CouchDB: Document Based Database

Did you notice that screenshot, we have something like metadata here !!!

A friend of mine (Amr Gawish) told me today about a new database engine project which I found interesting, it is called CouchDB which is a document oriented database. It is about semi-structured content as I read from Apache (for me it is about unstructured content) which manages and stores documents.

The interesting part about CouchDB is that you can use JSON and AJAX to work with database, so Google Web Toolkit will fit here too :D

The important questions, is that which future waits CouchDB? Is it practical?

Google Web Toolkit with UCM

Started development using Google Web Toolkit which in my opinion will be one of the major development tools for enterprise applications.

Let me explain from Oracle UCM point of view, in UCM services can be consumed using JSON that's by adding IsJson=1 at end of the URL, even if you created custom services you can consume them using JSON too. Now using GWT you can build your vertical solution which calls UCM services and display results and takes actions. In that way you will gain great benefits, like concentrating on user interface, build easy to use application, and lightweight too which will attract customers.

I recommend you to take a look and consider it seriously as another point of view for development.

Active Directory Notes

I was working on integration on Active Directory with Oracle UCM 11g and I have the following notes that may be helpful:

- Change DefaultAuthenticator's Control Flag from REQUIRED to SUFFICIENT

- We are not using Oracle UCM LDAP Providers for integration with Active Directory anymore

- Users mapping between Oracle UCM and Weblogic embedded LDAP is done using JpsUserProvider provider

- In Oracle UCM 11g, you can give default roles and accounts for authenticated users, to do that from Oracle UCM Providers page edit a provider called JpsUserProvider and in Default Network Roles field add the default roles separated with commas, for default accounts use Default Network Accounts field

- Any weblogic ldap user assigned to administrators group, he will have Oracle UCM admin role

Starting Weblogic Admin Server and Node Manager as background service

The following steps explains how to start Weblogic Node Manager and Admin Server automatically with Linux OS (Redhat in my case):

- Create boot.properties file under

/user_projects/domains/my_domain/servers/AdminServer/security

- Add to the file the following entries

username=weblogic
password=welcome1

- Create a file called wlsndm under

/etc/init.d

- Add to the file the following

#!/bin/bash
#
# wlsndm startup script for node manager
#
# chkconfig: - 74 15
# description: weblogic
# processname: WLSNDM

# Source function library
. /etc/rc.d/init.d/functions

start() {
echo -n $"Starting $prog: "
nohup su - oracle -c /wlserver_10.3/server/bin/startNodeManager.sh > /wlserver_10.3/server/bin/wlsnd.log &
echo "OK"
}

case "$1" in
start)
start
;;
*)
echo $"Usage: $prog {start}"
exit 1
esac

exit 1

- Create a file called wlsadmin under

/etc/init.d

- Add to the file the following

#!/bin/bash
#
# wlsadmin startup script for node manager
#
# chkconfig: - 75 15
# description: weblogic
# processname: WLSADMIN

# Source function library
. /etc/rc.d/init.d/functions

start() {
echo -n $"Starting $prog: "
nohup su - oracle -c /user_projects/domains/my_domain/bin/startWebLogic.sh > /user_projects/domains/my_domain/servers/AdminServer/logs/wlsa.log &
echo "OK"
}

case "$1" in
start)
start
;;
*)
echo $"Usage: $prog {start}"
exit 1
esac

exit 1

- Create the following symbolic links under /etc/rc5.d/

ln -s /etc/init.d/wlsndm S74NodeManager
ln -s /etc/init.d/wlsadmin S75Weblogic

- then Create background services

chkconfig --add wlsadmin
chkconfig --add wlsndm

- Activate the created background services

chkconfig wlsadmin on
chkconfig wlsndm on

Now we have finished creation of background service, and you can start UCM or any other Managed Server from Admin Server Console. Using the same approach you can start UCM automatically.

Using UCM11g Logout With Site Studio

As most of us remember in Oracle UCM 10g, logout was not there by default. In UCM 11g Oracle has added logout to be there by default.

Also it is noticed there is new Service (LOGOUT) added to UCM 11g for logout and that service make use of redirect template.

What if you want to secure parts of a website designed by Site Studio using Oracle UCM security (may be it is intranet and you want to add security to HR section). Definitely UCM security will be used on a section and/or a layout, however you will need to add logout, and you want logout to redirect you to some page like home page or login screen.

To do that create your logout link like below

<a style="text-decoration:none " href='/cs/idcplg?IdcService=LOGOUT&RedirectUrl=%2Fmywebsite%2Findex.htm'>Logout</a>

Removing Subscribe and Unsubscribe from DOC_INFO template

Someone called Anonymous :D has commented from days on one of my posts asking me how to remove subscribe and unsubscribe menu items.

To do that will need to modify a resource include called docinfo_menus_setup.

Simply follow these steps if you are not familiar with Oracle UCM ComponentsWizard utility
- Open ComponentWizard utility
- Add new component, choose a name you want
- Add new Resource of type HTML Include/String 
- Inside in the new resource file, select an existing resource include called docinfo_menus_setup
- Do your modifications on the code inside the chosen include, enable the component, and restart the server.

I hope it is helpful for you Anonymous
