What if the Following were True During Patching
• Critical business operations were not interrupted by maintenance operations
• Revenue generating activities were to stay online
– Web Orders
– Booking Orders
– Service Requests
• Business users were to stay online
– Pay Suppliers
– Pay Employees
– Uninterrupted manufacturing operations
• Downtime required by any patch was predictable
– Measured in minutes not days or hours
• Global Single Instances remained operational 24*7
– Maintenance window easier to allocate as shorter time required

Online Patching
• In 12.2 all patching operations are online
– EBS will remain available to users during patching operations
• Different lines of Business are no longer affected by patching
– Run Financials while applying an HR legislative updates
– Run Manufacturing while applying Financials updates
E-Business Suite Remains Online During Patching

Copy the Code, NOT the Data
• EBS uses both the file system and the database to store the code and data
that make up the application
– Code
• Stored both on the File system & In the Database
• Any code object changed in a patch is copied
– Data
• Stored both on the File system & In the Database
• Application data is NOT copied by a patch

Downtime Redefined as “Cutover”
• Cutover is the time taken to switch users from the production system to
the newly patched copy
• Cutover changes the unit of measure for downtime
– Measured in minutes NOT hours or days
• Cutover time is very predictable
– The time taken to bounce the Middle Tiers
Changing the Unit of Measure for Downtime

Downtime Limited to Short Cutover
• Users are logged off the production Instance
• When users reconnect they are directed to the newly patched system

Production Patched Production

• Downtime Patches
– No online users
– Wall clock time very important
– Consumes all resources
– Upgrade designed to run as fast as
possible
• Online Patches
– User remain online
– Wall clock time is no longer an
overriding concern
– Online users share resources
– Data upgrades designed to not affect
the running application
Changing the Patching Paradigm

Patching Occurs on a Copy
• File system Patching
–All patches are applied to a secondary file system
–Synchronization of the file systems is managed by the patching tools
• Database Patching
–A separate copy is maintained of all database code objects that are
changed by a patch
–Utilizes Edition-Based Redefinition feature of the Database

File System Editioning

• Run file system
– Used by online users
– Stores a complete copy of all
Applications and Middle Tier
code
– Logically mapped to either
fs1 or fs2
• Patch file system
– Used by patching tools
– Stores a complete copy of all
Applications and Middle Tier
code
– Logically mapped to either
fs1 or fs2
• Non-Editioned file system
– Used for data files
e.g.: data import/export files,
log files, report output files
– Only stores data files
Online Patching uses a Dual File System
fs1 and fs2 switch Run and Patch designation during the cutover phase of an Online Patching cycle

R12.2 Environment Overview
• New script to setup the environment: EBSapps.env RUN | PATCH
• New environment variables for R12.2 to help you navigate the system
$FILE_EDITION - Current fs edition type sourced, values: run or patch
$RUN_BASE - RUN file system base directory
$PATCH_BASE - PATCH file system base directory
$NE_BASE - Non-edition file system base directory
$APPL_TOP_NE - Application top that stores product files considered data
$PATCH_TOP – Directory where the patch files are unzipped
– On a multi-node system with non-shared file systems, you must copy the patch files to each
separate $PATCH_TOP directory, so that the patch files are available from the same location on all
nodes

– Patch Edition - Either:
• Currently being patched
or
• Waiting for the next patching cycle
– The two files systems are rotated between Run and
Patch during every patch cycle

Database Edition-Based Redefinition

11gR2 Edition-Based Redefinition (EBR)
• Key enabling technology for Online Patching
– Enables the online upgrade of the application definition
– Allows an application to efficiently store multiple copies of its code and schema in the
same database
• Provides an isolation mechanism that allows pre-upgrade and post-upgrade
schemas to co-exist
– Changes to database objects are made in the isolation of an “Edition”
– Changes to database objects do not affect the running application

Online Patching is Enabled by 11gR2 Edition-Based
Redefinition
Multiple Copies of Database Code Objects Can Coexist
• Client code connects to an “edition”
of the database
– Run Edition
• Used by online users
• Never changed by a patch
– Patch Edition
• Used by patching tools
• Changes do not affect the running application
• Patch Edition becomes the
Run Edition at Cutover

12.2 Online Patching Cycle

Online Patching Cycle Orchestration
• Formalized Patching Cycle
– New utility to orchestrate the Online Patching cycle
• adop replaces adpatch as the 12.2 patching tool
• Supports single and multi-node environments
– Dual file systems are synchronized automatically
– Database Editions are managed automatically
• Users remain online during patching
– Patching CANNOT affect the running application
• Data model changes (tables, indexes…)
• Code changes ( pl/sql, views, c code, java code…)
– Running application CANNOT affect the patch

Understanding the Online Patching Cycle
Oracle Confidential – Internal/Restricted/Highly Restricted 29
• Online Patching is used to apply all patches in 12.2
• Online Patching cycle includes 5 major phases

Prepare
• Synchronizes Patch Edition and Run Edition on the file system
• Create a new Patch Edition in the database

Preparing the File System
• Patch Edition & Run Edition of the file
systems are synchronized
• All files on the Patch Edition are an exact
copy of the files on the Run Edition
• Efficient synchronization
• Incremental synchronization is the default
• Only files changed in the last patch application
are copied
• Full synchronization available if necessary

Preparing the Database
• Patch Edition is created in the database
• All code objects in the Patch Edition begin as
pointers to code objects in the Run Edition
• Efficient use of space
• Objects are only “Actualized” into the Patch
Edition when a new revision of the code is
applied
• Storage objects such as tables are not copied
• New patching standards are followed for
upgrading storage objects

34
• ADOP controls Preparing the system for
patching
• Validates system configuration to ensure
that the system is ready to start an Online
Patching cycle.
• Prepare is run on all nodes in a muti-node
configuration
• Synchronizes the Run and Patch File System
• Creates the Database Patch Edition

Cutover

• During cutover a brief downtime is taken
–Middle tier services are stopped and users are logged off the system
–The Patch file system is promoted to be the Run file system
–The Patch database edition is promoted to be the Run database edition
–Perform final maintenance operations
–Middle tier services are restarted
–Users are brought back online on the patched system
• The database does NOT need to be and should not be bounced
during cutover

Cutover Automatically Manages all Services on all Nodes
• Middle-tier processes stopped
– Manages all nodes in the configuration
via remote execution
– End Users are disconnected
• File system roles swapped
– Patched (FS-2) promoted to Run
– FS-1 available for next patching cycle
• Database Patch Edition promoted to
Run Edition
• Middle-tier processes restarted
– Manages all nodes in the configuration
via remote execution
– Users reconnect

43
• Cutover represents the official downtime for an EBS patch
– Application tier services are automatically shut down and
restarted on all nodes
• You must ensure that no users remain on the system
during cutover
– Any third-party processes connected to the old run edition of
the database should be shut down, otherwise they will be
terminated automatically
• Cutover will take longer if it has to wait for long-running
concurrent processes to complete
– You can terminate the internal concurrent manager by
executing the adcmctl.sh abort command
What to Know
• Execute adop cutover on the primary node
$ adop phase=cutover
What to do

44
Deferring Application Tier Restart
• In some cases, you may need to perform
additional manual steps after cutover but
before restarting the application tier
services
– Apply customizations
– Patch the database tier
• You must start the application tier services
manually after performing additional steps
What to Know
without starting the application services
$ adop phase=cutover mtrestart=no

Cleanup
• Cleanup old editions to recover space
• Cleanup occurs after the users have been brought back online

• Cleanup occurs after users have been brought back
online to the newly patched Application
• File system
– The pre-patch file system is now ready for the next
patching cycle
– Re-synchronized
• Database
– Code objects patched in the latest patching cycle are
deleted from Old Editions
– Once all objects are deleted from an Old Edition it is also
deleted

47
• Users are online during the cleanup process
• Removes obsolete objects from the system to
recover space
• If you fail to run the cleanup phase explicitly, it will
be run automatically on the next prepare cycle
– This will cause a delay in starting your next online patching
cycle
• Three cleanup_modes are available
– quick - Performs only essential cleanup tasks
– standard (default) - Removes obsolete code objects
– full - Performs maximum cleanup, which drops all obsolete
code and data from earlier editions

Online Patching Cycle – Multi-Node
• Completely automated in multi-node deployments through adop
• No distinction between environments that are:
– Shared file system configuration
– Non shared file system configuration
• Primary node takes control of the patching cycle
– Performed by remote command invocations across nodes
– Remote command invocation setup required

File System Synchronization Used in this Patching Cycle: Full

Online Patching Cycle – Special Operations
54

Online Patching Cycle - fs_clone
55
Re-Cloning the Patch Edition File System
• Patch file system is normally incrementally synchronized with
the run edition file system during prepare
• In some special cases a full re-clone is required when
– The previous Online Patching cycle was aborted
– Manual changes were made to the run edition file system
– Middle-tier technology components were patched
• A full re-clone is recommended
– After applying a large EBS RUP
• Re-cloning the patch edition file system
– Ensures that the files systems are correctly synchronized
– Minimizes any synchronization delay that would normally occur on the
next prepare
• Cannot be executed when there is an active Online Patching
cycle
What to Know
• Execute re-clone on the primary node
$ adop phase=fs_clone
What to Do

Online Patching Cycle - Abort
• The Online Patching Cycle can be aborted at any time prior to
Cutover

Online Patching Cycle - Abort
57
• Useful when an Online Patching cycle encounters
problems that cannot be fixed immediately
• Returns the system to normal runtime operation
• Online Patching cycle cannot be aborted after
cutover
• Requires a full cleanup and fs_clone before the
next patching cycle to remove the effects of the
failed cycle
• If a full cleanup & fs_clone are not run explicitly,
they will be run automatically by the next prepare
– This will cause a delay during the prepare phase of the next
online patching cycle
What to Know
• Execute adop abort on the primary node
$ adop phase=abort
What to Do

Online Patching Cycle – actualize_all
58
Full Cleanup as a Periodic Maintenance Operation
• As each Online Patching cycle is completed, the
database will accumulate an additional old
database edition.
• When the number of database editions reaches 25
or more, you should consider running a special
maintenance operation to remove old database
editions
• Actualize all is a special adop phase that ensures
every database object has a version in the PATCH
edition
– This allows all copies in OLD editions to be removed by
full cleanup
What to Know
• Execute adop on the primary node to actualize all
objects and perform a full cleanup
$ adop phase=actualize_all
What to do

Online Patching Cycle - Actualize All
59
Full Cleanup Combined with a Scheduled Online Patching Cycle
• The actualize all and full cleanup can also be
executed in conjunction with an Online Patching
cycle
• This maintenance operations will take much longer
than a typical Online Patching cycle and should only
be performed when there is no immediate need to
start or complete a patching cycle
What to Know
• Execute adop on the primary node to actualize all
objects and perform a full cleanup
$ adop phase=apply patches=12345,67890
$ adop phase=actualize_all
What to do

Single File System and Downtime Patching Mode
• Designed for building & testing custom code
– Patches should always be tested on a standard dual file system test instance
before being applied to production.
• Single file system
– Allows for a reduced footprint
– Patch file system is not present
– All patches must be applied to the RUN edition using adop apply in downtime mode
• Downtime mode for adop
– Applies patches directly to the RUN edition of the instance
– The downtime mode should only be used on a production when directed by the patch readme or other
documentation

Online Patching - Testing
• Patch Edition is not a testing environment
– Application tiers cannot be run against the PATCH edition
• Patches must be tested on a test instance with a complete Online Patching cycle
– Do not used downtime mode
