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

问题:

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.

odbc.ini

odbcinst.ini

 [Oracle 11g ODBC driver]  Description=Oracle ODBC driver for Oracle 11g  Driver=/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so  FileUsage=1 

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:

[Oracle 11g ODBC driver] Description=Oracle ODBC driver for Oracle 11g #Driver=/usr/local/easysoft/oracle/InstantClient112/lib/libsqora.so.11.1 Driver=/opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1 FileUsage=1 

Error:

[root@xxxxx lib]# /usr/local/bin/isql -v NAME                                                        [01000][unixODBC]  [Driver Manager]Can't open lib '/opt/oraClient/11.2.0.4_32/lib/libsqora.so.11.1' : file not found  [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'     linux-gate.so.1 =>  (0xffffe000)     libdl.so.2 => /lib/libdl.so.2 (0xf7f2b000)     libm.so.6 => /lib/libm.so.6 (0xf7f02000)     libpthread.so.0 => /lib/libpthread.so.0 (0xf7ee8000)     libnsl.so.1 => /lib/libnsl.so.1 (0xf7ecf000)     libclntsh.so.11.1 => not found     libodbcinst.so.1 => not found     libc.so.6 => /lib/libc.so.6 (0xf7d71000)     /lib/ld-linux.so.2 (0x00134000) 

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

回答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.

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:

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

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

3. 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.

4. 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.
