SRP (Startup and Recovery Process)

SRP (the Startup and Recovery Process) is the parent of all MPS software processes. It

is responsible for starting and stopping most other software processes, and for polling

them to ensure proper operation. It also restarts abnormally terminated programs.

One instance of SRP runs on each MPS node to control the systems associated with

that node. As SRP finishes starting on each node, an informational alarm message is

generated indicating that the system is running.

SRP has its own configuration file that provides for control of some internal functions.

For information about this file, see The srp.cfg File on page 89.

Each MPS node contains two classes of software processes, each of which has its own

set of configuration files processed by SRP:

• The VOS (Voice Operating Software) process group is comprised of the core

system software for running the MPS system (see VOS Processes on page

39).

• The ASE (Application Services Environment) process group is comprised of

software to execute call processing and administrative applications (see ASE

Processes on page 36).

In addition to controlling processes specific to each MPS system, SRP manages a

common MPS (i.e., virtual MPS), which is used to run processes requiring only one

instance per node. This includes system daemons, such as ALARMD.

Currently, the SRP is capable of starting pot approximately 300 applications.

Manually Starting and Stopping SRP

Normally, SRP is automatically started at boot time. If SRP has been stopped, it can

be manually restarted.

If it is necessary to control the starting and stopping of SRP, it is first necessary to

disable the operations of the S20vps.startup script. To do this, become root

user and place an empty file with the name novps in the $MPSHOME directory.

To manually start SRP on Solaris systems, execute the following command:

PeriWeb PERIpweb

Service Installation Package

/etc/rc3.d/S20vps.startup start

Starts the MPS system software. This command can be used to restart SRP.
