Mount the CD/DVD:  mount /dev/cdrom /mnt/cdrom

Then trick the baseurl directives to point to the file instead of Oracle’s public yum server in the /etc/yum.repos.d/public-yum-ol6.repo/public-yum-el5.repo or /etc/yum.repos.d/public-yum-ol6.repo file:

[root@ovmanager media]# mount /dev/cdrom /mnt

mount: block device /dev/sr0 is write-protected, mounting read-only
 
[oracle@ovmanager yum.repos.d]$ pwd
/etc/yum.repos.d
 
[oracle@ovmanager yum.repos.d]$ vi public-yum-el5.repo
 

[ol5_u8_base]

name=Oracle Linux $releasever Update 8 installation media copy ($basearch)
baseurl=file:///mnt/OL5.8/Server/
gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5

Now you are ready to install packages from your local yum repository

For those who are interested in knowing how to determine HBA port id (world-wide name – WWN) from a Linux box, see below. Note is this is for RHEL/OEL 6.x. 5.x is quite different. In our case its simple, we have one HBA, but the following can be used to walk thru it:

 
#lspci | grep -i fibre

03:00.0 Fibre Channel: QLogic Corp. ISP2432-based 4Gb Fibre Channel to PCI Express HBA (rev 02)
 
#systool -av -c fc_host
 
 
Class Device = "host6"
  Class Device path = "/sys/devices/pci0000:00/0000:00:1c.0/0000:03:00.0/host6/fc_host/host6"
    dev_loss_tmo        = "45"
    fabric_name         = "0xffffffffffffffff"
    issue_lip           = <store method only>
    max_npiv_vports     = "127"
    node_name           = "0x200000e08b93a654"
    npiv_vports_inuse   = "0"
    port_id             = "0x000000"
    port_name           = "0x210000e08b93a654"
    port_state          = "Linkdown"
    port_type           = "Unknown"
    speed               = "unknown"
    supported_classes   = "Class 3"
    supported_speeds    = "1 Gbit, 2 Gbit, 4 Gbit"
    symbolic_name       = "QLE2460 FW:v5.03.07 DVR:v8.04.00.08.39.0-k"
    system_hostname     = ""
    tgtid_bind_type     = "wwpn (World Wide Port Name)"
    uevent              = 
    vport_create        = <store method only>
    vport_delete        = <store method only>
 
Thus WWN == 20:00:00:e0:8b:93:a6:54

First task performed was to install RPMs, set kernel params and other OS configurations leveraging oracle’s oracle-rdbms-server-11gR2-preinstall package.

Second, we need to change the security limits for soft files to 8192 from 1024

# oracle-rdbms-server-11gR2-preinstall setting for nofile soft limit is 1024
oracle soft nofile 8192

Then perform the installation:

Starting from Oracle Database 11g Release 2, we no longer use the oracle-validated install.  Instead, we are supposed to leverage the new oracle-rdbms-server-11gR2-preinstall instead.

cat dg_tar.ksh
tar cpfX - dg.exclude dgmenu > dg.tar
 
$ cat dg.exclude
dgmenu/old
dgmenu/conf
dgmenu/log
afiedt.buf
*.old
*.bkup

Notes:
1. dgmenu is the directory that we are creating a tar-ball for
2. c – create a new archive containing the specified items (in this case excluding the contents of dg.exclude criteria)
3. f – the name of the archive file to create
4. p – preserve file permissions


Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backups [ID 1389592.1]

What does this mean?  It means we can perform migrations from AIX/Solaris/HP-UX to Linux with significantly reduced downtime.  I can perform incremental backups across endianness.

This was originally tested for the Exadata and now it is available for everyone.

From time to time, customers ask if we can delay apply of archive logs on the standby database(s).  I tell them absolutely but MAA best practice is to setup flashback recovery area and enable database flashback on both the primary and physical standby databases.  In addition to enabling flashback, some customers are still persistent about delaying the apply on the physical standby database.  In physical standby, we can delay redo apply in one of two ways:

1.  alter database recover managed standby database using current logfile DELAY 30 disconnect;

2.  alter system set log_archive_dest_2=’SERVICE=###_PRIMARY_DATABASE_###_STDBY lgwr async reopen=30 delay=30 ….’ 

The delay attribute specifies that the archive logs are not available for recovery until the delay time interval has expired.  The delay option specifies the lag between when redo data is archived on a standby site and when the archived redo log file is applied to the standby database.  Important thing to note is that the delay does not impact the transmit time to the standby site.

For those interested in the clonedb feature of Oracle Direct NFS, check out MOS:  Clone your dNFS Production Database for Testing [ID 1210656.1]

On the ZFSSA, we have the ability to create snapshots and offer clones of our snapshots.  From a ZFSSA perspective, it is extremely simple to create snapshots and clones of snapshots via the BUI or CLI.    For customers with Exadata and ZFSSA, we obviously have options.  We can experiment with clonedb or leverage the storage appliance technology.

As a DBA, you may want to have the control yourself, especially, if you do not have control over the filer.  Check out this post by Kevin Closson.  He does a great job introducing the concept and showing you how to do it.   If you read to the end of his post, he provides links to couple of great videos on youtube.
