Samba CIFS mounts and securing user password

October 15, 2017 Leave a comment

Adding the code blocks below to /etc/rc.local:

mount.cifs //<host1>/share /<mount_point> -o ro,credentials=/root/.cifs.<host1>,remount

Option “remount” prevents double mounting of the same share.

File .cifs.<hostname> contains:

user=<user>
password=<password>
domain=<domain>

Vagrantfile

Working vagrantfile I want to keep as a sample template:

 

# -*- mode: ruby -*-
# vi: set ft=ruby :
VAGRANTFILE_API_VERSION = “2”
Vagrant.require_version “>= 1.7.2”

# All Vagrant configuration is done below. The “2” in Vagrant.configure
# configures the configuration version. Please don’t change it unless you know what
# you’re doing.
Vagrant.configure(2) do |config|

config.vm.box = “<user>/openshift-origin”
#uncomment this line if you downloaded the box and want to use it instead
#config.vm.box = “openshift3”
config.vm.box_check_update = false
config.vm.network “private_network”, ip: “10.2.2.2”
config.vm.synced_folder “.”, “/vagrant”, disabled: true
config.vm.hostname = “origin”
# Create a forwarded port mapping which allows access to a specific port
# within the machine from a port on the host machine. In the example below,
# accessing “localhost:8080” will access port 80 on the guest machine.
# config.vm.network “forwarded_port”, guest: 80, host: 8080
#config.vm.network “forwarded_port”, guest: 80, host: 1080

Finding exact SCNs for Oracle Incomplete Restore

Using reference from goldparrot below really helped:
https://goldparrot.wordpress.com/2011/05/16/how-to-find-exact-scn-number-for-oracle-restore/

2) Get the greatest of either absolute_fuzzy_change# or checkpoint_change# for your datafile backups.

The quickest way to roll forward just beyond the backup to open resetlogs is
to query v$backup_datafile.
You then just need to choose the greatest of either the absolute_fuzzy_change# or checkpoint_change#
for your backupset.

You can modify the query to your liking, and even add in many details from stamp and recid, but below
gets the job done quickly. Just choose the day in which your level0 or level1 completed and modify appropriately.

=============================================
` col fuzz# format 99999999999999999999999999
` col chkpnt# format 99999999999999999999999999

select max(absolute_fuzzy_change#) fuzz#, max(checkpoint_change#) chkpnt# from
(select file#, completion_time, checkpoint_change#, absolute_fuzzy_change# from v$backup_datafile
where incremental_level = 0
and trunc(completion_time) = to_date(‘JUN-20-2010′,’MON-DD-YYYY’)
and file# <> 0
order by completion_time desc
);
===============================================

This will return 2 SCN numbers. Pick the greatest of the 2.

FUZZ# CHKPNT#
