Requirements for Oracle and Oracle RAC Environments

This topic describes the user privileges that are required for Oracle and Oracle RAC target and source environments.

The Delphix Server requires two users on source and target environments, the OS User and the Database User. When setting up a source or target environment, the HostChecker script confirms that both of these users exist on the target or source environment. HostChecker includes a script, createDelphixOSUser.sh, that allows the system administrator to create an OS User, and prompts for adding primary and secondary group memberships. It also includes another script, createDelphixDBUser.sh, that allows the system administrator to create a Database User. The OS User is necessary for adding an environment, adding a dSource, and provisioning a VDB. The Database User is used for adding a dSource, and taking snapshots of dSources or VDBs.

Environment User Privileges

Source OS User 1. Profile and privileges similar to Oracle User. 2. Write permission to the sqlplus directory, for example $ORACLE_HOME/sqlplus. 3. Write permission to the $ORACLE_HOME/dbs directory. 4. Group Memberships: OSDBA (typically dba) as primary group Oracle Install Group (typically oinstall) as secondary group If ASM is used, asmadmin and asmdba to provision to and from ASM

Source Databas Use the HostChecker bundle script createDelphixDBUser.sh to create a database user for Delphix with necessary Database e User privileges.

Target OS User 1. Write permission to the $ORACLE_HOME/dbs directory. 2. Secondary group membership in the asadmin group for provisioning to an ASM installation. 3. Must have the appropriate permissions on a mount directory for VDBs, for example /mnt/provision. 4. For detection of listeners with non-standard configurations, must have sudo access to pargs on Solaris or ps on Linux, HP-UX, or AIX.

Example (Solaris Source)

Defaults:delphix_os !requiretty delphix_os ALL=NOPASSWD:/bin/pargs

Example (Linux, HP-UX, or AIX Source)

Defaults:delphix_os !requiretty delphix_os ALL=NOPASSWD:/bin/ps

5. sudo privileges mount/umount, mkdir/rmdir. If a provisioning user does not have these permissions, then the mount directory must exist and be writeable by the provisioning user.

Example (All Targets, Standard Listener)

Defaults:delphix_os !requiretty delphix_os ALL=NOPASSWD:/bin/mount, /bin/umount, /bin/mkdir, / bin/rmdir

Example (Solaris Target, Non-standard Listener)

Defaults:delphix_os !requiretty delphix_os ALL=NOPASSWD:/bin/mount, /bin/umount, /bin/mkdir, / bin/rmdir, /bin/pargs

Example (Linux/HP-UX/AIX Target, Non-standard Listener)

Defaults:delphix_os !requiretty delphix_os ALL=NOPASSWD:/bin/mount, /bin/umount, /bin/mkdir, / bin/rmdir, /bin/ps Oracle RAC OS User Source 1. Must exist on all RAC nodes. 2. Must have the same configuration on all nodes (same user id/group). 3. Must have permissions to run crsctl and srvctl.

Example (This shows that the group dba has read/write/execute permission on the database resources)

$ crsctl getperm resource ora.trois.db Name: ora.trois.db owner:ora112:rwx,pgrp:dba:rwx,other::r--

Environment discovery on a single instance or RAC installation relies on the presence of the following files:

/etc/oratab (for single instance discovery only) /etc/oraInst.loc or /var/opt/oracle/oraInst.loc (this file points to $INVENTORY_HOME) $INVENTORY_HOME/ContentsXML/inventory.xml For each Oracle Home, $ORACLE_HOME/inventory/ContentsXML/comps.xml
