D.2 Daemon process status transitions

If SSO cannot link with NNMi, the process status transitions change according to whether the daemon process stops temporarily (SUSPENDING) or continues to operate in reduced mode (DEGENERATING).

The behavior that the daemon process adopts when NNMi linkage is impossible is defined by using the nnm-coop-policy key in the ssospmd action definition file (ssospmd.def). For details about the ssospmd action definition file, see 6.3.25 ssospmd action definition file (ssospmd.def).

Organization of this subsection

(1) Status transitions in the case where the daemon process stops temporarily
(2) Status transitions in the case where the daemon process operates in reduced mode

(1) Status transitions in the case where the daemon process stops temporarily

The figure below shows the status transitions in the case where the daemon process stops temporarily when NNMi linkage is impossible. The numbers in the figure correspond to the item numbers of the table that follows the figure.

6	The daemon process stopped temporarily because inability to link with NNMi was detected.^#2	RUNNING `->`SUSPENDING* `->`SUSPENDING

13	The daemon process was started when backup processing terminated.	RUNNING* `->`RUNNING
14	The daemon process could not be started when backup processing terminated.	RUNNING* `->`NOT_RUNNING
15	SSO became unable to link with NNMi when backup or deletion processing of a collection database was in progress.^#1	RUNNING `->`SUSPENDING*
16	Backup or deletion processing of a collection database ended when NNMi linkage was impossible.^#2	SUSPENDING* `->`SUSPENDING
17	SSO became unable to link with NNMi when the daemon process was being started.^#3	RUNNING* `->`SUSPENDING* `->`SUSPENDING
18	SSO became unable to link with NNMi when the daemon process was being restarted.^#3	RUNNING* `->`SUSPENDING* `->`SUSPENDING

#1: This description is not applicable to the ssoconsoled and ssotrapd daemon processes.

#2: When the daemon process stops temporarily, a status change incident is not sent to NNMi because NNMi linkage is impossible.

#3: This description is applicable to the ssoapmon and ssocolmng daemon processes only.

(2) Status transitions in the case where the daemon process operates in reduced mode

The figure below shows the status transitions in the case where the daemon process operates in reduced mode when NNMi linkage is impossible. The numbers in the figure correspond to the item numbers of the table that follows the figure.

No.	Description	Transition
1	The daemon process was started when NNMi linkage was possible.	NOT_RUNNING `->`RUNNING* `->`RUNNING
2	The daemon process was stopped.	RUNNING `->`NOT_RUNNING* `->`NOT_RUNNING
3	Backup started.^#	RUNNING `->`PAUSING* `->`PAUSING
4	Backup processing ended when SSO could link with NNMi.	PAUSING `->`RUNNING* `->`RUNNING
5	The daemon process was started when NNMi linkage was impossible.	NOT_RUNNING `->`DEGENERATING* `->`DEGENERATING
6	The daemon process entered reduced mode because the inability to link with NNMi was detected.^#	RUNNING `->`DEGENERATING* `->`DEGENERATING
7	The daemon process restarted normal operation because the ability to link with NNMi was detected.	DEGENERATING `->`RUNNING* `->`RUNNING
8	Backup processing ended when NNMi linkage was impossible.	PAUSING `->`DEGENERATING* `->`DEGENERATING
9	The daemon process was stopped.	DEGENERATING `->`NOT_RUNNING* `->`NOT_RUNNING
10	The daemon process could not be started.	DEGENERATING `->`RUNNING* `->`NOT_RUNNING
11	The daemon process was stopped.	PAUSING `->`NOT_RUNNING* `->`NOT_RUNNING
12	The daemon process was interrupted to perform backup processing.	DEGENERATING `->`PAUSING* `->`PAUSING
