Recover SAP IQ and SAP MaxDB databases from a volume-based backup image to a new location-Backup and DR-Google Cloud

Recover SAP IQ and SAP MaxDB databases from a volume-based backup image to a new location

Both these procedures require you to customize and run a config file.

The following sections describe how to recover a volume-based backup image of an SAP IQ or SAP MaxDB database to a new location.

To recover a volume-level backup image of an IBM Db2, MariaDB, MySQL, PostgreSQL, SAP ASE, SAP IQ, or SAP MaxDB database to a new target, you can also use the instant mount and migrate of a database to a new target procedure.

Note: Mount and migrate is a quick mount; the database is immediately available from the staging disk, then the data moves in the background from the staging disk to the target storage. If users are active in the database, this takes time and impacts performance.
The restore procedures on this page keep the database down for the entire time of the restore procedure, often some hours, but at the end the database is available on the target storage at full performance, with no impact of background migration or reading from a staging disk.

Recovery procedure

To recover a volume-level backup image to a new target, follow these steps:

From the App Manager Applications list, right-click the protected database and select Access. You can use the Managed Backup Plan status filter to show only protected databases.
Select the latest snapshot to recover, and choose Mount.
Provide a target mount point under mount location, for example, /dmpRstNew. This is used as the variable TARGET_MNT_PNT.

The database backup is mounted under /dmpRstNew (TARGET_MNT_PNT) and the log backup is mounted under /dmpRstNew_archivelog (LOG_BKP_MNTPT).
Log into the database server as root. Change the directory to /act/custom_apps/<database type>/restore.
Run the script.
SAP IQ
Script name: act_sybaseiq_lvm_customdb_recovery.sh

Script location: /act/custom_apps/sybaseiq/restore

Script:
```
/act/custom_apps/sybaseiq/restore/act_sybaseiq_lvm_customdb_recovery.sh
TARGET_MNT
OSUSER
CATALOG_DB_FILE
SRC_DB_DBA_USER
SRC_DB_DBA_PWD
LOG_BKP_MNTPT
RECOVERY_TIME
JOBID
INCR_BKP_LOC
```
Variables for the script:
- TARGET_MNT: The mount point provided during the mount job from Step 3
- OSUSER: The OS user of the target SAP IQ database
- CATALOG_DB_FILE: The source database file full path, such as /lv3Data/lv3DB/data/lv3DB.db
- SRC_DB_DBA_USER: Target utility db user
- SRC_DB_DBA_PWD: Target utility db password
- LOG_BKP_MNTPT: Get this from the mount point provided during the mount job, followed by _archivelog, for example /SDBR_archivelog
- RECOVERY_TIME: (Optional) The time of the last known good database and logs desired recovery time in the format "YYYY-MM-DD HH:MM:SS"
- JOBID: The mount job id (from the management console, Monitor > Jobs tab) in the format Job_1479897
- INCR_BKP_LOC: Incremental backup file path, for example /act/tmpdata/Job_1479897/INC_BKP.1 always /act/tmpdata//INC_BKP.1
After the script has run, connect to the IQ database and confirm that the databases are recovered and online.

SAP MaxDB
Script name: /var/act/scripts/ACT_MAXDB_lvmRestore_newTarget.conf

Script location: /act/custom_apps/maxdb/restore

Script:
```
  /act/custom_apps/maxdb/restore/ACT_MAXDB_lvmRestore_newTarget.sh
  OSUSER
  TARGET_SERVER_NAME
  TARGET_DB_USER
  TARGET_DBUSER_PASSWD

  MANIFEST_FILE_LOC 
  SRC_DB_VERSION
  ACT_JOBNAME
  TARGET_MNT_PNT 
  LOG_BKP_MNTPT
  UNTIL_TIME
  BEGIN_TIME
```
Variables for the script:
- OSUSER: The OS user of the target MaxDB database
- TARGET_SERVER_NAME: The SID of the target MaxDB database
- TARGET_DB_USER and TARGET_DBUSER_PASSWD: The DBM username and password for the target MaxDB database. These must be the same as source DBM username and password. You can change the password after the restore operation is finished.
- SOURCE_DBSID: SID of the source MaxDB database
- MANIFEST_FILE_LOC: the full path to Manifest_File_SLD
- SRC_DB_VERSION: The version number of the source MaxDB database
- ACT_JOBNAME: The mount job id (from the management console, Monitor > Jobs tab) in the format Job_1479897
- TARGET_MNT_PNT: The mount point provided during the mount job (from the management console, Monitor > Jobs tab)
- LOG_BKP_MNTPT: Get this from the mount point provided during the mount job, followed by _archivelog, for example /SDBR_archivelog
- UNTIL_TIME: The desired time for the recovery to be finished, in the format "YYYY-MM-DD HH:MM:SS" (from the management console, of the mounted backup image)
- BEGIN_TIME: The time to start the recovery, in the format "YYYY-MM-DD HH:MM:SS" (from the management console, of the mounted backup image)
Connect to the MaxDB database and confirm that the databases are recovered and online:
```
  dbmcli -d TARGET_SERVER_NAME -u TARGET_DB_USER,TARGET_DBUSER_PASSWD db_state
```
After the database is restored, take a dummy or dump database backup to generate a backup history point in backup_history_list, which is required to take log backups. For example, the following:

dbmcli -d >MAXDB_KEY -uUTL -c backup_start DATA AUTOIGNORE

Without this, future volume level backups fail with the error fail to trigger autolog backup template.
Unmount the mounted snapshot image.

Change the password

In some cases, you may need to change the database password.

SAP IQ

Log into the target database. For a database named TARGET_SERVER_NAME, with db user SRC_DB_DBA_USER and password SRC_DB_DBA_PWD, the command to log in is as follows.
```
dbisql -nogui -onerror exit -c 'uid=SRC_DB_DBA_USER;pwd=SRC_DB_DBA_PWD;dbn=TARGET_SERVER_NAME;eng=TARGET_SERVER_NAME;'
```

Run the following command to change password.

ALTER USER actuser IDENTIFIED BY new_password

dbisql -nogui -onerror exit -c 'uid=actuser;pwd=new_password;dbn=TARGET_SERVER_NAME;eng=TARGET_SERVER_NAME;'

SAP MaxDB

To change the password, log into the target db as DBM user:
```
dbmcli -d TARGET_SERVER_NAME -u TARGET_DB_USER,TARGET_DBUSER_PASSWD
user_changepwd dbm <new_password>
```
For example, for a DBM user changing the password from abcdef to fedcba, log in:

dbmcli -d glxn -u dbm,abcdef
Run the following command:

user_changepwd dbm abcdef
Log in again with the new password:

dbmcli -d glxn -u dbm,fedcba
