• Record number of databases in a recovery catalog

  Hello

  How can register for multiple databases targets unrelated in a unique recovery catalog.

  Suppose I have DEV and TEST databases with different dbid and you wish to register in a single commune RC.

  Kindly advice.

  Thank you

  REDA

  We do this on a regular basis in our shop.

  We will have the DEV and TEST on SERVERA, databases while the catalog RMAN (RMANCAT) is located on server b.

  The entries in tnsnames.ora on ServerB:

  RMANCAT =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SERVERB)(PORT = 1541))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = rmancat)

  )

  )

  LISTENER_RMANCAT =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SERVERB)(PORT = 1541))

  ----------------------------------------------------------------------------------

  The entries in tnsnames.ora on SERVERA:

  LISTENER_DEV =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SERVERA)(PORT = 1551))

  DEV =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SERVERA)(PORT = 1551))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = dev.servera.something.com)

  )

  )

  LISTENER_TEST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SERVERA)(PORT = 1551))

  TEST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SERVERA)(PORT = 1551))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = test.servera.something.com)

  )

  )

  RMANCAT_SERVERB =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = SERVERB)(PORT = 1541))

  )

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = RMANCAT. SERVERB. SOMETHING.COM)

  )

  )

  -------------------------------------------------------------------

  Establish a connection between DEV & RMANCAT - RMAN catalog RMAN is controlled by a user called rmanusr, and each database also has a user called rmanusr.

  RMAN target rmanusr /> @dev catalogue rmanusr /> @RMANCAT_SERVERB

  After have connected you, you should be able to see the information of DBID, to check that you have the right of database:

  Recovery Manager: release 11.2.0.3.0 - Production on Thu Nov 6 11:44:01, 2014

  Copyright (c) 1982, 2011, Oracle and/or its affiliates.  All rights reserved.

  connected to target database: DEV (DBID = 123456789)

  connected to the recovery catalog database

  You should then be able to issue the SAVE command the DATABASE

  ---------------------------------------------------------------------------------------------------------------------------

  Then, establish a separate connection between TEST & RMANCAT:

  RMAN target rmanusr /> rmanusr catalogue @test /> @RMANCAT_SERVERB

  Recovery Manager: release 11.2.0.3.0 - Production on Thu Nov 6 11:44:01, 2014

  connected to target database: TEST (DBID = 987654321)

  connected to the recovery catalog database

  You can now enter a second order SAVE the DATABASE

  When you are connected to one of the connections of RMAN you implemented and after you have recorded the two databases, run:

• The listener is down: even if a listener with the name "AUDITOR", is running on this host at the port: "1521", it has not started using "the target LISTENER. ORA file.

  
  I moved a listener on a host in a House different oracle. The headset works fine, but EM 12 c shows that the listener is down with the following summary:

  The listener is down: even if a listener with the name "AUDITOR", is running on this host at the port: "1521", it has not started using "the target LISTENER. ORA file. CORRECTIVE ACTION: To monitor this "EM listener target" with its current configuration, you must stop the process of listening running and start it using the Listener parameter file: opt/oracle/product/12.1.0.2/network/admin/listener.ora. Alternatively, you can update "this target LISTENER. Location ORA setting"with the location of the listener running, which started using the: opt/oracle/product/11.2.0.3/network/admin/listener.ora.

  EM 11 g, I simply changed the configuration of the listener for the different oracle home, argued the change and in a few minutes the listener would show that 'UP' with the oracle of new home. I upgraded to MS 12 c (12.1.0.4) and can't find how to do this. Can someone give me the procedure.

  Thank you

  Ron

  Hi Ron,

  Can you please do the following?

  -Create a for the listener listener.ora file, stop and start the receiver using the listener.ora file. If the file is located in a default location, set the TNS_ADMIN environment variable to that location before you start the listener.

  -Log on to the EM console, go to the homepage of the listener.

  -In the Oracle Listener menu, select target Configuration > Configuration of the analysis.

  -Ensure that the parameters, including the Listener.ora directory, are properly.

  Kind regards

• not able to run in the host .htm files

  I have downloaded a file .htm on a web hosting account and it just returns a blank page, it works fine on my local machine but didn't run from the host of the site, I can run the .swf directly from the Web hosting account, but it loses its size / formatting, please help

  Hi LocTuanTran,

  In my opinion you download the 'Standard.js' file for the web hosting server. And also the _skin.swf is required to playback your movie Adobe Captivate 2 generated.

• Number of IC & NetMonitor Agents by host

  Get recommendations on the number of IC and NetMonitor of agents that can be run safely from separate servers?  I'm trying to reach to my hardware configuration required for an upgrade of 5.5.8 5.6.5.  Plans are to use IC officers to replace most of the local fglam.  I'll run the hosts supporting the IC and NetMonitor agents on the virtual machines of the suggestions on the configuration of the VM would be appreciated.

  Hi Doug,.

  For the cartridge of the infrastructure, see the Foglight 5.6.2 Infrastructure Management cartridge - OS thread for suggestions/strategy for surveillance of a large number of guests.

  For legacy NetMonitor agent, the maximum limit is 512 devices by agent and is the recommended practical limit of 100 devices per agent according to the alerts when guests are not available.

  You can run several multiple agents by FglAM and FglAMs for each host, so there is some flexibility in terms of whether you want to run more images with few resources, or fewer images with more resources.

  The key factors are:

  -Hosts how do you intend to follow with the agent of IC?

  -How many devices do you intend to follow with NetMonitor?

  Note that the NetMonitor agent will be replaced this year.

  Kind regards

• Number of Virtual Machines in a host

  Dear all,

  I am fairly new with vmware.  As a newbe, I have a lot of request for information on the virtual machine.  As a first step, I have a basic question:

  How we calculate the number of virtual machines that can be installed safely on a host computer.

  For example,.

  The host is with below configuration

  HP DL380 G7, E5645, (6core, 2.4 GHz, 12 MB L3, 80W)

  Dual processor

  48 GB of memory

  8 x 300 GB hard drive

  STD config

  For example, in the configuration above, how WIN2008R2, 8 GB servers can be loaded.

  Is it as 48 / 8 = 6 Machines?

  If so, what is the involvement of CPU cores?

  Your descriptive answer is much appreciated...

  Thanks in advance...

  Welcome to the community,

  This depends on the VM workload. With the material you mention I guess the limiting factor will be the RAM and not the CPU. What is important for this host is have you FBWC attached to the RAID controller to make it work in writeback mode!

  A note more: you will need a licensed version to run ESXi 5.x on this host. The free hypervisor does support up to 32 GB of physical memory.

• Can you connect to a logical unit number after you run a test with RecoverPoint SRM

  Sometimes, when I run a test of the recovery plan that it does not connect to one of my LUN in a RecoverPoint consistency group.  Is there a way I can connect to the LUN when running always the same test?  The same would be true if I would with failover, can I connect to a unit number logic which have not mapped for some reason any after the execution of the recovery plan for the virtual machine online.

  you really need to trigger an SR to see why the lun is not mapped. is the lun of a data store or a RDM vmfs?

  common causes (assuming here all LUNS are in the same consistency RP group):

  -device not picked up by refresh, difficulty because it is to increment the RS parameter to run > 1 rescan for the storage of preparation step (see MRS. Advanced settings)

  -data store not picked up by discount vmfs (SRM a timeout when refreshing VMFS which can be increased)

  -datastore not zoned properly on all hosts, look to see if some hosts have access and not others... which is usually a sign of your problem is one of the first two points and it is easy to see in the SRM newspapers so you should hire vmware support.

• Configuration of database running on the server with 256 cpu

  Hi all
  
  We have a rac 11.2.0.2 on Solaris 10 installation.
  The servers are 2 and a short configuration is:

  There are a lot of settings Oracle automatically design based on the number of CPUs.
  In my case, this number is too high.
  
  For example, normally db_cache_size = 4 MB * cpu, in this case the result is 1 G of db_cache_size.
  
  The plan is to create several databases on this car, so the question is:
  
  Is there a way to design or to tell oracle a different number of cpu?
  and in general...
  You have some tips on how it is possible to configure a machine so powerful that runs a large number of instances?
  
  
  Thanks in advance
  
  Published by: Spugna on May 7, 2012 03:01

  Hi Spugna,

  Of course, as long as you use Oracle 11 g you can use Instance Caging to limit each database, the CPU usage. Although it is no longer applicable to the single server database or a CCR node I see no reason why not to use with RAC. Look here for more information:
  http://docs.Oracle.com/CD/E14072_01/server.112/e10595/dbrm007.htm

  You could also consider the consolidation of these different in a large database of databases if it is possible and there is no dependence application?

  Kind regards

• Configure two MS for two databases on a single host, EM for first DB cannot open

  Hi all
  
  My 10 g database version 2.
  
  In the beginning, I created a database called "ORCL" and configured the EM to her, not manually of course. and it was working fine.
  Then, later, I found that I need to install a second database called "ORCLDW", and since I have used DBCA to create, EM is configured automatically as well.
  
  EM for ORCL is: http://phoenixbai:1158 / em
  EM for ORCLDW is: http://phoenixbai:5500 / em
  
  the problem is that the EM for ORCLDW works perfectly fine, even if I can't open the EM for ORCL.
  
  When I use 'emctl start dbconsole', it works for a very long time, but still, he tells 'EM for ORCL is started successfully.
  However, when I try to open the URL: http://phoenixbai:1158 / em
  Once again, it lasts very very long and doesn't have to open it.
  
  Then, someone at - it never met the similar situtaiton?
  someone has an idea of what could be the reason? and how to check and fix it?
  
  I thank you very much in advance and wish you all a great weekend!

  the default behavior for OEM is that it supports a single database for each host
  If you need to support multiple DBs, use Grid Control.

  BTW - OEM is NOT necessary to run or support of Oracle's RDBMS

• Cannot run FPGA by host

  My program has normally run this afternoon, but after I saved the new file (seems no change), I can no longer see the wave in the wave chart more at the launch of the vi of the host.  Only when I keep the FPGA vi running can the wave be displayed on the chart.  I don't understand what happened.  I used Run like the invode method but I can't browse FPGA vi host more.  Any help will be much appreciated.  I've also attached the FPGA and host vi, which is barely changed from the examples.

  You have no need to run it invoke the method as your open FPGA VI reference is currently configured to automatically run the VI. I recommend you either remove the invoke method or right-click of your FPGA VI reference open and change its options so that it is not automatically run.

  The way you transfer your data between your FPGA and host VI could be the problem. Currently on your FPGA VI, you have a waveform chart and a function of bundle. As a general rule, you don't want no graphics on an FPGA VI front, since it is as just the low-level code do your FPGA-level tasks. Display you your data when you pass it to your host. In addition, there is no reason to combine a single item of data in a cluster, you can just do an indicator I16.

  In addition, I do not understand the system calendar, maybe I'm just confused here. Your front panel for loop rate default configures the FPGA VI to enter a new sample of AI every 100uS. Which means the FPGA will be claiming a break 10,000 times per second. You have your host VI set up to wait for a break before the reading of the indicator, but the host is configured to run every 10ms, or 100 times per second. Basically you have your FPGA and your host VI running at different rates orders of magnitude, but try to synchronize the bed with an interruption.

  You can run the FPGA and host screw at different rates with success using a FIFO of DMA or a queue, between them. Ensure your FPGA VI is grabbing samples very fast and packing in a queue, one both for the host VI to grab a chunk of at a slower interval. There is a great document on how to do it here: http://zone.ni.com/devzone/cda/tut/p/id/4534

• Setup.pl running on the host with no existing data storage

  I have a new environment, I'll put up: Dell Vmware 5.0 guest (s) and a 10 Gb Equallogic SAN PS61xx

  I am the great Dell documentation and want to run setup.pl to configure my Vmware Vswitches, then install the DellMultipathing (MEM)

  I installed Vsphere CLI on my workstation to mgmt and you attempt to run this command:

  Setup.pl - installation - server = 172.19.0.203 - bundle = dell-eql-mem-esx5 - 1.2.0.365964.zip

  This operation fails because there is no data presented to the host still store

  I'm in the chicken and egg scenario, I need available storage to be able to connect to the storage!

  How to do this? running off a VMA device would be different? (I think VMA runnign out of my workstation management using VMware Workstation)

  Thank you

  Looks like you have currently not iSCSI installation program.  The option - install option assumes iSCSI is already running.   You simply install the software.

  In the user guide starting on page 7 is the use of setup.pl to configure iSCSI and then install MEM in addition to this.

  Setup.pl - configure - bestpractices - server = hostname [-username = username]

  [- password = password] - NIC = NIC1, NIC2,... - ips = IP1, IP2,...
