5.0 Installation Considerations

The following section provides information about prerequisites, configurations, and issues to consider before install the CA ARCserve Backup Client Agents.

5.1 Installation Considerations for the Client Agents

The following section provides information about installation considerations for the CA ARCserve Backup Client Agents.

• If you perform a full node backup on AS400 systems, you must select the Traverse across File System (UNIX System Only) node option on the Miscellaneous tab of the Backup Manager.

5.2 Installation Considerations for the Enterprise Option for SAP R/3 for Oracle (UNIX and Linux)

To back up and restore SAP R/3 for Oracle data, consider the following:

• The CA ARCserve Backup for UNIX and Linux Data Mover option is required.

6.0 General Considerations

The following sections provide general information to consider when using CA ARCserve Backup Client Agents.

6.1 General Considerations for the Agent for Oracle on UNIX Platforms

The following section provides information to consider when using the Agent for Oracle on UNIX platforms:

• Although the Disk to Disk to Tape Option has been added to CA ARCserve Backup, child jobs generated by RMAN use the full backup staging policy. You cannot currently extend incremental or differential staging policies to the child jobs generated by RMAN, although this functionality is expected to be included in a future release.

6.2 General Considerations for the Agent for Oracle on Linux Platforms

The following section provides information to consider when using the Agent for Oracle on Linux platforms:

• Because of a requirement imposed by Oracle, you must add the following to the Common Agent configuration file, agent.cfg, on Red Hat Linux 3.0:

  LD_ASSUME_KERNEL=2.4.19
  

  Add this environment variable to the section for the Agent for Oracle, as in the following example:

  [46]
  	# Oracle Agent
  	NAME    OracleAgent
  	VERSION 16.0
  	HOME    /opt/CA/ABoraagt
  	ENV     CAS_ENV_ORACLE_AGENT_HOME=/opt/CA/ABoraagt
  	#ENV   CA_ENV_NUM_OF_REST_BUFF=
  	ENV     DAYS_ORAGENTD_LOGS_RETAINED=30
  	ENV     DAYS_RMAN_SCRIPTS_RETAINED=30
  	ENV     LD_ASSUME_KERNEL=2.4.19
  	ENV     CAS_INITIATED=1
  	ENV     ORACLE_SHUTDOWN_TYPE=immediate
  	#ENV   NLS_LANG=american
  	ENV     NLS_DATE_FORMAT=MM/DD/YYYY/HH24:MI:SS
  	ENV     LD_LIBRARY_PATH=/opt/CA/ABcmagt:/usr/lib:/opt/CA/ABoraagt:/opt/CA/ABo
  	raagt/lib:/opt/CA/CAlib:$LD_LIBRARY_PATH
  	BROWSER oraclebr
  	AGENT   oragentd
  

  Additionally, you must set this environment variable before starting Oracle.

• Although the Disk to Disk to Tape Option has been added to CA ARCserve Backup, child jobs generated by RMAN use the full backup staging policy. You cannot currently extend incremental or differential staging policies to the child jobs generated by RMAN, although this functionality is expected to be included in a future release.

7.0 Known Issues

The following sections provide information about issues known to exist in this release.

7.1 Known Issues for the Agent for Oracle on UNIX and Linux Platforms

The following issues relating to the Agent for UNIX/Linux are known to exist in this release:

• If you performed backup jobs with the CA ARCserve Backup for UNIX or Linux Agent for Oracle using a version prior to r11.5 and then upgraded to r11.5 or later, you cannot restore the backup sessions using CA ARCserve Backup.
• We recommend that you back up the Oracle RMAN agent using Disk to Disk to Tape feature (Disk Staging). If you chose to back up directly to tape, note you will require more storage media when doing a multichannel backup.
• This release of CA ARCserve Backup supports one (1) password per Oracle encrypted backup.
• When different table spaces are backed up using different passwords, you must restore them in separate jobs by providing the correct passwords.
• This release of CA ARCserve Backup supports Oracle-encrypted backup and decryption restore jobs submitted from the Manager Console (GUI).
• This release of CA ARCserve Backup will not show the lock icon for RMAN-encrypted sessions.
• Avoid changing passwords after a full backup is done. When password must be changed, do so prior to performing a full backup.
• Invalid incremental levels in Oracle 10g:

  • For rotation or GFS-rotation jobs, incremental levels are assigned as follows:

    • full backup = incremental level 0 (RMAN)
    • incremental backup = incremental level 1 (RMAN)
    • differential backup = incremental level 1 cumulative (RMAN)
  • For non-rotation jobs, you must set an incremental value between 0 and 1 if you are running Oracle 10g. If you are running an earlier version of Oracle, set an incremental value between 0 and 4.
• You must use an RMAN Catalog to run jobs with the Oracle option Include Control File Oracle option enabled from the Oracle Restore Manager. If you enabled the control file autobackup feature for the target database before using the Agent for Oracle, use your own RMAN scripts to restore an autobackup of the control file. For more information, see the CA ARCserve Backup Agent for Oracle Guide.
• Compare Media to Disk is not supported on Agent for Oracle sessions.
• Optimize Restore functionality is not supported for the Agent for Oracle.
• The Restore by Media and Restore by Session options are not supported for this release.
• Encryption Oracle data during the backup phase or the migration phase only supports encrypt data at Backup Server, encrypt data at Agent is not supported.
• CA ARCserve Backup does not support restoring multiple, encrypted, Oracle RMAN sessions in a single restore job. You must restore encrypted Oracle RMAN backup sessions as individual restore jobs.
• The Agent can support session passwords if Encrypted data at server side is selected from Global Options during backup.
• You should reboot the machine whenever you install a new Oracle database to avoid problems loading a driver (OCI.DLL).
• If you experience problems expanding the Oracle database after providing the correct login credentials, collapse the machine and then re-expand the tree to refresh the cache.
• You must supply the correct host name when registering the Agent for Oracle nodes in the CA ARCserve Backup database. If the Agent machine has a fully qualified name (computer name + domain name, such as NodeName.ca.com), then the full computer name must be used while registering the Agent node.
• This release of CA ARCserve Backup does not support protecting Oracle 11g Release 2 data stored on computers running AIX 6.1 operating systems.
• For the Agent for Oracle on non-global zones on Solaris 10 (SPARC, x86):

  • If the common agent is not installed in global zones, you must complete the following steps before you install the Oracle Agent in non-global zones:

    • global# mkdir -p /opt/CA/ABcmagt; touch /opt/CA/ABcmagt/caagent
    • global# ln -sf /opt/CA/ABcmagt/caagent /usr/bin/caagent

7.2 Known Issues for the Client Agent for OpenVMS

The following issues related to the Client Agent for OpenVMS are known to exist in this release:

• The Client Agent for OpenVMS does not support incremental and differential backup operations.
• The agent does not support Synonyms or Aliases.
• The agent does not support backup or restore filters.
• Backup jobs cannot be stopped before they finish. To stop a backup job, shut down the agent process on the OpenVMS computer. The agent job is then stopped at the host.
• Restore jobs can be executed without providing the correct session password. Users will still be able to restore, but the backup sessions are not password protected.

7.3 Known Issues for the Enterprise Option for AS/400

The following issues related to the Enterprise Option for AS/400 are known to exist in this release:

• For large backup jobs, disable the File Estimate option in the Backup Manager.
• You cannot browse the AS/400 client tree while the Client Agent for AS/400 is running a backup job.
• If, after ten minutes or more of inactivity, you expand the Client Agent for AS/400 tree, a lost connection message can be generated in the CA ARCserve Backup interface. Click OK to proceed with browsing.
• Whole node backup operations are not supported with the Client Agent for AS400.

7.4 Known Issues for the Client Agent on UNIX and Linux Platforms

The following issues relating to the Client Agent on UNIX and Linux platforms are known to exist in this release:

• On AIX platform, the tcp_nodelayack option prompts TCP to send an immediate acknowledgement, rather than the usual 200 ms delay. Sending an immediate acknowledgement might add a little more overhead, but in some cases, greatly improves performance.
• By default, this option is disabled and it causes the delay acknowledgement within 200 ms in most tcp received during restoration from primary server to AIX client agent. And this causes the restoration speed to become slower than 10mb per minute.

  To improve this, we may enable this option by following the steps below:

  1. Check the current setting:

     # no -a | grep tcp_nodelayack

  2. If the value is zero or not set, set it to 1:

     # no -o tcp_nodelayack=1

7.5 Known Issues for the Enterprise Option for SAP R/3 for Oracle (UNIX and Linux)

The following issues relating to the Enterprise Option for SAP R/3 for Oracle (UNIX and Linux) are known to exist in this release:

• If a SAP backup job fails on the CA ARCserve Backup server (for example, a media error occurs), the SAP backup utility (for example, brbackup) will stop responding and eventually time out. The backup utility behaves in this manner because it cannot detect the status jobs on the backup server. When you encounter this problem, terminate the SAP backup manually, correct the problem, and then resubmit the backup.
• This option does not support using multistreaming when backing up SAP data to data deduplication devices. With multistreaming, CA ARCserve Backup backs up SAP data to multiple devices that reside in different device groups simultaneously. This behavior causes CA ARCserve Backup to ignore the value of DESTGROUP specified in the util_par_file configuration file. As a result, CA ARCserve Backup backs up SAP data to device groups that do not contain deduplication devices.
• If you register a data mover server with a different primary server after you install and configure option, you must reconfigure the option using the sapsetup script. If you do not reconfigure the option, jobs submitted through the affected data mover server will fail.
• Optimize Restore functionality is not supported for the Enterprise Option for SAP R/3 for Oracle.
• Compare Media to Disk functionality is not supported on Enterprise Option for SAP R/3 for Oracle sessions.
• With this option you can back up data stored on UNIX and Linux agents to deduplication devices. However, the option does not support compressing the data during the backup.
• The restoration of SAP R/3 agent databases from the CA ARCserve Backup Restore Manager is not supported. However, you can perform this restoration by using the "brrestore" module from the Command Line. The brrestore module is used to restore database data files, control files, and offline redo log files.
• By default, the network option parameter "tcp_nodelayack" on AIX platforms is set to 0. This default setting may cause restoring SAP data from primary and member server to be slow (less than 10MB/min).

  To remedy this problem, change the setting of tcp_nodelayack to 1 using the following command:

  no -o tcp_nodelayack=1
  

7.6 Known Issues for the Data Mover Option in Non-global Zones on Solaris 10 Platforms

• The Data Mover option is supported in non-global zones on Solaris SPARC 10 Platforms but needs to consider the following to avoid installation error:

  • If the common agent is not installed in the global zone, then create the following folder and link:

    • global# mkdir -p /opt/CA/ABcmagt; touch /opt/CA/ABcmagt/caagent
    • global# ln -sf /opt/CA/ABcmagt/caagent /usr/bin/caagent

    In addition, create a writable folder: /full_path_of_zone/DEV_CA with the root user in the global zone and mount it to /dev/CA in the non-global zone:

    global# zonecfg -z my-zone

    zonecfg:my-zone> add fs

    zonecfg:my-zone:fs> set dir=/dev/CA

    zonecfg:my-zone:fs> set special=/full_path_of_zone/DEV_CA

    zonecfg:my-zone:fs> set type=lofs

    zonecfg:my-zone:fs> add options rw

    zonecfg:my-zone:fs> end

  • If the common agent is installed in the global zone, then it is required that you create a writable folder: /full_path_of_zone/DEV_CA with the root user in the global zone and mount it to /dev/CA in the non-global zone:

    global# zonecfg -z my-zone

    zonecfg:my-zone> add fs

    zonecfg:my-zone:fs> set dir=/dev/CA

    zonecfg:my-zone:fs> set special=/full_path_of_zone/DEV_CA

    zonecfg:my-zone:fs> set type=lofs

    zonecfg:my-zone:fs> add options rw

    zonecfg:my-zone:fs> end
