Summary

of

Changes

The

following

new

functionality

has

been

added

to

version

1.2.10

of

DP

for

ESS

for

mySAP.com

Technology

for

Oracle

(hereafter

’DP

for

ESS’):

v

Support

for

the

SAP

″SPLITINT

Interface

for

Oracle″.

The

older

″Split

Mirror

Backup″

interface

and

the

Shortened

Backup

Processing

Feature

(SBPF)

are

no

longer

supported.

The

functionality

of

both

is

integrated

into

the

new

interface,

and

the

DP

for

ESS

program

’idscntl’

has

therefore

been

renamed

to

’splitint’.

Note:

For

existing

installations

upgrading

to

DP

for

ESS

1.2.10:

In

conjunction

with

the

above

program

name

change,

the

parameters

’split_cmd’

and

’resync_cmd’

have

effectively

been

deleted

and

two

new

parameters,

split_options

and

split_resync,

have

been

introduced.

The

required

migration

associated

with

these

changes

is

described

in

Appendix

E,

“Migration

from

Previous

DP

for

ESS

Releases,”

on

page

247.

v

Support

for

FlashCopy

restore

(also

known

as

FlashBack

Restore).

To

support

the

FlashBack

Restore,

a

new

FCS_FILE

parameter

has

been

introduced

for

DP

for

mySAP.com.

v

Employ

selected

FlashCopy

V2

functionality:

–

incremental

FlashCopy

(see

“Incremental

FlashCopy

Backup

and

Restore”

on

page

6

–

FlashCopy

across

different

logical

subsystems

(eliminates

an

ESS

volume

setup

restriction)

Existing

functionality

has

been

changed

(’unmount’

function)

and

extended

with

the

new

’split’

(formerly

’flashcopy’)

and

’resync’

functions.

Additional

changes:

v

A

capability

for

a

″diskonly″

FlashCopy

Backup

is

provided.

v

Added

a

new

command

(tdpessora)

to

provide

information

for

the

restore/recovery

process.

v

Increased

the

range

of

supported

platforms

to

include

AIX

5.2,

and

deleted

AIX

4.3.3

as

a

supported

platform.

v

Added

a

paragraph

listing

environments

that

are

not

supported

(see

“Environment

Requirements”

on

page

31).

v

Changes

in

setup

requirements:

–

all

volume

groups

of

the

production

system

containing

ESS

volumes

must

be

set

up

with

vpaths

if

SDD

is

installed

(see

“Aspects

of

Using

the

Introduction

Data

Protection

for

IBM

ESS

for

mySAP.com

Technology

(hereafter

DP

for

ESS)

minimizes

the

impact

on

mySAP.com

Oracle

database

servers

while

allowing

automated

database

backups

to

the

Tivoli

Storage

Manager

Server.

Integrated

in

the

mySAP.com

DBA

tools2,

DP

for

ESS

off-loads

the

transfer

of

backup

data

from

the

database

server.

The

Oracle

database

must

reside

on

an

ESS

storage

subsystem.

DP

for

ESS

V1R1

provides

options

to

implement

high-efficiency

backup

and

restore

of

business-critical

databases,

while

virtually

eliminating

backup-related

downtime

or

user

disruption

on

the

production

host

and

significantly

reducing

database

restore

time.

Understanding

DP

for

ESS

This

section

describes

the

operating

environment

and

functions

of

DP

for

ESS.

Operating

Environment

The

operating

environment

consists

of

the

Oracle

DBMS

executing

on

an

AIX

server

attached

to

an

IBM

Enterprise

Storage

Server

(ESS).

This

AIX

server

is

the

production

system.

Another

AIX

server,

the

backup

system,

is

also

attached

to

the

same

ESS

to

back

up

ESS

FlashCopy

copies

of

the

production

system

to

the

Tivoli

Storage

Manager

server.

This

is

done

by

the

concerted

action

of

the

programs

of

the

products

mySAP.com

DBA

tool

(brbackup),

DP

for

ESS

(splitint),

and

Data

Protection

for

mySAP.com

Technology

(backint/prole).

As

of

DP

for

ESS

version

1.2.5

and

DP

for

mySAP.com

(3.3.10),

it

is

possible

to:

v

suppress

the

backup

of

the

files

on

the

FlashCopy

disk

copies

to

the

Tivoli

Storage

Manager

server

(disk-only

backup)

in

order

to

accelerate

the

backup

process

v

allow

a

restore

from

the

FlashCopy

copies

to

the

database

disks

of

the

production

system

(FlashBack

Restore)

To

facilitate

the

control

of

disk-copy

backups

as

well

as

the

restore

of

disk

copies

with

DP

for

ESS

1.2.10,

a

new

component

(tdpessora)

and

sample

scripts

(PreRestore.sh

and

PostRestore.sh)

have

been

introduced.

DP

for

ESS

requires

Data

Protection

for

mySAP.com

Technology

(hereafter

DP

for

mySAP.com)

in

order

to

v

perform

the

actual

backup

or

restore

to

or

from

the

Tivoli

Storage

Manager

server

v

call

DP

for

ESS

for

a

Flashback

Restore.

Guide

for

Oracle

Once

brbackup

(on

the

backup

system

)

has

been

started

with

the

parameters

to

do

a

FlashCopy,

it

will

first

interact

with

the

Oracle

DB

on

the

production

system

via

SQLNET

to

get

the

Oracle

DB

information

and

then

call

DP

for

ESS,

which,

with

its

components

(CORE,

IDS,

and

LVM),

will

ensure

that

brbackup

will

get

all

the

volumes

(IBM

ESS

target

volumes)

with

the

files

brbackup

needs

to

run

a

full

Oracle

DB

backup.

brbackup

will

also

ensure

the

backup

of

certain

profiles

and

control

files

of

the

production

system

that

will

be

accessed

on

the

backup

system

via

NFS.

When

performing

the

backup,

brbackup

will

call

DP

for

mySAP.com

to

perform

the

actual

backup.

brbackup

normally

runs

as

a

batch

job;

however,

as

with

other

SAP

DBA

tools,

it

can

also

be

called

as

a

function

within

the

interactive

tool

sapdba.

Restore

of

a

complete

DB

will

be

done

interactively

by

running

brrestore

on

the

production

system,

which

will

call

DP

for

mySAP.com

(backint)

to

interface

with

DP

for

ESS,

calling

the

’flashback’

function

if

requested.

Role

of

splitint

The

’split’

function

of

splitint

can

be

used

by

brbackup

for

FlashCopy

operations;

there

are

other

functions

(such

as

unmount,

withdraw,

password,

and

inquire)

that

can

be

requested

when

calling

splitint

as

a

command

not

under

control

of

brbackup.

Optionally,

after

the

call

for

the

backup

has

completed,

brbackup

can

call

the

resync

function

of

splitint

to

perform

resynchronization.

splitint

is

structured

in

3

component

layers:

CORE,

LVM,

and

IDS.

The

CORE

component

has

the

following

tasks:

v

acts

as

a

direct

interface

to

brbackup

v

reads/checks

the

DP

for

ESS

profile

v

performs

environment

checks

v

performs

housekeeping

functions

for

–

handling

temporary

and

permanent

files

containing

information

for

the

other

components

used

in

the

various

stages

in

one

functional

run

or

in

subsequent

functional

runs

(these

files

will

reside

in

NFS

directories)

–

functions

When

first

introduced,

DP

for

ESS

was

primarily

designed

based

on

the

requirements

of

the

SAP

″split-mirror″

architecture.

This

allowed

brbackup

and

idscntl

(the

predecessor

of

splitint)

to

create

FlashCopy

copies

and

the

files

with

those

copies

to

be

backed

up

to

a

Tivoli

Storage

Manager

server.

The

lack

of

an

interface

in

this

architecture

for

restoring

the

FlashCopy

copies

back

to

the

database

disks

of

the

production

system

has

been

resolved

with

an

interface

between

DP

for

mySAP.com

(starting

with

version

3.3.10)

and

DP

for

ESS

with

splitint

(starting

with

version

1.2.10).

High-Availability

Oracle

Database

Backup

Using

ESS

Flashcopy

Volumes

DP

for

ESS

accomplishes

high-availability

backup

of

an

Oracle

database

on

an

Enterprise

Storage

Server

by

using

FlashCopy

devices.

DP

for

ESS,

a

co-product

of

DP

for

mySAP.com,

integrates

with

the

Enterprise

Storage

Server

FlashCopy

volumes

to

allow

the

high-performance,

database-aware

FlashCopy

backups

of

Oracle

databases

on

a

secondary

host

machine

(also

referred

to

in

this

document

as

the

backup

system)

while

the

production

application

remains

online

and

fully

available

to

users.

While

DP

for

ESS

initiates

the

FlashCopy

operation,

creating

target

volumes

from

the

source

volumes

of

the

production

database

and

making

target

volumes

and

file

systems

on

the

secondary

host

machine

(backup

system)

available,

DP

for

mySAP.com

can

back

up

the

FlashCopy

volumes

there.

Because

the

backup

operation

is

conducted

from

the

FlashCopy

disk

copy

(target

volumes)

4,

most

processing

occurs

on

the

backup

system.

As

a

result,

the

inaccessibility

of

the

production

database

is

minimized

and

the

production

host

continues

to

dedicate

processor

time

to

the

production

database.

This

greatly

reduces

any

performance

impact

on

the

production

database

server.

DP

for

ESS

works

on

requests

(split

and,

optionally,

resync,

which

will

result

in

an

ESS

FlashCopy

and

optionally

unmount/withdraw)

from

the

mySAP.com

DBA

tool

brbackup.

The

actual

backup

is

the

term

″split-mirror″

backup

is

used

to

request

a

High-Availability

Oracle

Database

Restore

Using

ESS

FlashCopy

DP

for

ESS

accomplishes

high-availability

restores

of

an

Oracle

database

on

an

Enterprise

Storage

Server

by

using

ESS

FlashCopy

devices.

The

program

uses

the

ESS

FlashCopy

volumes

of

a

previously

taken

FlashCopy

Backup

to

allow

the

high-perfoce,

database-aware

FlashCopy

Restore

of

Oracle

databases

on

the

production

system

in

case

of

production

system

failure.

While

DP

for

ESS

initiates

the

FlashCopy

Restore

operation,

the

production

system

will

be

cleaned

up

(all

DB

file

systems

will

be

unmounted,

all

DB

volume

groups

will

be

exported).

After

the

cleanup,

splitint

will

initiate

the

FlashCopy

from

the

target

volumes

(from

a

previously

taken

FlashCopy

backup)

to

the

production

system

source

volumes.

Then,

all

DB

volume

groups

will

be

imported

and

all

DB

file

systems

re-mounted.

The

DB

recovery

and

production

work

need

not

wait

for

the

completion

of

the

ESS

background

copy

initiated

by

DP

for

ESS.

This

greatly

reduces

the

downtime

of

the

production

database

server.

Depending

on

the

installed

ESS

microcode

level,

an

ESS

FlashCopy

with

COPY

or

INCR

(incremental)

will

be

used

for

the

restore

(see

“Installation

Requirements”

on

page

29

for

details).

Incremental

FlashCopy

Backup

and

Restore

DP

for

ESS

now

allows

controlled

disk-copy

backups

of

an

Oracle

database

using

the

Enterprise

Storage

Server

Incremental

FlashCopy

feature.

This

feature

makes

it

possible

to

perform

a

background

copy

between

the

ESS

source

and

target

volumes

without

having

to

copy

all

the

tracks

in

the

process.

This

results

in

improved

perfoce

for

the

Oracle

Servers

that

are

configured

to

the

ESS.

Incremental

FlashCopy

applies

only

to

the

storage

hardware

level

copy

(the

FlashCopy

made

between

the

ESS

source

and

target

volumes).

It

does

not

apply

to

the

application

level

copy

(the

backup

copy

of

the

database

to

the

Tivoli

Storage

Manager

Server).

An

incremental

FlashCopy

(see

’RMAN

interface’

on

page

16)

cannot

be

performed

when

the

entire

Oracle

database

is

backed

up

to

the

Tivoli

Storage

Manager

Server.

An

incremental

FlashCopy

backup

is

invoked

with

the

value

INCR

for

the

FLASHCOPY_TYPE

in

the

DP

for

ESS

profile

(.fcs).

FLASHCOPY_TYPE

Value”
