Advanced Restore - SAP MaxDB iDataAgent

Choosing Restore Types

When restoring SAP for MAXDB data, it is important to consider the backup type that was originally performed.

The following table illustrates the types of restores available for each backup type:

Backup Type

Restore Level

Notes

Offline Backup

Restore Entire Database

Recover Database

The database is offline and is consistent, so there is no need for logs.

Online Backup

Restore Entire Database

Restore Logs

Selective Online Full Backup

Restore Entire Database

Validating the Backups

Before you perform a restore operation, you can validate if the backup that you want to restore is accessible, and the data is readable. You need to open a service session to perform the validation.

  1. Open the DBM Command Line Interface and type the following commands to list all of the external backup IDs: 

    dbmcli -d TST -u dbm,dbm –uUTL
 dbmcli on TST>db_admin
 OK
 dbmcli on TST>backup_ext_ids_get BackData2
 OK
 dbmcli on TST>backup_ext_ids_list
 OK
 END

 AVAILABLE|TST 262791520_85712 /sapdb/TST/data/pipe/m1|DATA MIGRATION|2015-02-11 17:52:04|

  2. Open a service session. 

    dbmcli on TST>service_connect
 OK

  3. Use the recover_check command to perform a consistency check of the backup. A 0 return code with the backup details as an output indicates that the consistency check is successful. 

    dbmcli on TST>recover_check BackData2 DATA ExternalBackupID "TST 262791520_85712 /sapdb/TST/data/pipe/m0,TST 262791520_85712 /sapdb/TST/data/pipe/m1" AUTOIGNORE

Restoring to a Different Client (Cross Machine Restore)

In cases when the original client computer is damaged, you need to restore the SAP for MAXDB database to a different host. This is called a cross-machine restore. Whenever you perform such a restore, ensure that the destination machine has sufficient disk space to accommodate the restored database.

Before You Begin

  1. Perform a full backup.

  2. Disable all the backup schedules.

  3. Build a destination computer. The source and destination computer must have the same operating system.

  4. Install the SAP for MaxDB software on the destination client. Configure the destination client so that it has identical DATA volumes and LOG volumes as the source host.

  5. Place the destination database in ADMIN mode.

  6. Install the SAP MaxDB agent on the destination computer.

  7. Configure the database instance on the destination CommServe computer. In the parameter file, add the srcCrossClient parameter.

    For example:

    srcCrossClient
    sybserver5

  8. Define a backup medium on the destination computer by using the medium_put command. For information about how to use the medium_put command, see SAP for MaxDB Configuration.

  9. Configure the SAP MaxDB parameter file to include the srcCrossClient parameter. Set the value to the source client name.

Procedure

  1. If the dbm.knl and dbm.ebf files do not exist on the destination client and if the source client is still available, copy these files if they are available. Otherwise, manually restore the files by using the Backint interface.

    1. Create an input file (for example, "file1.txt") that contains #NULL that you will use with the inquire operation.

      Example

      Windows 
      more file1.txt
#NULL
      UNIX 
      [root@mac1 opt]# cat file1.txt 
 #NULL

    2. Run the inquire operation with the input file to retrieve the job ids. The operation returns of all the backup jobs, ending with the latest backup job. On the command line, type the following substituting the parameters: 

       
      backint.exe -u <database_name> -f inquire -t file -p <parameter_file> -i <input_file>
      Windows 
      C:\Program Files\CommVault\ContentStore\Base>set BI_CALLER=BACKINT_MAXDB

    3. Create an input file for the restore command that contains the last job id. For example, if the last backup job id is1023298_396222, the file looks like:

      UNIX 
      [root@mac1 opt]# cat file2.txt 
 1023298_396222

    4. Run the inquire operation with the input file that contains the last job id, to retrieve the location of the catalog files. On the command line, type the following substituting the parameters: 

       
      backint.exe -u <database_name> -f inquire -t file -p <parameter_file> -i <input_file>

      The history and catalog files found on the source are called D:\sdb\cert1\wrk\dbm.ebf and D:\sdb\cert1\wrk\dbm.knl.

    5. Create an input file that the restore operation will use.

      Option

      File Format

      Restore to same path

      <job id> <location of dbm.ebf file>

      <job id> <location of dbm.knl file>

      Example

      1023298_396222 D:\sdb\cert1\wrk\dbm.ebf

      1023298_396222 D:\sdb\cert1\wrk\dbm.knl

      Restore to a different path without overwriting the original catalog

      <job id> <location of dbm.ebf file> <new location of dbm.ebf file>

      <job id> <location of dbm.knl file> <new location of <location of dbm.knl file>

      Example

      1023298_396222 D:\sdb\cert1\wrk\dbm.ebf D:\new_location\dbm.ebf

      1023298_396222 D:\sdb\cert1\wrk\dbm.knl D:\new_location\dbm.knl

      Restore to a different SID

      Source SID Name = <source SID> whose path = <catalog with source SID directory>

      Destination SID Name =<destination SID> whose path =<catalog with destination SID directory>

      Example

      1023298_396391 D:\sdb\cert1\wrk\dbm.ebf D:\sdb\cert3\wrk

      1023298_396391 D:\sdb\cert1\wrk\dbm.knl D:\sdb\cert3\wrk

  3. Activate the database and recover the full backup. On the command line, type the following. Use a comma to separate each specified ID. 

     
    dbmcli on <SID> db_activate RECOVER BACKData2 DATA ExternalBackupID "ExternalBackupIDN"

    For example, enter the command as shown below:

    dbmcli on cert1 > db_activate recover BackData2 DATA ExternalBackupID "CERT1 1023362_78302 /opt/sdb/data/cert1/files/pipe_mem1,CERT1 1023362_78302 /opt/sdb/data/cert1/files/pipe_mem2"

  4. Restore the incremental backups. On the command line, type the following. 

     
    recover_start BackPages2 PAGES ExternalBackupID "ExternalBackupIDN"

    For example, enter the command as shown below:

    dbmcli on cert2>recover_start BackPages2 PAGES ExternalBackupID "CERT1 1023362_78308 /opt/sdb/data/cert1/files/pipe_mem3,CERT1 1023362_78308 /opt/sdb/data/cert1/files/pipe_mem4"

  5. Restore the logs. On the command line, type the following. 

    recover_start BackLog LOG ExternalBackupID
 recover_replace BackLog ExternalBackupID 
 recover_replace BackLog ExternalBackupID
 recover_ignore

    For example, enter the commands as shown below:

    dbmcli on cert2>recover_start BackLog LOG ExternalBackupID "CERT1 1023362_78322 /opt/sdb/data/cert1/files/pipe_mem5"

ONLINE
Same Operating System - Different Version

Restoring data associated with different versions of the operating system is supported. For example, you can restore file system data secured from a Windows 2000 client computer to a client computer with Windows 2003, or Solaris 7 to Solaris 8, etc. If you plan to do a full system restore on a Windows 2003 Server with an x64 platform, use an SAP for MAXDB iDataAgent for backup on x64 platform. You cannot do a full system restore on an x64 platform if you are using SAP for MAXDB iDataAgent for 32bit platform.

Restoring to a Different Client with Different Database Name (Cross Machine Restore)

In cases when the original client computer is damaged, you need to restore the SAP for MAXDB database to a different host. This is called a cross-machine restore. Whenever you perform such a restore, ensure that the destination machine has sufficient disk space to accommodate the restored database.

Prior to performing a cross-machine restore, perform the following:

  1. Build a secondary (destination) client computer, and assign a different name to this computer. Both the source client computer and the destination client computer must have the same operating system.

  2. Install the SAP for MaxDB software on the destination client. Ensure that the SAP for MaxDB software version is same for the source and destination client.

  3. On the destination client, create the database and volume that are identical to those on the source client. Ensure that the database is in ADMIN mode.

  4. Install the SAP for MaxDB iDataAgent on the destination client and configure the database instance on the CommServe.

  5. Define a backup medium on the destination computer using the medium_put command.

  6. In the parameter file, add the parameters srcCrossClient and srcCrossDbName followed by the name of the source client and the source database:
    For example:

    srcCrossClient

    sybserver5

    srcCrossDbName

    CERT1

  7. From the CommCell Console, configure an instance for the destination client. For instructions, see SAP Max DB Agent Configuration.

  8. From the source client, execute the following backups using the given commands:

    B1 – Full Online Backup

    Execute the following command to perform a full online backup:

Restoring a Full Backup

At times, if the database gets corrupted, you might need to restore the entire database and recover it back to the current state. However, in order to recover a database, you will also need to restore the logs. You can perform a restore operation to restore and recover an entire database. You can restore the database in-place or out-of-place using the same path/destination.

  1. Disable all the backup schedules.

  2. Open the DBM Command line Interface and verify the status of the database. 

    #> dbmcli -d CERT1 -u dbm,dbm -uUTL
 dbmcli on CERT1>db_state
 OK
 State
 ONLINE

  3. MaxDB should be in admin (cold) state to perform a basic restore operation. If the database is in online (warm) mode, execute the following command. 

    #> dbmcli -d CERT1 -u dbm,dbm db_cold

  4. Verify the status of the database again. 

    #> dbmcli -d CERT1 -u dbm,dbm -uUTL
 dbmcli on CERT1>db_state
 OK
 State
 ADMIN

  5. Type the following command to check all backup IDs. The command should return OK. 

    #> dbmcli -d CERT1 -u dbm,dbm -uUTL
 dbmcli on CERT1>backup_ext_ids_get BackData2
 OK

  6. Type the command to list all the External Backup IDs. The command should return OK and display a list of all External Backup IDs. 

    dbmcli on CERT1>backup_ext_ids_list
 OK

    Note: If the command returns CONTINUE instead of END, information on further backups is available in next page. The information is not listed here because of the limited size of the response file. To display the next page of Backup IDs:

    • Repeat the same command.

      (OR)

    • Execute the following command: 

      backup_ext_ids_listnext

Restore from a Secondary Copy

SAP for MAXDB iDataAgent provide the capability of restoring data from secondary copies from SAP command line. This is useful for restoring data when the primary copy is unavailable. To utilize this feature, add the CV_restCopyPrec parameter followed by the copy precedence number 2 into the parameter file prior to running the restore. Ensure that you have run a backup of the SAP MAXDB database prior to starting restore from a secondary copy. Ensure that you have run an auxiliary copy operation after completing the backup.

  1. Disable all the backup schedules.

  2. Open the DBM Command line Interface and verify the status of the database. 

    #> dbmcli -d CERT1 -u dbm,dbm -uUTL
 dbmcli on CERT1>db_state
 OK
 State
 ONLINE

  3. MaxDB should be in admin (cold) state to perform a basic restore operation. If the database is in online (warm) mode, execute the following command. 

    #> dbmcli -d CERT1 -u dbm,dbm db_cold

  4. Verify the status of the database again.

    For Windows:

    dbmcli on CERT1>recover_start BackData2 DATA ExternalBackupID "CERT1 1023298_171929 \\.\pipe\pipe_mem1, CERT1 1023298_171929 \\.\pipe\pipe_mem2”

  9. The restore should complete without any errors. 

    dbmcli on CERT1>exit
 OK

Restore Using a Specific Library or Drive Pool

Data can be restored/recovered from any compatible library and drive type in the CommCell. By default the system automatically identifies and restores/recovers data from any configured library in the CommCell, even if the media is not available in the original library in which the data protection operation was performed. Data Recovery operations use a specific data path - MediaAgent, Library and Drive Pool - to perform the restore operations. When the default options are selected, the system automatically chooses the most appropriate data path. For comprehensive information on choosing an alternate data path, see Data Recovery Operations using Alternate Data Paths.

Note: This feature only applies to tape libraries. The operation fails if the requested data is not available in the disk library that is attached to the specified MediaAgent.

In some situations you may want to use another data path to perform a data recovery operation. In such a situation, you can specify the MediaAgent, Library and/or the Drive Pool.

Consider the following examples:

  • You may want to use a specific MediaAgent to perform the browse and restore operation instead of the system selected default MediaAgent. For example, the default MediaAgent may be busy and you wish to use another MediaAgent which is idle, or you know the library attached to a specific MediaAgent contains the media associated with the data you wish to restore.

  • The default MediaAgent may have a problem accessing the devices (library, drive) and hence you wish to use another MediaAgent sharing the library to perform the browse and restore operation.

Restoring Using Point-in-Time

You can perform a point-in-time restore operation for SAP for MaxDB databases.

Note

You can also perform a point-in-time restore operation using the SAP Database Studio.

Consider the following information for backup jobs.
