Cache Insert for an already existing key is firing two update events

Using an INamedCache I perform an insert to update the values of my item that is already in the cache. I have listeners on the cache, in particular I have a DelegatingCacheListener that listens on EntryUpdated.
On doing this insert once (and only once, I think!) my update event handler gets invoked twice. I have put breakpoints in all conceivable places that might raise this event, do an insert or update this key but it only ever hits my insertion point once.
I have looked at the args of the event and seen that on the first invocation my old value is A and new value is B. For the second invocation my old value is B and New value is C. The second invocation new value object is only different by a single member which is a time value that I set and this difference is only a second. This kind of implies that somehow my own application/code is inserting twice into the cache for the same key/value.
Has anyone seen this symptom before?
Is there somehow that I can see what is inserting into the cache?
Let me know if I can provide more information to help.

Changed the title grammar

Hi Kunal -
First, just to narrow this down, it appears that your code is running in .NET. Is there other logic deployed as part of this application, e.g. application logic on the server side (the "back end") that might be doing something? This would include anything from the incubator (e.g. push replication).
Second, what does your listener do when it receives the event?
Third, are there other listeners for the event that may be doing something when the first change appears?
The event originates from within the cluster, from the server that "owns" the specific piece of data that your are inserting, so unless the value is changing there twice, you should not get two events. I would start by tracking down all of the places that change the time value, since you can see that is the value that is being changed.

Mess SR 053 - Creation not possible (Mapping for product already exist..

There is an error ocurring when the CIF is executed, this message I can see in the transaction SMQ1, the error " SR 053 - Creation not possible (Mapping for <product> already exists <product> ", the product really exists in APO but I don't know why this error occur because in this case the material should be updated. Anyone know why this error occur ?? and how can I fix ??
When I try to execute only this material in CFM2 no errors occur.
Regards,
Edson Suzuki

We did faced a similar problem. The reason was the external material number was different in both cases.
ie the already existing record has the external material number padded with '0000' and the one coming doesn't have leading '0000'
If this suggestion helps you, please reward by points..

Generate a Number for a already existing table with records

Hi All,
Is it possible to generate number for a column in a table. The table already has 50,000 records. I have a empty column in which I want to generate number sequentially for reference purpose......
Whether it can be done ?????
I was thinking og Merge/ rownum I didnt get any possibls solution out of it .........any suggestions....
Thanks
Ananda

I have a empty column in which I want to generate number sequentially for reference purposeThe following table content :
Oracle
DB2
MSSQLNow, you have to put a kind of ID, but what row will get the 1st ? What row will get the 2nd ? etc.
If you don't care, then sequence as suggested is your friend. Then, you could use also sequence for further insert.
Nicolas.

Global-Cache-Manager for Multi-Environment Applications

Hi,
Within our server implementation we provide a "multi-project" environment. Each project is fully isolated from the rest of the server e.g. in terms of file-system usage, backup and other ressources. As one might expect the way to go is using a single VM with multiple BDB environments.
Obviously each JE-Environment uses its own cache. Within a our environment with dynamic numbers of active projects this causes a problem because the optimal cache configuration within a given memory frame depends on the JE-Environments in use BUT there is no way to define a global JE cache for ALL JE-Environments.
Our "plan of attack" is to implement a Global-Cache-Manager to dynamicly configure the cache sizes of all active BDB environments depending on the given global cache size.
Like Federico proposed the starting point for determining the optimal cache setting at load time will be a modification to the DbCacheSize utility so that the return value can be picked up easily, rather than printed to stdout. After that the EnvironmentMutableConfig.setCacheSize will be used to set the cache size. If there is enough Cache-RAM available we could even set a larger cache but I do not know if that really makes sense.
If Cache-Memory is getting tight loading another BDB environment means decreasing cache sizes for the already loaded environments. This is also done via EnvironmentMutableConfig.setCacheSize. Are there any timing conditions one should obey before assuming the memory is really available? To determine if there are any BDB environments that do not use their cache one could query each cache utilization using EnvironmentStats.getCacheDataBytes() and getCacheTotalBytes().
Are there any comments to this plan? Is there perhaps a better solution or even an implementation?
Do you think a global cache manager is something worth back-donating?

* Estimating JE in-memory sizes as a function of key and data size is not
* straightforward for two reasons. There is some fixed overhead for each btree
* internal node, so tree fanout and degree of node sparseness impacts memory
* consumption. In addition, JE compresses some of the internal nodes where
* possible, but compression depends on on-disk layouts.
* DbCacheSize is an aid for estimating cache sizes. To get an estimate of the
* in-memory footprint for a given database, specify the number of records and
* record characteristics and DbCacheSize will return a minimum and maximum
* estimate of the cache size required for holding the database in memory.
* If the user specifies the record's data size, the utility will return both
* values for holding just the internal nodes of the btree, and for holding the
* entire database in cache.
* Note that "cache size" is a percentage more than "btree size", to cover
* general environment resources like log buffers. Each invocation of the
* utility returns an estimate for a single database in an environment. For an
* environment with multiple databases, run the utility for each database, add
* up the btree sizes, and then add 10 percent.
* Note that the utility does not yet cover duplicate records and the API is
* subject to change release to release.
* The only required parameters are the number of records and key size.
* Data size, non-tree cache overhead, btree fanout, and other parameters
* can also be provided. For example:
* $ java DbCacheSize -records 554719 -key 16 -data 100
* Inputs: records=554719 keySize=16 dataSize=100 nodeMax=128 density=80%
* overhead=10%
* Cache Size Btree Size Description
* 30,547,440 27,492,696 Minimum, internal nodes only
* 41,460,720 37,314,648 Maximum, internal nodes only
* 114,371,644 102,934,480 Minimum, internal nodes and leaf nodes
* 125,284,924 112,756,432 Maximum, internal nodes and leaf nodes
* Btree levels: 3
* This says that the minimum cache size to hold only the internal nodes of the
* btree in cache is approximately 30MB. The maximum size to hold the entire
* database in cache, both internal nodes and datarecords, is 125Mb.

Update Time where Date already exists

Hi,
When i am trying to update time in the column where date already exists, i tried using the update query, but time is not getting updated.
UPDATE ABC SET ATTRIBUTE=TO_DATE('09/30/2011 12:00:00 AM','MM/DD/YYYY HH:MI:SS')
Attribute = 9/30/2011 (As per current record in DB) and i want to add time also..
So when i try updating the record, i dont get any errors, but the time does not get updated, can any one help me for this issue.???
Datatype of Attribute is Varchar2(150)
Thanks

Is there anyway to update a record throgh TO_CHAR function???

Folio Upgrade: Error #3115table 'folioFolderCache' already exists

I just upgraded the Folio Builder with a recent version for Indesign CS5.
It worked ok on initial install for a few hours until I closed Indesign. And when I re-opened Indesign I started getting this error message:
An error has occured while saving your changes to local cache [Error #3115table 'folioFolderCache' already exists]
I cannot use Folio Builder. Does anyone know how to get it working again?
:-S
Thanks in advance.

Item or object?
For "Object already exists" or "Access denied" errors when installing try opening Control Panel > Programs and Features > View installed updates then checking for Security Update for Microsoft Windows (KB2918614). Uninstall if you have it, then reboot and try installing again.

Function module in Infotyp which checks if identical data already exists

I want to create a new hr master data (tcode pa30) for Hans Müller in e.g Company X and fill out the necessary fields in Infotype 0001,0002 (Name, Birthdate, etc. ) u2013 done !
After creating the new hr master data for Hans Müller Iu2019d like to fill out a special Infotyp (0032) namely Internal Data.
PROBLEM:
While filling out the IT 0032 I do not know if the person - Iu2019ve created a new master data for - is already existing in the system ( but in other e.g Company Z) .
So what I need is a function modul in the Infotype 0032 which checks if there is already a person with the same data existing in any company (the whole data bank) using 3 characters from Infotype 0002 (Personal Data) namely , First name, Last name, Birthd. .
And if a person with the same first name ,last name and birthday is already existing the function module should link to that one or just show me a information.
Also tried to show you my problem on a graphic,
Function_Module_Infotyp0032.png
I hope you can help me. I would be very thankful for any hints , information or programming approach.
Regards
Sean

the problem with your solution approach is that there could be different pers. no. for the same person in my issue.
If I understood you well, that won't be a problem, since you already know which PERNR to use (The one you are using to update IT0032) In that case you only have to check if for that PERNR more than one record in PA0001 with different Company Code is present.
If your problem is that another person with the same name and same date of birth is active in the system with different Company Codes it would be similar.
For instance: Let's say that you find 2 different PERNRs for a given Name and Date of Birth in PA0002, then you can check IT0001 and look for the BUKRS value for those 2 Personel Numbers. If the values found are different you can raise the error message or whatever you need.

I'm getting an 'objects already exist' error when trying to download itunes

My iPhone 6 wouldn't connect to iTunes since it need to update. So I went to uninstall iTunes and all it's contents. I went to download iTunes again, but when I did I received an 'Object already exists' error. I went to look at more information on the Apple website and I tried everything I could but I keep receiving the error. I uninstalled anything related to Apple on my computer and I went to the Program Files folder on my computer and found nothing related to Apple so I'm pretty sure I deleted all the data already. I really need help with this. I have a Windows 7 computer.

For "Object already exists" or "Access denied" errors when installing try opening Control Panel > Programs and Features > View installed updates then checking for Security Update for Microsoft Windows (KB2918614). Uninstall if you have it, then reboot and try installing again.

Primary key constraint firing when there's no need

Hi All,
I've got a very weird problem.
I've written a PL/SQL procedure to insert addresses into a tabel. The adresses are assigned an unique number by means of a sequence. This unique number is the primary key of the table and has to be unique.
The following thing occurs: The primary key constraint fires whenever i try to insert a record and i can't figure out why.
I use the following code
PROCEDURE mk_adr(klant NUMBER, receiver NUMBER) IS
oidtje NUMBER DEFAULT 0;
BEGIN
BEGIN
SELECT lea_adr_seq.NEXTVAL INTO oidtje
FROM dual
INSERT INTO lea_adr (
oid, object, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
relation_id, offerrec_id,
h_trans_van,
h_geldig_van,
h_gebruiker
SELECT oidtje, oidtje, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
null, receiver,
To_Date('01-01-2000'),
To_Date('01-01-2000'),
'conv'
FROM lea_adr
WHERE relation_id = klant
EXCEPTION
WHEN Others THEN
conv_algemeen.debugMessage('mk_adr :: '||SQLERRM);
END;
END;
as you can see the very first thing i'm doing is selecting a new unique number into oidtje from the sequence which provides the numbers. Then i use it to insert the record. The insert fails with the primary key constraint firing saying that oid is not filled with an unique number.
When i do "select max(oid) from lea_adr;" I get a number lower than the number the i get when doing "select lea_adr_seq.nextval from dual;"
So am i overseeing something or is something very obvious going wrong ?
Patrick

Write your procedure like the following and it will work.
PROCEDURE mk_adr(klant NUMBER, receiver NUMBER) IS
BEGIN
INSERT INTO lea_adr (
oid, object, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
relation_id, offerrec_id,
h_trans_van,
h_geldig_van,
h_gebruiker
SELECT lea_adr_seq.NEXTVAL, lea_adr_seq.NEXTVAL, streetname,
housenumber, housealpha, ponumber,
postcode, cityname, locationdesc,
province, kind, country_id,
null, receiver,
To_Date('01-01-2000'),
To_Date('01-01-2000'),
'conv'
FROM lea_adr
WHERE relation_id = klant
EXCEPTION
WHEN Others THEN
conv_algemeen.debugMessage('mk_adr :: '||SQLERRM);
END;
Using the lea_adr_seq.NEXTVAL more then once in the SAME select will return the same value for both calls.
SQL> create sequence test
2 ;
Sequence created.
SQL> select test.nextval,test.nextval from dual;

What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

My final data table contains a two key columns unique key constraint. I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
(not unique) in the daily capture table). I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). Currently, what I do is to select * into a #temp table from the join
of daily capture and final data tables on these two key columns. Then I delete the rows in the daily capture table which match the #temp table. Then I insert the remaining rows from daily capture into the final data table.
Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table? How would this look?
What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key. You need to fix this error. What ETL tool do you use?
>> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
MERGE statement; Google it. And do not use temp tables.

How to insert data from a table into itself if they don't already exist meeting a certain condition

First, let me apologize as I did not write/design this mess, just inherited this terrible design and legacy application!
I have table of companies and a table of suppliers with various attributes and of them being a bit column of is_public. The public suppliers then need to be inserted into the table as suppliers for the other suppliers.
As an example, in the company table company 'PUB01' is flagged as a public supplier (Company.IS_PUBLIC_SUPPLIER = 1). Therefore in the Suppliers table I need to insert a row for each each of PUB01's suppliers in that same table to all the other suppliers
in that table if they do not already exist as follows:
Here is a sample of the table structure:
CREATE TABLE [dbo].[COMPANY](
[COMPANY_ID] [nvarchar](15) NOT NULL,
[COMPANY_NAME] [nvarchar](100) NOT NULL,
[IS_PUBLIC_SUPPLIER] bit NOT NULL,
CONSTRAINT [PK_COMPANIES] PRIMARY KEY CLUSTERED
[COMPANY_ID] ASC
) ON [PRIMARY]
GO
CREATE TABLE [dbo].[SUPPLIERS](
[SUPPLIER_ID] [int] IDENTITY(1,1) NOT NULL,
[COMPANY_ID] [nvarchar](15) NOT NULL,
[SUPPLIER_NAME] [nvarchar](100) NOT NULL,
[PUBLIC_SUPPLIER_ID] [int] NULL,
CONSTRAINT [PK_SUPPLIER_MASTER] PRIMARY KEY CLUSTERED
[SUPPLIER_ID] ASC
GO
Thanks!

Thanks Visakh! Will that work if some have already been inserted previously?
Yes
but if you want to exclude them use this
INSERT INTO Suppliers(Company_ID,Supplier_Name,PUblic_Supplier_ID)
SELECT s1.Company_ID,
s2.Supplier_Name,
s2.Supplier_ID
FROM Suppliers s1
CROSS JOIN Suppliers s2
WHERE EXISTS(
SELECT 1
FROM Company
WHERE Company_ID = s2.Company_ID
AND IS_PUBLIC_SUPPLIER = 1
AND s1.COMPANY_ID <> s2.COMPANY_ID
AND NOT EXISTS (SELECT 1
FROM Suppliers
WHERE Company_ID = s1.Company_ID
AND Supplier_Name = s2.Supplier_Name

Hi Kamalakar
I think this problem happens due to wrong content of SDMKIT.JAR - incorrect crypto SDA is deployed.I dont know the installation procedure you followed because normally this error wont come.
I would rather suggest a work around seeing your problem
Edit the keydb.xml exchanging [ERROR] with [OK]
Follow the above step and restart your installation.

Inserting a new row in a child table referencing an already existing parent

I have two tables PARENT & CHILD (one to many), both of which are populated at different times.
In our toplink mappings, parent contains a collection of child Domain Objects, & and child Domain object contains a one - one to parent.
How can I insert a new row in a child table with reference to an already existing row in parent?
When I fetch the parent Domain object and try to set it in the child Domain Object and use the unitOfWork.registerObject() it goes into a circular loop of selecting from 2 other tables.
Please suggest.

Odd, have you disabled caching and indirection? (NoIdentityMap, dontUseIndirection, or alwaysRefresh/disableCacheHits). If so, then this could be the issue.
Otherwise please include the sample code you use to perform this, and verify that you do not have any unusual code in your set/get methods or in descriptor events. Also turn TopLink logging on and include a sample. Also ensure that you do not modify your objects until after registering them in the unit of work, and only modify the unit of work clones.
