Oracle Library file resolution bad ELF interpreter:no such file or directory

Today is 2014-05-27, today encountered a Lib problem, record again. This is a case, but also a way to solve the problem of the process.

When we use Sqlplus to log in to a UNIX database, there is a possibility of a similar problem: xxxxxx bad ELF interpreter:no such file or directory. The cause of this problem is also the problem of Lib. The normal situation is as follows:

[Email protected] ~]# su-oracle[[email protected] ~]$ ldd ' which sqlplus ' linux-vdso.so.1 = (0x00007fff2e5f f000) libsqlplus.so =/u01/app/oracle/product/11.2.0/dbhome_1/lib/libsqlplus.so (0x00007fba1fef6000) Lib clntsh.so.11.1 =/u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1 (0x00007fba1d48b000) libnnz11.s o =/u01/app/oracle/product/11.2.0/dbhome_1/lib/libnnz11.so (0x00007fba1d0be000) libdl.so.2 =/LIB64/LIBDL. So.2 (0x0000003c93800000) libm.so.6 =/lib64/libm.so.6 (0x0000003c94400000) libpthread.so.0 =/lib64 /libpthread.so.0 (0x0000003c94000000) libnsl.so.1 =/lib64/libnsl.so.1 (0x0000003ca3000000) libc.so.6 =& Gt /lib64/libc.so.6 (0x0000003c93c00000) libaio.so.1 =/lib64/libaio.so.1 (0x00007fba1cea4000)/lib64/ld-li Nux-x86-64.so.2 (0x0000003c93400000) [[email protected] ~]$

However, sometimes the corresponding lib file may be missing.

So the solution to this problem is:

1, see the program is missing LIB files are those

2, to determine the corresponding LIB file is missing or environment variable problem.

3, if the Lib file is missing then need to install the corresponding package or copy the corresponding lib file. In the case of environmental variables, it is necessary to set different environment variables for different systems.

Also for Oracle we install the 32-bit is the LIB32, is the 64-bit then the Lib directory.

Here is an example of a startup RealSync I have encountered today, similar to other programs:

Start RealSync Prompt for the following error:

Then for ld-linux.so.2 is the corresponding glibc.i686 this package. So the installation is as follows:

This is no error prompt, check the log as follows:

You can know that there are two problems, one is libnnz.so no, the other is libclntsh.so.11.1 not. What needs to be done is to install the corresponding software package or copy the corresponding LIB file to the corresponding directory directly.
The thing to do now is to modify the environment variable
