linux - [01000][unixODBC][Driver Manager]Can't open lib '/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so' : file not found

Question

I am trying to acces oracle from linux server. I am using unixODBC.

When i try to acces oracle using isql and i get error that driver manager can't open libsqora.so.12.1.

 [Oracle 11g ODBC driver]
 Description=Oracle ODBC driver for Oracle 11g
 Driver=/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so

Then, when i use isql to acces oracle i get the following error:

 [root@xxxxx lib]# isql -v NAME
 [01000][unixODBC][Driver Manager]Can't open lib '/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so' : file not found
 [ISQL]ERROR: Could not SQLConnect

I had typo in odbcinst.ini. I have corrected but still same error.

Fixed original issue with LD_LIBRARY_PATH updates but now it is broken again since I am trying to use the 32bit Oracle client.

Installed 32bit oracle client in directory /opt/oraClient/11.2.0.4_32/.

Modified the odbcinst.ini:

Error:

[root@xxxxx lib]# /usr/local/bin/isql -v NAME

 [ISQL]ERROR: Could not SQLConnect

If I need to use the 32bit Oracle client, what am i doing wrong...I know it is something in environmental variables.

 [root@xxxxx lib]# file /opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1
 /opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), not stripped

I enable trace but am not able to attach document here. I can email.

More debug info:

 [root@xxxxx bin]# ldd /opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1
 ldd: warning: you do not have execution permission for `/opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1'

I don't get one the "not found" which may be causing some problems:

 [root@xxxxx bin]# ls /opt/oraClient/11.2.0.4_32/lib/libclntsh.so.11.1

Answer 1

This error is misleading:

The file that the error claimed was not present did exist.

I was able to chase down the actual missing file by executing:

# ldd /path/to/your/socalled/missing/file.so

This returned a series of files and one said:

libodbcinst.so.2 => not found

That is was the culprit for me. I then created the link that I needed and voila, the error went away.
