Oracle Database Fun and Games

I've been working with a number of Oracle databases lately and decide to post some of the tips and tricks that I found:

SQL Developer
Error when you connect to database:
"Status : Failure -Test failed: ORA-00604: error occurred at recursive SQL level 1ORA-01882: timezone region not found"
Solution: Edit the sqldeveloper.conf file and add the following line:
AddVMOption -Duser.timezone=GMT

Error, running out of RAM
Solution: Edit the sqldeveloper.bat file and change the following parameters as required:
-Xmx640M -Xms128M
You can also set the -XX:MaxPermSize setting in the sqldeveloper.conf file, but I have not had to increase this yet.

Start Database Script
Old but good article here -> http://tldp.org/HOWTO/Oracle-7-HOWTO-6.html
Basically you need to do this:

Start the listner: lsnrctl start listener

Start Enterprise Manager: emctl start dbconsole

Set the SID of the database: export ORACLE_SID=report

Connect to sqlplus: sqlsplus "sys as sysdba"

Run the startup command: startup

Get list of tables
select tname from tab

Delete all tables
select 'drop table '||table_name||' cascade constraints;' from user_tables; ref

Stop it from prompting you for input values due to the & character
set define off

Cool tool to create new database
dbca (ssh -X into the server and run this command)

Novell IDM Convert Structured Attribute

Every time I need to work with structured attributes on a driver I land up googling for that same page of how to convert a structured attribute to a string and vice verse. Thus to save time I decide to post a link to the forum   here

The meat of the what you need to do to convert from a structured attribute to a string and back again is below, just remember to replace the attribute and component names as required:

Output Transform (struct -> string):
<do-reformat-op-attr name="faxnumber">
<arg-value>
<token-xpath expression='$current-value/component[@name="faxNumber"]/text()'/>
</arg-value>
</do-reformat-op-attr>

Input Transform (string -&gt; struct): 
<do-reformat-op-attr name="faxnumber">
<arg-value type="structured">
<arg-component name="faxNumber">
<token-local-variable name="current-value"/>
</arg-component>
<arg-component name="faxBitCount">
<token-text xml:space="preserve">0</token-text>
</arg-component>
<arg-component name="faxParameters">
<token-text/>
</arg-component>
</arg-value>
</do-reformat-op-attr>
