RE: Garbage characters received by socket

Bob,

Are you suggesting the receiver variable in the RPG program should be 65,535?  
When you mention feedback I don't know what we should look for.  Maybe that the 
'missing' XML will be later in the field?

The user space idea sounds good. 

Rick

Perhaps the coworker's field into which he is receiving the socket data is 
declared as a 32767A field. He can increase it to 65535A to get some immediate 
feedback to see if that's his problem.
Another idea is to create a user space, get a pointer to that users space, and 
pass the pointer to the user space to the recv() function.

If he's getting the data in packets/chunks and just filling up a 32k field with 
the data he's receiving (typically in a loop until recv() returns zero bytes), 
then he could, as suggested, declare a larger, 64k field for his "buffer".

There haven't been any takers on the midrange-l list so I'm cross posting here.

We have an application that monitors a socket for application information in an 
XML format.  At varying places in the transmission we receive a string of '@'.
The program parsing the XML will ignore them and viewing the received XML via a 
browser doesn't have any trouble.

The issue is that we sometimes don't receive the entire XML string.  A 
co-worker is responsible for this process and tells me that there is a 32k 
buffer restriction.  He thinks the '@' string sometimes pushes the data beyond 
the buffer size and we lose it.

We believe the information is being sent from a windows box.

Does this sound right?  Has anyone else encountered this type of behavior using 
sockets in the iSeries?
