DBA Self-Image

DBA Reality

The  More  Things  Change  

Reasons  We  Upgrade  •  Loss  of  vendor  support  •  Loss  of  compa&bility  •  Leverage  new  feature  •  Regulatory  and  Governance  requirements  •  Employee  reten&on  

Tradi&onal  Upgrade  Considera&ons  •  What  is  it  going  to  cost?  •  How  fast  can  we  do  it?  •  How  much  down  &me  will  be  required?  •  Are  there  compa&bility  issues?  •  What  is  our  fallback  if  the  upgrade  fails?  

What  We  Miss  When  a  new  feature  is  included,  at  no  cost,  Oracle  sales  does  not  know  it  exists:  Rarely  are  they  discovered  and  implemented  

Edition Based Redefinition

Predefined Inquiry Directives

Online Data Comparison

DBMS_COMPARISON

Table Compression

Save Exceptions Pragmas Bigfile Tablespaces

Virtual Columns Hidden Columns

Function-Based Indexes

Pipelined Table Functions

Block Change Tracking

Setting Optimizer Statistics

Copying Optimizer Statistics

Native Compilation

User Profiles

Password Verify Function Consumer Groups

Advanced Rewrite

Online Object Redefinition

Feature Usage Reports

Automated Partition Maintenance

Resumable Transactions

Sparse Collections Distributed Trust Administration If you buy food today and throw it away next week ... you wasted your money If you licensed valuable technology but didn't use it ...

Conditional Compilation If I taught a class tomorrow titled "Oracle New Features" and included nothing in the class that wasn't at least 10 years old almost no one in my seminar would know the difference.

What  Never  Materializes  •  Lower  Total  Cost  of  Ownership  •  Greater  Stability  •  Improved  Security  •  Improved  Performance  •  Improved  Systems  Compa&bility  

Why  They  Never  Materializes  •  We  focus  is  on  implementa&on  not  planning  •  Our  goal  is  a  higher  version  number  not  on  what,  specifically,  will  be  gained  by  the  organiza&on  

•  LiLle  aLen&on  on  knowledge  transfer  

Focus

What  12c  Mul&tenant  Can  Offer  •  Lower  Total  Cost  of  Ownership  

– You  pay  for  Oracle  licenses  by  cpu  core  – 50%  u&liza&on  =  50%  of  your  investment  wasted  – Today,  by  default,  essen&ally  all  of  Oracle's  customers  are  was&ng  ~10%  of  their  investment  in  storage  array

The database is stopped because they are "out of space." Yet 20% of the space allocated has never been used.

Industrial  Strength  Money  Wastage  Summing  the  iden&fied  space  wastage          More  than  50%  of  the  money  spent  on  disk  was  wasted  more  than  25%  totally  unusable  

Vacuum   Wasted  

Not  allocated  for  data  files   5.5T  

Freespace  in  LOB  Tablespace   6.2T  

Space  in  used  blocks   2.3T  

Total   14T  (more  than  50%  of  the  27.3T  allocated)  

What  12c  Mul&tenant  Can  Offer  •  Greater  Stability  

– The  DBMS_RESOURCE_MANAGER  package  has  been  in  the  Oracle  database  since  version  8.1.5  

– Greatly  enhanced  func&onality  in  Database  12c  – Resources  can  be  priori&zed  by  

•  Database  •  Applica&on  •  User  

What  12c  Mul&tenant  Can  Offer  •  Improved  Security  

– Unified  Audit  Policies  – New  Security  Creden&als  – Common  Users  and  Common  Roles  – Secure  Provisioning  from  Seed  Databases  – New  Data  Masking  Technology  

What  12c  Mul&tenant  Can  Offer  •  Improved  Performance  

– Superior  op&mizer  algorithms  – Superior  SQL  rewrite  capabili&es  –  Improved  resource  management  

What  12c  Mul&tenant  Can  Offer  •  Improved  CompaCbility  

– SQL  Transla&on  Profiles  

Planning  To  achieve  benefits  you  must:  

1.  Transfer  knowledge  to  your  team  

2.  Iden&fy  what  has  value  

3.  Deploy  with  a  focus  on  quan&fiable  business  benefits  

Some things cannot be done in a 2 week sprint

Summary  •  During  the  next  24  months  most  of  you  will  upgrade  to  Database  12cR1  

•  If  you  do  not  leverage  the  advantages  in  the  new  architecture  you  may  get  liLle  more  for  your  effort  other  than  a  new  version  number  

Any  Ques&ons?  

Thank  you!
