Pool : What is the assigment order ?

Hi,
I do not undersand the assigment order for IP pool, Mac @ Pool, WWN pool....
Sometime it seems logical :
for example : MAC pool 00:25:B5:41:0A:00 to 00:25:B5:41:0A:3F, the server 1_nic1 get 00:25:B5:41:0A:3F, the server 1_nic2 get 00:25:B5:41:0A:2F...
Sometime it seems not logical :
server 2_nic1 get 00:25:B5:41:0A:3D, server 2_nic1 get 00:25:B5:41:0A:0E
I just could see right now on UCS 2.1 we have Assignment order oprtion : Default or sequential
What is the difference ? what is the best practice ?
many thx in advance.
Nicolas.

Come now - Everything has structure & order in the world!
The default (and only behavior pre-UCSM 2.1) order for assigning resources used reverse lexicographic order.  Someone in engineering thought that would be an effecient way to allocate resources, however in the real world its much more valueable to use a sequential ordering without having to calculate it what the order may be.
There's no best practice to use either, however if you want to do any pre-zoning, using sequential you can pre-zone "blocks" of WWPNs ahead of time making your service profile deployment easier.  With the default method unless you calculate the ordering people were having to pre-zone everything cause they weren't sure which values were going to be allocated next.
It's simply a choice of visually predictive ordering vs. calculated ordering.

Robert

  • What's the better order to install OEM + AS + DB

    Hi everbody.
    What's the better order to install on RHEL4 Update2:
    - Enterprise Manager Control Grid (10gR2)
    - Database (10gR2)
    - Application Server (10gR3)
    And about the $ORACLE_HOME?? How to? Each instalation have a separate $ORACLE_HOME??
    Tks!

    Rafael,
    Save the Grid Control as the last installation. The order of Database and Application Server doesn't matter, however I would personally install the database first.
    Please read all Installation Guides' before starting any installations, and follow all pre-requisites stated for RHEL4.
    The Installation Guide's states that all products must be installed in separate ORACLE_HOME. As a matter of fact, the Oracle Installer doesn't allow installing any of these products into an existing ORACLE_HOME.

  • What's the correct order to install OEM Grid Control + DB + AS?

    Hi everbody! I'm getting start on OracleAS and Grid Control.
    What's the correct order to install:
    * Enterprise Manager 10g Grid Control
    * Database 10gR2
    * Application Server 10gR3
    (on RHEL4-Upd2)
    or the order is not important?
    I need have the environment for each oracle software ($ORACLE_HOME, $ORACLE_BASE)? Or install first one, and change the environment and install, change again and install, etc.. ? :)
    Tks!

    Hey Rafael! You only have to use the Grid Control CDS, AS, repository database and grid control software are installed automatically, so you dont have to worry about the order u should have to follow.
    Anyways if u have already installed a database u can use that one as a repository.
    about the enviorment variables i guess u´ll be prompted for just one only directory cause u only need to install the software only one time.
    hope u find this interesting!!

  • What is this Hour Glass Model and what is the best order of dimensions

    What is this Hour Glass Model and what is the best order of dimensions in Essbase cube (Block storage model)

    Dimension order has a huge impact on performance.. The worst case I ever saw was in a pre-sales situation where an outline was thrown together very quickly by someone not experienced with Essbase. A rather small retrieval took 3 minutes despite the fact that there was absolutely no data in the database! Rearranging the dimensions made retrievals instantaneous..

  • What is the evaluation order of Page Items

    I just wonder what the execution order of page item assignments are in the page rendering process.
    Sequence (+ Region), Type of items, more clever by checking dependencies ??
    I couldn't find anything here, or looked with the wrong keywords.
    I just need to know, what reliable assumption to make about dependencies amongst page items?
    Is that visible in the APEX code? A pointer to that would be OK.
    Many thanks

    You can view page components in event order in the App Builder by selecting the Utilities > Page Events view in the page definition, and the actual sequence of runtime events in the debug trace.That was exactly what I was thinking, but that is not the case as far as I can tell. The order which is shown "*Utilities > Page Events*" seems to be the display order, but not necessarily the evaluation order in order to obtain the values.
    I have a database field that is shown much further down in this sequence, but I have a dependent field that is calculated based on this value and is shown before in that sequence.
    So I was wondering whether there is an implied order - possibly based on the Source Type of the page item.
    And to answer the question. There are no other computations or processes ... other than the associated "Automated Row Fetch" related to the database column used in the page items on the page.

  • What Decides the Display Order of Subscribed Address Books?

    I have asked this question before and received no help with it. The people who can help me are people who have at some time or other subscribed to 2 or more Address Books belonging to others.
    Can anyone tell me what decides the order in which the address books I am subscribed to appear in the Groups Column? Obviously they appear below all local groups, but when I subscribe to more than one, I can't work out what decides the order in which they appear in the Groups Column. Its not alphabetical and its not creation order (new ones can appear "anywhere" in the list in my experience) and its not based on what subscribed Address Book is selected at the time I subscribe to a new person's Address Book. Any ideas much appreciated.

    The box to the far right (Settings) provides only for sort by newest or by oldest.  Obviously, a designer who never listens to podcasts via iTunes was in charge.  Yet another demonstration of Apple's growing design sclerosis.
    I'm finding an old version of iTunes to which I can resort.  I use iTunes for podcasts more than commercial schlock -- obviously not in keeping with Apple's business plan -- and there's no advantage to staying with 11.1.  Here's an article from SF Chronicle how to do this (it's a popular article!):

  • What's the proper order of installation/uninstallation for upgrading Elements 12 to 13

    I'm upgrading to PE 13 specifically because it's been made Retina-capable.  Otherwise, I'd wait 3 versions between upgrades.  I'm in the peculiar position of having to upgrade PE 12 on a Mac that's just had it's apps and data/documents moved from another Mac on which PE 12 was originally installed.
    In the past, especially when migrating from one computer to another, I've ended up with files and photos that need to be "reconnected" all the time, presumably because the catalog is using the file paths from the old computer when the path to those photos in the restored catalog on the new computer is different at some point.  With my last migration from one Mac to another, the catalog opened just fine.  I could see all my photos, but just about all of them from the last 12 years needed to be reconnected before I could backup the catalog.  It was impossible, so I went back to the prior computer to make the backup I'll use for PE 13. I'd really like to avoid everything being "disconnected" this time.
    My question is how to upgrade.  I made a backup of the PE 12 catalog, and I'll open that in PS 13.  But should I UNinstall PE12 before I install PE 13 or after I install PE13?
    Should I direct PE 13 to place its catalog in the same folder that PE12 used or a different one?  If the same, should I delete that catalog folder and its contents to allow PE 13 to make its own catalog folder?
    When the program is restoring from the PE 12 backup and asks if I want to maintain the same directory structure as the catalog had, what's the best option???
    I think that anyone using PE for several years will have had to migrate from one computer to another a few times, so my problems probably aren't unique.  I'd sure appreciate tips on how to do it better.

    OK, no further help needed, but I do have questions.  I still have no idea why I couldn't restore from a backup of a PE 12 catalog, but I could not.  I found that those backups did not contain a file named PSE12cat.db, but I still don't understand what was going wrong.
    FINALLY, from the unconverted PE 12 catalog that was already on my new computer, but NOT in the location I wanted to use, I happened on a subfolder that did contain a .db file.  It did successfully convert then, and I'm back in business with my Retina-enabled (yay!!) PE 13.
    I'm sure that that conversion was difficult because of extraneous folders that resulted from so many upgrades and computer migrations over the years.  That's why I wanted to start fresh and let PE 13 create its own folder structure which would be rational from here on.  I just couldn't find a way to do that, but perhaps this current Catalog actually is unencumbered by bad path names for the individual files because it did create a successful backup, albeit it very, very slowly compared to the rate at which PE 12 and prior versions created backup.  But this backup, also, contains no .db file. 
    1 -- Why wouldn't PE 13 convert the Catalog backups from PE 12
    2 -- Why would PE 13 claim that backups were "not valid" when PE 12 validated the Catalogs and reported successful completion of its Catalog backup?

  • What's the best order for mac os x?

    Hello, i was wandering about the best order for the RAM clips (when they're different in size, of course).
    Should i place my little one clip in the lower slot and my big one clip in the upper slot, or the opposite, ...or did mac os x worth about it for the performances to be better?
    Thanks for your comments.

    The slots are very specific about the kind of RAM they can accept. If you simply bought RAM based on the generic spec, you may have bought the wrong RAM. Be sure to buy from a vendor that is specific about your Mac model when asking for RAM. http://www.crucial.com/ has a much better handle than most in giving you the right RAM. The height of the module may affect clearance or heat or bus slewing issues with the logicboard, so be sure to put only the height that was already in the computer. If uncertain, find better instructions that show you. See my FAQ*:
    http://www.macmaps.com/badram.html
    Mac OS X performance is best when you install exactly according to manufacturer spec, and not from some generic spec.

    Hi SigPhil,
    The Max order to analyze control on the Color Map tab specifies the maximum order for which you want an accurate measurement of intensity. The Color Map displays more orders than you select because it uses the additional orders for internal calculations.

  • What's the sort order for podcasts on the shuffle?

    Hi all... Can someone tell me how the iPod Shuffle orders podcasts? I've seen MANY posts saying there's no way to manually sort podcasts on the shuffle (which is crazy IMO), but at least if I know how it's ordering the podcasts that'll help me identify which one is next.
    I added 15 podcasts to the shuffle, and sorting by every category I can find none that matches the order the shuffle places the podcasts in.
    So first question -- what order are the podcasts stored in?
    And second question -- Why the heck did Apple do this? Why can't podcasts just be treated like standard MP3 songs?
    And finally if there's no answer to either of these, is there anyway to get ipodderx to sync to the ipod shuffle? I love itunes, but if it's going to hender my hardware I'll switch to something else.
    Thanks for any help on this, and take care --

    Hi Dean,
    I'm wondering if something's wrong with my podcast, because that's not what happens on mine. For example I have my podcasts in this order:
    NPR Technology
    Haunted New Jersey
    Autumn in New England
    Hometown Tales Podcast
    And even after selecting File then Update iPod and even right-clicking on ipod and selecting Copy to Play Order the order of the podcasts are :
    Haunted New Jersey
    Hometown Tales Podcast
    NPR Technology
    Hometown Tale Podcast
    Nothing I've done sorts the podcasts as they should be sort. Also i set it to not show the ipod unless it's connected, and when I sort the podcasts as I want, Update ipod, and plug ipod, plugging it back in shows the wacky sort order they're stored on the ipod. I can rearrange again, update again, eject and plug back in, and the crazy sort order (not mine) is back.
    Is there something I'm missing????

  • What is the correct order to shutdown and startup RAC system

    anyone please take a look if my order of shutdown and restart is correct.
    This is two node RAC,
    1) srvctl stop database -d db_unique_name
    2)srvctl stop nodeapps -n node1
    3)srvctl stop nodeapps -n node2
    4)srvctl stop asm -n rac1
    5)srvctl stop asm -n rac2
    6)srvctl stop listener -n rac1
    7)srvctl stop listener -n rac2
    8) crsctl stop cluster all
    when I restart RAC, use
    1)crsctl start cluster all
    2)srvctl start listener -n rac1
    3)srvctl start listener -n rac2
    4)srvctl start asm -n rac1
    5)srvctl start asm -n rac2
    6)srvctl start nodeapps -n node1
    7)srvctl start nodeapps -n node2
    8)srvctl start database -d db_unique_name

    Hi,
    1.) I would specify -o immediate. Otherwise your stop of the database can take quite a while.
    2.) Actually nothing else (except the database) needs a clean shutdown. I would simply stop the cluster than with crsctl stop cluster all.
    4.) Also note if you have Voting and OCR in ASM this step won't be successfull (since it can't stop ASM as long as the cluster is running).
    8.) Note that crsctl stop cluster will leave the OHASD running (and also some other processes, check with crsctl stat res -t -init).
    If you need to really stop everything you have to execute crsctl stop crs on each node (they are not clusterwide).
    Startup:
    CRSCTL start CLUSTER ALL should actually bring a lot of things up... but this depends also on what has been stopped (since this is recorded in the OCR).
    But at least ASM and listener should startup automatically (even if they were stopped before).
    So normally it is enough to start the database. But I would not start the database, I would startup the services (which the database services). Because this will bring up the database.
    Otherwise you might end up with a running database, but with no active services.

  • CDHDR date/time fields vs. changenr field - what's the proper order ?

    I have an application where I need to keep track of all the changes on sales orders.  Got it working pretty well, but in production it has the nasty habit of missing some changes ( it runs every 15 minutes and keeps track of the last date/time of an item it picked up ).  What's worse is that if I do a full run from scratch, the missing stuff appears.
    I think my algolrithim is flawed because of the missing things plus I found two entries who's entries look like the following (all in VERKBELEG) - yes, this is REAL data from my production system:
    changenr          udate     utime
    0004520883     2/27/2007     19:20:24
    0004522894     2/27/2007     19:16:31
    Apologies for the formatting - anyways, as you can see - which entry happened first?  Is the changenr field the authority on that or is the date/time fields ?  I have to think it's changenr because of the following:
    1 - changenr is part of the primary key - date and/or time is not
    2 - my program is missing changes
    What's even wierder is that the above two changes were made by the same person - and I have no idea which one they did first.
    bottom line - what determines order of changes ? - field changenr or date/time fields (which are udate and utime respectively).  I thought when I designed this the first time that it would been entry #2 above, but now I'm thinking it's entry #1.

    Tom;
    Thank you very much for the information - I did run transaction SNRO and I see on my dev box that it's buffered ( 10 numbers ).  This then leads to my next set of questions:
    1 - If you have multiple app servers and it's bufferered, where does it buffer ?
    2 - Are the change numbers still in order of the changes ( see #4 below ) ?
    3 - When a change number is buffered - does that mean the entire change is buffered or does that mean that only the number is buffered ?
    4 - If you have multiple app servers with multiple changes - do the changes appear in the database in order of the change numbers or out of order ?  Here's a simple example:
        change 1 - done by app server 1
        change 2 - done by app server 2
        change 3 - done by app server 1
        change 4 - done by app server 1
        change 5 - done by app server 2
    At any point, would I see any change number in the database which has a higher change number than one that doesn't yet exist in a commited form in the database ?  In order words, if I did the read just right, would I see changes 1,3,4 on one read and then 15 minutes later 1,2,3,4,5 ?  The reason I'm asking is because if you want to remember where you last left off, if a change number "appears" later and not in order, tracking the change numbers won't help either.

  • What is the slot order for mixing memory

    I have a new Mac Pro (8 core) and I installed 4 4-gig memory modules (slots 1,2,5,6). I also have 6 1-gig modules that I removed to make room for the 4-gig modules. I thought I could use 4 on the 1-gig modules in the empty bays for a total of 20 gigs. However, when I install the 1-gig modules I get a blinking power light and the machine never boots.
    Am I placing the modules in the wrong slots, or is it not possible to mix modules like this?

    Apple seemed to think mixing wouldn't be a problem, unless the real world is different. Did you follow the placement shown in this PDF? Might still want to try putting in only two 1 gbs though, you'll still have plenty of RAM and, according to this Apple quote,
    "For optimal memory bandwidth, all six memory channels should be used, and memory should be balanced across the six channels.".
    "Populating slot 4 or 8 slightly drops maximum memory bandwidth, but depending on the applications used, overall system performance may benefit from the larger amount of memory".
    http://manuals.info.apple.com/enUS/Mac_Pro_Early2009_Memory_DIMMDIY.pdf
    Shouldn't hurt to try... Per the manual, if your Mac blows up, Apple would have to replace it.
    If you can get all your RAM to completely show up, the 4gb RAM, that's the time to monitor things and test without the added sticks. Once the Mac runs smoothly for awhile and the RAM consistently shows up, then I think that might be the best time to try the other sticks and see what happens..
    Really have to make sure that RAM is seated well, and it wouldn't be a bad idea to do a SMC reset while you're in there. It sometimes unsticks, sticky RAM.
    Good luck.

  • What is the best order to upgrade to Lion after putting in a brand new hard drive in my MacBook Pro? Restore first? or install Lion First?

    I  have a 2008 macbook pro with brand new 500GB hard drive and 6GB new RAM.    My old hard drive is backed up on external drive, via time machine. When the shop put in the new hard drive (there was nothing wrong with old one, it was just stuffed to the brim), they loaded snow leopard from a disk, but I haven't put anything from the old drive back on yet....I haven't even configured my mail and am just reading mail  from ipad and phone these days.
    Question: Should I install Lion before I restore all the old backed-up stuff, or is it important to have anything, ( like maybe preferences)  already on the computer when I download Lion.  I want to be selective when restoring from time machine, because my old hard drive had a lot of ancient software and junk on it that had migrated from every computer we've ever owned, and that is many, many.
    So, I'm just stuck on the best way to proceed.  Also, should I install the latest update for 10.6.8 before I download Lion? I see today that some new updates have become available; java, security, safari, and apple software installer.
    Thanks
    G.T.

    Gaye Thomas wrote:
    But I just read your next post, and  it sounds like you think I should do the back-up first, or am I missing something. I think you are now recommending that:
    1. First I should install Snow Leopard,
    2. do the combo update of 10.6.8
    3. THEN USE BACKUP to restore what I want to carry over to new drive.
    4. Then upgrade to Lion.
    I would restore SL and do the Combo 10.6.8 update. Then use your backup to load back in what you want. Then do the upgrade to Lion.
    So what made you change your mind?
    And, just to say again, the hard drive is completely new.  The shop installed 10.6.8 from the installation CD, and I haven't even configured email.  I'm only using safari.  I just now downloaded 4 updates that software updater recommended.  It now tells me it is up to date.  Is there any reason to do a 10.6.8 combo updater?
    Are you recommending to do the back up BEFORE I install Lion, so that there are some preferences and information about old passwords and certain information that Lion will want to know about?  Will it make my life easier to back up BEFORE I install Lion?
    What changed my mind was your second post. You don't want to carry over everything to the new drive and the install of Lion. You only want selective things and of course your personal files.
    For that I "feel" it best to install SL, Update SL to the most current version, Then selectively restore the parts you want and then install Lion on top of that newest install of SL with the selectively restored parts on the new Hard drive.
    That should give you as clean an upgrade as you can get.
    Of course you could go a completely different route. Make the Lion install USB, Save all your program Install files you want to be installed in Lion along with your personal files. Then Wipe the drive and install Lion clean. Then RE-Install your programs and copy over your personal files.
    That is what I would do as I do not like upgrading to a new OS over the top of an older one. I have never found that to be as clean and it always seems to carry over stuff from the older OS to the new one. But that is me.
