VMware Workstation - [Bug] Leaking Comitted Memory

Wednesday, May 3, 2017

Introduction

Personally I use VMware Workstation 12 allot for building EPM environment for testing and developing reasons. Today I discovered a nasty issue, which appears to be a bug.

Issue Description

When using VMware Workstation v12.5.x on Windows 10 with the creative update installed, the virtual print driver leaks committed memory over a short period of time to a 100%. Only Windows based VM's seem to be affected.

I confirmed that e.g. Linux based VM's are not effected. From personal experience Windows Core based VM's also seems to be OK, but I cannot 100% confirm this.

Solution / Workaround

VMware is still investigating the issue, however in the mean while disabling virtual printing in VMware Workstation seems to be a valid workaround.

GeekStuff (EPM): Oracle EPM HFM 11.1.2.4 and Oracle DB 12c

Tuesday, March 28, 2017

Introduction

At the time of writing the latest available PSU .204 for HFM does not support Oracle Database 12c yet. Although it works well, it doesn't work out-of-the-box.

Can't wait for Oracle to officially support Oracle DB 12c? Read on!

Geek Stuff (EPM) - Undocumented Parameters EPM Diagnostics Utility

Wednesday, November 30, 2016

Introduction

Since Oracle EPM 11.1.2.0 Oracle has introduced EPM Diagnostic Utility (validate.bat). For the newbies, the EPM diagnostic utility is a java based tool with the purpose to technically validate an EPM instance. Executing this utility results in two things: A full HTML diagnostics report, and a ZIP file containing all log files from the instance it was executed from. The Oracle EPM documentation related to this utility can be found here.

Since Oracle EPM 11.1.2.3, the EPM diagnostic utility is a good start when validating a installation or troubleshooting issues. However there are some minor downsides: It always performs all tests, always creates a ZIP file after completion and there is not option to selectively test... at least so I thought.

For an automation project, this default behavior was a problem. As such, I examined the java code related to the EPM diagnostic Execution and discovered that it excepts various command line parameters borrowed from the EPM installation utility wizard.

How to configure CPU options in the UEFI (BIOS) for maximum Essbase calculation speeds

Thursday, September 22, 2016

Introduction

Personally I never paid attention to specific UEFI (Unified Extensible Firmware Interface) settings when installing and configuring EPM. It was always on factory default values. During a project however, I was triggered to have a look at these setting due to an issue I could not explain.

What I discovered, came as a big surprise to me!

Planning Tutorial: How to deploy Planning Utilities Standalone!

Monday, July 4, 2016

Introduction

If you ever had to publish Planning utilities for administrators in e.g. Terminal Server or Citrix, you experienced the difficulties of doing that. Planning utilities can only be executed on the server where Planning is installed. Solutions to provide access to these utilities range from full administrative (RDP) access on the Planning server to PowerShell scripts using remote execution. In my experience non of these solutions are ideal and at best cumbersome to maintain.

Already for a few years I though: "There must be another way".

... and now there is!
