Data Flow Failure – Missing libcrypto.so.10 dependency (OAS 2025)

Hello,
After migrating from OBIEE to Oracle Analytics Server (OAS) 2025, we encountered a failure when running any Data Flow. The error message is:

[nQSError: 36001] Unable to load the dll /opt/weblogic/middleware/bi/bifoundation/server/bin/libParquetWrapper64.solibcrypto.so.10: cannot open shared object file: No such file or directory

The file libParquetWrapper64.so exists in the correct OAS path, but the system is missing libcrypto.so.10. Our OS has a newer version of OpenSSL (1.1.x), and the system administrator created a symbolic link from libcrypto.so.10 to libcrypto.so.11. However, the Data Flow still fails (with new error: /lib64/libcrypto.so.10: version `libcrypto.so.10' not found), likely due to binary incompatibility between OpenSSL 1.0 and 1.1.

Can Oracle confirm whether compat-openssl10 is still a required dependency for Data Flows in OAS 2025, and if so, provide the recommended way to install it on newer Linux distributions that no longer include it by default?

    Hi,
    What is your OS? Is it in the list of supported systems for OAS 2025?

    If you want formal answers from Oracle about supported and certified environments, and libraries dependencies to not be running an unsupported system, you should consider raising a SR. The forum doesn't cover you in case of issues because your environment is found not certified.

    The solution + an alternative workaround is documented in the My Oracle Support knowledge base.Data Flows In Oracle Analytics Server (OAS) Are Failing With Error 'Query Failed: Unable To Load Dll :libcrypto.so.10' (Doc ID 3031219.1)
