• ASM vs RAID for RAC 11 GR 2 environment

  Hello!
  We plan to install 11 GR 2 CARS with two-node Cluster on LINUX in our environment.
  Operating system: OEL 5.4
  In our material, we got two dell servers with 16 GB of RAM on each side more on SAN we have only 8 (173 GB) disk left for RAC Cluster configuration. I create the database (LIVE/UAT) on this Cluster Setup. Currently our Production DB dimensions are 6 GB and I assumed that for 5 years, that he's not going beyond 100 GB coming and I keep size UAT 15 GB difficulty without modification. So, how do get you the best performance from ASM using my all resources.
  
  My question:
  (1) who is the best solution for the ASM and RAID in our storage environment?
  (2) disc how do I create a group for the two databases (UAT/LIVE)?
  (3) records how much should I allocate in each group of disks with RAID Option or if all this suggests for LUNS, how to create LUNS on the disk I got?
  (4) I know oracle recommends two DATA DISK group & FRA is there any suggestion of CRS, REDO and TEMP FILE?
  Thank you for your Assintance.
  
  Nadège.

  My first question was: which RAID Option (0,1,5,0+1) I choose with ASM?

  Well, it does not matter for the DSO. At least in your configuration with 8 disks.
  RAID0is not an option - forget about it. RAID1 (or combined with more than two discs and a RAID0 superimposed making it a RAID 1 + 0) could be an option for the writing intensive databases. RAID5 is more for intensive reading due the RAID5 write hole but offers a capacity of 'more' at the expense of slower writing speed.

  I have recommended to the stick with RAID1 (mirroring two disks) and exporting to ASM rather than create a big RAID1 + 0 on all of your discs and exporting as a big Chuck of ASM storage for the management of. If you want to add storage lateron your perfect according to the recommendations of the Oracles have LUNS of equal size in ASM with two mirrored drives. If you create it large RAID 1 + 0 and lateron add two drives you have a 600 GB size logic unit number and a 170 GB size... it's a big shift.

  But if I create TWO group of disk then, is it advisable to provide two data bases (UAT/LIVE). ?

  Normally, there is a separation between UAT and P on the storage and the server level. In your case, it might be 'ok' to do everything in the same disk group. It depends especially of what database puts the load on the disk subsystem.

• Could some expert if you please help me to configure Oracle Gateway for DRDA.

  Hi Experts,
  
  Could you please give me the steps or delete the document to install and configure the oracle for DRDA gateway. I need to put up with the db2 database.
  
  Platform: AIX
  Database version: 11.2.0.3
  
  I'd really appreciate it if experts will extend their assistance in this regard.
  
  Thank you

  Hello
  To answer your questions-

  1. I already have a listener running on my oracle database, which is under home(/u01/app/asm/product/11.2.0.3/grid/network/admin) GI.

  -You must create a new listening port for the gateway in the directory $GATEWAY_ORACLE_HOME/network/admin
  -for your configuration, this looks like it should be-
  /U01/app/Oracle/product/11.2.0.3/dt02/network/admin
  -start the receiver of the gateway by using the executable in /u01/app/oracle/product/11.2.0.3/dt02/bin lsnrctl

  2. I read the Document Oracle, which has been mentioned by the experts above, however got little confused where to run scripts to create the Tables and the data dictionary support Beta project views...
  -you need run the scripts in the database non-Oracle to which you are connecting.
  So, if it's DB2 on zOS, then run "zos" scripts DB2 itself, if it is DB2 on Linux, Unix or Windows, then run "luw" scripts in DB2.

  3. is there anything that either I should suggest for DB2 guys to go he ends to make it effective.
  -Make sure that they granted the necessary authorizations for such users as specified in the documentation, in particular the user that links the gateway packages.

  Kind regards
  Mike

• Please help to configure the router for internet connection 871W!

  Hello world!

  I just started styding for CCNA, so I'm totally new to Cisco stuff. Recently bought a router 871W and spent two days in a row trying to configure internet connection with no luck! I use the port console for the configs and SDM/CCP. Would be greateful if someone could tell me how to do simple configs of internet connection. I googled everything but it's still confusing. I can't assing all-IP ports FA 0-3. I used instead of the VLAN. But all tutorials use FA0 and when I try to assign an IP address to FA0 it gives me some L2 cannot be assigned or something... :/ And I am also confused at what address IP use for WAN.

  I connected the cable between the Modem and the LAN of the PC port and copied some IP addresses which I think I have to use to configure the router for internet connection. And here they are:

  ISP IP: 76.114.54.255

  SUBNET: 255.255.248.0

  GATEWAY: 76.114.48.1

  DHCP: 69.252.97.4

  DNS: 75.75.75.75

  75.75.76.76

  If you can, please help! Thank you!

  Hi david,

  Looks like your 871w can not get a dynamic IP address: % unknown DHCP problem... No possible allocation

  you could ask your ISP to perform a reset/clear MAC add and try again?

  also, kindly post lastest "show run".

  Edit: just to see you've updated your screenshot. could you add command under 4

  Master Page Items question: I use master pages for a 60 page document and just found out that some of my master page items are multiplying! There are some boundaries on the pages, and some of them are constantly a quantity apparently without end on top of the other. For example, I replace to change the color of the border and notice a black there's below him so I deleted the extra and there is another and another and another... EEK. I can easily hide them, BUT I fear they will lead to complications in the case of pre-press printing. What is the cause? What can I do to prevent it? How can I get rid of the stack-up?

  It's always haapening, if you substitute any element on the page and later master you reapply the same or another master. I would NEVER say to replace any itme master page in the page. Instead create another master based on the first, make the substitutions and apply this master. Substitutions on the pages should be avoided in all cases, not only for the problem you described above, other issues of accessibility will also come into play.

• Best configuration of switch for 4 natachasery - 5 ESXi

  So, I need to tell my boys to network how I want the configuration of ports (Cisco switches) for 4 natachasery connection to my HP DL 360. I need the vSwitch VM access to 3 different VLAN. I'm NOT going to use vMotion for this.

  I guess, I see 2 possibilities and does not entirely undesrstand pros / cons...

  First of all, I thought I would split the enet to 2 separate switches cables, but I was told that if I chose that this channel of ports 1 route would be active and 2nd would be Eve. Basically can not paste all 4 cards and divide them. This could reduce the bandwidth, but give me a redundancy using 2 physical switches.

  Or I can have all 4 enet cables go to the same switch (etherchannel), but if this switch would die I'm dead in the water, AND I think that EtherChannel mode WE (my network guy preferred LACP) should stay and LACP cannot be used. According... http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & docTypeID = DT_KB_1_1 & externalId = 1004048 I think I should also use 'Hash IP' if EtherChannel is used.

  So what is the advantage or disadvantages of each channel? Thank you!

  This article describes the aggregation of ESX/ESXi links:

  • ESX/ESXi host only supports grouping NETWORK adapters on a single physical switch or stacked switches.
  • Aggregation of links is never supported on disparate networks switches.
  • The switch must be set to perform 802.3ad aggregation of links in static mode WE and the virtual switch must have its defined route based on the IP hashload balancing method.  Ensure that participants of the network adapters are connected to the ports configured on the same physical switch.
  • Allowing each route based on the IP hash without 802.3ad aggregation or vice versa disrupts networking, so you must make the changes to the virtual switch first. In this way, the service console is not available, but the physical switch management interface is, so you can activate the aggregation on the affected ports to restore network.
  • For more information on ESX networking concepts, see the VMware Virtual Networking Concepts.
  • For more information on configuring a VLAN for NIC teaming, see Configuration of VLAN Virtual Switch, switch physical and virtual machines (1003806).
  • To set up the consolidation of NETWORK cards on ESX and a physical switch, see example configuration of EtherChannel / link aggregation with ESX/ESXi and Cisco/HP switches (1004048).
  • The only option for switch vSwitch or vDistributed that can be used with balancing EtherChannel is HASH IP.
  • Do not use tag with IP HASH load balancing.
  • Do not uplinks configure standby or not well obliterated with IP HASH load balancing.
  • VMware takes support only a single Etherchannel by vSwitch or distributed vNetwork (vDS).

  In my case with no vMotion and just management and 3 VLAN all about 1 vSwitch I should put them all to active?

  Yes, they should all be active, there is really no need passive adapters (that I'm aware of your configuration).

  On your physical switches, you don't need to do anything more than what allows a VLAN correct, i.e.: should all etherchannel or a similar montage. Side vSwitch, you must use the default 'Port ID' nic teaming strategy.

• Upgradation OS for RAC

  Hi guys... How is everything...
  
  I have the node CCR on Windows2003R2 Itaniam. I need to know is there any procedure for upgradation OS for RAC... I mean I'm going to the bottom of the Cluster & when the OS database places a gradation.

  Hello

  you need not stop the entire base.
  Upgrades of the OS can be in upgradeable mode (so one node after another), you must stop the instance and the clusterstack on the node, you perform the upgrade.

  Policies to support Oracle to launch of the CARS with different versions of an operating system within a period of 24 hours.
  In other words: after completing the upgrade of the first node you have 24 hours to what your other nodes must be at the same level of the new OS.

  Concerning
