How to tar/untar , zip/unzip a file or directory in Linux Server

Frequently working in BI Administration, we would work on packing/unpacking the tar and zip files for installation, patching or packing the old files as backup. This command is handy and useful:

To Unpack/Untar the tar.gz file:

syntax: tar - xvzf <zip_or_tar.gz_file_Name>

e.g.: tar -xvzf  java8u251.tar.gz

The above command will untar  the java8u251.tar.gz file.

To Pack/Tar the file or directory:

Syntax: tar -cvzf <target_file_name> <source_file_Or_Directory_Name>

e.g.: tar -cvzf  jdk1.8_241.tar.gz  jdk1.8_241

How to unpack .zip file:

Unzipping in the same directory where the zip file is:

Syntax: unzip <Source_Zip_File>

e.g: unzip music.zip

Unzipping the file to a particular directory:

Syntax: unzip <source<zip_file> -d <target_directory_to_unzip>

e.g: unzip music.zip -d \home\music

How to pack .zip file:

zipping the directory:

Syntax: zip -r <target_zip_file_name> <Source_Directory>

e.g: zip -r music.zip /home/music

Zipping a file

zip names.zip names.txt

How to Unpack .zip file:

Unzipping the file to a particular directory:

Syntax: unzip <source<zip_file> -d <target_directory_to_unzip>

e.g: unzip music.zip -d /home/music

To unzip within the same directory, use the without -d

unzip music.zip

You can encrypt .zip with a password by passing the -e option:

zip -r -e music.zip /home/music

Verify file with the ls command:

ls -l music.zip

This is the meaning for each letter in -xvzf or cvzf 

• -x: Extract, retrieve the files from the tar file.
• -v: Verbose, list the files as they are being extracted.
• -c: Create, Create a tar or zip file
• -z: Zip, use gzip, zip or tar.gz to decompress the tar file.
• -f: File, the name of the tar file we want tar to work with.

Use the validaterpd Utility to Check Repository Consistency

In a development a project, we are deploying RPD multiple times and checking the RPD consistency after each deployment would be task.

We could use the Oracle BI Server validaterpd utility to check the validity of all metadata objects in a repository in command prompt.

Running this utility performs the same validation checks as the Consistency Check Manager in the Administration Tool.

The validaterpd utility is available on both Windows (validaterpd.cmd) and Linux (validaterpd.sh) systems. 

The location of the validaterpd utility is:

$BI_DOMAIN/bitools/bin

Syntax

****************

The validaterpd utility takes the following parameters:

validaterpd {-R repository_name | -I input_file_pathname |-D MDS_XML_document_directory} [-P repository_password] {-O output_txt_file_name |-C output_csv_file_name | -X output_xml_file_name} [-8] [-F fixed_rpd_name|-E] [-S] [-B]

Where:

repository_name is the name and path of the binary Oracle BI repository file that you want to validate.

input_file_pathname is the name and path of the XML input file that you want to validate.

MDS_XML_document_directory is the location of the input MDS XML documents.

repository_password is the password for the repository that you want to validate.

The repository_password argument is optional. If you don't provide the password argument, you're prompted to enter the password when you run the command. 

output_txt_file_name is the name and path of a text(.txt or .log) file where the validation results are recorded.

output_csv_file_name is the name and path of a csv file where the validation results are recorded.

output_xml_file_name is the name and path of an XML file where the validation results are recorded.

Examples

******************

The following example generates an output file called results.log that contains validation information for the repository called repository.rpd

You must provide the full path names to your repository files, both the input files and the output files, if they're located in a different directory.

./validaterpd.sh -R /home/bose/repository.rpd -O /home/bose/repository.log

Repository password: Type_Your_Repository_Password

The following example generates an output file called results.csv that contains validation information for the repository contained in the MDS XML documents located at C:\MDS_dir:

./validaterpd.sh -D C:\MDS_dir -C results.csv

Give password: my_rpd_password

Just run head -n10 of the output text, log, csv or XML file to see the first 10 lines of the results. We are good with the deployed repository if there is no errors.

$ head -n10 /home/bose/repository.log

Cheers!

Automated Cache purging in OBIEE 12c

In this post We are going to create a shell script which will purge all the cache in OBIEE. This file could  be scheduled in a cronjob OR added in informatica or ODI to run everyday once all the loads are completed or Run manually whenever you would like to run.

Step1: Create purgecache.txt file like below

Purgecache.txt
call SAPurgeAllcache()

Step2: Create a shell script to call the above file and clear the purge.

****************************************************************************************

#purgeCache12c file is created for clearing BI 12c cache#

#File Name - purgecache.sh

#!/bin/bash

#OBIEE12c Home Location

export MW_HOME=/OBIEE12c

#Location of the Purgecache script file

export SCRIPT_PATH=/OBIEE12c/scripts/purgeCache

# Timestamp for Log file creation

TIME_STAMP=`date '+%Y%m%d_%H%M'`

#Log File directory and filename creation

export LOG_FILE=$SCRIPT_PATH/purgecache_${TIME_STAMP}.log

#Mail Group that you want to send (Optional)

MAIL_LIST="#bisupport@oracle.com"

#Command to clear BI Server Cache

$MW_HOME/user_projects/domains/bi/bitools/bin/nqcmd.sh -d AnalyticsWeb -u weblogic -p weblogicpwd -s $SCRIPT_PATH/purgecache.txt -o $LOG_FILE;

# Finding Purge cache Line Count for Cache Clear success or Fail

line_cnt=`cat $SCRIPT_PATH/purgecache.txt|wc -l`

SUCCESS_FLG=`grep -E 'Operation SAPurgeAllCache succeeded' $LOG_FILE|wc -l`;

if [ $SUCCESS_FLG = $line_cnt ]

then

        echo "Cache Cleared Successfully " >> $LOG_FILE

        echo `hostname` >> $LOG_FILE

        mailx -s "Cache Clearance Successful on `hostname`" $MAIL_LIST < $LOG_FILE

else

        echo "Cache clearance Failed" >> $LOG_FILE

        mailx -s "Cache Clearance Failed on `hostname`" $MAIL_LIST << EOT

        GCWUAT Cache clearance Failed, please verify

EOT

fi

#Command to Delete the log files which is older than 5 days

find $SCRIPT_PATH/ -name "*.log" -type f -mtime +2 -exec rm -rf {} \;

**************************************************************************************

Note:

MW_HOME environment variable value should be updated based on you BI 12c environment.

You can test this script file by running manually once in your environment by the below command.

How to download Oracle Software directly in Servers using wget.sh file | How to download using wget.sh file

I often wonder that how do we download GB size of oracle softwares and move it server and Install the same until I get to know how simple is that downloading any size of software using wget.sh shell script file directly in server.

Steps are very Simple. But as a first thing, Create/Have an Oracle account for You!

Step1:

Either Oracle eDelivery or Support.oracle.com, get the wget.sh file for the software that you would like to download

Download .sh and move the file to server where you want to download.

Step2:

Open shell scripts or command prompt just run the below command

[$] ./wget.sh

enter your username: bose.obiee@gmail.com + enter

[type your password] + enter

Note:

i. Enter the same username and password which you used to download the software

ii. After entering the username, just enter it 

iii. Second line will be blank but enter the oracle account password and click enter

iv. Check if you have proper privileges with read+write+execute permission in the target directory             when you are downloading.

If it is a bigger a software then it would take sometime based on the network speed in server and will complete the download.

OBIEE 12c BIPLATFORM / MDS Account Password Expired or Account locked

I have recently come across an issue where few of our BI components went down and while stopping/restarting the services, It prompts for weblogic User Name and Password and also failing to start the services.

I have started analyzing the AdminServer log files in OBIEE 12c where I found the issue details like

[jdbc:oracle:thin:@//biapp:1521/bidev]

caused by java.sql.SQLException: ORA-28001: the password expired.

Then I understand that the supporting schemas like MDS, BIPLATFORM, IAU, OPSS and etc., accounts are expired in database. Here is the steps that how I have resolved that.

Step1: Connect to oracle database as a sys user and run the below query to get the expired accounts.

SQL> SELECT USERNAME,ACCOUNT_STATUS FROM DBA_USERS WHERE ACCOUNT_STATUS LIKE 'EXPIRED%';

Above query will result all the expired account details.

OR

SQL> SELECT USERNAME,ACCOUNT_STATUS FROM DBA_USERS WHERE USERNAME LIKE 'DEV_%'

Above query will result all the accounts starting with the name 'DEV_'

 

If you see the above screenshot, 6 accounts are expired. Lets start fixing it.

Step2: First we have to get the existing password for the expired accounts. For that run below query.

SQL> SELECT USERNAME, PASSWORD FROM DBA_USERS WHERE USERNAME = 'DEV_BIPLATFORM';

This query will give the password for only DEV_BIPLATFORM account. same like, get the password for all the accounts.

Step3: Reset the password for the account

SQL> ALTER USER DEV_BIPLATFORM IDENTIFIED BY 'Admin123';

Step4: (Optional: If any account is locked)

SQL> ALTER USER DEV_BIPLATFORM ACCOUNT UNLOCK;

Step5: Disable Password expiry

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

Note:

If you need to know the Profile name , then Please run the below Query:

SYNTAX: 

SELECT PROFILE FROM DBA_USERS WHERE USERNAME = '<USERNAME>';

E.G: 

SELECT PROFILE FROM DBA_USERS WHERE USERNAME = 'DEV_BIPLATFORM';
