To make sure no other process is running kill nodemanager and obiee processes
ps -ef |grep Node|grep nodemanager |cut -c10-15
ps -ef |grep obiee
Kill the above processes ( kill <PID>)

Stopping Weblogic

Go to
<OBIEE Home>/user_projects/domains/bifoundation_domain/bin/
Then run -> ./stopWebLogic.sh

Starting Weblogic
---------------
nohup sh
<OBIEE Home>/user_projects/domains/bifoundation_domain/bin/startWebLogic.sh -Dweblogic.management.username=weblogic -Dweblogic.management.password=weblogic234 > wls_start.log &
Note: Change password of your application. Nohup is the command to run the process in the linux and give the control back to putty.

Starting NodeManager
------------------
nohup sh  <OBIEE Home>/wlserver_10.3/server/bin/startNodeManager.sh > startNodeManager.log &

Starting EM
------------

nohup sh <OBIEE Home>/user_projects/domains/bifoundation_domain/bin/startManagedWebLogic.sh bi_server1
Note: bi_server1 is the server name. make sure your server name given properly

How to Increase no of rows in excel output in OBIEE

To use Fusion Middleware Control to set configuration options for views:

Go to the Business Intelligence Overview page, as described in Section 2.2.3, "Using Fusion Middleware Control to Manage Oracle Business Intelligence System Components."

Display the Performance tab of the Capacity Management page.

Click Lock and Edit Configuration to enable changes to be made.

Complete the elements using the descriptions in the help topic for the page. Click the Help button on the page to access the page-level help for the following options:

Click Apply, then click Activate Changes.

Return to the Business Intelligence Overview page and click Restart.


Method 2:

To manually edit the settings that change the display of data in views:

Open the instanceconfig.xml file for editing, as described in Section 3.6, "Where Are Configuration Files Located?"

Locate the Table, Pivot, Trellis, Charts, Narrative, Ticker, and Treemap parent sections, in which you must add the elements that are described in Table 19-2.

Include the elements and their ancestor elements as appropriate, as shown in the following example:

1. Take a back up copy of <Middleware_Home>/instances/instance1/config/OracleBIJavaHostComponent/coreapplication_obijh1/xdo.cfg file.

2. Open xdo.cfg for editing.

3. Add the following:
(Setting "xlsx-keep-values-in-same-column" to true)

<config version="1.0.0" xmlns="http://xmlns.oracle.com/oxp/config/">
<properties>
<property name="xlsx-keep-values-in-same-column">true</property>
</properties>
</config>

connection failed while importing metadata in obiee 11g

There are many reasons you may get this error. One way to resolve the issue is to correct the shortcut which is placed on the desktop

Go to the Installed path of the Admin tool. 

In my case it is 

C:\Program Files\Oracle Business Intelligence Enterprise Edition Plus Client Tools\oraclebi\orahome\bifoundation\server\bin\

Find Admintool.exe and create a shortcut by using right click and paste the below value

"C:\Program Files\Oracle Business Intelligence Enterprise Edition Plus Client Tools\oraclebi\orahome\bifoundation\server\bin\bi_init.bat" coreapplication admintool.exe

Make sure that (“) didn’t miss.

Note: tnsnames.ora file should be kept in the repository folder from where you are opening the rpd. This file you can get it from Oracle database from the server under network folder.
