Oracle Linux Virtualization Manager (OLVM) is a powerful virtualization platform based on oVirt. Ensuring consistent backups of the OLVM environment is critical for disaster recovery and business continuity. The backup process primarily includes the engine database, configuration files, and optionally VM disk images (data domains).  Backup the OLVM Engine Database:  Use the engine-backup utility to back up the manager database and configuration. engine-backup --mode=backup \ --file=/backup/olvm_engine_backup.tar \ --log=/backup/olvm_backup.log \ --scope=all --scope=all ensures both the engine DB and configuration files are included.  Backup should be run on the OLVM manager node. Backup Data Domains (VM disks):  Use storage-level tools or snapshot methods to back up virtual machine disks.  For iSCSI/NFS domains:  Use storage-side snapshots or backup tools like rsync or tar. For GlusterFS:  Use Gluster snapshots or native backup solutions....

Oracle Solaris and IBM AIX are both enterprise-grade Unix operating systems that have long histories in mission-critical environments. However, their future is increasingly uncertain as the IT industry shifts toward cloud-native, Linux-based, and containerized solutions. Oracle Solaris has seen limited development in recent years, with Oracle focusing more on its cloud offerings, leading many to question its long-term viability. Similarly, IBM AIX, while still actively supported, is increasingly viewed as a legacy system as IBM emphasizes Linux, particularly Red Hat Enterprise Linux, for modernization and hybrid cloud strategies. Despite continued use in sectors like finance and government, where stability and long-term support are crucial, both Solaris and AIX face declining adoption and a shrinking talent pool, suggesting that their roles in enterprise IT will continue to diminish in the coming years. Migrating an Oracle E-Business Suite (EBS) database from Solaris to Linux involves ...

Introduction to Oracle KVM Cluster Oracle KVM Cluster is an enterprise-grade virtualization solution that leverages the Kernel-based Virtual Machine (KVM) hypervisor, integrated within Oracle Linux. It enables the creation and management of clustered virtual environments, providing high availability, scalability, and centralized management for virtual machines across multiple physical hosts. By combining the performance and efficiency of KVM with Oracle's robust clustering and management tools—such as Oracle Linux Virtualization Manager (OLVM) and Oracle Clusterware—Oracle KVM Cluster supports mission-critical workloads with features like live migration, fault tolerance, and resource pooling. This makes it an ideal platform for consolidating workloads, optimizing resource utilization, and ensuring business continuity in modern data centers.   In this blogpost we will see how we can configure the KVM cluster using the command Line options: Creating an Oracle KVM cluster from...
