Veritas InfoScale™ 7.4.1 Virtualization Guide - AIX

To enable ODM file access from WPAR with VxFS

1. (Optional.) Create a system WPAR.

   For example:

   # mkwpar -n orawpar

   For other options while creating WPARs, refer to the IBM Redbook for WPAR.

2. Start the system WPAR.
3. Create VxVM volumes and VxFS systems for the databases in the global environment.

   For example:

   /dev/vx/dsk/oradatadg/oradatavol,
   /dev/vx/dsk/oradatadg/oraarcvol,
   /dev/vx/dsk/orabindg/orabinvol

4. Make sure that the mount point directories are created inside the WPAR base directory from the global environment.

   For example:

   # mkdir -p /wpars/orawpar/oracle/oradata
   # mkdir -p /wpars/orawpar/oracle/oraarc
   # mkdir -p /wpars/orawpar/oracle/orabin

   Note:

   While creating the directory, use the complete path of WPAR.

5. Mount the VxVM volumes with VxFS systems on the following mount points.

   For example:

   # mount -V vxfs /dev/vx/dsk/oradatadg/oradatavol\
   /wpars/orawpar/oracle/oradata
   # mount -V vxfs /dev/vx/dsk/oradatadg/oraarcvol\
   /wpars/orawpar/oracle/oraarc
   # mount -V vxfs /dev/vx/dsk/orabindg/orabinvol\
   /wpars/orawpar/oracle/orabin

6. Make sure that the ODM pseudo device /dev/odm is mounted on the /dev/odmdirectory in the global environment.

   For example:

   # mount -V odm /dev/odm /dev/odm

7. Share the /dev/odm directory from the global environment using namefs mount. The mount point dev/odm directory must be created inside the WPAR base directory from the global environment. This step enables ODM file access from WPAR.

   For example:

   # mkdir -p /wpars/orawpar/dev/odm
   # mount -V namefs /dev/odm /wpars/orawpar/dev/odm
   # mount (only related with above commands)

   /dev/odm                         /dev/odm                      vxodm   Jun 09 17:30  smartsync
   /dev/vx/dsk/oradatadg/oradatavol /wpars/orawpar/oracle/oradata vxfs    Jun 10 14:08
   rw,delaylog,suid,ioerror=mwdisable,qio,largefiles
   /dev/vx/dsk/oradatadg/oraarcvol  /wpars/orawpar/oracle/oraarc  vxfs    Jun 10 14:08
   rw,delaylog,suid,ioerror=mwdisable,qio,largefiles
   /dev/vx/dsk/orabindg/orabinvol   /wpars/orawpar/oracle/orabin  vxfs    Jun 10 14:08
   rw,delaylog,suid,ioerror=mwdisable,qio,largefiles
   /dev/odm                         /wpars/orawpar/dev/odm        namefs    Jun 10 14:44  rw

   Note:

   While creating the directory, use the complete path of WPAR.

8. Log on to WPAR.

   For example:

   # clogin orawpar
   # df -kg

   Global - - - - - /proc
   Global 2.00 1.99 1% 70 1% /tmp

   Global 9.00 1.86 80% 39074 8% /oracle/orabin
   Global 0.00 0.00 -1% 6 100% /dev/odm

9. Install and configure Oracle Database server single instance in the system WPAR.

   See the IBM and Oracle documentation for the detailed information on creating system WPAR and installing Oracle Database server single instance in a system WPAR on AIX.

10. Link the ODM libraries for Oracle inside the WPAR.

    For example:

    # ln -sf /opt/VRTSodm/lib/libodm64.so libodm11.so
    # ls -lta |grep -i libodm11.so

    lrwxrwxrwx 1 root system 28 Jun 10 14:51 libodm11.so -> /opt/VRTSodm/lib/libodm64.so
