SAP HANA SQL scripting optimization: the CE Functions

In SAP HANA, you have two possibilities to create the Calculated Views:

  • Using the graphical method
  • Using the scripting method with CE functions

In this blog, I will demonstrate that CE Functions can improve performances from a Calculated View.

Review: Ex Machina

Do yourself a favour and buy, beg, borrow (don't steal) the movie "Ex Machina".

OCM 11g Preparation – Assign jobs to windows

Instead of creating schedules and linking jobs to them, you can also define a job to run during a Window. So the job will start when the Window begins and you can also forcely stop it when the window ends.
Practice for this topic assigning a job to a window and a window group.

OCM 11g Preparation – Create job classes

Job classes are also templates for jobs, but instead of defining a standard “code” format, like PROGRAMS, with classes you pre-define the logs retention and capture standards, resource consumer and services.
For this item, practice creating a job class via EM and assign a job to it. Like programs, it’s less probable that this item will be requested via SQLPlus, but be also prepared for that.

OCM 11g Preparation – Create programs

Programs are like “templates” for job’s code. With a program you can pre-define the procedure/executable and arguments for a job. So, if you change your body code or call (let’s say you renamed or changed the location of the shell script that execute via JOB), all you need to do is to modify your PROGRAM instead of every job.
For this item, practice creating a program via EM and assign a job to it. It’s less probable that this item will be requested via SQLPlus, but be also prepared for that.

Untrusted X11 forwarding

I wrote a while ago about my security concerns regarding


xhost +
