Topic: VPCLASS

I want to understand:
IDS 10 and above
In docks it is written that it is possible to create many different classes of the virtual processors (adm adt cpu kio lio msc opt lio shm soc str tli), by default for operation describe vpclass cpu and if is present DBSERVERALIASES c soctcp the class soc is launched that proves to be true statistics onstat-g glo.
Question: if use access through Shared-Memory, whether it is necessary to me in onconfig to add
VPCLASS shm?
And if it is used two access types through TCP and Shared-Memory - it is necessary to add also
VPCLASS soc? So in dock it is written that class VPCLASS shm should is processed NETTYPE ipcshm, x, x, NET
. in an ideal:
VPCLASS cpu
VPCLASS shm
VPCLASS soc
And
NETTYPE ipcshm, x, x, NET
NETTYPE onsoctcp, x, x, NET
But in normally put (even in onconfig.std)
VPCLASS cpu
And
NETTYPE ipcshm, x, x, CPU
NETTYPE onsoctcp, x, x, NET
Probably VPLASS CPU - general-purpose, and remaining only for convenience - to classify all
Where true?

Actually there is no choice in spreading out
NETTYPE it is necessary to carry out with CPU VPCLASS.
At   architecture with  the singularities.
Also it is necessary to consider the scheduler - as Informiks and OS.

Well though so, thanks
It would be desirable to learn certainly as all reflected the vendor, but it is similar here only guesses
In the beginning most likely there was access Shared-Memory, then with development of network technologies, started to saw onsoctcp
The documentation in Russian translation informs the following:
Table 5-1. Classes of the virtual processors
ADM administrative Performance of administrative functions.
ADT audit Performance of functions of audit.
AIO disk input-output Performance of the disk input-output which has been not connected to guiding of log.
If it is used KAIO, the virtual processors AIO fulfill
Input-output operations for  disk spaces.
BTS Basic text search Performance of operations of an index of basic text search and handling
Requests.
CPU Centralized
Handling Performance of all flows of sessions and some system flows.
Performance of a flow for asynchronous input-output of a kernel (Kernel
Asynchronous I/O - KAIO) if it is possible. Performance is possible
One flow of inquiry depending on a configuration.
CSM the Unit of support of communication Performance of operations of support desks of communication.
Encrypt Enciphering Is used by the server of databases by a call of functions of enciphering and
Decryptions.
Java VP (JVP) Java UDR Performance Java UDR. Contains Java Virtual Machine (JVM).
LIO disk input-output Record in files of logical log (an internal class), if they
Are in  a disk space.
MSC the Miscellaneous of the Requirement of services for system calls it is required which very much
The big stack.
OPT (UNIX) the Optical subsystem Performance of input-output operations of an optical disk.
PIO disk input-output File recording of physical log (an internal class) if it is
In  a disk space.
SHM the Network communication Realization through joint storage.
SOC the Network Realization of network interactions with usage of slots.
TLI the Network Realization of network interactions with interface usage
Transport Layer Interface (TLI).
==========================================
. SHM the class is and on my logic it is necessary to use it (with it will be better or worse not clearly)
Most likely at small loading it will be not noticeable, when CPU the class is engaged in not the business
When this class is not described - for it works CPU a class.

What for  which problems is not present?
Informix it not  for which it already is a lot of 100 users.
For many thousand users the multiplexer of connections which is bought separately can be demanded.

For many it how many (> ~32 or how)?
