[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.

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:

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

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

More debug info:

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

Solution 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.

Solution 2

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.

The base instant client doesn't have that file (or a lib directory). So is it really the instant client as the path suggests, or a full client (or server)?

[user3521305]

Fixed...still not working.

[Alex Poole]

If you've rearranged the instant client files, I don't know if that might be confusing internals links - perhaps the error is abput another that one then can't find? You might also need to add the lib directory (and/or its parent) to LD_LIBRARY_PATH, does that make any difference?

[user3521305]

I updated the LD_LIBRARY_PATH with your feedback and it worked.

[user3521305]

I got isql working but found out that the the application that i am building this for only supports 32bit oracle client. Therefore I installed 32bit oracle and have broken it again. I am getting the same error now when executing sql.

[user3521305]

This is company pacakged build for unixODBC and looks like they included the oracle driver and instantclient. But i am pointing the driver to the 32bit oracle installation under /opt/oraClient/11.2.0.4_32/.

[user3521305]

Please help...I have tried every alteration to the odbsinst.ini file.

[Alex Poole]

@user3521305 - if you're now getting ORA-01017, that isn't a driver or environment problem. You're successfully contacting a database, but whether it's the right one depends on where your SMARTS_SDI_NA DSN is pointing. That is the wrong DB instance, or the username or password in your odbc.ini are wrong for that DSN. Remember those are case-sensitive in 11g. One of those three must be wrong, I think, most likely the password. Check you can connect with a different client.

[user3521305]

I pasted the wrong output...the ORA-01017 is for the working one with the 64bit oracle driver...I can get that to work. My problem is when i try to use the 32bit oracle driver.

[Alex Poole]

OK, then that file definitely exists - you got the 32-bit ODBC package - and you set LD_LIBRARY_PATH to that new location?

[user3521305]

Yes. I installed the 32bit Oracle client and set the LD_LIBRARY_PATH. Detail of the contents are above.

[Alex Poole]

@user3521305 - the not found still suggests LD_LIBRARY_PATH isn't set, or isn't exported.

[user3521305]

I pasted the latest env output above...As you can see I have set the LD_LIBRARY_PATH. I think it has something to do with something to do with a missing file pointer for 32bit odbc driver.

[user3521305]

The only thing i can think of is to install the 32bit Oracle client and driver again from Oracle site. The one I am using right now is a packaged version from my company but it was tested by them so hard to believe it would be broken.

[Alex Poole]

@user3521305 - it's set, but are you sure it's exported? That's the only think I can think of that would cause this behaviour.

[user3521305]

It wouldn't be in env output if it wasn't exported. Is there someone with more experience that could troubleshoot via debug?

[Alex Poole]

@user3521305 - yes it would. It wouldn't be in the output of export if it wasn't exported. Having both Oracle versions in it is confusing but it'll use the first match so shouldn't matter here. The file exists where you expect, the only reason for ldd not to be able to see it is that variable not being set/exported properly, in my experience anyway. Good luck.

[user3521305]

Is someone esle from support going to pick this up or is there no more help coming?

[gfroese]

Thanks for the tip, had the same missing file problem when setting up Linux I Application access on Ubuntu.

[Gert van den Berg]

If the file is present but not in the library path, you can set LD_LIBRARY_PATH or add a file to /etc/ld/conf.d and rerun ldconfig

[Alen]

@user3771500 Can you pls post which links you created, I'm missing these files: libicuuc.so.42 and libicudata.so.42

[avn]

# ldd saved me!

[Alexis.Rolland]

I'd like to know how you "created the link" as well? On my side I have libclntsh.so.12.1 => not found and libclntshcore.so.12.1 => not found
