HEAP

Heap dump

kill -3 [PID]                                          PID means process id

Increase Heap Size

backup set setDomainEnv.sh

 we can start editing  by below command
in linux vi  setDomainEnv.sh
---------------------------------------------------------
diff setDomainEnv.sh setDomainEnv.sh_Bala
-------------------------------------------------------------
edit /Xmx /Xms values like below by find
-------------------
/Xmx512m it will show where it is to replace. this is the differed content between  the original and backup file.

Maximum  3 Gb for the heap size.

-Xms1024m -Xmx1024m  -XX:MaxPermSize=512m this is one example to set min and max values and MaxPermSize respectively.

Xms ----------------min heap memory
Xmx ----------------max heap memory

Thread dump

To obtain a thread dump using jstack, run the following command:
jstack -l <pid>

You can output consecutive thread dumps to a file by using the console output redirect/append directive:
jstack -l <pid> >> threaddumps.log

CSR file generation

/home/sv-wl10
[sv-wl10 inddlvtwlmas01.srisohan.net~]$
$ openssl req -new -newkey rsa:2048 -nodes -keyout  inddlvtwlmas01.srisohan.net.key
-out inddlvtwlmas01.srisohan.net.key
-out inddlvtwlmas01.srisohan.net.csr

Explanation

openssl req = certificate request generating utility
-new = generates a new certificate request
-newkey = creates a new certificate request and a new private key
rsa:2048 = generates an RSA key 2048 bits in size
-nodes = if a private key is created it will not be encrypted
-keyout = the filename to write the newly created private key to
-key = specifies the file to read the private key from
-out = specifies the output filename.key
-out = specifies the output filename.csr

pack and unpack:

/apps/oracle/weblogic10.3.6/weblogic10.3.6/wlserver_10.3/common/bin

./pack.sh


-domain=/apps/oracle/weblogic10.3.6/user_projects/domain/raghu_domain
-template=/apps/oracle/domainpacks/raghu_domain.jar
-template_name=remote_managed   -managed=true

./pack.sh


=>command creates a template (a .jar archive file) that contains a snapshot of either an entire WebLogic domain or a subset of a WebLogic domain.

-domain=domain:-
=>The full or relative path for the WebLogic domain from which the template is to be created.

-template=template:-
=>The full or relative path and file name of the template to be created. The template filename must include the .jar extension.
-template_name=remote_managed

 -managed=true | false
=>Specifies whether the template is to be used to create Managed Servers on remote machines. The default is false.When this parameter is set to true, a Managed Server template is created that contains a minimal set of files, including SerializedSystemIni.dat and nm_password.properties. It also includes a domain.properties file that is unique to the Managed Server template.
Go to Middle ware home  in other machines.
/apps/oracle/weblogic12/  

./unpack.sh
-domain=/apps/oracle/weblogic1036/user_projects/domain/raghu_domain
-template=/apps/oracle/domainpacks/raghu_domain.jar

./unpack.sh


=>unpack command creates a full WebLogic domain or a subset of a domain used for a Managed Server domain directory on a remote machine.
=>unpack only with a template that is compatible with your current installation.
=>When you use the unpack command with a domain template, it creates a WebLogic domain containing all of the application and resource files defined in the template. It also creates necessary start scripts, and certain security and configuration files.
-domain=/domains/raghu_domain = domain path:-
=>The full or relative path of the WebLogic domain to be created.

-template=/apps/oracle/domainpacks/raghu_domain.jar:-
=>The full or relative path and filename of the template from which the WebLogic domain is to be created.

Delete previous log files:

find /path/to/files/ -type f -name '*.jpg' -mtime +30 -exec rm {} \;

Explanation


path/to files = where your files are located
* = wildcard
-type = file type
f = stand's for files
-name = limiting *.jpg means ending with all .jpg files OK
-mtime = how many days the files older then will be listed
+30 = files older then 30 days
-exec = executes a command
rm = is the command to remove
{} = gets the file list of all *.jpg files OK
\; = closes the command
