Artifactory by Jfrog http://www.jfrog.org/products.php

This will walk-through setting up a corporate Maven2 setup with a sample project including SVN integration and exporting the project into the corporate repository and re-using it in another project. More details will be added iteratively.

Setup your corp maven repos

Download, install and config artifactory.

Run artifactory.

Deploy the artifactory settings.xml to your developers (they can put it in maven folder or ${user.home}/.m2/settings.xml)

All maven requests will now be proxied thru artifactory and artifactory will cache the libs.

Create a new project

mvn archetype:generate -DgroupId=mygroup -DartifactId=MyLib -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

in the artfiactory tree browser, browse to a local snapshot container and copy the distribution management xml into your project pom.xml

Modify your user settings.xml to add the username/password for the repository so you can export.

Add a new java class such as MyCalc:

package mygroup;

public
class MyCalc {

    public
static
int square(int num) {

        return num * num;

    }

}

Export the project:

$ mvn deploy

View the artifact in artifactory console.

Use the new class

mvn archetype:generate -DgroupId=mygroup -DartifactId=MyProject2 -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

add to the pom file a dependency on the new artifact:

<dependency>

    <groupId>mygroup</groupId>

    <artifactId>MyLib</artifactId>

    <version>1.0-SNAPSHOT</version>

</dependency>

Create the App class for this project:

import
mygroup.MyCalc;

public
class App {

    public
static
void main(final String[] args) {

        System.out.println(MyCalc.square(6));

    }

}

Run it!

Add JavaDoc distribution

Wire the SharedLib to SVN

* Download IIS 6.0 Resource Kit Tools

* Install the resource kit (requires Windows Server 2003, Windows XP)

* From the Windows Start Menu, go to the “\Programs\IIS Resources\SelfSSL” folder and select “SelfSSL”.

* Instructions will be listed in a command prompt. Type “selfssl” to run the program.

* Type “y” to confirm overriding/installing the certificate on the given site.

* Test that it worked by visiting https://localhost

sudo mount -t ntfs-3g /dev/sd[a|b|...][0|1|...] /media/mywindrive -o force

Fstab for mounting a windows share:

/dev/sd[a|b|...][0|1|...] /media/mywindrive ntfs-3g quiet,defaults,rw 0 0

Unmount:

sudo umount /media/mywindrive

Fix vmware bridging issue

http://communities.vmware.com/thread/207661

(stop and start vmware services)

sudo /etc/init.d/vmware stop

sudo /etc/init.d/vmware start

Backup files with update feature:

cp –verbose -r -u / /

i.e. cp –verbose -r -u data/ /media/backup-vol/ (this will create dir data under the /media/backup-vol/)

cp –verbose -r -u user/ /media/SEAGATE_EXT/backups/

VMWare virtual disk mounting operations:

Show partitions of a vdisk:

sudo vmware-mount -p XYZ.vmdk

Mount:

sudo vmware-mount /media/myvmdk-vol (target path must exist first)

Unmount cleanly:

sudo vmware-mount -d /media/myvmdk-vol

Who is accessing a specific file or filesys?

fuser -v -m -u path

Graphical conf editor

sudo gconf-editor

Disable/Enable Automount (didn’t seem to work)

gconftool-2 –set /apps/nautilus/preferences/media_automount false|true –type bool

Get Automount status (didn’t seem to work)

gconftool-2 –get /apps/nautilus/preferences/media_automount

Install Java

sudo apt-get install sun-java6-jdk    

Browse from here (if nautilus is your navigator of choice):

nautilus $PWD

Run a VM from the command-line:

sudo vmrun start &

Create an ISO from a device:

dd if=/dev/XXXX of=YYYY.iso

Convert a virtual disk example: info

sudo vmware-vdiskmanager -s 30GB -r -t 0 path &

Shrink a virtual disk (doesn’t seem to work):

Use the vmtools inside the guest machine?

xcopy src dst /c /d[:mm-dd-yyyy] /s

If no date is specified for /d param, all new or updated files are copied.

Coming soon, powershell and Cygwin versions

A simple example

In this example, it is assumed that a company consists of different departments (with each having an entry in the departments table). An employee belongs to exactly on department. A department can have secrets that go into the department_secrets table.

create table department (

dep_id int primary key,

name varchar2(30)

);

create table employee (

dep_id references department,

name varchar2(30)

);

create table department_secrets (

dep_id references department,

secret varchar2(30)

);

Filling in some truly confidential secrets:

insert into department values (1, ‘Research and Development’);

insert into department values (2, ‘Sales’ );

insert into department values (3, ‘Human Resources’ );

insert into employee values (2, ‘Peter’);

insert into employee values (3, ‘Julia’);

insert into employee values (3, ‘Sandy’);

insert into employee values (1, ‘Frank’);

insert into employee values (2, ‘Eric’ );

insert into employee values (1, ‘Joel’ );

insert into department_secrets values (1, ‘R+D Secret #1′ );

insert into department_secrets values (1, ‘R+D Secret #2′ );

insert into department_secrets values (2, ‘Sales Secret #1′);

insert into department_secrets values (2, ‘Sales Secret #2′);

insert into department_secrets values (3, ‘HR Secret #1′ );

insert into department_secrets values (3, ‘HR Secret #2′ );

For any employee, it must be possible to see all secrets of his department, but no secret of another department.

In order to make that happen with Oracle, we need to create a package, a trigger, and set a policy.

First, the package is created.

create or replace package pck_vpd

as

p_dep_id department.dep_id%type;

procedure set_dep_id(v_dep_id department.dep_id%type);

function predicate (obj_schema varchar2, obj_name varchar2) return varchar2;

end pck_vpd;

/

create or replace package body pck_vpd as

procedure set_dep_id(v_dep_id department.dep_id%type) is

begin

p_dep_id := v_dep_id;

end set_dep_id;

function predicate (obj_schema varchar2, obj_name varchar2) return varchar2 is

begin

return ‘dep_id = ‘ || p_dep_id;

end predicate;

end pck_vpd;

/

Then the trigger is defined. This trigger fires whenever someone log on to the database. It finds the user’s departement id (dep_id) and calls set_dep_id in the package.

create or replace trigger trg_vpd

after logon on database

declare

v_dep_id department.dep_id%type;

begin

select dep_id into v_dep_id

from employee where upper(name) = user;

pck_vpd.set_dep_id(v_dep_id);

end;

/

Finally, the policy is defined. The policy states which procedure is used to add a where clause part to the where clause if someone executes a select statement.

begin

dbms_rls.add_policy (

user,

‘department_secrets’,

‘choosable policy name’,

user,

‘pck_vpd.predicate’,

‘select,update,delete’);

end;

/

To test the setup, some users are created.

create user frank identified by frank default tablespace users temporary tablespace temp;

create user peter identified by peter default tablespace users temporary tablespace temp;

create user julia identified by julia default tablespace users temporary tablespace temp;

The necessary privileges are granted.

grant all on department_secrets to frank;

grant all on department_secrets to peter;

grant all on department_secrets to julia;

grant create session to frank;

grant create session to peter;

grant create session to julia;

A public synonym is created.

create public synonym department_secrets for department_secrets;

Frank (belonging to R+D) executes a query….

connect frank/frank;

select * from department_secrets;

DEP_ID SECRET

———- ——————————

1 R+D Secret #1

1 R+D Secret #2

Peter (belonging to Sales) executes a query….

connect peter/peter;

select * from department_secrets;

DEP_ID SECRET

———- ——————————

2 Sales Secret #1

2 Sales Secret #2
