The part I liked most is the ending “My Wish Is…”

For each object that Hibernate loads, it needs to do one or more extra SQL queries to load associated objects. (Potentially as many as Kn + 1, where n is the number of objects returned).

Example:

• Simplified hibernate mapping file
  

  <class name=”Department”>
  

  …
  

  <many-to-one name=”employee”…/>
  

  …
  

  </class>
  

• Simple HQL Query
  

  from Department dept where dept.location like :LOCATION
  

• The generated SQL statements:
  

1. At least the initial select.
   

   select dept_id, deplt_name, dept_location…from department…
   

2. Then a sequence of selects from the associated table. (n sql select statements)
   

   Select …from employee…
   

   Select …from employee…
   

   Select …from employee…
   

   …
   

   If Sale table returns 100 rows, you will see 100 select statements extra more than the main select statement.
   

The solution (1):

The association objects must be loaded in the initial query and just when you need them. This can be done by adding ‘left join fetch’ for example and switching the lazy loading on.

from Department dept left join fetch dept.employee

where dept.location like :LOCATION

This will generate just one sql select statement.

The solution (2): When there are a lot of association tables

You don’t want to end up with query like this:

from Department dept

left join fetch dept.employee

left join fetch dept.manager

left join fetch dept.building

left join fetch dept.level

left join fetch dept.city

…etc

The approach involves determining exactly which columns you really need, and instantiating data-transfer objects containing exactly those columns.

Select new Department (dept.id, dept.employee.name, dept.manager.name, …) from Department dept

…

This technique is fast and efficient, and avoids the overheads of handling associated objects and of loading large numbers of persistent objects into the Hibernate session cache. The only downside is the need to create a dedicated data-transfer class for each query, and an overloaded constructor.

1. Install IIS 7
2. Install Application Request Routing http://learn.iis.net/page.aspx/482/install-application-request-routing/
3. Open IIS Manager

Press Add and then Finish

Press Yes

Try to request for a page on MOSS server from the web server.

http://WEB_SERVER/Pages/Memos.aspx

This will be forward the request to MOSS server

http://WEB_SERVER/Pages/Memos.aspx to http://MOSS:PORT/Pages/Memos.aspx

The client will not notice this!

For IIS6 (To send request from one IIS6 to another one an delegate user login information)

We have managed successfully to configure IIS 6 as reverse proxy and delegate authentication to the second IIS 6 using ISAPI_Rewrite version 2. Previously, we were using the latest version of ISAPI_Rewrite 3.0 , the documentation of this version mentions that is working with basic authentication , but it didn’t work with us. Basic authentication is supported with version 2, Now we have managed  successfully to delegate authentication to from one IIS to other one with extra configuration on both IIS servers &  ISAPI_Rewrite. All users must be a domain users and visible by both IIS servers to get the user be authenticated.

This is the Exception we were getting in the test server; this error will prevent any eservices actions to be performed. In our eservices actions, we are using PUBLIC user account to perform some LDAP operations. If anything wrong happen with this account the eservices action will fail.

PASSWORD POLICY ERROR: 9000: GSL_PWDEXPIRED_EXCP

The default value for Password Expiry Time is set to 5184000 that is, 60 days. After 60 days from the installation date, the passwords for the Oracle directory server (and any other assigned passwords) automatically expire. Soon after password expiration, this repeated trying causes the connector to exceed the max grace logins exceeded, and the account to become locked.

Cause: Beginning with Release 9.0.4, the pwdmaxage attributes of the password policies are defaulted to time value of 60 days.

Action: Do the following:

1. Use oidpasswd utility to unlock the orcladmin account (If this account is locked):
   

   You have to set ORACLE_HOME
   

   
   

2. Launch the Oracle Directory Manager (must be a release 10g client), login using orcladmin account, and write the IP address for OID server
   

   
   

3. Navigate to Password Policy Management.
   

   
   

   You will see two entries: cn=PwdPolicyEntry and the password policy for out realm, Password Policy for Realm dc=company,dc=com.
   

   Edit each of these, changing the pwdmaxage attribute to an appropriate value:
   

• 5184000 = 60 days (default)
  
• 7776000 = 90 days
  
• 10368000 = 120 days
  
• 15552000 = 180 days
  
• 31536000 = 1 year
  
• 0 = Infinity
  

Subversion is a centralized system for sharing information. At its core is a repository, which is a central store of data.

Install Subversion

You have to install two things:

1. Subversion Server (Repository)
2. Subversion Client (Used to connect to the repository)

Subversion Server Installation and configuration:

Download the latest SVN server from http://subversion.tigris.org/project_packages.html

I have downloaded Subversion Server under Windows

http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91

Install SVN server.

After complete the installation, you have to set some environment variables:

Subversion binaries to the path environment variable for the machine.

SVN_EDITOR, set to the text editor of your choice. I used c:\windows\notepad.exe

Create a Repository

Create repository folders in your hard drive, I have created

c:\svn_repository\

Open command prompt and type:

svnadmin create "c:\svn_repository"

Now, you have a repository and you can start using it.

But first we have to configure SVN server, to let any one in your 

network to use this repository.

Navigate to the folder we just created. Within that folder, uncomment the

 following lines in the c:/svn_repository/conf/svnserve.conf file:

anon-access = read

Any user who is not authenticated user can read

auth-access = write

Any authenticated user can write

password-db = passwd

The user names and passwords are in the default file 

c:/svn_repository/conf/passwdc:/svn_repository/conf/passwd
					

sami.alsayyed = sami123

User name: sami.alsayyed

Password: sami123

Start SVN server by executing this command:

svnserve --daemon --root "C:\svn_repository"

Keep this screen and open another command prompt window.

Install SVN as windows service

To start SVN server as windows service, just execute this command

sc create svn binpath= "C:\Program Files\Subversion\bin\svnserve.exe --service -r 

C:\svn_repository" displayname= "Subversion Server" depend= Tcpip start= auto

After that you should see the new service "Subversion Server"

Now any one in your network can see your repository and use it.

Test the new service by listing all the files in the repository:

Create a new project in the repository by executing this command:

svn mkdir svn://localhost/myproject

At this point, Notepad should launch:

Enter any comment you want at the top of the file, then save and exit.

You'll now be prompted for credentials. In my case I was prompted for the administrator credentials as well:

Authentication realm:  0f1a8b11-d50b-344d-9dc7-0d9ba12e22df

Password for 'Administrator': *********

Authentication realm:  0f1a8b11-d50b-344d-9dc7-0d9ba12e22df

Username: sami.alsayyed

Password for 'sami.alsayyed': ************

Committed revision 1.
				

Congratulations! You just checked a change into Subversion!

Install SVN Client "TortoiseSVN"
				

Download the latest TortoiseSVN from here: http://tortoisesvn.net/downloads				

Run the TortoiseSVN installer. It will tell you to restart, but you don't need to.

You have to install this software in all clients, to let them access your 

SVN repository and use it.Assuming you are some of the clients, after 

installation complete you have to check out the project in the repository.

Create a project folder somewhere on your hard drive. 

Right click in that folder and select "SVN Checkout..."

svn://localhost/
is the URL for the repository, if you are setting in a different 

machine you have to write the computer name or IP address

Click ok. After that you will see this window:

Click ok, you have successfully checked out the projects inside the 

repository first project we have added lately to the repository.

Try to add some document to this folder "myproject"

Create a new file in that directory. Right click the file and select "TortoiseSVN, Add"

Click ok.

Click ok

The file hasn't actually been checked in yet. 

Subversion batches any changes and commits them as one atomic operation.

To send all your changes to the server, right click and select "SVN Commit":

Type you comment and press ok

You have to write your user name and password to commit this file, you should be authenticated user.	

And we're done! You now have a networked Subversion server and client set up on your machine. 

Note that the default port for svnserve is 3690.

Some quick commands
					

svnadmin create c:/svn_repository

svn import C:\from_file svn://localhost/

svnadmin dump c:/svn_repository > dumpfile

svnadmin load c:/svn_repository < dumpfile

svnadmin hotcopy c:/svn_repository c:/backup_svn_repository

svnserve --daemon --root "C:\svn_repository"

sc create svn binpath= "C:\Program Files\Subversion\bin\svnserve.exe

 --service -r C:\svn_repository" displayname= "Subversion Server" 

depend= Tcpip start= auto

svn mkdir svn://localhost/myproject

svn log svn://localhost/

svn checkout svn://localhost/ c:\myproj

svn add a-file-I-added.txt

with the status

svn st

svn ci -m "Put a comment here, 

or an editor opens to get one."

svn rm unwanted-file.txt

svn mv badname.txt goodname.txt

svn up

Assumption: Install PDA on development environment server 172.19.69.184

Overview

The OracleAS Portal Diagnostics Assistant is a tool for gathering information when troubleshooting OracleAS Portal issues. The OracleAS PDA is intended for use by Oracle Portal installers and users who come across issues after installing Portal. The issues can vary from accessing Portal to users getting errors at different levels within Portal. The PDA user can self diagnose the issue by reviewing the results from the PDA output or upload the files to Oracle Support via metalink.

Installation

$ORACLE_HOME environment variable should be set to Oracle Application Server Portal Middle Tire Oracle home directory

Download the scripts from here:

http://www.oracle.com/technology/products/ias/portal/files/pdav4.zip

Put pdav4.zip that you have downloaded on the server and extract it there.

Login to the server using ftp tool like, WinSCP

Create a new folder

Open the folder

Put pdav4.zip file there

Now, we have to extract this file

Login to the server using PuTTY and go the folder you have created

Unzip pdav4.zip

Execute this command to install PDA

pda.csh -schema portal_schema -password portal_password -connect portal_connect -ssoSchema orasso_schema -ssoPassword orasso_password -ssoConnect orasso_connect

portal_schema: Portal schema name

portal_password: This is the database password, not the same password you
use it to login Portal Builder

orasso_schema: Single Sign On schema name

orasso_password: Single Sign On database password

To get these passwords there are two approaches:

FIRST

- Open the Oracle Directory manager and login: (This requires a server access)

- username=orcadmin

- password=(during installation of AS this password was asked)

- server= Development server name or IP

- port=probably 389 or 4032

- The Oracle directory manager will open; in there you will have to follow this path:

Entry Management à OraclContext à Products à IAS à cn=IAS Infrastructure database à orclReferenceName=<DBName> à PORTAL/ORASSO

You will find there orclpasswordattribute, this is the database password for each one.

SECOND

Execute these commands

ldapsearch -h Server_name -p 389 -D cn=orcladmin -w pswd -b “cn=IAS Infrastructure Databases,cn=IAS,cn=Products,cn=OracleContext” -s sub “orclResourceName=portal” orclpasswordattribute

ldapsearch -h Server_name -p 389 -D cn=orcladmin -w pswd -b “cn=IAS Infrastructure Databases,cn=IAS,cn=Products,cn=OracleContext” -s sub “orclResourceName=orasso” orclpasswordattribute

This is the command I have executed

./pda.csh -schema portal -password XXXXXX -connect 172.19.69.155:1521:XXX -ssoSchema orasso -ssoPassword XXXXXX -ssoConnect 172.19.69.155:1521:XXX

If you got Permissions Denied error, just give permissions to the current user by executing this command in the PDA_INSTALLATION folder

Chmod 777 *.*

It will take a few minutes, but you should see this message at the end:

Now, PDA reports have been generated.

Open the server using FTP client like WinSCP

Open the folder that contains our PDA files

You will notice two new things:

PDA071122103016.zip file

071122103016 Folder

To view the reports you have to open pda.htm using your browser

The two files are the same, one if you like to open pda.htm remotely from the server and the other one PDA071122103016.zip if you like to open pda.htm from your machine

The directory names have a timestamp format, for example, 030623132344 which means: {year}{month}{day}{hour}{minutes}{seconds} so each time it will be changed

I will try the second option.

Copy the file PDA071122103016.zip and paste it in your desktop for example

Extract PDA071122103016.zip any where

Open the extracted folder, and open pda.htm

Narrowing a Search (if you have too many results) and

Expanding a Search (if you don’t get enough)

Tip 1: Case Doesn’t Matter

Google doesn’t care whether search terms are entered in upper case or lower case.

Tip 2: Searching for Words and Phrases

Suppose, for example, you are looking for pages related to search engine optimization (SEO). Entering search engine optimization as three separate keywords will return something like 35 million results—which would take you a while to check through! Some experimentation can make this a little more manageable, as shown below:

• search engine optimization: 34,700,000 results
  
• “search engine optimization”: 23,000,000 results
  
• “search engine optimization” tips: 1,760,000 results
  
• “search engine optimization tips”: 196,000 results
  

Tip 3: Including and Excluding Keywords

word1 +word2 will force Google to include word2 in the search

word1 –word2 will force Google to exclude word2 in the search

Example: virus –computer would return only Web pages about biological viruses not computer viruses.

Tip 4: Logically Combining Searches

Use or to search for multiple terms

word1 OR word2 finds pages that include either word

Use ~ to search for synonyms of a term

~word1 finds pages that include word1 or its synonyms

Use * as a “wildcard” with your search terms

“word1 * word2″ finds pages that includes this phrase where * can be any one word

Tip 5: Searching Titles, Body Text and URLs

intitle:keyword: search for a single keyword (or quoted expression) in the title

allintitle:keyword1 keyword2 …: search for a list of keywords (and/or quoted expressions) in the title

inurl:keyword: search for a single keyword (or quoted expression) in the URL

allinurl:keyword1 keyword2 …: search for a list of keywords (and/or quoted expressions) in the URL

Tip 6: Searching a Website or an Area of the Web

Add site: to search only specific sites or types of sites:

word1 site:psut.edu.jo will search only on the psut site.

word1 site:.edu will search only education sites

word1 site:.gov will search only government sites

word1 site:.org will search only non-profit sites (mostly), museums, libraries, etc.

word1 site:.edu.jo will search only educational sites in Jordan

Add filetype: to search for documents other than Web pages

Filetype:pdf will return only files in the PDF format (good for finding handouts and worksheets). You can also use this to search for PowerPoint (.ppt) MS Word (.doc) Flash ( .swf) and many other kinds of files.

Tip 7: Searching for other kinds of information

Definitions (define)

This search will return definitions listed in online dictionaries. In addition to standard definitions, this also returns jargon definitions from specific disciplines such as sports, science, geek, etc. (e.g. try “pickle”).

Contact information

When you enter a person or business name with a location (city, state) any contact information listed in an online white page will appear in the results.

Phone number

(phonebook: rphonebook: bphonebook:) when you enter a phone number, any name or address listed in an online white page will appear in the results

Address

Entering a full address will return a link to a map to that location.

Calculations

Entering mathematical expressions will return the result simple math (+ – * /) exponentials (^) percentage (% of) even advanced math (see the Google site for details)
