GBase Database Commercial Installation: A Step-by-Step Guide to License Loading

Installing a commercial edition of the GBase Database requires careful preparation and coordination of several steps to ensure a successful deployment. The first step is to request the commercial License, which may require providing the ESN and SSH private key of the GCware node associated with the target release. It's important to note that applying for the License too late can delay the project, and if any changes occur to the node or key during deployment, the License may need to be reissued.

The License file should be stored in a secure location, such as /opt, and accessible to the installation user without exposing it to unauthorized users.

Before beginning the installation, it's crucial to check the compatibility of the system with the GBase Database release. This includes verifying the CPU architecture, operating system, and Python runtime. The processor architecture can vary among Intel, Hygon, Zhaoxin, Kunpeng, Phytium, Loongson, and Sunway platforms, each requiring different packages.

The operating system and kernel environment must also be compatible, with certain distributions using specific package families. Lastly, the Python interpreter depends on the installer and commercial package edition, with different requirements for the FREE edition and commercial builds.

Once compatibility has been confirmed, the installation package should be extracted to the /opt directory using the installation account and directory permissions required by the deployment procedure. After extraction, the environment preparation script provided with the package should be run, if applicable. This script sets up the necessary environment variables and configurations, such as the database administrator user, installation prefix, and other relevant settings.

Before proceeding with the commercial installation, the License file must be loaded. This is typically done using the --license_file option followed by the path to the License file, as shown in the example command. It's essential to verify the exact command syntax and License loading behavior in the manual for the specific GBase Database release. Loading the License during installation is a critical step, as it ensures the software is properly authorized and ready for production use.

After the installation is complete, it's essential to verify the services, License status, and cluster state. This can be done by executing the relevant profile and service-management commands, such as source ~/.gbase_profile gcwa. By following these steps and verifying each stage of the process, organizations can successfully deploy a GBase Database commercial installation while minimizing the risk of deployment delays and issues.
