Troubleshooting an HPUX program

In investigating the problems with sawserver I was pointed towards a tool called tusc (which appears to be an HP version of truss).

You can use it to invoke a program, and get out a bunch of debug information including system calls.

You run it like this:

$tusc -fep /app/oracle/product/obiee/web/bin64/sawserver64

As a beginner when it comes to hardcore *nix I can only look at this and take pot shots at what’s going on, but with Google by my side I’m interested in the last lines of the output:

open("/app/oracle/product/10.2.0/lib/libstd_v2.so.1", O_RDONLY|0x800, 0) ……… ERR#2 ENOENT
open("/app/oracle/product/obiee/server/Bin64/libstd_v2.so.1", O_RDONLY|0x800, 0) . ERR#2 ENOENT
open("/app/oracle/product/obiee/web/bin64/libstd_v2.so.1", O_RDONLY|0x800, 0) …. ERR#2 ENOENT
open("/app/oracle/product/obiee/odbc/lib64/libstd_v2.so.1", O_RDONLY|0x800, 0) … ERR#2 ENOENT
open("/usr/lib/libstd_v2.so.1", O_RDONLY|0x800, 0) …………………………. ERR#2 ENOENT
open("/lib/libstd_v2.so.1", O_RDONLY|0x800, 0) …………………………….. ERR#2 ENOENT
open("/app/oracle/product/10.2.0/lib/libstd_v2.so.1", O_RDONLY|0x800, 0) ……… ERR#2 ENOENT
open("/opt/aCC/lib/hpux64/libstd_v2.so.1", O_RDONLY|0x800, 0) ……………….. ERR#2 ENOENT

This is the last output before the process hangs, and ENOENT is a file or directory not found error. It looks like it’s scanning different folders for the file

This makes me think there’s something up with the path/load library environment variables (but why on all our servers and only now??).
