• Code of script to the code for the class paper - best practices

  I'm starting to put my code in the document class, instead of on the main timeline, and I have a few questions. When I was using the timeline, everything was linear. It is easy to know what things would begin and end because of the way the playhead moves. With the document class, I noticed for the first time that the functions are performed at the same time, if you call one after the other. What would be the best way to make them run in the order? Let's say I have the functions f1, f2, and f3. I guess at the end of the f1, I could call f2 and at the end of f2 call f3 or use event listeners, but is it the right way to do it? At the time wherever you arrive at f3, are not always 'open' because they did not complete f1 and f2?

  do you want some significant time to sweat between execution of the f1, f2 and f3?

  If so, use a timer or a timer.  If not, then just call sequentially. with a few exceptions (mainly when loading some outside (flash) file synchronously executes the code):

  F1();

  F2();

  F3();

• Best Practice Guide for stacked N3024 switches

  Is there a guide to BP for the configuration of the 2 N3024s stacked for the connections to the server, or is the same eql iscsi configuration guide.

  I'm trying to:

  1) reduce to a single point of failure for rack.

  (2) make good use of LACP for 2 and 4 nic server connections

  (3) use a 5224 with it's 1 lacp-> n3024s for devices of unique connection point (ie: internet router)

  TIA

  Jim...

  Barrett pointed out many of the common practices suggested for stacking. The best practice is to use a loop for stacking and distributing your LAG on multiple switches in the stack, are not specific to any brand or model of the switch. The steps described in the guides of the user or the white papers generally what is the recommended configuration.
  http://Dell.to/20sLnnc

  Many of the best practices scenarios will change of network-to-network based around what is currently plugged into the switch, and the independent networks needs / requirements of business. This has created a scenario where the default settings on a switch are pre-programmed for what is optimal for a fresh switch. Then recommended are described in detail in white papers for specific and not centralized scenarios in a single document of best practices that attempts to cover all scenarios.

  Express.ypH N-series switches are:
  -RSTP is enabled by default.
  -Green eee-mode is disabled by default.
  -Frother is enabled by default.
  -Storm control is disabled by default.

  Then these things can change based on the towed gear and needs/desires of the whole of society.

  For example, Equallogic has several guides that recommendations of configuration detail to different switches.
  http://Dell.to/1ICQhFX

  Then on the side server, you would like to look more like the OS/server role. For example a whitepaper VMware that has some network settings proposed when running VMware in an iSCSI environment.
  http://bit.LY/2ach2I7

  I suggest making a list of the technology/hardware/software, which is used on the network. Then use this list to acquire white papers for specific areas. Then use these white papers best practices in order to ensure the switch configuration is optimal for the task required by the network.

• Design by using NetApp's best practices

  I am preparing for my VCP5 and I read the new book by Scott Lowe. the book describes how the traffic should be isolated. your vMotion, vmkernal, etc., but in many organizations, I see the NetApp with some of data warehouses and a few LUNS to CIFS share LUNS. I guess you can have your vmMotion on a VLAN separated, but would not safer just configure a windows VM file server to host your files? In freenas and openfiler forums, they stress is not to run their software in virtual machines in a production environment.   Physical separation would be better then just a VLAN? I was inking and correct me if I'm wrong. I think the CIFS shares in a virtual hosting machine would SAN, vMotion, vmkernal, most reliable if you have redundant switches on both sides VMware hosts. So if your kernel switches drop your vmware environment will not drop.

  > traffic must be isolated.

  Yes, the network traffic must be split on networks separated for various reasons, including performance and safety.

  > NetApps with MON a few for data warehouses and a few LUNS to CIFS share.

  Yes, if you have a NetApp file server you can block-level storage server as FCP or iSCSI, CIFS or NFS file-level storage.

  > I guess you can have your vmMotion on a VLAN separated, but would not safer just configure a windows VM file server to host your files?

  OK, you lost me.  Yes, you must separate the vMotion traffic to enhance the performance and because the vMotion traffic is not encrypted.

  I don't see where you're going for vMotion to a Windows file server?

  However, if you are referring to, why don't you your NetApp instead of Windows CIFS Server:

  You don't need to patch and reboot the NetApp at least once a month.

  Performance is better

  You don't need to buy a Windows license and then maintain Windows

  Snapshots.  NetApp has the best shots in the business.  When your Windows I/O high, or just typing box because it of Tuesday and removes all of your VSS snapshots you really wish you had a NetApp.

  > In the forums of freenas and openfiler, they stress is not to run their software in virtual machines in a production environment.

  Note that there are a ton of storage there equipment running as VMs and server NFS for shared storage, including left and they have been stable for years.

  > Physical separation would be better then just a VLAN?

  Yes, if you have the infrastructure.  When it comes to the first time I've seen reference you VLAN?  Are you talking about now the NetApp as the series 2020 with two network cards where you need to carry all traffic (managent, CIFS and iSCSI) through them via VLAN?

  Like this: http://sostechblog.com/2012/01/08/netapp-fas2xxx-fas3xxx-2-nic-ethernet-scheme/

  > I was inking and correct me if I'm wrong. I think the CIFS shares in a virtual hosting machine would SAN, vMotion, vmkernal, most reliable

  CIFS is nothting to do with SAN, vMotion or VMkernel.  CIFS (SMB) is the protocol used mainly by Windows file sharing

  > If you have redundant switches on both sides of the VMware hosts. So if your kernel switches drop your vmware environment will not drop.

  You always want to redundant switches.  No single point of failure is the best practice.

• Best practices for retrieving a single value from the Oracle Table

  I'm using Oracle Database 11 g Release 11.2.0.3.0.

  I would like to know the best practice to do something like that in a PL/SQL block:

  DECLARE
    v_student_id    student.student_id%TYPE;
BEGIN
    SELECT  student_id
    INTO    v_student_id
    FROM    student
    WHERE   last_name = 'Smith'
    AND     ROWNUM = 1;
END;

  Of course, the problem here is that when there is no success, the NO_DATA_FOUND exception is thrown, which interrupts the execution.  So, what happens if I want to continue despite the exception?

  Yes, I could create a block nested with EXCEPTION section, etc, but it seems awkward for what seems to be a very simple task.

  I've also seen this handled like this:

  DECLARE
    v_student_id    student.student_id%TYPE;
    CURSOR c_student_id IS
        SELECT  student_id
        FROM    student
        WHERE   last_name = 'Smith'
        AND     ROWNUM = 1;
BEGIN
    OPEN c_student_id;
    FETCH c_student_id INTO v_student_id;
    IF c_student_id%NOTFOUND THEN
        DBMS_OUTPUT.PUT_LINE('not found');
    ELSE
        (do stuff)
    END IF;
    CLOSE c_student_id;   
END;

  But it still seems to kill an Ant with a hammer.

  What is the best way?

  Thanks for any help you can give.

  It depends on what you want to do.

  You expect only 0 or 1 rank. SELECT INTO waiting for exactly 1 row. In this case, SELECT INTO may not be the best solution.

  What exactly do you do if you return 0 rows?

  If you want to set a variable with a NULL value and continue the treatment, Frank's response looks good, or else use the modular Billy approach.

  If you want to "do things" when you get a line and 'status quo' when you don't get a line, then you can consider a loop FOR:

  declare
    l_empno scott.emp.empno%type := 7789;
    l_ename scott.emp.ename%type;
  begin
    for rec in (
      select ename from scott.emp
      where empno = l_empno
      and rownum = 1
    ) loop
  l_ename := rec.ename;
      dbms_output.put_line('<' || l_ename || '>');
    end loop;
  end;
  /
  

  Note that when no line is found, there is no output at all.

• Oracle BPM 11g - a book, resource on best practices?

  Hello all, I need start an application with Oracle 11g BPM, for this I need to read best practices to run this kind of implementation, integration ADF 11 g / BPM 11 g, is there a book or resource online to talk about this?, please if you know all the resources, please comment.

  Hi Carlos,

  You've probably seen these but my top 3 books of 11g Oracle BPM would be:

  1 getting Started with Oracle BPM Suite 11 GR 1 material - A Hands on Tutorial - what is very well written and I think is the best for new people to start.  I love that it covers the entire suite in depth.  The instructions are clear and well written, but get a bit dated (it was written for the PS3 and we're currently on PS6).  This also covers the basics of the integration of the ADF you're looking for.

  2 oracle BPM Suite 11 g: Advanced Topics BPMN - Mark Nelson has been one of the authors on this.  Anything by mark, I will read.  This book fills in some areas that are difficult to learn yourself.

  3 oracle Business Process Management Suite 11 g Handbook - a little misread in some places, but has more information and best practices in some areas.

  Hope this helps,

• NetApp Best Practice and independent labels

  Hi, Best practices for VMware NetApp recommends, transitional and temporary data such as comments

  pagefile operating system, temporary files and swap files, must be moved to another disk virtual one

  different data store as snapshots of this type of data can consume a large amount of storage in a very short time

  
  
  

  high time due to the rate of change (that is, to create a data store dedicated to transitional and temporary for all VMS data without other types of data or VMDK residing on it).

  NetApp recommends also configure the VMDK residing in these stores data as "Independent persistent" disks in vCenter. Once configured, the transitional and temporary data VMDK will be excluded from the VMware vCenter snapshot and copy snapshot of NetApp initiated by SnapManager for Virtual Infrastructure.

  I would like to understand the impact of this best practice - can anyone advise on the following:

  • If the above is implemented:
    
    
    • Snapshots will work via vcenter?
      
      
    • Snapshots will work via the Netapp Snapmanager tool?
      
      
    • The snapsot includes all of VM disks? If this is not the case, what is the consequence of not having the whole picture of the VM?
      
      
    • The snapshot of vcenter can restore ok?
      
      
    • Netapp snapshot can restore ok?
      
      
  • What impact the foregoing has on the process of return if using a backup product that relies on snapshot technology?
    
    

  Thank you

  
  
  
  
  
  

  Hi Joe

  These recommendations is purely to save storage space when the replication or backup.

  For example, you can move your *.vswap (VM swap file) file to a different data store. NetBackup can do instant IVMS of the warehouses of data and with this configuration, you can exclude this particular data store

  This is also true if you create a data store dedicated for OS Swap files, mark independent so that vCenter not relieve these VMDK.

  I did a project with NetApp on boxes of SAP production

  We moved all the files in *.vswap to warehouses of data created and dedicated RDM for the OS Swap locations

  We actually used the SnapDrive one NetApp technology to suspend the DB SQL on the ROW before the ROW is broken, but I won't go into too much detail

  To answer your questions (see the comments in the quote)

    • The snapsot includes all of VM disks? If this is not the case, what is the consequence of not having the whole picture of the VM? -No. - *.vswap file is created when the VM is started (no need to backup)

  -OS Swap VMDK of location must be re-created in the case of restoration. WIndows will be

  always Prime if the Swap disk is missing, and you specify the new location of swap.

  • What impact the foregoing has on the process of return if using a backup product that relies on snapshot technology? -These backup products use vCenter snapshots and because the vCenter snapshots works 100% it shouldn't be a problem.

• Best practices installation CARS in two areas of data center?

  Data Center has two distinct areas.
  In each area, we have a storage system and a rac node.
  
  We will install RAC 11 GR 2 ASM.
  
  For data, we want to use diskgroup + DATA, normal redundancy mirrored on two storage systems.
  
  CRS + vote, we want to use diskgroup + CRS, normal redundancy.
  But for diskgroup CRS + vote with normal redundancy, there are 3 LUNS and we have only 2 storage systems.
  In my view, that the third logical unit number is necessary to avoid situations of split brain.
  
  If we put two LUNS to storage lun #1 and the other for storage #2, what will happen when storage faills #1 - it means that two of the three disks for diskgroup + CRS are inaccessible?
  What will happen when all the material in the #1 box fails?
  Is the human intervention: at the time of the failure, which #1 area rises again?
  
  Is there a best practice for configuration 2-zone 2-storage cars?
  
  Joachim

  Hello

  With regard to the vote of the files are concerned, that a node must be able to access more than half of the files with the right to vote at any time (simple majority). In order to be able to tolerate failure of n files in vote, need at least 2n + 1 configured. (n = number of files with voting rights) for the cluster.
  The problem in a stretch cluster configuration, is that most of the facilities use only two storage systems (one on each site), which means that the site that hosts the majority of voting records is a potential single point of failure for the entire cluster. If the storage or the site where the files of n + 1 vote is configured fails, the entire cluster will go down, because Oracle Clusterware will lose the majority of the files.
  To avoid a complete cluster failure, Oracle will support a third vote file on a cheap lowend, standard NFS mounted device somewhere in the network. Oracle recommends the file NFS vote on a dedicated server, which belongs to a production environment.

  The white paper below allows you to accomplish:
  http://www.Oracle.com/technetwork/database/Clusterware/overview/grid-infra-thirdvoteonnfs-131158.PDF

  Also with regard to the configuration of the vote and OCR (11.2), when you use ASM. How they should be stored?
