DBCA not Starting Oracle11gR2 Exception in thread "main" java.lang.NoClassDefFoundError: oracle/i18n/text/OraMapTable

Few days ago i tried to install Oracle11g Release 2 on Oracle Enterprise Linux 5 (OEL) on my Macbook Pro using VMware Fusion 3 to Virtualize Linux while installing i was getting error about missing files

Here is the error screen  http://img682.imageshack.us/i/11gerror.tif/

I was ignoring the error and thought that may be 11g is not supported on VMware Fusion and OEL setup because i was not able to install Oracle10gR2 as well from DVD on OEL5 which is working fine on RedHat Linux AS 4 on my laptop.




After installing (By ignoring missing files) i was running dbca and error was coming

Any ways Problem was in ZIP file that i downloaded the chksum was showing wrong information so i downloaded the file linux.x64_11gR2_database_1of2.zip again and everything works perfect..
at OTN the file


linux.x64_11gR2_database_1of2.zip (1,239,269,270 bytes) (cksum - 3152418844)
linux.x64_11gR2_database_2of2.zip (1,111,416,131 bytes) (cksum - 3669256139)

Solution:

--Run on Linux to make sure cksum is correct
cksum linux.x64_11gR2_database_1of2.zip
cksum linux.x64_11gR2_database_2of2.zip


i will recommend plz make sure cksum is returning same value as mentioned before installing.

Cheers,
