1.5 Unlocking HR Schema -*
1) After Installing Oracle XE, you can access ‘system’ schema but not ‘hr’ schema. ‘hr’ schema
comes along with Oracle XE database, but locked. To unlock ‘hr’ schema from database to
grant permission to the users to utilize this schema, follow below steps.
a) Click Start > expand Oracle Database 11g Express Edition > select Run SQL
Command Line.
Run SQL Command Line editor opens.
b) In the editor, enter connect; command
c) Enter the user name and password for the ‘system’
Enter user-name: system (case insensitive)
Enter password: sysadmin (case sensitive)
d) Enter the following command to unlock the ‘hr’ Schema
SQL> ALTER USER HR IDENTIFIED by hr ACCOUNT UNLOCK;
e) Exit from the editor by giving command “exit” or by closing directly.
f) Now login with ‘hr’ user and password
User Name: hr (case insensitive)
Password: hr (case sensitive)
g) Now you can use all tables specified in tutorial.
h) Unlocking the HR Schema
OR
2) Alternatively, you can also unlock ‘hr’ Schema from JDeveloper as follows
a) Once you are connected as system, expand the tree in the connection panel
as Connections->SYSTEM->Other Users
b) Right-click on HR to access the Edit User dialog.

10/454
c) Within the dialog, simply uncheck the box entitled Account is Locked and
click Apply.
d) After completing this process, you should now have a fully functional Oracle XE
database with the example HR schema unlocked.

1.7 Working with JDev IDE Configuration Files -o
1) The locations from where you can start JDeveloper apart from the shortcuts are:
a) MW_HOMEjdeveloperjdeveloper.exe
b) MW_HOMEjdeveloperjdevbinjdevw.exe
c) MW_HOMEjdeveloperjdevbinjdev.exe
The first two options have the same purpose. The last option will open along with a console
for diagnostic purposes. Example of MW_HOME is C:OracleMiddleware122100.
2) An alternate way for this is to set the JDEV_USER_DIR environment variable that points
to the user's current working directory.
JDEV_USER_HOME and JDEV_USER_DIR are the variables that are listed in the
MW_HOMEjdeveloperjdevbinjdev.boot file. JDeveloper will look up these variables on
startup to set the user's directory. For example:
set JDEV_USER_HOME=C:Users<<User>>AppDataRoamingJDeveloper
set JDEV_USER_DIR=D:<<User>>BATJDev122100mywork
3) Location of IDE configuration files:
a) MW_HOMEjdeveloperidebinide.conf
b) MW_HOMEjdeveloperjdevbinjdev.conf
4) Location of IDE boot files:
a) MW_HOMEjdeveloperidebinide.boot
b) MW_HOMEjdeveloperjdevbinjdev.boot

1.10 Grouping of Hands-on Lab Practices -*
1) There is no Lab 01, Lab 10 and Lab 21.
2) Lab 02, Lab 16, Lab 17 and Lab 25 are independent Lab practices and are not dependent
on any other Lab.
3) Lab 02, Lab 04, Lab 11, Lab 16, Lab 17, Lab 25 are new starter Labs.
4) Lab 04 continues to Lab 09 and has practices on ADF BC. Later Lab 09 merges with Lab 22
into one Application.
5) Lab 11 continues to Lab 24 (excluding Lab 16, Lab 17). Later Lab 15 adds Lab 09 as ADF
Model Library.
6) Lab 20, Lab 24 and Lab 28 are full applications like real-time project.
7) To get a feel of lab objectives and practices, run Lab 20 or Lab 22.

5.4 Examining Attribute Settings -*
Examine, explore, understand and familiarize with all settings of an Attribute.
1) Property Set: Select a named property set to apply to this attribute. A property set is a
version of an existing domain that is XML-only (no Java) and does not enforce a data type.
2) Effective Date: Specify effective date properties for the attribute. These options are
available only if the attribute type is Date.
3) Start Date: Select to indicate that this attribute is the start attribute of an effective dated
entity object.
4) End Date: Select to indicate that this attribute is the end attribute of an effective dated
entity object.
5) Sequence Flag: Select to indicate that this attribute stores a flag indicating the most recent
change in the sequence for an effective dated entity object.
6) Sequence: Select to indicate that this attribute stores a sequence of changes for an
effective dated entity object.
7) Updatable: You can enable the attribute to Always or Never be updatable or enable it to
be updated only before the entity is first posted (While New).

70/454
8) Queryable: Specify that this attribute can occur in the WHERE clause of a view object
(selected by default except for LOBs).
9) Precision Rule: Specifies that a validator is applied by the framework at runtime to enforce
the maximum precision and scale of the data type. If selected, the validation is performed
by the entity. If not selected, the validation is not performed by the entity and may result
in invalid precision/scale errors from the database when the transaction is committed.
10) Refresh on Insert/ Update: Specify whether to retrieve the value from the database
after an insert or update.
11) Change Indicator: Select this option if the column is a change indicator, such as a
timestamp, to be used to indicate that a row has been changed by another transaction. (If
no columns are specified as change indicators, ADF BC does a column-by-column
comparison.)
12) Effective Date: The attribute is either the start or end date of a date range for which the
entity row is effective (used for a point of time snapshot to answer such questions as what
an employee’s salary was on January 30, 2004.)
13) History Column: Select to use this column to log changes to the database. You can log
changes only if you have implemented Java Authentication and Authorization Service (JAAS)
authentication, the selected attribute is persistent, you have not selected Primary Key,
Mandatory, or Discriminator, and the attribute is Char, Character, String, Date, Timestamp,
or Number. After you have selected History Column, you can select the history column type
(created on or modified on for a Date or Timestamp attribute, created by or modified by for
a Char, Character, or Stringattribute, or version number for a Number attribute).
14) Generate Unique Constraint: Select to generate a UNIQUE constraint for this attribute.
It is often useful to define an attribute so that its values must be unique. For example, you
might want to enforce that every customer has a unique email address.
15) Sequence Name: Enter the name of the database sequence. The sequence name shown
on the Sequence tab is applicable only at design time when you use the Create Database
Tables feature. The sequence indicated here will be created along with the table on which
the entity object is based. This field is not available for all attribute types.
16) Start At: Enter an integer value you want the sequence to start at, the default value is 1.
This field is not available for all attribute types.
