3 Executive Summary Dell EMC delivers Database Administrators (DBAs) complete control of DB2 backup, recovery, and disaster recovery with advanced integration between Dell EMC Data Domain Boost, Dell EMC ProtectPoint Technology, and IBM DB2 ACS. This white paper describes the key considerations for Database Agent for DB2, the setup and configuration steps, provides examples of both backup and restore, and gives illustrates how to maintain your environment. Technology Overview Dell EMC ProtectPoint Technology provides up to 20x faster backups and 10x faster recovery while eliminating impact on the DB2 servers. By integrating primary storage (VMAX3, VMAX AF, XtremIO) and protection storage (Data Domain), ProtectPoint technology reduces cost and complexity by eliminating traditional backup applications while still providing the benefits of native backup. Overall, ProtectPoint provides the performance of snapshots with the functionality of backups. There are two data paths ProtectPoint technology can leverage. One for VMAX and one for XtremIO. In the VMAX scenario (shown in Figure 1), DB2 database files are stored on tdevs that are linked to FTS (Federated Tiered Storage) devices which are encapsulated Data Domain vdisk devices. When the DB2 admin triggers a backup the following occurs: Database agent tells DB2 database to quiesce Database agent has SMI-S take a snapshot of the tdevs that store the DB2 database files Database agent tells the DB2 database to unquiesce FTS Technology finds the changed blocks since the last backup FTS devices (encapsulated Data Domain vdisk devices) send the changed blocks to Data Domain to be stored as a full Data Domain static image Figure 1 3 Dell EMC Database Agent for IBM DB2

Therefore, the XtremIO datapath relies on RecoverPoint to trigger snapshots, track the change blocks, and move the data to Data Domain.

4 The data path for XtremIO is a little bit different. XtremIO is architected from the ground up as an All Flash Array, so there is no concept of FTS (Federated Tiered Storage) to track the changed blocks between backups. Therefore, the XtremIO datapath relies on RecoverPoint to trigger snapshots, track the change blocks, and move the data to Data Domain. In this scenario when a DB2 admin triggers a backup the following occurs: Database agent tells DB2 database to quiesce Database agent informs RecoverPoint to snapshot the XtremIO LUNs DB2 database files are stored on Database agent tells the DB2 database to unquiesce RecoverPoint finds the changed blocks since the last backup RecoverPoint sends the changed block to Data Domain via Boost Data Domain stores the data in full static images on Data Domain vdisk devices Figure 2 Perquisite Check List Integrating DB2, primary storage and protection storage with ProtectPoint Technology to enable faster backups and restores requires several prerequisites to be met. Requirements are slightly different depending on the data path being leveraged. For VMAX the following is required: VMAX3 or VMAX AF Data Domain with FC HBAs DB2 host FC zoned to VMAX Solution Enabler VMAX FC zoned to Data Domain which requires 4 DX ports on VMAX A virtual machine for Enterprise Copy Data Management (ecdm) to be deployed A virtual machine for Data Domain Management Center (DDMC) to be deployed 4 Dell EMC Database Agent for IBM DB2

5 For XtremIO the following is required: XtremIO Data Domain with FC HBAs RecoverPoint cluster DB2 host FC zoned to XtremIO RecoverPoint FC zoned to Data Domain A virtual machine for Enterprise Copy Data Management (ecdm) to be deployed A virtual machine for Data Domain Management Center (DDMC) to be deployed Storage Configuration Setup VMAX: This section will go over step by step the setup of VMAX3 or VMAX AF and Data Domain, so ProtectPoint DB2 database agent backups and restore work successfully. At a glance we are manually doing the following steps, and using ecdm to automate the rest as you can see in Table 1: Table 1 Operation ProtectPoint ecdm 1.1 Install SAN connectivity, configure VMAX DX ports, zoning Manual Manual Create user Manual Manual Create DDBoost storage unit Manual Manual Create DD vdisk Pool(s) Manual Manual Create vdisk Devices of same geometry and size as primary LUNs Manual Automated Create vdisk device group for backup and restore Manual Automated Create access group and add initiators to group Manual Manual Add devices to access group Manual Automated Encapsulate the vdisk Devices to VMAX FTS devices Manual Automated Establish and Link devices on VMAX Manual Automated Register Data Domain, XtremIO, DD vdisk Pools, and XtremIO in RecoverPoint Manual Manual Install database agent(s) Manual Manual 5 Dell EMC Database Agent for IBM DB2

6 1. Enable vdisk and boost protocols in Data Domain. VDisk is a scsi protocol that allows Data Domain to create vdisk devices to store the DB2 database files being backed up in their native format which allows for faster restores. a. Example: vdisk enable b. Example: ddboost enable 2. In Data Domain create a user for the vdisk Pool and Storage Unit the DB2 admin will be backing up to. a. Example: user add db2boost 3. Create a Storage Unit with a user assigned. The storage-unit is where logs and catalogs are stored. a. Example: ddboost storage-unit create db2boost user db2boost 4. Create a Data Domain vdisk Pool with same user as the Data Domain Storage Unit. The vdisk Pool is where the database files are stored as static images. a. Example: vdisk pool create db2_vmax user db2boost 5. Create access group so the Data Domain FC HBA ports can see the VMAX DX ports a. Example: scsitarget group create vmax0312_dd5659 service vdisk b. Example: scsitarget group add vmax0312_dd5659 add <dx port initiators> c. Run this command in SYMCLIto discover what the DX port initiators are: symsan sid <> list sanports dx all port all 6. In ecdm create a Protection Plan to automate the rest of the storage configuration for ProtectPoint. The steps that will be automated are the following: a. Creation of vdisk device groups for backup and restore purposes b. Creation of vdisk devices that match in geometric size to the production LUNs being backed up in both the restore and backup vdisk device group c. Adding the vdisk devices to the access group d. Encapsulation of the backup and restore vdisks on the VMAX FTS devices e. The establishment and link between the production devices and the backup encapsulated devices f. Placement of the encapsulated restore devices (vdisk restore devices) in a restore Storage Group on VMAX 7. In ecdm create a Protection Plan like below. Make sure active protection is unchecked and provisioning is checked. a. Set the credentials of the Data Domain Pool in ecdm, so ecdm can access the pool. 6 Dell EMC Database Agent for IBM DB2

7 b. Set the credentials of the Data Domain Pool (db2_vmax) in ecdm, so it can create the vdisk devices and vdisk device groups. 7 Dell EMC Database Agent for IBM DB2

c. Tag the Data Domain pool (db2_vmax) and VMAX Storage Group (db2_bl) with the same tag, so ecdm knows where to create the vdisk devices on DD and the encapsulated devices on VMAX d.

8 c. Tag the Data Domain pool (db2_vmax) and VMAX Storage Group (db2_bl) with the same tag, so ecdm knows where to create the vdisk devices on DD and the encapsulated devices on VMAX d. Assign the Protection Plan created to VMAX Storage Group db2_bl by clicking the shield icon on the far right of the storage group 8. Validate the automated steps ecdm created on Data Domain either in the ecdm Activity Monitor in the UI or manually by doing the following: a. ecdm created backup (ecdm_p db2_bl) device group and restore (ecdm_r db2_bl) device group b. ecdm created 11 vdisk devices in both the restore and backup vdisk device-group that match in geometric size to the production db2 LUNs 8 Dell EMC Database Agent for IBM DB2

13 8. In ecdm create a Protection Plan to automate the rest of the storage configuration for ProtectPoint Technology. The steps that will be automated are the following: a. Creation of vdisk device groups for backup and restore purposes b. Creation of vdisk devices that match in geometric size to the production LUNs being backed up in both the restore and backup vdisk device group c. Adding the vdisk devices to the access group d. A Consistency Group in RecoverPoint with the XtremIO DB2 LUNs that were mapped to RecoverPoint. 9. In ecdm create a Protection Plan like below.

Assign the Protection Plan created to XtremIO Consistency Group

14 c. Tag the Data Domain pools ((bl_xio158_backup_ecdm and bl_xio158_restore_ecdm) and XtremIO Consistency Group (bl_ecdm) with the same tag, so ecdm knows where to create the vdisk devices on Data Domain. d. Assign the Protection Plan created to XtremIO Consistency Group bl_ecdm by clicking the shield icon on the far right of the storage group 14 Dell EMC Database Agent for IBM DB2

15 10. Validate the automated steps ecdm created on Data Domain either in the ecdm Activity Monitor in the UI or manually by doing the following: a. ecdm created backup (ecdm_p db2_bl) device group and restore (ecdm_r db2_bl) device group b. ecdm created 11 vdisk devices in both the restore and backup vdisk device-group that match in geometric size to the production db2 LUNs 11.

Also if the database is stored on VMAX ensure gatekeepers are zoned to the DB2 host, so the host can see the VMAX. 1.

Created 6 volumes in an existing storage group that are mapped to the DB2 server c.

16 b. ecdm created a Consistency Group in ecdm with the XtremIO DB2 LUNs (ecdm_bl_ecdm_protection) DB2 Host Setup The host requires the DB2 database agent and Solution Enabler to be installed if the database is stored on VMAX. Also if the database is stored on VMAX ensure gatekeepers are zoned to the DB2 host, so the host can see the VMAX. 1. Zoned gatekeepers to DB2 server a. Sign onto Unisphere b. Created 6 volumes in an existing storage group that are mapped to the DB2 server c. The gatekeeper creation is a one-time thing. d. Then in vcenter added them as RDM to DB2 server VM. 2. Then do a discover on the DB2 server through SYMCLI: a../symcfg discover -sid <> 16 Dell EMC Database Agent for IBM DB2

17 b. Example of showing the disks VMAX can see on the host:./sympd list 17 Dell EMC Database Agent for IBM DB2

18 3. Next, install the Database Agent on the DB2 server, so it can integrate directly into ACS to create backups and restores. Once it is installed move the configuration file under /home. Then edit the configuration file, so the database agent knows where to send backup and restores. Refer to the Storage Setup section to find the parameter that may be needed for the configuration file. If using the parameters from the examples in the VMAX Storage Setup section the requied parts of the configuration file would look like this. DB2INSTANCE = db2inst1 CLIENT = dmbun141.lss.emc.com DDBOOST_USER =db2boost DEVICE_HOST = DEVICE_PATH =/db2boost VMAX_FASTX_RESTORE_SG = ecdm_db2_bl_rec DEVICE_POOL =db2_vmax DDVDISK_USER = db2boost RESTORE_TYPE_ORDER=PIT PIT or Rollback o PIT is default for RESTORE_TYPE_ORDER. This allows database specific restore. o Rollback will come from the local snapshot from the VMAX if available this is the default This is destructive and will delete everything on the LUN You may require a psrollback.res so that filesystems found on the LUN that you are rolling back are ignored. RESTORE_TYPE_ORDER=rollback VMAX_FASTX_RESTORE_SG = ecdm_db2_bl_rec o Not the default so it has to be set (default NsrSnappSG) o ecdm created this for us DEVICE_POOL: ecdm created 11 vdisk devices in the pool db2_vmax for both backup and restore. RESTORE_DEVICE_POOL = used to restore from DD RESTORE_DEVICE_GROUP = used to restore from DD DDVDISK_USER = is the user the database agent needs to access the Data Domain devices for backup and restore DEVICE_PATH: This is the storage unit the database agent uses to store the logs and catalog information. DEVICE_HOST: The Data Domain CLIENT: The DB2 host 4. Register the Lockbox. a. You need to know the db2 group id if you are not accepting the default of the root group../ddbmadmin -L Provide full pathname for the lockbox, or press Enter to accept the default directory (/opt/dpsapps/common/lockbox): Using the default pathname '/opt/dpsapps/common/lockbox' for lockbox. Provide a group ID for lockbox ownership, or type 0 to accept the 'root user' group as the lockbox owner: 102 Lockbox has been successfully created in the directory '/opt/dpsapps/common/lockbox' with group ownership Dell EMC Database Agent for IBM DB2

19 5. Next, register the Data Domain and RecoverPoint (if database is stored on XtremIO): ~]$ /opt/dpsapps/dbappagent/bin/ddbmadmin -P -z /home/db2inst1/db2.cfg Performing the registration of the device host ' ' for DD Boost user 'db2boost'. Enter password: Confirm password: Logging in to the device host ' ' with DD Boost credentials. Logging in to the device host ' ' with DD Boost credentials was successful. Performing the registration of the device host ' ' for DD VDISK user 'ppuser'. Enter password: Confirm password: Logging in to the device host ' ' with DD VDISK credentials. Logging in to the device host ' ' with DD VDISK credentials was successful. Lockbox directory is '/opt/dpsapps/common/lockbox'. Device host ' ' for DD Boost user 'db2boost' has been registered in the lockbox. Device host ' ' for DD VDISK user 'ppuser' has been registered in the lockbox. 6. Now setup DB2 backup utility parameters, VENDOROPT and LOGARCHOPT. a. As an example for this Database called PLUTO using the configuration file called db2inst1.cfg found in /home/db2inst1/config. i. Make sure to include and run with the db2 userid. db2 update db cfg for PLUTO using 7. Ensure that VENDOROPT has been set by running: db2 get db cfg for PLUTO grep VENDOROPT db2inst1@db2-01:~> db2 get db cfg for PLUTO grep VENDOR First log archive method (LOGARCHMETH1) = VENDOR:/usr/lib/ddbda/lib64/libddboostdb2.so Vendor options (VENDOROPT) 8. Now set the LOGARCHOPT parameters. This is required to point the log backup to the Data Domain. db2 update db cfg for PLUTO using logarchmeth1 VENDOR:/usr/lib/ddbda/lib64/libddboostdb2.so 9. Ensure that LOGARCHMETH has been set by running: 19 Dell EMC Database Agent for IBM DB2

20 db2 get db cfg for PLUTO grep LOGARCH scripts]$ db2 get db cfg for PLUTO grep LOGARCH First log archive method (LOGARCHMETH1) = VENDOR:/usr/lib/ddbda/lib64/libddboostdb2.so Archive compression for logarchmeth1 (LOGARCHCOMPR1) = OFF Options for logarchmeth1 (LOGARCHOPT1) Second log archive method (LOGARCHMETH2) = OFF Archive compression for logarchmeth2 (LOGARCHCOMPR2) = OFF Options for logarchmeth2 (LOGARCHOPT2) = 10. Set Retention to 14 days db2 update db cfg for PLUTO using num_db_backups 14 db2 update db cfg for PLUTO using rec_his_retentn 14 db2 update db cfg for PLUTO using auto_del_rec_obj on 11. Restart the DB to activate these changes. db2 force applications all db2 deactivate db PLUTO db2 backup db pluto to /dev/null (only required the first time you setup logarchmeth) db2 activate db PLUTO DB2 Backup with Database Agent Now, it is time to run a backup! Here is an example of a backup command using the ProtectPoint Technology to create a snapshot of the DB2 LUNs on VMAX or XtremIO that send the changed blocked to Data Domain: Now, try a restore. db2 backup db PLUTO online use snapshot library /opt/dpsapps/dbappagent/lib/lib64/libddboostdb2.so 1. First determine the backup to restore from: 20 Dell EMC Database Agent for IBM DB2

21 db2acsutil LOAD /opt/dpsapps/dbappagent/lib/lib64/libddboostdb2.so options query snapshot db PLUTO 2. Then run a restore. It is the same command for PIT restore or Rollback restore. What determines which restore will happen depends on how the configuration file is set. db2 restore db pluto use snapshot library /opt/dpsapps/dbappagent/lib/lib64/libddboostdb2.so taken at LOGTARGET include force 3. If restoring over top of the existing database with rollback: date; db2 restore db pluto use snapshot library /opt/dpsapps/dbappagent/lib/lib64/libddboostdb2.so taken at LOGTARGET include force replace existing; date 4.

22 Last committed transaction = UTC DB20000I The ROLLFORWARD command completed successfully. 5. To delete a snapshot query the snapshots taken to determine the one to delete: db2acsutil LOAD /opt/dpsapps/dbappagent/lib/lib64/libddboostdb2.so options '@/home/db2inst1/db2.cfg' query snapshot db PLUTO [db2inst1@dmbun141 ~]$ db2acsutil LOAD /opt/dpsapps/dbappagent/lib/lib64/libddboostdb2.so options '@/home/db2inst1/db2.cfg' query snapshot db PLUTO Instance Database Part Image Time Host First Log ========== ========== ==== ============== ========== ========== db2inst1 PLUTO db2inst1 PLUTO Then delete: db2acsutil LOAD /opt/dpsapps/dbappagent/lib/lib64/libddboostdb2.so options '@/home/db2inst1/db2.cfg' delete snapshot db PLUTO taken at Troubleshooting The first thing you do is enable traces so that the correct data is collected and you can review the errors in the ProtectPoint logs. Within the db2.cfg file comment out the following parameters for debug and enable level 9 and add in the Proxy Pfile location and name. DEBUG_LEVEL = 9 DPRINTF = true PROXY_PFILE=/home/db2inst1/pfile.cfg Common Errors A. Reason Code 11 generally caused due to: a. ddbsm daemon is NOT started b. Issues in db2.cfg file. c.
