Solaris 10 and Oracle 12c: the sqlplus client does not work

Hi all,

I try to run a Oracle12c sqlplus client on a Solaris 10 server. The DB is on a remote server.

This does not work, since the client expects a reference SUNWpublic in the library libc.so.1:

$ ldd sqlplus

        ...

        libc.so.1 (SUNWpublic) =>        (version not found)

        ...

The library itself is available and found in the LD_LIBRARY_PATH, but actually does not contain this reference:

$ pvs /usr/lib/sparcv9/libc.so.1

        libc.so.1;

        SUNW_1.23;

        SUNW_1.22.7;

        SUNW_1.22.6;

        ...

To compare, on a Solaris11 server this library contains the reference.

So I assume, either the client must not refer this library content or the library is not complete. The OS has already all available patches. The Oracle 12c is officially compatibel to Solaris10. Does anyone know about this problem or use this configuration?
