Exadata X4-2’s Compute Power: Exadata X4 Storage:
· 50% more database cores · 2X larger physical flash memory
· 2X larger database
server local storage · . Up to 4X larger logical flash memory
· 2X faster InfiniBand network 2X larger disks
Key database optimizations include:
- More database query offload to storage can offload searches of LOBs
- Database optimized compression now includes Hybrid Columnar enhancements for transaction processing
- Database optimized PCI Flash enables ultra high speed flash compression (X4) at multi-million IOs/second, as well as caching for table scans and faster file initialization
- Database optimized QoS prioritizes CPU and IO use by multitenant pluggable database (12c)
- Database optimized availability allows for prioritized recovery of critical database files
- Database optimized messaging prioritization of critical database messages, including log writes and Oracle Real Application Clusters
Why Exadata ?
Exadata Database Machine is designed to address common issues:
>>Data Warehousing issues:
Supports large, complex queries
Managing Multi-Terabyte databases
>> OLTP issues:
Supporting large user populations and transaction volumes
Delivering quick and consistent response times
>> Consolidation issues:
Efficiently supporting mixed workloads(OLTP & OLAP)
Prioritizing workloads(IORM)
>> Configuration Issues:
Creating a balanced configuration without bottlenecks
Building and maintaining a robust system that works
>>Redundant and Fault Tolerant:
Failure of any component is tolerated.
Data is mirrored across storage servers
Basic Components of Exadata are Compute node(DB node, Cell nodes, Ibswitches,PDU's,Cisco
switches).

>>List of Command line interface utility for compute node and Cell node show below in diag
 |
| Diag 1:Command categories |
- CellCLI - the Exadata Storage Server. To manage this, Oracle provides a command line tool: CellCLI (Cell Command Line Interpreter). All the cell-related commands are entered through the CellCLI.
- DCLI - The scope of the CellCLI command is the cell where it is run, not in other cells. Sometimes you may want to execute a command across multiple cells from one command prompt, e.g. shutting down multiple nodes. There is another command line tool for that: DCLI.
- SQL – Once the cell disks are made available to the database nodes, the rest of the work is similar to what happens in a typical Oracle RAC database, in the language you use every day: SQL. SQL*Plus is an interface many DBAs use. You can also use other interfaces such as Oracle SQL Developer. If you have Grid Control, there are lots of commands you don’t even need to remember; they will be GUI based.
- ASMCMD – ASMCMD this is the command line interface for managing ASM resources like diskgroups, backups, etc.
- SRVCTL – SRVTCL is a command-line interface to manage Oracle Database 11.2 RAC Clusters. At the database level, most of the commands related to cluster, e.g. starting/stopping cluster resources, checking for status, etc. can be done through this interface.
- CRSCTL – CRSCTL Cis another tool to manage clusters. As of 11.2, the need to use this tool has dwindled to near zero. But there is at least one command in this category.
- These are the basic categories of the commands. Of these only CellCLI and DCLI are Exadata specific. The rest, especially SQL, should be very familiar to DBAs.

Oracle Traffic Director Optimizations
Enabling SDP use to the wls origin servers
You can also optimize the communication between the OTD nodes and WLS
managed servers in the Origin Server Pool. The optimization is to enable OTD to
communicate with the origin server pool managed servers using the SDP protocol.
By doing so, the communication channel between the OTD frontend and the WLS
application tier is optimized to the fullest extent to take advantage of the Exabus
performance capabilities. Configuration change is required on both the OTD and the
WLS ends.
OTD
1. Log in to the OTD administration console for your environment using the
browser.
2. Select Server Pools and then origin-server-pool-1 that you created.
3. Search for the Address Family and using the drop down list change it to inetsdp.
4.Click Save.
5. Select each of the origin servers in the origin-server-pool.
6. Change the port from 7101 to 7102
7. Click Save.

Introduction for Oracle Engineered systems
-------------------------------------------------------
Engineered systems are pre-designed, pre-engineered, pre-configured and pre-tested to cut short IT complexity, reduce costly maintenance, integration and testing tasks and power real-time decision making with extreme performance.
Traditionally, IT departments have been required to install and configure software that is hosted on hardware that was itself installed and configured separately. Oracle Engineered Systems relieve this burden from the IT department by providing a pre-defined combination of hardware and software.Oracle Engineered Systems is a complete set of integrated hardware and software that is designed to reach a predetermined level of capability, capacity, and scale. This relatively new concept of an integrated hardware and software solution, dedicated to provide a specific service, changes the way one must think about architecture in IT environments.
Some engineered systems are listed below:-
Oracle Exadata Database Machine->>To host Critical Database application
Oracle Exalogic Elastic Cloud>>Middleware
Oracle Exalytics In-Memory Machine>>
Oracle SPARC Super Cluster
Oracle Private Cloud Appliance
Oracle Database Appliance
Oracle Big Data Appliance
Zero Data Loss Recovery Appliance
