To create a super user in UNIX/LINUX
Or
To change a Normal user to super user in UNIX/LINUX
- Create a new user (Or select a exists user)
- Set id 0 in selected user attributes through /etc/passwd file like-
(Before Edit ) asharma:*:128:20::/home/asharma:/sbin/sh
(After Edit) asharma:*:0:20::/home/asharma:/sbin/sh
3. Save file and exit.
Now your selected user works as root user.

An nPar is a Node Partition, sometimes referred to as a Hard Partition. An nPar can be considered as a complete hardware and software solution that we would normally consider as an HP server. When we think about the basic hardware components in an HP server, we commonly think about the following:
ReplyDeleteAt least one CPU,Memory,IO capability,An external interface to manage and configure the server, i.e., a system console,An operating system
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++A Virtual Partition (vPar) is an independent instance of an Operating System running on a subset of hardware components taken from an existing server or Node Partition. Each Operating System instance runs completely independently of other instances, and as such, a primary reason for using vPars is to offer application and Operating System software fault isolation. Additional benefits include:
Increased system utilization by partitioning previously unused portions of the server. Typically, a non-vPars server is only using 50 percent of its capacity.
Greater flexibility of resources through:
- Multiple but independent operating environments per server (with as low as one CPU granularity per partition)
- The dynamic movement of CPU power between virtual partitions depending on workload requirements.
Increased isolation of applications, their operating systems, and assigned resources (CPU, memory, and I/O) with individual reconfiguration and rebooting of the individual partitions without affecting other partitions and their applications.
Increased product integration with other HP-UX offerings that includes iCOD, Partition Manager, Online Diagnostics, and Virtual Partition Manager.
