1. Introduction This white paper provides complementary information for how to configure HP OpenView Storage Data Protector in HP-UX Oracle9i Real Application Clusters (RAC) for Zero Downtime Backup (ZDB) and Instant Recovery (IR) in HP StorageWorks Disk Array XP environments. It describes essential steps necessary for the installation and configuration in this type of an environment. The white paper starts with an overview about the architecture of the example environment, which is used throughout this paper. NOTE: The white paper describes only the HP-UX Oracle9i Real Application Clusters together with Zero Downtime Backup and Instant Recovery in HP StorageWorks Disk Array XP environments. The necessary Oracle Proxy Copy feature is only used in Data Protector ZDB environments. Non-ZDB HP-UX RAC environments are configured as RMAN Oracle integrations, which are not focus of this document.

2. Overview of Oracle9i RAC Example Environment The following chapter will explain the environment setup. It will explain the different hard- and software components used for this integration. It is based on the HP MC/ServiceGuard Extension for RAC (formerly called MC/ServiceGuard OPS Edition) which allows multiple servers to be configured as a highly available enterprise cluster that supports Oracle9i Real Application Clusters. In the example environment, all connections to the database are through the primary node called “uranos“ with local database instance “RAC21“. The secondary node, called “thor” with local database instance “RAC22“, could also be configured. NOTE: The network service “RAC2” is neither a database instance nor can it be configured for backups. This is due to the RAC load-balancing feature, which would start backups on any node. Data Protector configured tape devices in RAC environments are host-based and do not swap over. The reading of the database data on one node and saving to tape on another node would result in a network backup.

Figure 1 – High-Level View of Oracle9i RAC Example

The Data Protector server “dpuxcell” is responsible for backing up the split-mirror data from disk array volume “S-VOL” to tape. The archived log files, which are locally written by each database server instance, are backed up from MC/ServiceGuard NFS-shared archived log destinations. The Oracle recovery catalog database instance “OEMCAT” must not be installed on RAC servers. In this setup, the recovery catalog database is installed on server “wotan”.

_____________________________________________________________________

3. Installing Data Protector Agents on RAC Cluster Nodes To back up a RAC Cluster, Data Protector integration software has to be installed on the servers in the RAC environment. The HP StorageWorks XP Agent has be installed on:

• RAC server “uranos” with database instance RAC21 • RAC server “thor” with database instance RAC22 • Backup server “dpuxcell” with access to split-mirror S-Vol disks and tape drives

The Oracle8 Integration Agent has been installed on:

• RAC server “uranos” with database instance RAC21 • RAC server “thor” with database instance RAC22 • RMAN catalog server “wotan” with recovery catalog database instance

OEMCAT

NOTE: On RAC servers “uranos” and “thor” the Data Protector variable “SSEA_IR_VGCHANGE_A” in file “/opt/omni/.omnirc” must be modified for the shared raw device environment:

SSEA_IR_VGCHANGE_A=vgchange -a s For further information on installation procedures, please refer to:

• HP OpenView Storage Data Protector HP Storage Works Disk Array XP Integration Guide

• HP OpenView Storage Data Protector Installation and Licensing Guide

_____________________________________________________________________

4. Preparing the HP Storage Works Disk Array XP Environment All RAC servers and the single backup server should be connected to the same HP StorageWorks Disk Array XP. The primary LDEVs (P-Vols) should be connected to the RAC servers and should have paired disks assigned. The mirrored LDEVs (S-Vols) should be connected to the backup server. For further information on HP StorageWorks Disk Array XP configuration procedures, please refer to:

5. Preparing the HP-UX and Oracle9i RAC Environment This chapter gives complimentary information to the following documentation:


• Oracle9i Real Application Clusters Administration Release 2 (9.2) • Oracle9i Real Application Clusters (RAC) on HP-UX – available at the

HP/Oracle Cooperative Technology Center (http://otn.oracle.com/products/oracle9i/htdocs/9iRAChp.html)

5.1. Requirements

Please check that the following requirements are met before installing and configuring the Oracle9i RAC environment:

• System requirements • HP-UX operating system patches • Kernel parameters • Asynchronous I/O

5.2. Raw Logical Volumes

Data Protector makes use of the Oracle Proxy Copy feature, which creates a list of all necessary files for backups. This list of files is actually a list of symbolic links, which point to the database raw logical volumes. After the raw logical volume creation it is necessary to create symbolic links for each raw file on all RAC nodes:

# cd /oracle/RAC/ (directory where you want to have the links) # ln -s /dev/vg_rac/rac_raw_system_400 rac2_system # ln -s /dev/vg_rac/rac_raw_user_120 rac2_user etc.

5.3. Oracle Archived Log Files

Saving archived redo logs in Oracle Real Application Clusters environments causes special problems and must be carefully considered. In this example environment, the archived log files cannot be on a shared disk because all shared disks are raw devices. Therefore, file systems have to be created on each node. This setup results in local written archived log files, which must be saved from each local database instance. It is possible to save archived log files by:

• Backing up from each node with two backup jobs. Two single backup specification are used.

• Backing up from each node with one backup job and SQL-remote-connect statements: ”allocate channel c1 type sbt connect ...@node1;” ”allocate channel c2 type sbt connect ...@node2;”

• Saving NFS-cross-mounted file systems with one backup job. Uniquely named local directories are NFS-soft-mounted to all other nodes.

NOTE: All above described solutions are not recommended due to the low reliability. The major disadvantages are:

• In a media recovery scenario, you must configure the node performing recovery for remote access so it can read the archived log files in the archiving directories on the other nodes.

• This local backup has a single point of failure. If one node fails after the most recent backup, then the archived logs on this node that were generated after the backup are lost. If you are in a recovery situation and do not have all available logs, then you are forced to perform an incomplete recovery up to the first missing archived log sequence number.

The best solution is to use NFS implemented for high availability. This solution makes use of the exported NFS directory stored on the shared disks of the cluster. One node is the primary node that is used to give access to the archived log files. If this node fails, a failover process alters the access path to a backup node that also has access to the shared disks.


11


_____________________________________________________________________

In the example environment, the archived log file system are mounted from the virtual hostname “nfspkg.sss.bbn.hp.com”:

uranos # bdf Filesystem kbytes used avail %used Mounted on nfspkg1.sss.bbn.hp.com:/export/oracle/RAC2/admin/arch_1 4194304 3439896 707288 83%

/oracle/RAC2/admin/arch_2 For further information on archived log file backups in RAC environments, please refer to the following documentation:

• Oracle Recovery Manager User’s Guide Release 2 (9.2) • Oracle9i Real Application Clusters Administration Release 2 (9.2)

5.4. Oracle RMAN Snapshot Control File

In Real Application Clusters, identical copies of the snapshot control file have to exist on every node that performs backups. Therefore, make sure that the same destination directory for a snapshot control file exists on all nodes used for backups. In the example environment, the unique snapshot control file directory “/oracle/9.2.0/dbs/scf” is mounted on node “thor” from node “uranos”, which executes ZDB database backups:

thor # bdf Filesystem kbytes used avail %used Mounted on uranos.sss.bbn.hp.com:/oracle/9.2.0/dbs/scf 4194304 3439896 707288 83%

/oracle/9.2.0/dbs/scf

NOTE: The snapshot controlfile location must be configured after the database creation with the RMAN “CONFIGURE SNAPSHOT CONTROLFILE NAME” command.

6. Oracle9i RAC Integration and Configuration

The following steps are executed after the Oracle9i software installation and database creation. This chapter gives complimentary information to the following documentation:

• HP OpenView Storage Data Protector UNIX Integration Guide • HP OpenView Storage Data Protector HP Storage Works Disk Array XP

Integration Guide

6.1. Configuring the Oracle Server

The following example describes the integration with the CLI “util_oracle8.exe”:

uranos:oracle:oracle/9.2.0 /opt/omni/lbin/util_oracle8.exe \ -CONFIG_SMB RAC21 /oracle/9.2.0 /oracle/9.2.0/dbs/initRAC21.ora \ /dev/vg_rac2/rDP_controlfile <user>/<password>@RAC21 \ <user>/<password>@OEMCAT

Note: Some Oracle9i RAC installations are configured with binary server parameter files, which are located on raw logical volumes and shared by all RAC instances. This results in non-existing init.ora files, which are essential for the Data Protector Oracle integration. In this case, the binary server parameter file must be converted in a text-initialization parameter file (init.ora) with the SQL-command:

“CREATE PFILE=‘/oracle/9.2.0/dbs/initRAC21.ora’ from SPFILE ; ”

6.2. Creating Backup Specifications

Backup specifications must be separately created for database and archived log file backups. Note: Archived log files cannot be saved together with the ZDB feature and must be saved with a separate backup specification. It is recommended to create an additional backup specification for another RAC node, which could be used in case of a single node failure.


16

The following example describes the backup from RAC instance “RAC21” to Mirror Unit (MU) numbers “0-1”. Example from a GUI created backup specification “RAC21-ZDB-TAPE” for backup to disk and tape:
