % non computational memory except topas.

Hey guys,
Suppose i run passwd via bash shell. It is a suid program, which temporarily runs as root(owner) and modifies the user entries.
However, when i write a C file and give 4755 permission and root ownership to the 'a.out' file , it doesn't run as root in bash shell. I verified this by... (2 Replies)

ecpg
ECPG(1) PostgreSQL Client Applications ECPG(1)NAME
ecpg - embedded SQL C preprocessor
SYNOPSIS
ecpg [ option... ] file...
DESCRIPTION
ecpg is the embedded SQL preprocessor for C programs. It converts C programs with embedded SQL statements to normal C code by replacing the
SQL invocations with special function calls. The output files can then be processed with any C compiler tool chain.
ecpg will convert each input file given on the command line to the corresponding C output file. Input files preferrably have the extension
.pgc, in which case the extension will be replaced by .c to determine the output file name. If the extension of the input file is not .pgc,
then the output file name is computed by appending .c to the full file name. The output file name can also be overridden using the -o
option.
This reference page does not describe the embedded SQL language. See the PostgreSQL Programmer's Guide for that.
OPTIONS
ecpg accepts the following command-line arguments:
-c Automatically generate C code from SQL code. Currently, this works for EXEC SQL TYPE.
-D symbol
Define a C preprocessor symbol.
-I directory
Specify an additional include path, used to find files included via EXEC SQL INCLUDE. Defaults are . (current directory),
/usr/local/include, the PostgreSQL include directory which is defined at compile time (default: /usr/local/pgsql/include), and
/usr/include, in that order.
-o filename
Specifies that ecpg should write all its output to the given filename.
-t Turn on autocommit of transactions. In this mode, each query is automatically committed unless it is inside an explicit transaction
block. In the default mode, queries are committed only when EXEC SQL COMMIT is issued.
-v Print additional information including the version and the include path.
---help
Show a brief summary of the command usage, then exit.
--version
Output version information, then exit.
NOTES
When compiling the preprocessed C code files, the compiler needs to be able to find the ECPG header files in the PostgreSQL include direc-
tory. Therefore, one might have to use the -I option when invoking the compiler (e.g., -I/usr/local/pgsql/include).
Programs using C code with embedded SQL have to be linked against the libecpg library, for example using the flags -L/usr/local/pgsql/lib
-lecpg.
The value of either of these directories that is appropriate for the installation can be found out using pg_config(1).
EXAMPLES
If you have an embedded SQL C source file named prog1.pgc, you can create an executable program using the following sequence of commands:
ecpg prog1.pgc
cc -I/usr/local/pgsql/include -c prog1.c
cc -o prog1 prog1.o -L/usr/local/pgsql/lib -lecpg
