OTech Magazine Issue #4: Summer 2014 Published

Image
OTech Magazine - The independent magazine for Oracle professionals. Yesterday fourth issue of the OTech Magazine published.



 In this issue also included my article: Oracle Database 12c: Cross Platform Transport non-CDB to PDB using RMAN Backup Sets




You can download online OTech Magazine #4 Isssue - Summer 2014

Summary of article
We can create a PDB using upgraded database (non-CDB) and can be adopt the 12.1 non-CDB into a CDB as a PDB. This article covers steps for cross-platform data transport of non-CDB to other platform and adopt the transported non-CDB into a CDB as a PDB. If 12.1 non-CDB and CDB running on same platform, then easily plug-in the non-CDB into a CDB as a PDB so, there is no need for any conversion of platform on non-CDB. If platforms are different, then we need cross-platform data transport of non-CDB with RMAN. Prior to Oracle Database 12c (12.1) RMAN only used image copies for cross-platform data transport. After 12.1 RMAN can be use backup sets for cross-platform …

This feature further improves rapid provisioning of pluggable databases. Administrators can spend less time on provisioning and focus more on other innovative operations. Follow examples:

Oracle Database 12c Release 1 (12.1.0.2) New Features

Image
Oracle Database 12.1.0.2 is available for download now.  here

1. Advanced Index Compression

Advanced Index Compression works well on all supported indexes, including those indexes that are not good candidates for the existing prefix compression feature; including indexes with no, or few, duplicate values in the leading columns of the index.

Advanced Index Compression improves the compression ratios significantly while still providing efficient access to the index.

2. Approximate Count Distinct

The new and optimized SQL function, APPROX_COUNT_DISTINCT(), provides approximate count distinct aggregation. Processing of large volumes of data is significantly faster than the exact aggregation, especially for data sets with a large number of distinct values, with negligible deviation from the exact result.

The need to count distinct values is a common operation in today's data analysis. Optimizing the processing time and resource consumption by orders of magnitude while providing almost ex…

Oracle Multitenant - 12 Jul at Orient ITM

Image
I presented entitled "Oracle Multitenant" at an event organized byOrient ITM.  (Baku, Azerbaijan).

What is Oracle Multitenant?

A new option for Oracle Database 12c, Oracle Multitenant delivers a new architecture that allows a multitenant container database to hold many pluggable databases. An existing database can simply be adopted with no application changes required. Oracle Multitenant fully complements other options, including Oracle Real Application Clusters and Oracle Active Data Guard.

The many pluggable databases in a single multitenant container database share its memory and background processes. This enables consolidation of many more pluggable databases compared to the old architecture, offering similar benefits to schema-based consolidation but with none of the major application changes required by that approach.

Creating pluggable databases, moving pluggable databases between containers, and cloning pluggable databases are done with new SQL commands and take just…

Oracle Database 12c: What happens during CDB startup if one the PDB has a media problem? - Continue

During Oracle Day 2014  (February 05, 2014, which was held in Baku/Azerbaijan), I met with my friends and had a conversation about several topics.

I asked to my friend Teymur Hajiyev, what happens during CDB startup if one the PDB has a media problem? He said, CDB must open without a problem. But you need to open PDBs manually. In other words, by default PDBs in mount mode, you need call alter pluggable databases all open.

After Oracle Day, Teymur shared his tests in here. and faced the same issue. But he is wrote : If you apply PSU1 on 12c, you will not meet with such problem, CDB will skip opening problematic PDB and will open other PDBs.

I will share my tests on patched database. I applied PSU1 to my database server:  Installation and configuration Patch 17552800 - 12.1.0.1.2 Patch Set Update

My test environment as below:
