VMWare Orientation
•Desktop Products
 –VMWare Workstation: “Full” product $
  VMWare               Full product,
 –VMWare Player: Free, no creation, just use
•Server Products
 Server
 –VMWare Infrastructure (ESX Server): $$$,
  robust, clustering capable, OS replacement
         ,         g p      ,      p
 –VMWare VirtualCenter: $$, management
  tool for whole environment, Windows
 –VMWare Server: free, limited, on top of OS


                                               4
VMWare Server Hardware
•Almost any server will do, mine is:
 –Dell SC440: 1 x dual-core 3.0 Ghz
 –2 x 500Gb internal SATA drives, using LVM
 –4 Gb RAM
•I use Linux (OEL 5) as host OS
•Let Linux use LVM (default), allows disk
 space to be pooled for 900+ Gb on /u01
                        900
•VMWare Server 1.0.5
•Two Virtual Networks: 1 bridged & 1 host-
                             g
 only

Install Node1 OS
•Plan the network addresses for public and
 private networks
•Start the VM and the CD image should boot
•Install the OS ensuring enough swap and
             OS,
 /tmp
•Assign static addresses t each i t f
 A i       t ti dd       to   h interface
•See whitepaper for package and setup
 details
 d t il


                                         24
Post-Install Steps on Node1
•Modify /etc/hosts
•Set kernel parameters
 Set
•Set limits in /etc/security/limits.conf
•Add groups (oinstall, dba), oracle user
•Set up oracle user’s profile (shell limits,
 Set             user s
 ORACLE_BASE)
•Set up SSH user equivalency


                                               25
Prerequisite Checking
•Most issues arise from misconfiguration
 of OS, packages networks or storage
    OS packages, networks,
•Tools exist to help check prerequisites
 –CVU
  CVU
 –RDA
•Some basic networking knowledge helps
•Recipes can help, be sure y
     p          p,          you
 understand why, not just follow steps


                                           26
Prerequisite Checking - RDA
•Metalink Note 314422.1 will orient you to
 the RDA and has links for download
•Download the .zip file, unzip and run (as
 root or oracle):
 –./rda.sh –T hcve
 –provide the release you want to check
 –answer additional questions
 –obtain results in ./output/RDA* files

Node1: Add Shared Storage
•Shut down guest OS in Node1
•On the VMWare ser er host OS create
 On               server      OS,
 a new directory for shared disk files:
mkdir –p /u01/vmware/vms/rac disks
       p /u01/vmware/vms/rac-disks
•Back at the VMWare Server Console,
 add new disks to the Node1 (RAC1) VM

•Now for the tricky part: hand-editing
 VMWare configuration filefile.
•The changes we make enable the disks
 to be shared with other VMs
                           VMs.
•Add or update the following parameters
 in the “/u01/vmware/vms/RAC1/Red

Prerequisite Checking - CVU
•Finally able to complete more
 prerequisite checking
•As the oracle user, run CVU to confirm
 private networking and user
         networking,
 equivalence:
./cluvfy stage –post h
 / l f    t        t hwos –n rac1,rac2
                                1    2




                                          52
53
Prerequisite Checking - CVU
•Shared storage checks don’t work on
 VMWare since the disks do not support
 SMART (used by CVU to verify disk
 accessibility)
•Next, check the pre-crsinst stage like this:
./cluvfy –pre crsinst –n rac1,rac2 
 / l f           i t        1    2
 –r 11gR1

Common Issues #1: Firewalls
•Firewall and SELinux should be disabled
•Can be done d ring install with some
 Can           during            ith
 versions of Linux. If not, then…
•Set SELINUX=disabled i
 S t                          in
 /etc/sysconfig/selinux
•chkconfig iptables off
•Reboot
 Reboot



                                       124
Common Issues #2: Storage
•Shared Storage misconfiguration –
 different names for disks on each node
•For RHEL or OEL 5, use udev for
 privileges and device mapping
•Note Linux v4 and v5 handle things
 differently
•Ensure you use proper device in
 multipath configurations (not applicable
 in VMWare)


                                            125

Common Issues #3: Networking
•Networking, especially private network,
 must be configured properly
•NO CROSSOVER CABLES ALLOWED!
•In VMWare ensure you use correct
    VMWare,
 interface for public, private networks
•Use h t l network f private, bridged
 U host-only t          k for i t b id d
 for public
•Set up b di b f
 S t     bonding before i t lli clusterware
                           installing l t


                                         127
Common Issues #4: Filesystems
•Don’t “go nuts” with Linux filesystem
 layout
•Avoid too many filesystems (especially
 on a test system)
•Ensure you create sufficient swap space




                                       128
Common Issues #5: Host equivalency

•Don’t hate SSH, just set it up properly!
ssh-keygen t
ssh keygen –t dsa
cat ~/.ssh/id_dsa.pub >> 
 ~/.ssh/authorized_keys
  /      /
scp –rp ~/.ssh othernode:.
ssh <remote_node> date
