How to change the number of web service threads

Last update: 22 October 2018

Information

The Fabasoft Folio web service handles incoming requests in a thread pool. This article describes how to change the number of threads in the thread pool in case of a necessity.

Windows

Set the Registry Key „ HKEY_CURRENT_USER\Software\Fabasoft\Environment\FSCVEXT_MAXTHREADS „ and the Value „(Default)“ to the number of Kernel Threads.

Example

       Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Fabasoft\Environment\FSCVEXT_MAXTHREADS]

@="16"

After an IISRESET your changes will be applied.

NOTE

You have to be logged in with the Fabasoft Folio web service account.

Linux

Change the line „Threads“ in your /etc/fabasoft/web/mpm.conf to the desired number of threads, and create the folder „/etc/fabasoft/settings/users/fscsrv/Software/Fabasoft/Environment/FSCVEXT_MAXTHREADS „ and the file „ registry.default „ within that folder, containing the desired number of threads.

Example

1) vim /etc/fabasoft/web/mpm.conf

RHEL6/CentOS6

In that operating systems, only the Threads parameter needs to be adjusted:

       #

# Server-Pool Size Regulation (MPM specific)

#

## worker MPM

# StartServers:        initial number of server processes to start

# MaxClients:          maximum number of simultaneous client connections

# MinSpareThreads:     minimum number of worker threads which are kept spare

# MaxSpareThreads:     maximum number of worker threads which are kept spare

# ThreadsPerChild:     constant number of worker threads in each server process

# MaxRequestsPerChild: maximum number of requests a server process serves

  StartServers         1

  ServerLimit          1

  MaxClients           8

  MinSpareThreads      8

  MaxSpareThreads      8

  ThreadsPerChild      8

  MaxRequestsPerChild  0

## async MPM

# Threads:             number of worker threads (default: 8)

  Threads              16

RHEL7/CentOS7

In that operating systems, all the keys MaxClients, MinSpareThreads, MaxSpareThreads, ThreadsPerChild and Threads needs to be adjusted:

        #

# Server-Pool Size Regulation (MPM specific)

#

## worker MPM

# StartServers:        initial number of server processes to start

# MaxClients:          maximum number of simultaneous client connections

# MinSpareThreads:     minimum number of worker threads which are kept spare

# MaxSpareThreads:     maximum number of worker threads which are kept spare

# ThreadsPerChild:     constant number of worker threads in each server process

# MaxRequestsPerChild: maximum number of requests a server process serves

  StartServers         1

  ServerLimit          1

  MaxClients           16

  MinSpareThreads      16

  MaxSpareThreads      16

  ThreadsPerChild      16

  MaxRequestsPerChild  0

## async MPM

# Threads:             number of worker threads (default: 8)

  Threads              16

2)

       mkdir /etc/fabasoft/settings/users/fscsrv/Software/Fabasoft/Environment/FSCVEXT_MAXTHREADS

echo -n "16" > /etc/fabasoft/settings/users/fscsrv/Software/Fabasoft/Environment/FSCVEXT_MAXTHREADS/registry.default

chown fscsrv.fsc /etc/fabasoft/settings/users/fscsrv/Software/Fabasoft/Environment/FSCVEXT_MAXTHREADS -R

After restarting your Fabasoft Folio web service the changes will be applied.
