Does XWRITE create blocks?
Does XWRITE create blocks?
The @XWRITE function does just what it implies. It pushes the data from the source cube to the target cube rather than pulling the data from the source cube to the target cube. This pushing vs. pulling is beneficial for efficiency and block creation.
What is Xwrite?
@XWRITE Function XWRITE is a function that allows a calculation script to push data to another Essbase database or application (as opposed to XREF’s method of “pulling the data”).
What is XREF in Essbase?
Using Oracle Analytics Cloud – Essbase XREF is a calculation function you use to reference data in another cube, and XWRITE is a calculation function you use to write back data to another cube. The member containing the XREF formula can either be stored or dynamically calculated.
What is location alias in Essbase?
A location alias, which maps an alias name to the physical location of its database, specifies an Essbase Server, an application, a database, a user name, and a password. You can use aliases to refer to databases and can edit location definitions. You can use location aliases only with the @XREF function.
How do you make blocks in Essbase?
Blocks will be created when DATACOPY command is being used to copy values from one block to another. Equation / Formula: Blocks may be created when we have an equation or a formula in the scripts. When we assign a constant value to sparse dimension members, the block will be created.
Where is alias stored in Linux?
An alias is a (usually short) name that the shell translates into another (usually longer) name or command. Aliases allow you to define new commands by substituting a string for the first token of a simple command. They are typically placed in the ~/. bashrc (bash) or ~/.
What is block in Essbase?
Essbase stores data values in data blocks. Essbase creates a data block for each unique combination of sparse dimension members (providing that at least one data value exists for the combination). Each data block contains all the dense dimension member values for its unique combination of sparse dimension members.
How does Essbase calculate block size?
Multiply the number of stored members of the first dense dimension (line a) by the number of stored members of the second dense dimension (line b) by the number of stored members of the third dense dimension (line c), and so on, to determine the total number of cells in a block.
Where are my bash aliases stored?
They are typically placed in the ~/. bashrc (bash) or ~/. tcshrc (tcsh) startup files so that they are available to interactive subshells.
How do I check aliases?
All you need to do is type alias at the prompt and any active aliases will be listed. Aliases are usually loaded at initialization of your shell so look in . bash_profile or . bashrc in your home directory.
What is block and cell in Essbase?
Essbase creates a data block for each unique combination of sparse dimension members (providing that at least one data value exists for the combination). Each data block contains all the dense dimension member values for its unique combination of sparse dimension members.
How is data stored in Essbase?
Data values are intersections of members from different dimensions that are stored in one cell of the database. As mentioned above, Essbase accesses and stores data by using data blocks and an index system. A data block is created for every sparse dimension intersection.
What do you need to know about the @ xwrite function?
The following terminology is used to describe the @XWRITE function: Data source: the database on which the current calculation is running (that is, the database on which the @XWRITE call originates). Data target: the database that is updated by the @XWRITE function. This database may be remote (that is, on a different machine than the data source).
When to use @ xwrite in Oracle Essbase?
@XWRITE is a top-down formula. For more information on top-down formulas, see the Oracle Essbase Database Administrator’s Guide. @XWRITE to dynamic calc cells is not recommended; the data is calculated in memory, but not written. @XWRITE can be used in calculation scripts as well as outline member formulas.
Can you use same location alias in xwrite?
The same location alias can be used by both @XREF and @XWRITE. For @XREF, it represents the data source, and for @XWRITE it represents the data target. For @XWRITE only, a reserved keyword @LOOPBACK can be used to write to the same database. Optional.
Where do you put the fix in xwrite?
In writing XWRITE calculations, the FIX is as important as what is included in the XWRITE. The FIX will be where you define the area of data you want to move. The only dimension you will want to leave out of the FIX is the dimension you decide to use in the expression.
