Thread from where the method gets called warmStandbyModeUtil.getWarmStandbyMode()
public void executeJob(JobExecutionContext context) throws JobExecutionException {
ApplicationContext applicationContext = SpringSupport.getApplicationContext();
//No need to generate notifications from a standby server
if (warmStandbyModeUtil.getWarmStandbyMode() == WarmStandbyModeUtil.WarmStandByMode.ACTIVE
&& context != null) {
try {
NotificationService esmNotificationService = (NotificationService) applicationContext.getBean("notificationService");
esmNotificationService.processNotifications();
} catch (Exception e) {
LOGGER.error("Error occurred in notification dispatch job: " + e.getMessage());
}
}
}
The actual code where the issue is happening
public WarmStandByMode getWarmStandbyMode() {
String content = new String(Files.readAllBytes(Paths.get(nwNodeModeFile)));
}
