The SYSRPC CSMASS direct command
is used to calculate the buffer size RPC calls without intreface objects
require for sending data from the client to the server or vice versa. The
indication of the size helps you configure the middleware layer used; for
example, the Broker attribute file when EntireX Broker is used.
If desired, you can also perform size calculations for interface objects, even though sizes are already calculated when the interface objects are generated.
SYSRPC CSMASS can be used in
online or batch mode.
This section contains information on:
You can enter the command SYSRPC CSMASS at
any Natural command prompt for calculating size requirements online.
The section below contains information on:
The syntax that applies to the SYSRPC CSMASS
direct command is illustrated in the diagram below:

The syntactical items name and compression are explained in the section Name Specification and Compression.
The SYSRPC CSMASS direct command produces a
report that indicates the send and receive length requirements of the
subprograms (objects) specified with the command as shown in the following
example:

SYSRPC - Calculation of Buffer Sizes for RPC Without Interface Objects
Calculation Criteria:
Object name or range: RPC*
Compression: 1
Calculation Results:
Number of objects found: 8
Maximum send length: 200228
Maximum receive length: 1024192
Object Type Send Length Receive Length Message
-------- ---- -------------- -------------- --------------
RPCCALL1 N 209 202
RPCCALL2 N 219 240 Compression=2
RPCCALL3 N 204 193
MORE |
The report is organized in three sections, which contain the following information:
Calculation Criteria:
The criteria based on which the calculation was made: a single object
name or a range of names (here: RPC*) and the compression (here:
1).
Calculation Results:
The number of objects selected for the size calculation.
The maximum buffer sizes all selected objects require for sending and receiving data from the client.
Object List:
The name and type (here: N for type subprogram) of each
object selected for the calculation. The buffer sizes each object requires for
sending (Send Length) and receiving (Receive
Length) data from the client. A possible comment on each object
calculation in the Message column. In the example above,
Compression=2 indicates that object RPCCALL2 was not
calculated with Compression 1 as requested in the command. The object list is
sorted in alphabetical order of object names.
If the MORE prompt appears, choose ENTER to scroll to the end of the report.
If the size calculation fails for single or multiple objects, the report shows the number of objects affected and appropriate error messages.
You can specify the objects (subprograms) to be selected for size calculation and the type of compression to be used:
You can specify an object name or a range of names. If you do not specify a name or a range of names, the size of all subprograms contained in the current library will be calculated.
Valid name specifications are described below where value is any combination of one or more alphanumeric characters:
| Input | Objects Selected |
|---|---|
| * |
All subprograms. This is the default setting. |
| value | A subprogram with a name equal to value. |
| value* | All subprograms with names that start with value. |
| value< | All subprograms with names less than or equal to value |
| value> | All subprograms with names greater than or equal to value. |
You can specify any of the following compression types: 0,
1, 2. The specification of compression is optional.
The default type used for interface object generation is 1.
