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

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.

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

 [root@xxxxx lib]# isql -v NAME

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

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

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

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.

Instant client doesn't have a lib directory. If you've downloaded the instantclient-odbc-linux package and unzipped that in the same location as the basic package then the libsqora.so.11.1 file will be durectly under /usr/local/easysoft/oracle/InstantClient112.

So your .ini should point to:

Driver=/usr/local/easysoft/oracle/InstantClient112/libsqora.so.11.1

Note the extension though; you might want to soft-link that to libsqora.so. If you've moved the .so files into a subdirectory after unzipping (?) then you'd need:

Driver=/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so.11.1

It looks like you've reoriganised the instant client files after unzipping, creating a lib directory. I'm not sure if that will directly cause you problems. But you also haven't set LD_LIBRARY_PATH, as the installation instructions suggest:

Installation Steps:

Download the appropriate Instant Client packages for your platform. All installations REQUIRE the Basic package.

Unzip the packages into a single directory such as "instantclient".

Set the library loading path in your environment to the directory in Step 2 ("instantclient"). On many UNIX platforms, LD_LIBRARY_PATH is the appropriate environment variable. On Windows, PATH should be used.

Start your application and enjoy.

Clearly step (4) isn't working for you yet, but I think that's because you haven't done step (3); and I think as you've split the files - which might itself cause an issue - you may need to include both .../InstantClient112 and .../InstantClient112/lib in the LD_LIBRARY_PATH variable. And make sure the modified value is exported. I'm not sure why you'd want to rearrange the files though.
