Specifying New Limits
your transaction throughput and response time requirements and to update or expand
the system to provide needed resources.
In response to your changing application requirements, you might need to specify new
limits or add, alter, or delete objects running under the Pathway/iTS product.
For example, as your system grows, you might need to add TERM objects to a specific
TCP to support availability of a RUN PROGRAM command, add another TCP, or add
an external TCP to ease the workload of the PATHMON process.
To specify changes for objects running under TS/MP, or to perform other system
reconfiguration tasks such as shutting down the PATHMON process, changing backup
CPUs, or changing security attributes, see the TS/MP System Management Manual.
All online configuration changes (ADD, ALTER, and DELETE commands) are saved in
the PATHMON configuration file. Because the ADD, ALTER, and DELETE commands
operate upon the PATHMON configuration file, these commands make obsolete any
previously established command file used to restart your PATHMON environment.
Specifying New Limits
You can increase or decrease limits for your overall environment using the SET
PATHWAY command. For example, the following command specifies a new limit for
the MAXTCPS parameters:
= SET PATHWAY MAXTCPS 40
You cannot specify new global limits while PATHMON-controlled objects are running;
you must first shut down the entire configuration.
For information about shutting down and starting your configuration, see the TS/MP
System Management Manual.
Adding, Altering, and Deleting Objects
The following subsections describe how to add, alter, and delete objects.
Certain commands that modify an object can be performed only if the object is not
running. For example, you can only delete an object that is stopped. So, before you
modify an object, you should be aware of its state: stopped, suspended, running, or
running but subject to a pending stop request. To determine the state of an object, use
the STATUS command for that particular object, as described earlier in this section.
Note. When specifying limits, you should always allow space for system growth. If you specify
sufficient limits initially, you can avoid the need to reconfigure and cold start your system to
specify new limits.
