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