Now certified! DB1-C01 - AWS Certified Database - Specialty

I finally got the email through from the AWS Training group that I had passed the DB-C01 exam and I am now officially Certified! Hurrah!

It took 2 months to the day to get the results through. I'm very pleased with the result and am looking forward to getting to put some of this knowledge into practise!

Data pump - "ORA-39786: Number of columns does not match between export and import databases"

Today I was asked if it was possible to import data for a specific table from a data pump export file, which was taken from when a table had a different structure to what it has now. e.g. when the export was taken, there were 10 columns.  Now there are 11. I thought that was simple, and I was sure I'd heard of this being done before.  Simply import using the "CONTENT=DATA_ONLY" parameter.  Right? Apparently not: Centos-/home/oracle/demo> impdp DEMO_USER/yyyyyyy directory=INBOUND dumpfile=demo_data.dmp logfile=impdpdemo.log content=data_only tables=xxxxxxxx Import: Release 10.2.0.4.0 - 64bit Production on Tuesday, 08 July, 2014 14:32:20 Copyright (c) 2003, 2007, Oracle.  All rights reserved.

APEX, SERT, and EPG

APEX, SERT, and EPG Application Express, Security Evaluation and Recommendation Tool, and the Embedded PL/SQL Gateway My organisation has only just started seriously working with APEX and have recently launched our first internal production app (that was a challenge... I was told that this app needed to be in production in 2 days and nobody had bothered to check with me what was needed to make this happen).  I've learned a lot about APEX in the past few weeks and I've got a lot more to go. I recently came across SERT ( https://github.com/OraOpenSource/apex-sert ) and it sounds like a really nifty tool.  Today I found some time to try it out and see if our dev team might find it useful.  I decided to install it in our dev database.  This uses the EPG rather than ORDS. The install didn't go so well.  The first install failed near the end because I think I used a lowercase 'y' for a response somewhere and it got confused, bombing out with an ORA-06502...
