So I haven’t written to my blog since long and that’s just because I just did not find anything worthwhile all these days. Today I encountered a strange issue. So I thought to share with you guys. We had a Planning web form set to input data. No Business Rules or calc scripts attached. Just an input form. The issue : Every time any user enters the data into the form it says the data is saved but does not show up the data. Causes: Probably one would think this might be a simple case of Implied Sharing or usage of a label only parent member with one of the single child only hierarchy in the form.. sure thing .. SO DID I!! Its simpler than that! Another weird behaviour: data is saved and reflects in the web form when I enter and submit through the Smart View Planning add-in So what is the issue: the layout of the web form! The data form was designed to check data values at CurrYr and NextYr. However the current year and next year were both set to the same value.

While running an Aggregation process or a restructure in essbase have you ever encountered either of these: EAS quits accepting logins Essbase going down time and again. Failed Data load / Failed Data Export / Failed Level 0 export All of the above together :) In all these cases, there is a huge possibility that you are facing creation of tmp files issue on your Essbase Server, specifically if you are on Linux The Temp directory contains mostly files that are required temporarily. Many programs use this to create lock files and for temporary storage of data. Do not remove files from this directory unless you know exactly what you are doing! Many of these files are important for currently running programs and deleting them may result in a system crash. Usually it won't contain more than a few KB anyway. On most systems, this directory is cleared out at boot or at shutdown by the local system. In MS-Dos  and Windows , the temporary directory is set by the environment

Below concepts involve Data Blocks in some way or the other, so to understand how Data Blocks behave it’s good to understand these concepts: Let's Begin!! Compression Clean and Dirty Blocks Fragmentation Restructure Compression: When Essbase stores blocks to disk, it can compress the data blocks using one of the following compression methods, this is based on the type of data that is being loaded into the Essbase database. Essbase provides several options for data compression: 1. Bitmap compression : This is the default compression method. Essbase stores only non-missing values and uses a bitmapping scheme. A bitmap uses one bit for each cell in the data block, whether the cell value is missing or non-missing. When a data block is not compressed, Essbase uses 8 bytes to store every non-missing cell. 2. Run-length encoding (RLE): Essbase compresses repetitive, consecutive values --any value that repeats three or more times consecutively, including

O2B Utility There are  times when we have to query the Hyperion Planning Application's relational database to get the Auditing reports, alas! we don't have an option to get them from our Planning interface. Many times we have wondered how to get the list of dimension members, data forms, there layouts, users security reports, task list status, supporting details, account annotations etc. What if there is a web based utility to take care of all this and more....!! My good friend, Rahul Sharma has taken the effort to design this utility .. Pleased to share the details on my blog: Let's start working on O2B Utility: http://hyperionplanningandmore.blogspot.in/2014/09/lets-start-working-with-o2b-utility.html What is O2B and How its useful to me ??? http://hyperionplanningandmore.blogspot.in/2014/09/what-is-o2b-and-how-its-useful-to-me.html How to deploy it to Weblogic: http://hyperionplanningandmore.blogspot.in/2014/09/deployment-of-o2b-on-webl

An Essbase outline has a number of dimensions.  The number of dimensions can range in quantity and size, but each dimension is identified as a dense or sparse dimension.  As we understood the concept of Dense and Sparse in our last discussion, let’s begin with the cocept of data blocks now. To understand this, let’s carry forward our hierarchy of 5 dimensions in a test application in my previous post.. We have 3 dense and 2 sparse dimensions each with 3 stored members. So let’s begin: Number of Existing Blocks = (potential number of blocks) * estimated density= 9 Block Size = Dense Stored * Dense Stored * Dense Stored * 8 bytes = 3*3*3 *8 = 216 Potential number of blocks = Sparse Stored * Sparse Stored = 9 If all dimensions are assigned as Dense, Number of Existing Blocks = (potential number of blocks) * estimated density= 1 Block Size = Dense Stored * Dense Stored * Dense Stored * 8 bytes = 3*3*3*3*3 *8 = 1944 Potential number of blocks = Spar

So what is Dense and Sparse Dimensions?? Essbase outline has a lot of components. One of the most important components is Dimension. Dimensions are the representations of business components and might be of standard or attribute types. Standard Dimensions are basically of two types: Dense & Sparse. So basically by oracle documentation, “A dense dimension has a high probability that one or more cells is occupied in every combination of dimensions.” “A sparse dimension is one with a low percentage of available data positions filled.” However, the above definition is valid only with reference of data positions or data cells filled or not. What about the case when we do not have any data. How does Essbase identifies whether the added new dimension is a Sparse or Dense.. To understand that I did a simple test. We create an application from scratch with just some random dimensions “A”, “B”, “C”, and “D” without any children. Then we check how Essba
