The xml files are processed with the XMAPReadNext command using a mapping file
that is defined in &XML&. Basically the "Batch API" does:
FOR X.JOB = 1 TO NB.JOB
XML.PARAM = JOB<X.JOB>
Parse XML.PARAM in a DYN.ARRAY (using map in &XML&)
CALL @JOB.NAME(DYN.ARRAY,OUT.ARRAY)
Build XML.OUT string from OUT.ARRAY
Store XML.OUT in JOB.OUT<X.JOB>
NEXT X.JOB
Return JOB.OUT to the calling web service
I will try upgrading the Uniobjects dll to see what it does.
Thanks

Another thing to try is process the xml files outside of uniobjects but
still in databasic and see how it goes. If it uses large amounts of memory
then it is not a uniobjects issue . You could then try using those xml files
from a *nix shell program like xmlwf / xml_pp or xsltproc. These use the
standard xmllib library that uv may be using so if those give high memory
usage it may not even be a uv issue but a *nix library issue.

That triggered a memory. If you are using an older version of uniobjects in
the .Net you can get memory issues when you upgrade the database. Have a
look at upgrading the uniobject .Net to the lastest release.

On unidata I have had to process many an xml file outside of the DB as the
memory just shoots right up
If you are using uniobjects then I presume you have .net or java at the
front end and it is likely that these environments are better suited to
'handling' the xml and simply passing data arrays to the universe layer to
work on.

Hello,
In order to save connection time on Uniobjects API requests, I came up with
an Api which could contain several XML requests into one, Process each one
in the requested order and return the answer of each request in the
resulting XML request.
On Universe 10.2.11, the API runs anywhere from 10 to 50 requests in a
batch like this taking no more than between 45 and 59 megs of ram on a HP-UX
server.
Starting with Universe 11.1.3, doing far fewer requests (ei from 5 to 9)
the memory requirements go up as high as 100 to 122 megs of Ram on a HP-UX.
Somewhere it looks like Universe's XML generation routines are gobbling up
memory and this memory is not getting freed. It seems that many memory
leaks were fixed from 10.2.1 to 11.1.3 according to the release notes but a
huge new one was introduced.
I know of the memory used by the process because I have a job which produce
the output of the "top" command once a minute, so the memory used by a
process extracted from the output of the top command and logged.
Has anyone else experienced anything like this ?
Jacques G.
