Determining the HULFT installation environment
Determine the HULFT installation environment to operate HULFT in a bidirectional standby configuration.
In this case, two instances of HULFT can operate in a single node.
Install HULFT in both environment A and environment B. Here, we assume that environment A and environment B perform processing A and processing B, respectively.
In this case, each environment requires the following resources.
-
Virtual IP address
-
Virtual host name
-
Disk (that allows you to specify other logical partitions)
In addition, to operate HULFT independently in each environment, specify different settings for the following fields between the two environments.
-
Execution module storage directory (HULEXEP)
-
Environment settings file storage directory (HULPATH)
-
Pid File Generation Path
-
Receive Port No.
-
Observe Port No.
