HCL Workload Automation, Version 9.4

Example 10: Upgrading agents in a cluster-aware configuration

About this task

Upgrade agents in a cluster-aware configuration as follows:

Set all the nodes of the cluster to the Pause state. Perform this action by running the following command against each node:
```
cluster.exe node NODE1 /Pause
```
Set offline all the HCL Workload Automation resources belonging to the nodes of the cluster you paused:
```
cluster.exe res RES1 /Offline
```
For all the nodes in the cluster, upgrade all the resources running on the nodes, by performing the following steps:
1. Generate the installation registries for one of the cluster groups belonging to the node on which you are upgrading the resources, and upgrade the instance you are working on, using the following script:
```
cscript.exe twsinst.vbs -update -uname user1 
-password password1
 -inst_dir "C:\Program Files\HCL\TWA" -recovInstReg true
```
2. Update the remote Windows Services and the resource DLL, by running the following command:
```
twsClusterAdm.exe -update resource=RES1 ask=yes -twsupd pwd us1pass1
```
3. Repeat steps 3.a and 3.b for all the resources present on this node.
Resume all the nodes of the cluster you paused in step 1 by running the following command against each node:
```
cluster.exe node NODE1 /Resume 
```
Bring online the HCL Workload Automation resources on all the nodes, by running the following command against each resource:
```
cluster.exe res RES1 /Online 
```
