Then process ask me for password for administrator but it terminates befor i send it. exitCode() returns 1.
Have you some idea how can I do it?
Regards for you.

At the very least, you need to read this and follow the advice it gives. That may or may not solve your problem, but it's a bare minimum.

How to set system date as a default value in UIX/XML page?

Example: We set default values using following statements:
<set property="inputValue" target="${bindings.PoNumber}" value="${'1234'}"/>
<set property="inputValue" target="${bindings.UserName}" value="${param.MyParam1}"/>
In JDeveloper Help, we cannot find a way to set a Date attribute's default value to today's (system) date. Any suggestions?
Also, does anyone have a reccomendation on a good book for uix/xml?
Thanks, Ali.

How to find universal date in java , not system date.

Hello All,
I am working on licensing the java web product using License4j jar. so here i want to get the universal date not system date. because system date can be easily changed by some one. suppose your product license validity date is 15 march 2010. you can change your system date and use this product long life. I have seen some java program from java.util api but not getting the correct answer.

Some of our clients want server for which we are doing the licensing. so admin can change the server date and use this product.Give up in that case. It's not worth the effort. It's probably quite easy to remove the license checks, and you can't create something that is bullet proof. You have to decide when you got something that is good enough.
Some applications checks that last startup time is before the current time and then stores the current time. The administrators of the server would in that case always have to change the time using an increasing value, and they wouldn't bother doing that.
I would however be really surprised if they didn't pay for your software if they want to have a dedicated server, even if you didn't have any license checks. Companies usually don't want to use pirated software since you in that case can sue them.

Setting System Date for the Deadline branch of a block

Hi,
We have a IDocs->XI->File scenario. We need to collect the idocs coming from ISU system and do a N:1 mapping into a single file. We need to end the collection process everyday at a particular time...
In ABAP workflows if we are using a block for its deadline condition we can give %DATUM%. This will provide the system date in that place.
In BPM in XI in place of %DATUM% what we'll have to provide so that we can do the same so that the system date comes into that place.
Thanks & regards,
Jayakrishnan

One more way is to send a "stop collection" message from a proxy, chk this link
/people/siva.maranani/blog/2005/05/22/schedule-your-bpm
you ve to customize what Maranani describes so that the message is a "stop" rather than a "start" , hope it helps

Set system date permanently

dear all.
i have solaris: SunOS unknown 5.10 Generic_147441-01 i86pc i386 i86pc. Is virtualized on oracle virtual box, so when i change date with command:
# date 0909010112
it changes for a few seconds... :S
how can i change date permanently in my system ??
thanks ..

How can i do that???You have a computer.
It is booting to an OS (some OS you didn't feel it necessary to describe).
You installed Virtualbox.
You then installed Solaris 10 within Virtualbox.
Modify the date on that OS that boots the computer.
Your Solaris will sync through to that date and expect THAT date to be the correct one. The date in that primary OS is the controlling date for the entire kit.

How can I set the date of my PC using Java?

Which class has the function to set system date and time.
Thanks in advance.

but the following sentence
Process p=Runtime.getRuntime().exec("date
11-03-2002");
always throw IOExecption error
java.io.IOException: CreatePreocess:date 11-03-2002
error=0
and why?
How to settle it?
'date' is an internal command which means you need a shell to run it. Depending on the OS this will either be 'cmd' or 'command'. If you search the forums with the following keywords you will find examples on how to use this: "exec", "Runtime", "cmd" or "command"

Setting system clock

It probably is a daft question - but please can anyone tell how to set
system date using the java api. By setting system date I mean the
computer's clock.
Thank you.

Java does not have a method for that. You need to access the os commands for that, either via JNI or the Runtime or ProcessBuilder classes. This will make the application non-portable.

Changing system date in a HVM DomN

Hi ,
the changed sytem date in a HVM DomN does not stay persistent after restarting virtual machine.
same problem is also exist in PVM DomN in a different mannger which I had already opened a different thred for it.
1. Create a HVM DomN
2. login into HVM DomN
3. set wallclock
xen.independent_wallclock = 1
4. restart HVM DomN
5. login into HVM DomN
6. set system date to 07/07/2030
*[root@bcvlnx12 ~]# date -s '07/07/2030'*
Sun Jul 7 00:00:00 CEST 2030
*[root@bcvlnx12 ~]# date*
Sun Jul 7 00:00:03 CEST 2030
*[root@bcvlnx12 ~]#*
7. check if ntpd disabled
*[root@bcvlnx12 ~]# chkconfig --list ntpd*
ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
8. restart DomN as root
*[root@bcvlnx12 ~]# shutdown -r -t 0 now*
Broadcast message from root (pts/1) (Sun Jul 7 00:05:20 2030):
The system is going down for reboot NOW!
9. login again as root after restart
Last login: Wed Apr 21 11:10:01 2010 from pcmuc014.bc.int
*[root@bcvlnx12 ~]# date*
Mon Jul 8 02:06:33 CEST 2030
*[root@bcvlnx12 ~]#*
10. system date is persist
11. Login into Oracle VM manager web interface and power off Dom N
12. Login into Oracle VM manager web interface and power ON Dom N
13. login into DomN

*[root@bcvlnx12 ~]# date*
Wed Apr 21 11:30:04 CEST 2010
so , system date which has been ser by root user in step 6 is lost and become same as with Dom0
Any idea ? any fix ?
Rgds.

Hi, for paravirtualized guests do like this:
As user root
vi /etc/sysctl.confsearch "independent_wallclock" and set it "=0" (NOT "=1")
Save and exit
Set the correct Time Zone creating an appropriate symbolic link, for example:
ln -sf ../usr/share/zoneinfo/Europe/Rome /etc/localtimeThen:
vi /etc/sysconfig/clockSet it as you like, but following this schema:
ZONE="Europe/Rome"
UTC=false
ARC=false("ZONE" refers to the Time Zone, "UTC=false" indicates that LOCAL TIME will be used)
Finally, deactivate the ntpd service on your VM guest, as with the above settings system time will be bound to the Hardware Clock on Dom0, therefore we don't need ntpd:
chkconfig --del ntpd
service ntpd stopTry a reboot and check all is ok.
All this, I repeat, is true for Paravirtualized guests only. Fully Virtualized guests do need ntpd service for system tyme sync.

Is there any danger in setting the system date/time to a prior date?

We are dealing with some software digital certificate expiration issues. Until the developer gets them fixed, the only way we can use the software is to set the date/time preferences to a date before the certificate expired. Some users are concerned that this will spell catastrophe for their systems because Unix/Linux based things don't like haivng their dates messed with. I maintain that the only things that would be affected are the date/time stamp on files they save while the settings are changed, possibly any iCal events created during the change (which can be overwritten by the user), and that if they use Time Machine the backups might not be dated correctly (and for that reason I've suggested they shut Time Machine off while their date is changed). I just don't believe it will lead to massive system failure. Who is correct?

Yes you will have issus with DHCP leases/Internet and your router if your time and date isn't current.
Offline you can do what you want. Better to get a temporary workaround from the developer to hold you over.

Set current system date in a field on load of a page

Hi APEX users,
I read about a similar thread on the subject but I am just as confused.
Simply I need assistance with the following:
I have a page that has many fields and one of those fields is DATE_RESOLVED. This is a DATE Picker field but I want this field to show the current system date every time the form loads/reloads BUT yet give the user the ability to change the date if they should choose to do so by way of the DATE Picker calendar.
How would I achieve this?
Any help will be greatly appreciated. My form is functioning just fine but I just need to achieve this one last date function.
Thanks in anticipation for your assistancel.
Rick

Hi Ric,
the follwing should cover your requirements.
a)
On you main page screen, if you click on your particuar date item, say P1_MY_DATE
set the follwing:
#1 under Source,
Source Used: only when current value in session state is null
Source Type: Plsql expression or function
Source value or expression: sysdate
#2 under default
default value: sysdate
default value type: plsql expression
b)
On your main page screen, create a new page computation by clicking on the '+' icon next to computation on the left hand side (page rendering)
location- item on this page (default) -> next ->
compute item: select your item (P1_MY-DATE) -> computation point: Before regions ->computation type: plsql expression -> next ->
computation: sysdate -> next
(leave blank, unless you want this to be conditional) -> create
done...
