What is BAR?
BI Application Archive (BAR) files are zipped-up copies of the RPD, Catalog and Security model metadata from a Service Instance.
When deploying your BI application from one server to another you can now use these BAR files to transfer your metadata rather than
transferring the RPD, catalog and security model separately.
It’s also a simple method of taking point in time backups of your application.

Steps to export and import BAR files in OBIEE 12C
Step 1:
Go to
C:\Oracle\Middleware\Oracle_Home\oracle_common\common\bin
Run wslt.sh script
Step 2:
To view List of
serviceinstaces use the wslt command listBIServiceInstances(domainhome)
Run listBIServiceInstances('C:/Oracle/Middleware/Oracle_Home/user_projects/domains/bi')
wls:/offline>
listBIServiceInstances('C:/Oracle/Middleware/Oracle_Home/user_projects/domains/bi')
Exporting BAR files
Note:
4 main Parameters for exporting and importing bar files
1.DOMAIN_HOME (<obiee_home>/user_projects/domains/bi)
2.Serive Instance key the instance key of the BI
service you are intercating with
3.Working directory Where
export command will store files temporarily while exexutingth eprocess
4.Export directory Is
the directory where BAR files will be stored
Step 3:
Create working directory and export directory
My working directory is: /C:/workDir
My export directory is: /C:/exportDir
Service instance key: ssi
Run below command:
exportServiceInstance(domainhome,service_instance key,
working dir path, export dir path)
exportServiceInstance('C:/Oracle/Middleware/Oracle_Home/user_projects/domains/bi','ssi','/C:/workDir','/C:/exportDir')
Step 4:
Verify exportDir
Importing of BAR files
While importing BAR files we can choose whether to import
all three components (RPD,Catalog,Security model) or just selected elements.
importServiceInstance command Parameters:
- · DomainHome
- · Service instance key
- · BAR file to import
- · IMPORT THE rpd
- · Import the webcat
- · import the security model
- · Include credentials (This is passowrd used to encrypt the database connectioncredentials in the RPD.
Note:
First 3 parameerts are
mandatory
😉
Command :
importServiceInstance(DomainHome,Service Instance Key,BAR
file to import)
Run below command:
importServiceInstance('/u01/app/obiee/user_projects/domains/bi','ssi','/u01/importDir/ssi.bar')
Above command import the RPD, catalog and security model,
but not the user runtime info. The connection credentials would not be
imported(if they are even in the file)
importServiceInstance('/u01/app/obiee/user_projects/domains/bi','ssi','/u01/importDir/ssi.bar',true,true,true,'Password')
Above command will import RPD,Catalog an dsecurity model and run
time user information also. This is the best command while deploying from development
to Production environment.
importServiceInstance('/u01/app/obiee/user_projects/domains/bi','ssi','/u01/importDir/ssi.bar',true,true,false,'Password')
Above command will import RPD,catalog,but it will not import
security model or run time user information.

The effectiveness of IEEE Project Domains depends very much on the situation in which they are applied. In order to further improve IEEE Final Year Project Domains practices we need to explicitly describe and utilise our knowledge about software domains of software engineering Final Year Project Domains for CSE technologies. This paper suggests a modelling formalism for supporting systematic reuse of software engineering technologies during planning of software projects and improvement programmes in Final Year Projects for CSE.
ReplyDeleteSoftware management seeks for decision support to identify technologies like JavaScript that meet best the goals and characteristics of a software project or improvement programme.

I can’t believe focusing long enough to research; much less write this kind of article. You’ve outdone yourself with this material without a doubt. It is one of the greatest contents. Shipping Containers for sale Brisbane
