Creating Oracle users (1) When NPS/X needs to connect to Oracle to get or put data from/to the database, a user name

and password is needed to connect to Oracle. The users in Oracle are internal, system, npsx. When NPS/X connects to Oracle it sends it's user name to Oracle, if the user is not found in

Oracle then Oracle will prompt to login.

User "npsx" is the owner of all NPS/X related tables with a default password "npsx" can beused to login

New users created into UNIX can have their own Oracle user names which in such a way to

helps the administor to monitor which user has modified what, control access levels,

Creating Oracle users (2) The user "npsx" has a role given to it which has full privilege on all needed NPS/X tables, this

role is NPSX_USER. Other roles can be granted to new users to have different access privilegesuch as NPSX_READ_ONLY which will be able to open plans for view purpose only.

Creating Oracle users (3) Create the user in UNIX first then create the user in Oracle. Login as oracle and run the command /users/npsxadm/npsx_oracle/cr_npsx_user

then you will see

Creation of NPS/X user

1. Create user with password

2. Create externally identified user (ops$)

0. Exit

Enter your choice:

Creating Oracle users (4) There are two options

the first requires a user name and password everytime the user connects to Oracle (highersecurity)

the second option gets the information automatically from UNIX (lower security) For an example we will add the user "brown" by using option 2 (option 1 is almost the same) The password for the user system is required 2 times (manager) Then it will show

Enter ops$ username for new user:

which we will enter "ops$brown"

Then it will ask

Enter default tablespace for new user (e.g. users):which you type "users"

Creating Oracle users (5) Then it will ask you to choose a role for this user

These are the roles defined in NPS/X

NPSX_PLANNER

NPSX_REMOTE_COPY

NPSX_READ_ONLY

NPSX_LINK_PLANNERNPSX_ADMINISTRATOR

NPSX_LINK_PLAN_READ_ONLY

NPSX_USER

For an example if you want "brown" to have full privilege then type NPSX_USER , but if youwant "brown" to be able to read only then type NPSX_READ_ONLY (supported starting inNPS/X 3.2).


8/10


Modifying role privileges (1) The need of modifying the roles is needed when you want to control privileges of each user on

each type of data As oracle run the command /users/npsxadm/bin/roles will open a window asking the user name

(npsx) and password as follows


9/10


Modifying role privileges (2) To view or modify the privilege of a role simply retrieve the role from the menu "Role-

>Retrieve", then there will be a window for you to select which role you wish to view or modifythe privileges.

Since the role NPSX_READ_ONLYhas not been correctly

modified to serve the user using this role as the name is

meant to, we will use this as an example.

Select the role NPSX_READ_ONLYand click OK.


10/10


Modifying role privileges (3) Then you will see the privileges granted for the selected role for

each table, you just need to know which object is needed to becontrol to serve your needs (study the NPS/X objects in theDatabase description for more details)

For this example NPSX_READ_ONLY needs to have insert,update and delete privileges on the object NPSX_INFO (andWORKAREA in NPS/X 3.3), so by selecting this object and thenmaking a mark in the boxes below (insert, update, delet) will grant

these rights to the selected object.

Click Role->Update and then Role->Execute will run the scripts togrant the privilege on the selected objects to the role

NPSX_READ_ONLY.
