Administrators and catalog administrators often define multiple catalog items that use the same group of service catalog variables.


Catalog managers and catalog editors can attach a variable set for items and categories to which they are assigned. However, catalog managers and catalog editors cannot create a variable set.

For example, a catalog administrator defines 10 catalog items for types of servers. The request process for all these items asks the same five questions, using the same variables. Associating these variables individually per catalog item is repetitive, time-consuming, and error-prone. Also, to make a single change to multiple catalog items involves manually changing each item. For example, to add a variable to 10 catalog items, you would need to manually associate the variable with each item.

Variable sets allow you to create a collection of structured variables that can be reused across multiple catalog items and order guides. Using variable sets saves time because you do not have to create the same variables individually for many catalog items. Also, when variables should be modified, you can modify the variable set and the changes are reflected across all the catalog items that are associated with the variable set.

Variable sets also allow you to define catalog client scripts and UI policies that are applicable to the variables in the set. A catalog administrator can provide read, write, and update roles to access a variable set. When you access variables of a variable set, a validation is first done at the variable set level, and then at the variable level. If the access is blocked at the variable set level, then the access settings on the variable are over-ridden.

If the access is allowed at the variable set level, then access at the variable level is verified.

Use a single-row variable set to capture data from variables that are grouped together, while submitting a catalog item request for a single entity. Use a multi-row variable set to capture variable data in a grid layout while submitting a catalog item request for a group of entities. For example, for HR during the reorganization of employees, a single record producer should be able to capture the relevant information such as the department and manager for a group of employees.

Also, when you request a catalog item to order virtual machines and servers, configuration options should be captured as a single request. In this case, a requester can define multiple hardware units as rows and their configuration options as columns of a multi-row variable set. You cannot set Global as True for any variable that belongs to a multi-row variable set.Windows 10 has been on the market sincebut the Windows OS family has a much longer history.

Along the way, a number of versions of Windows did very well, particularly Windows XP, Windows 7, and of course, Windows The popularity has kept the OS alive even as the computing world has changed radically, and the age of the lineage means that the operating system has a wealth of legacy features that the most modern versions still support. One of those legacy features and one that is still in use today and a useful feature it is, too is the environment variable.

Environment variables have been a powerful feature of Windows from the earliest days; in fact, they predate Windows and derive from MS-DOS. Despite their age, environment variables are a useful way to control the way Windows operates with an extremely small footprint in terms of memory usage. For example, one common environment variable is called PATH, which is simply an ordered text string containing a list of directories that Windows should look in when an executable file is invoked.

Hi Robin, Thanks for your reply. Can you make me understand why i need to install x-manager in windows to open DBCA tool in linux machine? What is the relation in between them? Regards, Maddy. The X-windows client-server relationship seems a bit confused. When you connect to a unix host you'd normally consider this as your server, because you connect to it and say "start an X-windows tool", what you are actually doing is starting a client on the unix host that connects to your desktop i.

To make your desktop an X-windows serveryou need the software installed and the security set to allow the connection. Usually a command to the X-server software host unix. Join Date: Dec Easiest way is to install xming x-server on your desktop and enable X11 forwarding on your ssh client?

Are you trying to start this application from a non-graphic terminal? If not, have you modified the default. If it's not logged on, or it's a different userid, this will fail. If you're coming in from another machine, and you're at the main display of that machine and it's running X, then you can use "ssh -X hostname" to connect to that host, and ssh will forward the X display back.

Are you running this from within an X11 environment?

You can use a terminal window, but it has to be within X either after a graphical login, or by running startx. If you've connected from another machine via SSH, you use the -X option to display the graphical interface on the machine you're sitting at provided there's an X server running there such as xming for windows, and your standard Linux X server.

You can usually find 'xauth' in a package with the same name. Very Easy, Had this same problem then what i did was to download and install an app that would help in displaying then fixed the error. Once Xming is installed, run the application called 'XLaunch' and verify that the settings are as shown:. I have had the same issue in Ubuntu There may be security constraints, just know about it.

This worked for me. May be this page is initializing some variables to enable jconsole to connect with that server. I resolved by installing. What worked for me was to setup xming server on my windows machine, set X11 forwarding option in putty when I connect to the linux host and put in my windows ip address with the display port and then the display variable with my windows IP addressDisplay, set, or remove CMD environment variables.

It is good practice to avoid using any delimiter characters spaces, commas etc in the variable name. Delimiter characters can be used in the value if the complete assignment is surrounded with double quotes to prevent the delimiter being interpreted. Any extra spaces around either the variable name or the stringwill not be ignored, SET is not forgiving of extra spaces like many other scripting languages.

The first character of the name must not be numeric.

The CMD shell will fail to read an environment variable if it contains more than 8, characters. Type SET without parameters to display all the current environment variables.

Placing expressions in "quotes" is optional for simple arithmetic but required for any expression using logical operators. Multiple calculations can be performed in one line, by separating each calculation with commas, for example:. The numbers must all be within the range of 32 bit signed integer numbers -2, through 2, to handle larger numbers use PowerShell or VBScript. Numeric values are decimal numbers, unless prefixed by 0x for hexadecimal numbers, 0 for octal numbers.
