Head of Line Blocking (HoL Blocking)

The one in the nearest server room is a HP 2810-24G (J9021A), looking up specs I see mention of First In First Out (FIFO) which is a type of input buffering correct? I would have to check the other buildings to check their switches but i would assume they are along the same type of switch.

Hello folks, I have been searching and searching for information on Head of Line Blocking and only coming up definitions, plenty of diagrams and even a few examples of how it can be fixed (VOQ and DBBM). So I'm asking this community for some advice on how I can tell if HoL Blocking is causing some of our more annoying tickets about connection issues to re-emerge.
Whats the best way to identify if HoL Blocking has become an issue?
All the switches are HP and some are 24 port and others 48 port.

Line of White blocks in screen (iPhone 5)

Since a few weeks my iPhone 5 is showing a line of White 'blocks' on the top edge of the screen (over status bar). The effect sometimes disappears after the phone has been in standby, only to re-appear after using an App.
I have tried:
- complete switch off/re-boot
- complete erase of the phone to factory settings
In the latter case, the effect returned after synchronizing with iTunes.
Any ideas on how to get rid of this? It seems logical to assume that a specific App might be the cause, but I have no idea which one. I suspected Emoji, but erasing it didn't solve the problem. iTunes does not show the app anymore, so I am assuming that it has been erased properly.

I had the same problem, especially when I was opening the calculator from the control centre. I had a lot of apps grouped based on category. I fixed the problem resetting the main screen, all the apps were ungrouped and since then I’m not having that white block on the screen.
Please let me know If it worked for you!

RAC에서 Current Block과 CR Block

RAC 환경에서 시퀀스를 캐싱을 많이 할 경우 Index Leaf Block Contention 감소시켜서 속도를 증가 시킬수 있다고 들었습니다.
Row가 Insert 될 때마다 가장 큰 Key를 가진 Index Leaf Block이 값이 계속 증가하면서 바뀌므로, 이것은 RAC 환경에서 노드간 Current Block과 CR Block의 높은 전송량을 유발하며 성능 저하 현상을 일으킨다고 하는데요.
"노드간 Current Block과 CR Block의 높은 전송량을 유발" 한다는 말이 잘 이해가 안가는데 설명 부탁드립니다.

두가지에 대한 정의
cr block : Consistent Read block
하나가 업데이트 중인데 커밋이 되지 않았을 경우 읽기 일관성을 위해
누군가 select하게 되면 과거의 이미지를 만들어야 하는데 이는 언두세그먼트에가서 과거의 이미지를 찾아서 만들어야 한다. 이는 하나의 버퍼로 사용되지 않고 이 때 생성되는 버퍼블록이 cr block입니다. ( 과거와 현재의 ..버퍼 ) insert, delete는 cr block에 포함되지 않습니다. update만 해당됩니다.
current block
DML을 통해서 수정을 위해서 데이터를 읽을 때에 segment의 block을 읽을 때에 이것을 current block이라 한다. select의 경우에는 full scan 할 경우에 segment header를 읽는 것이 current block이 된다.
누군가 테스트를 한 것인데 너무 좋은 자료라 올립니다.

X$BH
Last time, I viewed STATE column of X$BH in a single server and in a single session and examined the following points:
CR block is not created by SELECT or INSERT queries.
CR block is created by UPDATE queries.
There are some cases where CR block is not created by UPDATE queries, though. I will analyze these cases in this issue. DELETE queries operate almost the same as UPDATE queries.
The following is the testing environment:
(Environment)
Linux 2.4.2-2
Oracle9i EE Release 9.2.0.1.0
(Table configuration)
SQL> desc test
Name Type
ID1 NUMBER
ID2 NUMBER
TEXT VARCHAR2(2000)
*Grant INDEX (TEST_IDX) to ID1
Table contains following data.
ID1 ID2 TEXT
1 1 insight
2 2 insight
3 3 insight
I executed the following statement last time.
SQL> update test set id1 = 1 where id2 =2;
WHERE clause specifies the row ID2. As ID2 is not indexed, full scan will be performed to update.
The following query specifies ID1 in WHERE clause. As ID1 is indexed, index scan will be performed to update.
(UPDATE query)
SQL> update test set id1 = 1 where id1 =2;
*ID1 is specified in WHERE clause so that index scan
is performed.
(Status of database buffer)
SQL> select
o.object_name
,decode(state,0,'free',1,'xcur',2,'scur',3,'cr', 4,'read',5,'mrec'
,6,'irec',7,'write',8,'pi') STATE
, count(*) BLOCK
from x$bh b , dba_objects o
where b.obj = o.data_object_id
and o.object_name like 'TEST%'
group by o.object_name, state
OBJECT_NAME STATE BLOCKS
TEST xcur 2
TEST_IDX xcur 1
CR block is not created, as you see. Regarding index, there is only one block on database buffer. When I previously performed full scan under the condition where there was no data to be updated, CR block was not created.
Status of database buffer when there is no target data
to be updated at full scan.
SQL> update test set id1=3 where id2=5;
*ID2 is not indexed. There is no such data as ID2=5.
0 row updated
OBJECT_NAME STATE DBARFIL DBABLK BA
TEST xcur 1 70913 54D28000
TEST xcur 1 70914 54D20000
CR blocks are created in the following cases.
CR block is created (in a single session)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
UPDATE SELECT INSERT
Full scan Yes No --
Index scan No No --
In a single session environment, CR blocks are created only by UPDATE query at full scan. Why CR blocks are created under this condition?
CR block itself is a read consistent block, but I wonder why CR block is created in a single session environment. I assume that CR block is created to create rollback information or to satisfy lock function.
CR block is not created at index scan because it is possible to identify ROWID of target data from the index. As UPDATE process is performed by each row, CR block is not necessary.
Lastly, I will examine a mechanism of current block updating, which is quite different from the one of full scan and of index scan.
The following table indicates the changes in the buffer address of a current block at index scan.
UPDATE at index scan:
[Before UPDATE]
OBJECT_NAME STATE DBABLK BA
TEST xcur 18716 54D0E000 <-target block
TEST_IDX xcur 18724 54D04000
[After UPDATE]
OBJECT_NAME STATE DBABLK BA
TEST xcur 18716 54D0E000 <-target block
TEST_IDX xcur 18724 54D04000 *No changes
I don't see any changes in the buffer address. This means that the data in the current block is updated directly.
The following table indicates the changes in the buffer address of an XCUR block at full scan.
UPDATE at full scan:
[Before UPDATE]
OBJECT_NAME STATE DBABLK BA
TEST xcur 18717 54C3A000 <-target block
[After UPDATE]
OBJECT_NAME STATE DBABLK BA
TEST xcur 18717 551F2000 <-target block
TEST cr 18717 54C3A000 *BA is changed
|
BA of current block before being updated
I see changes in the buffer address. In addition, the current block is changed to CR block after updating. The process is performed as follows:
1. A current block (XCUR) in 54C3A000 is copied to 551F2000.
2. The current block is changed to CR block.
3. Update process is performed to XCUR.

Displaying header and line items

Hi,
i) i have a fieldname i.e text and its value to display in the bodypage (body)..
i want to display the text and its value only if the value is there.. otherwise it should not be displayed and a blank line also should not appear
in smartforms we can handle that in conditions in the corresponding node, how we do the same in adobe forms?
ii) suppose i have header and line items and for each header item i want to display the line items, both r in 2 tables how can we handle this
Thanks

Hi Shekar,
The following solutions useful if you are using printbased forms.
1. To display the field if the value is there.
->In the Context you can define the condtion on the filed.
->You can write a script on the subform superior to the field
[code]      if ( $.field.rawValue == <value> ) then
            $.field.presence = hidden
      endif [/code]
2. Header and item table
In the SFP context drag the header table from interface.drag the item table from interface on the DATA in the header table. it will placed at the end of the header table. Now select the item table select where clause in the properties ( at the bottom of the screen ).there you create a line for condition using create button. drag the field from header table field ( say header-matnr ) on the right side and then drag the same field from the item table ( say item-matnr) in the left side.This will filter the item records relevent for header record.

Error in reading (block 3, # blocks 8) of control file

Hi All,
My database experiencing this error :
ORA-00204: error in reading (block 3, # blocks 8) of control file
ORA-00202: control file: 'C:\ORACLEXE\ORADATA\XE\CONTROL.DBF'
ORA-27091: unable to queue I/O
ORA-27070: async read/write failed
OSD-04006: ReadFile() failure, unable to read from file
O/S-Error: (OS 23) Data error (cyclic redundancy check).
Worst part we do not have latest backup and makes things weird.
My Control file seem corrupted.

Error: ORA 204
Text: error in reading control file <name> block <num>, # blocks <num>
Cause: A disk read-failure occurred while attempting to read the specified
control file.
The block location of the failure is given.
Action: Check that the disk is online.
If it is not, bring it online and shut down and restart Oracle.
If the disk is online, then look for operating system reasons for
Oracle's inability to read the disk or control file.
Use the mutiplxed controlfile if you have already available to start your instance...

Help in Reports 6i - Header and Line

Hi Gurus,
I have a requirement that I need to pull the Header and Line information in the custom oracle apps report.
If header record is not there for the filter criteria then I should display 0 in the header and print the corresponding lines for the header.
If header record is present and there is no line record for it then I need to pull the header record alone and no lines for it.
If both header record and line records are there then I need to pull the header record and corresponding lines for it.
I am pulling the header record from the table prior to the parameter <period_from>
I am pulling the lines record from the table based on the parameter between <period_from> and <period_to>
Pls note that header record will have always only one record for the lines and the line record may not have or may have 1 or more line for each header.
Kindly could you advise me as to how to make this happen.
Thanks,
Geno

Remarks: In my case, the images are stored in a physical drive.
Hope this help.

Error : Transaction header and line tables cannot be empty

please can some one help me.
when i want to create an invoice without anuy line, i have the error : Transaction header and line tables cannot be empty .
can some one tell me how can i solve this
regards.

Hi,
I really don't know if it is possible to create an invoice in AR with no transaction lines. When I interface invoices from another system to AR (and there is no need to detail inventory items), I use a single line with a dummy inventory item or with no inventory item (inventory_item_id and warehouse_id set to null) in transaction lines, and I use the description field to describe the link to the other software in a user-friendly way.

Dimension with header and lines information

Hi Experts
I am using Oracle 11g for database , Oracle Admin Tool for repository creation
Source : EBS R12
Target : OBIEE
In EBS R12 , I have gathered information about inspection [Inspection is our customized form in EBS , In Inspection we contain information about Jobs , WorkOrder , Asset etc]
Some Inspection form have header information only and Some Inspection form have header and line information as well [there is no measures]
I have confused about Header and Lines data in dimension tables ! how can I handle with it?
In All inspection form some fields are common in header information
Ryte now I have broke into two tables
1: Dimension [Header and Lines]
2: Factless Fact Table [Contains only FK]
I want how can I merge two dimensions for get common information about different inspections?
and how can I handle the Lines data in dimension table?
Please proposed the best technique
Best Regards,
ZafaR

Hi SqlCraze,
According to your description, you want to load a “Header” table data with FileIdentifier, Code and ID columns and a “Detail” table data with Year, Type, LegalID and Amount columns from the xml file.
Based on my research, the reason why you can only see 3 columns "FileIdentifier, Code, ID" in the XML Source is that there are only one element named includedFileHeader which contains those three columns.
So if we want to achieve your requirement, we should add another element which contains four columns "Year, Type, LegalID, Amount" in the XML file. For more information, please refer to the following steps:
Modify the XML file as below:
<?xml version="1.0" ?>
<Report xmlns="http://......... ">
<includedFileHeader>
  <FileIdentifier>677ff108</FileIdentifier>
  <Code>XYZ</Code>
  <ID>17437</ID>
</includedFileHeader>
        <IncludedFileDetail>
<Year>2014</Year>
<Type>P</Type>
<LegalID>Test - 17437</LegalID>
<Amount>969.33</Amount>
        </includedFileDetail>
</Report>
Use the modified XML in the XML Source, we can see two Output name: includedFileHeader and IncludedFileDetail.
Connect to a SQL Server Destination with “IncludedFileHeader” as Output, another with “IncludedFileDetail” as Output.
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.

Blocking Session - blocked SQL - SELECT SYSDATE FROM SYS.DUAL

Oracle 10.0.0.4g
When database execute some big and long queries/operations my system is slow and some users wait, can’t work (they work with some Oracle forms applications ) because I often have blocking session.
I found up that this blocking sessions block only this query of another user:
SELECT SYSDATE FROM SYS.DUAL
Or:
+10-АВГ-2009 08:51:10 User X1 ( SID= 222 ) with the statement: SELECT ... is blocking the SQL statement on Y1 ( SID=333 ) blocked SQL -> SELECT SYSDATE FROM SYS.DUAL+
When I kill one of the blocking session another session take his place and do the same:
+10-АВГ-2009 08:53:10 User X2 ( SID= 444 ) with the statement: SELECT ... is blocking the SQL statement on Y2 ( SID=555 ) blocked SQL -> SELECT SYSDATE FROM SYS.DUAL+
When long queries finished everything is OK.
Please Help Me!!!
