Getting Started  The new Oracle REST Data Services SQL over REST.  How to enable that is on my last blog post here: http://krisrice.blogspot.com/2017/09/ords-173-beta-introducing-rest-enabled.html cURL Examples The simplest way to test this new feature out is with a curl command sending over the SQL. $ curl -X "POST" "http://localhost:9090/ords/hr/_/sql" \ -H "Content-Type:

Download Got get it on the normal ORDS download page http://www.oracle.com/technetwork/developer-tools/rest-data-services/downloads/index.html Versioning  First and most obvious is ORDS is now on the same versioning scheme as SQL Developer, SQLcl and Oracle Cloud.  That is <year>.<quarter>.<patch> and the same tail we've always had which is <julian day>.<HH24>.<MI>.  That makes this beta

NetBeans First, there's NO Java coding needed nor Java source code needed to profile a Java program this way.  NetBeans added this a while back up I just found it recently.  The ability to attach to any Java program and profile the SQL going across JDBC. The dev team's blog on it is here: http://jj-blogger.blogspot.nl/2016/05/netbeans-sql-profiler-take-it-for-spin.html SQLcl SQLcl is our

New Versioning Scheme Starting with this release the numbering scheme is changed.  All releases will now be the YEAR<period>Quarter<period>build numbers. So the new SQLcl is 17.2.0.184.0917.   Breaking that down.  17   - Year 2     - Quarter 0     -  Patch number 184 - Day in Julian 0917 - hour and minute the build was done. New Features Securing Literals  which was introduced

A while ago we needed to stress a system by using the APEX Brookstrut demo application.  The obvious choice for this was Jmeter.  How to setup Jmeter to record web traffic by becoming a web proxy is very known and well written process.  Anyone that hasn't seen it, check this PDF and you can see how easy it is. There were a couple issues to get around. First importing the application again and

TL;DR 1) check out https://github.com/krisrice/docker-ords-sqlcl-apex 2) Download ORDS ; optionally SQLcl,APEX 3) Build w/DB connection details docker build -t krisrice/ords:3.0.10 --build-arg DBHOST=192.168.3.119 --build-arg DBSERVICE=orcl --build-arg DBPORT=1521 --build-arg DBPASSWD=oracle . 4) Run the image docker run -d -p 8888:8888 -p 8443:8443 --name=ords krisrice/ords:3.0.10 5) Access

My last post How to add an NCSA style Access Log to ORDS Standalone explained what the ORDS standalone is and that is based on Eclipse Jetty.  Jetty offers far more than ORDS exposed in it's standalone.  There's a long list of all the features and configuration options listed in the documentation, http://www.eclipse.org/jetty/documentation/9.2.21.v20170120/ A recent question came up for doing

There seems to be some confusion around how ORDS works with it's connection pooling yet running the REST call as the specified schema. The connection pool Consider a 50 PDB env and concurrent users per PDB running some REST stuff.  Using a connection pool per PDB would be 50 connection pools.  Then if a JET app ( or any HTML5/JS/.. ) is making REST calls Chrome will do this with 6 concurrent

What ORDS Standalone is      ORDS Standalone webserver which is Eclipse Jetty, https://eclipse.org/jetty/ .  For the standalone, ORDS sends output to STDOUT, it runs on the command line.  That means there's nothing like a control commands like startup, shutdown,status nor log files, access logs.  It's bare bones intentionally to get up and running fast.  Then it's recommended for anything with

Another quick twitter inspired blog post inspired by the SQLcl account itself. Asked and answered: Do you support the ACCEPT command? YES. pic.twitter.com/NchmQ6Eegs — SQLcl (@oraclesqlcl) November 29, 2016 ACCEPT is a great way to get input but validation has to happen elsewhere as there's no hooks to do something like validate a number in a range without running a sql or plsql that does

This blog post brought to you by the letter M as in Martin . Follow @martindsouza . He asked me on twitter if SQLcl via Nashorn could use ECMA Script 6 features yet.  The answer is yes.  So, for the brave that want to try out the latest greatest ECMA Script 6 features it can be done with SQLcl. This is a good reference for what's in version 6 that could be useful.  The only caution is not

Hopefully by now everyone knows there's the ability in SQLcl to use Javascript and the same javascript can be used to make custom commands extending what SQLcl offers out of the box. Also, I hope everyone knows we are posting examples of this to github as a base for anyone to learn and try it out.  Just in case here's the link to the GitHub location https://github.com/oracle/oracle-db-tools/tree

I got a question over the weekend if SQLcl could be leveraged as library from inside a Jython program. This may seem like it's the same thing as adding jython to SQLcl to use instead of Javascript but it's a significant difference. This method allows for the use of SQLcl in any existing program. That means when the program needs to interact with the database, all the code in SQLcl that is tried

I saw Stephen's example of checking reserved words in the database from Vertan's day and figured I'd do the same in SQLcl. #595 #plsql Is it a reserved word? PL/SQL procedure to help you sort that out. Dyn PLSQL example! @oraclelivesql https://t.co/M10kVnsQ3y pic.twitter.com/XFFHOVzNCK — Steven Feuerstein (@sfonplsql) November 11, 2016 Checked if something is reserved seems like a nice add

APEXExport has been around a long time for exporting an application and anything else like images, feedback,websheets,.. into a file system so that they can be version controlled.  This is a must if there is ever a need to rollback or see what the application was X days ago.  This is a java program that is part of the apex distribution.  The catch for some folks is that it's a java program and

Defaulting  PL/SQL Gateway Security Oracle REST Data Services 3.0.7 went out yesterday.  There's an important change that went in to better secure installations by default.  It has always been the case that we recommend customers set the validations for the plsql gateway.  There has always been a validation configuration option to lock down what procedures are accessible which was outlined in

Seems I can not tweet these animated GIFs anymore. So this is another very short blog post to show real case for adding a new command into SQLcl which can be downloaded here. It's hard annoying tedious to find SID and SESSION then alter to kill that when needed.  What if there was a simple kill command. Here a sample one that takes in the 2 options:   kill sid serial#   Example :   kill 1 2 OR

The database has had Query Change Notification for a while but to use it required a custom program. Such as Tim outlines on his blog https://oracle-base.com/articles/10g/dbms_change_notification_10gR2 Since SQLcl has Nashorn, now it can be integrated with a few lines of javascript to get notified when changes happen.  The script is below and posted.  The catch is QCN only works on Varchars and

Here's a pretty small javascript file that allows for running sql in the background of your current sqlcl session.  This is a trivial example of a sql script that has a sleep in it to simulate something taking time. It also prints the SID to show it's a different connection than the base. select 'DB SID ' ||sys_context('USERENV','SID') || ' is going to sleep' bye from dual; begin

In case anyone missed it, #sqlcl has the ability to run javascript. This opens a lot of options.  Here's a simple example that shows how to using javascript. Open a new Database Connection Collect stats on the base connection Do work on the main connection Collect stats again Only Print the stats that changed In SQL Developer, the autotrace feature has for a long time selected the session
