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

What is the difference between Session timeout and Short Session timeout Under Excel Service Application -- session management?

Under Excel Service Application --> session management; what is the difference between Session timeout and Short Session timeout?

Any call made from the API will automatically be set to the “Session Timeout” period, no matter
what. Calls made from EWA (Excel Web Access) will get the “Short Session Timeout” period assigned to it initially.

What is the difference between Business System and Business Service?

Hi
Please tell me what is the difference between Business System and Business Service...? In real time at what situation we will use Business System and in what situations we will use Business Service..? Please help me
Best Regards
Ravi Shankar B

HI,
Business system:
If you want to address a particular business system as the sender or receiver of messages, choose this service type.
A business system is an actual application system in a system landscape. A business system (service) comprises information about the inbound and outbound interfaces and the software component versions of the business system.
You usually use business system services when configuring internal company processes.
Business Service:
If you want to address an abstract business entity as the sender or receiver of messages, choose this service type.
Using a business service, you can define the technical or business subunits of the companies involved and then assign them the relevant interfaces.
You usually use business services when configuring cross-company processes. In this case, you only make your interfaces known to the business partners involved and either do not make any details about your own system landscape available, or only specific details.
For example, you can define RosettaNet Partner Interface Processes (PIPs) as business services.

Sudheer.

What's the difference between "My Contacts" and "All Contacts"?

What's the difference between "My Contacts" and "All Contacts"?
I have no other account other then my iCloud account (from what I can tell), but "My Contacts" has a significantly smaller number of contacts then "All Contacts".
What's the difference?

Thanks for posting the screenshots, that's helpful. I didn't realize that you were looking at your groups.
"All Contacts" include (as the name implies) all of your contacts. Below that are any contact groups that you may have defined. These would normally be such things as "Work", "Personal", "Doctors", etc.; any groups that you find useful to define. These contain subsets of the "All Contacts" group.
At some point, perhaps inadvertently, you must have created a group called "My Contacts", or imported it to iCloud from your computer. At the time this may have contained all of your contacts and would have had the same number of contacts as the "All Contacts" group. Then over time you probably added 433 additional contacts that were never part of the original "My Contacts" group, resulting in an "All Contacts" group that contained 1465 contacts.
If you don't have any use for the "My Contacts" group, you can delete it by clicking on it on the left sidebar, click the gear icon on the lower left and choose Delete. If you're concerned about doing this, you can make a backup of this group first by selecting it on the left sidebar, clicking on a single contact within the group, pressing Control-A to select them all (they should all be highlighted), then clicking the gear icon and choosing Export vCard. This will create a .vcf file that can later be imported back to iCloud if you ever need to (by clicking the gear icon again and choosing Import vCard).

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 standard,sorted and hash table

<b>can anyone say what is the difference between standard,sorted and hash tabl</b>

Hi,
Standard Tables:
Standard tables have a linear index. You can access them using either the index or the key. If you use the key, the response time is in linear relationship to the number of table entries. The key of a standard table is always non-unique, and you may not include any specification for the uniqueness in the table definition.
This table type is particularly appropriate if you want to address individual table entries using the index. This is the quickest way to access table entries. To fill a standard table, append lines using the (APPEND) statement. You should read, modify and delete lines by referring to the index (INDEX option with the relevant ABAP command). The response time for accessing a standard table is in linear relation to the number of table entries. If you need to use key access, standard tables are appropriate if you can fill and process the table in separate steps. For example, you can fill a standard table by appending records and then sort it. If you then use key access with the binary search option (BINARY), the response time is in logarithmic relation to
the number of table entries.
Sorted Tables:
Sorted tables are always saved correctly sorted by key. They also have a linear key, and, like standard tables, you can access them using either the table index or the key. When you use the key, the response time is in logarithmic relationship to the number of table entries, since the system uses a binary search. The key of a sorted table can be either unique, or non-unique, and you must specify either UNIQUE or NON-UNIQUE in the table definition. Standard tables and sorted tables both belong to the generic group index tables.
This table type is particularly suitable if you want the table to be sorted while you are still adding entries to it. You fill the table using the (INSERT) statement, according to the sort sequence defined in the table key. Table entries that do not fit are recognised before they are inserted. The response time for access using the key is in logarithmic relation to the number of
table entries, since the system automatically uses a binary search. Sorted tables are appropriate for partially sequential processing in a LOOP, as long as the WHERE condition contains the beginning of the table key.
Hashed Tables:
Hashes tables have no internal linear index. You can only access hashed tables by specifying the key. The response time is constant, regardless of the number of table entries, since the search uses a hash algorithm. The key of a hashed table must be unique, and you must specify UNIQUE in the table definition.
This table type is particularly suitable if you want mainly to use key access for table entries. You cannot access hashed tables using the index. When you use key access, the response time remains constant, regardless of the number of table entries. As with database tables, the key of a hashed table is always unique. Hashed tables are therefore a useful way of constructing and
using internal tables that are similar to database tables.

What is the difference between buffered acquisition and non buffered acquisition?

What is the difference between buffered acquisition and non buffered acquisition? How will I decide whether I want buffered acquisition or non buffered acquisition?

I will also add that with non buffered acquisition you have to use software timing. Windows is not a real time OS, so the the timing is not accurate. But if you use buffered acquisition the timing will be controlled with an accurate internal clock on the Daq unit. I think non buffered acquisition should be avoided in most cases.
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

What is the difference between live auction and bid invitation

hi friends
what is the difference between live auction and bid invitation
thanks
regards
vinaykrishna

Source SAP.
BI including Price and non-price variables but LAC Bidding is based on price only.
BI - Longer response time for Bidders (from days to week) but Bidding short bidding windows (Hours).
BI - Bidders sees no information on competitors' bid but in LAC Rank,Best Bid , and next bid can be displayed on real time
BI-Well suited for large variety of goods and services , including ram waterials, services and projects but LAC More suited for commodities or goods and services with standard attributes that vary only slightly from supplier to supplier.
BI -Sourcing is based on value propositions (.eg. High Quality ,fast deliveries) rather than price but LAC market dynamics of auctions work best when buyer/seller relationship is loosele- coupled.

What is the Difference Between Sys Date and Effective Date ??

Hi Gurus,
Can any one pls let me know What is the Difference Between Sys Date and Effective Date ??
with regards
User600722

EFFECTIVE DATE usually refers to a date-tracked record (although not exclusively).
Date-tracked records in Oracle HR have an EFFECTIVE START DATE and an EFFECTIVE END DATE. The record is 'EFFECTIVE' between these dates. In reports, you often use SYSDATE to compare to these two dates to find the CURRENT effective record, e.g. SYSDATE BETWEEN EFFECTIVE START DATE AND EFFECTIVE END DATE.
When you make changes to a HR record, you can choose between DATE TRACKING options, such as CORRECT or UPDATE (there are others too). CORRECT will overwrite the record and replace the data with your changes. This is normally used when you need to correct something that is wrong. UPDATE will create a new version of the record from the EFFECTIVE START DATE you choose. It will also set the EFFECTIVE END DATE of the previous record to the day before your new record's EFFECTIVE START DATE. That enables a history of records to be maintained so you can see what your data looked like at ay one point in time.

What is the difference between full checkpoint and incremental checkpoint?

What is the difference between full checkpoint and incremental checkpoint?
And what is checkpoint queue?
Can someone clarify these concepts?
Thanks!

Hi,
there are different types of checkpoints:
- Full checkpoint:
=> DBWR writes all dirty buffers from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- can be triggered by different events, like a logswitch, a manual checkpoint (alter system ..), a shutdown and so on
This is the setup point for SMON for a crash recovery.
- Partial checkpoint:
=> DBWR writes all dirty buffers of a singel tablespace from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- can e triggered by an ALTER TABLESPACE OFFLINE, ALTER TABLESPACE READ ONLY, ALTER TABLESPACE BEGIN BACKUP statement.
Incremental checkpoint:
number to all file headers and the controlfile.
-- can be triggered by different events, like a logswitch, a manual checkpoint (alter system ..), a shutdown and so on
- Partial checkpoint:
=> DBWR writes all dirty buffers of a single tablespace from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- frequency is determined by FAST_START_MTTR_TARGET parameter (new feature to Oracle 9i), with wich you can specify a time in seconds which SMON is allowed to take maximal for a Crash Recovery until the database must be open again.
Dapending on the system you have SMON must calculate the maximum number of Redolog-blocks which it can manage to recover in the specified number of seconds. It will then create so called incremental checkpoints which will be tracked in the so called checkpoint queue in memory.
FAST_START_MTTR_TARGET is auto-tuned in Oracle 10g and Oracle tries to manage (incremental) checkpoint in a fashion that a minimum of I/Os are caused and a minimum time for crash recovery is needed.
If you set LOG_CHECKPOINTS_TO_ALERT to TRUE you will find checkpoint information in the alertSID.log file. You will see FULL and INCREMENTAL checkpoints then.
Hope this clarifies your question,
Lutz Hartmann

What is the difference between ejb reference and ejb handle?

Hi:
I am newbie for J2EE.
I want to know what is the difference between ejb reference and ejb handle
from the client view and from the container view?
Very Thanks!
Stive

Hi John,,
1) Ejb Object Handle are nothing but a long lived proxy for the
ejb object, using this handle user can disconnect from the Ejb Server/Container
at any time
and after some time using the same handle he can able to resume the conversational
state
with the server / container where he was been disconnected From.
And there are currently two Handles , HomeHandle and Handle for EjbHomeObject
and EjbObject
Respectively. Both these handles have Persistent reference to the EJB Object
2) Ejb Reference is used to lookup a bean from other Enterprise Bean
Ejb reference is a nickname for the JNDI Location that you want to lookup a bean.
your code will looks up a Home object via using this nickname
and the deployer will bind the
nickname to the JNDI location of its choice
EJb Reference are declared in the deployment descriptor

What is the difference between VI Template and vi that is reenterant?

What is the difference between VI Template and vi that is reenterant?
From what little info I can find about them, they seem to basically do the same thing....
What are the difference?
What are the pros and cons of each?
Thanks alot for the help.....

Tarek316 wrote:
I inherited an app that uses .vit for the purpose of having multipe separate instances.
Thanks,
OK, here's what happens when you call a VI Template using Call by Reference or using Invoke and Property Nodes.
Since the VI you are calling is a template, LabVIEW creates a new instance of that VI by creating a copy of it and giving a new name. Notice in the title bar of the instantiated VI the VI name is the same as the template VI plus a number. This is the same thing you see when you open a template from the "New..." menu. So if you call the template VI 3 times, you'd end up with 5 newly instantiated VIs named, "VI Name 1.vi", "VI Name 2.vi" and "VI Name 3.vi". This is how you end up with multiple instances.
Reentrancy only works on subVIs when they are used as a normal subVI in a top level application. Using Call by Reference or Invoke and Property Nodes to open and run a reentrant VI results in the VI only being opened once because LabVIEW will not automatically give it a new name. The new name is only generated when calling templates. Since LabVIEW can only a have a single instance of VI name in memory at a time, you'll not end up with multiple instances.
Not sure if I can help with the know issue on OSX. If it's specific to using the Call by Reference function, you could try calling the templates using Invoke and Property nodes.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

Hi,
Upgrade SAP or Installation of SAP R/3 and ECC
What is ECC? Where to find the installation steps of ECC 5/6.0 with SQL as database and on windows platform with the steps including Solution Manager installation?
http://service.sap.com/instguides
ECC means Enterprise Central Component.
There are all the relevant installation guides. You NEED SAPNet access because without a registered and licensed SolMan installation number you will not be able to generate the SolMan key for the ECC installation.
Upgrade to 4.7
Have you gone through an upgrade to 4.7?
What are the difference or changes associated with 4.7.
If you are currently on 4.6C and are inching forward to upgrading to 4.7 then this information might be useful to you.
There is very little difference between 4.6 and 4.7, the only "steps" you should need are steps in SU25 ( skip step 1) Then go through all your role and perform a merge old new to bring in the new authorization objects
Just to forewarn you of a potential problem which have been encounter at the point of writing.
After updating/ modifying roles in step 2C, when going back into 2C to make sure all roles are now green, 70% have gone back to red!
The maintenance done is ok, but there seems to be a problem while trying to go back into the roles again to re-generate.
SAP recognizes them as needing "adjustment", so you cannot pick them up in mass generate in PFCG as they do not come in, even though the authorizations tab is red.
This problem is currently with SAP and it is confirmed that nothing have been done wrongly.
Generally, the work is quite manageable in the upgrade, but don't be surprised at how big the upgrade is when compared to upgrading from 46b to 46c.
If we have full software of 46c and 47E is it possible to upgrade 46c to 47E or there is a seperate 47E upgrade software need to be requested from SAP?
Where I can get the document with upgrade steps on the service market place?
It is of course possible and supported:
http://service.sap.com/inguides
--> SAP Components
--> SAP R/3 Enterprise
--> (choose your version)
at the bottom there is an "Upgrade guide" for Windows and Unix.
For Upgrades it is recommended to read ALL the notes mentioned in the
upgrade guide and to make sure one is using
- the correct version of the "tp" program
- the correct version of the "R3trans" program
- the correct version of the "R3up" program
All that is explained in the upgrade guide and in the corresponding notes.
If this is your first upgrade you should take a person, that has some experience on doing that for the first time.
Installation of SAP R/3
Currently we are going to install SAP on a new IBM server from the existing COMPAQ server. Where can I get the steps for that.
Configuration is :
   OS - windows 2003 server
   DB - Oracle 9i
   SAP 4.7
http://service.sap.com/instguides
--> SAP Components
--> SAP R/3 Enterprise
--> SAP R/3 Enterprise Core 4.70 / Ext. Set 2.00 (SR1)
--> Inst. Guide - R/3 Enterprise 4.7 x 2.00 SR1 on Win: Oracle
The above url is the SAP Service Marketplace with all the information you need to install, configure and run system. You need to be a valid licensed customer with a user ID and PASSWORD to use that.
