Storage Standby Inconsistent Behaviour (hdparm -S)

Well hi folks, I have a bunch of ata/sata drives.
-M acoustic = not supported
-B APM_level = not supported
-k DIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device
If i apply -S 60 (5 min) it works out very well.
But any value higher than 120 won't spin down the drives at all.
Apparently i'd like to set 240 (20 min). 60 is too low.
I've tried hdparm -K 1 as well as smartctl -s off --offlineaouto=off --saveauto=on
With mounted partitions or not. With systemd oneshot unit or
the udev rule mentioned in the wiki. Fstab commit=600 or 1200.
Or should i apply these commands in any specific order?
On top of that, i have a feeling they used to work with -S 120.
But on a random basis. Totally arbitrary behaviour.
I use hddtemp /dev/sd? to check the state.
Still i can't pin point the reason why. At this point it seems incomprehensible to me.
Where should i look next?

Now there's been some development. If i leave the freshly booted sys alone,
standby performs as expected, apparently.
I have some reasons to beleive all this mess caused by that mf Wine.
winecfg alone wakes up all standby storages immediately for no f reason.
i do use wine all the time for my charting platform.
but this doesn't explain why the hdd standby is being prevented.

ECC 6.0 VERSION UPGRADE - INCONSISTENCY BEHAVIOUR -MM - Reg

Hai,
We are in the process of ECC 6.O upgrade from ECC 5.0,
we started the CT1/ CT2 testing and found the following error.
While inwarding Material against Subcontracting purchase order / S.L.Agreement ,
The system shows the error message of CHALLEN MATERIAL IS DIFFRENT FROM MATERIAL DOCUMENT , during GR
note :- for the same material , same p.o , some times systems allows for GR & some times gives above error message.
if i try with some other login , the behaviourseems to be same as my login
Can anyone tell this why this inconsistency behaviour of system during GR for sub contracting item..
Regards,

go to SE38, here type the program RM07CUFA,
click on execute... type ur mov type 541... here make the purchase order field from display to optional..
this will effected for new subcontracting scenerio....

Inconsistent Behaviour on executing Xquery on the container....

I need some of the suggestions on the following BDB issue. Here I written the code to create the container, load the .xml file in to it with doc_id and opens the allready existing container. Here I am seeing inconsistent behaviour.
Following are the Steps I followed...
1. Created DbEnv class object .
2. Opened the DbEnv using open methode with flags "DB_CREATE | DB_INIT_MPOOL".
3. Created XmlManager class object with the flags "DBXML_ADOPT_DBENV | DBXML_ALLOW_AUTO_OPEN".
Rest of the steps are mentioned in the code fragment..
Class Definition is as follows...
#include <dbxml/DbXml.hpp>
using namespace DbXml;
using namespace std;
class BDBObject // Singleton class
public:
static BDBObject* instance();
bool open_xml();
bool close_xml();
bool execute_xquery(const string & exp, string & response);
~BDBObject();
private:
BDBObject();
static BDBObject* m_singletonObject;
XmlManager *m_xmlManager;
DbEnv *m_bdbEnv;
XmlUpdateContext m_xmlUpdateContext;
XmlQueryContext m_xmlQcontext;
XmlContainer m_necbContainer;
XmlContainer m_necbXmlContainer;
bool BDBObject::open(bool flagEnabled)
-------------- < code fragment for first 3 steps mentioned above> -----------------
try{
string containerName = "container1.dbxml";
if(m_xmlManager -> existsContainer(containerName))
[b]m_necbContainer = m_xmlManager -> openContainer(containerName); // Opening allready existing container
else
return false;
if(flagEnabled)
XmlUpdateContext updateContext = m_xmlManager -> createUpdateContext();
m_necbXmlContainer = m_xmlManager -> createContainer("container2.dbxml");
XmlInputStream *fileStream = m_xmlManager -> createLocalFileInputStream(filePath);
m_necbXmlContainer.putDocument(fileDocId, fileStream, updateContext, 0);
}// End of Try block...
catch (XmlException &xe)
cout<<"XmlException: "<<xe.what()<<endl;
return false;
return true;
}// End of function
bool BDBObject::execute_Xquery(const string & sExp, string & response);
if(NULL == m_xmlManager)
return false;
XmlContainer *bdbContainer = NULL;
if(flagEnabled)
bdbContainer = &m_necbXmlContainer;
else
bdbContainer = &m_necbContainer;
if(bdbContainer == NULL)
return false;
try{
XmlQueryContext xmlQcontext = m_xmlManager->createQueryContext();
string containerName = bdbContainer -> getName();
m_xmlQcontext.setDefaultCollection(containerName);
XmlQueryExpression xmlQExp;
if(flagEnabled)
xmlQExp = m_xmlManager -> prepare(sExp, xmlQcontext);
XmlResults bdbResult = xmlQExp.execute(xmlQcontext);
XmlValue bdbValue;
while(bdbResult.next(bdbValue))
response = response + bdbValue.asString();
}// End of Try block..
catch (XmlException &xe)
cout<<" XML Exception: "<<xe.what()<<endl;
return false;
return true;
}// End of function
<---------------- Application ----------------->
main()
cout<< "In Application "<<endl;
bool flagEnabled = false;
BDBObject *obj = BDBObject::instance(); // Singleton Object Creation
obj -> open(false);
string xquery("");
if(flagEnabled)
xquery = "declare namespace HHP=\"HHP\";
let $n := doc('container1.dbxml/<corressponding docId>')//HHP:hapCageTable
return ($n);"
else
xquery = "declare namespace HHP=\"HHP\";
let $n := doc('container2.dbxml/<corressponding docId>')//HHP:hapCageTable
return ($n);"
string response;
obj -> execute_xquery(xquery, response);
---------- END -------
Here when I make flagEnabled as false in the application & then compiled.. After execution of the application, I had got expected output.
Use cases which i tested the application in sequence are...
1. I make flagEnabled as false in the application & then compiled.. After execution of the application, I had got expected output.
2. I make flagEnabled as true in the application & then compiled... After execution of the application, I had got expected output.
3. I make flagEnabled as false in the application & then compiled... After execution of the application, I had got exception in the BDBObject::execute_xquery() function at the line "xmlQExp = m_xmlManager -> prepare(sExp, xmlQcontext);" and shows the exception as "Error: No such file or directory".
4. If I execute once again the previous use case, then it works.
5. Now I re-executed the use case 2, I had got expected output.
6. Now I re-executed the use case 1, Here I am able to see the execption in BDBObject::open function at line "m_necbContainer = m_xmlManager -> openContainer(containerName);" and shows the exception as "Error: container1.dbxml: container file not found, or not a container".
Please let me know some suggestions to proceed further on this issue..
Thanks in Advance,
Regards,
Sravan.

Sorry let me explain it clearly.....
Input plain xml file:
<bookstore>
<book>
<title>ALSB</tile>
<price>100</price>
</book>
</bookstore>
As we know $body points to root element of above input xml file
1) My xpath/Xquery condition is --> data($body/book/price)>30 than I validated and tested with above xml input it returns true to me so I saved and activated my proxy.
2) Now next step let me test proxy from proxy test screen for above input xml file, I clicked on test icon and inputted above xml file. But myxpath/Xquery condition in proxy fails and it goes to else condition.
The strange part is, if I change my input file to
<book>
<title>ALSB</tile>
<price>100</price>
</book>
Than above condition return true, why this is behaving like this

Storage bucket inconsistency

I am getting an error message, when i am running a LC consistency. The error says" storage bucket profile start times in LC are inconsistent with those in the data base. I try to create the time series as per the storage bucket profile and try to recreate the POB and PA. None of them fixed the problem. Did any body come accross the problem. Any help is appreciated.
thx

Hi Jeff,
Try the below reports (transactions)
1) /SAPAPO/PSTRUCONS

Storage Unit Inconsistency!!

Dear Experts,
One background job in SAP which runs every 10mins got canceled because the storage unit was inconsistent with the transfer order data. I am not able to find the cause of this inconsistency of storage unit!!
Any ideas??

Can I know what kind of error (details of inconsistencies) you are getting?

Point4D.Multiply inconsistent behaviour with NaN values

I've noticed some peculiar behaviour with System.Windows.Media.Media3D.Point4d.Mutiply when used with NaN values.
The following assumes that I expect that 0 * NaN should result in 0. There is an argument against that logic, but that is not the point here.
I have a 4x4 matrix defined, in the case that it is an Identity matrix and there is a NaN component in the vector, I would like to get some defined vector output where it is possible to calculate the component.
E.g. (1,2,NaN,4) * (Identity Matrix) = (1,2,NaN,4).
I was caught out for a while:
By stepping through using the debugger gives the output I want (1,2,NaN,4).
But allowing the debug code to run through uninterrupted gives the result (NaN, NaN, Nan, Nan).
There is a slightly surprising workaround: - using Matrix.IsIdentity seems to trigger the result I want
If I use the default Matrix constructor instead of a manually created one (normally created elsewhere in code), there is no problem.
Can anyone explain this inconsistency?
Simple C# console demo:
using System;
using System.Windows.Media.Media3D;
namespace TestNan
class Program
static void Main(string[] args)
Point4D testPoint = new Point4D(1.0, 2.0, Double.NaN, 4.0);
Matrix3D testMatrix = new Matrix3D(1.0, 0.0, 0.0, 0.0,
0.0, 1.0, 0.0, 0.0,
0.0, 0.0, 1.0, 0.0,
0.0, 0.0, 0.0, 1.0);
var testResult1 = Point4D.Multiply(testPoint, testMatrix);
Console.WriteLine(testResult1.ToString());// NaN,NaN,NaN,NaN
var b = testMatrix.IsIdentity;
var testResult2 = Point4D.Multiply(testPoint, testMatrix);
Console.WriteLine(testResult2.ToString());// 1, 2, NaN, 4
Console.ReadKey();

>>Can anyone explain this inconsistency?
The Matrix3D class has an internal boolean flag that it uses to determine if the matrix is actually an identity matrix and this flag is not set when you create a Matrix3D object using the constructor that takes the 16 double values despite the fact that
you are actually creating an identity matrix (the flag is then eventually set when you access the IsIdentity property).
If you use the Matrix3D.Identity static property, the flag will get set to the correct value immediately and the results will be the expected:
static void Main(string[] args)
Point4D testPoint = new Point4D(1.0, 2.0, Double.NaN, 4.0);
Matrix3D testMatrix = Matrix3D.Identity;
var testResult1 = Point4D.Multiply(testPoint, testMatrix);
Console.WriteLine(testResult1.ToString());
var b = testMatrix.IsIdentity;
var testResult2 = Point4D.Multiply(testPoint, testMatrix);
Console.WriteLine(testResult2.ToString());// 1, 2, NaN, 4
Console.ReadKey();
Hope that helps.

SSRS PDF report inconsistent behaviour

Hi,
We are using SSRS reports in out project. In one of the reports we are facing a weird behaviour of PDF report. The report has few legends at the start and then the table containing the data starts.
If the report has 25-28 records then the table starts from Page 2 instead of Page1. The corresponding HTML report is working fine.
If the report has less then 25 records, table starts correctly from Page 1.
If the reports has more than 30 records, then also the table starts correctly from Page1 and remaining records at Page2.
Does anybody has idea why PDF reports starts displaying the table from Page 2?

PDF reports in SSRS are generated with physical dimensions of the page and HTML are generated as logical. So if any of the rows in your first page or header is wider than a A4 size paper then part of the row will be moved to the next page. Keeping
this in mind can you recheck the issue. The fact about 30 rows being on one page and 25-30 rows being moved to another might just be a conincidence. Maybe one of the records in the 25-30 set is wider than the other records. Could you please recheck and confirm?

Inconsistent behaviour in Java 1.2 and 1.3 version

Hi Where can I find the complete list of methods and classes which are not depricated but have different behaviour in Java1.2 and 1.3 version, like one method is nextToken(String) of StringTokenizer class.

Thing like this are likely to be found in the release notes for each version. The release notes of 1.3 are @ http://java.sun.com/j2se/1.3/relnotes.html

DBMS_RANDOM inconsistent behaviour ?

Hi:
I have an issue with DBMS_RANDOM on 9.2.0.6
#### TEST CASE #####
create table t1 (col1 number);
insert into t1 values ('1');
insert into t1 values ('2');
insert into t1 values ('3');
-- ## QUERY1
select rnd1, rnd1, col1 from (select * from (select dbms_random.string('U',5)
rnd1,col1 from t1));
RND1 RND1 COL1
EVJMP CZGSY 1 <- the two occurrences of RND are different
WHZTP TEJBP 2
HOMYO DQVKG 3
-- ## QUERY2
select rnd1, rnd1, col1 from (select * from (select dbms_random.string('U',5)
rnd1,col1 from t1 where rownum < 99));
RND1 RND1 COL1
DGMSG DGMSG 1 <- the two occurrences of RND are equal
MUEFU MUEFU 2
UAKLH UAKLH 3
########## 
I believe that query1 behaves wrong, I cannot reference the random value... while I believe query2 is correct. 
My goal is to have multiple occurrences of rnd1 field share the same value, without applying filtering with rownum. 
Is this the intended behaviour? 
Any idea on how to make query1 behave as query2?

Very odd this is what you select returns on 9.2.0.6
SQL> select * from (select * from (select dbms_random.string('U',5)
2 rnd1,dbms_random.string('U',5)rnd2, col1 from t1 where rownum < 99))

AOPLL DHRHE 1
XPACR ADOUK 2

Inconsistent behaviour of Sybase SQL anywhere update column trigger

Hi, all
I am not sure where to post this issue, since I could not find a forum for Sybase SQL anywhere.
The problem is as follows:
The definition of the update column trigger in help is this:
UPDATE OF column-list
Invokes the trigger whenever a row of the associated table is updated such
that a column in the column-list is
modified.
However, there are cases when the triggers are launched even when the columns are not modified (ie the same exact value is in the both OLD and NEW row)
This happens on BEFORE triggers, never saw it happening on AFTER.
Ways to replicate the problem:
1. Define a before trigger, which fires on update of a specific column in any table.
2. Run an sql which says "update table1 set column1 = column1 where ... "
3. You will see that trigger fires, even though it is not supposed to.
Is this an expected behaviour on "BEFORE" triggers?
Arcady

If this were a sql server question, then I could tell you that this is by design. A trigger will be executed regardless of the number of rows affected (including zero) and regardless of whether any column in any of the affected rows was changed. I will also point out that PB was designed to work within this design by the inclusion of the [where clause for update/delete] option in the update properties of the datawindow. The idea is that you avoid actual row updates (in the table) where nothing has actually changed (and it also supports collision avoidance).
Based on the history, I would assume that Sybase works exactly the same.

SAP Screen Personas 3.0 - Inconsistent behaviours and features after installation

Hi,
Our company installed SAP Screen Presonas 3.0. We followed up Personas installation OSS notes and instalaltion check list.
The Personas Health Check displays no issue (see below).
However, we do get inconsistent behaviors from Personas 3.0:
- Assign background button, Stretch button, Upload button don't work
- Unassign image isn't possible
- Fill color button and Bold icon don't work with a theme assigned to the transaction
- Images and buttons aren't aligned when a flavor is displayed (compared to when a flavor is edited)
- the link to personas via Chrome through https doens't work any more (after update of kernel at patch 22).
Do you have any idea ?
Thanks,
Christophe

Some of those, particularly the image issues, are familiar. Others not - I've never had issues with Chrome, for example. Does https work in other browsers? That would be very strange. Not working in all browsers sounds like a kernel installation issue.
There's a newer kernel now - pl24 was released just a day or two ago. There should be a new Personas client note tomorrow. I suggest applying both of those to see if any of your issues go away. If not, ask here again, but also create OSS messages for them to make sure they don't get lost.

Inconsistent behaviour of the response

Hi Everyone,
We have a very weird problem here. Our application is a servlet based app using iPlanet Enterprise 4.0 application server. The servlet response acts very inconsistent when we try to change the response type from text/html to something else in the application(to res.setContentType("application/vnd.ms-excel") for example). Sometimes it works but most of the time instead of opening results in MS Excel, output is being rendered as an HTML.
Does anyone have any suggestions?
Any help will be greatly appreciated.
Thanks,
YM

First of all I am setting the response type by
calling
res.setResponseType("application/vnd.ms-excel");Then I call some classes to query the database and
return the ResultSet, which I then pass to the
formatting classes to create an HTML page and write
the ResultSet in the form of an HTML table inside the
page. After that's been done, I get PrintWriter out
of the response and writing the page by calling
PrintWriter out = res.getWriter();
out.print(formatted_HTML_page);
Sorry, I meant res.setContentType

Annoying inconsistent behaviour

On many edit pages, there is a Apply Changes button and Next (>) and Previous (<) buttons
On some pages, the next/previous buttons apply changes to the current page and then go the next/previous page.
On some pages, clicking the next/previous button pops up a Javascript box 'Are you sure you want to lose your changes?' without giving me an option to Save and continue.
On some pages, it silently discards my changes and moves to the next/previous page!
Can this please be fixed so the behaviour is intuitive and consistent?
Thanks

1. The Process edit page (4000:4312). If I make changes to my process code and click the 'Next' button, it silently discards my changes
2. Item edit page (4000:4311) This has a good interface. The next/previous buttons apply changes and then go to the next/previous page
3. I cant remember now which page pops up the Javascript box. But there is definitely a page in the App Builder which does this.
Thanks

Default Value in Formula Variable - Inconsistent behaviour

Hi,
I am facing a very strange issue in a formula variable.
I had created three formula variables with default values and the user (Power user who has the Bex access) was able to change the default value themselves for two of these variables.
Now he wants to change all the three, so I have tried to check the issue and changed all the three for testing purpose.
Now, he is unable to change any of them!!! Sad, now I cant even say that "You dont have the Auth to do so"
Any clue? Anyone has faced similar issue.
Any thoughts are highy welcome! Suddenly users wants to get this one URGENTLY, usually he used to access the report once in month. Now he wants to use the same once in half an hour
We are on BI 7.0 with SP 24
Any thoughts PLS

hi,
probably you can refer to SAP Note 1413030 - SAPBWNews NW 7.x BW Add-On Frontend Patch 1300 - GUI 7.10 or maybe SAP Note 1294382 - SAPBINews NW7.0 BI Add-On Frontend SP900 - GUI 7.1 that might help you in sorting out your problem, plus you can buy more time from the user as well

Stored Credentials not always enterprise - Inconsistent behaviour

Ok, so we've got a remote desktop group setup, Reasonably standard deployment with a couple of shared components, for the most part it works. I'll get some more info on the deployment tomorrow, here's a basic summary of the problem we're facing.
Several users are prompted for Outlook Credentials every time they log back into their sessions. Credentials Manager shows that the Persistence level for the users with this problem is Logon Session, not Enterprise as it is on all the other users without
a problem.
I immediately blamed some funky Group Policy as it wasn't occurring to all users, but when it did apply to a user... it stuck & nothing I can change will allow it to store.
Things I've tried:
Stripping all group policy's away from the User Accounts.
Recreating the User Account. (Delete, Create)
Delete all reference to the User Account from the Session Host (Registry, Local User, Roaming Profile, Documents - everything I could find!)
Tried another Session Host (Problem follows to the new session host.)
Cloning the User Account. (The Clone works perfectly!!)
Granting the user account full domain & local administrator.
As a work around I can simply go into Credentials Manager & store the credentials as Enterprise, which sticks... but that's not a workable solution for 30+ users that change their own passwords from time to time. I'm out of ideas of what to try,
anyone come across this kind of thing before?
My hunch is it's something nested within AD that's not deleted with user accounts... but I'm pulling at straws.
