command primarily display details users logged system transactions

Which command is primarily used to display the details of users who are currently logged into a system and their transactions?

No

The internal ID number of a process. Used to identify messages that belong to a work process in the system log

Type

Type of work process:

  • DIA Work process for executing dialog steps in user transactions

  • UPD Update process for making V1 (time-critical) database changes

  • UP2 Update process for executing V2 (not time-critical) database changes

  • ENQ For locking or releasing SAP lock objects

  • BTC For processing background jobs

  • SPO For spool formatting processes

PID

Process ID of the work process (on the operating system)

Status

Current status of the work process. Possible statuses are:

  • Running (executing a request)

  • Waiting (idle and waiting for a request)

  • Hold (held for one user) is not an abnormal state, but a work process can only serve a single user.

    If too many processes are in Hold , then system performance suffers. You can then use the Reason field to identify holds that perhaps can be released.

  • Stopped (aborted; Restart set to No).

  • Shutdown : Process terminated because of a shutdown

    For more information, see SAP Application Server States

  • Reserved : Process is reserved

    For more information, see Dynamic Work Processes

Reason

If a work process is in hold status, the reason is displayed. Typical reasons include the following: Debugging, CPIC activity, locks, updates, GUI (system waits for response from the SAPGUI front-end program, for example, for a remote function call (RFC)). For an overview of the possible parameters, refer to the F1 help.

You may also see PRIV (PRIVate use) as a reason for holding a work process. PRIV indicates that a work process is reserved for a single user for memory management use. The work process has exceeded the limit of the SAP memory that is used by other processes. The process is held as long as the current user requires local memory. For more information, see Private Memory in the documentation on SAP Memory Management.

If more than a certain percentage of work processes are in PRIV hold state, then PRIV transactions are automatically terminated if the user is not active in the transaction for a set period of time. You can set this timespan in the SAP system profile.

Start/Restart

Indicates whether the process should be automatically restarted if a process ends prematurely. You can change the restart status of a process by choosing . Normally, leave Restart set to Yes .

If a work process aborts during its startup, the system automatically sets Restart to No . This measure protects against endless attempts to restart a process if a database system is not available or another serious problem is affecting the system. After correcting the problem, you can change Restart to Yes so that the system starts the work processes.

Err

Indicates how many times a work process has aborted since the instance was started. You can also reset the counter.

For more information, see Edit Process (menu option: List)

Stored Semaphore

Specifies the number of the semaphore held by the work process. If the process is holding several semaphores, the numbers are separated by inverted commas. F1 help provides a list of all semaphores used by SAP.

Curr. Sem.

Indicates the number of the semaphore for which a work process is waiting. Normally, this field should be empty. If it occurs again after refresh, you can see in the Locked Sem. column whether the required semaphore is being held by another work process. F1 help provides a list of all semaphores used by SAP.

CPU

Cumulative CPU time used by a work process since it was started. The time units are seconds and hundredths of seconds.

Note

Calculating CPU time is onerous. For this reason you have to request this information directly. Choose or

.

Time

Indicates the elapsed time used by a work process for the dialog step that it is currently being processed

Report

ABAP program or report that is currently being executed

Clie:

Client for the session that is currently being executed

User

User whose request is currently being processed

Action

Action that is being performed by the program that is running. The actions that are displayed are those that are recorded by the SAP performance monitor. The performance monitor must be active (SAP profile parameter stat/level = 1 (default)) for actions or database table accesses to be displayed.

Table

If the database is being accessed, this column contains the name of the table that is being accessed.

Which command is used to create a user account and configure basic settings?

To create a new user account, invoke the useradd command followed by the name of the user. When executed without any option, useradd creates a new user account using the default settings specified in the /etc/default/useradd file.

Which command enables a user to log in to a system with their own credentials, and then become the root user to perform administrative tasks? su-The su command enables an authorized user to become the root user.

What file does the last command retrieve information from?

The last command displays information about the last logged-in users. It's pretty convenient and handy when we need to track login activities or investigate a possible security breach. The last command will, by default, take the system log file /var/log/wtmp as the data source to generate reports.

What is used to specify a group ID?

-g, –gid GID : This option is used to provide a group id (numeric) to the new group, and it should be non-negative and unique unless explicitly created to be non-unique (using -o option). If this option is not used, the default id is assigned, which is greater than every other group already present.
