How to Delete a deployment manually from WebLogic server using wlst offline mode

Steps to delete a deployment(WAR, EAR, JAR) manually through wlst offline mode
Step 1: Set the Weblogic environment by executing the script:- setWLSEnv.sh

[root@pbifmssso ~]# cd /opt/Oracle/Middleware/wlserver_10.3/server/bin

[root@pbifmssso bin]# sh setWLSEnv.sh

CLASSPATH=/opt/Oracle/Middleware/patch_wls1035/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/opt/Oracle/Middleware/patch_ocp360/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/opt/jdk1.6.0_25/lib/tools.jar:/opt/Oracle/Middleware/wlserver_10.3/server/lib/weblogic_sp.jar:/opt/Oracle/Middleware/wlserver_10.3/server/lib/weblogic.jar:/opt/Oracle/Middleware/modules/features/weblogic.server.modules_10.3.5.0.jar:/opt/Oracle/Middleware/wlserver_10.3/server/lib/webservices.jar:/opt/Oracle/Middleware/modules/org.apache.ant_1.7.1/lib/ant-all.jar:/opt/Oracle/Middleware/modules/net.sf.antcontrib_1.1.0.0_1-0b2/lib/ant-contrib.jar: PATH=/opt/Oracle/Middleware/wlserver_10.3/server/bin:/opt/Oracle/Middleware/modules/org.apache.ant_1.7.1/bin:/opt/jdk1.6.0_25/jre/bin:/opt/jdk1.6.0_25/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/opt/jdk1.6.0_25/bin Your environment has been set.

Step 2: Change the directory path to WL_HOME/common/bin

[root@pbifmssso bin]# cd /opt/Oracle/Middleware/wlserver_10.3/common/bin

Step 3: Run the command sh wlst.sh

[root@pbifmssso bin]# sh wlst.sh

Welcome to WebLogic Server Administration Scripting Shell Type help() for help on available commands wls:/offline>

Step 4: Execute the command as below to remove the deployment say CookieApp from the weblogic Admin server t3://192.168.20.57:7001

>connect(‘weblogic’,'WebL0gic@tcs2011’,'t3://192.168.20.57:7001')

>edit() 

>startEdit() 

>undeploy(‘CookieApp’)

>save()
>exit()
>activate() 

Finally the application CookieApp get deleted, restart the server to remove the cache and tmp folder.

How to Find Out Top Files (Disk Space) in Linux?

If you want to display the biggest file sizes only, then run the following command:

# find -type f -exec du -Sh {} + | sort -rh | head -n 5

To find the largest files in a particular location, just include the path besides the find command:

# find /home/tecmint/Downloads/ -type f -exec du -Sh {} + | sort -rh | head -n 5
                                                                      OR
# find /home/tecmint/Downloads/ -type f -printf "%s %p\n" | sort -rn | head -n 5

The above command will display the largest file from /home/tecmint/Downloads directory.

How to Find Out Top Directories and Files (Disk Space) in Linux

Run the following command to find out top biggest directories under /home partition

# du -a /home | sort -n -r | head -n 5

The above command displays the biggest 5 directories of my /home partition.

If you want to display the biggest directories in the current working directory, run:

# du -a | sort -n -r | head -n 5

Let us break down the command and see what says each parameter.

du command: Estimate file space usage.
a : Displays all files and folders.
sort command : Sort lines of text files.
-n : Compare according to string numerical value.
-r : Reverse the result of comparisons.
head : Output the first part of files.
-n : Print the first ‘n’ lines. (In our case, We displayed first 5 lines).

Some of you would like to display the above result in human readable format. i.e you might want to display the largest files in KB, MB, or GB.

# du -hs * | sort -rh | head -5

The above command will show the top directories, which are eating up more disk space. If you feel that some directories are not important, you can simply delete few sub-directories or delete the entire folder to free up some space.

To display the largest folders/files including the sub-directories, run:


# du -Sh | sort -rh | head -5

Find out the meaning of each options using in above command:

du command: Estimate file space usage.
-h : Print sizes in human readable format (e.g., 10MB).
-S : Do not include size of subdirectories.
-s : Display only a total for each argument.
sort command : sort lines of text files.
-r : Reverse the result of comparisons.
-h : Compare human readable numbers (e.g., 2K, 1G).
head : Output the first part of files.

Script to get the CPU utilization status of any process running on a linux system

Steps to get the CPU utilization status of any process running on a linux system

1.Copy and paste the below code onto the linux server using vi editor

$ cd /tmp/scripts/

$ vi cpuUtilization.sh

#!/bin/sh

var1=`ps -ef | grep Dweblogic.Name | grep Server_1| awk '{print $2}'`

var2=` ps -ef | grep Dweblogic.Name |grep Server_2|awk '{print $2}'`

time=`date +%d-%m-%y-%H:%M:%S`


ps -eLo pid,ppid,tid,pcpu,comm | grep "$var1" > /u01/apps/oracle/Server_CPU_Utilization/Server_1_"$time"

ps -eLo pid,ppid,tid,pcpu,comm | grep "$var2" > /u01/apps/oracle_oc/Server_CPU_Utilization/Server_2_"$time"

2. Now set a cronjob to get the script executed automatically after a specified interval say 5 mins

$ */5,* * * *  /tmp/scripts/cpuUtilization.sh

3. The output of the script would be append to the files at the location

/u01/apps/oracle/Server_CPU_Utilization

Note: Steps to set cronjob “At every 5th minute.”
