Installation of EMGrid Control in same location

when getting the error message about that the



ORACLE_MIDDLEWARE_HOME_LOCATION : "/export/home/oracle/Oracle/Middleware/oms11g" subdirectory already exists in oracle inventory: specify another home location.

try this:


/etc/oratab

and also you have to remove following four entries from each of directories that stores inventory information:

Locate your central inventory directory from /etc/oraInst.loc
inventory_loc=/u00/app/oraInventory

ls -l
backup
ContentsXML

cd ContentsXML
vi inventory.xml

delete all the entries for

#
#
#
#

Also note that under directory Backups, there are further directories and you need to remove these entries from each and every inventory.xml.

cd backup

grep -i inventory */*/in*

once you remove all the entries.

Go to your location where you have installed Middleware.

in my case
cd /u00/app/oracle/product/11.2.0/Middleware.

rm -rf oms11g agent11g oracle_common Oracle_WT.

EM Configuration issue. $ORACLE_HOME/odprimary_PRIDB not found

oracle control 12c agent issue

root cause

A common cause for this error is changing the hostname of the server in either /etc/hosts or DNS. In this case the there were no changes to the hostname as we were able to connect to the hostname listed in the last known state on the database home page.

Resolution

changing /etc/hosts to the following:
127.0.0.1 localhost.localdomain localhost
172.17.100.250 cloudcc12c cloudcc12c.com

Public Yum Server

Last updated: 9 May, 2011
Introduction

The Oracle public yum server offers a free and convenient way to install packages from the Oracle Linux and Oracle VM installation media via a yum client.

You can download the full Oracle Linux and Oracle VM installation media via edelivery.oracle.com/linux. Note that errata are not available via this public yum server. To access errata (bug fixes, security fixes and enhancement), you must have a valid support contract to access Unbreakable Linux Network (ULN). For more information, see the FAQ below.

This yum server is offered without support of any kind. If you require support, please consider purchasing Oracle Linux support via the online store, or via your sales representative.
Getting Started

Download and Install Oracle Linux

Download and copy the appropriate yum configuration file in place, by running the following commands as root:
Oracle Linux 4, Update 6 or Newer

# cd /etc/yum.repos.d
# mv Oracle-Base.repo Oracle-Base.repo.disabled
# wget http://public-yum.oracle.com/public-yum-el4.repo

Oracle Linux 5

# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo

Oracle Linux 6

# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ol6.repo

Oracle VM 2

# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-ovm2.repo

Enable the appropriate repository by editing the yum configuration file
Open the yum configuration file in a text editor
Locate the section in the file for the repository you plan to update from, e.g. [el4_u6_base]
Change enabled=0 to enabled=1

Begin using yum, for example:

yum list

yum install firefox
