Novell NetWare 6.5 Support Pack 7
Novell iManager 2.7
Novell ZENworks 7 Server Management Support Pack 1 - ZSM7 SP1
Tiered Electronic Distribution (TED)
In a large ZSM environment with many distributions, it is
possible for the Subscriber Distribution View within iManager to
timeout after 5 minutes with a 503 error. The only course of
action is to exit iManager.
1) Modify the SYS:\ADMINSRV\CONF\MOD_JK\WORKER.PROPERTIES
2) Go to the "DEFAULT ajp13 TOMCAT 5 WORKER DEFINITION"
3) Modify the worker.ajp13tc5.reply_timeout value and set it
property told web server to wait some time for reply to a forwarded
request before considering the remote tomcat is dead and eventually
switch to another tomcat in a cluster group.
By default on NetWare the web server will wait 180000
milliseconds. The parameter is the number of milliseconds to wait
for reply. By setting it to 0 it allows for an indefinite
wait. This allows tomcat to keep speaking with Apache while
it waits for the XML parsing to finish on the
distributor. To further explain the Subscriber Distribution
Process see below.
1. For each subscriber the iManager plug-in
makes an edirectory call to get the information about channels and
for each channel get the distributions, and for eachdistribution get the distributor object. All these
are read and kept.
2. Get all distribution objects for eachdistributor (through xmlrpc process in the form of XML) from
distributor. Here a request is made to the distributor to return
all the distributions that a subscriber has.
3. For each distribution in the channel get
the status of the distribution through xmlrpc or XML format
from the distributor. The distributor will read thedistributionTracking.ted& extractionTracking.ted
to get information about the distribution and extraction
status, form the XML data and return it to the iManager
4. Step 3 is repeated for each distribution that a
subscriber has. If multiple subscribers were picked as part
of the subscriber distribution view it parses thedistributionTracking.ted&extractionTracking.ted files once looking for all
5. Once all status xml's are returned to iManager,
they are processed and status is displayed on the SDV
This process can be seen by setting the log level in iManager
to Errors, Warnings and Debug Information messages and watching the
Logger Screen on the server.
