The "chadmin" command can be used to modify the attributes of a user account, including the groups that the user belongs to. The syntax for limiting root user access to members of the group called "system" would be:

sql

chadmin group=system root

This command will add the root user to the "system" group and remove it from any other groups. Members of the "system" group will be the only ones able to access the root account.

The niminit command can be used to rebuild the /etc/niminfo file on an AIX NIM client system if it has been accidentally deleted. This command will read the NIM database on the NIM master and generate the /etc/niminfo file accordingly. Reference: IBM AIX v7 Administrator Specialty Study Guide.

The root account is the special user in the /etc/passwd file with the user ID (UID) of 0 and is commonly given the user name, root. It is not the user name that makes the root account so special, but the UID value of 0. This means that any user that has a UID of 0 also has the same privileges as the root user. Also, the root account is always authenticated by means of the local security files.

The istat command displays information about the inode of a file, including the last access time. This command is available on IBM AIX v7 systems and is documented in the IBM AIX v7 Administrator Specialty Study Guide. The syntax for the command is "istat file", where 'file' is the path to the file you would like to check. For more information, please see the IBM documentation at 

When a customer calls with a complaint about slow workload performance, it is important to ask for additional details to help pinpoint the source of the issue. This could include details such as which application or process is running slowly, what errors are appearing, how long the issue has been occurring, etc. Having this information will help the administrator to determine the cause of the problem and determine the best course of action. Reference: IBM AIX v7 Administrator Specialty Study Guide (page 5-29).

A mksysb image is a snapshot of the AIX operating system and its configuration, so it can be used to boot the server and perform the required maintenance tasks. However, in order to use the mksysb image, the administrator may need to create a machine resource in the NIM environment first. According to the IBM AIX v7 Administrator Specialty Study Guide (page 13-6), the mksysb image should be used in combination with a previously created machine resource, which defines the parameters for the installation.
