Hi all,

While trying to setup RQM Live reporting on our RRDI 2.0.1 server, I have run into the following error message while testing the setup:

[ISQL]ERROR: Could not SQLConnect
 
at Step 10 of Configuring the ODBC driver for Linux and AIX systems.

I have tried this lots of times over the last few days with many different settings for my PATH and/or LD_LIBRARY_PATH environment variables to no avail.

Clearly the wrong version of java is being used with the jar file but why? and how do I configure it to use the correct one?

Many Thanks In Advance,

Robin

Hello Robin,

I recently found that the file libodbcinst.so could be missing or miss-linked,  this occured to us when we had a system that contain the 32 and 64 bit version of the linuxODBC code.  and after removing the 64bit version of the linuxODBC, the tool could no longer find /opt/unixODBC/lib/libodbcinst.so.

Or the second option for this problem is that the libodbcinst.so, is at the wrong bit level.   If you execute a "file" against the library for the libodbcinst.so. 

WARNING:  it is possible that libodbcinst.so is a symbolic link,  use the file command against the targeted link if it is, in the example below libodbcinst.so.1.0.0 if the file I test against

[root@oraeuro1 lib]# ls -lsa libodbcinst.*
 0 lrwxrwxrwx 1 root root    29 May 17 10:35 libodbcinst.so -> /usr/lib/libodbcinst.so.1.0.0
 0 lrwxrwxrwx 1 root root    20 May 17 10:11 libodbcinst.so.1 -> libodbcinst.so.1.0.0
80 -rwxr-xr-x 1 root root 74724 Oct 18  2011 libodbcinst.so.1.0.0

Example:

[root@oraeuro1 lib]# file libodbcinst.so.1.0.0
libodbcinst.so.1.0.0: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), stripped
[root@oraeuro1 lib]#

Make sure the file is 64 bit, if it is remove and re-install you linuxODBC, 

Hope this heps

CORRECTION:

Make sure the file is 64 bit, if it is remove and re-install you linuxODBC, 

SHOULD BE

Make sure the file is not 64 bit, if it is remove and re-install you linuxODBC,
