[AdministrativeConnectionProperties] Section

Property Name Supported In Restrictions Description
Email 0 <= Length <= 255 Server administrator's email address
MaxConnections 0 < Value <= 1024 Max # of open administration connections
Port Port to use for administration operations.
WARNING: If you change the port # here you must also
change the corresponding port # in webconfig.ini
QueueSize 0 < Value <= 1024 Max # of administration operations to queue
ThreadPoolSize 0 < Value <= 1024 # of threads available for processing administration operations

MaxConnections

MaxConnections determines the maximum number of web tier connections the server will accept. For MapGuide 2.1 and earlier on Windows, the total number of connections (administrative + client + site) must be no greater than 62 connections. On the 63rd connection attempt, the server will become unresponsive. For MapGuide 2.2 on Windows and all versions of MapGuide on Linux, the supported connection limit is greater than 500 connections.

To fully utilize all cores on a MapGuide server machine, there should be 1 administrative, 3 client, and 2 site connections per core. Assigning additional connections may reduce request queue lengths and better utilize server resources if longer delay features sources like WMS, WFS, and databases are used. For local on-disk feature sources like SDF and SHP, the 1/3/2 per core listed above will typically be sufficient.

QueueSize

The request queue size should be set to at leat MaxConnections - ThreadPoolSize. Setting the queue size too low could lead to request loss under heavy load.

ThreadPoolSize

To fully utilize all cores on a MapGuide server machine, there should be 1 administrative, 3 client, and 2 site threads available per core. Increasing the thread pool size further may reduce request queue lengths and better utilize server resources if longer delay features sources like WMS, WFS, and databases are used. For local on-disk feature sources like SDF and SHP, the 1/3/2 per core listed above will typically be sufficient.

DataTransactionTimeout 0 < Value <= 1800 Time duration in seconds for when an idle FDO transaction is dropped
DataTransactionTimerInterval 0 < Value <= 1800 Time interval in seconds for when the server checks for idle FDO transactions

CacheSize

The MapGuide Server uses schema and class definition information in many requests. Caching this information locally increases server throughput and increases the memory footprint. CacheSize controls how many objects the server will cache. If sufficient memory is available, the CacheSize should be set to the total number of feature classes visible from all feature sources.

DataConnectionPoolExcludedProviders

By default, SDF data sources do not use pooled connections. This allows read/write operations to occur. Some performance improvement can be obtained by enabling connection pooling for SDF and SHP. Note: Turning on connection pooling for SDF will make SDF unsuitable for FDO update operations. If temporary layers are constructed using SDFs, connection pooling must be disabled for SDF.

DataConnectionPoolSize

Pooled connections allows the MapGuide Server to reuse existing connections to FDO feature sources. Database connections are created once and reused for multiple requests. Typically, two connections per core is sufficient to obtain full utilization of the cores on the MapGuide Server. Please note: Many FDO providers maintain schema for each connection. This increases the memory footprint as more connections are opened.

DataConnectionPoolSizeCustom

Pooled connections can also be set on a per-provider basis. This can be used to increase the connection pool for specific providers, like databases, while leaving the other providers alone. See DataConnectionPoolSize for tuning considerations.

SessionRepositoriesLimit The total number of active session files allowed. This setting only works when FilePerSession is used.
SessionRepositoryPath Path where the Session repository is stored
SessionResourceDataFilePath Path where the Session resource data files are stored

RepositoryCheckpointsTimerInterval

The repository checkpoints timer interval determines the time between successive Resource Service database checkpoints. While a checkpoint occurs, all database writes are suspended. This can lead to freezes in client UI interaction as the Web Tier waits for the Session Repository to accept writes. Reducing the checkpoint interval will increase the number of freezes that occcur in a given time interval and will also reduce the time per freeze. If the database checkpoint takes too long, some operations will timeout and users may experience unexpected behaviour. Please note: Very large concurrent user loads are needed before checkpoint freezes become noticeable.

[SiteServiceProperties] Section

Property Name Supported In Restrictions Description
SessionTimeout 0 < Value <= 86400 Time duration in seconds for when an idle session is expired
SessionTimerInterval 0 < Value <= 2147483647 ime interval in seconds for when the server checks for idle sessions

SessionTimeout

The session timeout determines the maximum idle time for a session. Once the idle time has been reached, the session will be deleted from the session repository. The MapGuide Server keeps a portion of the session repository in memory and flushes least used pages to disk. A shorter idle time will delete sessions more rapidly and reduce page flushing. The page flush occurs during repository checkpointing.

SessionTimerInterval

The session timer interval controls how often the session repository is checked for idle sessions. This value should be set to 1/2 or 1/3rd of the session timeout to ensure that ide sessions are removed on a regular basis.

Webconfig.ini

Overview

Webconfig.ini controls various aspects of the MapGuide WebExtensions and MapAgent. It is typically located in C:\Program Files\OSGeo\MapGuide\Web\www or /usr/local/mapguideopensource/webserverextensions/www.

[GeneralProperties] Section

Property Name Supported In Restrictions Description

FailoverRetryTime 2.2(+) Time in seconds for when to retry connecting to a MapGuide server that has gone offline.

FailoverRetryTime

For a single Web Tier and MapGuide server pair use 1. For a load balanced configuration with multiple MapGuide servers use 60. Values other than 1 will cause a delay when re-establishing a connection with the Web Tier after restarting a MapGuide server.

[AdministrativeConnectionProperties] Section

Property Name Supported In Restrictions Description
MaxConnections The maximum allowed concurrent connections for this port.
Port The port to use for administrative operations. If you change the port # here you must also change the corresponding port # for the server configuration file.

MaxConnections

The default values in the table below are applicable for a typical user load and a single web tier process space connected to a quad core server. In MapGuide 2.1, the MapGuide server on Windows can only support 62 open connections. Heavy user loads on Windows may create multiple web tier processes and exhaust the available connections with the default settings. MaxConnections may need to be reduced under these circumstances. For MapGuide 2.2 and later, the MapGuide server can support more than 500 connections.

Connection Type Platform Default Value Tuning Considerations
Administrative MapGuide 2.1 Windows 2 Reduce to 1 if server becomes unresposive under heavy load
Client MapGuide 2.1 Windows 12 Reduce to 6 if server becomes unresposive under heavy load
Site MapGuide 2.1 Windows 6 Reduce to 3 if server becomes unresposive under heavy load
Administrative MapGuide Linux (all versions)
MapGuide 2.2 Windows
2 Set to 0.5x #of cores on server machine
Client MapGuide Linux (all versions)
MapGuide 2.2 Windows
