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.
Immediately after a successful ASM installation, ASMCMD will not start:
$ echo $ORACLE_HOME
$ export ORACLE_SID=+ASM
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.
