When a whole number needs conversion to a fully spelled out format, the wellknown J/JSP “tric” is readily found. Well, in case, you didn’t, here it is. No, it has nothing to do with Java Server Pages.
When work gets done during business days, that’s what this blog post is about. Moreover, when also the amount of business days is known upfront.
I have been working a lot with Oracle’s GoldenGate the last year or so and i am loving the product more and more. I really enjoy it’s modulair format where you can actually form it into exactly the thing that you need. However one thing about working with GoldenGate is something that always annoyed me a bit: There is no good way of finding out where the binaries are if the GoldenGate processes are not running. Coming from an Oracle database background, i am used to an oratab file or a cluster registry to see where a database is running (or not running).
Recently i had to reimage a couple of Exadata compute nodes for different reasons like an almost simultaneous failure of 2 harddisks in the compute node.
A lot of customers of mine who are starting with Oracle Golden Gate have issues when it comes to troubleshooting Golden Gate. It is the most common question i get: “I have setup Golden Gate, it was working fine but now process X abandoned… now what do i do?”. The OGG error log is a good starting point but is not always showing the real issue. There are a lot different way to obtain more information on why you are running into an issue. In this blogpost i want to introduce a maybe not so well known feature called Golden Gate Activity Logging Tracing and yes that is how they are really calling this feature.
In my previous 2 blogposts i explained how to setup a Vagrantfile that deploys 2 virtualbox machines that can be used as a basis for a RAC cluster and how you could use Ansible to deploy RAC on those VM’s. In this post i want to dive a bit deeper into how i setup Ansible and why, keep in mind that this just one way of doing this.
Creating your own test VM environment with RAC is a fun exercise to do, however after you have rebuild your environment a couple of times this will get a very tiresome exercise and you want to start to automate your deployments. People have already written several blogposts about the GI and RDBMS orchestrations and the several tools that are available for this. Within the Oracle community Ansible seems to be a very popular choice for the part of getting your test environment up-and-running. But what about the part to get your VM up-and-running, a very repetitive task and not a very interesting task to say the least.
You have a procedure or function returning computed values in out parameters. And you’d like to call it in SQL. How’s that done?
Suppose you are the developer of a database service which can be called any number of times. This database service itself just registers the call, and is allowed to immediately make an outbound call to another service, for example to enhance information presented by the initial inbound call.
How to invoke SQL and/or PL/SQL scripts from Notepad++
Notepad++ might well be your one and only text editor. It’s your favourite editor too, right? But can you run your Oracle SQL*Plus or Oracle PL/SQL commands or scripts from within npp++ at a click of a button ? Yes you can.
