Distributed command line utility(dcli) provides an option to execute the monitoring and administration commands on multiple servers simultaneously.In exadata database machine , you may need to create the griddisks on all the exadata storage cells frequently. Each time , you need to login to all the storage cells and create the griddisk manually.But dcli will make […]
Exadata Storage Cell – Administrating the Disks – Part 5
Exadata Storage server uses the cell software to manage the disks. Like volume manager, we need to build couple of virtual layers to get the grid disks.These griddisk will be used to create the ASM disk group on the database level . In this article, we will see that how we can create/delete the celldisk, […]
Exadata – CELLCLI command Line Utility1 – Part 4
Exadata storage is managed by CELLCLI command line utility. Management process (MS) will communicate with cellcli to maintain the configuration on the system. CELLCLI utility can be launched by user “celladmin” or “root”. In this article ,we will see how to list the storage objects and how to stop/start the cell services using the CELLCLI […]
Exploring the Exadata Storage Cell Processes – Part 3
Exadata storage cell is new to the industry and only oracle is offering such a customized storage for oracle database. Unlike the traditional SAN storage ,Exadata data storage will help to reduce the processing at the DB node level. Since the exadata storage cell has its own processors and 64GB physical memory , it can […]
Architecture of Exadata Database Machine – Part 2
Exadata Database machine provides a high performance,high availability and plenty of storage space platform for oracle database .The high availability clustering is is provided by Oracle RAC and ASM will be responsible for storage mirroring .Infiniband technology provides high bandwidth and low latency cluster interconnect and storage networking. The powerful compute nodes joins in the RAC […]
