Differences between .profile,oraenv and dbhome files

can anyone tell me the differences between .profile,oraenv and dbhome.
database version is 10.2.0 and OS is solaris 10.
I have set up the environment variables using .profile
is the functionality of oraenva and dbhome same like .profile?

Hello,
oraenv and oracle home_
The oraenv and coraenv utilities both aid in setting the Oracle environment on UNIX systems (other utilities exist on Windows platform that enable the Oracle Home to be set.) The coraenv utility is appropriate for the UNIX C Shell; oraenv should be used with either the Bourne or Korn shells.
Database operations require the ORACLE_HOME to be set before the user may access the database. If ORACLE_HOME is not set, commands such as sqlplus, exp, or any other utility for that matter, will not be found.
Both utilities are shell scripts that do the same thing in the different UNIX shells. They will prompt for a SID of the database unless ORAENV_ASK is set to N. The utility will also append the ORACLE_HOME value to the path, marking the location of the utility.
The oraenv command will prompt for the SID of the database that you wish $ORACLE_HOME to access.
$ . oraenv
ORACLE_SID = [] ? ASG920
The dbhome utility can now be used to verify that $ORACLE_HOME is correct.
$ dbhome
/usr/oracle/9.2.0
The “dot space” part of the command is required to make the environment change with the parent shell, as opposed to entering a command without it which would only affect the subshell running that process.
These commands can be used to avoid specifying the network service name when issuing commands. For instance, without using oraenv, a sqlplus command would look like:
$ sqlplus system/manager@nameofservice as sysdba
whereas after oraenv has been executed, the following command would work:
$ sqlplus system/manager as sysdb
The profile:_*
The Profile file in your home directory is a collection of Korn shell commands that are executed whenever you login. Commonly, the Profile file is used to set environment variables and shell options. You can also put command aliases in your Profile file, but it's better to put them in a separate file -- commonly called .env (which is pronounced: dot-e-n-v)-- that you define and execute in your Profile (which is pronounced: dot-profile).
This document briefly introduces environment variables, shell options, and aliases, and gives sample Profile and .env files.
The commands in this document assume that you're using Korn shell, which is the default login shell on all the ACCC UNIX machines. Shell variables (like $PRINTER and $ENV, which are introduced below) are defined slightly differently in C shell. For example, to select the U-Print system as your default printer in csh you'd use the printer named uprint:
PRINTER uprint
setenv PRINTER

What is the difference between Topic Keywords and Index File Keywords?

What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
RH9.0.2.271
I'm using Webhelp

Hi there
When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
<meta name="MS-HKWD" content="BOFFO" />
When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
Hopefully this helps... Rick

Difference between .jar, .war and .ear file

Hi,
I am pretty new to J2EE technology.
I would like to know what is the difference between .jar, .war and .ear files and how they are deployed on webserver.
Thanks,

Files with a .jar extension or JAR files, are essentially just a collection of files compressed using the ZIP/ZLIB compression format.
JAR (short for Java Archive) files were introduced in the early days of Java as a means to conveniently package and distribute Java applications and components. Since then, a number of additions to the Java platform have followed suit. The introduction of the EAR file is one such addition.
An EAR (Enterprise Archive) file is a JAR file that contains a J2EE application.
A J2EE application is a group of Web modules that collectively perform as a single entity.
A Web Module is an entity consisting of one or more resources such as HTML files, Java class files, XML files, etc. Web Modules are packaged in Web Archive (WAR) files.
Looking at it from a top-down view, EAR files contain JAR files and WAR files. Packaging resources in WAR files, JAR files and eventually EAR files, makes it easy to reuse and reassemble components as new J2EE applications and distribute them to new environments.
For example, Tomcat deals only with WAR files.
So, in order to auto-deploy a Web application to a Tomcat environment, you must place an application's WAR file in the appropriate directory or use Tomcat's deployment tools to manually deploy the file.
If you already have an EAR file that contains the WAR file, you can extract the WAR file and use it as is. If you do not have the EAR file or the WAR file, you can use any number of compliant tools to create the WAR file. Tomcat is a servlet/JSP container available from the jakarta.apache.org site.

Difference between capture rendering and video file rendering

Hello,
I am using JMF to process a video coming from a camera or from a video file, but I noticed some differences in the screen output between these two cases.
I created a Processor and attached an Effect plug-in to its codec chain. On every frame, some processing is done in the process() method of the Effect. Every automatic update of the processor's visual component fires automatic update of my transparent custom drawing pane positioned on top of it (because they overlap). This way I can easily draw some lines over the video layer.
This works fine on capture. When the video comes from a file, however, the JMF visual component always shows the previous frame (not the one just processed), so my drawings are out of sync (they are a step ahead from the frame displayed).
Why is that? The processing code is the same for the capture and the files, only the dataSource is created differently.
Thanks in advance!

What's differences between camera roll and photostream?

what's differences between camera roll and photostream files?

Camera Roll is all photos & videos taken directly with the device, including screenshots, and also any images saved from a text message, email or website.
Photostream is a service that, after you've taken such a photo, after you close out the Camera app (or switch to a different app or your home screen), uploads a copy of that photo via wi-fi to your iCloud Photostream account.
Camera Roll photos are saved until you delete them.
Photostream photos will remain in Photostream for 30 days minimum. After that, they will be automatically purged from the system. If there are photos in your Photostream that you would like to save permanently, copy them to your iPhone's Camera Roll, or download them to your computer using the iCloud Control Panel.

What is the difference between undo tablespace and online redo log files.

what is the difference between undo tablespace and online redo log files. I am confused
as per my knowledge undo tablespace is used to store the undo information when a table is being updated so that, just incase we need to rollback a transaction we know what was present in the table earlier.
when a transaction fails the SMON performs the rollback of the data.
This undo data is stored in the undo tablespace and read consistency if any is enforced.
is my understanding till here correct?
Now, can this undo data/before image not be stored in the redo log buffer and online redolog files?
can redo-log files not store this information?
in fact, is it that when undo tablespaces exist in a database, the undo data/before image is stored in both the undo tablespace and also the redo log files?
kindly clarify my doubt.
thank you.

This question has been asked many times before. The answer is always the same.
Yes, redo contains the before image of data (and the after-image). Therefore, it **COULD** be used to roll back a transaction.
BUT... Redo is written sequentially. Using it to rollback your transaction would involve reading through all the redo written by maybe thousands of other people. It would be painfully slow.
Your transaction is, however, directly linked to just the UNDO that it generates (which is JUST the before image of the data). So, your undo is your undo and doesn't share space with anyone else's undo. Therefore, using it to roll back YOUR transaction is fast.
The fact that undo is only the before image of the data also makes it faster than wading through a sea of before and AFTER images as you'd find in redo. About twice as fast, in fact, since there's half the data. Roughly.
Redo also gets written and flushed to disk whenever there's a commit, 3 seconds are up or too much (1MB, actually) redo gets generated between flushes caused by other factors. Your redo gets flushed when those things happen, even if you haven't actually committed your transaction. And redo logs recycle themselves, meaning that your redo -even if your transaction hasn't been committed yet- can be over-written by later transactions. Try rolling back when that's happened, if redo was the source of your rollback data!
Undo, however, cannot be over-written if the transaction has not been committed. Ever. If you don't commit for three years, there will be three years' undo stored in your database (assuming you had the space, of course!).
I could go on, but that will do. Redo is there fore RECOVERY, after catastrophe. Undo is there for read-consistency (and the occasional change of mind). Two different functions. Two different mechanisms. Each one highly tuned to doing what it does, why it does it, most efficiently and effectively.

What is the difference between httpd.pid and httpd.lock files?

What is the difference between httpd.pid and httpd.lock files?

Hi;
Apache httpd saves the process id of the parent httpd process to the file logs/httpd.pid .
LockFile
Sets the path to the lockfile used when Oracle HTTP Server is compiled with either USE_FCNTL_SERIALIZED_ACCEPT or USE_FLOCK_SERIALIZED_ACCEPT. It is recommended that default value be used. The main reason for changing it is if the logs directory is NFS mounted, since the lockfile must be stored on a local disk.
For example: LockFile /oracle/Apache/Apache/logs/httpd.lock"

Difference between profile and role

Can any explain me the difference between profile and role.
I was given a user Id on ABAP stack of XI.
My profile: SAP_ALL
I was not assigned any roles.
I am not sure if I need different roles or this profile
would serve the purpose.
-Naveen.

Hi Naveen,
Adding to Gus points a few more inputs.
Profiles were the menas of assiging authorizations to users until 4.0 Versions.
Later to the same it was upgraded to the concept of Roles. The crux always remains the same.
Be it a profile or a role, it contains the Auth Object and the respective values.
But in present scenario, you can get confused by the profiles that are assignable to Users.
IN short the following points can be helpful.
1. The profiles like SAP_ALL;SAP_NEW,S_SPO_ALL etc are standard Profiles delivered by SAP which when assigned to a user in his profile in SU01 would get all the related authorizations.
( You must be lucky to have SAP_ALL assigned to ur ID by ur basis guy)
2. A role is created by assigning a few transactions to this role and when this role is generated, it generates a PROFILE. But this profile is a system generated one and cannot be ever assigned to any user. These profiles can be sorted out as they have the standard naming like T-XXXXXXXX where they are the numbers and it can never be assigned to any user.
3. Note prior to 4.0 its all Profiles that are assigned to users and later to the same came the concept of Roles and hence this change.
Hope the answer is helpful in making u undersand a few inputs form my side.
FYI:
Method to create a role can be checked out from the link below.

Differences between PDF (Interactive) and PDF (Print)

What are the main differences between PDF (Interactive) and PDF (Print)?
Now it seems to me that PDF (Interactive) is limited version of PDF (Print).
Any links to read about this topic?
Thank you in advance,
Mykolas

There's actually quite a few differences between (Interactive) and (Print).
Here's a list of pointers written by Michael Ninness (previous product manager of InDesign and now working at Lynda.com) http://www.lynda.com/michaelninness
I just got premission from him to post this (Thanks Michael!):
Here is some info for you regarding what choices are being made under the hood when you choose File > Export > Adobe PDF (Interactive).
Things that just happen or are included, with no choice in the dialog box:
Hyperlinks, Bookmarks, Fast Web view, Compress Text and Line Art, Crop Image Data to Frames.
Things that are not included, with no choice in the dialog box:
Visible Guides/Grids, Hidden and Non-Printing Layers, Hidden and Non-Printing Objects, Marks & Bleeds, No Ink Manager or Simulate Overprint options.
Things that you can choose:
Security Settings, Embed Page Thumbnails, Create Tagged PDF, Create Acrobat Layers, Initial View, Initial Layout, Open in Full Screen Mode, Page Transitions, Image compression and resolution.
Other:
Fonts: Subset 100%
Color Conversion: Destination
Destination: sRGB
Profile Inclusion Policy: Include Destination Profile
Transparency Flattener: No Flattening
And lastly, Compatibility is set to Acrobat 9 (PDF 1.7). This last point is important, and largely explains the main reason we split Interactive PDF out as a separate export choice from Print PDF. When you export an interactive PDF from CS5, included media is now written out to the Rich Media Annotation Layer, which means this content is played back via the embedded Flash Player within Acrobat Pro 9 or Adobe Reader 9 or higher. In previous versions, this content was written out to the Screen Annotation Layer, which meant this content was played back via QuickTime. This has been a long-standing headache for end users as playback across platforms was often inconsistent, would frequently break when Apple updated QuickTime, etc.
Lastly, if you want to include rich media in your interactive PDFs (SWFs, audio and video), the only formats supported if you want to target Adobe PDF (Interactive) are MP3 for audio and FLV for video. Other file formats will need to be converted to these formats before you export to Interactive PDF. For video files, you’ll be able to convert to FLV with Adobe Media Encoder. For audio files, you can use any number for free audio conversion tools, including iTunes.

Difference between config tool and offlinecfgeditor?

I am having a strong confusion between these two. Please help.
Both require the DB to be up.
Both requires a restart after a change, that means none of them makes the change in DB directly.
What is the difference then?
What I think that configtool directly doesn't make a any change at DB level at all, it only changes the instance.properties file at OS level only, whereas offlinecfgeditor changes the values of the parameters at DB level.
Please correct me if I am wrong.
One more doubt:
What is the difference between instance.properties and instance.properties.vmprop?
I know second gets created every time with the restart of the DB. Does that mean it's a copy of DB stored parameters?
Is there a way in JAVA stack by which we can bring the parameters at OS level and DB level in sync, like we do in ABAP in RZ10 by importing the profiles?
Please reply.

Hi,
Basically the configtool and offlinecfgeditor are the same thing, the configtool is more user friendly, but the offlinecfgeditor can be used to access certain files and configurations that the configtool doesn't have access to.
Any changes done in the configtool are made at a database level, the instances.properties only gets changed after the bootstrap process which involves pulling data from the DB, This is the reason the j2ee needs a restart after ant changes are done to DB by configtools as these core DB files (note just the ones that change the instance.properties) are only accessed during the bootstrap phase, (a start up phase). This is to avoid any inconsistencies.
The instance.properties.vmprop just contains information about the jdk in use and other simialar information (used for logs), it will only get created if it does not exist already, hence why it is recommended to delete this file after upgrading the jdk.
The instance.properties contains important paramters used during the start up of the j2ee system.
The java stack only syncs OS and DB parameters during start up time (bootstrap).
Kind regards,
Cathal

Difference between Master Idoc and Communication Idoc.

Can anyone list out the difference between Master Idoc and Communication Idoc?

IDoc (for intermediate document) is a standard data structure for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP's Application Link Enabling (ALE) system. IDocs are used for asynchronous transactions: each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database. Another SAP mechanism, the Business Application Programming Interface (BAPI) is used for synchronous transactions.
Form and content: IDoc terminology
As is often the case with proprietary technologies, SAP assigns specific, object-oriented meanings to familiar terms. When referring to IDocs, the term document refers to a set of data comprising a functional group of records with a business identity. (For example, all the data in a purchase order, or all the profile information of a supplier in a supplier master record.)
A message refers to the contents of a specific implementation of an IDoc; its a logical reference. This differs from a reference to the IDoc itself, which specifies the messages physical representation. Think of it this way: If youre watching a parade pass by, the mayor waving to the crowd from his limousine is the message, and the mayors limousine (which is specific to the mayor) is the IDoc. Youre building a logical object, and the IDoc is both its container and the vehicle that moves it.
The IDoc control record
Each IDoc has a single control record, always the first record in the set. The structure of this record describes the content of the data records that will follow and provides administrative information, such as the IDocs functional category (Message Type/IDoc Type), as well as its origin (Sender) and destination (Receiver) as in conventional EDI
Layout of an IDoc control record
This cover slip format informs the receiving system of the IDocs purpose, and the receiving system uses it to determine the correct processing algorithm for handling the arriving IDoc.
Data records
The data records following the control record are structured alike, including two sections: a segment information section and a data section.
In the first part of a data record, the segment information section describes the structure of the data that follows, for the benefit of the IDoc processor. There is a segment name (like an EDI segment identifier) that corresponds to a data dictionary structure to which the IDoc processor has access. The remaining information is useful for foreign systems, such as a partner companys Oracle system, which has no such data dictionary.
The second part of the record is the data itself, a storage area of 1,000 characters.
Status records
If youve ever ordered a package from a faraway location and tracked its progress using the Internet-based tracking utilities now provided by most major parcel carriers, youre familiar with the list of stops and transfer points through which a package passes on its way to you.
This collection of records is exactly what youll see in an IDoc that has begun its work. Following the data records in an IDoc, status records accumulate as an IDoc makes its way from one point in a process to another.
Typically, an IDoc will acquire several of these records as its does its job. They are simple records, consisting of a status code (there are more than 70 codes, covering a broad range of conditions and errors), a date/time stamp, and some additional status information fields for system audit purposes. In addition, as errors occur in the processing of an IDoc, status records are used to record these errors and the date/time of their occurrence.
IDoc Base
IDocs, as data formatting tools, enable the easy sharing of data between databases and applications within a company as well as being an efficient data courier between companies. Typically in SAP, a database of IDoc definitions exists, to which any application may have access.
This IDoc Base gives all the applications and processes in your company domain the capacity to send, receive, and process a document in a contextually appropriate way, without doing anything to the data. For example, a purchase order IDoc can filter through every process it touches, passing from system to system, accumulating status records to track its progress.
Every department using the data can use it appropriately without any cumbersome intermediate processes, because each department draws its key to interpreting the IDoc from the same source.
Multiple messages
One cumbersome feature of conventional EDI is the embedding of more than one functional record type in a document. The unwieldy X-12 888 Item Maintenance transaction set is an example: It purports to handle so many different configurations of product master data that it is horrifically difficult to integrate into an existing system.
IDocs, on the other hand, handle multiple messages with ease. Given the centralized IDoc interpretation that SAP provides to all its parts, its no problem to define an IDoc that will contain more than one message, that is, more than one data record type.
A customer master IDoc, for example, may contain customer profile information records for a customer with many locations. But it may also contain location-specific pricing information records for that customer in the same document. This is an incredibly efficient way of bundling related records, particularly when passing large amounts of complex information from system to system Records in a multiple-message IDoc

Technical difference between ECC5.0 and ECC6.0

Hi everyone,
Can anybody tell me whats is the Technical difference between ECC5.0 and ECC6.0.

Dear Divya,
When it is a technical upgrade from a lower version to ECC6.0, many objects like includes, Function modules, reports, OSS notes, DDIC objects, BDC/Print programs, SAP scripts, screens will get affected due to the upgradation. So we need to check with all these objects.
u2022 We will encounter short dumps while executing certain programs. This may be due to the usage of obsolete function modules or Unicode errors.
u2022 The BDCs in the upgraded version will become defective as many of its screen field names will be changed during version change.
u2022 Program texts of many programs will be lost. They have to be restored.
u2022 In case of tables, enhancement category has to be provided.
u2022 There is a possibility of losing the variants during upgradation. So care should be taken to retain them before upgradation.
u2022 ECC6.0 is case sensitive, so many of the interface programs will fail to transfer (FTP) files between systems. These objects have to be changed so that the commands passed to the external system be UPPERCASE.
So a developer should be aware of the following:
u2022Unicode programming is followed in ECC6.0. So we need to be aware of it to rectify certain Unicode errors which are likely to occur.
u2022You have to run the transactions SPAU & SPDD to check for list of standard & custom objects that needs modification in the upgraded version.
Check the below link to find more details on usage of SPAU & SPDD transactions

u2022Should be aware of the objects that have become obsolete in ECC6.0. They have to be replaced by appropriate ones.For eg.:
--> The WS_* function modules have been replaced by GUI_* FMs in ECC6.0 as WS_* FMs have become obsolete from 4.7
-->Tables like TVARV & TTREX have been replaced by TVARVC & TTREXN respectively in ECC6.0.
u2022In case of tables, we need to specify the Enhancement category.
u2022Due to upgradation, we will lose out some variants. So we should take a back-up before proceeding with the upgradation.
u2022In case of BDC programs, some field names will be changed. So they have to be named appropriately.
