Server
This command is optional.Linkdepth max-number
specifies the maximum number of concurrent links that a specific LINKMON
process can have to any server process in the class defined by this Server
directive. A LINKMON process manages the links for all requesters in the same
CPU as the LINKMON process.
The value of Linkdepth should not exceed the value of Maxlinks and cannot
exceed 255.
If you omit this command, the default is 1.
Typically, you use the Linkdepth command to allow multithreaded servers;
for servers that are not multithreaded, use the default value of 1 for
Linkdepth.
The following Linkdepth command would allow two concurrent requests
from each LINKMON process to any server in the server class:
Linkdepth 2
MapDefine define-name OSS-path
allows a server to be propagated with a define set.
An example of the MapDefine command is as follows:
MapDefine =TCPIP^PROCESS^NAME /G/ztc0
MapDefine =abc /G/system/sql
where the first token is a legal define name and the second token is the OSS
form of a Guardian file name.
This command is optional.
Maxlinks max-number
specifies the maximum number of concurrent links permitted between all
LINKMON processes—therefore, between requesters in all CPUs—and a server
process in the class defined by this Server directive.
max-number must be a value from 1 through 4096. This command establishes
the maximum number of concurrent send operations to a single server process.
A LINKMON process does not check how many links a server has with other
LINKMON processes.
If the value for this attribute is too large, the requests to the server process are
queued at the server. For example, if Maxlinks is equal to 20, there could be
20 concurrent requests outstanding to a server. If the transaction service time is
1 second, a response time of more than 20 seconds can occur.
Note. In order to achieve the load-balancing enhancement described in iTP Secure
WebServer httpd on page 1-8, the Linkdepth command value must be set to 1 (the
default value) for the httpd configuration.
