4. About GIA and TCS About GIA and TCS
Established in 1931, GIA is the world’s foremost authority on diamonds, colored stones, and pearls. A public benefit, nonprofit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry Industry.
TATA Consultancy Services Limited (TCSL) is a multinational information technology (IT) service, consulting and business solutions company headquartered in India. It is a subsidiary of TATA group. TCS is a leader in the global marketplace and among the top 10 IT services provider in the world.

5. Understanding Global GIA’s IT needs
GIA is a global Institution having nine Grading Laboratories around the globe. Its major computing needs are supported by two major production data centers and two DR data centers.
GIA’s Grading Data is very global as it is created , distributed and shared among all its labs to support various grading services for the global customer base. A combination of high OLTP plus resource heavy back end processing supported by a detailed workflow engine.
GIA’s global customers demand fast stone turnaround time as trade operates with very low profit margin among its supply chain. High turnaround time is understandably unacceptable.
One of GIA’s missions is to empower trade and general public alike with as much grading data as possible in a timely fashion for making informed decisions.
Finally, Diamonds are forever and hence data archival is out of question. We need to keep all our data from day one.

6. NGGS Initiative Goals for NGGS
Scalable and efficient Next Generation Grading System (NGGS) to help GIA service its growing customer base with quicker turnaround time and to address ongoing application performance issues.
Highly Scalable platform with less or no interruption of service to support rapidly growing global expansion.
Performance. Performance for high throughput for both internal and external users.
Platform Consolidation and Standardization.
Address Itanium end of life support issue from Oracle.
Highly available architecture like ExaData to address Business Continuity / Downtime / Stability issues .

7. Selection of ExaData and ExaLogic and Timeline
We compared and deliberated on different hardware platforms like IBM, HP and Oracle. No comparable hardware were available to match the configurations and features of ExaData and ExaLogic.
We ran and tested our database copy in Oracle’s Engineered Systems lab in Santa Clara for performance of our most used queries and processes.
Very impressive performance numbers just out of the box with no tuning of any sort.
Implementation Timeline.
Engineered System was Implemented in Carlsbad during July, 2013 timefreame
Engineered System was implemented in Mumbai during Nov, 2013 timeframe.
DR Databases in NY and Hong Kong was implemented using ODA in early 2014.
Upgraded to Quarter Rack from 1/8 ExaData in July, 2014.
Upgraded to Quarter Rack from 1/8 ExaLogic in August 2014
Both the upgrades (scalability feature) went without any hiccup.

10. Business Benefits

11. A Paradigm shift in Data Integration and availability today at GIA
ExaData helped us enable and integrate our live grading service data with many customers using web services APIs 24x7 .
Large customers today run their customer portals accessing data from our database live.
We integrate 80-90% of our data with all our customers as part of our mission to help trade and public with all the data that they need to be well informed.
Due to our old hardware constraints we were quite restricted on how much of API service data we can enable in fear of production performance 24x7.
From 2-4 customers in the past, today we serve close to 300 customers using web services without impacting production performance.
Business expanded their operation hours from one shift to three shifts which is in all practical purposes a 24x7 operation around the globe.
Struggled with balancing performance and data availability during backup and other database maintenance window.
In Exadata, now business runs 24x7 with no impact on its performance while we carry out all database maintenance activities like backups, stat collection and merge activities behind the scenes.
Additional reporting and compliance databases for business operations.

12. Top Five -1- Business Benefits
Performance improved 30x without any change to Query or Process.
We can run records query against any size stone without restriction.
Performance in Records Query.
An integrated and critical process step in the grading workflow.
Each stone data is compared against archived data (~ 160 Million) for stone identification and fraud detection at multiple steps. Poor Query/database performance resulting in long grading delays.

13. Top Five -2- Business Benefits
Service Interruptions. Very Frequent Application Java run-time Error and Restart of Application JVM and Service Interruptions.
Upgrade to ExaLogic from x86 based Platform.
Not a single instance of java run-time Application error or JVM restart ever since we upgraded to ExaLogic.
No more unable allocate memory error.

14. Top Five-3- Business Benefits
Data Consolidation between databases.
A SQL Merge Process of about 200G every four hours.
Process time reduced to 30 minutes from 8 hours between databases.
This helped us service our global customers with improved current stone status, order additional services, reorder services and Workflow status etc.
Limits on how many stones we can transfer and merge between databases were removed.

15. Top Five -4- Business Benefits
Server Consolidations.
ExaData for Database Servers Consolidation and ExaLogic for Application Servers Consolidation.
Consolidated three database servers into one ExaData System (1/8 of a Rack).
Consolidated Nine Application Servers into one ExaLogic System (1/8 of a Rack)
By End of 2014 we would have consolidated all our ERP Databases into this single box. A single box will cater to all of GIA’s production database needs.

16. Top Five -5- Business Benefits
Backup and Maintenance, 24x7 Business Operation
Longer backup time and maintenance window was impacting 24x7 business operation requirement, application and database performance.
RMAN Backup time reduced from 5 hours to 30 minutes.
Export Backup time reduced from 6 hours to less than one hour.
Statistics collection gets completed in 10 minutes from 6-8 hours
Additional reporting and compliance databases for data mining and intelligence.
Business operations continues without any impact from these activities.
RMAN Backup time reduced from 5 hours to 30 minutes.
Export Backup time reduced from 6 hours to less than one hour.
Statistics collection gets completed in 10 minutes from 6-8 hours

Transportable Database
Transportable Tablespace
TCS Recommendation
TCS chooses Logical Approach - Oracle data pump. This strategy has following pros and cons:
This is simpler solution because data is not changing during migration but it incurs more downtime.
No need to upgrade the source database.
Platform migration is supported.
Oracle data pump provides the network import feature that eliminates the need to stage outside of the database. When using this feature with large partitioned tables, investigate using the QUERY parameter manually separate the data being imported across several jobs so that all available computing capacity can be leveraged.

30. Challenges & Best Practices
Typical Challenges
Best Practices
JAR Compatibility Issues (ADF, commons etc.)
JVM compatibility Issues (jrockit v/s Sun)
Heap Parameter tuning (more memory required especially due to 64 bit)
http parameter tuning (session time out, client connections)
Code specific issues due to changing library JAR (WebLogic parser is strict parser, hence java scripts needs to be revisited, required code change)
Application specific parameter (weblogic.xml, weblogi-application.xml for session parameters, file size, filters, mime type etc.)
Analyze existing AWR reports to isolate the critical tables and queries
import using sorted order based on the AWR analysis
Write back flash cache to absorb random reads
SDP listener between exadata and exalogic
NFS over infiniband for high speed connectivity for Backups as well as imports.
RAC gridlink for RAC aware connectivity
Weblogic clustering to be explored for even better session availability and resilience.
