All Oracle Sample Schemas and all Oracle Built-in Packages in XE?

Question

Hi,
I am trying to install Oracle 10g on my home system to improve my knowledge of PL/SQL. Because I'm doing it at home, I have to solve DBA issues I'm somewhat clueless about.
I would like to install Oracle 10g Express Edition and include the built-in packages (DBMS_OUTPUT, UTL_FILE, DBMS_UTILITY, DBMS_JOB, DBMS_JAVA, DBMS_RANDOM, etc.) as well as the Oracle sample schemas (HR, OE, PM, SH, and IX). None of these, except HR, is included in the express edition.
If necessary, I'd like to be able to install these things after installing the express edition. How can I do this?
Thanks,
Mike

Hi Mike,
checking the documentation is always helpful:
http://www.oracle.com/pls/xe102/homepage
http://download-uk.oracle.com/docs/cd/B25329_01/doc/appdev.102/b25108/xedev_programs.htm#i2432
You can always do a quick search on the documentation homepage, e.g. for utl_file:
http://www.oracle.com/pls/xe102/search?remark=advanced_search&word=utl_file&format=ranked&book=&preference=
There shouldn't be a need to install any packages. They should come preinstalled already.
If not, you can find them here:
C:\oraclexe\app\oracle\product\10.2.0\server\RDBMS\ADMIN
Just be very careful before trying to install something into the data dictionary. If you are not experienced, you might mess up your database.
For example, utl_file is installed but invisible to most users, e.g. HR.
Look at this example:
SQL> conn hr/oracle1
Connect durchgef³hrt.
SQL> desc utl_file;
ERROR:
ORA-04043: Objekt "SYS"."UTL_FILE" ist nicht vorhanden
SQL> conn sys@XE as sysdba
Kennwort eingeben:
Connect durchgef³hrt.
SQL> desc utl_file;
PROCEDURE FCLOSE
Argument Name                  Typ                     In/Out Defaultwert?
FILE                           RECORD                  IN/OUT
   ID                           BINARY_INTEGER          IN/OUT
   DATATYPE                     BINARY_INTEGER          IN/OUT
   BYTE_MODE                    BOOLEAN                 IN/OUT
PROCEDURE FCLOSE_ALL
SQL> grant execute  on utl_file to HR;
Benutzerzugriff (Grant) wurde erteilt.
SQL> conn hr/oracle1
Connect durchgef³hrt.
SQL> desc utl_file;
PROCEDURE FCLOSE
Argument Name                  Typ                     In/Out Defaultwert?
FILE                           RECORD                  IN/OUT
   ID                           BINARY_INTEGER          IN/OUT
   DATATYPE                     BINARY_INTEGER          IN/OUT
   BYTE_MODE                    BOOLEAN                 IN/OUT
PROCEDURE FCLOSE_ALL
PROCEDURE FCOPY
...So, after granting execute privileges on utl_file to HR, the user HR can now access utl_file. No need to install it.
The default packages are installed in the schema SYS.
