• ORACLE 11g R2 RAC Interconnect latency tuning

  We will address some related to the interconnection of network settings at the level of the OS/HW/VMWare and check if there is a difference in latency for different parameters of interconnection.

  We cannot test in a real production environment. So, we need to emulate the issue of interconnection somehow in our test environment and compare results (latency) for different HW/VM settings.

  Y at - it any way/approach that we can use for testing? For example, to run a script that causes a large number of requests for blocks from one node to another and measure certain parameters.

  What related interconnection parameters/settings, we can check in the Oracle and compare tests for different configurations of OS/HW?

  Ideally, we need to create a test case that we can reuse and compare the results.

  All references are very much appreciated.

  We use the following environment:

  Oracle SE 11 GR 2 CARS of two nodes.

  Windows 2008R2.

  VMWare ESXi6.0.

  Cisco UCS blades.

  Thank you

  When I wrote Oracle RAC Performance Tuning, I devoted a chapter on optimization of the cluster of interconnection. In order to show the impact of some changes on how interconnection has been configured, I used the freely available iperf utility.

  One of the things it's important to know for the Cluster of interconnection is that the device uses UDP. Thus, any tool that you use must be able to send UDP instead of TCP packets. Iperf can do both.

  "For example, to run a script that causes a large number of requests for blocks from one node to another and measure certain parameters.

  One of the biggest problems with this approach is that you have a lot of variables involved. The buffer Cache, of the shared pool, the system drives, etc, etc, etc. With a tool such as Iperf, you can measure just the performance of the network.

  See you soon,.

• Oracle 11g on Windows XP - TCP with SSL

  Hello

  have successfully installing Oracle 11 g on a Windows XP computer that is used as a small server in a test/test environment.

  This machine is running in my local environment without external connections Windows Firewall is disabled.

  A java test program written to connect to the server using TCP / through a connection of plaintext using the driver oracle thin JDBC works very well.

  Wanted now to set up the server so that it would accept SSL connections (ultimately with counterpart, but without authentication server or client authentication as a configuration to boot).

  Used Oracle Net Manager to configure the server as follows:

  (Note: have used red ink hightlight settings I don't know if they are needed)

  For some reason, the server doesn't listen on port 2484 at all (running telnet localhost 2484 on the server itself leads to no possible connection).

  Is not not a network expert I'm stuck here and would appreciate any help on how to overcome this problem of set-up.

  Thank you

  Why a listener 2nd for the TCPS? Why not use a single listener - as is the default value recommended?

  Do you have SSL certificates (root complete auth chain) for the server in the portfolio of Oracle for this server - with the generated SSL certificate request, signed by a root authority?

  To see the server tcp listener endpoints, use the netstat command. Enable SQL * Net follow-up on the side of the listener if you need to trace and debug connections to the listener. Activate too on the client side if you need to trace the calls from the client to the listener.

• How to create a database with SAN storage?

  We are creating a new database, but what we need to do is to configure the oradata, admin and data files directories in SAN disk. In the same system, we have created two database in d drive so we can't change the oracle home

  1 create a LUN on the SAN

  2. mounting LUN on your Windows system

  3. the format of the LUN with diskpart.

  4. at the moment, you can move your database to san lun. This can be done in different ways. For example:

  stop immediately;

  bootable media;

  #move # your files from A to B physically db #.

  ALTER DATABASE FILE RENAME ' C:\oracle\oradata\theDatabase\

  'to' Q:\myDatabases\theDatabase';#rename all files moved

  ALTER database open;

  ALTER database backup controlfile to "/... /... /... /';"

  ALTER database backup controlfile to trace.

  # a full backup (if log mode archive) warm/RMAN or stop again and take a cold backup if no archive log mode.

• Size of a host Vmware with SAN storage

  Hello

  I'm going to host installation 3 V to attach to storage Aray total about 4.5 to, the 3 V host will have a similar hardware Configuration, can I ask:

  • It is best to configure the space of 4.5 TB as a LUN and share with host 3
    
  • Or do the CT 4.5 as 3 separate to 1.5 TB LUN and connect individually.
    

  The performance and wise scalibilty, where is the best.

  Thank you very much

  SM

  I suggest you break into smaller LUNs, as this would also allow you to choose between different RAID levels, for example RAID10 and RAID5. This allows you to optimize the performance of the storage hosting your virtual machines based on the requirements of the particular virtual machine and its workload.

• Oracle 11g Release 2 assumption of raw devices to the CCR

  Hi I need one of my db migrate to 10.2.0.3 for 11g release 2
  now, I got to know that there are some problems with raw devices in oracle 11g R2 rac
  so I want the suggestions of experts
  Thanks in advance

  If you are upgrading a database in place (i.e. without reconstruction, without import-export), Oracle has no other choice than to support the application of raw device.
  However, when you install the Clusterware 11.2 it cannot be installed on raw devices - one is not supported!

• Is it possible to install oracle fail-safe-kind-of (active-passive) SAN replication for oracle?

  Dear Experts,

  Is it possible to configure replication of SAN (active-passive) integrated security for oracle for oracle?

  To get the RTO < 60 seconds

  • If the primary host fails, the remote site should have the option to start the oracle database.
  • Sites are geographically remote.

  SAN storage replication, can it be used in my scenario?

  • I have no option to implement oracle Data Guard as its very expensive.

  Is that what someone achieved something similar with SAN storage replication?

  • I have oracle SE.
  • It is obvious that the all-flash backup can be quick.

  What should be the strategy to have DR site get a few seconds, if the primary site failed for some reason any

  • Daily incremental backup with RMAN. And archive backup runs for every 1 minutes
  • To have the site of DR upward and running within 60 seconds, it still requires too much time to restore the database on remote site and have archive APPLIED setpoint
  • What could be the solution with san replication? RTO is 60 seconds

  Thanks and greetings

  SAN storage replication, can it be used in my scenario?

  I have no option to implement oracle Data Guard as its very expensive.

  --> If you want to use the data that it is free of CHARGE, additional license is not required for normal data guard

  --> additional license is only for the ADG

  Is that what someone achieved something similar with SAN storage replication?

  I have oracle SE.

  It is obvious that the all-flash backup can be quick.

  --> Here, I understand that if oraclle EA is going to be expensive

  --> Again, you can use manual standby

  --> What you are looking for SAN replication, you will need to check with the storage vendor

  --> If your intention is to check with oracle storage, then this may be the correct discussion room

• Deployment of Oracle 11g RAC Release 2 with IBM midsize V7000

  Oracle Grid these days use ASM starts for vote and register files storage. So no need for a cooked cluster file system that must be mounted by all nodes. No need either directly with a gross storage logical unit number.

  ASM uses the LUN of the matrix of storage/SAN directly (as devices of rough blocks).

  Generally however, there are several I/O paths to that LUN on the SAN - in which case there is more than 1 device level o/s for this LUN. Multipath driver s/w addresses this and creates a logical (and redundant) device that sits at the top of several devices of i/o path to the level of the o/s.

  You configure ASM to use devices of paths multiples (as devices of rough blocks) - and applying exterrnal, normal or high redundancy necessary when creating starts on these logical multipath devices.

  The grid s/w and RAC database instances can then use ASM starts as cluster storage.

  This makes storage much easier layer management - and also provide a number of useful features too.

  This is also the approach recommended by Oracle Corp. for RAC - use ASM under the layer of management of storage between storage LUNS in the table and one side and CARS on the other.

• Oracle Rac on San storage

  Hello

  We are at the heart of the definition of a process for installation of 2 node to a san storage device.  Oracle 11.2 on Rhel 5.

  What is the process of implementation recommended for shared storage.

  We want the mirroring to stay at the storage level.

  * NFS without ASM

  * NFS with ASM

  * LUN with ASM

  * LUN without ASM

  All other as appropriate.

  I went through the documentation, it gives options, however, does not tell best practices.

  Thanks in advance everybody and apologize if there is already a post about this and I repeat it.

  The only choice, I will focus on what is LUN (fiber or Infiniband fabric layer) with the ASM.

  And no ASMLib. (optional, not required)

  Set the devices property LUN via udev. Configure logical device for ASM using MPIO.

  I'm going to call any other method, below.

  Florin,

  Make sure that you use the relevent to instructions for your version.
  If you use 4.0 - you probably want the same script - with use of APEX_040000 appropriate.

  See the steps of INSTALLATION of document ITEM.

  http://docs.Oracle.com/CD/E17556_01/doc/install.40/e15513/otn_install.htm#CBHBABCC

  -Make sure that you don't drop the former users of apex framework before update or remove them from the ACL. It can cause you problems.
