pam.d and Oracle 11g1 failure FIXED but what about errors



Oracle 11g1 automatic startup under Fedora 9 Linux worked for months
Then in late 3/2009 I had to start 11g1 manually!                   

I've do regular yum updates.

currently :
Able (root) /var/log 600>uname -a
Linux Able 2.6.27.19-78.2.30.fc9.i686 #1 SMP Tue Feb 24 20:09:23 EST 2009 i686 i686 i386 GNU/Linux

on boot page, the usual command that starts 11g1 just zips on by

How it should be done..this worked before 3/2009
http://download.oracle.com/docs/cd/B28359_01/server.111/b32009/strt_stp.htm#sthref191

I've looked in all the boot messages to no avail. I did find the messages below in
/var/log/secure below                                                              

I suspected pam.d and I was right!

SELINUX is disabled as a site suggested!

I changed /etc/pam.d/rsh to the following and now Oracle 11g1 is starting automatically again:

#%PAM-1.0
# For root login to succeed here with pam_securetty, "rsh" must be
# listed in /etc/securetty.                                       
auth required pam_nologin.so                                      
auth required pam_securetty.so                                    
auth required pam_env.so                                          
# auth sufficient pam_rhosts.so                                   
auth sufficient pam_rhosts_auth.so                                
account include system-auth                                       
session optional pam_keyinit.so force revoke                      
session include system-auth                                       
session required pam_loginuid.so                                  

I did a www.ask.com for "dbstart pam.d" and got the answer.

I am still wary of lurking problems!
