Java Operating System Modern Scheduler

Does any one have any examples or samples of an operating systems modern scheduler that was implemented in java?

I doubt you'll find any examples here. Try Google. As far as writting a scheduler in Java that sohould be easy. Look at Timer and TimerTask. I don't know the difference between a modern scheduler and a 'classic' scheduler. The only time I've seen 'classic' used in regards to software, it was synonymous with 'crappy.'

Operating system version {0} is too low. You need at least version {2}

Please can someone tell me what this means?:

It occurs in the \usr\sap\jupgrade\log\CHECKS.LOG file, when I run the 'General Checks' stage of the' PREPARE Module Status' program.
I am trying to patch a SAP 7.01 SAP Portal to EHP2. The server is running Windows 2003 SP2, MS SQL Server 2008 SP1. I believe that the versions of both the OS and DB are sufficient for EHP2. The upgrade will use a 7.2 kernel and I think that the software versions are sufficient for that too.

I have tried to continue by selecting:
Reselect PREPARE modules to be executed again
and chose Finalization. Then Continue.
But it says:
Module selection is invalid Unable to execute module 'Finalization'. Module 'Finalization' can run only after module 'General checks' has run successfully
Then I ran the General checks module again, but it failed again with the same error.
Please can you suggest how I can proceed?
Thanks.

Can you tell me if I have a 64 bit operating system which Java update do I download

Please can anyone advise me on what Java update I download for a Windows 7 64 bit operating system. My Firefox is telling me I need to urgently update my Java but when I click through to update all that is there is a page of confusing information about 32 bit and 64 bit systems. It asks which version am I using 64 bit version of Firefox or 32 bit. I didn't know there were two, I thought when referring to 64 bit and 32 bit it meant the operating system of my computer. Can anyone clear this up for me. Thank you.

Of course, if you have a x64 bit system, its better to download a x64 bit Java version. However, i think Firefox won't be able to use it since Firefox isn't x64 bit (yet). So if you need Java in your browser, you'll need Java's 32bit version.
Keep in mind i could be wrong. It's just my guessing because i tried it out some months ago. I installed 64bit Java but Firefox couldn't handle it.
However in my opinion you won't recognize a difference between 32 and 64 bit, unless you play games in Java or do other resource intensive work. 32bit will always work on a 64bit PC, but not the other way around.

Not only does Adobe flashplayer continue to crash on my operating system (windows 7) but now java script is having issues .... what is wrong with firefox????

for months I have checked the forums, and seen the same issues with Adobe Flash Player ... I have uninstalled and reinstalled too many times now and am totally frustrated with Firefox,. I just get it working again and Firefox updates and then I have the same issues ... and now my java script is screwing up and it never did before .... this all came after the latest update .... is anyone else having these issues or is my operating system under attack???

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:
[[Flash Plugin - Keep it up to date and troubleshoot problems]]
[[Flash 11.3 crashes]]
[[Flash 11.3 doesn't load video in Firefox]]

I have Adobe Photoshop CS4 and have just upgraded my Mac operating system to Yosemite with the newest version of Java 2014 running. When I try to access Photoshop from Bridge or directly open it asks for a Legacy Version of Java 6. As I am a pensioner I cannot afford an upgrade does anyone know of a work-around for this problem?

Hi Daddyfred,
CS4 Photoshop has not been tested on Yosemite. But still you can try the Java 6 update using the below link.

Java Program in Different Operation Systems

Just one question? can I use a java program (.jar) compiled in windows, in my solaris only by copying the .jar , or do I need to compile it with the solaris SDK?
Thanks in advance for your help and sorry for my ignorance.
Javier

Hi,
It is not required to recompile bcoz the .jar file contains .class files which are independent of Operating system which will be taken care (interpreted) by JVM.
Actually there is different JVM's for different operating systems(Windows 98,Unix,OS/2). No need to have differend java class file for different operating system. Pls, remember Java is platform independent language.

S.Prabu

Need more info on Java SE 6 after downloading my new operating system to Yosemite

I updated my operating system on my MacBook Pro to Yosemite 10.10.2, now when I try to open CS4 it directs me to download Java SE 6, but the "more info" button which is to direct to the website to download the Java, does not work, and I can't find anything or where to download this. I need CS4 to do my work, can someone help me?

Is it possible to write an operating system in java?

Our highschool requires us to do a senior project to graduate. It has to be something you want to do as a career. I want to be a programmer so I thought it would be cool if I wrote an operating system. I really don't know where to start though, I thought you couldn't write an operating system in a high-level language at first but then I heard differently. I can see why you'd have to use assembly or someting to write one because it has to be in bionary but i guess that is not true. So is it possible to use java to write an operating system or is that just not possible? I'm only a sophmore right now so i have two years to figure it out but i'd like to get an idea now.
thanks, lateralus

it's not going to have a gui or anything like that,
it's just going to be something similar to DOS. It
really doesn't have to do much. I just like the
challenge, also I heard someone else in my school had
done it and they use java.You sure that you don't just want to write a command shell?
When you open a console window on windows that is a command shell, not an OS.
And writing one of those would be a lot easier than writing an OS.
I suppose you could write a very primitive pseudo OS using the Sun VM. However I am not sure that you would really be able to demonstrate the concepts of an OS except in a very complicated way. For example if you had the following 'OS' commands
1. Store file
2. Print file
Then you could implement it in the following way
- Create a big binary file managed via java
- Storing a file means 'managing' a hunk of that binary file and 'mapping' the file into that space.
- Printing the file would mean
....a Get map to access file (so find it in binary file.)
....b. Read contents (read bytes from binary file)
....c. Print contents to JFrame (or GUI thing)
If the above seems confusing then unless you have a teacher that is either willing to be very free with what a success is or a teacher that understands the concepts very well then going with a command shell would be much better.

Calling Operating System Commands from PL/SQL using java

Calling Operating System Commands from PL/SQL - The Java Way
wlth help of given thread link,
Calling OS Commands from Plsql
but i had user privilege problem
Declare
x Varchar2(2000);
Begin
x := OSCommand_Run('/tmp/sri/GROUP_ho.sh');
DBMS_OUTPUT.Put_Line(x);
End;
o/p;
can't exec: /tmp/sri/GROUP_ho.sh lacks user privilege
i done the grant privillage also
part
dbms_java.grant_permission('abcd', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
dbms_java.grant_permission('abcd', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
dbms_java.grant_permission('
abcd', 'SYS:java.io.FilePermission','<<ALL FILES>>', 'execute');
again
get
can't exec: /tmp/sri/GROUP_ho.sh lacks user privilege
same error;

Process management at the OS level should prevent execution continuing in the calling code until the command has completed (either successfully or with error).
If the low level java code were to spawn child process threads then execution could continue, but I'm guessing the Java function your talking about doesn't do that and just calls the operating system to execute the command and waits for the returning code to come back.
