The DataPower capabilities are delivered in a network appliance form factor:

Physical appliances

• XG45: DataPower Service Gateway
• XI52: DataPower Integration Appliance
• XB62: DataPower B2B Appliance

DataPower form factors Virtual appliances (under a hypervisor)

• XG45/XI52 Virtual Edition
• Production
• XG45/XI52 Virtual Edition for Nonproduction Environment
• Multi-user test and development
• XG45/XI52 Virtual Edition for Developers
• Single-user test and development

Network interfaces for virtual appliances

• Physical appliances have 8 (XG45) or 12 (XI52, XB62) Ethernet interfaces
• Virtual appliances have four network interfaces:
• eth0, eth1, eth2, eth3
• Speeds depend on hypervisor and hardware
• Physical mode and flow control settings are ignored
• Hypervisors that the IBM PureApplication System manages allow only eth1-3 to be used for DataPower service configuration
• eth0 is used by IBM PureApplication System management
• All other hypervisor environments allow eth0-3 to be used for service configuration

Deployment on stand-alone VMware hypervisors

Login to the appliance

login: admin

 

password: admin

 

Enable Secure Backup Mode

Secure backup mode supports the creation of a backup to restore the complete configuration of another DataPower® Gateway. The creation of a secure backup is available only when secure backup mode is enabled. Generally, secure backup mode is enabled during the initial firmware setup of the DataPower Gateway

 

Confirn Enable Secure Backup Mode

Enable Common Compatibility Mode

When the DataPower Gateway is in Common Criteria Compatibility mode, it forces several settings to specific values. These values are required and enforced at restart. Common Criteria Compatibility mode affects audit log policies, password policies, and includes a group of default rules and actions.

Create new admin password

Please Enter New Password to be used in next login

Run the Install Wizard

Step 1 - Confirure network interfaces

Do you want to confirure network interfaces

Do you want to confirure network interfaces answers to do

1. Start configuring the first network interface
1. Enable the DHCP
2. Don't configure the rest network interfaces

Step 2 - Configure network service

Step 3 - Define a unique system identifier for the appliance

Sometimes there is a need to have an identifier that is unique per DataPower device. Typically the device serial number is taken for these purposes.

Note: Give any appropriate unique system identifier.

Step 4 - Do you want to configure remote Management access

These configuration require the IP address of the local interface that manage the appliance.

Do you have this information? [y]: y
Do you want to enable SSH? [y]: y
Enter the local IP address [0 for all] : 0
Note: In case you provide specific IP earlier, Provide same IP as provided earlier.

Enter the port number [22]:
Note: Just enter to accept default or write your needed port

Do you want to enable WebGUI access [y]: y

The WebGUI is one of the graphical user interfaces that the DataPower Gateway provides. The Blueprint Console is the one of the graphical user interface (GUI) for the DataPower Gateway. The Blueprint Console allows you to create and manage patterns and tenants.

Enter the local IP address [0 for all] : 0
Note: Just enter to accept default or write your needed port
Enter the port number [9090]:
Note: Just enter to accept default or write your needed port

Step 5 - Configure a user account that can reset passwords

Step 6 - Configure the RAID array

Save the current configuration

Access the configured device

Show int

The show ip interface command provides tons of useful information about the configuration and status of the IP protocol and its services, on all interfaces. The show ip interface brief command provides a quick status of the interfaces on the router, including their IP address, Layer 2 status, and Layer 3 status

VirtualBox and Docker Won’t Run | Because of Windows 10 Hyper-V?

I managed to resolve the issue but not by uninstalling Hyper-V. I saw a couple of suggestions but I find this one suitable:

STEP 1:
Open the command prompt as an Administrator.

STEP 2:
Run the command with no argument:
bcdedit

After you run the above command, you will see that the property hypervisorlaunchtype is set Auto by default. See screenshot below:


STEP 3:
Disable Hyper-V by running the command:
bcdedit /set hypervisorlaunchtype off

STEP 4:
Restart your PC system to use VirtualBox.

To turn Hyper-V back on, run the command:
bcdedit /set hypervisorlaunchtype auto
You will need to reboot the system to use Hyper-V.

Docker | Windows 10/ Mac OS | unauthorized: incorrect username or password when trying to pull images

It happens because the docker client (on macOS or Windos 10) allows you to sign in with your email address and password. If you sign out and sign in with your Docker Username and password everything will work. So here's a better description of the issue

Description
When trying to pull images from the Docker registry docker: Error response from daemon: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: unauthorized: incorrect username or password. This happens if you sign in to Docker using your email address instead of your username.

Steps to Reproduce

1. Clean install, or reset preferences for Docker
2. Sign in to Docker GUI using your email address and password
3. In the terminal, pull an image from the Docker registry

Actual Results
docker: Error response from daemon: Get https://registry-1.docker.io/v2/library/hello-world/manifests/latest: unauthorized: incorrect username or password.

Solution 

Try logging back in with the CLI via docker login

What is the difference between 'git pull' and 'git fetch'?

In the simplest terms, git pull does a git fetch followed by a git merge.

You can do a git fetch at any time to update your remote-tracking branches under refs/remotes/<remote>/.

This operation never changes any of your own local branches under refs/heads, and is safe to do without changing your working copy. I have even heard of people running git fetch periodically in a cron job in the background (although I wouldn't recommend doing this).

A git pull is what you would do to bring a local branch up-to-date with its remote version, while also updating your other remote-tracking branches.


git pull = git fetch + git merge.

Warning Message cannot validate component with empty value

"BeanValidator W cannot validate component with empty value: xxxComponent" is generated in server console logs coming from javax.faces.validator.BeanValidator class with JSF2.1 for multiple components. 

Error Messages

BeanValidator W cannot validate component with empty value: xxxComponent

Steps to Reproduce

Use any component without binding to bean variable and use the value from FacesContext, RequestParameterMap in bean or phase listener

Root Cause

A third-party product issue with Trinidad. This happens when the Trinidad tag is missing the value attribute. The value attribute binds between the input and the bean.  

Resolution

On binding the component with bean variable, the warning message does not appear in the logs. 

If there are no functionality issues while executing the custom use case then these warning messages can be ignored. Alternatively, the logging can be configured to Severe level such that it is not logged in the server log. Configuring warning message related to JSF2 has been documented in Chordiant_JSF guide, page number-46. Refer the below text snippet: 

Note: To disable JSF 2.0 warnings from displaying at the server startup, add the properties org.apache.myfaces.level = SEVERE and javax.faces.validator.level = SEVERE in the default Java logging.properties file located in JAVA_HOME/jre/lib. 

How to rename terminal tab title in Ubuntu 16?

A lot of programs will overwrite the title so you can't rely on the title being fixed or not duplicated by other windows. This is especially so with remote ssh sessions in a gnome-terminal.
It still helps a lot but its not reliable enough for window managers to do matching against , so this ability has been taken out with the newest gnome-terminal, however there is still a possibility to change the title, you can do it by command.

To achieve this easily edit your ~/.bashrc file and add the following lines:

 
Create a function in ~/.bashrc:

function set-title() {
  if [[ -z "$ORIG" ]]; then
    ORIG=$PS1
  fi
  TITLE="\[\e]2;$*\a\]"
  PS1=${ORIG}${TITLE}
} 

Then use your new command to set the terminal title. It works with spaces in the name too

set-title my new tab title 

With this you then can set the title of your terminal window by simply using the command set-title <name you want to set it to>. This is possible due to ANSI escape codes so any program can output them regardless of where the code is run. 

Ubuntu - How do I change my username?

Unix-like operating systems decouple the user name from the user identity, so you may safely change the name without affecting the ID. All permissions, files, etc are tied to your identity (uid), not your username.

To manage every aspect of the user database, you use the usermod tool.

1- To change username (it is probably best to do this without being logged in):

sudo usermod -l newUsername oldUsername

This however, doesn't rename the home folder.

2- To change home-folder, use

sudo usermod -d /home/newHomeDir -m newUsername

after you changed the username.

For instance, you could logout, drop to a console (Ctrl+Alt+F1), and sudo su - to become true root (as opposed to sudo -s, where $HOME is still /home/yourname.) Maybe you also have to kill some still running processes from this user first. To do so, enter ps -u username, look for the matching PID and kill them by kill PID-number.

Update: as arrange mentioned, some files may reference your old home directory. You can either keep a symlink for backward compatibility, e g ln -s /home/newname /home/oldname or you can change the file contents with sed -i.bak 's/*oldname*/*newname*/g' *list of files* It creates a backup for each file with a .bak extension.

Some additional information for not so experienced users like me:
As I only have ONE user account (administrator), it would not let me change the username ("you are already logged in" was the response in TTY1 (Ctrl+Alt+F1). To get around this:

1. Login with your old credentials and add a new user, e.g. "temporary" in TTY1:
   

   sudo adduser temporary
   

   set the password.
2. Allow the temporary user to run sudo by adding the user to sudo group:
   

   sudo adduser temporary sudo
   

3. Log out with the command exit.
4. Return to tty1: Login with the 'temporary' user account and password. Change your username and folder as mentioned above. exit (until you get the login prompt)
5. Go back to TTY7 (Ctrl+Alt+F7) to login on the GUI/normal desktop screen and see if this works.
6. Delete temporary user and folder:
   

   sudo deluser temporary
   sudo rm -r /home/temporary

Mac OS X - Reset MySQL Root Password

Have you forgotten your Mac OS X 'ROOT' password  and need to reset it?  Follow these 4 simple steps:

1.  Stop the mysqld server.  Typically this can be done by from 'System Prefrences' > MySQL > 'Stop MySQL Server'

2.  Start the server in safe mode with privilege bypass

     From a terminal:

     sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables

3.  In a new terminal window:

     sudo /usr/local/mysql/bin/mysql -u root

For MySQL older than MySQL 5.7 use:

UPDATE mysql.user SET Password=PASSWORD('your-password') WHERE User='root';

For MySQL 5.7+ use:

USE mysql;

UPDATE mysql.user SET authentication_string=PASSWORD("your-password") WHERE User='root';

Refresh and quit:

     FLUSH PRIVILEGES;

     \q

4.  Stop the mysqld server again and restart it in normal mode.
