How to create an Oracle VirtualBox host-only network adapter in Windows 7

Yesterday I have downloaded Sample Application OVM for OBIEE and while I was configuring SampleApp_V107 with Oracle VirtualBox, I have noticed VirtualBox host-only network adapter was not created. And I got below error message, when I add an VirtualBox host-only network adapter thru VirualBox console(GUI)

"Failed to create host-only network interface"

To solve this problem, I have to create an Oracle VirtualBox host-only network adapter with following steps

1. From Control Panel, Add New Hardware  (New network adapter)

2. Click Have Disk; (point it to C:\Program Files\Oracle\VirtualBox\drivers\network\netadp\VBoxNetAdp.inf)

3. Select VirtualBox Host-only Ethernet Adapter

4. OKay to install the unsigned driver

After completed instation, go to Oracle VM VirtualBox console and choose Preference network and add an VirturalBox host-only network adapter.

Again I have started SampleApp_V107 through OVM, its coming up without having any problem and working fine my OBIEE 11.1..5 sample applications

Error While Loading Shared Libraries: on RedHat Linux 5

After clonning (or installing) an Oracle Applications Release 12.0 or 12.1 instance on Linux 5, an error may occur while starting up the Apache service. The error would be this: 

You are running version 120.6.12000000.4
Starting OPMN managed Oracle HTTP Server (OHS) instance ... exiting with status 204

After review the HTTP log file. The error is very clear about the missing soft link. It would show this error:

/u01/apps/AJI_apps12/ora/10.1.3/Apache/Apache/bin/apachectl startssl: execing httpd
/u01/apps/tech_st/10.1.3/Apache/Apache/bin/httpd: error while loading shared
libraries: cannot open shared object file: No such file or directory

Soft link is missing.

To solve this issue, Shut down all Oracle Application Services

As root user, create a soft link as follows:
# ln -s /usr/lib/ /usr/lib/

Start up all Oracle Application Services
