Introduction to Accounts, Groups, and Users
NOTE The MPE/iX operating system has been enhanced as of Release 4.5 and 5.0 to include additional features. For more information on these features, refer to the book, New Features of MPE/iX: Using the Hierarchical File System (32650-90351), included in this documentation set.
If you installed the software for your organization, you have already seen the terms accounts, groups, and users. If someone else showed you how to log on, you have used an account, group, and users perhaps without even knowing it. The account structure consists of four elements: * accounts * groups (who belong to accounts) * users (who belong to accounts) * files (who belong to groups) As a user, you are assigned to a specific account. When you log on, you enter HELLO, your user name, and the name of the account to which your user name is assigned. An account may have more than one user assigned to it. To understand the account structure, think of your computer system as a filing room in which there are many filing cabinets. Each separate cabinet in the room is comparable to a separate account on the computer system. Try the following exercises to help familiarize yourself with commands that give you information about your accounts, groups, and users. To list account information The LISTACCT command provides information about assigned capabilities, disk space limits, and user access. To display this information, enter: :LISTACCT Return A description of the account that you are logged on to appears: ________________________________________________________________________ | | | | | ******************** | | ACCOUNT: PRACTICE | | | | DISC SPACE: 16(SECTORS) PASSWORD: ** | | CPU TIME : 18(SECONDS) LOC ATTR: $00000000 | | CONNECT TIME: 333(MINUTES) SECURITY--READ : AC | | DISC LIMIT: UNLIMITED WRITE : AC | | CPU LIMIT : UNLIMITED APPEND : AC | | CONNECT LIMIT: UNLIMITED LOCK : AC | | MAX PRI : 150 EXECUTE : AC | | GRP UFID : $055A0002 $0D079125 $0024FFB6 $1E033861 $2C3362E2 | | USER UFID: $055A0001 $0D079125 $0025D4B6 $1E033861 $2C3362E9 | | CAP: AM,AL,GL,ND,SF,BA,IA | | | ________________________________________________________________________ The CAP information listed at the lower left and the SECURITY information listed in the right column give you the following information about this account. CAP stands for capability. The abbreviations that follow indicate the capabilities assigned to your account. You can find explanations for these abbreviations and those in the SECURITY column in Volume III of this guide. To list account passwords If you forget your account password while you are logged on to your account, you can list your password by using the LISTACCT command followed by the PASSWORD parameter. You must have account manager (AM) capability to list your account password with the LISTACCT command. Try this now: :LISTACCT;PASS Return To list group information Accounts can be divided into smaller units called groups. Groups are comparable to the drawers in each filing cabinet. Files reside in groups. A quick way to list the groups within an account is to use the REPORT command. Enter that command now to see which groups are currently in your account: :REPORT Return Here's a sample of what you might see on your screen: ________________________________________________________________________ | | | | | ACCOUNT FILESPACE-SECTORS CPU-SECONDS CONNECT-MINUTES | | /GROUP COUNT LIMIT COUNT LIMIT COUNT LIMIT | | PRACTICE 16 ** 18 ** 333 ** | | /PUB 16 ** 7 ** 252 ** | | /QTR1 0 ** 11 ** 81 ** | | | ________________________________________________________________________ The names of the account PRACTICE and its groups PUB and OTR1 are listed in the far left column. Additional columns of information state the amount of file space occupied by the account and its group, the cumulative total CPU time used by persons using that account and group, as well as their cumulative connect time to the system. To see detailed information about groups To get more detailed information about the groups in your account, use the LISTGROUP command. Enter: :LISTGROUP Return You should see a display similar to the following on your screen: ________________________________________________________________________ | | | | | GROUP: PUB.PRACTICE | | | | DISC SPACE: 44384(SECTORS) PASSWORD: ** | | CPU TIME : 17871(SECONDS) SECURITY--READ : ANY | | CONNECT TIME: 8373(MINUTES) WRITE : AL, GU | | DISC LIMIT: UNLIMITED APPEND: AL, GU | | CPU LIMIT : UNLIMITED LOCK : AL, GU | | CONNECT LIMIT: UNLIMITED EXECUTE : ANY | | PRIV VOL : NO SAVE : AL, GU | | FILE UFID: $055A0003 $0D079125 $000A77B4 $1A0300D6 | | MOUNT REF CNT: n/a | | HOME VOL SET : MPEXL_SYSTEM_VOLUME_SET | | CAP: BA,IA | | : | | | ________________________________________________________________________ The LISTGROUP display has similar information to the LISTACCT command display. This listing shows your logon group's capabilities and security information. If you have account manager (AM) capability, all of the groups in your account are displayed. To add a new group A user with account manager (AM) capability may create account groups with default attributes as well as those with attributes that you specify. If you have account manager (AM) capability, you may add a new group to your account. Users Users are people like yourself who use the computer. In a sense, users do not have a place in the account structure (cabinet). Instead, they are the people who have the key to an account. A user name is the key to a particular account. To list the users in your account You can use the LISTUSER command to display information about users in your account or other users on the system. The SHOWME command also displays the account, group, and user information associated with your session. You must have account manager (AM) capability to execute the LISTUSER command. To list the users in your account, enter: :LISTUSER Return The screen displays the following information: ________________________________________________________________________ | | | | | USER: USER1.PRACTICE | | | | HOME GROUP: PUB PASSWORD: | | MAX PRI : 150 LOC ATTR: $00000000 | | LOGON CNT : 0 | | CAP: AM,AL,GL,ND,SF,BA,IA | | ******************** | | USER: USER2.PRACTICE | | | | HOME GROUP: PUB PASSWORD: | | MAX PRI : 150 LOC ATTR: $00000000 | | LOGON CNT : 1 | | CAP: ND,SF,BA IA | | : | | | ________________________________________________________________________ Note that the password can be displayed in this example. The password is displayed if you include the ;PASS parameter. Files Files are materials that you create. They are kept in the groups. You can create, save, and edit files. You can also access other files located in another group or account. To display file names To display all file names in the PUB group, use the LISTFILE command. Enter: :LISTFILE Return If no one has created any files for this account, you should now see ________________________________________________________________________ | | | | | NON-EXISTENT FILE @.PUB.PRACTICE. (CIWARN 920) | | | ________________________________________________________________________ Otherwise, you would see ________________________________________________________________________ | | | | | FILENAME | | | | YOURFILE | | | ________________________________________________________________________ Soon you will learn how to create a file.
