Server Admin - How current is the data?
Good afternoon.
When I view the DHCP data in Server Admin, how current is the data? When I close down workstations and logon others, the data displayed, even after multiple refreshes, does not change. A quit & relaunch doesn't update the data either.
Can I rely on Server Admin to provide a current, accurate view?

I'm not sure of the frequency at which Server Admin re-polls the data, but nothing is cached so at the very least each time you connect to a server you're seeing data that's valid up until then.
However, in the case of DHCP you need to consider lease duration.
If your lease is set to something like 3 days then any given client will remain in the DHCP leases list for that long.
In other words, assuming you have one DHCP client on your network and that machine boots on Monday Afternoon, then that machine will appear in the DHCP leases list until at least some time on Thursday afternoon. The number of leases will not decrease when the machine shuts down on Tuesday, nor increase if that machine comes back online before the original lease expiration (it will just be re-issued the same DHCP lease/IP address/etc.). Therefore your lease counter will remain at 1 even when the machine is offline.
Is it possible that accounts for what you're experiencing? The number of leases does not reflect the number of active DHCP clients on your network, just the number that have been active within the last (lease duration) hours.

You cannot use OPEN DATASET to transfer data from application server to presentation server.
You can do the following :
<b>Do 1st point in BACKGROUND</b>
1. Read the data file from application server into an internal table using OPEN DATASET
<b>Do 2nd point in Foreground</b>
2. Once you get the data into an internal table, then use FM GUI_DOWNLOAD to download it on presentation server
You cannot use the above 2 point together in Background because its not possible. Hence you need program it partially in background and partially in foreground.

any body help me?
Thanks
There are basically three ways to go:
1) Get compatible software. Microsoft iSCSI target cannot do what you want out-of-box but good news third-party software (there are even free versions with a set of limitations) can do what you want. See:
StarWind Virtual SAN [VSAN]
http://www.starwindsoftware.com/native-san-for-hyper-v-free-edition
DataCore SANxxx
http://datacore.com/products/SANsymphony-V.aspx
SteelEye DataKeeper
http://us.sios.com/what-we-do/windows/
All of them do basically the same: mirror set of LUs between Windows hosts to emulate a high performance and fault tolerant virtual SAN. All of them do this in active-active mode (all nodes handle I/O) and at least StarWind and DataCore have sophisticated
distributed cache implementations (RAM and flash).
2) Get incompatible software (MSFT iSCSI target) and run it in generic Windows cluster. That would require you to have CSV so physical shared storage (FC or SAS, iSCSI obviously has zero sense as you can feed THAT iSCSI target directly to your block storage
consumers). This is doable and is supported by MSFS but has numerous drawbacks. First of all it's SLOW as a) MSFT target does no caching and even does not use file system cache (at all, VHDX it uses as a containers are opened and I/O-ed in a "pass-thru" mode)
b) it's only active-passive (one node will handle I/O @ a time with other one just doing nothing in standby mode) and c) long I/O route (iSCSI initiator -> MSFT iSCSI target -> clustered block back end). For reference see:
Configuring iSCSI Storage for High Availability
http://technet.microsoft.com/en-us/library/gg232621(v=ws.10).aspx
MSFT iSCSI Target Cluster
http://techontip.wordpress.com/2011/05/03/microsoft-iscsi-target-cluster-building-walkthrough/
3) Re-think what you do. Except iSCSI target from MSFT you can use newer technologies like SoFS (obviously faster but requires a set of a dedicated servers) or just a shared VHDX if you have a fault tolerant SAS or FC back end and want to spawn a guest VM
cluster. See:
Scale-Out File Servers
http://technet.microsoft.com/en-us/library/hh831349.aspx
Deploy a Guest Cluster Using a Shared Virtual Hard Disk
http://technet.microsoft.com/en-us/library/dn265980.aspx
With Windows Server 2012 R2 release virtual FC and clustered MSFT target are both really deprecated features as shared VHDX is both faster and easier to setup and use if you have FC or SAS block back end and need to have guest VM cluster.
Hope this helped a bit :)

How to change the date path of Web Server to my system time?
Hi,
I have downloaded a Countdown SWF file from the Internet. It is working fine with the Computers which have Internet Connection. But not working without Internet connection because of the following line of code in XML file:
<PHPurl>http://www.flepstudio.org/utilita/CountDown/gettime.php</PHPurl>
When I opened the webpage using the above code, it shows time in a typical digits:
Monday, October 18, 2010 9:12:52 PM in my System -shows in Web browser like : time=1287425579
How to modify the code so that I can use my System time to work with Countdown without Internet Connection.
The following is the path from where I have downloaded the Countdown file:
http://www.flepstudio.org/forum/flepstudio-utilities/2960-flash-cs3-countdown.html
Please help me to run this countdown without internet access.
Thanks.It appears all that php file does is return a time=value variable. So you need to see where that time variable is implemented in the Flash file and assign it a value using the Date.getTime() method instead of having the PHP file get called into play. Look in the help documents or Google if you do not know how to use the Date class.

How to filter the data on Reports from collected from differnet Agents
1) I have to write a Plug-in which would fetch the same type of data from 7 Agents. I need to generate the report for each Agent separately,This plug-in will be deployed in various different environment. So I will not know the host name as it will be deployed different environment. Can anyone suggest how to filter the data for each agent from the table. I see one solution of using Bind variable for the Target GUID in PL/SQL file. Can you please suggest if there is any other better way of doing this.????
Also Can you please suggest what are the best ways to debug the OEM Plug-in?
Thanks Anyway.....What I mean filtering data means displaying data for each Agent Seperatly. Assume I have collected Filesystem data from 5 Agents (5 different server). Now I want do display file system data for Agent1 (server 1). How would I fetch it from MGMT$Metric_Current. Currently I use a bind variable
??EMIP_BIND_TARGET_GUID?? to filter the data for a Agent from MGMT$Metric_Current view. I compare Target Name entered while deploying Plug-in with the Target_Name column of specified view.Is there any other way of fetching data from this table for a Agent?
I hope I am prety clear now. My Problem is IO dont want to force user to enter exact Server name while deploying Plug-in.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.
If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
This page is a good starting point for learning about Flex and PHP communication:
http://www.adobe.com/devnet/flex/flex_php.html
Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/ -
How to validate the dates in the table control ?
How to validate the dates in the table control ?
Can I write like this ?
LOOP AT it_tab .
CHAIN.
FIELD : it_tab-strtdat,it_tab-enddat.
module date_validation.
ENDCHAIN.
ENDLOOP.
Module Date_validation.
ranges : vdat type sy-datum.
vdat-sign = 'I'.
VDAT-LOW = it_tab-STRTDAT.
VDAT-HIGH = it_tab-ENDDAT.
VDAT-OPTION = 'BT'.
APPEND VDAT.
WHAT CODE I have to write here to validate ?
and If I write like this How can we know which is the current row being add ?
It loops total internal table ..?
Bye,
Muttu.Hi,
I think there is no need to put chain endchain.
To do validation you have to write module in PAI which does required validations.

How to import the data in a .xls or .xlsx file into a oracle database table
Hi,
Please tell me how to import the data in a .xls or .xlsx file into a oracle database table in Oracle 10gR2 using Oracle Warehouse Builder 10gR2.....can we do something through Non-Oracle->ODBC?Yes, it is possible, look at this thread
[SQLServer access from AIX Warehouse builder|http://forums.oracle.com/forums/thread.jspa?messageID=2502982]
If your server (with target DB and OWB runtime) is on Windows OS this configuration will be simpler - you can use single server.
And additional link on OWB blog (with 11g transparent gateway)
[http://blogs.oracle.com/warehousebuilder/2008/01/11g_heterogeneous_agent.html]
(configuring nonoracle connection with 10g generic connectivity very similar to 11g gateway)

How to Hightlight the Data in Jsp Page
How to Hightlight the Data in Jsp Page,
I am doing doing search page,based on values given search page those are sent to servlet,in servlet based on some conditions if particuler id i am getting then i am redirecting to Respective jsp page with highlight the data from database..
Thanks in advance..."Highlighting data in JSP sounds strange".
Without looking at your search specific algorithms I feel you are finally going to display a page (HTML content) to user which contains highlighted text. Highlighting is not directly related to server side language you use (JSP, ASP, PHP etc.). This is purely HTML and CSS. However, server side script (such as JSP) should generate HTML content for getting highlight effect.
Following HTML shows highlighted text using background-color property on span element.
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
</head>
<body>
<p style="font-size:1.1em">This is a long paragraph which contains <span style="background-color: yellow;">highlighted text</span> and non highlighted text.</p>
</body>

How to save the data of ABAP report into a notepad in desktop location???
HI all,
Can any one tell me how to transfer the data of ABAP report into a Notepad.
Actually I have to schedule a ABAP report in background on daily basis and I want to transfer the
whole record into Notepad.
If any program is available for this..please clearify the relevent code for transferring.
Thanks
Rajeevdeclare a character type internal table.
now move your data from it_data ( internal table with data ) into table itab.
since you are running this report in background, you cannot save it to the desktop. Instead give any app server location
data: itab(400) occurs 0 with header line.
field-symbols: <fs1> type any.
data: gv_file type rlgrap-filename default 'TEST.TXT'.
data: gv_filepath type rlgrap-filename default <path>.

ASSIGN COMPONENT sy-index OF STRUCTURE it_data TO <fs1>.
IF sy-subrc = 0.
CONCATENATE itab <fs1> INTO itab SEPARATED BY ' '.
ELSE.
EXIT.

How to Audit the data displayed within a Webi report
Hi All,
We have BOBJ XI R2 SP4 installed on our server.
One of the requirements is to audit the data the user has viewed through Canned reports and also Adhoc reports created in Webi.
I understand that we can audit what reports are accessed by the user, but not sure how to audit the data within the report. Could someone please let me know if auditing data can be acheived form SDK ? If so how ?
Thanks,
SireeshaPablo,
The following should get you started;
This is a report to pull Universe Name, Report Name, Action Time (last refreshed), Action Duration (execution time), User Name and Object Name (universe objects used in reports).
The Result Objects are as follows:
Object Name from Actions/Action Details
Action Time from Actions
Action Duration from Actions
Action Type from Actions
Action Type Detail from Actions (detail object associated with Action Type)
User Name from Actions
Document Name from Actions/Document
Universe Name from Actions/Action Details
The Query Filters are as follows:
Action Time between Day1 And Day2
Note: The Query Filter is necessary (obviously) only to restrict the size of the query. I wouldn't run this query without a filter on demand. Depending on the size of your deployment, you might want to restrict the query initially to a specific universe/list of universes while testing.
At the report level, I moved Universe Name and Document Name in to (nested) sections.
i.e.
Section on: Universe Name
Section on: Document Name
Table
Another option would be to retrieve this information from the CMS tables using WID Scanner [here|http://www.forumtopics.com/busobj/viewtopic.php?t=80856]
The last option would be to use the Report Engine SDK (for Webi) to write a program extract this information from the CMS tables and pass it to another table. WID scanner (above) does effectively the same thing, passes the info to an MS Access table (if I remember correctly..I may be wrong. I have'nt used it since it last tried to create a report to extract all used objects.)
Best,

What does this mean?
So I browse through forum & i got to know that i need to initial the UTL_FILE_DIR ="C:/OracleProject" in init.ora
So can i edit the init.ora with notepad.When i tried to do that it says permission denied
In my system it shows the init.ora file in path C:\oraclexe\app\oracle\product\10.2.0\server\config\scripts
but there is also other file initXETemp in the same path do i need to do the changes in it.
I have tried even editing the SPFILE as mentioned below:
C:\oraclexe\app\oracle\product\10.2.0\server\dbs\SPFILEEXE - I had edit this file using notepad & set the value of UTL_FILE_DIR ="C:/OracleProject". So next time when i restarted i'm unable to log on to the database.
So i had reinstall the software again.
Could you please let me know how to proceed..hi,
I have created the directory from sys database

hey guys
i installed the sqlite and sqlite-net as requested in other answers i found, changed to x86, and add the .db3 file in my project.
but the problem is how to retrive the data that already in the file( i am not creating any table or data in the app, just read)
all the answer i found is to create a table first and then read the table, i tried to skip the step of creating a table, and read from the table directly, but failed with " no such table", by the way, i set the property of the .db3 file as "content",
"copy if newer"
can anyone please help? i appreciate that !Hello,
From your description, you want to read data from available sqlite file. When you add the sqlite file into your project, you need to change the sqlite file build action to content. After deploying to device, the sqlite file is located in installation folder,
you need to copy that file into storage folder before reading data. Please try the following code snippets.
private async void Button_Click_9(object sender, RoutedEventArgs e)
//check if file exists in storage folder, and then copy to local storage
bool flag = await FileExistsAsync("Data.db3");
if (!flag)
var folder = await Package.Current.InstalledLocation.GetFileAsync("Data.db3");
await folder.CopyAsync(Windows.Storage.ApplicationData.Current.LocalFolder);
// open sqlite and read data
public async Task<bool> FileExistsAsync(string fileName)
try
await Windows.Storage.ApplicationData.Current.LocalFolder.GetFileAsync(fileName);
return true;
catch (FileNotFoundException)
return false;
