Oracle Enterprise Manager Java Console and Vista 64 bit

I recently ran into an issue (again) where I was running the Java version of Oracle Enterprise Manager (OEM) 10g to manager my Oracle Databases under Vista Business 64-bit. Oracle OEM wasn't retaining my database tree settings. I would delete an old database and add a new one only to find out after I restarted the app that my changes were not retained/saved.

With the help of the MS Sysinternals utility called Process Monitor I was able to track down where these database preferences gets saved to. Turns out that they are in $ORACLE_HOME\sysman\config\pref\dbastudio-%USERNAME%.crd. After tweaking the security permissions (taking ownership and allowing my account 'full access') OEM returned to normal saving operation.

Using Posix 7zip on the Cosole for Fast Compression

7zip has a fast compression algorithm using LZMA2 with as many threads (logic processors, cores, etc) as you like.  In this article we are focusing on the Posix version of 7zip for linux/unix. Here is an example command: 7za a -m0=lzma2 -mmt=2 -mx=1 MyZip.7z mydatabase.dpdmp -m0=lzma2 tells 7zip to use the LZMA2 compression algorithm. -mmt specifies the number of logic processors to use (multi threads) -mx=1 tells 7zip to use the fastest compression This is faster and better compression than zip and gzip and while comparable to bzip2 in size it is way faster than bzip2. Throw that together with a command that detects the number of logical processors and you get a function that discovers how many CPU's to use. LCPU=`cat /proc/cpuinfo | grep processor | wc -l` 7za a -m0=lzma2 -mmt=${LCPU} -mx=1 MyZip.7z mydatabase.dpdmp

Windows 7 x64 and Oracle 10g R2 Client Installation

By default Windows 7 x64 is not support in Oracle 10g R2, but 10gR2 does support Windows 2008 x64, so it should work with Windows 7 after some tweaking. Tweak the following two files: .\stage\prereq\db\refhost.xml .\stage\prereq\db_prereqs\db\refhost.xml To add the BOLD text below: <certified_systems> <!--Microsoft Windows 7--> <operating_system> <version value="6.1"> </operating_system> </certified_systems> Next edit the ./install/oraparam.ini file making the BOLD changes/addition: [Certified Versions] #You can customise error message shown for failure, provide value for CERTIFIED_VERSION_FAILURE_MESSAGE Windows=5.0,5.1,5.2,6.0, 6.1 Then just run the installer as Administrator and you are done.
