How to set the IP and MAC address in C program?

My working environment is Sun250 Server, Solaris 7 operating system. I encountered a problem ---- How to set the IP and MAC address in C program to make the system change it IP & MAC at runtime?
Any idea is welcome! Thanks!

Hi
As a simplest possible solution, you can use the system command
to run ifconfig that can set both the mac address and the IP address of the system. You will have to use setuid though.
Or you can use the DLPI calls ( do a man DLPI or search for a
Sun documentation on the same at http://soldc.sun.com) to write
a pure C program.

How to set the width and heigh in the popup window

Hi All,
I tried to show a report in a popup window style.
In the column link section, I defined the URL like the following:
javascript:popupURL('f?p=&APP_ID.:128:&SESSION.::&DEBUG.::P128_PAY_RATE,P128_PAY_TERMS:#PAY_RATE#,#PAY_TERMS#'). how and where to set the height and width for page 128?
Thank you,
spark

Here is a sample of the JavaScript function I re-use that opens a popup window. You'll notice that it includes the width and height of the popup window:
function callTCPopup (formItem1) {
var formVal1 = formItem1;
var url;
url = 'f?p=&APP_ID.:1111:&APP_SESSION.::::P1111_TC_ID:' + formVal1;
w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
if (w.opener == null)
w.opener = self;
w.focus();
}You could also look at using a Modal Page (Skillbuilders' plugin - watch the video for use).

How to set the HomePage and FolderSize of a managed folder?

Recently, I deside to get the FolderSize and HomePage of a managed folder throw GetFolder operation in EWS, but the FolderSize and the HomePage always not present.
Unfortunately, I could not set these two element directly in Exchange management shell like "StorageQuota".
I tried to create some items in the managed folder, but I also could not get the FolderSize.
How can I do next? Is there anybody know the ways to set the HomePage and FolderSize of a managed folder?

Hi,
We can use the Set-OrganizationConfig -ManagedFolderHomepage command to specify the homepage. To limit the managed folder size, we can use the StorageQuota parameter with the New-ManagedFolder command.
Here is a related article about the Set-OrganizationConfig command for your reference.

How to get imei number and mac address of mobile device on adf mobile

Hi experts,
I need to get imei number and mac address of device (supposed to be works on both android and iphone) on adf mobile
bgrds

Hi,
Adf mobile support phonegap api. Version must be 2.0(you can check it by below code snippet) You can just reach uuid from both platform via cordova. Espescially, IOS restriction limits you to get device infos that you mentioned, but you can get uuid.
   getCordovaVersion = function ()
        var cordovaVersion = device.cordova;
        return cordovaVersion;
    getDeviceUUID = function ()
        var uuid = device.uuid;
        return uuid;

How to set the IP and hostname

Hi All
I have created a new OVM template from the ORACLE 10G VM template. (created a VM from original template and then did a save as template).
Problem is that when I use this template to create a new VM - the hostname and IP (static) is the same as the original VM.
How do I configure the network stuff? (no system-config-network on the VM)
Any help would be great.
TIA

roynor wrote:
The hostname is automatically set from /etc/host. The first name of the entry matching the IP address of the first interface will be used.This is not true. The hostname is set from */etc/sysconfig/network* on an Enterprise Linux server.
However, a lot of the newer VM Templates have a first-boot configuration script that automatically runs from /u01 and is triggered from the */etc/sysconfig/oraclevm-template* file. Before saving your modified guest as a template, change RUN_TEMPLATE_CONF=NO to YES and then shutdown. When the guest starts back up again, it'll run the firstboot configuration again, which includes setting the IP/hostname information and relinking Oracle 10g.

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.

How to set the number and width of divs of Graph?

Hi, everyone.
As the title, I want to design a virtual scope. And there is something I don't know
how to set about Graph. That is I want to set the number of divs of X-axis and Y-
axis with 10 divs of Y-axis and 8 divs ofX-axis. Additon, i also want to set the
width of each divs. How can I do the setup?
Thanks in advance!

There are two ways of doing it.
First, to do it offline, right click on the graph in front panel>> dropdown Menu select 'properties'>> Go to Tab 'Scales' and select relevant values for each axis
Or to do it programatically, create a property node ( as shown in attached pic)>> select property>> x scale range / y scale range>> change it to write>> create a control to it and you can set following attributes: Minimum, Maximum, Increment, Minor Increment, and Start of that particular axis
Hope this helps

Dev
