Can not start dbca and sqlplus after 10gR2 installation on Z/Linux

After installed Oracle 10g and patched it to 10.2.0.4. I'm trying to create a database and getting the following errors:

[oracle@zLinux70 ~]$ dbcaWarning: JIT compiler "jitc" not found. Will use interpreter.UnsatisfiedLinkError exception loading native library: njni10Exception in thread "main" java.lang.UnsatisfiedLinkError: get at oracle.net.config.Config.getNetDir(Unknown Source) at oracle.net.config.Config.initConfig(Unknown Source) at oracle.net.config.Config.(Unknown Source) at oracle.sysman.assistants.util.NetworkUtils.(NetworkUtils.java:225) at oracle.sysman.assistants.util.step.StepContext.(StepContext.java:264) at oracle.sysman.assistants.dbca.backend.Host.(Host.java:686) at oracle.sysman.assistants.dbca.ui.UIHost.(UIHost.java:205) at oracle.sysman.assistants.dbca.ui.InteractiveHost.(InteractiveHost.java:54) at oracle.sysman.assistants.dbca.Dbca.getHost(Dbca.java:160) at oracle.sysman.assistants.dbca.Dbca.execute(Dbca.java:94) at oracle.sysman.assistants.dbca.Dbca.main(Dbca.java:180)

Then I tried sqlplus and also it's not working.
[oracle@zLinux70 ~]$ sqlplus /nologsqlplus: error while loading shared libraries: /u01/app/oracle/oracle/product/10.2.0/db_1/lib/libclntsh.so.10.1: cannot restore segment prot after reloc: Permission denied

By searching on Oracle support, I found the document
DBCA fails: UnsatisfiedLinkError exception loading native library: njni10 in z/Linux [ID 875013.1]. It says to disable SELinux.

Solution
Modify /etc/selinux/config file to set SELINUX=disabled as follows:

SELINUX=disabled.
SELINUXTYPE=targeted

The Linux admin had to bounce the server after the change.

[oracle@zLinux70 ~]$ /usr/sbin/sestatusSELinux status: disabled
[oracle@zLinux70 ~]$ /usr/sbin/getenforceDisabled

The issue is resolved after the bounce.
