Cautionary notes on installing DataMagic in a cluster environment

In a cluster environment, you must specify the installation folder on the local disk, and also specify the shared data storage folder on the shared disk.

Figure 1.3 Installing DataMagic in a cluster environment

When performing a new installation in a cluster environment, carry out the following steps to prevent the shared data storage folder on the shared disk from being replaced.

1. Install the software on the active node.

2. Configure the shared data storage folder of the standby node on the local disk, and then install DataMagic on the standby node.

3. After installation is complete, open installation-folder\huledpro.ini by using an editor, specify the path of the shared data storage folder on the shared disk as the HULEDPROPATH value, and then save the file.

[PATH]
HULEDPROPATH=path-of-the-shared-data-storage-folder-on-the-shared-disk

For an update installation, perform an update installation of DataMagic on the active node. Next, configure the standby node the shared data storage folder on the local disk, and then perform an update installation of DataMagic on the standby node. After installation is complete, modify the PATH description in huledpro.ini as specified in step 3.
