How to call a shell script from another shell script

Note: Make sure to add #!/bin/bash to the first line of the script and make it executable through chmod 700 <path to script>.

1. <path to script> or /bin/bash <path to script> or <scriptname> (add script to $PATH environment variable and call as normal command)
   - child script is executed in a new shell, changes in child script does not affect parent script
   - can be executed asynchronously through background command
2. <path to script> &
   - same as no. 1 but executes child script on background
3. source <path to script> or . <path to script>
   - child script is executed in a current shell
   - context is same as parent script (vars and functions of child script becomes visible on parent script)
   - exit call in child script will also exit the parent script
4. exec <path to script>
   - terminates the current shell and executes on a new shell

How to create Bash Script on Mac

1. Create the bash script file.
   Sample: File myscript.sh

   #!/bin/bash     #”hash-bang" or “she-bang" indicating that this script is to be interpreted and run by the bash shell
   echo hello world     #prints “hello world”
   

2. Change the file permission to make it an executable. Open the terminal, navigate to the location of the file and type the following command:
   

   chmod 700 myscript.sh 

   See this link for more info on chmod: http://www.thinkplexx.com/learn/article/unix/command/chmod-permissions-flags-explained-600-0600-700-777-100-etc
3. Run the script. Type the following in the terminal:
   

   ./myscript.sh

Key Terms in Strategic Management

Most of these terms are used interchangeably and may mean different from one person to another. Based on various sources I read, here's what I think they mean:

Mission - enduring purpose/duty, most important aim

Vision - desired future state supporting mission

Goals / Objectives - what the organization intends to do, an end-game

Strategy
- a chosen path, direction or plan of action, to achieve goal
- involves all or most of the resources within organization
- usually long-term
- usually timeless
- what to do?

Tactics
- way to a achieve sub-goals or implement strategy, tools
- performed by a subset or a specific ___ in  an organization
- shorter to mid term
- may vary depending on some factors like time, environment, etc.
- how to do?

Strategies should consider the tactics and tactical solutions should be aligned with strategies.

Some examples from Jan Zlotnick:

Goal: Be the market share leader in terms of sales in the mid-market in our industry.
Strategy: Remarkable Customer Service
Tactics: Offer lower cost solutions than enterprise competitors without sacrificing white-glove service for first 3 years of customer contracts.

Goal: Become a social utility that earth uses on an daily basis.
Strategy: Love Your Neighbor
Tactics: Offer a free global communication toolset that enables disparate personal interactions with your friends to monitor, share, and interact with.

Execution - implementation

Outline: Talent is never Enough

by John C. Maxwell

When is talent alone enough?

- Talent is never enough. If talent were enough, then the most effective and influential people would always be the most talented ones.

- Intelligence, imagination, and knowledge are essential resources, but only effectiveness converts them into results. - Peter Drucker, the father of modern management

- Some tasks are not improved by adding more people.

- More isn't always better, and some things are best done by an individual.

- But there are many tasks that call for talent more than numbers. Like high jumping, they require the extraordinary talent of one person, not the mediocre talent of many.

Putting talent into perspective

1. We should marvel at their giftedness.
2. We should recognize their contribution to society?
3. We should separate what they can do from who they are.

- Talent gives you a head start on others but to keep on being a success, you should keep working on that talent.

Do you have what it takes?

1. Everyone has talent. Find your talent.

2. Develop the talent you have, not the one you want.

3. Anyone can make choices that will add value to talent.
- Destiny is not a matter of chance, it is a matter of choice. - William Jennings Bryan

DB2 CHAR VS VARCHAR

CHAR

VARCHAR disadvantages:
- uses 2 extra bytes to store the length
-  needs a little extra effort when storing and manipulating length of VARCHAR -> may affect efficiency


General Rule:

• Use CHAR if average length of field is more than 6 bytes to save space
• if average length of field is less than 6 bytes, there will be no storage savings for using char
• Use varchar for columns with more that 30 characters (can be shorter for others)

Creating a SOAP Web Service

1. Create the Java class with methods you want to be converted as web service
2. Add a WebService annotation to the class
3. Add WebMethod annotation to the web service method. This is optional. All public methods of the web service class are automatically considered a web service method.

Example:

@WebService
public class BookStore{
@WebMethod
 public List<String> getBookNames() {
 }
}

This will create a web service class called BookStoreService.

Consuming a Web Service

What you need:
- wsdl source

1. Use wsimport tool from java se. In command line enter:
wsimport -keep -s , e.g. wsimport -keep -s src
-keep - keep generated files (.java files)

2. Import the the java files in your project and use them as stubs to call the webservice method(s). The name of the stub you can use can be found in the wsdl:service tag of the wsdl.
Ex.
 name="CurrencyConvertor">

CurrencyConvertor cc = new CurrencyConvertor();
CurrencyConvertorSoap ccs = cc.getCurrencyConvertorSoap();
