When I try the following http debug parameters in opmn for my oc4j instance I get no logs after restarting instance:

I am trying to increase the Xmx value to 1500M on JDev. However when I do so, I get the "Error occurred during initialization of VM Could not reserve enough space for object heap" error. I am on Windows XP and have 4GB of RAM. And have plenty of available RAM.

When running a select statement in sqlplus on a nested tables we get the results returned. However the same can not be said when running the same statement through JDBC. He is an example of returning values from a nested table with JDBC.

1. Here's how the sql script looks like to create the type and tables.

drop table person;
drop type nested_addresses;
drop type address;

create or replace type address as object(
 street varchar2(50),
 city varchar2(20),
 postcode varchar2(8),
 state varchar(8))
/

create or replace type nested_addresses as table of address
/

create table person (
 firstname varchar(20),
 lastname varchar(20),
 address_list nested_addresses
 ) nested table address_list store as person_addresses
/

insert into person values ('Fred','Flinstone', nested_addresses(address('345 Cave Stone Road', 'Bedrock', 'BR345','BR'),address('1313 Cobblestone Way', 'Bedville', 'BV1313','BV')))

Note for myself to create a simple custom ADF login page with jspx.

Create a new workspace by following the example shown here:

http://www.oracle.com/technology/products/jdev/11/cuecards111/adf_set_29/ccset29_ALL.html

Once completing this, then go through the follow link http://download.oracle.com/docs/cd/E15523_01/web.1111/b31974/adding_security.htm#BABDEICH to create the custom jspx page and backing bean to login into the application.

The finished login will look something like this.



Download completed workspace from here.

I haven't had the chance to write something for a while now. I was recently working on new feature with oracle advanced security data encryption and integrity using a JDBC connection pool. So I'll write my steps up of how I went about configuring this in OAS 10g.

This setup allows for data encryption and integrity without the overhead of SSL.

I used the following products to configure the steps detailed here:

* Oracle Application Server 10.1.3.2.0
* JDev 10.1.3.4.0
* JDBC 11.2.0.1.0
* Oracle Database 11.2

I am referencing these documentation for further details:

Oracle® Database Advanced Security Administrator's Guide 11g Release 2 (11.2)
Configuring Network Data Encryption and Integrity for Oracle Servers and Clients
http://download.oracle.com/docs/cd/E11882_01/network.112/e10746/asoconfg.htm#insertedID0

Oracle® Database JDBC Developer's Guide, 11g Release 2 (11.2)
Support for Data Encryption and Integrity
http://download.oracle.com/docs/cd/E11882_01/java.112/e10589/clntsec.htm#EHAFHEIG

Here are my complete steps:

1. First follow the steps to configure the database: - http://download.oracle.com/docs/cd/E11882_01/network.112/e10746/asoconfg.htm#i1006517

Depending on your selection, your 'sqlnet.ora' file should look something like this when finished:
