Querying and Restoring Data and Log Backup Images on UNIX

You can can use the db2util.sh on UNIX to query, and then restore the backup images to a disk. You must be a valid DB2 user to run this DB2 utility. The Commvault user must have the browse and view capability to query DB2 backup jobs.

Procedure

  1. On the command line, use qlogin from the software_installation_directory/Base directory, and then go to the software_installation_directory/iDataAgent directory, where db2util.sh resides.

     
    su – db2instance_name
cd software_installation_directory/Base
./qlogin –cs commserve_name -u commcell_user_name
cd software_installation_directory/iDataAgent

  2. On the command line, type the following command to see the script options.

    ./db2util.sh -h

    For information about the query options, the restore options, and the input file parameters, see Options and Input File Parameters.

  3. On the command line, run the script to query the data or log backups.

     
    ./db2util.sh -q LOG | DATA |ALL -d db2_database_name -s db2_MultiNode_instance_name -c db2_MultiNode_pseudo-client_name [-i commvault_instance_name] [-f start_time] [-t end_time]

  4. On the command line, run the script to restore the backups to disk.

     
    ./db2util.sh -r JOB|LOG -d database_name <[-j jobId] | [-f start_log_sequence_number -t end_log_sequence_number]> [-s source_db2_instance_name] [-p restore_directory] [-c client_name] [-k target pseudo-client name] [-n DPF] [-i Commvault_instance_name]

  5. After the job completes, use the qlogout command.

     
    qlogout [-cs commserve] [-all] [-tf tokenfile] [-tk token] [-h]

Examples

Querying the data and log backups

Use the following command to query data.

 
/db2util.sh -q data -c db2_MultiNode_pseudo-client_name -s db2_MultiNode_instance_name -d database_name [-i commvault_instance_name]

Use the following command to query logs.

 
/db2util.sh -q log -c db2_MultiNode_pseudo-client_name -s db2_MultiNode_instance_name -d database_name [-i commvault_instance_name]

Use the following command to query both data and logs.

 
/db2util.sh -q all -c db2_MultiNode_pseudo-client_name -s db2_MultiNode_instance_name -d database_name [-i commvault_instance_name]

Use the following command to query both data and logs in a specific time range:

 
/db2util.sh -q ALL -c db2_MultiNode_pseudo-client_name -s db2_MultiNode_instance_name -d database_name [-i Commvault_instance_name]  -f '04-11-2019 10:00:00' -t'04-11-2019 11:00:00'
Restoring to a disk

Use the following command and options to restore a backup image to a disk:

 
./db2util.sh -r JOB|LOG -d database_name <[-j jobId] | [-f start_log_sequence_number -t end_log_sequence_number]> [-s source_db2_instance_name] [-p restore_directory] [-c client_name] [-k target pseudo-client name] [-n DPF] [-i Commvault_instance_name]
Restoring to a disk using an input file

Use the following command and options to restore a backup image to a disk by using an input file that includes all the commands.

 
./db2util.sh -a input_file [-i commvault_instance]

Example

# su - db2inst5
$ cd /opt/Commvault/iDataAgent
 ./db2util.sh -q all -c DB2DPF_DB2DPFMAC1_1051 -s part1051 -d galaxy -i Instance001 
 Input:: DBNAME=galaxy 
 INSTANCE=Instance001

Restoring logs

Use the following command to restore a backup image to a disk:

 
/db2util.sh -r LOG -d database_name [-o target_database_name] [-i Commvault_instance] [-f start_log_sequence_number] [-t end_log_sequence_number] [-c client name][-n DPF]

In the following example, the parameters are on the command line.

/db2util.sh -r LOG -d partdb -o partdb -s part1051 -c DB2DPF_DB2DPFVM1_1051 -i Instance001 -f 390596 -t 390645 -n DPF -k DB2DPF_DB2DPFVM1_1051
Restoring by using the log sequence number
./db2util.sh -r LOG -f 1133 -t 1142 -c DB2DPF_DB2DPFMAC1_1051 -s part1051 -d galaxy -i Instance001 -k DB2DPF_DB2DPFMAC1_1051 -n DPF

By default, the software restores the log sequence archive files to the DB2 retrieve path that you specified when you installed the software.
