Solution to oracle database file badELFinterpreter: Nosuchfileordirectory

Today is. If you encounter a lib problem today, record it again. This is a case and a process of solving the problem.

When we use sqlplus to log on to a unix database, problems such as: xxxxxx bad ELF interpreter: No such file or directory may occur. This problem is also caused by lib. The normal situation is as follows:

[root@dg1 ~]# su - oracle[oracle@dg1 ~]$ ldd `which sqlplus`        linux-vdso.so.1 =>  (0x00007fff2e5ff000)        libsqlplus.so => /u01/app/oracle/product/11.2.0/dbhome_1/lib/libsqlplus.so (0x00007fba1fef6000)        libclntsh.so.11.1 => /u01/app/oracle/product/11.2.0/dbhome_1/lib/libclntsh.so.11.1 (0x00007fba1d48b000)        libnnz11.so => /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 => /lib64/libc.so.6 (0x0000003c93c00000)        libaio.so.1 => /lib64/libaio.so.1 (0x00007fba1cea4000)        /lib64/ld-linux-x86-64.so.2 (0x0000003c93400000)[oracle@dg1 ~]$ 

But sometimes the corresponding lib file may be missing.

The solution to this problem is as follows:

1. Check which lib files are missing in the program

2. Check whether the corresponding lib file is missing or the environment variable.

3. If the lib file is missing, install the corresponding software package or copy the corresponding lib file. For environment variables, you need to set different environment variables for different systems.

In addition, for oracle, the 32-bit version is lib32, And the 64-bit version is the lib directory.

The following is an example of how to start RealSync today. Other programs are similar:

The following error is prompted when enabling Realsync:

dsg@dg2 scripts]$ ./start./start: /dsg/bin/archivelog: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory./start: /dsg/bin/archivelog: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory[dsg@dg2 scripts]$ ./stopINFO: Stop realsync normally...INFO: Stopping Vagentd ...INFO: Stopping Loader -s for fullsync loader ...INFO: Stopping Loader -r for realsync loader ...[dsg@dg2 scripts]$ [dsg@dg2 scripts]$ exit

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

[root@dg2 ~]# cd /media/OL6.4\ x86_64\ Disc\ 1\ 20130225/Packages/[root@dg2 Packages]# yum install glibc.i686Loaded plugins: refresh-packagekit, securityoel6                                                                                            | 3.7 kB     00:00 ...

It can be seen that there are two problems currently, one is libnnz. so does not exist, and the other is libclntsh. so.11.1 does not. You need to install the corresponding software package or directly copy the corresponding lib file to the corresponding directory.
Now, we need to modify the environment variables.
