Today Oracle released a very large „monster“ Upgrade. This July 2017 Update includes the first time the new RU „Release Upgrade“ and RUR „Release Update Revision“ Patches.
To be up to date read the following My Oracle Support Doc-ID’s
Actually I can’t find a FAQ but I think this will come in a few weeks.
Stay tuned :-)
Vor zwei Jahren als Oracle ACE Associate gestartet, wurde ich nun zum Oracle ACE „befördert“. Vielen Dank
Two years ago I started as Oracle ACE Associate and now I was „promoted“ to the Oracle ACE status. Many Thanks
If you need a good overview and introduction in Oracle 12.1 RAC take a look to the following document.
During a lot of SQL Performance activities I saw all the time the following message but why?
Note ----- - 'PLAN_TABLE' is old version
Yes, I did a few days before an Upgrade from 11.2.0.4 -> 12.1.0.2. Now I start to check out some important SQL Queries but I the „old version“ message
sqlplus set autotrace traceonly explain select * from dual; and again Note ------ 'PLAN_TABLE' is old version
Problem is that this message came up while the plan_table came from the previous version in my case 11.2.0.4. So the solution for this is very easy
In the new environment here 12.1.0.2 SQL> connect sys as sysdba SQL> drop table plan_table$; SQL> @?/rdbms/admin/catplan
This shoud fix the problem and if not?
Okay it could be possible that you should drop the plan_table as Schema User and then run the the SQL again.
Here an example output: Note ----- - dynamic statistics used: dynamic sampling (level=2) - automatic DOP: Computed Degree of Parallelism is 8 because of degree limit - parallel scans affinitized for buffer cache
Happy birthday Oracle :-)
I just do some tests with the Oracle 12.2 Release and while doing tests it is all the time better to have a second database and that is the time for rman. So I looked around and found an easy way to duplicate a database from a Backup. Here the details:
My environment
OL 7.3 with an Oracle 12.2 + DATABASE BUNDLE PATCH: 12.2.0.1.170516 (25862693)
I setup an database via dbca and use Standards including the fast recovery area. Oh yes the FRA is a standard now
Next I did a backup and here I did a few tests with image copied and „backup as copy database“. While doing this I had a full backup on disk and that is the point to start with the duplicate.
What are the steps?
First I created a initdb2.dup
Yes, for testing I create only one controlfile initdb2.dup *.audit_file_dest='/u01/app/oracle/admin/db2_s1/adump' *.audit_trail='NONE' *.db_name='db2' *.db_unique_name='db2_s1' *.control_files='/u01/app/oracle/fast_recovery_area/db2_s1.ctl' *.db_create_file_dest='/u01/app/oracle/oradata' *.db_recovery_file_dest_size=8G *.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area' *.enable_pluggable_database=true *.large_pool_size=256M *.sga_target=2G
Next I created a few directories and then I started the new instance
sqlplus / as sysdba startup nomount pfile=/u01/app/oracle/admin/db2/pfile/initd2.dup'
finally I start the duplicate from „BACKUP LOCATION“
rman auxiliary / RMAN>duplicate database to db2 backup location '/u01/app/oracle/fast_recovery_area';
That’s it finished :-)
Keep in mind that I set my environment before starting the rman duplicate and the connection is done against the auxiliary instance. Yes, it is very easy to do a duplicate to a new database when you have a full backup on disc.
I found a old video concerning the „real“ production of an Oracle Engineered System but it’s really good and cool stuff.
Have fun
Yes and now Oracle 12.2 is available (Linux x86_64) for download from OTN.
Let’s start with Installation and Setup ….
Last year in October Oracle released the Oracle Database Security Assessment Tool (DBSAT) to analyzes database configurations and security policies to improve the security in your environment.
Real benefits
What does DBSAT check
Installation and Requirements
DBSAT runs on
Solaris x64 and Solaris SPARC
Linux x86-64
Windows x64
HP-UX IA (64-bit)
IBM AIX & zSeries Based Linux
Supported Database Versions
on Oracle Database 10.2.0.5 and later releases.
Download DBSAT

Transfer the files to your local PC
Here an example I converted the XLS File as PDF
Start reviewing the security report and fix the critical findings
Summary
Note
While running dbsat in a 12c Multitenant environment you must create the report on every PDB, otherwise you will get only a report from the CDB
Try it and have fun :-)
