Many of you would have noticed that while launching forms from Oracle Applications 11.5.10 using Internet Explorer (IE 7) then it might crash with following error. Though it may work perfectly fine in mozilla firefox.

This is the working fix for the issue.

Solution-1:

1) Take backup of jvm.dll located at c:\Program Files\Oracle\JInitiator 1.3.1.21\bin\hotspot directory.
2) Copy jvm.dll from C:\Program Files\Java\jre1.6.0_07\bin\client (or whichever highest version of jre you have) to c:\Program Files\Oracle\JInitiator 1.3.1.21\bin\hotspot
3) Clear browser cache and also Oracle Jar cache (Remove all files from c:\documents and settings\<username>\Oralce Jar cache)
4) Close all the browsers and restart

Enjoy !! The issue should have been resolved now !

Solution-2:

In case if you are unable to find the jvm.dll in that location or if the above solution didn’t work for you, you can download the working jvm.dll from this link.

Unix vi commands quick reference

General Notes:
1. Before practicing using this vi tutorial, type the following command followed by a   carriage return: :set showmode
2. vi is not VI. It is case sensitive!!! So make sure Caps Lock is OFF.

Requirements:

In order to work correctly the vi need correct terminal type (TERM) setting. The TERM setting depends on the type of terminal you have. Commonly used TERM types are vt100, vt220 and ANSI.  In most cases vt100 will work fine. In case vi is not able to understand the TERM you have given, it starts in open mode giving you a line by line display. Generally TERM is taken from .profile or /etc/profile, but can be set at the command line as:

$TERM=vt100

$export TERM

echo $TERM will display the current TERM set.
