Automatically Monitoring and Restarting NPAC Agent Processes

The following sections describe the failure conditions for which sentryd monitors the regional NPAC agent processes (npacagents) and the steps performed in attempts to restart an npacagent process after failure has been detected.

Monitoring NPAC Agent Processes

For each region, sentryd monitors its npacagent process for the following conditions:

Failure to initialize during automatic system startup
Failure to initialize during manual startup using the lsms command
An unintentional exit or crash during normal operation
Inability to perform its defined tasks, for example, because it is in an infinite loop

Restarting NPAC Agent Processes

When one of conditions described in “Monitoring NPAC Agent Processes” has been detected, sentryd performs the following tasks:

Generates the following surveillance notification:
```
LSMS6008|08:40 Sep 11, 1998|xxxxxxx| Notify:Sys Admin - FAILED:
<NPAC_region> agent
```
where <NPAC_region> indicates the name of the region whose npacagent process has failed.
Attempts to stop and restart the failed npacagent. If the npacagent restarts, sentryd generates the following Surveillance notification:
```
LSMS6009|08:40 Sep 11, 1998|xxxxxxx| Notify:Sys Admin - RECOV:
<NPAC_region> agent
```

Continuing Attempts to Restart NPAC Agent Processes

If the attempt to restart the npacagent fails, sentryd attempts again. If this attempt is also unsuccessful, the sentryd process generates the following Surveillance notification and continues to attempt to restart the npacagent process.

LSMS6010|08:40 Sep 11, 1998|xxxxxxx|Notify:Sys Admin - RFAILED:
<region> agent

If this notification appears several times in a row, contact the My Oracle Support (MOS).
