uCosminexus Application Server, Maintenance and Migration Guide
The method for restarting the system, when Application Server configuration software process terminates abnormally, is described here.
In a system build on Application Server, if the start order is set up when the component software process (logical server) of Application Server terminates abnormally, the Management Server will automatically restart the component software. In the Management Server, the processing of component software is managed as Logical Server.
When restarting manually, if the abnormally terminated configuration software has startup dependencies, confirm that the configuration software, on which the abnormally terminated configuration software depends for starting, is running. The configuration software, on which the abnormally terminated configuration software depends, varies depending on the configuration of the system. The startup dependencies of the configuration software and the method of restarting the configuration software are explained below:
The startup dependencies of the configuration software process configuring a system built with Application Server are explained here.
Hereafter, the configuration software process startup dependencies are explained for each J2EE server operation mode:
The dependencies of the process are as follows:
Table 2-8 Dependencyof processes
Process type | Dependant process |
---|---|
Performance tracer | -- |
Smart Agent#1, #2 | -- |
CTM domain manager#1 | Smart Agent#1, #2 |
CORBA naming service | -- |
CTM daemon#1 |
|
SFO server |
|
J2EE server |
|
Web server | Performance tracer |
The restart method of a process when the process terminates abnormally in a system is as follows.
The procedure of process restart (recovery) is as follows:
Table 2-9 Procedureto restart (recovery) processes
Abnormal process | Start command | Restart (recovery) procedure |
---|---|---|
Database server | -- | Restart the DB server. |
OpenTP1 | -- | Restart the OpenTP1. |
Performance tracer | cprfstart | Restart the performance tracer. |
Smart Agent#1, #2 | Osagent | Restart the Smart Agent. |
CTM domain manager#1 | ctmdmstart | Restart the CTM domain manager. |
CORBA naming service | Nameserv | Perform actions based on the procedure shown below. Furthermore, when CTM is not used, procedure 1 and 4 are not required.
|
CTM daemon#1 | ctmstart | Perform actions based on the procedure shown below.
|
CTM regulator | -- | Since restarted automatically by CTM daemon, restart is not required. |
SFO server#3 | cjstartsv | Restart the SFO server. |
J2EE server | cjstartsv | Restart the J2EE server. |
Web server | -- | Restart the Web server. |
