[mapguide-users] Shape Layer Issue

[liglio.pessoal at nexxa.com.br]

Hi Jackie,

 

I receive several read only shapes files in a timely way (5 minutes), and my app has a timer (10 seconds) that continually is showing those files at 5 minutes range, but very often there is no file to show. So, it causes a FDO error. I also notice an continually increase of mapguide server memory usage, maybe because of this error. 

I must keep this layer visible to appear in my custom layer control  of visibility (or maybe there is another way to do it?).

 

 

Regards,

 

  Liglio

Hi Liglio,

 

Are you continually updating the shape files underneath or doing any other concurrent read/write access to these files?

 

If so, then you should reconsider the use of SHP files for this kind of scenario and loading the data into a relational database, which is designed for such multi-user concurrent access.

Hi, 

 

I have a shape layer that I programatically point to shape files using the
feature source, continually in a timer. But sometimes there is not a file to show, and the layer must have the
attribute visible = true.

 

When this occurs I got an error in the log file ("The specified class was
not found."). There is something I can do to avoid this error ?

 

Regards,

 

Liglio
