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

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

7

The daemon process was started because ability to link with NNMi was detected (except when backup processing was in progress).

SUSPENDING

->RUNNING*

->RUNNING

8

The daemon process was stopped.

SUSPENDING

->NOT_RUNNING*

->NOT_RUNNING

9

An attempt was made to start the daemon process because ability to link with NNMi was detected, but the attempt did not succeed (except when backup processing was in progress).

SUSPENDING

->RUNNING*

->NOT_RUNNING

10

The daemon process could not be started.

NOT_RUNNING

->RUNNING*

->NOT_RUNNING

11

The daemon process was stopped.

PAUSING

->NOT_RUNNING*

->NOT_RUNNING

12

SSO is now waiting for the daemon process to start because ability to link with NNMi was detected during backup processing.

SUSPENDING

->RUNNING*

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.
