Label menu names missing

Hi friends,
I've got a requirement for preparing dashboards, where i have to use label menu for showing different units data using bar charts.
so when i am giving those unit names(18 units) for label menu list, label names on dashboards are missing i.e are appearing partially in menu.
in clear
if unit name is: network -> netwo. i think these names are missing partially because of label size. i tried to maximise(width) of labels buts its not working.
so what should i do to get complete names on label menu for all units.
please assist me in this.....
thanks
ram

Hi Rambabu,
You can change its Orientation from Horizontal to Vertical from GENERAL tab of its Properties.
If you don't want to change orientation then you can use 2 Horizontal Label Based Menu to adjust your all tabs by keeping half Units in first label menu and other half Units in second label menu..

Index allocation is missing when creating new index

Hi,
By trying to move away from TOAD I have installed SQL Developer (.
Now, I noticed, that there is no way to define tablespace allocation for index when creating it via SQL Developer. Is this correct?
Thanks
OS: Windows XP
Oracle: 10g R2
SQL Developer: 1.1.0.23

You're right. Also editing an existing index, the dialog doesn't display the current values, it just defaults out.

JSlider randomly missing tick labels

Hello everyone,
I am having a problem with JSliders. I have an application that has several JSliders throughout. They are vertical, min=100 and max=1000, with major ticks every 100, and minor ticks every 25, and the ticks and labels are painted.
I have noticed that out of say 10 such sliders in my application, perhaps one or two sliders are randomly missing some ticks. For example, the labels will read 100, 200, 300, 400, 500, 600, 700, 900, 1000 (with the 800 just missing). The space for the text is there, but no text.
As I mentioned, this doesn't always occur. It occurs perhaps on one or two sliders out of 10 every time I start the application. So this would seem to me to be related to a threading issue.
Here is the constructor that creates the panel that has the JSlider in it:
 try{
 SwingUtilities.invokeAndWait( new Runnable(){ public void run(){
 // INIT GUI & CUSTOM INIT
 initComponents();
 depthJSlider.putClientProperty("JSlider.isFilled", Boolean.TRUE);
 catch(Exception e){ Util.handleExceptionNoRestart("Error building Log Table", e); }
Here is initComponents() which actually does the work:
 private void initComponents() {
 depthJSlider = new javax.swing.JSlider();
 depthJSlider.setMajorTickSpacing(100);
 depthJSlider.setMaximum(1000);
 depthJSlider.setMinimum(100);
 depthJSlider.setMinorTickSpacing(25);
 depthJSlider.setOrientation(javax.swing.JSlider.VERTICAL);
 depthJSlider.setPaintLabels(true);
 depthJSlider.setPaintTicks(true);
 depthJSlider.setSnapToTicks(true);
 depthJSlider.setToolTipText("<html>\nEvent Log Depth Slider \nThis slider allows you to specify the maximum number of visible\
events \nwhen the \"Refresh Log\" or \"Start Auto-refresh\" buttons are pressed.</html>");
 depthJSlider.setMaximumSize(null);
 depthJSlider.setMinimumSize(null);
 depthJSlider.setPreferredSize(null);
 gridBagConstraints = new java.awt.GridBagConstraints();
 gridBagConstraints.gridx = 0;
 gridBagConstraints.gridy = 0;
 gridBagConstraints.fill = java.awt.GridBagConstraints.VERTICAL;
 gridBagConstraints.weighty = 1.0;
 gridBagConstraints.insets = new java.awt.Insets(5, 5, 5, 10);
 tableJPanel.add(depthJSlider, gridBagConstraints);
 }Does anyone have any ideas at all why some of the labels might be missing?
(Please drop a line to [email protected] if you have any thoughts!)
Sincerely,
Ian

Missing 'Add Custom Label' button again

A mate and I both have an iphone 4, same firmware i.e. 6.1.3 and as far as i can see all settings are the same. However when entering the same new contact on my phone I have at the bottom of the 'select phone type label' screen an add a 'Custom Label' button, the list of phone types labels on mine are 'Mobile, iPhone, Home, Work, Main, Home Fax, Work Fax, Pager, Other' On my mates his list is 'Home, work, home fax, work fax, pager, assistant, car, company main, radio' and the 'Add Custom Label' button is missing.
Other contact entries on his phone have the same list as mine and they include the 'Add Custom Label' button.
They are both only synchronised with icloud Can anyone help please?

I have found the answer - the 'Contacts' in my mates iPhone was set to 'Exchange' set it to 'iCloud' both iPhones now have the 'Add Custom Label' option

Price Difference: Out of box w/ Missing Accessories vs Out of box w/o Missing Accessories?

Hello
Ok, so I need some help.
Last night, I purchased a Samsung 55" TV out of box. When I went home to install my brand new (used) TV. It was missing the power cord! After further examination, it was also missing the IR Extender Cable and the batteries.
On the label, it said it was "no missing accessories" but unfortunately, it was missing some key accessories to run the tv. I talked to the store and they were unable to provide me with the missing accessories and that I had to buy them individually and despite being labeled as "no missing accessories," that's the true cost of the TV.
My question, is that price correct, would there be a price difference if a out of box tv had all the accessories vs not having all the accessories?
I just want to make sure I paid the true value of the TV. As I see it, the TV may have been priced based on all the accessories but since the TV is missing accessories, the price of the TV may be different.
Your thoughts?

Hello ItsJTP,
Open box items are a great way to save on some of your favorite devices! It is sad to hear that this experience may not have met your expectations or been what we hope for our customers purchasing such items. I am sorry for any concern this may have caused you.
Open box items should be marked appropriately for any missing pieces or accessories, and then priced accordingly. With that said, unfortunately I am unable to know whether this was priced correctly, and missing accessories listed incorrectly, or if the missing accessories were listed incorrectly and thus the price was not appropriate.
With the information registered with the forum, I was unable to locate your purchase to review it. I am sending you a private message to gather further information in regards to this inquiry. You may check your private messages by signing into the forum and clicking the envelope icon in the top right corner of the page.

ADF 11g: VO attribute labels not displayed in deployed application

We are using JDev 11.1.1.2.0.
In our project we have four ViewController projects, three of which are included in the "main" view project as ADF libraries. At least one of the library projects uses attribute labels defined in view objects for the UI, for instance in a simple search field dropdown list for selecting the search attribute. When the application is run on the integrated WLS or deployed to a local WLS instance, the labels are displayed correctly as entered to the view objects:
http://img532.imageshack.us/img532/6750/adflabelscorrect.png
When we deploy the application to the remote WLS server, however, some of these labels stop working and instead the search dropdown list displays the default values (column names) for attribute labels:
http://img532.imageshack.us/img532/3811/adflabelsincorrect.png
We have checked the deployment EAR file and confirmed that the model project's message bundle does include the labels which are missing from the UI:
ses.model.vo.TukihakemuksetView.EsittelijaNumero_LABEL=Esittelij\u00E4
ses.model.vo.TukihakemuksetView.RahaNumero_LABEL=Rahanl\u00E4hde
ses.model.vo.TukihakemuksetView.HankNumero_LABEL=HankeThis problem doesn't affect all the labels though, as most of the values are correctly retrieved from the message bundle. It seems that the missing labels are at the bottom of the message bundle file, ie. the latest additions. For some reason the deployed version is not picking these up.
The remote WLS is the same version as in the dev environment (10.3.2.0).
Any ideas what might be the problem?
Thanks,
Joonas

Replying to myself here, this is most likely related to the following Metalink bug report:

REDO ALLOCATION LATCH와 REDO COPY LATCH에 대해서

제품 : ORACLE SERVER

REDO ALLOCATION LATCH와 REDO COPY LATCH에 대해서
========================================================================
redo log buffer 사용 시 wait 비율이 높은 경우 log buffer의 크기 조정 외에도
redo에 관한 latch를 조정함으로써 성능을 향상시킬 수 있다.
여기에서는 redo allocation latch와 redo copy latch의 작동 원리와, tuning
방법 등을 설명한다. 그리고 8i에서의 변경 사항도 포함하였다.
1. redo entry를 redo log buffer에 할당하는 방법
database에 변경 작업을 수행하는 server process는 PGA 부분에 변경 작업에 대한
redo entry를 만든다. 그리고 이것을 redo log buffer에 옮기는데, 이 때 먼저
할당될 redo log buffer의 부분을 allocation하고, 그 이후에 allocation 된
redo log buffer 공간에, PGA 상에 만들어 둔 redo entry를 copy한다.
Oracle은 SGA 내에서 발생하는 source code의 action의 serialization을 위해서
latch를 사용한다. 즉, log buffer에서 redo entry를 save시킬 공간을 할당하는
작업 절차도 먼저 latch를 부여받은 process가 작업하는 것이고, 할당받은
공간에 redo entry를 copy시키는 작업 절차도 latch를 획득한 다음에만 수행
가능하다.
2. redo allocation latch
모든 redo entry는 db에 수행된 작업 순서대로 redo log file에 기록되어야 한다.
그러므로 redo log buffer에 redo entry를 할당하는 작업은 항상 serialization을
유지하여야 하고, 그런 이유로 인해서 redo allocation latch는 instance마다
하나만이 가능하다.
server process는 이 redo allocation latch를 잡고, redo buffer 내에 redo
entry를 저장시킬 위치를 확보한다.
다음에 설명할 redo copy latch를 사용할 수 없는 환경에서는, redo buffer 내의
확보한 공간 내에 redo entry를 copy하는 작업도 이 redo allocation latch를
잡은 후 진행한다.
3. redo copy latch (LOG_SIMULTANEOUS_COPIES)
redo allocation latch 하나를 이용하여 redo buffer 내의 공간을 할당하고,
redo entry를 copy하는 것은, redo buffer에 대한 작업을 모두 serialize시켜
performance에 지장을 줄 수 있다.
redo entry가 위치할 공간을 확보하는 작업은 반드시 시간 순서대로 위치해야
하기 때문에 모두 순서가 유지되어야 하는 작업이지만, 일단 확보한 log
buffer의 공간에 redo entry를 copy하는 작업은 동시에 수행되어도 지장이
없다. 이것을 위해 복수 개의 redo copy latch를 지정하여, redo entry를 확보된
영역에 동시에 copy가 가능하도록 하였다. 단 이러한 copy 작업은 CPU의
작업이므로 CPU가 한장이면, 동시 작업이 불가능하여 이 redo copy latch를
사용하는 것이 의미가 없어 사용이 불가능하다.
즉, redo buffer에 대한 작업이 redo copy latch를 사용하면, 다음과 같은
절차로 수행된다.
(1) A server process가 redo allocation latch를 잡고 redo buffer 내의 공간을
할당한 후 redo allocation latch는 푼다.
(2) B server process가 redo allocation latch를 잡고 redo buffer의 새로운
공간을 할당받은 다음 redo allocation latch를 푼다.
(3) A process가 redo copy latch를 잡고 A process가 만든 PGA 내의 redo
entry를 (1)번 단계에서 확보한 공간에 copy한다.
이와 동시에 B process도 또 다른 redo copy latch를 잡고, (2)번 단계에서
확보한 공간에 redo entry를 copy한다.
redo copy latch의 갯수는 log_simultaneous_copies parameter에 의해 지정된다.
CPU가 하나이면 이 값은 0가 되어, redo allocation latch를 이용해 redo
allocation과 redo copy 작업을 한번에 수행하게 되며, default는 CPU_COUNT 값이
된다. CPU_COUNT는 operating system layer에 의해 자동으로 결정되며, init.ora
file에 명시적으로 지정하지 않는 parameter이다.
즉, multi CPU 환경에서는 자동으로 redo copy latch를 사용하게 되는 것이다.
default 외의 값을 사용하고자 한다면, $ORACLE_HOME/dbs/initSID.ora file 내에
다음과 같이 지정하면 된다. 최대값의 제한은 없다.
log_simultaneous_copies=n
redo copy latch의 장점을 정리하면, redo buffer의 공간 할당을 위해 선행된
작업이 redo entry를 copy할 때까지 기다리지 않아도 되며, redo copy 작업 자체도
병렬도 수행이 가능하다는 것이다.
4. LOG_SMALL_ENTRY_MAX_SIZE
CPU를 복수개를 사용하는 경우 redo copy latch를 사용하는 것이 redo log buffer
내의 작업에 대한 wait는 줄일 수 있음은 위에서 살펴보았다. 그런데 매우 작은
redo entry의 경우 redo entry를 copy하는 데 시간이 거의 걸리지 않은 상황에서
굳이 redo allocation과 redo copy를 별도의 latch를 이용하여 두 단계로 나누어
작업하는 것이 성능 향상에 도움이 되지 않을 수도 있다. 오히려 copy하는 데 시간이
거의 안 걸린다면 redo allocation latch 하나를 잡고서 redo allocation과 redo
copy를 모두 수행하는 것이 나을 수도 있다.
그렇다면 redo copy latch를 사용하는 상황에서 이 latch를 사용하지 않아도 되는,
작은 redo entry의 기준을 설정할 필요가 있다.
이것을 결정하는 parameter가 log_small_entry_max_size이다.
즉, log_small_entry_max_size보다 큰 redo entry는 redo copy를 위해 redo copy
latch를 사용하지만, 이보다 작은 크기의 redo entry에 대해서는 redo allocation
latch를 이용하여 redo allocation과 copy를 모두 수행하게 되는 것이다.
아무리 작은 redo entry라도 redo copy latch를 사용하게 하고 싶다면 이 값을
0으로 지정하면 된다.
5. tuning point
multi-CPU 환경에서 redo copy latch의 갯수를 늘리거나, log_small_entry_max_size
값을 줄여야 할때는 redo buffer에 contention이 발생하는 경우이다.
redo buffer에 contention이 발생하는지 확인하는 방법은 다음과 같다.
SQL>select name, gets, misses from v$latch where name = 'redo allocation';
이 값의 결과에서 gets에 대한 misses의 비율이 1%를 넘는다면 이것은 contention
이 존재한다고 판단될 수 있다. 물론 이것은 절대적인 기준은 아니어서, 1% 미만
이라 하더라도 miss 율을 더 줄이고자 할 수도 있다.
contention이 발생하면 log_simultaneous_copies의 값을 CPU의 약 두배 정도까지
증가시키는 것이 권고할 만하고, log_small_entry_max_size의 값도 0에 가까운
값으로 줄여서 contention의 상황을 지속적으로 살펴보아야 한다.
6. 8i 에서의 변경 사항
Oracle 8.1 에서는 위에서 설명한 두 parameter가 모두 나타나지 않는다.
log_small_entry_max_size parameter는 완전히 없어졌으며,
log_simultaneous_copies 값은 CPU_COUNT의 두배로 무조건 설정이 된다.
이 CPU_COUNT는 앞에서 설명한 것과 같이 operating system layer에 의해
자동으로 결정되는 parameter로 CPU의 갯수를 나타낸다.
log_simultaneous_copies가 자동으로 CPU 갯수의 2배로 지정되는 것은 모든
환경에서 대부분 최적이라고 볼 수 있으므로, user가 변경하지 않도록 하기 위해
parameter 부분에 display가 안 되도록 하였다.

Tab Budget Allocation in Marketing Plan and Campaign

Hi All,
I have problem with tab budget allocation in marketing plan and campaign (t-code: CRM_MKTPL).
Tab budget allocation is missing.
my question is where we define tab budget allocation in SPRO?
My system is CRM 5.0
Thanks and Regards,
Fariz

Hi Fariz,
On assigning one of the Plannig Profile group from the available drop down either in Marketing Plan or Campaign you should be getting additional tabs like Cost tab, Key Fig tab etc. In cost tab you can allocate the budget for Advertise, Promotion etc. As Gaurav had rightly pointed out this requires BPS integration. For any other cost planning requirement apart from the given standard key figures you would require to define them as key figures in BPS and put them in planning profiles.
Following is the path where we can define Key Figures in spro
IMG-->CRM > Marketing> Marketing Planning and Campaign management --> Key Figures Planning
Hope this might help to start with Key Figure planning

Colour Labels being reset when changing from one to another. Possibly a bug?

For some time I have suspected that I was "loosing " images that I had filtered based on their colour label. I have narrowed it down to changing the colour label of an image in just one particular way.
I think that the errors occured in in Lightroom 3 but they it always occurs in version 4
Using Develop mode
I label several images to one colour eg blue
In the filmstrip using the colour label filter select for example blue and purple which will still show all the images labelled as above
Using the colour buttons on the toolbar under the image, change the colour label of an image to purple, Since the filter is set to blue and purple the image should still be present in the filmstrip but it is missing
Searching for the image via other means eg filename I find that the colour label has been reset to none instead of changing to purple
This only happens if the colour change is done using the toolbar buttons, using any of the text menus that access the colour labels the problem doesn't occur.
The error is not limited to blue and purple labels
Am I missing something? Can anyone replicate this ?
regards
Wes

I can replicate this when using toolbars.
This doesn't seem to happen when I use the keyboard.
I can remember more older bug reports related to using the toolbar in conjuction filters. Somehow the codepath and behaviour is different the when using keyboard shortcuts. Go figure...

What determines the order of label in a label stack?

Suppose there is a PE router,take part in igp mpls,bgp ipv4 with label,vpnv4 and TE.Then when a packet pass the LSR from CE,the LSR will put several label on the packet.Then comes the question:How can the router determine the order of these labels when puting them on the packet.
I think there's two possibal answers:
first,it is define by some document,that's an arbitrary answer;
second,it is relate to the packet process flow.
I wonder what is the truth.I need some detailed explain or document.thanks!

The idea behind the stack is derived by the need to have multiple forwarding tables for the under lying forwarding planes.
1) What this means is each router as pointed by you can have multiple protocols which may be utilizing MPLS labels for data forwarding. MPLS TE will have labels of its own via RSVP to forward data on TE tunnels, VPNs will have VPN labels to forward VPN data across via MPBGP, Global routes would have labels allocated by LDP to forward data between LSR's.
2) This essentially creates multiple forwarding tables. Now where and how does the label stack come into picture, this can be answered by answering a simple question.
3) Where did the MPBGP get the label from for the VPN, from the IBGP nexthop, now is there any label to reach the next hop yes, there is via LDP, hence you get a label stack.
So whenever you build a forwarding table for any plane through a existing LSP then you have a label stack.
For eg: if you have a VPN label learnt via a LDP LSP which in turn is built via a MPLS TE LSP then you have a 3 label stack. (the lowermost being VPN since it was learnt through a next hop reachable via LDP label, which in turn was connected till the next hop via multiple TE tunnels.)
On the converse if you have a MPLS TE tunnel running between the PE's end-to-end you need not run LDP at all and the label stack to forward data across would be consiting of a VPN label and a TE label only.

How to add custom label to a new contact in address book which is synced with outlook account

Hello all,
My iPhone is synced with outlook account. When I tried to create a new contact,'Add Custom Label' option was missing. Is Apple provides any solution to handle this? Is there any documentation provided about this behavior?

The second script is working but if I need to change the link it will not allow me to edit or delete it in iCal on my desktop. The only way to edit it is to use the online iCal in me.com.
And the worst problem is that the url does not show up on my iPhone iCal. The iPhone version of iCal has limited features. So if I'm away from the office on my iPhone I still have the problem of having no link to my iCal appointment. I still end up having to use both iCal and Contacts as separate Apps.
I still dont understand why Apple wouldnt make these 2 Apps work together! It seems so obvious! thanks anyway.

Behaviour of AP Timers

Hi there,
I am currently fumbling around a little bit with the AP timers on our WLCs in order to improve convergence.
For this I activated the fast heartbeat for local mode APs.
The documentation states the normal heartbeat timer must be at least 3 times larger than the fast heartbeat timer.
Also for the AP to switch the WLC it takes to heartbeats and after those fail 7 heartbeats every second.
That would be 17 seconds with a fast heartbeat timer of 5 seconds.
I am a little bit confused regarding the relation of the heartbeat timer to the fast heartbeat timer.
As I understood the local mode APs only rely on this fast heartbeat timer and don't care of the normal one anymore.
Why should I be concerned if the normal heartbeat is not 3 times larger?
I then decided to just put it to the test and see how fast the AP converge. It took the AP about 21 seconds. I expected this variance of 4 seconds to be the preceding heartbeat, during which I denied the AP access to the primary controller.
When allowing access of the AP to the primary controller again it took about 114 seconds to switch back.
I suspect this is due to the AP Primary Discovery Timeout with a default of 120 seconds. Is this assumption correct?
I cannot explain otherwise as heartbeat messages are only sent to the current associated WLC.
I also noticed when configuring them over the CLI there is a new timer:
config advanced timers ap-primed-join-timeout
According to the CLI description:
Configures AP Primed Discovery Timeout value between 120 and 43200 seconds(12 hours).
Can someone elaborate on this command please?

Instead of posting a new discussion I will use my old thread.
The issue above is mostly solved my testing around although I still havent found out what the config advanced timers ap-primed-join-timeout does as well as the 1:3 relation between heartbeat and fast-heartbeat. If anyone knows I would be grateful for the information.
Before I come to my actual question here some background information just for the sake of completeness:
During the event of a controller outage the AP sends 5 retransmission packets by default in a 3 second interval when using the normal heartbeat.

If fast-heartbeat is configured the retransmission packet count goes down to 3 although the 3 second interval remains.

I checked the timers via show ap retransmit all
(WLC) >show ap retransmit all Global control packet retransmit interval: 3 (default) Global control packet retransmit count: 5 (default)AP Name             Retransmit Interval Retransmit count------------------ ------------------- -------------------Access-Point             3 (default)      5 (default)
It only shows the timers for the normal heartbeat procedure.
I then proceeded to change the retransmit count parameter to 8
(WLC) >show ap retransmit all Global control packet retransmit interval: 3 (default)Global control packet retransmit count: 8AP Name             Retransmit Interval Retransmit count------------------ ------------------- -------------------Access-Point             3 (default)      8
With fast heartbeat disabled it turned out that during a heartbeat timeout the retransmit count will use the new value of 8.

Now when I enabled fast-heartbeat again and did a test I noticed that the AP now also sends 8 retransmissions before it changes to the backup WLC

I then decided to switch back to the default retransmit count value of 5 but noticed that the default label is now missing in the WLC config:
(WLC) >show ap retransmit all Global control packet retransmit interval: 3 (default) Global control packet retransmit count: 5AP Name             Retransmit Interval Retransmit count------------------ ------------------- -------------------Access-Point             3 (default)      5
I did another debug with fast-heartbeat enabled which confirmed my suspicion. The retransmit count stays at 5 counts instead of only 3.

Now to my question:
Is there any way to restore the default behaviour of the timers?
I didn’t find a command to clear this configuration, already tried to reboot the WLC, but nothing helped.
Any help appreciated.

Member formula error while retrieving in smartview?

I am trying to execute this member formula
IF (@ISMBR(@RELATIVE("SENDER_PROJECT",0)))
IF ("Allocation Pct" <> #Missing)
"Allocation Amount"=("Account_sub1"->"PFL_Projects"->@MEMBER(@SUBSTRING(@NAME(@CURRMBR("Project")),6))*"Allocation Pct");
ELSE
"Allocation Amount"=("Account_sub2"->"PFL_Projects"->@MEMBER(@SUBSTRING(@NAME(@CURRMBR("Project")),6))*(@PRIORS( SKIPMISSING, "Allocation Pct")));

ENDIF;
When I try to retrieve the data for this formula, I get the following error.
Error(1200370)Error executing formula for [R_Segment Allocation Amount] (line 1): attempt to cross a null member in function [@X]
Is there anything I can modify to not have a null member.
Thanks!!

Thanks! You were right I created the a sub hierarchy with the specific members and substring command was set a little wrong, I had one higher value.
I reset it to as shown below and it worked!
@MEMBER(@SUBSTRING(@NAME(@CURRMBR("RETL_H_PROJET")),5))
