Page Expired Message Using Oracle EM Cloud Control 12c
A very common and annoying issue you will encounter when using Oracle Enterprise Manager Colud Control 12c is the Page Expired message after certain interval.
Page Expired
“The Page has expired. Click OK to continue.”
By default Session Timeout is set to 45 minutes after which your page expires if there is no activity by your session. This feature is controlled by maxInactiveTime.
To increase the Session Timeout and avoid frequent Page Expired issue you can set this value as per your requirement. Setting its value to -1 will keep your session forever without expiring.

You should have an Oracle database up and running that can be used as Management Repository, before you start the installation. My Management Repository database is running on the same host where I would be installing OEM Cloud Control 12c(OMS.You can have your repository database running on a different host as well.
Before you begin ensure following prerequisites should be on the host server.

Convert Database To ASM While Upgrading to 11g via RMAN
This article helps you to convert your database residing on filesystem to ASM during 11g upgrade on to a new server. The best part is that the conversion to ASM, migration to new server and upgrade to 11g can all be done simultaneously without having it to break up in phases.
We can recover the database to a new server from the last backup and upgrade the database after restoration via RMAN.
I have used below environment to perform this test.
Source
Hostname : OLXPTEST1
Operating System : OEL 5.3 (32 bit)
Oracle Version : 10.2.0.5
Target
Hostname : OLXTEST2
Operating System : OEL 6.1 (32 bit)

Oracle 11.2 Standalone Database Creation Using ASM Manually
In this article we will see how we can configure 11.2 standalone database with ASM manually. You might have to create ASM instance manually when you want to have allocation unit (AU_SIZE) other than 1 MB(default). For 11.2.0.1 and 11.2.0.2 Grid Installation OUI or AMSCA does not have provision to modify allocation unit while creating the instance. This feature is available from 11.2.0.3 ASMCA.
Following environment was used to test this setup on VMWare.
Operating System : OEL 5.3 (32 bit)
Oracle Version : 11.2.0.2
Grid Infrastructure Version : 11.2.0.2
The approach would remain same for different 11.2 patchset on Linux platform.
We will NOT be covering installation of VMWare, guest OS and VMWare tools in this article. You can find lot of articles helping you to do this.
So lets start with list of tasks that needs to be done to accomplish our goal.
- Install Missing RPM packages
- Add disks at OS level for ASM
- Create oracle user and directories
- Set Kernel Parameters
- Install ASMLib and configure devices
- Install Grid Infrastructure Binaries
- Install Oracle Database Binaries
- Start CSSD service
- Create ASM Service & Instance
- Create Database Service & Instance
