Oracle Analytics Server 7.0.0.0.0 is Available for Download

 After OAS 5.5, 5.9 and 6.4, Now Oracle has release OAS 7.0.0.0 and it is available for download and Install.

OAS 7.0 Home Page: 

https://www.oracle.com/solutions/business-analytics/analytics-server/analytics-server.html

Searching a log files in Linux

 Being a Developer and Administrator, It is our everyday duty to analyze log files of bi server, scheduler, presentation or nodemanager log. 

When logs are growing, it is difficult to identify and track it. For e.g: When hundred Agents are scheduled, it is creating 200 files everyday with .log and .err files in scheduler log location. 

When you want to search yesterday or today or 10 days before with the particular agent log file, the following syntax will help you to bring up the files.

[logs]$ find . -iname "Agent-111-*" -atime -2 -type f -ls

The above syntax will list out all the files starts with Agent id 111 before 2 days.

Customize the syntax based on your need.

Cheers!

Oracle Analytics Server Step by Step Installation in Windows | OAS 5.5 Installation in Windows

Surprisingly Oracle has released OAS for windows and I gave a try to install OAS 5.5 in windows to check out the look and features. This post has the steps how I have installed OAS 5.5 in windows.

Prerequisite:

1. Java JDK1.8 221 or Above. (Step by Step installation of Java)

2. Oracle Database 11g Release 2 and above. (Step by step Installation of Oracle DB 12c)

3. I would highly recommend to have minimum of 16 GB Memory and 50GB Disk Space to Install in your windows machine.

OAS 5.5 has 4 Major stages of Installation in Windows

1. Oracle Fusion Middleware Installation

2. OAS Platform Installation

3. RCU (Repository Creation Utility) 

4. OAS Configuration

Note: Interim FMW Patch is only for Linux and not required for Windows. 

Download the OAS 5.5 software's files and extract it in a folder.

Download Link: 

https://www.oracle.com/solutions/business-analytics/analytics-server/analytics-server.html

Check if JAVA_HOME and ORACLE_HOME  variable are set in Environment variable. If it is not set, then Create the environment variable.

example: 

JAVA_HOME=C:\Program Files\Java\jre1.8.0_271

ORACLE_HOME=C:\oracle\app\oracle\product\11.2.0\db_1

Step1: Oracle Fusion Middleware Installation

Open the Command Prompt with 'Run as administrator' and go to JAVA bin location to start the fusion middleware installation. The whole OAS installation going to be done in command prompt with the same manner.

cd C:\Program Files\Java\jre1.8.0_271\bin

C:\Program Files\Java\jre1.8.0_271\bin> java -jar D:\OAS\fmw_12.2.1.4.0_infrastructure.jar

It will check the prerequisite and starts the installation. Just click 'Next' with the below screen.

Select the installation directory where you want to install OAS.

Just keep the default selection 'Fusion Middleware Infrastructure' and Click 'Next'

Now the installer checks the system certification and java version. Just click 'Next'

With this step, I have saved the response file for silent installation. If you don't want, then just click 'Install' to start the installation of OAS FMW.

Just click 'Install'.

Save response file if you would like to use it later for silent installation in another environment.

OAS FMW installation is in progress....

If all the steps are successful, it will complete with 100%. Just click 'Next' Here

We have come to the last step of OAS FMW installation. Just click 'Finish' the complete the installation.

In this step, select your Oracle Home from your fusion middleware directory and click 'Next'. Here I created my own directory OAS55 in D drive and selected that directory.

With the below step, Save response file if you would like to use it for silent installation in any other system. otherwise just click 'Install'

Installation is in progress......
