Recover a Full+Incremental backup image of other SAP databases to a new target

The following sections include information on recovering SAP ASE, SAP IQ, and SAP MaxDB databases from a Full+Incremental backup image to a new target.

Procedure

To restore a file-based backup image to a new target, follow these instructions:

From the App Manager Applicationslist, right-click the protected database and select Access.

Note: You can use the Managed Backup Planstatus filter to show only protected databases.
Select the latest snapshot to recover and click Mount.
Provide a mount point under mount location, for example: /mymountpoint .

The database backup is mounted under /mymountpoint and the log backup is mounted under /mymountpoint_archivelog .

Retrieve the JobID of the mount from /var/act/log/UDSAgent.log by running the following command:

  grep 
  
 "mount -t " 
  
 / 
 var 
 / 
 act 
 / 
 log 
 / 
 UDSAgent 
 . 
 log 
  
 | 
  
 grep 
  
 - 
 w 
  
 "(mountPoint provided in step 3)" 
 | 
 tail 
  
 - 
 1

For example:

  # grep "mount -t " /var/act/log/UDSAgent.log| grep -w "/db2mnp" |tail -1

ARCHIVELOG_MNT is equal to _archivelog. Refer to step three.

  cd

 dump

Run the script from command line as root.
Unmount the mounted dump snapshot image.

Required script

Before you can mount a database to a new target, you must prepare a script.

SAP ASE

   
/act/custom_apps/sybase/dump/ACT_SYBASE_dumprestore_newTarget.sh  
 SYBOSUSER 
  
 SRC_SYBASE_SQLD 
  
 TARGET_DB_USER

 TARGET_MNT_PNT 
  
 SRC_DBNAME 
  
 UNTIL_TIME 
  
 BEGIN_TIME 
  
 LOG_BKP_MNTPT 
  
 SRC_PAGE_SIZE

Connect to the SAP ASE instance and confirm that the databases are recovered and online.

You can get these values by running the following commands:

DUMPBKPLOC:

 df  
-h  
 | 
  
grep  
<DUMPBKPLOC>  
 | 
  
awk  
 '{print $NF}' 
cat  
/var/act/log/UDSAgent.log  
 | 
  
grep  
-w  
<DUMPBKPLOC>  
 | 
  
tail  
-1  
 | 
  
cut  
-d ']' 
  
-f2  
 | 
  
cut  
-d ' ' 
  
-f2

JobID:

 cat  
/var/act/log/UDSAgent.log  
 | 
  
grep  
<JOBID>  
 | 
  
awk  
-F "disk at " 
  
 '{print $2}'

MANIFEST_FILE_LOC:

 cat  
/var/act/log/UDSAgent.log  
 | 
  
grep  
-i  
 "Manifest_File_" 
  
 | 
  
awk  
-F "disk at " 
  
 '{print $2}'

LOG_BKP_MNTPT:

 df  
-h  
 | 
  
grep  
 "_archivelog" 
  
 | 
  
awk  
 '{print $NF}'

BEGIN_TIME:

 cat  
/var/act/log/UDSAgent.log  
 | 
  
grep  
 "BEGIN_TIME" 
  
 | 
  
awk  
-F "BEGIN_TIME=" 
  
 '{ print $2 }' 
  
 | 
  
cut  
-d ' ' 
  
-f1-2  
 | 
  
cut  
-d '"' 
  
-f2

SRC_DB_VERSION:

 dbmcli  
-d  
<SRC_DBSID>  
dbm_version  
 | 
  
grep  
 "VERSION" 
  
 | 
  
awk  
-F "= " 
  
 '{print $2}'

Connect to the MaxDB instance and confirm that the databases are recovered and online:

   
dbmcli  
-d  
<TARGET_SERVER_NAME>  
-u  
<TARGET_DB_USER>,<TARGET_DBUSER_PASSWD>
