• Paths multiple problem with PowerVault MD3200i + Oracle Enterprise Linux (5,7)

  Hello

  I'm trying to configure MPIO on a host (running Oracle Enterprise Linux Server 5.7) connected to an Powervault MD3200i. I have a few unexpected problems with/dev/dm-0 missing after reboot.

  I configured 3 virtual disks (RAID 1) with MPIO. 3 devices have been created (/ dev/dm-0, / dev/dm-1 and/dev/dm-2).  If I mount them manually, they work very well, so I've added to the fstab. After a reboot, I checked that/dev/dm-1 and/dev/dm-2 have been automatically but is not/dev/dm-0. In fact, the/dev/dm-0 has disappeared from the directory of the device (!)

  If I rinse 'multipath f' and ' multipath - v2 "the device gets recreated, but disappears on the"
  next reboot again. How can I resolve this behavior? Can anyone help?

  Thanks in advance.

  See you soon

  I thought about it... the problem is that I had the wrong specified dev in fstab.

  Should I use the devices in/dev/map /... it worked immediately.

• VMware p2v oracle enterprise linux

  Hi people,

  I need to perform a p2v of oracle enterprise Linux server.

  Can someone please tell me the correct procedure (if no document is available, that would be great ), thanks for the pointers.

  This was better than I expected, I downloaded converter 5.5.1 and it went smoothly, no reconfiguration needed, it installs GRUB, patch mount point entries in fstab and re-create the virtual disk original (all automatically).

  Bravo from VMWare.

• Can I use file of udev rules for RAC on Oracle Enterprise Linux 6 11.2.0.3?

  Version of the grid: 11.2.0.3
  Platfomrm: The last Oracle Enterprise Linux 6 (Unbreakable Enterprise Kernel)
  
  
  Yes guys Oracle sales have convinced our Manager to go OEL of AIX.
  We plan to install RAC on Oracle Enterprise Linux 6 (UEK) 11.2.0.3.
  
  I read this thread on the asmlib and udev rules file.
  List of rules for CAR 10.2 udev
  
  As a benefit to ASMLib, periera Levi said (quotes)
  '+ A good async IO interface to the database, all the I/o interface is based on a model of performance + ASYNC'
  
  Oracle is not out for 6 OEL or RHEL 6 AsmLib. I think that they will not release asmlib more.
  
  So, we will use only the udev rules file. Without ASMLib, we will have an ASYNCHRONOUS i/o or other storage related issues?
  
  Someone at - it successfully installed 11.2.0.3 RAC OEL 6 with udev rules file?

  I use +/etc/udev/rules.d/40-multipath.rules+ udev file to configure the permissions of device of multiple devices on path to e/s for use by o/s user grid.

  It is as follows:

  # modded for setting mpath device permissions
  
  SUBSYSTEM!="block", GOTO="end_mpath"
  
  KERNEL!="dm-[0-9]*", GOTO="end_mpath"
  
  PROGRAM!="/sbin/mpath_wait %M %m", GOTO="end_mpath"
  
  ACTION=="add", RUN+="/sbin/dmsetup ls --target multipath --exec '/sbin/kpartx -a -p p' -j %M -m %m"
  
  # goto labels added
  PROGRAM=="/sbin/dmsetup ls --target multipath --exec /bin/basename -j %M -m %m", RESULT=="?*", NAME="%k", SYMLINK="mpath/%c", GOTO="check_cluster_devs"
  PROGRAM!="/bin/bash -c '/sbin/dmsetup info -c --noheadings -j %M -m %m | /bin/grep -q .*:.*:.*:.*:.*:.*:.*:part[0-9]*-mpath-'", GOTO="check_cluster_devs"
  PROGRAM=="/sbin/dmsetup ls --target linear --exec /bin/basename -j %M -m %m", NAME="%k", RESULT=="?*", SYMLINK="mpath/%c", GOTO="check_cluster_devs"
  
  GOTO="end_mpath"
  
  # set device permissions for Grid Infrastructure
  LABEL="check_cluster_devs"
  RESULT=="*", GROUP="oinstall", MODE="660"
  RESULT=="*", OWNER="grid", GROUP="oinstall", MODE="660"
  OPTIONS="last_rule"
  
  LABEL="end_mpath"
  
  # eof
  

  I understand that it is no longer necessary that can be configured in +/etc/multipath.conf+ as follows:

  ..
  multipaths {
      multipath {
          wwid  SSCST_BIOscst1_sdb_757d30d0
          alias scst1_sdb
          mode 0660
          uid oinstall
          gid grid
        }
  .. etc.
  }
  

  However, has never work properly myself--must do something wrong that I saw a few sources Internet showing it works.

  As far as I KNOW, it is also with OL6 (as it is with OL5 and earlier versions), not a question of AsmLib or udev/MPIO. Udev is a Mapper devices used by the kernel. The decision is whether to add another layer called AsmLib. Personally, I have yet to see any convincing evidence that why should I increase the complexity of the kernel driver stack, adding AsmLib. We also had a few serious incompatibility with AsmLib issues in the past (where he with, caused compatible I/O corruption at the logical level).

  If you look at the clusters in the www.top500.org list, many of them have shared storage accessible via udev/multichemin Pentabytes and nothing else. MPIO has its roots as a driver of kernel for these groups. One of the reasons why we stopped years ago to use EMC Powerpath for our CARS that are wired to EMC San to shared storage.

• Oracle 10g on Oracle Enterprise Linux 6 using VMWare

  I am trying to install Oracle 10 g on a Linux server. The reason is that the system, which I am working 10g and want a test environment on my computer.
  I installed the latest version of Oracle Enterprise Linux 6 on VMWare Player.
  So far so good.
  Now I want to install 10g on the system and have read both Expert Oracle 10 g database Administration and the fast for 10g Release 2 Setup Guide (10.2) for Linux x 86
  I seems to be now stuck in the situation to get all loaded packages that are recommended. Some of the packages are not on the cd, so I'm starting to wonder if it is a valid version for installation.
  Because the version is releast Red Hat Enterprise Linux Server 6.0, I had that with
  # cat/etc/redhat-release
  
  So 10g is not supported on this version?
  If so do I download the previous version of Linux?
  If so what version and if you can direct me in the sense I would be really happy.

  Currently 6 Linux is not certified to any version of database Oracle.

  Operating system for 10 g 2 (which is what I assume you are using) is listed in the Release Notes - http://download.oracle.com/docs/cd/B19306_01/relnotes.102/b15659/toc.htm#CHDFHIEA

• Application specialist Oracle Enterprise Linux - 1z0-402

  I saw [http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=351] and [http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=144] I think I notice a change.
  
  After having passed 1z0-402 (just now) to get this (Oracle Enterprise Linux application specialist) certification?
  
  
  Or certification is available to those within the Oracle partner network?
  
  
  Page: [http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=146] is not clarified this.
  
  
  Some certifications and existing reviews seem to be spring upward with this logo attached, clarification would be useful.
  
  
  
  I confess that I feel the pass mark on this review associated with 57% is too low to justify the title of the certification associated without the title of devaluation. I wouldn't think of someone who passed this exam with 58% being sent to me as a specialist of Oracle partner Oracle Enterprise Linux network implementation. Probably a pass mark of 65 to 70% would be reasonable, and I would plump for 67%.

  If you took the review 402 previously, you should automatically receive implementation specialist Oracle Enterprise Linux certification. This certification is available for all candidates and not OPN members only. If you do not receive this certificate within 4 to 6 weeks, please contact [email protected] customer service and they will help with the reception of this certificate.

  With regard to the test score. Results of the review reflect the level of difficulty of the examination. More scrutiny is difficult, more passing grade. This is a very simplified explanation for everything that will determine a test score. There are a lot of mechanics that go into determining the points of overtaking, but a decisive factor is the level of difficulty of the examination.

• Oracle enterprise linux and oracle 10g?

  Hey;
  
  I am fairly new to try to download oracle and get installed on a linux machine. I made a few attempts on linux fedora core 10 and home edition of windows vista that does not go very far. Since I just passed my exams for ocp via a boot camp (yay for me!), I'm hoping to get a couple of linux boxes operational so that down the concepts by the practice.
  
  From what I read, it seems that I can download enterprise linux, put it on a system and then download oracle 10g and install this w/little or no difficulty (at least not expected...)
  
  Am I reading that right or did I miss something? Any info greatly apprecaited.

  Hello

  You can download enterprise linux and 10g and go there. Pre-packaged for the components required to install the oracle Enterprise linux software, here is a link for further reference see cross-platform compatibility.

  Everything you did for RHEL5.2 will work perfectly in OEL5.2

  You raise a very good point: the unfortunate fact is that there is * nothing * to all to OEL a house "better" or "easier" for that plain old RHEL Oracle databases. There is no core set environment variable user parameters or pre configured, for example, it would be just for an Oracle straight out of the box installation: you must always you fix all exactly as if it were of RHEL.

  This is normal: OEL was and is intended to be binary compatible with RHEL and therefore no settings of Oracle or parameters that are not in RHEL can be included in the OEL.

  So yes, if it's complicated on RHEL, it is exactly as complicated as on OEL.

  (I'm biased though: If you use my script to doris, you will find that you can install Oracle on virtually any Linux distribution as easily as any other.) See http://dizwell.com/2008/05/01/doris-redux, and if you want to watch a video of how to do to use the script: http://dizwell.com/2008/09/29/proving-a-point/)

• Process memory usage 99% Oracle

  Hello

  I'm working on a linux server:

  Red Hat Enterprise Linux Server version 5.7 (Tikanga) Beta.

  This server contains multiple instances use the same Oracle home all:

  Oracle Database 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production

  A few days ago, I have add 15 GB of memory for a total of 70 GB of memory and 40 GB of swap.

  But the use of memory still and always 99% when I use the command "top":

  CPU: 0.3%us, 0.3%sy, 0.0%ni, 99.3%id, 0.2%wa, 0.0%hi, 0.0%si, 0.0%st

  MEM: 70947372 k total, 70599172 k used, 348200 k free, 559640 k buffers

  Swap: 41945704 k total, 191308 k used, 41054396 k free, 62598884 k cached

  And when I check the process using more memory I got this list:

  PID USER PR NOR VIRT RES SHR S % CPU % MEM TIME + COMMAND

  21948 oracle 15 0 oracle 8.9 0.0 0:52.53 9483 m 6.0 g 6.0 g S

  21968 oracle 15 0 oracle 2.3 4.5 2:57.26 9493 m 3.0 g 3.0 g S

  The process of PID 21948 (using 6 GB of memory) is:

  PID % CPU % MEM VSZ RSS TTY STAT START TIME COMMAND USE

  Oracle 21948 8.9 0.0 9710892 6336604?     SS 2015 0:52 ora_mman_ORACLE_SID

  
  

  and the second on the list (21952 PID) is:

  PID % CPU % MEM VSZ RSS TTY STAT START TIME COMMAND USE

  Oracle 21952 8.3 0.0 9740328 5909300?     SS 2015 08:55 ora_dbw0_ ORACLE_SID

  These 2 processes are on the same ORACLE_SID.

  My question to is this normal? And if not, how can I reduce the use of memory on this ORACLE_SID?

  I thank in advance for your help

  Concerning

  BTW: I'm sorry for my bad English.

  Hello

  CPU: 0.3%us, 0.3%sy, 0.0%ni, 99.3%id, 0.2%wa, 0.0%hi, 0.0%si, 0.0%st

  MEM: 70947372 k total, 70599172 k used, 348200 k free, 559640 k buffers

  Swap: 41945704 k total, 191308 k used, 41054396 k free, 62598884 k set caching

  
  

  From above, you can see only ~ 62 GB on your 70 GB is cached in the OS. You can get the best idea using the free command.

  also your server isn't swapping and it seems almost inactive.

  It is normal that the OS to cache the free memory space and report as used (70599172 used, k ), but it may affect the oracle db performance as well (https://asktom.oracle.com/pls/asktom/f?p=100:11:P11_QUESTION_ID:7931107631402).

  Try this - http://www.pythian.com/news/29703/oracle-instance-memory-usage/ for each of your instances.

  As far as I know, different instances may share only the binary code oracle and using libraries, so you should be able to easily understand the amount of memory of all instances of 12.
