Re: 4D Remote hanging at 3am after upgrading to Hi Sierra. Need logging advice.

2017-11-11 Thread Keisuke Miyako via 4D_Tech
The thinking behind this recommendation, as I understand it, goes like this:

macOS has its own cache system.
backup creates a large file.
the system cache the large file to improve access speed the next time (which 
typically never happens, by the way).
free system memory runs out.
4D Server asks for some memory.
the system does all sorts of things (compression, paging, whatever) to "create" 
free memory. this takes time.
4D Server is waiting.
4D Client disconnects.

"purge" (which is not installed by default and requires sudo) is a developer 
tool that forced the system to let go of cached files.

so to answer your question, the backup database method does run on the server, 
not client,
but that does not mean that it has no effect on the performance of connected 
clients.

Do the backup database methods run on connected clients (4D Remote) as well as 
on the server?

Brad said the client is disconnecting or hanging when the server runs backup. 
Even if the server could run purge after finishing the backup, how would that 
help the remote client which had its connection interrupted?

Is this a Mac?

If so, have you tried running a PURGE from the OS in On Backup Shutdown?

Re: Gridline for header in Listbox

2017-11-11 Thread Alan Chan via 4D_Tech
I agree with your taste:-) In fact, we originally used alternate color that 
looks really good and I love it. This is the case in "most" scenario except 
those contains so many columns and rows in a limited sized LB. This would make 
it so cramped.
Finally, we have 2 desgins - one with alternate color for LB with only few 
columns or the LB could be spared with more space on screen, mostly in 
accounting module. The rest stay with non-alternate-color approach.

The conclusion are result of votes from our engineers and a few of our major 
clients. Afterall, we are company of democracy . except on pricing:-)

 Any idea how to set horizontal gridline only for header but not 
 rows in Listbox in 4D 15.5?
 
 On Mac, there’s horizontal line for header automatically which 
 looks good. However, on Windows 10, no line for header which looks 
 odd...
