- Deployment specifications

- Component Knowledge Modules

• Debugger

• WebLogic Management Framework

• Improved performance

- Parallel target table load

- Session blueprints

• Enhanced KM and Procedure editors
13

GoldenGate and ODI - A Perfect Match
• JKM Oracle to Oracle Consistent (OGG) Knowledge Module

- Oracle Data Integrator Metadata used to generate GoldenGate parameter files  
(extract, pump, replicate) and 
configuration files

- Delivered with ODI

• ODI CDC Framework generated

- Staging table - replicate of  
source

- J$ (journal) table - change rows

• Journalized data used in  
transformations (via JV$ views)
14

Oracle Data Integrator - Journalizing (CDC)
• Oracle Data Integrator Change Data Capture (CDC) delivered via Journalizing

- Identify, capture, and deliver changes made to source data

- Journalizing Knowledge Module (JKM) performs setup and  
creates infrastructure

• ODI CDC Framework

- Capture Process - mechanism for capturing changed data from the  
source database (Ex. Oracle GoldenGate)

- Journals - tables (J$) hold references to changed records and the  
change type (insert / update / delete)

- Journalizing Views - (JV$, JV$D) provides access to changed data,  
used by IKM / LKM in mappings

- Subscribers - used to allow consumption of changed data at different intervals, for multiple
applications, etc.
15

Upgrade to 12c - The Goal
• Minimize interruption to source and target systems

• Minimize downtime
16

GoldenGate Upgrade Considerations
• GoldenGate 12c is supported by the 64-bit OS only
(Oracle installations)

• Start with simple upgrade, then implement new
features (integrated replicat, integrated extract, etc)

• Parameter file updates

- Quoted object names - use the convprm tool

- Upgrade extract (or replicat) only

- Character-Set conversion can be handled
17

Upgrading GoldenGate 11g to 12c - convprm
• Run prior to performing the upgrade on a backup of the files

18
Usage: convprm [options] <list of file names>

-h, --help: displays usage.

-v, --version: displays version information.

-i, --follow-include: also converts files included through an OBEY or INCLUDE directive.

-n, --no-backup: does not create a copy of the original file.

-s, --silent: does not display status messages.

-q, --quotes: performs quote conversion (active by default).

-b, --before-function: converts from BEFORE.column syntax to @BEFORE(column) (active by default).

-d, --dry-run: does not change the input or create a backup file. It only prints out what would happen.

•Start with the dry run

Upgrade GoldenGate 11g to 12c Steps
• Ensure all transactions have completed on source database and extract

- Source system outage is necessary only when SQL or DDL operations are
performed

• Record current SCN

• Stop all process groups and managers on source & target

• Install GoldenGate 12c

• Upgrade the supplemental logging on the source (ulg.sql)

• Set the extract, pump, and replicat to start at the recorded SCN

• Start the processes!
21

Upgrade GoldenGate 11g to 12c - Source Preparation
• Check for long-running transactions

INFO EXTRACT group, SHOWCH
• If needed, restore archive logs to checkpoint…

• Or…”clear” them using FORCETRANS or SKIPTRANS or wait for completion

22

• Record the current SCN

SQL> select current_scn from v$database;
• Check the extract to determine if it has
completed processing transactions

23

• If not upgrading the replicat, add:

- exttrail /u01/sogg/dirdat/EXToc/oc, format release 11.2

• Stop the extract group(s)
24

Upgrade GoldenGate 11g to 12c - Target Preparation
• Ensure the replicat has completed processing all transactions, then stop the process

• Stop the source and target manager processes
25

Upgrade GoldenGate 11g to 12c - Installation
Install GoldenGate 12.1.2 into the current source and target directories
26

• If the source or target is Oracle 11.2.0.4 or 12.1.0.2+, set the ENABLE_GOLDENGATE_REPLICATION
initialization parameter to TRUE

• Run the ulg.sql (update log group) script on the source system to update the supplemental logging

- Supplemental log groups must have been created via Add Trandata

27

• If the source or target is Oracle 11.2.0.4 or 12.1.0.2+, set the ENABLE_GOLDENGATE_REPLICATION
initialization parameter to TRUE
• Run the
- Supplemental log groups must have been created via Add Trandata

Upgrade GoldenGate 11g to 12c - Update Logging
27

Upgrade GoldenGate 11g to 12c - Finalize Upgrade
• Alter the extract (and pump) processes to write a new sequence number

• Issue the command info extract groupname, detail to get the new sequence number
28
GGSCI (ODIGettingStarted) 3> alter extract EXTC ETROLLOVER
2014-12-03 19:13:52 INFO OGG-01520 Rollover performed. For each affected output trail
of Version 10 or higher format, after starting the source extract, issue ALTER EXTSEQNO for
that trail's reader (either pump EXTRACT or REPLICAT) to move the reader's scan to the new
trail file; it will not happen automatically.
EXTRACT altered.
GGSCI (ODIGettingStarted) 4> alter extract REPSP ETROLLOVER
2014-12-03 19:14:07 INFO OGG-01520 Rollover performed. For each affected output trail
of Version 10 or higher format, after starting the source extract, issue ALTER EXTSEQNO for
that trail's reader (either pump EXTRACT or REPLICAT) to move the reader's scan to the new
trail file; it will not happen automatically.
EXTRACT altered.

Upgrade GoldenGate 11g to 12c - Finalize Upgrade
• Alter the extract (pump) and replicat processes to begin at the new sequence number

• Start the processes on source and target

29
GGSCI (ODIGettingStarted) 7> alter extract REPSP, extseqno 14, extrba 0
EXTRACT altered.
GGSCI (ODIGettingStarted) 1> alter replicat REPSA1, extseqno 14, extrba 0
REPLICAT altered.

Oracle Data Integrator Upgrade Considerations
• Can be completed before or after GoldenGate upgrade

• Interfaces will be converted to Mappings using the  
DataSet component

- Further work necessary to fully utilize flow-based  
Mappings

• Agent upgrade

- If possible, install new agent. (WLS must be upgraded to 12c anyway).

- If not…follow upgrade procedure.

• Upgrade key - used to migrate additional objects later
30

Upgrade Oracle Data Integrator 11g to 12c Steps
• Backup environment and clone repositories

• Install ODI 12c

• Run RCU to add new supporting 12c schemas

• Run the Upgrade Assistant
31

Upgrade ODI 11g to 12c - Preparation
• Backup the existing environment and clone
the repositories for upgrade

- Ensure the table schema_version_registry has an
ODI entry (Support Doc ID 1622194.1)

- Set the work repository schema JDBC URL to the
cloned version

32

Upgrade ODI 11g to 12c - Installation
• Install ODI 12c

- Use JDK 1.7.xx

- Choose a new Oracle Home

33

Upgrade ODI 11g to 12c - Run RCU
• Run the RCU to create additional schemas necessary

- AS Common Schemas (Common Infrastructure Services)

34

Upgrade ODI 11g to 12c - Upgrade Assistant
• Stop all services (agents, close ODI Studio)

- [oracle@ODIGettingStarted bin]$ ./agentstop.sh -NAME=ODIAGENT 
2014-12-04 19:25:56.075 NOTIFICATION OracleDI: Stopping Agent ODIAGENT…
• Run the Upgrade Assistant

- [oracle@ODIGettingStarted bin]$ pwd 
/home/oracle/odi12c/oracle_common/upgrade/bin 
[oracle@ODIGettingStarted bin]$ ./ua

37

Review the Upgraded Mappings
38

Reusable Mappings - Cleanup Required
• Temporary Interfaces are now Reusable Mappings

• 3 Mappings are generated: 1 Mapping & 2 Reusable
Mappings

• Cleanup required to remove the unused mappings

ODI and GoldenGate Integration
• Journalizing is still enabled
and running

- Still using the 11g JKM

45

Move to ODI 12c Journalizing Knowledge Module
• Import the JKM

• Configure and start
JAgent on source/target

• Setup the GoldenGate
Data Server/Physical
Schemas (Online)

• Change the JKM in the
Model and set the
Options
46

Summary
• Upgrade both GoldenGate and ODI at the same time or individually

- Backup and clone environment

- Use tricks, such as “Convert to Flow”, to finalize migration to 12c

- Journalizing integration will still work after upgrade of ODI

• Minimize interruption of source and target

- Capture source SCN before upgrade and restart GoldenGate at
that point in the transaction logs

• Oracle documentation is good!
