oratab populated, but 11G database doesn't start

user596857 Jul 21, 2009 11:09 PM

I've installed Oracle 11g on Redhat 5.
And created a database with dbca.
And set the oratab for it to start on boot.

But the database does not start on boot.

I noticed that there is more than one oratab file:

find / -type f -iname "oratab"

/etc/oratab
/oracle/oracle11/product/11.1.0/db_1/install/oratab

cat /etc/oratab

test:/oracle/oracle11/product/11.1.0/db_1:Y

The other file was empty:

ls -l /oracle/oracle11/product/11.1.0/db_1/install/oratab
-rwxr-xr-x 1 oracle11 dba 0 Jul 20 19:45 /oracle/oracle11/product/11.1.0/db_1/install/oratab

But I added the lines from the one file to the other.
And it still didn't come up when I rebooted.

Is 11G different from the previous versions?

What is the secret to getting the database to come up
automatically after rebooting the machine?

Thanks

Thanks. That was a start.
Now I'm getting issues with rsh.

The db didn't come up upon boot.
I ran the script manually, as root, and got:

/etc/init.d/dbora
+ ORACLE_HOME=/oracle/oracle11/product/11.1.0/db_1
+ ORACLE=oracle11
+ PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/oracle/oracle11/product/11.1.0/db_1/bin
++ hostname
+ HOST=bronze.gateway.2wire.net
++ uname
+ PLATFORM=Linux
+ export ORACLE_HOME PATH
+ '[' '!' '' = ORA_DB ']'
+ '[' Linux = HP-UX ']'
+ rsh bronze.gateway.2wire.net -l oracle11 /etc/init.d/dbora ORA_DB
connect to address 192.168.1.101 port 544: Connection refused
Trying krb4 rsh...
connect to address 192.168.1.101 port 544: Connection refused
trying normal rsh (/usr/bin/rsh)
bronze.gateway.2wire.net: Connection refused
+ exit
[root@bronze ~]# which rsh
/usr/kerberos/bin/rsh

Any ideas?

Thanks.

Hi,

By default, Red Hat Linux puts /usr/kerberos/bin at the head of the $PATH variable. This will cause the Kerberos version of rsh to be executed.

A workaround I typically use is to rename the kerberos version of rsh so that the normal rsh command will be used.

Do the following:

# su -

# which rsh
/usr/kerberos/bin/rsh

# mv /usr/kerberos/bin/rsh /usr/kerberos/bin/rsh.original
# mv /usr/kerberos/bin/rcp /usr/kerberos/bin/rcp.original
# mv /usr/kerberos/bin/rlogin /usr/kerberos/bin/rlogin.original

# which rsh
/usr/bin/rsh

Check if this workaround works for you also.

Cheers,

Marcello M.

user596857 Jul 22, 2009 5:01 PM (in response to 439075)

Thanks. I changed the file names, and rebooted.
But again the db did not come up.

which rsh
/usr/bin/rsh

Again I tried just running the script itself.

/etc/init.d/dbora
+ ORACLE_HOME=/oracle/oracle11/product/11.1.0/db_1
+ ORACLE=oracle11
+ PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/oracle/oracle11/product/11.1.0/db_1/bin
++ hostname
+ HOST=bronze.gateway.2wire.net
++ uname
+ PLATFORM=Linux
+ export ORACLE_HOME PATH
+ '[' '!' '' = ORA_DB ']'
+ '[' Linux = HP-UX ']'
+ rsh bronze.gateway.2wire.net -l oracle11 /etc/init.d/dbora ORA_DB
Permission denied.
+ exit

So, I tried to see if I could ssh into the server:

ssh bronze.gateway.2wire.net
The authenticity of host 'bronze.gateway.2wire.net (192.168.1.101)' can't be established.
RSA key fingerprint is cf:df:71:d4:ac:e2:a4:f1:42:cc:d6:ed:68:56:dd:81.
Are you sure you want to continue connecting (yes/no)? y
Please type 'yes' or 'no': yes
Warning: Permanently added 'bronze.gateway.2wire.net,192.168.1.101' (RSA) to the list of known hosts.
root@bronze.gateway.2wire.net's password:
Last login: Mon Jul 20 20:54:50 2009

- that worked.

And then tried to see if I could rsh into the server:

rsh bronze.gateway.2wire.net
Password:
Password:
Login incorrect

I think this part needs to work, not?
How can I get this part to work?

Thanks

ok! Sorry for asking...

In addition, the rsh daemon validates users using the /etc/hosts.equiv file or the .rhosts file found in the user's home directory.

In order to enable the "rsh" and "rlogin" services, you can follow below commands on both servers:
I did below test using two of my vmware.

# su -
# chkconfig rsh on
# chkconfig rlogin on
# service xinetd reload
Reloading configuration: [ OK ]

In order to allow the "tempusr1" UNIX user account for example to be trusted among the servers, I created the /etc/hosts.equiv file on both servers:

# su -
# touch /etc/hosts.equiv
# chmod 600 /etc/hosts.equiv
# chown root.root /etc/hosts.equiv

Now I added all servers to the /etc/hosts.equiv file similar to the following example for both servers:

# cat /etc/hosts.equiv
+vmlinux_node01 tempusr1
+vmlinux_node02 tempusr1

Testing...
# su - tempusr1

$rsh vmlinux_node01 ls -l /etc/hosts.equiv
-rw------- 1 root root 78 Jul 22 15:06 /etc/hosts.equiv

$rsh vmlinux_node02 ls -l /etc/hosts.equiv
-rw------- 1 root root 78 Jul 22 15:06 /etc/hosts.equiv

Thanks.

I did the following. Some luck.
But still, the DB startup script is not working.

cat /etc/hosts.allow
#
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
bronze

bronze.gateway.2wire.net

I added a file for root also:

cat /root/.rhosts
#
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
bronze

bronze.gateway.2wire.net

And for oracle11:

cat /home/oracle11/.rhosts
#
# hosts.allow This file describes the names of the hosts which are
# allowed to use the local INET services, as decided
# by the '/usr/sbin/tcpd' server.
#
bronze

bronze.gateway.2wire.net

which tcpd
/usr/sbin/tcpd

-------------

su - root
chkconfig rsh on
chkconfig rlogin on
service xinetd reload
Reloading configuration: [ OK ]

touch /etc/hosts.equiv

ls -l /etc/hosts.equiv
-rw-r--r-- 1 root root 0 Jul 22 11:43 /etc/hosts.equiv

chmod 600 /etc/hosts.equiv
chown root.root /etc/hosts.equiv

edit /etc/hosts.equiv

cat /etc/hosts.equiv

+bronze                     root
+bronze.gateway.2wire.net   root

+bronze                     oracle11
+bronze.gateway.2wire.net   oracle11

reboot:

I can login as oracle11.
But it won't allow me to login as root.

If I'm logged in as oracle11:

[oracle11@bronze ~]$ rsh bronze
Last login: Wed Jul 22 12:23:57 on :0

[oracle11@bronze ~]$ rsh bronze.gateway.2wire.net
Last login: Wed Jul 22 12:28:32 from bronze

It doesn't even ask for the password.

If I'm logged in as root:

rsh bronze.gateway.2wire.net
Password:
Password:
Login incorrect

login: root
Password:
Login incorrect

login: oracle11
Password:
Last login: Wed Jul 22 12:28:59 from bronze

as oracle11:

rsh bronze ls -l /etc/hosts.equiv
-rw------- 1 root root 143 Jul 22 12:09 /etc/hosts.equiv

However, again the script is not working.

[root@bronze ~]# /etc/init.d/dbora
+ ORACLE_HOME=/oracle/oracle11/product/11.1.0/db_1
+ ORACLE=oracle11
+ PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin:/oracle/oracle11/product/11.1.0/db_1/bin
++ hostname
+ HOST=bronze.gateway.2wire.net
++ uname
+ PLATFORM=Linux
+ export ORACLE_HOME PATH
+ '[' '!' '' = ORA_DB ']'
+ '[' Linux = HP-UX ']'
+ rsh bronze.gateway.2wire.net -l oracle11 /etc/init.d/dbora ORA_DB
bash: /etc/init.d/dbora: Permission denied
+ exit

Is there something wrong with the script?

Hi,

bash: /etc/init.d/dbora: Permission denied
According to the link provided earlier we have:

5 - Change the group of the dbora file to the OSDBA group (typically dba), and set the permissions to 750:

# chgrp dba dbora
# chmod 750 dbora

Do you have right permissions?

Good one! That worked!

I'd made the file in the /home/ oracle11 home directory, and then copied it over.
The permissions were correct.
But the group ownership must have changed then.

Thanks a lot!
