Question about using mixed size disk groups with ASM

I support a 10g RAC cluster running 10.2.0.3 and using ASM. We currently have a data disk group that is 600 Gb in size, made up of 3 individual 200 Gb raw disk devices. The RAC cluster is running on an IBM pSeries server using AIX 5.3
I need to add more space, but the system adminstrator can only give me 100 Gb in the new raw device. What will be the impact, if any, of adding this smaller raw disk device into the same ASM data disk group? I understand that ASM tries to "balance" the overall usage of each raw device. Will ASM still work okay, or will it be constantly trying to rebalance the disk group because the one raw device is only half the size of the other three? Any help and advice given will be greatly appreciated. Thank you!

There will be no impact and ASM will automatically balance the things.

    I have a question about using multiple ipads in our school.  Each of our teachers have a iPad and AppleTV in their classroom.  The issue is, with our classrooms so close in proximity to one another, is there a way to pair teacher #1 iPad to its AppleTV without effecting/projecting onto the adjacent teachers #2 classroom AppleTV?

    Not as such.
    Give the AppleTV units unique names and also enable Airplay password in settings with unique passwords for each teacher.

  • Questions about Mapping GL Accounts to Group Accounts

    Hi,
    I have some questions about mapping gl accounts to group accounts while configuring OBIEE APPS 7.9.6.3 with EBS R12 as a source:
    FIRST QUESTION.-
    For file file_group_acct_codes_ora.csv, I have the following accounts from my customer:
    101101 - Caja Administrativa
    101102 - Fondo Revolvente
    101103 - Caja de Cambios
    101104 - Efectivo en cajero
    This group of accounts is named CASH, now my customer said that this group begins in 101101 and ends in 101199 but in this moment only have this 4 accounts in GL, the rest of the accounts, I mean 101105-101199 are not used right now, they are gonna used in the future.
    So, my question is, in file_group_acct_codes_ora.csv how I need to put this group:
    In this way:
    CHART OF ACCOUNTS ID,FROM ACCT,TO ACCT,GROUP_ACCT_NUM
    50308,101101,101104,CASH
    Or in this way:
    CHART OF ACCOUNTS ID,FROM ACCT,TO ACCT,GROUP_ACCT_NUM
    50308,101101,101199,CASH
    I mean, is there any problem if I use the second way, or is necessary to do it in the first way, and why?
    SECOND QUESTION.-
    For file file_group_acct_names.csv, when I update with a new group of accounts, is there any rule or size boundary for GROUP_ACCOUNT_NAME?
    THIRD QUESTION.-
    For file_group_acct_names.csv, what is the value in column LANGUAGE? I mean, is EBS language?, DB language?, server language?
    I hope that someone can help me, because I need to clarify this and don't do the first full load and this load ends with error because of this.

    I'll take some broad swipes at this and let the smarter people come fill in the details.
    We have a true 1:1 setup in our office and have moved to PHDs as a means of protecting against downtime. The thinking is that we will have a spare machine lying around with our base installation ready to go. If a user's machine fails we'll replace it with the spare machine, let it sync the user directory from the server, and we're back in business. It's no substitute for a real backup system, but it potentially avoids having to run a restore from your backups. It also reduces network traffic compared to plain networked homes, and still lets your users work if the server goes down, but provides the benefits of centralized management. John DeTroye wrote a nice article about this.
    If you've already got data on your "client" Mac you will need to move it onto the server. PHDs will download data from the server to the client on the first sync, but will not upload a complete home directory from the client to an empty directory on the server. You'll find some posts in this forum discussing how people have gone about migrating data prior to that first sync.
    WGM allows you to establish exclusions for stuff you don't want to sync.
    One thing to watch out for in the scenario you describe is the so-called "rabbit effect." Assume Bob uses Mac1 as his primary machine. If one day he logs into Mac2 his home directory will be downloaded to Mac2. Once he returns to Mac1 he'll still be cluttering up Mac2 with his data. If he logs into Mac3 the next day and Tom and Sue are also periodically logging into different machines, you can see how you'll end up with a mess pretty quickly.
    Hope this helps.

  • How to increase size of a Disk Group in ASM?

    Hi,
    I'm testing the ASM in AIX. I created a Logical Volume with size is, e.g., 10G. Then I assign this LV with a Disk Group in ASM. Now I increase the size of the LV using AIX's smit, e.g., to 20G. How can I increase the size of my Disk Group in ASM?
    I understand that Oracle recommend to assign a whole physical hard disk to a Disk Group in ASM.Thus, the resize command of ASM can only reduce the size of Disk Group, but cannot increase the size of it?
    Any advice?
    Pham

    Disk Group is a logical term, phyical size of a diskgroup is determined by the disks belonging to a diskgroup. So you cannot increase a diskgroup, only the disks in it. You can resize a disk up to its physical limit (resize option of ALTER DISKGROUP statement).

  • Hi, I have quick question about use of USEBEAN tag in SP2. When I specify a scope of SESSION for the java bean, it does not keep the values that I set for variable in the bean persistent.Thanks,Sonny

     

    Make sure that your bean is implementing the serializable interface and that
    you are accessing the bean from the session with the same name.

  • Question about using new battery in old Powerbook

    I have a pre-intel Powerbook G4, and the battery is pretty much toast (lasts about 15 minutes now). I have ordered a new battery for it, and I have this question about using it:
    Am I smarter to keep the new strong battery out of the PB most days (as I usually work with it plugged in at home) and just pop it in when I know I will be out surfing on batteries? Or is it just as good living in my laptop 24/7 and only occasionally being called upon to do its job?
    Current bad Battery Information below:
    Battery Installed: Yes
    First low level warning: No
    Full Charge Capacity (mAh): 1144
    Remaining Capacity (mAh): 1115
    Amperage (mA): 0
    Voltage (mV): 12387
    Cycle Count: 281
    thanks folks, Shereen

    Hi, Shereen. Every Powerbook battery wants to be used — drained and then recharged — at least every couple of weeks. If you've always used your Powerbook on AC power nearly all the time, and not followed that pattern of discharging and recharging the battery every week or two, it's possible that your use habits have shortened the lifespan and prematurely diminished the capacity of your old battery. Of course it's also possible that your battery is merely old, as a battery's capacity also diminishes with age regardless of how it's used. You didn't say how old the battery is in years, so this may or may not be an issue. I mention it only because it can be an issue.
    For general information on handling a battery for the longest possible lifespan, see this article. My advice on the basis of that article and long experience reading these forums is that it would be OK to do as you propose, but I doubt that you'd derive any significant benefit from it. You would still want to be sure of putting the new battery through a charge/discharge cycle every week or two, even if you didn't have a reason to use the Powerbook away from home or your desk, because sitting unused outside the computer is just as bad for a battery as sitting unused inside it. And you should never remove the battery from your computer when it's completely or almost completely discharged and let it sit that way any longer than a day or two.

  • Question about using TVARV in an ABAP program

    Hello gurus, Im sorry about the silly question.
    I have a question about using TVARV in an ABAP program.
    A program is presenting a problem and I think that in this code:
    SELECT SIGN OPTI LOW HIGH
      FROM TVARV
      INTO TABLE R_1_163431035_VELOCIDADE
      WHERE  NAME = '1_163431035_VELOCIDADE'
      AND    TYPE = 'S'.
      IF ZMM001-VELOCIDADE_B   IN R_1_163431035_VELOCIDADE AND
          ZOPERADORAS-OPERADORA = 'ABCD' AND
          ZMM001-MATERIAL       IN R_1_163431035_PRODUTO.
      ELSE.
      ENDIF.
    What happens is that the value "ZMM001-SPEED" B not exist in "R1_163431035_VELOCIDADE" but the program executes commands under the IF and not under the ELSE, as I imagine it would work. Is this correct ?
    I am new to ABAP programming, but I have a lot of XP in other programming languages ​​and this makes no sense to me.
    Anyone know where I can find some documentation of the use of "TVARV" in ABAP programs?
    I search the Internet if other programmers use TVARV this way, but found nothing, which leads me to think that was a quick and dirty solution that used here.
    If this is a bad way to program, what would be the best way?
    Regards
    Ronaldo.

    Hi Ronaldo,
    But in this case, the range is not empty, there are 17 records, in this way.:
    For the column "SING" all values ​​are "E"
    It means that the result is false if ZMM001-VELOCIDADE_B has the same value as one of the 17 records (E = exclude).
    For instance, if it has value 'C' and one of 17 records matches C, then the result is false.
    The "IF" with "IN" using "TVARV" as used in the program of the post above has the same behavior of a selection screen?
    Yes, the same behavior as the selection criterion to be exact. You can press the help key in the complex selection dialog for more info.
    I know it's a silly and very basic question, but other language that I used, only the SQL has the "IN" operator, but I think they work in different ways, so I would like to understand how it works in ABAP.
    Not silly ;-). Yes they work differently.

  • Question about using 10g/11g and APEX ...

    Hi,
    I just recently learned of Oracle's APEX and have a few questions about using it.
    Can I use APEX with express, standard, and enterprise editions of 10g and 11g?
    Are all of these free to use?

    You might want to read about APEX rather than jumping into questions that are reasonably well documented. Info at http://www.oracle.com/technology/products/database/application_express/index.html
    Your specific questions:
    1) Apex is a package that can be installed into any properly licensed database.
    2) The price for the production license of the database varies by edition.
    The price for Express Edition is $0 for use in production. Part of the cost for that edition is 'no Oracle Support based support, no patches, data volume limitation, etc.'

  • Question about using Runtime.getRuntime();

    hi all
    i have a question about using Runtime.getRuntime(). if i use this to get a runtime reference to run an external program, is it considered as starting a new thread inside the thread that starts it?
    is it safe to do it in the Session EJB? if not, what can you recommand to do it? thanks

    hi all
    i have a question about using Runtime.getRuntime().
    if i use this to get a runtime reference to run an
    external program, is it considered as starting a new
    thread inside the thread that starts it? No. Starting a process, starts a process. Threads have nothing to do with it.
    is it safe to do it in the Session EJB? if not, what
    can you recommand to do it? thanksSo what? Run another process? If you want to run another process in java then your choices are to use Runtime.exec() or use JNI. And using JNI will probably end up doing exactly the same thing as Runtime.exec().
    "Safe" is harder. Typically to correctly use Runtime.exec() you must use threads. And as noted threads ideally should not be used. You can use them but if you do you had better understand why they didn't want you using them in the first place. You had also better be sure that you really want to wait for it to complete.
    Other than that Runtime.exec() is safe because it can't crash the VM like other interfaces can (like JNI.)

  • Question about Using PAPI Web Service in PowerBuilder 9

    Hi, all.
    I Have a simple question about using papiws in power builder 9.
    In pb9, I created a new Web Service Proxy Wizard and I input a url for papiws(ex. http://seraphpernote:7001/papiws/PapiWebService) and click next.
    But I couldn't get any Service List.
    In Eclipse, I used this url for using papiws well.
    Does anybody know about this case??
    help me plz.

    IIRC you must activate PAPI-WS for the engine. In Studio you do it by right-clicking on the project, then "engine preferences". In enterprise/standalone you must activate PAPI-WS in the Admin Center.

  • Multiple questions about using iWeb '09 with my Host Excellence, GoDaddy & Storenvy Accounts. Can you Help?

    Hello, my name is Luis Diaz and I have always appreciated the help here in the iWeb community.  I've been using iWeb for a long time. For some reason my usernames are not working lately - LuisDiazArt or RabidArt)
    I updated my domain service with Host Excellence before MobileMe expired and thank you guys for the help with that. So far it's been a flawless service and because of that I'm very happy. I also have all my domains in GoDaddy. They have been very helpful
    Okay I'm going to try to explain my current problem. I'm trying to create a subdomain in GoDaddy for my website: LuisDiazArt.com
    I went and added a Subdomain in the Control Panel as: store.LuisDiazArt.com The subdomain suppose to mask my store: luisdiaz.storenvy.com
    I thought by adding this subdomain it would make all the addresses look similar (and more clean) just in case someone gets lost along the way.
    So what's happening after I waited an hour is I'm getting: http://store.luisdiazart.com/LuisDiazArt.com/Art_of_Luis_Diaz_%7C_LuisDiazArt.co m.html
    I'm getting the huge and familair long addresses and it is not pointing to my store, but to the homepage.
    Did I do something wrong or do I not understand something fully about subdomains? I thought you can make a subdomain point to another site. Perhaps it can't be done the way I'm thinking about this.
    So to fix this issue I am thinking about making a duplicate website with a different domain name (RabidArt) and mask it with LuisDiazArt (this is site name I use on business card and everything else).  After that make a subdomain with the same: http://store.luisdiazart.com
    Perhaps this may fix the problem.
    So to do this I may need to add another site onto my account (Basic and not Business) on HostExcellence.
    So my other questions are:
    Can I have multiple domains or websites using iWeb on a Basic Host Excellence Account? I checked out a few websites, but couldn't really find out if I can have multiple domains/websites using iWeb on Host Excellence with my current account.
    I do know how to make a new duplicate site, but do you publish it the same way as you would with the regular site or do I have to so something different?
    Hopefully the problem can be fixed not having to do a new site and maybe it was something I did wrong when I added a subdomain.

    To add more domains you need to upgrade your account.
    To have a sub domain for your store you need to create a separate site in iWeb and upload these files to the store.luisdiazart.com folder.
    The files for the main site go in the luisdiazart folder.
    Use an external hyperlink to link one to the other.
