Another question about indexes

A new requirement for my company is to rebrand our products, including docs. This is pretty easily achieved with variables, but I cannot figure out a way to apply variables to index markers. Did I miss something? Anybody have a suggestion for a work-around? This must come up all the time.

Ruth, if you haven't yet checked out the third party tools for indexing, you might want to browse through the Tool list at
http://www.leximation.com
Most folks who do indexes in FM find that the third party tools add considerable flexibility to the "bare essential" capability available in FM itself.

Yet another question about super raid - GS70

Yes, another question about Super Raid...I recently picked up the cheapest model of the GS70 on newegg which comes with 1 mSata SSD...just a mediocre one if I remember reading correctly. I'm interested in using MSI's Super Raid once my warranty is over with and have been reading a couple posts here:
1. Walk through of how to reinstall OS
--> https://forum-en.msi.com/index.php?topic=167198.msg1224063#msg1224063
2. I'll need a Super Raid card with links to get some, for about $100 each
--> https://forum-en.msi.com/index.php?topic=171722.msg1252847#msg1252847
3. I can't get Super Raid unless it originally came with it?
--> https://forum-en.msi.com/index.php?topic=171185.msg1249640#msg1249640
So what's the bottom line? Would I still be able to enable super raid in the future or am I SOL since it didn't come with it originally?
thanks!

The GT70 CAN come with an adapter that has 2 (on the older, GT70 0NX models) or 3 (on newer GT70 20X models) sockets for mSATA drives. It's an optional part, that takes place of the primary SATA drive in the notebook, and physically has a different part that connects to the motherboard. If it doesn't come with the SuperRaid adapter, then it just has support for a single 2.5" SATA drive.
The GS70 on the otherhand, has this built into the motherboard and there is no swapping it out for a normal 2.5" SATA drive. You can only use mSATA drives (on those ports). The GS70 is meant to be an ultrabook, and therefore does not have the same ability as the GT70 to house up to 2 full size 2.5" SATA drives.
That's really the main difference here. Without physically seeing a GT70 to see how the SuperRaid adapter works, it's slightly difficult to explain.
But in the end, I wouldn't worry about the SuperRaid....The GS70 should have support for Intel Raid Management Engine, in which case that's all you really need.

ANOTHER Question about my iMac G3. Mac OS X and RAM

Hey, I have ANOTHER question about my iMac G3.
I know that I'm supposed to have the latest firmware updates for my iMac G3 running OS 8.1, which I do, but I read some where these firmware updates could only be updated if you're running OS 9.2. Yet when I run the firmware updater, it says my firmware is up to date. I just wanted to make sure this was correct because I just ordered an OS X 10.2 CD today, and I don't want my mac to be "dead" when I install it.
My next question is how much RAM can my mac hold. It's an iMac G3 with a 233 mhz processor, if that makes a differemce.
Again, thanks to the people who have helped me with my first Mac.

hi there--
unfortunately you require system 9.1 or 9.2 for the required firmware update 1.2 for your computer http://docs.info.apple.com/article.html?artnum=86117. so you'll have to install that if you want to install 10.2. it may work for you for a little while, but then you could possibly lose all your information. so i wouldn't advise attempting installing 10.2 without the correct firmware.

Questions about Indexing and Using an Indexing POA

Although I have only about 50 users, at least 15 of them have in excess of 100,000 messages in their accounts and the POA (version 7.0.2) is regularly slowing to a crawl. (I just know that plans for revolution are fomenting!) I have embarked on a campaign to reduce these accounts by archiving everything off to get mail accounts down to 3000 or fewer pieces. I have achieved user buy-in, but have worked on only a few users so far.
In another closely related thread, it was suggested to me that the PO speed issues relate to broken indexes. And I suspect that given so many messages, the indexes were never getting fully rebuilt with the default QF POA settings. I am trying to fix that situation in addition to reducing mail account sizes. So, I have set up a second POA on another server and dedicated it to the indexing task. The /qfinterval is set for 1 hour, other /qf switches at default. The POA-QF does no mail delivery, but it does do nightly user upkeep.
The POA-QF seems to be steadily working away and making progress at reducing the number of unindexed messages. However, I have questions about what I am seeing and what more I can do:
1. Is the progress I am seeing real progress? For example I have a user with over 100,000 messages to be indexed and every time I check the logs, the count drops by about 500 messages per hourly QF cycle. I assume that if I just let it keep running, it will eventually get caught up and fixed. Not only with this user, but with all the others as well. Will my patience (and theirs) be rewarded? Are there any gotchas I need to prepare for?
2. One user has recently had virtually all of her messages successfully moved to archive. I can see them in the Archive, and do not see them in the online account. However, now over a week later, QF still shows >130,000 items still left to index for that user. The POA-QF is making slow, steady progress reducing that number, but why is this user's QF count still so high? Does it just need more time, or is there something amiss for this user?
3. I may want to rebuild indexes for single users from scratch. I have seen the TID 3105742 which tells how to do this: Essentially you turn off mail delivery functions, and make some other switch changes to dedicate the POA to indexing for just a single user, and then you let the POA rebuild the indexes. The implication of that scenario is that the POA is now enjoying exclusive access to the user's databases.
If I want to use my secondary POA-QF to rebuild a user's index from scratch, does the main POA have to be offline and the user out of GWise? That is, Does the QF process require exclusive access in order to rebuild indexes from scratch?
Thanks for any thoughts or suggestions.

Set this switch for this indexing POA - /qflevel=999 - this will index
everything in one run. It will take a long time, but with no qflevel switch you
are indeed only indexing 500 messages at a time, and if the user has that much
mail, it might never really catch up.

This is odd, because really the index count should drop to nothing, but with the
above switch this might get resolved as well.

Not really - the POA is not enjoying exclusive access to the user's database,
the indexer is just avoiding an attempt to index anything else.

No - QF never requires exclusive access. That said, you may find that an
extremely vigorous QF can cause slowdowns for the user.

Question about Index in data selection

Hi experts,
I am reading the documents about index today and find there are some questions confused me. Plz help, thx!
1 What is the technical structure of index?
For example, I have a table ztable with 5 fields, F1(key), F2(key). F3. F4.F5. If I create a index on F3,F4, the system will create a copy of this table. Is the structure of this copy as follow?
F3, F4, pointer(for the lineno of the recorder)
So this copy will have fewer lines than the ZTABLE and is sorted. If the DB optimizer choose this index in selection, it will be fast for the 2 reasons?
2 By what is the sequence of the fields in the index determined? I read a BLOG about permance, the author make a example with DB05, and say if the distinct values of certain field is between 1-1000 lines, it is good to set a secondary index for the field.
I wonder, if the F3 has only 5 distinct value for all the data in the ZTABLE, and the F4 has 100 distinct value. Which one should be the first field in the index and why?
Thx!!~

You seem to be correct for some but not all.
Struture of index will
for unique key index F3, F4, row id of database
it could have only one row id when your where condition match with the index then it goes to only index table first and read the row id and read record directly from the row id.
But for non unique key table store all the F3, F4, row id of record which math value of F1 and F4. It can have multiple value.
When your where condition math with condition partially ie left part of the key or whole part key then read all match record from the index table and then read the database physical table and check for addation where condition if any.
Index is determine on basis of the where condtion which is most left part of index will match.
if your where condition F4 and in your index has f3 f4 then index will not consider, It create gap between index condition and read whole table database. But if you consider f3 then only it consider the index to read because it match the left most part with index fields.
For more details How to create secondary index ? Search for blog in sdn I reply many time.

Another question about gmail

I just posted a question about adding gmail and it was answered. Now, I have another question, I added the new gmail account. It shows in the mail preferences under accounts. Incoming mail addressed to gmail comes to the Archive Box. But I still can't send mail by gmail because in the drop down menu on the email it only lists my other two accounts. Gmail is not an option. I highlighted gmail in the account list and it showed that as the account in use. But, still there was no gmail option on the email form in the sender box. How do I fix that?

You need to look at and read over these very carefully.

Another question about adding music to iPhone

Apologies for yet another question regarding adding music to an iPhone but I am completely stuck.
I bought a new laptop in January (it runs windows 8). I've authorised it and synced my phone to it before. I've used it to add music before.
Lately I've just been buying music directly from itunes on my phone but I wanted to add some music from my older collection that is on an external harddrive.
I've gone through the process of syncing the phone again, which has wiped whatever was on there. I made sure I'd ticked on the "manually manage music" box.
It's put all my purchased music back but it still will not let me drag and drop music from my external harddrive. When I hover over with the file it has "link" but it won't actually send the music to the phone.
Is there a way for me to do this without putting music on to my itunes library? I don't like itunes and I definitely don't want to add the music to my laptop as it defeats the purpose of having an external harddrive! Sorry for such a long-winded explanation.

Just to add... I've now tried adding music to the library (getting desperate here) and it's not letting me do that either. Just says 'link'.
This is the most frustrating thing ever. Why are the simplest of tasks made so difficult? It seems like it only works if you buy the music from the iTunes store.

Yet another question about burners for iDVD 6

It's not my intention to be redundant and the question about which DVD burners are compatible with the most recent release of iDVD has been asked a few times since iLife '06 was released at MacWorld last week. Yet, though Apple has announced it, why have they not posted a list of compatible devices?
Or, is the onus on the manufacturers to certify that their burners are compatible with iDVD 6?
In either case, has anyone determined if this information is available and, if so, where?
Thanks.

Or, is the onus on the manufacturers to certify that their burners are compatible with iDVD 6?
Check with the support sections of the manufacturer's websites - after all, THEY are the ones trying to sell burners.

A question about indexes

When I am at it, I can ask another thing I have been wondering for the longest time.
Sometimes our indexes are 2 rows. Everything works perfectly, except for when the text in the marker is so long that it takes up more than 1 line in the index. I have to manually break the line and add a tab for these lines to look good.
Example:
I want it to look like this:
The only way that can happen is if I go in and manually add the - and the linebreak and then add a tab. It's easy to forget.
Anybody have a solution? Frame 7.2b128

Michael and Johannes.
Thank you both for your answers. Strangely enough I didn't get a notice about you answering my question until now, 3 days after...
Yes, I am talking about TOC. Sorry, English is not my first language. We call it index, so I just wrote that. Johannes solution sounds interesting. Right now I am working on a book without a TOC, but I will look back here and implement your suggestion when I go back to the other book again!
Thanks again!

Another question about a VI I obtained from a NI forum.

The append_column VI attached below has two FOR LOOPs. When this VI is executed The first FOR LOOP executes 10 times as indicated by the CONSTANT 10 wired to the [COUNT] or [N]. My question falls after the first FOR LOOP is complete. How is the second FOR LOOP activated. I thought the [N] had to be wired for the FOR LOOP to execute? In this VI the second FOR LOOP doesn't have the [N] wired to anything so how does it know to execute 10 times which it does?
Attachments:
append_column.vi ‏47 KB

Hi
Actually there is a another way to set the number of times a FOR loop should run, which is illustrated by the VI in question.
Any array input to the FOR loop may used to set the number of times to run. Look at the string array input of the VI, inside the FOR loop the array is not an array anymore, but rather simple strings, this input is set to "Enable indexing". Inside the loop the individual elements of the array is automatically extracted from the array one at a time. I.e the first run of the loop extracts the first element of the array, the second run of the loop gets the second element of the array. The FOR loop will run until all the elemnts of the array has been "read".
You win twice with this design, first, You don't have to know how many times to
run the loop, it will always run as many times as there are elements in the array. Second, You don't have to index the array inside the loop with array indexing tools, it is automatically done by the FOR loop.
You enable / disable this feature by right-clicking the array connection on the loop and selsecting enable/disable array.

Another question about upgrading RAM on G4 iMac

I know that there are numerous threads on this forum about upgrading RAM and I am sorry to have to open another one but, having read many of them, I am still confused!
I have unopened copies of Leopard and ILife 08 that I am planning to install on my 17-inch 1GHz G4 iMac with 768 MB of RAM (256 MB in the factory slot and 512 MB in the user accessible slot). I know that this model does not support all the functions of these programs but I am currently running Panther and the very first iLife so I think it's time for an upgrade!
Apple states that this model supports up to 1GB RAM so I have been thinking that in order to get the best out of the new software I should upgrade to 1GB RAM. My questions are:
1. Do I need to upgrade or is the existing RAM of 768 MB likely to be sufficient?
2. If I upgrade, how easy is it to add RAM to the factory slot? I have searched but can find no instructions on this here or on the Apple website which implies that this is not recommended.
3. Several threads on this forum seem to suggest that, in order to avoid having to mess with the factory slot, it is possible to put 1GB RAM in the user accessible slot and leave the factory slot well alone, resulting in total RAM greater than the maximum recommended by Apple. Is this correct or have I misunderstood?
Thanks in advance.

1. Do I need to upgrade or is the existing RAM of 768 MB likely to be sufficient?
That will probably be sufficient. You could always install and run both Leopard and iLife '08 and see if you feel that they are working OK before buying any RAM.
2. If I upgrade, how easy is it to add RAM to the factory slot? I have searched but can find no instructions on this here or on the Apple website which implies that this is not recommended.
Apple does not post the directions because this is not considered something that a user can do by themselves.
You can see the process at www.xlr8yourmac.com/systems/iMacg4/imacg4takeapart.html
3. Several threads on this forum seem to suggest that, in order to avoid having to mess with the factory slot, it is possible to put 1GB RAM in the user accessible slot and leave the factory slot well alone, resulting in total RAM greater than the maximum recommended by Apple. Is this correct or have I misunderstood?
That is correct. You could replace the 512 MB in the user accessible slot with 1 GB to provide a total RAM of 1.256 GB.

Detail questions about indexes?

We are trying to reduce coherence index heap use in our application using partitioned cache (we use near but it is the partitioned back tier that holds the indexes) and therefore needs to better understandand some details (we are right now using version 3.6 but will eventually change to 3.7 so if any of the answer are different for the two please indivcate that):
1. Are any indexes (or some part of them) maintained per partition (would be my guess since it is possible to efficiently apply PartitionFilter) or are they all per node?
2. Are any part of the indexes in binary form or are both the keys and values in the form of "java objects"?

Thanks for the info.
I got a bit confused about your description of the forward and reverse indexes - I would have assumed that what is referred to as "forward index" would map keys to values provided by the extractor and the "reverse index" map values returned by extractors to possibly multiple keys that have extractors returning this value but it seems like it is the other way around or?!
Hi Magnus,
what you wrote first is correct.
The forward index is a map of internal (binary) keys to extracted values. This has the could be stored in the backing map entry, but I don't think it is done as that would make plugging in index implementation with IndexAwareExtractor much more problematic. Too bad, as it would have been a nice optimization.
The reverse index is a map of extracted values as keys to values of a collection or array (logically a set) of internal (binary) keys of entries the extracted value was extracted from.
So if you have a NamedCache<K,V> and extracted value type is X, then forward index is Map<Binary<K>,X> and reverse index is a Map<X,Set<Binary<K>>> for unsorted indexes and SortedMap<X,Set<Binary<K>>> in case of sorted indexes.
The map and set implementations may differ from implementation version to implementation version.
I don't know what you refer to which would describe it the other way round.
In our case the indexes seem to occupy a lot more heap than the data itself(!!!). That is quite conceivable if you have attributes which can take lots of different values, as in that case the reverse index will also have many entries, each entry value being a set which is not exactly a lean thing either.
It is in particular an index containing information about what cache objects that reference what other cache objects (we use this to answer "where used" questions i.e. what objects contains references to object X) that seem to occupy LOTS of space...
Again, that is lots of different values thus lots of entries in reverse index.
Do you think that your analysis can be easily extended to extractors returning a collection (as is the case for our "gigantic" index) or do they require more investigation?A collection is just a value. If two collections do not equal by the equals() method, then they will have different reverse index entries. It is quite feasible to implement a forward-only index in case you don't need to filter for equality, but you just want to avoid deserialization.
>
With 3.6.1.4 we have done some preliminary tests with different number of partitions and it seems (not fully verified) that it makes a significant difference (fewer partitions = lower index size) so maybe they something has changed from 3.5 (with your analysis I do not see any indication that number of partitions should affect index size or have I missed something to that effect)...
Number of partitions do not affect index size at the moment, indexes are not partitioned in 3.6. (Probably not even in 3.7). The only case when they would influence index size would be if you had partitioned reverse index (and that would make reverse index footprint possibly worse, but definitely not better) analogously to having more nodes causes higher total index footprint.
It is a pity that Oracle don't provide this kind of technical information in the documentation - for a this kind of product it is often essential for developers / architects to have as detailed info as possible...
I don't see what documentation you are really missing. Coherence indexes are instances of SimpleMapIndex which class has a Javadoc. Alexey and I have several times described the structure of indexes on the forum and in the blog. The Coherence book quite aptly describes it. All those descriptions are still valid as index strutures have not significantly changed since 3.0 except that starting with 3.6 you can plug in your own implementation of MapIndex instead of SimpleMapIndex. There was an optimization around 3.5-3.6 time (as far as I remember in one of the 3.5.x patch releases and 3.6) which ensured that you don't have multiple references to the equaling extracted objects (after a request Alexey submitted after one of his blog entries describing index usage), but really that is all, and even that was not a structural change. Semantically, having sparse indexes and forward-only indexes became possible with 3.6 (by plugging in your own implementation), and I don't remember which version introduced not indexing null values which cuts down on size a bit if nulls are frequent and not interesting.
Best regards,
Robert

Question about index in Hana

As far as i know that hana can automatically create a "reverted index" in column table. i also notice in SQL reference guide, that there also "create index" and also we can chage "revert index type (hash/value) " in unique constrains.
so my quesiton is:
1. what is the use case of sentence "create index", whether this index is hana's inverted index or classical DB's index
2. in which case, we should mannually create or build index to replace the one hana automatically create for us.
any hint is very appreciate

Hi Jerry,
Thanks for your response. does Hana create reverted index for each column in one table.
because from one document i catch these words
HANA automatically creates an index for all key columns. Columns with index are marked with ‚Index Type = FULL‛ in the table definition window:
Having an index for all key columns is usually sufficient as queries will typically put filter conditions on key columns. In use cases where filter conditions are on non-key fields and tables have many records, creating an index on this non-key field might improve the performance.
The syntax to create an index is
CREATE INDEX <name> ON <table> (<column>)
i guess it maybe a bit out-of-date, but i am also has 2 questions: (1) what is the key column; (2) how can i found these automatically index generated by Hana
very appreciate your kindly help
Regards,
William

Another question about multiple copies

I've seen several others posting questions lately about making multiple copies, but my question is just slightly different. I'll be making an iDVD project for our 5th Grade Recognition at school. Obviously, I'll be making it on my Mac at home. However, once it's finished and I have my final DVD, I'm going to need to make over 50 copies.
Last year, when I did the presentation as a Powerpoint show, it was easy enough to use multiple (Windows) computers at school to duplicate. There are 4 computers that I used to just rotate CD's in and out of to make copies.
Will I be able to use a Windows machine to make copies of an iDVD disk? I know that the computers can burn DVD's, so that's not an issue. I can't remember exactly which programs the computer have. I believe that one is Sonic something. The one that I used for CD's was IRecordNow (or something like that).
Is there any "protection" placed on the iDVD disk that will prevent me from placing the iDVD into the drive and choosing "copy" in whatever program that I use?

Is there any "protection" placed on the iDVD disk that will prevent me from placing the iDVD into the drive and choosing "copy" in whatever program that I use?
No. Only DVDs made in a production house have copy protection applied.

Another question about smart playlists

Hi,
I have been experimenting a lot with smart playlists lately and have 3 now that I have set up with help from this forum so far. However, I have a question I don't see an obvious answer to. That is, I have every song in at least one playlist, and some songs are in multiple playlists. I can add a playlist to a rule, but how can I tell ITunes to create a playlist containing songs that are in more than one playlist? For example, I want ITunes to create a playlist from songs that are in more than one of the following playlists, top 25 most played, purchased, and tagged. How can I set up ITunes to do this?

The checkmark on the right side when you're editing smart playlists adds more rules. Make as many rules as there are playlist that you're looking into and make each rule say "playlist _is_ (fill in the playlist from the dropdown." If you want songs that appear in ALL the selected playlists you select match ALL of the rules at the top. If you want songs that appear in any of the playlists you've selected you have to select match ANY rule at the top. If you have three playlists and you're looking for any songs that appear on any two of the playlists, but they don't necessarily have to appear on all three, then unfortunately there's no way to do that with one smart playlist. You'd have to make a smart playlist with one saying playlist top 25 most played+purchased (match ALL) another saying with playlist top 25 most played+tagged (match ALL), another saying playlists purchased+tagged(match ALL). Then you could make a 4th smart playlists saying to add the other three playlists and you'd end up with one playlist that has only songs that appear in ANY of the other three.
Note: there's an option that appears to make subrules as if you could do the above all in one playlist but unfortunately these don't actually work the way they appear they should in my experience.
