ASMCMD fails to start on module libnnz10.so, permission denied (Doc ID 790470.1)

Last updated on MARCH 17, 2009

Applies to:

Oracle Server Enterprise Edition - Version: 11.1.0.6 to 11.1.0.7
This problem can occur on any platform.
ASM - Version: 11.1.0.6 to 11.1.0.7
Red Hat Advanced Server
Linux x86-64
RHEL 5 and OEL 5 only. RHEL 4 and OEL 4 are not affected. This is because of the more aggressive way that SELinux policies are enforced in RHEL 5 and OEL 5.

Symptoms

Immediately after a successful ASM installation, ASMCMD will not start:

$ echo $ORACLE_HOME
/opt/oracle/10.2.0
$ export ORACLE_SID=+ASM
$ asmcmd
install_driver(Oracle) failed: Can't load '/opt/oracle/10.2.0/perl/lib/site_perl/5.8.3/i686-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: /opt/oracle/10.2.0/lib32/libnnz10.so: cannot restore segment prot after reloc: Permission denied at /opt/oracle/10.2.0/perl/lib/5.8.3/i686-linux-thread-multi/DynaLoader.pm line 229.
at (eval 2) line 3
Compilation failed in require at (eval 2) line 3.
Perhaps a required shared library or dll isn't installed where expected
at /opt/oracle/10.2.0/bin/asmcmdcore line 5953

Changes

SELINUX policy "Enforcing" causes the permission problem.
