Oracle has released it’s first patch set for Oracle Database 11g Release 2 (22.214.171.124).
See the README at Oracle® Database Patch Set Notes 11g Release 2 (126.96.36.199) Patch Set 1 and Metalink Note ID 1189783.1 at Important Changes to Oracle Database Patch Sets Starting With 188.8.131.52 for more information.

The Oracle Database version compatibility matrix and version support status matrix are almost mandatory when installing or upgrading clients or servers.
For information about patches, go here: Oracle database patches for Linux and Windows (on Metalink).
For announcements of security fixes, go to Critical Patch Updates, Security Alerts and Third Party Bulletin.
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

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
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

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:

Ever had the “wrong authentication protocol” error when using Xming and xhost+ still did not work?
When you are on a private network, you can try using the “-ac” option when starting Xming. Use this only on private trusted networks, because it gives access to everyone.
For mote information on Access Control in Xming and X-Forwarding with PuTTY and SSH, check the Xming troubleshoot guide.
