ACSLS and the database MUST be in what mode to accomplish a restore?

  1. Both stopped

  2. ACSLS down, database up

  3. ACSLS up, database down

  4. Both running

Answer: A

Explanation: To restore the ACSLS database from the default tape device attached to the ACSLS server after a databasefailure, do the following:

->Login asacsss

->Shut down ACSLS: kill.acsss

3.

Shut down the database: db_command stop

4.

Ensure any existing redo log files are available to the database system.

5.

Make sure the most current backup tape is write-protected, then insert it into the tape device.

6.

Enter the following command: rdb.acsss

Depending on the nature of the database problem, the utility may prompt you for additional information.

7.

Wait for the following prompt:

After performing a successful Oracle database recoveryyou should do a database backup. This will ensure yourability to recover again should you have another databasefailure. Do you want to do this database backup now?

8.

Remove the tape from the drive and insert a new backup tape. 9.

Enter quot;yquot;and press Return to start the backup. 10.

Wait for the backup to complete. Remove the tape from the drive, write protect it, label it with the currentdate, and store it in a safe place.

11.

To start ACSLS, enter the following command: rc.acsss

  5. Maintain sufficient number of scratch cartridges on each rail.

Answer: A,C,D,E

Question No: 24

Identify two high availability features that are unique to Oracle-StorageTek Enterprise libraries.

  1. Redundant Power and Hot-Swappable Drives

  2. Redundant CAPs and Hot Swappable Control Cards

  3. Hot Swappable Redundant Robotics and Control Cards

  4. Hot Swappable Drives and Redundant CAPs

  5. Redundant Robotics and Hot Swappable Drives

Answer: C

Explanation: Industry-leading availability with redundant and hot-swappable robotics and library control cards

Note:When you need the data, you need the data-especially when it involves financial, telecommunications, or government information. StorageTek Enterprise Library Software helps you to take steps to recover faster and to improve day-to-day reliability and availability

with the following:

  • Enhanced disaster recovery. Features electronic import/export capability to enable an unlimited number of virtual tape volumes to be created in multiple locations.

  • Higher availability clustering solution. Expands cluster capability up to four Virtual Tape Storage Subsystems.

    Question No: 25

    When configuring drives in logical libraries which of the following is false?

    1. To assign multiple drives to a logical library, the drives must be located in the same ACS.

    2. Drives may be shared across multiple logical libraries.

    3. Both LTO and Enterprise drives may be configured into logical libraries.

    4. Drives may only be added to logical libraries through the ACSLS GUI.

    Answer: A Explanation:

    Note:When partitioning the StorageTek SL8500, SL3000 or SL500

    libraries into logical libraries, one can assign volumes and drives to the logical library to enable library consolidation, gain capacity on demand, and allow only the client connected to the logical library to access those volumes and drives.

    Note: logical library

    A virtual representation of a physical library. Synonymous with virtual library partition.

    Question No: 26

    How would you generate a list of the EHY100-WHY299 tapes in the LSM?

    1. Log in as acssa, issue a “query vol all”, and then a “grep WHY100-299”

    2. Log in as acssa, issue a “volrpt -zs”, and then a “grep why1”

    3. Log in as acssa, enter a “volrpt -v why”, qand then a “grep WHY100-WHY299”

    4. Log in as acssa and issue a “volrpt-v WHY100-WHY299”

    Answer: D

    Explanation: The volrpt utility creates a volume report.

    -v

    restricts the report to the specified volumes (or volume ranges). You can specify a single vol_id, a list of vol_ids separated by blanks, or a volume range indicated by vol_id-vol_id.

    Use the volrpt utility to create a report of library cartridges, including their physical location, history, attributes, and use.

    Question No: 27

    To continue the install process, in which directory should the ACSLS install scripts be loaded?

    1. /export/home/backup

    2. /export/home/ACSSS/bin

    3. /opt/StorageTek/ACSLS/install

    4. /export/home/ACSSS/install

      Answer: D

      Explanation: Installing ACSLS Software via install.sh

      1. Change directories:

        cd /export/home/ACSSS/install

      2. To initiate the installation shell script, enter

        /install.sh Etc.

        Question No: 28

        Using ACSLS, what are the correct steps to create a pool 5 and add cleaning cartridges to that pool?

        1. Define pool 5, set scratch on, and then set clean for volume range

        2. Define pool 5, set scratch off, and then set clean for volume range

        3. Define pool 5 and set clean for volume range

        4. Can#39;t define clean tapes to a specific pool

          Answer: C

          Explanation: To define cleaning cartridges to ACSLS:

          1. Make the CAP ready for entry.

            See “Entering Cartridges” on page 86 for more information.

          2. Enter the cleaning cartridges.

            The cmd_proc displays messages with the cartridge IDs of the cartridges you enter.

          3. To set the cleaning cartridge attribute: set clean max_usage vol_id | volrange Where:

            max_usage is the number of times a cleaning cartridge is used before ACSLS stops selecting the cartridge to clean cartridges.

            vol_id | volrange specifies the cleaning cartridge or range of

            cartridges that you entered in Step 2.

            Note 1: The set clean command sets cleaning cartridge attributes.

            Format

            set clean max_usage | off vol_id | volrange

            Options max_usage | off

            specifies the number of times a cleaning cartridge is used before ACSLS stops selecting the cartridge to clean drives. off specifies that ACSLS will not select the cartridge and redefines the cartridge as a data cartridge.

            Note: Use the set clean command to set the number of times ACSLS will select a cleaning cartridge. You also use set clean to set a cartridge#39;s cleaning

            cartridge attribute off, which you do if you have incorrectly defined a data cartridge as a cleaning cartridge.

            Question No: 29

            Which SL3000 configuration will in general provide the best performance?

            1. Base CEM CEM CEM

            2. CEM CEM CEM Base

            3. CEM DEM Base CEM

            4. CEM DEM CEM

    Answer: A

    Explanation: The below figure is an example of how the SL3000 uses CenterLine Technology to help balance the workload and

    improve performance. Addressing and Panel Numbering

    Question No: 30

    What is the correct procedure to enable ACSLS automatic backups?

    1. Log in as quot;rootquot; and issue the quot;db_command bkupquot; instruction

    2. Log in as quot;acsssquot; and run quot;bdb.acsssquot; with option #5

    3. Log in as quot;acsssquot;, idle ACSLS, Stop ACSLS, then issue acsss_config

    4. Log in as quot;acsssquot;, enter an quot;acsss_configquot;, and select option #5

    Answer: D

    Explanation: Setting Automatic Backup Variables

    Option 5 allows you to set or change the following automatic backup variables:

  • Prompt: Would you like to modify the automatic backup settings? ( y or n) Variable: None. The automatic backup settings are saved in crontab. Please use acsss_config to modify these settings.

    Valid options are:

  • Y – If yes, you are asked if you want to back up everyday. If “yes”, then you must enter the time in HH:MM format.

    If no, you must select the day(s) of the week to back up. Then you must enter the time in HH:MM format.

  • N – you go to the next question regarding the retention period of SDMmanaged database backup files.
