Cognos 8 Installation with oracle 9.2 and IIS


1. Install Cognos 8 -
Cognos 8 normally comes in 2 differenct forms-
Cognos 8 with Metrics Studio
Cognos 8 without Metrics Studio
Cognos 8 without Metrics studio has 2 CDs. First one contains CRN server setup and the second one cotains Framwork Model and content store setup.
2. Update the Java Environment
Cognos 8 cryptographic services use specific .jar (Java Archive) files in your Java RuntimeEnvironment (JRE) to determine the allowed strength of the JRE. Cognos 8 provides the necessary jurisdictional policy .jar files in case your JRE does not have the minimum require cryptographic strength.If you do not have a JAVA_HOME variable already set on Windows or if JAVA_HOME points toa Java version that is not valid for Cognos 8, the JRE files provided with the installation will beused, and you do not have to update any files in your environment.If you want to use your own JRE and have JAVA_HOME set to that location on Windows or ifyou are installing on UNIX, you may have to update the Java environment for the cryptographicservices.The need to update your Java environment depends on the relative strength of jurisdictional policy.jar files in your environment. For example, if you already have stronger files in your environment than are provided with Cognos 8, you do not have to update the environment. Doing so, in this case, may cause other applications to not work correctly.If you update your Java environment, it is recommended that you make a backup copy of the files you overwrite. If other applications fail, you may have to replace the original jurisdictional policy.jar files.On Windows, you can set JAVA_HOME as a system variable or a user variable. If you set it as asystem variable, it may be necessary to restart your computer for it to take effect. If you set it as a user variable, set it so that the environment in which Tomcat is running can access it.Java 1.3.1 is the minimum supported JRE for Cognos 8. Ensure that you installed the correct JRE for the hardware that you are using. The encryption .jar files provided with the installation are for Java 1.4.2. These file will not work with Java 1.3.1
1. Ensure that the JAVA_HOME environment variable is set to the JRE location.
2. Copy the following files from the c8_location/bin/jre/version/lib/security directory to theJava_location/version/lib/security directory:
• local_policy.jar
• US_export_policy.jar
3. Copy the bcprov-jdk13-125.jar file from the c8_location/bin/jre/version/lib/ext directory tothe Java_location/version/lib/ext directory.
4. If you use Sun JRE 1.4.2 on UNIX, ensure that you are using the correct startup file for the/dev/random device.You must use /etc/init.d or /etc/rc3.d/f20random.For more information, see your UNIX documentation.
3. Create virtual directories in IIS
Create Below 2 virtual direcotories in IIS-cognos8 which points to the location 'c8_location/webcontent' and has 'Read' permissionIn the above virtual directory create one more virtual direcotry cgi-bin pointing to location 'c8_location/cgi-bin' with 'Execute' permission.
4. Create content store in Oracle
steps -
On the computer where Oracle is installed, go to the ORACLE_HOME/jdbc/lib directory
Copy the classes12.jar file to the c8_location/webapps/p2pd/WEB-INF/lib directory on the Cognos 8 computers where the software must be installed.
Create a user in Oracle who has DBA privilege (user 'system' can also be used as it has DBA privileges). For this first login to the system with user 'system' and then write below SQL- create user identified by ; grant dba privileges to ;
Open Cognos Configuration
Go to Content Manager and delete existing content store( which points to MS SQL Server by default.)
Right click on Content Manager and create new Content Store
Select Oracle as database
Specify service name, user name and password
Test the connection
Save the updated configuration
5 Start the service from cognos configuration
6 Open the URL from the local system by using URL- "
