Need clarifications regarding APEX_PUBLIC_USER

Hello all,
Apex 3.0 on 10g
'am aware that APEX_PUBLIC_USER is the one used by the apex applications to get the stuff from the database.
I have noticed that in v$session there do exist the apex_public_user even if i logout from the apex.
In my production i have found apex_public_user with last_call_et greater than 7 hrs
and also when i tried to drop a package from the apex sql window, it hangs and doing the same from sql*plus from system account makes the session hang, which i will need to kill later. What could be the reason for the session to get stuckup??
Thank you,
J J

Yea, today i had to bounce my DB for some reason and there were no connections from the APEX_PUBLIC_USER and i could drop the package.
Is there anyway to close those sessions from the oracle HTTP server once they are done with the job than letting them lingering around?
Will APEX use these existing sessions like a connection pooling?
TIA,
JJ

Need clarification regarding the test cable-diagnostics tdr command

Hello,
I've read about the test cable-diagnostics tdr command but I need clarification on the examples listed below to make sure that I am providing the right answer to my co-workers.
Example 1:
CXXX7SW17#show cable-diagnostic tdr int g0/20
TDR test last run on: July 16 10:23:00
Interface Speed Local pair Pair length        Remote pair Pair status
Gi0/20    auto Pair A     N/A                        N/A                Normal
                       Pair B     72   +/- 10 meters N/A                Open
                       Pair C     75   +/- 10 meters N/A                Short/Crosstalk
                       Pair D     74   +/- 10 meters N/A                Short/Crosstalk
Does this example mean that there's a cable length issue in the line which is causing the device that it's connected to not to work properly?
Example 2:
CXXX2SW140#show cable-diagnostics tdr int g0/21
TDR test last run on: July 16 09:16:22
Interface Speed Local pair Pair length        Remote pair Pair status
Gi0/21    100M Pair A     N/A                      Pair A           Normal
                          Pair B     N/A                      Pair B           Normal
                          Pair C     N/A                     Pair C           Normal
                          Pair D     N/A                     Pair D           Normal
Does this example state that the cable line is okay for use?
Example 3:
CXXX1SW19#show cable-diagnostics tdr int g0/22
TDR test last run on: July 16 06:36:53
Interface Speed Local pair Pair length            Remote pair Pair status
Gi0/22   auto    Pair A       1    +/- 10 meters N/A               Open
                          Pair B     39   +/- 10 meters   N/A               Open
                          Pair C     72   +/- 10 meters   N/A               Open
                          Pair D     1    +/- 10 meters    N/A              Open
Does this example mean that there isn't a device connected on the other end? No pin-contact?
Thank you very much for any help you could provide.

I found this article here at supportforums that seemed like the best explanation I've read so far for TDR info.
Hope that helps.

Needs Clarification Regarding Segments and Datafiles

Hi,
I want clarification regarding Segments, Datafiles and extents.
As we know that A segment is made of one or more extents and extents are composed of one or more datablocks in the HD.
Since all data are store in Datafiles which are composed of extents and datablocks. I want to know weather a table(Segment) can span to multiple datafiles or in a sigle datafile.

Need clarification regarding select query

Hi,
I need a little clarification regrding a Select senario
I want to select data from table which have been minupulated between a certian date like between 1-DEC-10 to 31-DEC-10 and note that table does not have any time/date column. I've applied the following query to do this.
select * from TABLE_NAME where sysdate between to_date('01-DEC-10') AND to_date('31-DEC-10');
Would it work fine because I've tried it against a table and it returned me nothing however DML occur between time period.

Needs Clarification Regarding Tablespace

Hello,
I'm using Oracle 10g DB and I want to know weather to creating database from DBCA automatically create a tablespace for that database or we have to create manually.
if it create automatically then how can we retrive information about that database.
Looking for Reply
Regards,
D.Abbasi

When you create database using DBCA you can choose tempalte, in the template there tablespaces defined, the tablespaces that will be created depends on the tamplate you choose, and if you installed sample schema's.
Every database created need to have several system tablespaces.
You can retrive all of database tablespaces using :
select name from v$tablepsace;

Need Clarification Regarding Structural Authorization

Hi Gurus,
When you do need to implement Structural Authorization? How do you know when you don't need it?
I'm currently on an ECC6 implementation project and was informed that we do not need to implement it even though we are implementing the HR organization structure along with ESS and MSS.
Your inputs are highly appreciated.

for one it can be useful to implement structural authorizations when you want to restrict not only on the enterprise structure (e.g. personnel area, employee group etc.) but also on organizational atributes (position, org. units and the likes).
this decision is purely based on the requirement of your company's security demands.
as for your second question, I assume that there is a misunderstanding of terms. HR roles as such are the same as non-HR roles in so far that they can be assigned to the user directly through SU01 or PFCG.
the advantage of having an org. structure is that you may also assign the roles through this structure as well. this in itself has nothing to do with whether you would want to implement structural athorizations.
I hope to have clarified things a litlle for you.

Need clarification regarding Work status rule

Hi All,
I have a work state "Submitted" which is controlled by "owner".
My work status is driven by following dimensions in the application:
u2022Entity - Owner dimension
u2022Category
u2022Time
Entity hierarchy is as follows : A
|____B
|____C
Now considering that user is owner of member "A", I set the work status to "Submitted". (Note: B and C does not have any owner)
It gives error "controlled by rule has been violated".
On the other side, one of the document tells states that "If the user is acting as an owner and the selected member has no parent, the user also acts as a manager (top hierarchy), they can select a work status controlled by "Owner", "Manager" or "Both"".
Going by this rule, in the scenario which i have explained above, it should set the work status as "submitted". But it is throwing error.
Kindly clarify if my understanding is wrong.

Hi,
The problem is arising because as per the setup, only the owner can change the work state to submitted. However, there are no owners for the child members.
You can try changing the setting to manager. If you login as owner of A, then you will be able to change the work state of A (since you are your own manager because A is the top node) and you will be able to change B and C also (since you are the manager).
Alternatively, you need to maintain the same user as the owner of B and C.
You have rightly indicated the statement "If the user is acting as an owner and the selected member has no parent, the user also acts as a manager (top hierarchy), they can select a work status controlled by "Owner", "Manager" or "Both"".
However, if you take a look at this statement, this is valid if the setting is manager. But in your case, the setting is owner. And there are no owners of the children.
Hope this helps.

I need clarification regarding REFERENCE TYPES and CASTING.

Hello all,
I'm taking a course on the fundamental of JAVA. Everything's been going smoothly until I slammed into the the concept of CASTING and REFERENCE TYPES. Flat--out == I DON'T GET IT?
I'm having trouble with...
CONVERTING REFERENCE TYPES
CASTING BETWEEN REFERENCE TYPES
WORKING WITH REFERENCE TYPES
I understand what's happening from an academic vantage point. I just don't understand why you'd want to convert REFERENCE TYPES? What would be an application of such an exercise?
1. What IS a REFERENCE TYPE -- exactly?
a. what are we referencing?
b. type? type of what??
for example... why would you want to do a widening conversion, a conversion of the hierarchy tree?
I understand the concept of OBJECTS, CLASSES, METHODS and CONSTRUCTORS so far...
I think it's the terminology that's screwing my up.
Thanks,
Alex

ok... wow, thanks J.
So--in a nutshell-- we're making it so that different
objects:
ie,. ford(), chevy(), honda(), lotus() and
dealers()... so and so forth()...
all share the resources(for lack of a better word) of
the Auto Class? because all of those auto brand
objects and one redically different object can be
unrelated, correct?Um, yes and no.
I just ran with the example you had, but that probably included too many concepts and they got muddied up.
Yes, Chevy, Ford etc. all share the characteristics of Auto, since they're all subclasses. But that's just inheritance, and has nothing to do with casting.
A "reference type" can loosely be described as a variable that refers to an object. (Constrasted with "primitive types" which are int, char, float, etc. and don't refer to objects--they just hold values.)
Casting just tells the compiler that even though as far as it knows you only have a reference to some superclass, the object that reference points to will in fact be an instance of a subclass, and so treat it as such (e.g., we can now call methods that the subclass has that the superclass lacks).
(You can also cast primitives, but one thing at a time.)
So let's say you have class A (which extends object) and B extends A.
A a = new B();
B b = a; // won't compile. compiler sees the "A a" on the left of the =, not "new B()" on the right.
B b = (B)a; // works because we're telling the compiler, "Dude, I'm seriously. This is a B.
Note that if we had done new A() instead of new B(), it would still compile--the compiler would trust us. But at runtime, we'd get a ClassCastException, since we wouldn't actually have a B object.

Need Clarification On Internal tables in Start Routine

Hi,
I have intenal table some IT_A which deletes the requests which are populated in to it.
Now I need to populate requests into IT_A from another internal table like IT_B which are of different structure.
I have three fields in common in both internal tables like RNR,Timestamp n SID with different field names
I Need Clarification that if i move the contents of the three fields to IT_A from IT_B by spcifying these three fields.Will the internal table IT_A deletes the Requests?
Thanks,
Sriram.

Hi Sriram,
As mentioned IT_A deleted the request loaded into it.
if you move the contents of the three fields to IT_A from IT_B by spcifying the three fields after the deletion step for internal table IT_A takes place then it wont get deleted.
But it would be deleted if the the contents are moved before the deletion step takes place

Hi,
Calculated Property in webdynpro is required when you want to handle node context attribute programmatically.
When you say Context Attribute as True, it generates two methods, Setter and Getter Method for that attribute.
In getter method you will be getting one element it is the context node, where you created attribute. These methods will be called automatically.

Hi Baskar,
Yes, its feasible.
However you need to map your 0CALMONTH to your 0CALQUARTER, then write this routine.
DATA : MY_VARSPMON(6),MY_VARYEAR(4),MY_VARMON(2),MY_VARQUARTER TYPE /BI0/OICALQUARTER.
    MY_VARSPMON = SOURCE_FIELDS-SPMON.
    MY_VARYEAR = MY_VARSPMON+0(4).
    MY_VARMON = MY_VARSPMON+4(2).
    CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
      EXPORTING
        INPUT = MY_VARMON
      IMPORTING
        OUTPUT = MY_VARMON.
    IF MY_VARMON = '01' OR MY_VARMON = '02' OR MY_VARMON = '03'. MY_VARYEAR = MY_VARYEAR - 1.
      CONCATENATE MY_VARYEAR '2' INTO MY_VARQUARTER.
    ELSEIF MY_VARMON = '04' OR MY_VARMON = '05' OR MY_VARMON = '06'.
      CONCATENATE MY_VARYEAR '3' INTO MY_VARQUARTER.
    ELSEIF MY_VARMON = '07' OR MY_VARMON = '08' OR MY_VARMON = '09'.
      CONCATENATE MY_VARYEAR '4' INTO MY_VARQUARTER.
    ELSEIF MY_VARMON = '10' OR MY_VARMON = '11' OR MY_VARMON = '12'.
      CONCATENATE MY_VARYEAR '1' INTO MY_VARQUARTER.
    ENDIF.
    RESULT = MY_VARQUARTER.
I don't guess there's any changes in particular; but you may considerably change as per requirements in the ABAP logic.

Some clarifications regarding Aironet settings

Hi,
i need some clarifications regarding configuring Aironet stand-alone AP (in this case AIR-LAP1131AG).
Under Security->SSID Manager:
what is the purpose of Network ID?
Under Guest Mode/Infrastructure SSID Settings - what is the purpose of Set Infrastructure SSID?
and Force Infrastructure Devices to associate only to this SSID?
Cheers,

Assign a Service Set Identifier (SSID) to each VLAN configured on the AP. SSIDs enable endpoints to select the wireless VLAN they will use for sending and receiving traffic. These wireless VLANs and SSIDs map to wired VLANs. For voice endpoints, this mapping ensures priority queuing treatment and access to the voice VLAN on the wired network

Need inputs regarding the dvd drive on primary ide channel.

Specs:
Motherboard: MSI P35 Neo3 (MS-7935 1.0)
CPU: Intel Core2 Duo E6550
Memory: Team Elite DDR2800 (2x1GB Dual Channel)
Hard drive: Seagate Barracuda 7200.11 500GB 32MB Cache (SATA)
Optical drive: LG GSA-H55L (IDE only) Firmware version 1.02
Graphics card: Gecube HD3870
Chipset: Intel P35/G33/G31 (Rev. A2)
Southbridge: Intel 82801IB (ICH9)
LPCIO: Fintek F71882F
BIOS: AMI V1.1 (11/07/2007)
Hello,
Almost all new motherboards today only have a primary ide channel and the rest are SATA.
I need inputs regarding the dvd drive which is shown in device manager as located on the primary ide channel while the hard drive is located on the secondary channel. Because I would like to update the dvd drive to the latest firmware (version 1.06; to be able to recognize more blank media) but the LG site recommends that the drive (dvd) be located on the secondary ide channel.
I already tried to uninstall every channel from the device manager but all would still be the same after reboot, dvd drive on primary, hard drive on secondary.
Current ide mode in BIOS is set to AHCI+IDE mode, DMA modes are fine (UDMA4 for dvd, UDMA5 for hard drive), boot sequence (1st=HD, 2nd=DVD, 3rd=Floppy drive)
Tried switching to IDE mode only in BIOS but would not detect the optical drive. Never tried RAID+IDE mode since I only have a single hard drive.
I'm not sure but if I try to update the firmware, it might instead try to update the hard drive's firmware instead of the optical drive and make the hard drive unusable.
I would like to know if anybody with this same situation was able to successfully update the optical drive's firmware or is there some way to place the optical drive on the secondary ide channel and the hard drive on primary for me to follow and replicate the process.
Thank you for any replies.

Thanks sir NovJoe for the reply.
Just received the solution from another forum where I posted the same problem.
They said that the flash program for the firmware will detect the drive on its own and would not flash other devices except the optical drive itself. So its pretty safe, and I can confirm this since I just flashed my ODD a little over a while ago and everything went fine. No errors.
Though I'm speaking for the brand of ODD I own and may be different for other brands so take precautions as well. It may be different for the others.
