DS - Define Size of Storage Buffer

This Natural profile parameter defines the default initial size of various Natural storage buffers.

In previous versions of Natural, individual profile parameters (for example, SSIZE) were used to define the sizes of the buffers. The DS profile parameter is a universal parameter to specify all buffer sizes. It corresponds to the NTDS macro in the Natural parameter module NATPARM.

See also Natural Storage Management and General Rules for Parameter Usage in the Operations documentation.

Anmerkung:
There are some buffer sizes (for example, ESIZE, VSIZE, etc.) which cannot be specified by the profile parameter DS, due to certain reasons, for example, the size is part of a larger buffer or the size defines the total maximum of a number of buffers.

Possible settings	`(name,size)`	`name` is the buffer name (1-8 characters), see Table of Buffer Sizes below. `size` is the buffer size in kilobytes. For limit values, see Table of Buffer Sizes below.
Default setting	See table below.
Dynamic specification	yes	Multiple pairs of buffer names/sizes can be specified. This parameter can only be specified dynamically. In the Natural parameter module `NATPARM`, the corresponding macro `NTDS` must be used instead.
Specification within session	no

You may continue using the individual parameters or you may use the individual parameters in parallel to the parameter DS. During the dynamic parameter evaluation, individual buffer size parameters are converted internally into the new DS parameter format, for example, SSIZE=55 is converted into DS=(SSIZE,55).

The following topics are covered below:

Examples

DS Parameter Syntax

The DS parameter is specified as follows:

DS=(name1,size1,name2,size2,...)

NTDS Macro Syntax

The NTDS macro is specified as follows:

NTDS name1,size1
NTDS name2,size2
...

Table of Buffer Sizes

Buffer Name	Description	Buffer Size (KB)	Default	Available as subparameter of `DS` and alternatively as individual profile parameter
`ASIZE`	Entire System Server auxiliary buffer	`0, 1-64`	`0`	yes
`BSIZE`	Size of EntireX Broker buffer	`0, 1-64`	`0`	yes

`DSIZE`	Initial size of debug buffer	`0, 2-2097151`	`2`	yes Anmerkung: The individual profile parameter `DSIZE` allows you to set a maximum size in addition.
`EDPSIZE`	Size of the Software AG Editor auxiliary buffer pool	`0, 48-2097151`	`0`	yes

`RUNSIZE`	Size of runtime buffer	`10-64`	`16`	yes
`SSIZE`	Size of Software AG Editor buffer	`0, 40-512`	`64`	yes
`TSIZE`	Size of the buffer for Adabas Text Retrieval	`0, 1-2097151`	`0`	yes
`XSIZE`	Size of buffer for user subsystem	`0, 1-64`	`0`	yes
`ZSIZE`	Size of Entire DB buffer area	`0, 1-64`	`0`	yes

For more information, refer to the descriptions of the individual buffer size parameters.

Examples

Example of DS parameter:

DS=(ASIZE,33,TSIZE,60,EDPSIZE,500)

Equivalent in Natural parameter module NATPARM:

   NTDS ASIZE,33 
   NTDS TSIZE,60 
   NTDS EDPSIZE,500
