Module column of v$session

Hi:
Is this the right column to see what's the name of the program a
user is running? Why most of them are blanks? Can I assign a
value to this column? What should I do if I want this column to
show the name of self-developed applications? Thanks.

Michael,
Use the plsql package dbms_application_info to set this:
dbms_application_info.set_module( 'module_name','action_name' );
or
dbms_application_info.set_action( 'action_name' );
These will set those columns.
You may have to load 'dbmsutil.sql' as SYS. Ask your DBA.

Adding time module column using c#

Hi All,I use NI GUI Example in c#
and I need to add time module column to the execution view by code.
I use: "axExecutionView.Columns.Insert("_MODULE_TIME",NationalInstruments.TestStand.Interop.UI.SeqViewColumnTypes.SeqViewColumnType_Expression,100,-1);"
but it doesn't work,
Tnx,

For tracing, using the following expression for the column will work:
(PropertyExists("Locals.ResultList") && PropertyExists("Step.TS.Id") && GetNumElements(Locals.ResultList) > 0 && PropertyExists("Locals.ResultList[" + Str(GetNumElements(Locals.ResultList) - 1) + "].TS.ModuleTime") && Locals.ResultList[GetNumElements(Locals.ResultList) - 1].TS.StepId == Step.TS.Id) ? Str(Locals.ResultList[GetNumElements(Locals.ResultList) - 1].TS.ModuleTime, "%f") : ""
Of if what you really want is TotalTime, change ModuleTime above to TotalTime.
The problem is when you hit a breakpoint and it refreshes the whole step list, you will then only get the time for the last step.
The reason why this is a harder problem than you might think is that the time results for a step are not stored on the step itself, they are only stored in Locals.ResultList and only if the step was actually set to record results. The expression above just looks at the last result in the result list and if it is for the current step, then it displays the module time for that step. This works while tracing because only the previous step at the tracepoint is refreshed. At a breakpoint, when it tries to refresh the entire view, only the last step matches the last result. If you wanted it to work in more cases you'd have to do somewhat of a search through the result list for each step, which would be slow and tricky to implement in an expression.
Another alternative you might want to consider is using the On-The-Fly report generation setting instead. That generates the report while the steps are still executing, and the report already includes the module times (or at least it can depending on what settings you use for the report).
Hope this helps,

COMMAND column in V$SESSION table

Is there any table which stores all the meaning of various values that can be stored in COMMAND column of V$SESSION table
Like 3 is for SELECT and 47 for Execute, I found some documentation in data dictionary but was wondering if there is some table that can be used when a trigger or procedure is running to pull the values on the fly.
Thx

You can find the various values for V$SESSION.COMMAND in Table 7-5 COMMAND Column of V$SESSION and Corresponding Commands found in the link below to build your own table.

SECONDS_IN_WAIT column of v$session in 10gr2!!

Hi, all.
Recently, I have found the unbelievale value for SECONDS_IN_WAIT in v$session view. The database is 10.2.0.2.0.
select sid, wait_time, seconds_in_waits,wait_class, event,state from v$session;
SID WAIT_TIME SECONDS_IN_WAITS WAIT_CLASS EVENT
500 0 117874 Cluster gc buffer busy WAITING
In the above example, session 500 is waiting for something for 117874 seconds.
117874 seconds is 32.7 hours(117874/60/60).
Thus, session 500 is waiting for 32.7 hours.
The unit of SECONDS_IN_WAITS column is really "seconds"????
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/dynviews_2088.htm#REFRN30223
Thanks and Regards.

Hi, yes the metric is on seconds, you must review the definition for this field on the view, look this.
 
 
If WAIT_TIME = 0, then SECONDS_IN_WAIT is the seconds spent in the current wait condition.
 

If WAIT_TIME > 0, then SECONDS_IN_WAIT is the seconds since the start of the last wait, and SECONDS_IN_WAIT - WAIT_TIME / 100 is the active seconds since the last wait ended.

 
 
 
Regards.

How to enable AI(accent insensitiv) for one column without changing session

Following is my test SQL:
create table accent_test(col varchar2(10 char);
insert into accent_test values('INDIA');
insert into accent_test values('india');
insert into accent_test values('InDiÄ ');
Following SQL can only enable CI(Case insensitive), but can’t enable AI(accent insensitive):
select *
from accent_test
where NLS_UPPER(col, 'NLS_SORT=GENERIC_BASELETTER') LIKE NLS_UPPER('INDIA', 'NLS_SORT=GENERIC_BASELETTER')
COL
INDIA
india
Upper SQL can’t return the third row ‘InDiÄ’ which includes accent character.
I know following SQL can enable AI by changing the session. However it will change the whole session and other columns in one table:
SQL> ALTER SESSION SET NLS_COMP=LINGUISTIC;
SQL> ALTER SESSION SET NLS_SORT=GENERIC_BASELETTER;
Is there any solution to enable AI for only one column without changing the session?

convert(<Any Chinese Character>, 'US7ASCII') will all return same character '?'.might be an matter of using the right characterset:
SQL> select 'ä' str, convert('ä', 'JA16SJIS') converted_str from dual union all
select 'á', convert('á', 'JA16SJIS') from dual union all
select 'â', convert('â', 'JA16SJIS') from dual union all
select 'à', convert('à', 'JA16SJIS') from dual
STR CONVERTED_STR

About the last_call_et column in v$session

Hello,
Can someone help me about a behaviour that is very strange ...
We have connection about SAS on a database which manipulate Oracle table and others SAS Structure.
The query is a "join" about that table and a "SAS Table" between million of lines in the Oracle table one ....
It last a long time ....
During the query, we have time to see at the v$session table...
At any time (it lasts 3h), we saw that the column 'last_call_et' of the v$session never change : it continuesly stay at 0.
What does it mean ? it means that SAS send a query every second ? Or this column shows the last "internal call"?
If this is the right reason, i would'nt understand why, when i take the same query( launched by SAS) in TOAD, there is no the same behaviour and this behaviuor is in that case the right behaviour : the session is ACTIVE but the last_call_et respresents really the time since i launched the query... So why when SAS do it, the last_call_et stay at 0 ? it works like SAS launch every second this query !!!!
Can someone help me ?
Thanks ...

A parse is also a database call, as is an execute ... I feel that perhaps I was a little too concise with my description. You asked why SAS could be doing lots of calls (although that wasn't exactly how you put the question) and I replied that calls could include fetches. And yes, the last_call_et is reset on every fetch (amongst other things - and ignoring the special behaviour of background processes).Ok

But the explanation of Oracle of the term 'cal' is not so precise at all ...

all_rows plan => parse call, execute call ..... with very long call time, lots of fetch calls
first_rows_n plan => parse call, execute call ... with very short call time, lots of fetch calls
In the first case you would see last_call_et constantly growing until the fetches started
In the second case last_call_et would keep resetting to zero so fast you probably wouldn't see it as a non-zero value.
I don't understand : ok for the conséquences on the timing ... but if there are a lot of fetch call in both cases : the behaviour on the 'last_call_et' has to be equal ?True - but in one case I've included an execute call that is active for a very long time, and in the other I've proposed an execute call that is active for a very short time. (And execute calls are calls, and I did ask you about the exact details of your observations.)Ok
If we consider that every call reset to 0 the value of 'last_call_et',
why, in the case of launching the same request by TOAD, shouldn't i see the reset to 0 when the fetches works (because in TOAD during the whole query, which means since the click on "launching query" to the retrieving of data, the value did not reset to 0) ?

When you say
Having said that, I've just run a quick test in SQL*Plus on 11.1.0.6 and 10.2.0.3 to demonstrate this point, and 11g is behaving differently from 10g - in the case where the last_call_et should be growing it stays at zero.
"in the case" : in the case of the v11 or the v10 ?11g
In my case : i'am on a v10.2.0.3 ::: Is there a bug ?Not that I know of.ok. So it is in V11 that you have an incorrect behaviour ....

Jonathan LewisLAST NEWS : we have relaunched the query in SAS and observed that we have the same context of plan in both cases (by SAS en y TOAD) : ALL_ROWS.
Very strange ...
Last question :
Just to be sure : When you talk about "First Rows plan" : it means that the retrieve data are restricted to the first rows encountered
or
it is just the plan of the query which is in "that context" which means that the engine works so although the whole data are retrieved ....

Sort by columns once per session

Hi there, I am using apex 3.1 and I have a report generated by a pl/sql function. There are several columns on which the user might sort. Is it possible to reset the sorting preferences when the user logs in? (like: a process running once per session?)
thx in advance
Edited by: 814932 on 23-Nov-2010 08:00

You can use the <tt>apex_util.remove_sort_preferences</tt> method (although it is a bit of a blunt instrument). See the Admin guide for more information on user preferences.
To run it once per session, code the call as an Application Process with execution point On New Session After Authentication.

How to separate application module instance per user session?

Hi.
How do you separate application module instances per session or per user? I am creating a web application and has created a simple filter that implements Filter.
Thanks in advance.

Hi Frank. Thank you for the reply.
I tried using two browsers. The behavior of each page is very much different when being opened individually. Its like the two pages is sharing the same iterator / data and / or entity object. These two pages were opened to see if one is dependent upon the other. But when I test the same scenario on a different computer, everything works out fine.
Is there a way for me to verify if the sessions are different? and if they are different, is there a way to verify if the application module created a new instance for the other session?

Web module column link to go in detail query is disabled

Hi,
I have a query only module. Once I query the module, it shows list of
matching records. My problem is I am not getting a link in any queried
columns to see the details of selected record.
I don't know which option it will enable it.
Pl. help!! Thanks in advance.

Hi Ingmar,
Implement 'ON_CLICK_EVENT' in the same view where u have ALV. Clicking on the link in the cell using link to action gives you the following information which u can use (pass to other view etc..) -
COLUMN_ID
INDEX
ATTRIBUTE
VALUE
You can read these values and store them in a node.
Create one node in the view by name 'EVENT_PROPERTIES' with attributes 'NAME' and 'VALUE' of type string both and use the below code in on_click_event. Here I am navigating to the next view after clicking the link, you can do whatever u want depending on ur requirement.
DATA: lr_node TYPE REF TO if_wd_context_node,
lt_event_properties TYPE if_models_list_view=>elements_event_properties,
ls_event_properties TYPE if_models_list_view=>element_event_properties.
FIELD-SYMBOLS: <l_value> TYPE ANY.
fill internal table
ls_event_properties-name = 'COLUMN_ID'.
ls_event_properties-value = r_param->column.
APPEND ls_event_properties TO lt_event_properties.
ls_event_properties-name = 'INDEX'.
ls_event_properties-value = r_param->index.
APPEND ls_event_properties TO lt_event_properties.
ls_event_properties-name = 'ATTRIBUTE'.
ls_event_properties-value = r_param->attribute.
APPEND ls_event_properties TO lt_event_properties.
ASSIGN r_param->value->* TO <l_value>.
ls_event_properties-name = 'VALUE'.
ls_event_properties-value = <l_value>.
APPEND ls_event_properties TO lt_event_properties.
navigate to context node EVENT_PROPERTIES
lr_node = wd_context->get_child_node( 'EVENT_PROPERTIES' ).

Does anyone know how Oracle Forms (11g) sets the V$SESSION.MODULE value?

Hi,
Older versions of forms required explicit calls to dbms_application_info package to set the name of the forms module (or other useful diagnostic info made visible on the database via v$session module, action and client_info).
It seems that the application we currently manage (third party vendor) sets this, too. But I cannot find any call to DBMS_APPLICATION_INFO in the source fmb, pll, olb or any database package code called from the forms sessions.
Can anybody confirm my suspicion that the V$SESSION.MODULE attribute is now being set by low-level Forms library code, independently of application code?
If so, it's a great feature, I just want peace of mind! I've searched google, this forum and Oracle Support site for any reference to such a behaviour, but struck out.
Thanks,
Andrew

Oops. Next time I'll take off the 90day limit on search history.
For others: In 11G the MODULE column of V$SESSION is updated with the Forms module name. [Oracle Support ID 1413688.1]
Cheers,
Andrew

Find database name of sessions over database link

Hi,
I have a database in which i can see a few sessions which are connected to this database from one of my server which is hosting 2 databases. Now if i query v$session on my local database, i can only find the host name in program and module column of v$session view. How can i find out that from which database these sessions are established because i have two databases on that remote host from where these sessions are estableshed.
Thanks
Salman

only way is if i have set the client info.alternatively application info.
I've never tried the following, but perhaps using different LISTENER or port could be used as a differentiator.
Keep in mind that what the local DB server "knows" is it serviced some connection request from remote client.
Local DB server knows little to nothing about any remote DB masquerading as a client connection.
This is an application issue not Oracle RDBMS issue.
