Workflow:
If
any of your workflow systems become unstable because of a problem
with one or more clusters in an environment, you receive a notification
directly in the cloud portal. You can then check the status of all
the clusters in each of the environments from the System
operations view.
Before you begin
To view that status of your environments and to receive status
notifications, you must have the Operator role.
About this task
The overall status of the workflow system is determined by
the status of each of its cluster members. The environments and each
of the clusters can have the following statuses:
Table 1. Statuses
of servers and clusters
| Status |
Description |
| Running |
All the clusters and their members are running
normally. |
| Partial |
Some cluster members aren't running normally.
Your workflow system is still operational, but you should check its
status to determine which clusters are affected. |
| Stopped |
One or more clusters are stopped. Check to see
which clusters aren't running and try restarting the clusters with
issues. |
| Unknown |
The status of the workflow system cannot be
determined, for example, because the node agent isn't running. Try
restarting the workflow environment. If the status doesn't change
after the restart, contact IBM® Support. |
To receive notifications outside of the cloud portal, you
can use the Cluster Status REST
API to build a status checking application that can push notifications,
for example, to Slack or to email. For more information about the
API, see the Cloud Pak for Business
Automation as a Service instance
services APIs in the API reference section.
Procedure
To check the status of the clusters in an environment,
complete the following steps:
- Log in to your cloud subscription.
-
Navigate to the System operations view of the environment you want to
work with.
- Select the environment you want to work with in the drop down menu and Click System
operations.
-
Check the status of the clusters in the environment with the issues by clicking
Server Status and Recovery.
- Get further insights into cluster issues by using the Log
Retrieval option to download a log for the associated
cluster.
Depending on which cluster has issues, you might
be able to resolve the problem by taking the following actions:
- Application cluster (AppCluster)
- If you determine that the problem might be caused by one or more
process applications, you can use the Process Admin Console to investigate
the problem further and take remedial action. For more information,
see Process Admin Console. If the problem is with
an enterprise application, such as a BPEL process, try using Business
Process Choreographer Explorer to investigate and fix the issue. For
more information, see Business Process Choreographer Explorer.
- Support cluster (SupCluster) or Messaging cluster (MECluster)
- The problem might be due to an infrastructure problem. Try restarting
the cluster, which has the issues.
- If restarting individual clusters doesn't resolve the problem,
try restarting the entire workflow environment.
The
restart procedure stops and starts all workflow servers and clusters
in the environment. The progress of the restart is shown and depending
on your workflow system, it might take several minutes to complete.
When all your workflow systems are running normally again,
you'll receive the corresponding notification in the cloud portal.
If the problem persists after the restart, contact IBM Support.
