How can i know the servlet is running or not?

Hi all,
I have a doubt regarding servlet. I created one servlet and deployed in server. Now i called (RUN) the servlet from the browser. And it is running. Now can i know that the servlet is running or not in the server without seeing in the browser. Can we know the status of the servlet with its URL in the server whether it is running or not?
Let me explain my problem. In my servlet it will run continously read one table and do some operation depending on the entries in that table. Now i called the servlet from the browser. After some time i closed the browser. If browser is there i can know whether servlet is running or not. But now how can i know that servlet is running or not. Becoz eventhough we closed the browser the servlet will run in the background. How can i achieve this?
Thanks and Regards,
VJR.

Hi!
With first call, the servlet will be loaded, and it remains so until server-shutdown, but you need a timer-mechanism execute method calls continuously.

Thomas

How can I know the kernel is running on GPU?

I write a kernel, and then I load the PBJ byte file into a flash as a filter,but when I adjust the parameters of the filter, the usage of CPU keeps increasing rapidly, so I am wondering whether the kernel is REALLY running on GPU?

It isn't GPU-accelerated in Flash Player 10.0 and 10.1. It runs multi-threaded on your CPU.
See:

How can I know the name of instance (SID)?

Dear all,
After I install the Oracle client in my computer, I would like to change the tnsname.ora. However, I don't know the name of instance (SID) because I am not the one install the database and the DBA is gone. So, how can I know the SID name and the port number as well.
Best Regards,
amy

Hey,
The sid defaults to the database name.
http://www.adp-gmbh.ch/ora/misc/identifiers.html
you can find it by
select name from v$database;
or by
show parameter db_name (run this in sql prompt)
Run the above on the database server.

How can I know the version of Application Server Java Virtual Machine

How can I know the version of Application Server Java Virtual Machine?
Thanks a lot.

Thats easy. Your jdk/jre are located in the App Server home directory. Just run the java command under the jdk directory with the "-version" switch and it will provide you with detailed information about your VM.
For example if you're doing it at command prompt it will be something like
java -versionI hope this will be useful to you.

How can I know the database is using Cost Based or Rule Based?

Hi all expertise,
How can I know the database is using Cost Based or Rule Based?
If cost based it is using, what methods are need to use to minimize the cost when database is running? And which tables I can see the performance of the database?
Thanks
Amy

how to see database setting ?
use this
SQL> sho parameter optimizer
NAME TYPE VALUE
optimizer_dynamic_sampling integer 1
optimizer_features_enable string 9.2.0
optimizer_index_caching integer 0
optimizer_index_cost_adj integer 100
optimizer_max_permutations integer 2000
optimizer_mode string CHOOSE
choose means if table statistics is available then it will use cost
else
use rule based optimizer
for seeing performnace of table use
set autotrace on
and run your query
if it doen't show cost.it means it use rule based
for using cost based
u will calculate table statistics
9i
dbms_stats.gather_table_stats('owner','table');
8i
analyze table <table_name> compute statistics;
hope it will help you

How can u know the process chain total time, individual time?

Hi guru's
How can u know the process chain total time, individual time?
and what options will available in sm37?
Thanks
prabha reddy

Hi Prabha
Iam not very sure about total time and individual times.
But you can go to tcode rspcm for monitoring the daily process chains. it gives you details like 1. status 2.start date & time 3. Log ID of each process chain.
or you can go to log view of particular individual chain to know how long it has run.
SM37: tcode for simple job selection.
here you check the status of job.
you can select for certain conditions like
1. scheduled
2. released
3. ready
4.active
5. cancelled
Assign points if it was helpful

How can i know the table fragments

Hi
How can i know the table is fragmented.
Thank you

If you're in 10g you could try use the Segment Advisor to identify various issues etc with your table. This will also provide recommendations on how to improve things.
(below script shamelessly stolen from the brilliant Oracle Base website)
-- segment_adv_table.sql
-- Use Segment Advisor to analyse a table.
-- Original Version
-- http://www.oracle-base.com/articles/10g/SpaceObjectTransactionManagement10g.php
-- owner is SCOTT
-- table is EMP
-- do a search/replace to change these 2 values and re-run it ;)
DECLARE
l_object_id NUMBER;
BEGIN
-- Create a segment advisor task for the SCOTT.EMP table.
DBMS_ADVISOR.create_task (
advisor_name => 'Segment Advisor',
task_name => 'EMP_SEGMENT_ADVISOR',
task_desc => 'Segment Advisor For EMP');
DBMS_ADVISOR.create_object (
task_name => 'EMP_SEGMENT_ADVISOR',
object_type => 'TABLE',
attr1 => 'SCOTT',
attr2 => 'EMP',
attr3 => NULL,
attr4 => 'null',
attr5 => NULL,
object_id => l_object_id);
DBMS_ADVISOR.set_task_parameter (
task_name => 'EMP_SEGMENT_ADVISOR',

so please how can i know the linked email to my phone
Thank you

Welcome to the Apple community jorjh.
If you mean that Find My Phone is asking for a password to a different Apple ID to your current Apple ID.
This feature has been introduced to make stolen phones useless to those that have stolen them.
However it can also arise when the user has changed their Apple ID details with Apple and not made the same changes to their iCloud account/Find My Phone on their device before upgrading to iOS 7, or if you restore from a previous back up made before you changed your details.
The only solution is to change your Apple ID back to its previous state with Apple at My Apple ID using your current password, you don’t need access to this address if it’s previously been used with your Apple ID, once you have saved these details enter the password as requested on your device and then turn off "find my phone" and delete the account from your device.
You should then change your Apple ID back to its current state, save it once again and then log back in using your current Apple ID. Finally, turn "find my phone" back on once again.
