Contents. In order to ensure optimal database performance, it is important that you assess your storage needs and plan accordingly. This section will help you to do this and is comprised of the following topics:.

Planning for Table and Index Storage Planning the storage of tables and indexes is best done during the physical design stage in order to improve performance and to streamline data administration tasks. When planning physical storage, carefully consider both the placement and size of tables and indexes. The performance of almost all database applications is I/O bound. To improve I/O throughput, physically separate tables that are frequently joined together. Also, separate tables from their indexes. The objective is to have the database read or write data in parallel as much as possible.

How to find out the size of the datafile for a database consist of three tables with following specs. How to size database ( Excel File Included) If this is your first visit.

Two key concerns of every database administrator are free space management and data fragmentation. If you do not properly plan for the volume and growth of your tables and indexes, these two administrative issues could severely impact system availability and performance. Therefore, when designing the physical model, consider the initial extent size and logical partition size.It As a starting point, estimate the size of each table and its indexes based on a projected row count. The Capacity Planning tool helps project the size of the databases given certain growth parameters.

For databases that let you specify initial extent sizes, such as Oracle, set the initial extent size to the estimated size in order to avoid data fragmentation as the table grows. By keeping tables within a single extent, data access times decreases and table reorganization can be determined. Once you have determined the placement and sizes of the tables and indexes in your database, estimate the total size requirements of the database in order to avoid running out of free space for the database. Predicting Table Growth Capacity planning metrics can be recorded for each table so that proper sizing can be done before the table is implemented in a database. The Capacity Planning tab of the Table Editor helps predict change using metrics such as table row count, table growth rate, growth type, growth period and table maximum size. In the Data Model Explorer, double-click a table in the physical model. Click and then complete the Capacity Planning tab.

Tip: Change the column Avg. Width and Percent Null values to more accurately predict the table growth. The growth predictions you make in the Table Editor display in the Capacity Planning utility and can be edited there. Predicting Database Growth Using the Capacity Planning utility, you can forecast storage requirements of newly implemented or existing database systems so budgeting or engineering can be accounted for well in advance.

In the Data Model Explorer, select and then right-click a physical model. Click and then complete the Capacity Planning utility. The following describe options that require additional explanation:. Sizing Options tab: Index Options: Select any of the following options: Primary Key (PK), Foreign Key (FK), Alternate Key (AK), and Inversion Entry (IE). Growth Parameters tab: Specifies overhead elements that contribute to database growth.

The amount of overhead required depends on the DBMS platform and the storage options you have selected for the database, such as the minimum percentage of a data block to reserve as free space, and options for logging, auditing, and data recovery. The values provided here are reflected in the Projected Size column of the Growth Analysis tab. Row Overhead: Tailors the formulae to account for any overhead used by the chosen DBMS platforms of the physical model to store each record. This number represents the number of bytes of overhead the DBMS may use to store records. This should be set to 0 initially, but you can specify any number of bytes to add on to the row size.

Table Overhead: Accounts for overhead to store data for a table. This is a multiplier applied to table size.

A value of 1.2 corresponds to 20% overhead. The default value of 1 indicates no overhead. Index Overhead: Accounts for overhead to store indexes.

The number of bytes is added to the indexed column sizes. For example, in Oracle the index overhead is 6 bytes, so 6 is added to the sum of the indexed column sizes. Blob Overhead: Accounts for overhead to store BLOB columns. Similar to Table Overhead, this is a multiplier applied to BLOB storage. A value of 1.2 corresponds to 20% overhead. 1 indicates no overhead.

Blob BlockSize: Enter an estimate of the average size of BLOB columns. This will be used as the average size of each BLOB column. Note:. Changes you make for a table on the Sizing Options tab are automatically reflected in the Sizing Estimates, which is also displayed this tab.

Changes made to all Sizing Options and Growth Parameters are reflected on the Growth Analysis tab. The capacity predictions you make in the Capacity Planning utility display in the Table Editor and can also be edited there. Reporting Database Growth Analysis From the Capacity Planning Utility you can export the metrics produced in formats such as RTF or CSV, so, for example, you can draft your own reports for the growth patterns of a physical model.

In the Data Model Explorer, select and then right-click a physical model. Click Capacity Planning and then complete the Sizing Options and Growth Parameters of the Capacity Planning utility.

Click the Growth Analysis tab and select the Report Type and Report Options desired. A preview of the report contents appears in the Output area. See Also.

I can not even recall how many times I was asked by a customer what size the machine should be bought to run our Software. Unfortunately Tech Support is not even the right address to answer that question, as a purchase decision is closely tied to the answer.

Hence, Tech Support has been limited to the answer: 'The biggest machine you can afford':). Many Customers were unhappy with that and have tried to get us to be more precise and that causes a lot of explanation and lengthy discussion. In the end no one is wiser or happier. Therefore I am happy to report that at least for OBIEE the decision has just been made a whole lot easier. Have a look at the note The document attached to that note gives you a good overview for teh sizing of the machines that Oracle recommends to run OBIEE (be it a small installation or a bigger distributed installation) If you have any more questions about this topic and what machines we recommend, then get in contact with or speak to your sales representative.
