Please let me know a good query to find out the memory being used in DB

Hi All,
We are using Automotic memory management by using parameter memory_target option. I want to find out the total memory being used and which is free.
ie;(SGA+PGA). Please let me know.
Thanks & Regards,
Vikas Krishna

Since we are using memry_target we will not get an accurate value there I guess.

Query to find out the time used by an user for an application

Hello All,
I want to know the query to find out the whole time used by the user for an application. Please view the below data
Employee:
SNO EMP_ID EMP_NAME EMP_DATE LOGIN_TIME LOGOUT_TIME
1 10 Visu 21-Nov-2010 06:30:00 07:30:00
2 10 Visu 21-Nov-2010 06:40:00 07:20:00
3 10 Visu 21-Nov-2010 06:50:00 07:50:00
4 10 Visu 21-Nov-2010 07:30:00 08:30:00
5 10 Visu 21-Nov-2010 09:30:00 10:30:00
By checking the above data we can say that the total time Visu used the application is
8.30 - 6.30 (From 1,2,3,4 records) = 2hrs
10.30 - 9.30 (Based on 5th rec) = 1hr
So the total time Visu used the application would be 3 hrs = 180 mins.
Could you please help me in getting the result from that data using a query?

Could anyone please let me know how to set a ICC profile with Acrobat dlls using Csharp or VB

Could anyone please let me know how to set a ICC profile with Acrobat dlls using Csharp or VB

Cant we even use the dlls in an application?
In order to automate Acrobat, you need to have Acrobat installed. There is
nothing you can do with just the DLLs. As was already stated, Acrobat is
not licensed for use on a server, but regardless of that, it's also
not technically suitable for server use. You need to find a solution
outside of Acrobat to solve your problem.
It also seems that you don't have a good understanding of what is going in
inside a PDF file. PDF is a very complex file format, and based on
your questions
and followup questions, you need to spend a considerable amount of time
getting familiar with the PDF file format to understand how color works in
the PDF context. Reader the PDF spec, while paying special attention to the
section about color. You will find out that if you want to convert the
color space of a "PDF file", you actually need to convert the color space
associated with every single object in your PDF file. That is fairly simple
for vector graphic and text, but when it comes to images, you may have to
convert the image data. Once you have a good understanding of what it is
you need to do within the PDF file, then you can start looking for tools
that allow you to do that. Again, Acrobat and therefore the Acrobat SDK is
not suitable for this task. If you want to stay with Adobe products take a
serious look at the PDF Library, which his licensed through Datalogics (
http://www.datalogics.com/products/pdf/pdflibrary/). As you've mentioned,
there are other, non-Adobe PDF libraries that you can also use, but this is
the Acrobat SDK forum, so I won't discuss any of those 3rd party solutions.
You are wasting your time while looking for a simple solution that does not
exist.

ortonThis is not possible. The best you could do is to have a good guess.
Or how would you parse some dynamic statement as this:
   v_suffix := 'loyees';
   v_sql := 'Select count(*) from (select ''nonsense'' col1 from emp'||v_suffix||') where col1 = ''Y'''';
   execute_immediate(v_sql);
...What is the table name? How do you want to parse that?
Better rewrite all dynamic SQL statements into non dynamic ones. Or do the source control logic for those dynamic parts in an extra module. For example implement your own dependency table and force every developer to add there all dynamic parts.

Need query to find out the sum till a period

Hi,
I need to write one query to find out the cumulative sum of raw_cost of table pa_budget_lines till the specified period, I tried to do this by analytical function, but that is not working in Report 10g. Can anybody help me in this.
Thanks

not familiar with report but could you do something like this
with t as
select 1 grp, 10 * level the_cost, add_months (sysdate, level) effective_dt from dual connect by level < 11 union all
select 2 grp, 5 * level the_cost, add_months (sysdate, level) effective_dt from dual connect by level < 11
input as
( select null grp, null the_cost, null running_total, v_eff_dt effective_dt   from dual)
select * from(
select t.grp, t.the_cost, sum(t.the_cost) over (partition by t.grp order by t.effective_dt) running_total, t.effective_dt,
       lead(t.effective_dt) over (partition by t.grp order by t.effective_dt) next_effective_dt,
       input.effective_dt inp_eff_dt
from t, input
where inp_eff_dt between effective_dt and next_effective_dtv_eff_dt would be the input date you are interested in

Query to find out the free disk space on C: drive

Hi Guys,
I am trying to create a query in Queries section under Monitoring, To find out the free disk space of C: drive.
Am using the below query, but it shows lot many fields, I need only Machine names of the collection and their
Free Disk Space on C: drive
select * from SMS_R_System inner join SMS_G_System_LOGICAL_DISK on SMS_G_System_LOGICAL_DISK.ResourceId = SMS_R_System.ResourceId where SMS_G_System_LOGICAL_DISK.DeviceID = "C:" and SMS_G_System_LOGICAL_DISK.FreeSpace > 1024

The SELECT part of the query will govern what fields you are shown, so perhaps try:

from SMS_R_System
inner join SMS_G_System_LOGICAL_DISK on SMS_G_System_LOGICAL_DISK.ResourceId = SMS_R_System.ResourceId
where SMS_G_System_LOGICAL_DISK.DeviceID = "C:" and SMS_G_System_LOGICAL_DISK.FreeSpace > 1024

Query to find out which workflow(s) use a particular message ? wf_messages

Hi guys
Hoping someone can help.
I've a list of particular notfication messages, which are stored in the WF_MESSAGES_TL and WF_MESSAGES table, and I need to find out which workflows use them.
Can anyone tell me what table I can query to find this out ?
There's no referential integrity which I can use to find this out, and google has turned up nothing so far.
Any ideas ?
Thanks a lot
Scott

You can use this and tweak it around:
select p.process_item_type, p.process_name, p.activity_name, a.message
from wf_process_activities p, wf_activities a
where p.process_item_type=a.item_type and
p.activity_name=a.name and
a.end_date is null;-- means the active/current activity
