During one of the sizing exercise the ask for server capacity was more than the actual usage of cluster . Knowing the data and usage, I was not convinced that we should be asking for more memory space. That triggered the thought of
Conceptually FSIMG file is the balancesheet of all the file and their existence and location. If somehow we could read the metadata withing the file and make sence out of it, than it could help (more...)
We had a requirement of tracking a query fired from OBIEE. This was to help us find out the Analysis that consume the most database resources.
It is possible that some user might be selecting a huge date range resulting in the problem at the database. So the trouble in this case might be (more...)

Since the requirement is strange so will be the solution.
One option is to create the shortcut of each page and then hide the dashboard. This option is recommended but will lead to creation of a shortcut for each page.
To enable tunneling for use with Discoverer Plus, use this workflow:
- Launch Enterprise Manager using something like: http://server.domain.com:7002/em

While we all know about using conditions on sections in a dashboard, and while we all have used presentation variables to show or hide a report using these conditions, this blog talks about a process to use conditions on sections to implement a 3 way decision rather than just a boolean (true/false) decision.
Lets say that we have to show one section based on one value of a presentation variable, another based on another value (more...)

In this blog post we look at how we can address a shortcoming in the Hive ALTER TABLE statement using parameters and variables in the Hive CLI (Hive 0.13 was used).
There’s a simple way to query Hive parameter values directly from CLI
You simply execute (without specifying the value to be set):
SET hive.exec.compress.output; --- hive.exec.compress.output=false
You may use those parameters directly in (more...)
