Execute commands remotely from unix shell

 

The ssh command on linux does not support passing the passwords at the command line ,

You need to use the sshpass command. It is a utility designed for running ssh using the mode referred to as "keyboard-interactive" password authentication, but in non-interactive mode. You can install it as follows:

rpm –ivh ftp://ftp.muug.mb.ca/mirror/fedora/epel/5/i386/sshpass-1.05-1.el5.i386.rpm

sshpass -p 'root-password' ssh -o StrictHostKeyChecking=no  root@localhost " du  --exclude=/shared  --exclude=/shared2 -Sm / | sort -nr | head -10"

sshpass -p 'root-password' ssh -o StrictHostKeyChecking=no  root@localhost " uptime "

Steps to Apply the JDeveloper stand alone patches

 

First download the standalone opatch using the patch number  5912518.
Assuming my JDev Home is : d:\fmw1115\Middleware\jdeveloper
copy d:\p5912518_111000_GENERIC.zip cd d:\fmw1115\Middleware\jdeveloper
cd d:\fmw1115\Middleware\jdeveloper
unzip -d . p5912518_111000_GENERIC.zip
set  ORACLE_HOME=d:\fmw1115\Middleware\jdeveloper
set PATH=d:\fmw1115\Middleware\jdeveloper\OPatch;%PATH%
cd C:\temp\13607268
First try ,
opatch version -jdk d:\fmw1115\Middleware\jdk160_24
Invoking Standalone OPatch 11.1.0.0.0
OPatch Version: 11.1.0.0.0
OPatch succeeded.
Now Apply the patch using ,
opatch apply -jdk d:\fmw1115\Middleware\jdk160_24
If you are applying the patch for the first time then you will see ,
> OPatch finds no 'product.xml' in Oracle Home and will attempt to create 'product.xml' file.
>
> Attempting to retrieve patch inventory's "product" and its "version" information...
>
> Please enter your choice to enable OPatch to create 'product.xml' file or quit creation...
>
>
> Choice Product Version
> ------ ------- -------
> 1 SA_JDEV 11.1.1.5.0
>
> 2. If you wish, quit 'product.xml' creation
>
> Please enter [1-2]:
> 1
> User Responded with: 1
>
> OPatch will put the information of selected product 'SA_JDEV' and selected version '11.1.1.3.0'
> in product.xml during inventory updation.
> "
Now run the command to verify whether the patch applied or not ,
C:\temp\13607268>opatch lsinventory -jdk d:\fmw1115\Middleware\jdk160_24
To remove the patch  run the command ,
cd C:\temp\13607268
opatch rollback -id 13607268 -jdk d:\fmw1115\Middleware\jdk160_24

How to measure the time it takes to load a web page

 

Many times you need to find out the how long a web page takes to load when troubleshooting performance related
problems.

Here are the steps that you can use with the WebLogic Server 11g.

Home >Summary of Servers >AdminServer
Click on Loggin TAB -> HTTP and go to the Advanced Options

Select the Format as "Extended"
and add the field " time-taken" to the Extended Logging Format Fields.
For example after adding it will be
"date time cs-method cs-uri sc-status time-taken"

After this you need to restart the Server ,

This is the WLST script to do the same ,

connect('weblogic', 'Welcome1', 't3://localhost:7001')
startEdit()

cd('/Servers/AdminServer/WebServer/AdminServer/WebServerLog/AdminServer')
cmo.setLogFileFormat('extended')
cmo.setELFFields('date time cs-method cs-uri sc-status time-taken')

activate()
disconnect()
exit()

After this you need to restart the Server ,

Check the access_log file entries ,

2012-03-09      14:19:16        GET     /em/faces/targetauth/emasLogin?target=Farm_soa_domain&type=oracle_ias_farm&FromContextInitFilter=true&_afrLoop=18992901037066&_afrWindowMode=0&_afrWindowId=null    200     0.066
2012-03-09      14:19:20        GET     /em/LoginStatusServlet?loginReqTime4emas=rlt_1331282958512_0.31560349677888955  2000.0040

The last column indicates the time.

You can measure the timings from browser also ,

for this use the FireFox version > 4.0 , here you can use the Tools-> Web Console or Tools -> Web Developer -> Web Console option.

Or you can use the fiddler tool to measure the time it takes to load web page ,
download the fiddler from ,
http://fiddler2.com/fiddler2/

Fiddle tool can be used with IE or firefox.

Unable to start the WebLogic Server weblogic.security.SecurityInitializationException: Authentication for user weblogic denied

 

Getting the following exception when trying to start the WebLogic Server

Follow the following steps:
1: remove the boot.properties file completely from the managed server directory.
2: remove the ManagedServerDir/data/ldap directory completely.
3: Always keep backup of files before removing it.
4: Now try to start the server from the command prompt and provide the username/password used to login to the Admin Console.
