The Oracle Database version compatibility matrix and version support status matrix are almost mandatory when installing or upgrading clients or servers.
Oracle Database client / server version compatibility matrix
Oracle calls this Client / Server Interoperability Support, Note ID 207303.1
Oracle Database version release support status matrix
Oracle calls this the Database Releases Support Status Summary, Note ID 161818.1
You will be redirected to Oracle Support and you must be registered to gain access to the pages. I did not include the matrices, because these change over time.
Oracle Information about Windows 32 / 64 bit database and client versions
Certification Information for Oracle Database on Microsoft Windows x64 (64-bit), Doc ID 1307195.1
I knew in Oracle 11g with Automatic Memory Management (AMM), the database was able to give unused memory back to the OS, controlled by MEMORY_TARGET and MEMORY_MAX_TARGET.
This mechanism is present in 11g since day 1 (in 2007), but I never actually played with it.
MEMORY_TARGET and MEMORY_MAX_TARGET
The Oracle documents state the following:
MEMORY_TARGET specifies the Oracle system-wide usable memory.
MEMORY_MAX_TARGET (…) decide on a maximum amount of memory that you would want to allocate to the database for the foreseeable future.
So my guess is, MEMORY_MAX_TARGET (static) is the maximum you can set MEMORY_TARGET (dynamic) to. A couple of days ago, I wanted to experiment a bit with these memory settings.

I have been trying to import a private key into ConnectBot for Android.
The key I’m using is working fine when using Putty, but does not work for ConnectBot.
To make it work for ConnectBot, you need to have a OpenSSH version of this file.
Luckily one can also use PuTTYgen to create an OpenSSH key.
In Puttygen, do the following:
- Load the private key: [File] -> [Load Private Key] (*.ppk)
- Enter passphrase if applicable
- Goto: [Conversions] -> [Export OpenSSH key] and save

In this blog post I will talk about the basic workings of Automatic Undo Management, which can cause ORA-01555 and ORA-30036 issues.
The scope is Automatic Undo Management used in 10g and 11g, but has to be explicitly set for 9i (UNDO_MANAGEMENT = AUTO). Manual Undo Management is out of scope for this blog.
The Undo tablespace is a normal tablespace like any other, but only Oracle is controlling what is happening inside it.
The Undo tablespace is used for several features: ROLLBACK, READ CONSISTENCY and FLASHBACK technology. Continue reading →
I have been moving sites and urls around and found this page to be very handy to implement friendly http 301 redirects.
This HTTPS via utl_http using orapki recipe is prepared with certificates and the orapki tool having some sweet and spicy taste. You may also use the Oracle Wallet manager instead of using orapki but for Oracle RDBMS you will need to have Enterprise Edition and Advanced Security pack licenses. Continue reading →
Installing the Oracle Instant Client will save you ~600 megabyes compared to the ‘full’ Oracle Client.
- Download Basic Package from the Oracle site
- Unzip to directory x (your ORACLE_HOME)
- Set PATH (Windows) or LD_LIBRARY_PATH (*nix) to the Instant Client directory x
- Move TNSNAMES.ora to directory x/network/admin (or set TNS_ADMIN and ORACLE_HOME).
- Extend with SQL*Plus Package (optional)
- Start your application
Read my full article here: Whiteblog – Installing the Oracle Instant Client. (links in referred blog might not work!)
OLE DB, .NET and ASP.NET drivers are not included in the instant client (first Oracle link might suggest it is). These are included in the ODAC package, download them separately at these locations:

They have finally arrived, the Windows 64 and 32 bit versions of Oracle 11gR2.

The 64 bit version was released a bit earlier, so I was hoping the 32 bit version would not come… Why do we want the 32 bit versions? Older systems? Ancient systems! Why…?!
Now I don’t have an excuse to update my almost 10 years old Windows XP OS (running on 64bit hardware) to a much nicer Windows 7 64 bit. The only excuse now is that I could use 600+ megs of memory… enough to run that XP OS virtually!
