Administration II 35-36 Restoring OracleAS Infrastructure to a New Host • • You may need to restore OracleAS Infrastructure to a new host system in case of a host (system) failure To restore OracleAS Infrastructure to a new host, use the following steps: 35-37 Prepare the new host Restore Oracle system files Restore the Infrastructure home directory Restore and recover the Metadata Repository Start the Metadata Repository Start the OracleAS Infrastructure and Application Server Control Copyright © 2004, Oracle All rights reserved Restoring OracleAS Infrastructure to a New Host Prepare the new host: - The first step is to prepare a new host that has identical system configuration as the original host On the new host, make sure that the information such as hostname, virtual hostname, domain name, IP address, hardware platform, operating system release and patch levels is identical to the original host - Make sure the entries such as IP address, hostname, and aliases for the new host in /etc/hosts are identical to the old /etc/hosts file - Check port usage on the new host and ensure that there are no conflicts - On the new host, create an operating system user that is identical to the user who installed OracleAS Infrastructure on the original host The following attributes should be the same: User name, user ID, group name, and group ID Environment profile, and shell The user may have the same password or a different password than the original user Oracle Application Server 10g: Administration II 35-37 Restoring OracleAS Infrastructure to a New Host (continued) Restore the Oracle system files: - Restore the Oracle system files and Oracle Inventory from your complete cold backup If the oraInventory directory resided in a directory that was separate from the Infrastructure home directory, restore it too Restore the Infrastructure home directory: - Create an empty directory using the same mount point and full path as the original Infrastructure home directory Do not use symbolic links anywhere in the path - Make sure the directory is on a filesystem with enough space to hold the Infrastructure - Make sure the directory is owned by the same user and group as on the original host - To restore the OracleAS Infrastructure home directory: - Restore the backup (tar, cpio) of the Infrastructure home directory from your complete cold backup Be sure your method of restoring the files preserves the original owner, group, permissions, and timestamps - Restore the configuration file backup from your most recent partial online backup - For example, to this using the OracleAS Backup and Recovery Tool: prompt> cd $HOME/infra/backup_tool/AS_BR prompt> /bkp_restore.pl -m restore_config -t config_bkp_2003-11-10_12-19 Restore and recover the Metadata Repository: - Restore and recover the Metadata Repository from your most recent backup - You can perform this step using your own procedures or the OracleAS Backup and Recovery Tool - For example, to this using the tool: prompt> cd $HOME/infra/backup_tool/AS_BR prompt> /bkp_restore.pl -m restore_db - Set file permissions by running the following command as root: prompt> $HOME/infra/root.sh Note: It is not possible to a full backup of the Metadata Repository to a new node because compete recovery is not possible due to the absence of online redo logs A restore is done with a control file or through point-in-time recovery (that is, bkp_restore.pl -m restore_db -c -u ) If this command returns an error and the log shows that the data files were restored and recovered, then issue the SQL command “alter database open resetlogs” and the database will be opened in a consistent state Also, after recovery is complete, create a TEMP tablespace on the recovered database using: SQL> alter tablespace "TEMP" add tempfile 'ORACLE_HOME/oradata/GDB/temp01.dbf' size 5120K autoextend on next 8k maxsize unlimited; Oracle Application Server 10g: Administration II 35-38 Restoring OracleAS Infrastructure to a New Host (continued) Start the OracleAS Infrastructure: - Log in as the user that owns the Infrastructure home directory Set the ORACLE_HOME and ORACLE_SID environment variables - Start the Metadata Repository listener: prompt> $ORACLE_HOME/bin/lsnrctl start - Start the Metadata Repository: prompt> sqlplus /nolog SQL> connect sys/password as sysdba SQL> startup Start Identity Management, and Application Server Control: prompt> $ORACLE_HOME/opmn/bin/opmnctl startall prompt> $ORACLE_HOME/bin/emctl start iasconsole Oracle Application Server 10g: Administration II 35-39 Restoring OracleAS Infrastructure Configuration Files • You may have to restore the OracleAS Infrastructure configuration files if: – OracleAS Infrastructure configuration files are corrupted or lost – OracleAS Infrastructure installation files are available • To restore the configuration files: Stop the OracleAS Infrastructure Restore the configuration files from backup Apply administrative changes made after backup was taken Start the OracleAS Infrastructure 35-40 Copyright © 2004, Oracle All rights reserved Restoring OracleAS Infrastructure Configuration Files Use the following steps to restore OracleAS Infrastructure configuration files Stop the OracleAS Infrastructure instance if it is operational: prompt> cd $HOME/infra/opmn/bin prompt> /opmnctl stopall Restore configuration files: Restore the configuration files from your most recent partial online backup using the OracleAS Backup and Recovery Tool: prompt> cd $HOME/infra/backup_tool/AS_BR prompt> /bkp_restore.pl -m restore_config -t config_bkp_2003-11-10_12-19 Apply recent administrative changes: If you made any administrative changes since the last time you did a online backup used in the step above, reapply them now Start the Infrastructure: prompt> cd $HOME/infra/opmn/bin prompt> /opmnctl startall Oracle Application Server 10g: Administration II 35-40 Restoring Middle Tier to the Same Host • You may need to restore middle tier to the same host when: – You have lost some or all of Oracle software files – Your host system and configuration files are available • Follow these steps to restore middle tier to the same host: Stop the middle-tier instance if it is still running If the instance was associated with an configuration repository, then make sure the corresponding repository instance is operational Restore the middle-tier home directory Start the middle tier 35-41 Copyright © 2004, Oracle All rights reserved Restoring Middle Tier to the Same Host Stop the middle-tier instance if it is still running: prompt> cd $HOME/mi01/opmn/bin prompt> /opmnctl stopall If the middle tier was associated with an OracleAS Infrastructure, then make sure the Infrastructure is up During restoration of the middle tier, the configuration files are synchronized with the OracleAS Metadata Repository Restore the middle-tier home directory: - Restore the backup of the middle-tier home directory from your complete cold backup Be sure your method of restoring the files preserves the original owner, group, permissions, and timestamps - Restore the configuration file backup from your most recent partial online backup prompt> cd $HOME/mi01/backup_tool/AS_BR prompt> /bkp_restore.pl -m restore_config -t config_bkp_2003-11-07_11-21 Start the middle-tier instance: prompt> cd $HOME/mi01/opmn/bin prompt> /opmnctl startall Oracle Application Server 10g: Administration II 35-41 Restoring Middle Tier to a New Host • • You may need to restore and recover a middle-tier installation to a new host when the system hosting the middle tier has a failure Restoring a middle-tier installation to a new host contains the following steps: 35-42 Prepare your host Restore Oracle system files Restore the middle-tier home directory Synchronize the middle tier with the new host Copyright © 2004, Oracle All rights reserved Restoring Middle Tier to a New Host Prepare your host: - The first step is to prepare a new host that has an identical system configuration as the original host Refer to the record you created for the OracleAS Backup and Recovery Tool - On the new host, make sure that the hardware platform and the operating system release and patch levels are identical to the original host - Make sure the entry for the new host in /etc/hosts lists the IP address, hostname, and aliases in the same order as the old /etc/hosts file - Check port usage on the new host Make sure there are not any processes using the same ports as the Oracle Application Server installations you are about to restore If there are, you must reconfigure these processes to use different ports before you begin restoring your Oracle Application Server installations - On the new host, create an operating system user that is identical to the user who installed Oracle Application Server on the original host The following attributes should be the same: user name, numerical user ID, group name, numerical group ID, environment profile, and shell Oracle Application Server 10g: Administration II 35-42 Restoring Middle Tier to a New Host (continued) Note: You can restore the middle tier to a new node with a different hostname and IP address In this case, after full recovery of the middle-tier node, you have to run the hostname/IP change script before bringing up the middle-tier instance Restore Oracle system files: - Create the middle-tier home directory: Create an empty directory using the same mount point and full path as the original middle-tier home directory Do not use symbolic links anywhere in the path Make sure the directory is on a filesystem with enough space to hold the middle-tier installation Make sure the directory is owned by the same user and group as on the original host - Restore the Oracle system files from your complete cold backup - If the oraInventory directory resided in a directory that was separate from the middle-tier home directory, restore that Restore the middle-tier home directory: - Restore the backup (tar, cpio) of the middle-tier home directory from your complete cold backup Be sure your method of restoring the files preserves the original owner, group, permissions, and timestamps - Restore the configuration file backup from your most recent partial online backup prompt> cd $HOME/mi01/backup_tool/AS_BR prompt> /bkp_restore.pl -m restore_config -t config_bkp_2003-11-07_11-21 - If the file-based repository on the original host was lost, you must restore (import) the file-based repository to the new host This step is required only if You are using a file-based repository, you are restoring to a new host, and you are restoring the repository host instance: Stop the DCM daemon on all other instances in the farm by running them following command in the home directory of each instance: prompt> cd $ORACLE_HOME/opmn/bin prompt> /opmnctl stopproc ias-component=dcm-daemon - Restore (import) the file-based repository from the most recent backup to the new host: prompt> cd $ORACLE_HOME/dcm/bin/ prompt> /dcmctl importRepository -file file_name - When you run the importRepository command, the middle-tier instance you are currently restoring on the new host becomes the repository host instance If you intend to continue to use the original host, you must notify the original host that it is no longer the repository host instance To this, run the following command in the middle-tier instance on the original host: prompt> $ORACLE_HOME/dcm/bin/dcmctl repositoryRelocated Oracle Application Server 10g: Administration II 35-43 Restoring Middle Tier to a New Host (continued) - Start the DCM daemon on all other instances in the farm by running the following command in the home directory of each instance (do not start DCM in the instance you are currently restoring): prompt> cd $ORACLE_HOME/opmn/bin prompt> /opmnctl startproc ias-component=dcm-daemon Synchronize the middle tier with the new host: - Set file permissions by running the following command as root: prompt> $ORACLE_HOME/root.sh - If the new host has the same hostname and IP address as the old host, you can simply start the middle-tier instance as follows and you will be finished with the procedure: prompt> $ORACLE_HOME/opmn/bin/opmnctl startall
