Installing Patch Packages and Configuring Parameters

Installing Patch Packages and Configuring Parameters

Installing Patch Packages

  1. Configure a yum source.

    1. Mount the image file using the KVM. (You can also upload the image file to the server using xftp.)

    2. Run the mkdir -p /mnt/cdrom command to create the cdrom directory in /mnt for mounting the ISO file.
      [root@hw00001 ~]# mkdir -p /mnt/cdrom
    3. Run the mount /dev/sr0 /mnt/cdrom/ command to mount the CD-ROM drive to the /mnt/cdrom directory.
      The CD-ROM drive directory sr0 is used in this example. Change it as required.
      [root@hw00001 ~]# mount /dev/sr0 /mnt/cdrom/
      mount: block device /dev/sr0 is write-protected, mounting read-only
    4. Run the vi /etc/yum.repos.d/rhel.repo command to open rhel.repo file and configure the yum source.
      [root@hw00001 yum.repos.d]# vi /etc/yum.repos.d/rhel.repo
      name=Red Hat Enterprise Linux $releasever - $basearch - Source

    • libstdc++-4.8.5-4.el7.x86_64
    • libuuid-2.23.2-26.el7.x86_64
    • uuidd-2.23.2-26.el7.x86_64

  1. Run the yum install -y tuned tuned-utils libtool-ltdl ntp command to install the patch packages.

    yum install -y tuned tuned-utils libtool-ltdl ntp

  2. Use xftp to upload the patch packages to the /home directory.

    1. Obtain the xftp installation package and install it.
    2. Use Xshell to log in to the IP address of the server OS management port.
    3. Click the file transfer icon, as shown in the following figure.

    4. Double-click the upgrade file to be uploaded in the left pane. The file is uploaded and displayed in the root directory in the right pane.

      This procedure uses an image file as an example to show the file transfer process. If you want to upload a file to the /home directory, select the /home directory in the right pane.

  3. Run the cd /home command and then the yum localinstall -y *.rpm command to install the downloaded patch packages.

    cd /home
    yum localinstall -y *.rpm

Setting SAP HANA Parameters

  1. Run the following command to set tuned to profile sap.

    # yum install tuned-profiles-sap-hana
    # systemctl start tuned
    # systemctl enable tuned
    # tuned-adm profile sap-hana

  1. Run the vi /etc/sysctl.d/sap_hana.conf command to open the sap_hana.conf file. Add kernel.numa_balancing = 0 to the file to disable auto-numa balancing. Then run the sysctl -p /etc/sysctl.d/sap_hana.conf command for the configuration to take effect.

    [root@hw00001 ~]#vi /etc/sysctl.d/sap_hana.conf
    kernel.numa_balancing = 0
    [root@hw00001 ~]#sysctl -p /etc/sysctl.d/sap_hana.conf

  1. Run the systemctl stop numad and systemctl disable numad commands to disable numad.

    [root@hw00001 ~]#systemctl stop numad
    [root@hw00001 ~]#systemctl disable numad

  1. Run the echo never > /sys/kernel/mm/transparent_hugepage/enabled command to disable transparent huge page.

    [root@hw00001 ~]#echo never > /sys/kernel/mm/transparent_hugepage/enabled

  1. Run the vi /etc/default/grub command to open the grub file and insert the following content to the GRUB_CMDLINE_LINUX line.

    [root@hw00001 ~]# vi /etc/default/grub
    GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
    GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet efi=old_map transparent_hugepage=never intel_idle.max_cstate=1 processor.max_cstate=1 nowatchdog nosoftlockup rcupdate.rcu_cpu_stall_timeout=600 rcupdate.rcu_cpu_stall_suppress=1"

  1. Run the grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg command to generate a new grub file.

    [root@hw00001 ~]#grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg

  1. Run the vi /etc/sysconfig/selinux command and change SELINUX=enforcing to SELINUX=disabled to disable SELINUX.

    [root@hw00001 ~]# vi /etc/sysconfig/selinux
    # This file controls the state of SELinux on the system.
    # SELINUX= can take one of these three values:
    #     enforcing - SELinux security policy is enforced.
    #     permissive - SELinux prints warnings instead of enforcing.
    #     disabled - No SELinux policy is loaded.
    # SELINUXTYPE= can take one of three two values:
    #     targeted - Targeted processes are protected,
    #     minimum - Modification of targeted policy. Only selected processes are protected.
    #     mls - Multi Level Security protection.

  1. Run the vi /etc/systemd/logind.conf command to edit the file and insert RemoveIPC=no.

    [root@hw00001 ~]#vi /etc/systemd/logind.conf

  2. Run the systemctl restart systemd-logind.service command for the configuration to take effect.

    [root@hw00001 ~]#systemctl restart systemd-logind.service

  3. Run the following commands to generate SAP HANA links:

    ln -s /usr/lib64/ /usr/lib64/
    ln -s /usr/lib64/ /usr/lib64/
    ln -s /usr/lib64/ /usr/lib64/
    ln -s /usr/lib64/ /usr/lib64/
    ln -s /usr/lib64/ /usr/lib64/
    ln -s /usr/lib64/ /usr/lib64/

  4. Run the vim /etc/systemd/system.conf command to open the system.conf file and change the file process waiting time to 900 seconds. Then restart the server for the configuration to take effect.

  5. Check that the systemd version is systemd-219-19.el7_2.4 or later.
  6. If the following error information is displayed when the database is started, comment out Defaults requiretty in the /etc/sudoers file.

    "/etc/sudoers mismatch for required permissions of Storage Connector" when using hdb_ha.fcClientLVM"

  7. If the error message "ERROR: object '/opt/rh/SAP/lib64/' from LD_PRELOAD cannot be preloaded: ignored" is displayed during SAP HANA 1 installation, ignore this message. If you want to clear this message, perform the following steps:

    1. In the home directory of the database user, delete the following line from the hdbenv.csh file:
      setenv LD_PRELOAD /opt/rh/SAP/lib64/

  8. If the error message Cannot access required library '/opt/rh/SAP/lib64/': No such file or directory is displayed during the installation of SAP HANA 2, run the yum install compat-sap-c++-5 command to install the compat-sap-c++-5 software package with the latest version of compat-sap-c++-5-5.3.1-10.

    [root@hw00001 ~]# yum install compat-sap-c++-5

    # Defaults requiretty

  10. Add fs.aio-max-nr=196608 to the sysctl.con file and run :wq to save the modification and exit.

    [root@hw00001 ~]vim /etc/sysctl.conf
