db_log_buffer_full error

[nick_xu]

Our map has more than 400 layers, and I see this errors very often from error log file:

Error: An exception occurred in DB component.
Db:ut: DB_LOG_BUFFER_FULL: In-memory log buffer is full      

Is anyway to set DB_LOG_BUFFER.

we use AIMS 2012

Autodesk Infrastructure Map Server (Version 2.3.0.5801)
Autodesk Infrastructure Map Viewer (Version 2.3.0.5801)

I tried to reduce some layers and see less this error on log file.

Any solution?

thanks!

If you are using AIMS2013,  try changing (increase) the highlighted below -

[DBEnvironmentProperties]

# *****************************************************************************

# DB ENVIRONMENT

# This section is to set DB Environment. Determine the best sizes to improve the Server performance.

LibraryCacheSize                   = 32

SessionCacheSize                   = 2

DBPageSize                         = 32

DBXMLPageSize                      = 32

LibraryLogBufferSize               = 12

SessionLogBufferSize               = 1

DBMaxTransactions                  = 1000

SessionDBPageSize                  = 2

SessionDBXMLPageSize               = 0.5

DBTimeout                          = 0.2

DBMaxLockers                       = 1000

For AIMS 2012, you may need a upgrade, see this link : http://trac.osgeo.org/mapguide/ticket/1779
