ODI-1545: Missing odi supervisor credentials in credential store map

Posted on by Osama Mustafa in Fusion Middleware
This Error appear because missing SuperVisor User Credentials, and you need to create it using wls.sh command, And Since we are working On Oracle_ODI So you have to use WLST.sh from there.

cd /u01/app/fmw/Oracle_ODI1/common/bin
./wlst.sh

and do the below

Jython scans all the jar files it can find at first startup. Depending on the system, this process may take a few minutes to complete, and WLST may not return a prompt right away.

Create Group using Em12c

Posted on by Osama Mustafa in Application
Sometimes you need to create Certain group for Enterprise manager to make monitor more easy , sepcially if you have lot of agent and components such as database , Host , application server … so if you want to manage them individually it will consume time and seems to be impossible.

Enterprise manager provide you with Group Features to combine components, and there’s two type :

  • Target at the same type 
  • Target contain different components such as database, Application server , Host.

Check the below screenshot :

From Setup –> Add Target –> Group

you have five tab each one of them contain different parameters, Choose the right option that works with your Work:

After Choose the name for the group you need to add Agents, from search button new popup screen will be open choose which agent type you want.

unpack.sh Error -name=Value

Posted on by Osama Mustafa in Fusion Middleware
The pack command creates a template archive (.jar) file that contains a snapshot of either an entire domain or a subset of a domain. You can use a template that contains a subset of a domain to create a Managed Server domain directory hierarchy on a remote machine.

The unpack command Creates a full domain or a subset of a domain used for a Managed Server domain directory on a remote machine. You may use unpack only with a template compatible with your current installation. The template can be any of the following:

  •  A domain template provided by BEA and packaged with your current installation
  •  A domain template created using the Domain Template Builder or WLST Offline
  •  A domain template created using the pack command
  •  A Managed Server template created using the pack command. A Managed Server template, by default, contains only the files necessary for creating a Managed Server domain directory.
You Can Check Oracle Documentation here for more information about the above commands.
When Trying to use unpack command with the below command:

./unpack.sh -domain=/u01/app/oracle/domains/IDMDomains -template=/u01/shared/IDMdomains.jar

The below error appear :

ERROR !!! ./unpack.sh -name=Value Missing

The Solution is simple :

-template attribute should come first. 

./unpack.sh  -template=/u01/shared/IDMdomains.jar -domain=/u01/app/oracle/domains/IDMDomains

You need to know some  Definition you will heard when we are talking about Cloud:
Xaas is Term said for number of things “X as a Services” / ” Anything as a Services”

The Most Common Examples on the above :
