AIX Commands

C program to analyze core files by cspilman
Posted: 28 Mar 02

This is tried and tested on AIX 4.3 versions:


#include <stdio.h>
#include <sys/core.h>

void main(int argc, char *argv[])
{
        FILE *corefile;
        struct core_dumpx c_file;
        char command[256];

        if (argc != 2)  {
           fprintf(stderr, "Usage: %s <corefile>\n", *argv);
           exit(1);
        }

        if ((corefile = fopen(argv[1], "r")) == NULL)  {
           perror(argv[1]);
           exit(1);
        }

        fread(&c_file, sizeof(c_file), 1, corefile);
        fclose(corefile);

        sprintf(command, "lquerypv -h %s 6E0 64 | head -1 | awk '{print $6}'", argv[1]);

        printf("Core created by: \n");

        system(command);

        printf("Signal number and cause of error number: %i\n", c_file.c_signo);
        printf("Core file type: %i\n", c_file.c_flag);
        printf("Number of core dump modules: %i\n", c_file.c_entries);
        printf("Core file format number: %i\n", c_file.c_version);
        printf("Thread identifier: %i\n", c_file.c_flt.th.ti_tid);
        printf("Process identifier: %i\n", c_file.c_flt.th.ti_pid);
        printf("Current effective priority: %i\n", c_file.c_flt.th.ti_pri);
        printf("Processor Usage: %i\n", c_file.c_flt.th.ti_cpu);
        printf("Processor bound to: cpu%i\n", c_file.c_flt.th.ti_cpuid);

/*      if (c_file.c_flt.th.ti_cpu > 1) printf("Last Processor: cpu%i\n", c_file.c_flt.th.ti_affinity);
*/
        exit(0);
}
