Oracle 12c introduces a new multitenant architecture that allows multiple databases to share common resources in a container database (CDB). This lowers costs by reducing instance overhead, storage costs, and DBA resource costs. It also improves manageability through fast provisioning, easier patching and upgrades, and separation of duties. Key features include pluggable databases (PDBs) that can be moved easily, cloning of databases locally and remotely, and improved patching and upgrading that is simpler and faster. Flex ASM adds high availability by avoiding single points of failure and supports larger LUN sizes and more disk groups. ASM disk scrubbing provides automatic error correction using mirrored data. Rebalance operations now provide estimates beforehand and improved accuracy of estimates
“A new multitenant architecture that easily deploy and manage database clouds. Innovations such as Oracle Multitenant for consolidating multiple databases, Automatic Data Optimization for compressing and tiering data at a higher density also maximize resource efficiency and flexibility. These unique advancements, combined with major enhancements in availability, security, and big data support, ideal platform for private and public cloud deployments.”

Oracle RAC 12c (12.1.0.2) Operational Best Practices - A result of true colla...Markus Michalewicz
This is the latest version of the Oracle RAC 12c (12.1.0.2) Operational Best Practices presentation as shown during IOUG / Collaborate15. As best practices are a result of true collaboration this will probably be the last version before OOW 2015.
Oracle 12c offers many new features and upgrading database can bring many advantages to organization. There are various upgrade and migration methods available and the best method to use for your upgrade/migration scenario depends on the source database version, the source and destination operating systems, your downtime requirements, and the personal preference of the DBA. Based upon factors there is a method available to best fit your organization needs.

Geek Sync I Need for Speed: In-Memory Databases in Oracle and SQL ServerIDERA Software
You can watch the replay for this Geek Sync webcast in the IDERA Resource Center: http://ow.ly/S6MG50A5ok5
Microsoft introduced IN-MEMORY OLTP, widely referred to as “Hekaton” in SQL Server 2014. Hekaton allows for the creation of fully transactionally consistent memory-resident tables designed for high concurrency and no blocking. With SQL 2016, many of the original restrictions and limitations of this feature have been reduced. IDERA’s Vicky Harp will give an overview of this feature, including how to compile T-SQL code into machine code for an even greater performance boost.
There’s also been a lot of buzz about Oracle 12c’s new IN-MEMORY COLUMN STORE. Oracle ACE Bert Scalzo will cover this new feature, how it works, it’s benefits, scripts to measure/monitor it and more. He will also touch on performance observations from benchmarking this new feature against more traditional SGA memory allocations plus Oracle 11g R2’s Database Smart Flash Cache. All findings, scripts and conclusions from this exercise will be shared. In addition, two very popular database benchmarking tools will be highlighted.

TECHNICAL BRIEF▶ Backup Exec 15 Blueprint for Large InstallationsSymantec
This Backup Exec Blueprint presentation includes example diagrams that contain objects that represent applications and platforms from other companies such as Microsoft and VMware. These diagrams may or may not match or resemble actual implementations found in end user environments. Any likeness or similarity to actual end user environments is completely by coincidence.
The goal of the diagrams included in this blueprint presentation is not to recommend specific ways in which to implement applications and platforms from other companies such as Microsoft and VMware but rather to illustrate Backup Exec best practices only.
For guidelines and best practices on installing and configuring applications and platforms from other companies, please refer to best practice documentation and other resources provided by those companies.
Oracle RAC is an option to the Oracle Database Enterprise Edition. At least, this is what it is known for. This presentation shows the many ways in which the stack, which is known as Oracle RAC can be used in the most efficient way for various use cases.
1. Oracle 12c New Features
Real Application Cluster (RAC)
@saifulmuhajir
2. Why 12c?
Many Oracle customers have large numbers of “departmental” applications
built on Oracle RDBMS. They:
• Do NOT use a significant percentage of the hardware on which they are
deployed
• Have instance and storage overhead preventing large numbers of
“departmental” databases from being placed on the same physical and
storage server
• Are NOT sufficiently complex to require 100% of the attention of a full
time administrator
• Do require significant time to patch or upgrade all applications
3. Oracle 11g Characters
Multiple monolithic or non-CDBs share nothing:
- Too many background processes
- High shared/process memory
- Many copies of Oracle metadata
4. New Multitenant Architecture: Benefits
Operates multiple databases in a centrally managed platform to lower costs:
- Less instance overhead
- Less storage cost
Reduces DBA resources costs and maintains security
- No application changes
- Fast and easy provisioning
- Time saving for patching and upgrade
- Separation of duties between:
• Different application administrators
• Application administrators and DBA
• Users within application
5. Multitenant Container Database

Shares:
• Background processes
• Shared/process memory
• Oracle metadata
7. Cloning, Upgrade & Patching
• Cloning:
- Local CDB
- Remote CDB (same or different server)
- Remote clone for converting non-CDB
• Upgrade & Patching: not as simple and quick as Oracle said. Require both
pre-upgrade and post-upgrade steps
10. Flex ASM
• Avoid ASM instance single-point-failure
• Number of ASM instances running is called the ASM cardinality
11. Flex ASM: More
• Supports larger LUN sizes for Oracle Database 12c clients (20 PB -> 32 PB)
• Maximum number of Disk Groups supported is 511 (from 63)
• Flexibility to rename an ASM Disk in a Disk Group
• All the instances in an ASM cluster ensure they are running the same code
release by validating the patch level across the cluster.
12. ASM Disk Scrubbing
• Monitors all the disks in the ASM disk groups
• Verifies the logical data corruption on all ASM disks
• Auto-magic error correction using mirrored data
• ASM 12c scrubbing occurs in two ways:
- As part of rebalance operations
SQL> alter diskgroup DGDATA set attribute ‘content.check’ = ‘TRUE’
- On demand scrubbing: can be performed on a Disk Group, individual
files or individual disks
SQL> alter diskgroup DGDATA scrub repair;
SQL> alter diskgroup DGDATA scrub disk data_0004 repair power auto;
13. Rebalance Improvements
• Establish upfront estimates before actually doing a rebalance operation
SQL> EXPLAIN WORK SET STATEMENT_ID='ADD_DISK' FOR ALTER
DISKGROUP DG_DATA AD DISK data_005;
SQL> SELECT est_work FROM V$ASM_ESTIMATE
WHERE STATEMENT_ID = 'ADD_DISK’;
• Improved accuracy of rebalance estimates
14. RAC: More
• IPv6 support for client connectivity, helps the customers meet the PCI,
SOX and other Security Compliance standards
• Auto root.sh execution on all nodes
• Multiple SCAN per Subnet
• New GHCTL utility for patching improvements
• Shared password file in ASM: A single password file can now be stored
in the ASM diskgroup and can be shared by all nodes
• What-if Command: simulate the command without it actually being
executed or making any changes
$ ./srvctl stop database –d MYDB –eval
$ ./crsctl eval modify resource <resource_name> -attr “value”
