What is meant by a resource leak ?

What is meant by a resource leak ?

Garbage collection manages only memory, not other system resources. If your Java program has plenty of free memory, garbage collection will not be triggered automatically. Usually, however, there are other resources that are more limited than memory. For example, all OSes have limits on the number of sockets, file handles, etc. that can be open. Sometimes this limit is quite low. This is true even on a desktop, e.g. if your system has 128KB of memory, your Java program can easily allocate all the available file handles without coming near to filling up the heap. If this happens, your Java program will fail. This is what we call a resource leak; the unintentional maintenence of references to non-memory resources.
This is why it is important in Java to explicitly manage non-memory resources. Classes which utilize non-memory resources should provide ways to explicitly allocate/deallocate those resources, independent of garbage collection. For example Socket, InputStream and OutputStream each provide explicit close() methods for deallocation of file descriptors, Window provides a dispose() method to free the window handle, etc. The way to properly use these classes is to allocate using the constructor, then deallocate using the appropriate method (deallocation is preferably done in a finally{} block, so it will execute whether or not an exception is thrown during use). These classes do release these non-memory resources in their finalize() method, but remember that the finalizer only gets called by the garbage collector, and if the object is never collected, it will never be finalized, hence will never release the resources.

Large number VSS errors "The specified network resource or device is no longer available."

I have a 2 node Hyper V Cluster backed up via Veeam Off-Host Proxy. I've already logged, without answer, a thread about the Off-Host Proxy server randomly (I guess) creating new duplicate iSCSI connections.
Today I have a single VM that won't backup. On inspection through the hosting servers Application Log I see a high amount of VSS errors being logged which I believe is possibly related to the iSCSI issue being logged by the SAN.
I'm not sure how to "show" the issue without a giant wall of the events but there is like half a dozen different events being logged when whatever this is is happening. For instance as well last night 60/61 VMs backed up find, but these errors
were logged constantly while the backup ran...
The question as well is is this a Windows/VSS issue, a Veeam issue or a Equallogic issue?
Also how do I find what '\\?\Volume{06fba49e-9519-11e4-80cc-000af75dc050}\'. actually is?
In order of how they come I guess:

This is the issue having with redundant iSCSI connections being created:
Not sure this is a Veeam issue, just that it's occurring with Veeam backup process.
We have a server configured as an Off-Host Proxy with Veeam; it connects to the SAN storage via iSCSI same as the other hosts but accesses the storage as read only.
Randomly we will get alerts from the SAN as below:
iSCSI login to target '172.16.0.50:3260, iqn.2001-05.com.equallogic:8-661fc6-e612eedc6-32600005c9254a75-arcvmstore1-2015-01-03-14:13:37.2774.1' from initiator '172.16.0.44:64108, iqn.1991-05.com.microsoft:arcbackproxy.domain.local' failed for the following reason:
Requested target not found.
On inspection of the Off-Host Proxy's iSCSI configuration additional iSCSI connections are present as inactive, with an existing connections name amended with the date at the end. For instance (and in the example error above) there will be:
iqn.2001-05.com.equallogic:8-661fc6-e612eedc6-32600005c9254a75-arcvmstore1
and
iqn.2001-05.com.equallogic:8-661fc6-e612eedc6-32600005c9254a75-arcvmstore1-2015-01-03-14:13:37.2774.1
Not really causing an issue, the backups are running OK, or any issues we have aren't related. But getting annoying getting the alerts from the SAN of the Off-Host Proxy trying to connect to an incorrect iSCSI target.
Any ideas why this is occurring?
Obvious is we delete the extra connection, which stops the alert, but the issue will reoccur within a day or two usually.
Today I found twice the alert as above and sure enough the iSCSI on the Off-Host Proxy is as below:
Maybe these redunandant connections being created is related? Maybe that's the where the "The specified network resource or device is no longer available." is coming from or something?

What is meant by cost element

hi
what is meant by cost element

HI.
Differentiation of Cost Elements
Use
In call management, it is necessary to differentiate cost elements further for the settlement of orders in profitability analysis. Both the costs incurred and the sales deductions are classified according to their source, and assigned to the appropriate cost elements. For example, the following costs are differentiated:
Sales costs
Warranty costs
Good will costs
Sales deductions due to warranty
Sales deductions due to good will
The differentiation of costs and sales deductions enables you to assess more accurately the profitability of your products.
Integration
The differentiation of cost elements is only of use if the service orders are settled in profitability analysis.
Prerequisites
Resource-related billing must be performed for service orders.
You must have defined the accounting indicator in Customizing for Plant Maintenance.
When you create a service order, you define the accounting indicator in the header, under administrative data. Currently it is only possible to have one accounting indicator per order.
Once the order is released, the accounting indicator can no longer be changed in the order header.
Features
When actual postings are made for a service order, the system creates CO single records and a CO totals record. When doing this, it copies the accounting indicator defined in the order header, and enters it in the origin of the totals or single records.
In addition to the variance class and the cost element, the accounting indicator is a further characteristic of the PA transfer structure.
The transfer of the accounting indicator to the origin also makes it possible during the settlement of a service order in profitability analysis, to navigate more specifically in the PA transfer structure. The costs and sales deductions for warranty, good will, and sales are entered in the respective value fields.
Reward all helpfull answers.
Regards.

What is meant by CREATE PIM ATTRIBUTE FOR ITEM

Hi,
I'm working on a code for item interface in R12, could you let me know on below:
1) What is meant by Creating PIM Attribute for Item
2) what is the use of ego_user_attr_row_obj
Thanks.

"Create" means that the Time Capsule will broadcast a wireless signal. Other devices like computers, iPad, iPhones will be able to connect to this wireless network.
"Extend" is used by a remote device to provide additional wireless coverage.
If you have a Time Capsule "creating a network", then you could use another Apple device like an AirPort Extreme or AirPort Express in a remote location to "extend" the network and provide more wireless coverage in that area.

What is meant by functun module

Hi Gurus,
Can you please explain me what is meant by function modue and importance of this?
Thanks in advance
venkat

Hi Venkat,
Your question is not clear as to whether you want to about function module in ABAP or a Functional module. Anyway..........pls find answer for both below -
ABAP function module -
Function modules are procedures that are defined in special ABAP programs only, so-called function groups, but can be called from all ABAP programs. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the SAP System. They are managed in a central function library. The SAP System contains several predefined functions modules that can be called from any ABAP program. Function modules also play an important role during updating and in interaction between different SAP systems, or between SAP systems and remote systems through remote communications.
SAP Functional Module -
SAP functional module represents each functional area of an organisation. Each module helps in mapping respective business processes into SAP. The following is the broad bifurcation of Functional Modules -
ACCOUNTING - FINANCIAL ACCOUNTING Module
LOGISTICS - SALES AND DISTRIBUTION Module, MATERIALS MANAGEMENT Module, QUALITY MANAGEMENT Module, PRODUCTION PLANNING AND CONTROL Module
PLANT MAINTENANCE Module
PROJECT SYSTEM Module
HUMAN RESOURCES - HUMAN RESOURCE Module

What is meant by 3tier

difference between sap& erp.
what is meant by 3tier architecture?what are advantages & disadvantages of 3tier.architecture.

Hi,
SAP means System Application n Products in Data Processing.First it was an MRP package ie; Material Resource Planning. Later they thought that SAP has mnay modules like SD,MM,PP,HR FI/CO etc..... So first its the work of the HR to get the project..Later we MM people they take care of the material .....n then finance like that it has formed an organization....From then it has changed from MRP package to ERP package.We have 31 ERP packages out of them we have people soft, seibles, Oracle Finanace,L . D Edward, BAAN,RAM Co, SAP-68% etc....
In three Tire Architecture :
It is mutually independent as well as mutually independent.
It consists of Presentation layer, Application layer and Data base Layer.
Presentation Layer is a Graphical user-interface.
Application Layer deals with sales n distribution.
Data base layer consists of all the data that is required for processing.
The advantage in three tire arch is that even though if there is an error in one application module eg ; like in fi/co it does not effect the other application modules....so it is independent as well as dependent also....
It is also called as a Client-Server Architecture.
First is the Presentation Layer then comes Application Layer n then is the Data base Layer.
Dialog Server acts like an Interface between Presentation Layer n Application Layer.
Update Layer acts like an interface between Application Layer and data base layer.
So these r the main points in SAP R/3 architecture.
if useful reward with points,
with regards,
madhuri.

What is meant by costing key?

Dear Experts ,
while releasing the billing document to accounts , i am getting error like
Valuation with material cost estimate: error, The system looked for the material cost estimate using costing key "002", as defined in the Customizing settings for CO-PA, incomplete due to FI/CO interface
what is meant by costing key?
regards
rajakarthik

Hi,
In Costing based Profitability analysis you define costing keys. A costing key is a set of access parameters which are used in valuation to determine which data in Product cost planning should be read. In the costing key you attach the costing variant.
In the costing key you specify whether the system should read the current standard cost estimate, the previous standard cost estimate or the future standard cost estimate or a saved cost estimate.
The configuration settings to determine this costing key is as follows:
Assign costing keys to the products u2013 Three costing keys can be attached to a single product for a specific point of valuation, record type, plan version.
Assign costing keys to Material types
Assign costing keys to any characteristics u2013 You can use your own strategy to determine the costing keys. This is through user defined assignment tables.

Dispute Case Key (Replicated) (0DPM_D10); what is meant by Replicated?

Hi everyone,
I am working on implementing FSCM Dispute Managment module. I have some questions regarding the new standard content provided by SAP for this:
Earlier I have seen clients using the Stanadard InfoSet 0DPM_I0 for all the Dispute's reporting as it combines data from AR, Dispute Case key and 0Customer. But now I am seeing a bunch of new objects like 0DPM_M10, 0DPM_M20, 0DPM_C10, 0DPM_D10, 0DPM_DCAS_10 etc. provided by SAP as standard content.
Does any one have any experience with this new content; can anyone explain me how this new content is useful. My client is reluctant against using the standard InfoSet as its is built on two DSO's; I have suggested to build a cube on top of them and can still use an InfoSet to combine AR line items, Disputes, Dispute case key and Customer. Correct me if I am wrong with thid statement.
Also please let me know what is meant by a Replicated DSO.
Any comments or suggestions will be greatly appreciated.
Thanks & Regards,
SRV

There are a few things to consider:
 1) The data is stored in deserialized form until it is read. The first read will deserialize the data.
 2) There is some overhead per-entry. 750MB/(3,000,000-30) = ~250 bytes per entry. Some portion of this is attributable to the per-entry overhead.
 3) How did you measure memory usage? Usually invoking <tt>System.gc()</tt> before measuring heap usage will clear garbage but is not guaranteed.

What is meant by criteria of Updateability in MDM Import manager

Hi,
What is meant by criteria of Updateability in MDM Import manager? i read some information, but i could understand, it says original data source be updateble. what is meant by Original data source.?
what is the use of option "Read-only" in Import manager logon screen.
Thanks

Hello Ankam,
You can check the Read-only option to prevent MDM from updating your data source.
Kindly see the below information on "DATA SOURCE UPDATES"
DATA SOURCE UPDATES
Some MDM Import Manager operations require that the original data source be updateable, thereby allowing new fields and/or entire new tables u2013 and the corresponding data values for each record u2013 to be automatically added to the data source before further processing.
Other operations simply create virtual fields in the MDM Import Manageru2019s workspace, although if the data source happens to be updateable, some of these operations instead add the new fields to the original data source as well.
NOTE ►► Updating the data source when possible allows you to
perform additional operations on the new fields as if they were part of
the original source data, and also use them as record matching fields.
NOTE ►► Fields that are added only if the data source is updateable
can be deleted automatically by the MDM Import Manager when you
exit or switch data sources based on the setting of the Delete Created
Fields on Exit configuration option.
Updateable Data Sources
Whether or not a data source is updateable depends upon the following:
u2022 Source type. The source Type must permit the MDM Import Manager to update its schema and insert the additional fields of data; some supported types are updateable and some are not.
u2022 Media. The media on which the data source resides must itself be updateable. If the media on which the data source resides is readonly, such as a CD-ROM, the data source cannot be updated.
u2022 Permissions. You must have the proper file system permissions to update the file, or the proper DBMS permissions to update the schema of the database.
u2022 Read-only option. You cannot have checked the Read-Only option, which prevents MDM from updating the data source even if the other conditions would otherwise permit it.
NOTE ►► The Read-Only option is: (1) enabled for source types that
can be updated (Access, Oracle, SQL Server, and XML); (2) disabled
and unchecked for those that use Access as an updateable staging
area (Delimited Text and Fixed Text); and (3) disabled and checked for
those that cannot be updated (Excel and ODBC).
NOTE ►► When the data source is SQL Server, the table names in
the database must not contain spaces; otherwise any operation that
would update the data source will fail.
Hope this helps.

Vikas

What is the best resource for Discoverer novice.

I need direction in this tool. what is the best resource for me to use.

Hi Ade
You could do a lot worse than get hold of a copy of the Oracle Discoverer 10g Handbook that I wrote. It will walk you through much of what you need to know. You can find it on amazon.com or via a link from my website: http://learndiscoverer.com/books/books.htm
Another good resource would be a training class in either the Admin tool or End User tool or both. Oracle Corporation offer excellent training as do many other companies, including mine. Just google Discoverer Training.
Further resources are the Oracle By Example series on the OTN forum. These are free. You will find the Discoverer lessons here: http://www.oracle.com/technology/obe/obe_bi/discoverer/discoverer_1012/index.html

What's a good video cature device?

So I was wondering, what is a good media capture device for
streaming? I'm thinking an external for portability purposes. Also
when I buy one, whats a good software to get along with it? Adobe
Premiere Elements, Sony Vegas+DVD Production Suite? I'm sort of new
to the video side of web design.
Also, if i'm doing HD. Would I have to buy on of those really
expensive ones? Not just the ones for DV. But also, MPEG/HD/HDV
etc.?

I'm also using 1680x1050 on two wide screen monitors on two different nvidia cards. a nvidia7900 and a nvidia6800. Everything works fine. They are set up as independent screens. The third monitor isen't a wide screen and it's on a third card nvidia geforce4. Anyway, if it helps, you can find my xorg.conf file in the wiki. It's the last one in the list.
http://wiki.archlinux.org/index.php/Xor … conf_Files
The only thing I changed in the file since I posted it was the order of the font paths.

What is meant by stacked list

hi
what is meant by stacked list

Hi Jyothsna,
A stacked list is a list used in Module Pool programming.
In an ideal scenario,you will define the screen sequence in either a static or a dynamic way.
By the statc way,you define the next screen and enter the next screen's value in it.
By the dynamic way,you code the statement CALL SCREEN XXX where the XXX means the screen number.The dynamic way overrides the static way of defining the screen sequences.
Now,if you want to insert a screen sequence,i.e a sequence of screens which are not defined in the same ABAP program,you either do it by static or the dynamic way again using the above constructs.
But in this case,a stack is loaded for a screen sequence and the screens are processed based on the sequence defined in it.
Before leaving this screen sequence,you should always destroy or delete it usng the keyword LEAVE as it occupies a lot of memory.
In case you have any further clarifications,do let me know.
Regards,
Puneet Jhari.

What is meant by noted items

hi all,
can any one explain me what is meant by noted items incase of G/l ,AR & AP. as i found this word in FBL3N ,FBL1N & FBL5N also?
thanks in advance...
regds,
raman

Hi,
Unlike manual accounting, you can make certain transaction in SAP which don't have a impact on accounting but are necessary for dicision making or related to any future transactions. These are called Noted items. Noted items are only posted to one side of accounting.
Eg: If we send a request to customer for down payment, it is not a business transations and have no impact on accounting, but we can pass a entry in SAP for such transaction and it will be a noted item. When actual down payment is received, this noted item is cleared.
Reward points if answer is helpful.
