ONLINE DATABASE REFRESH

(I) Prerequisites in Target System.

1.Ensure the successful Backup of target system.

2. If needed, export user-using transaction SCC8,so that we can import it after refresh using

transactionSCC7.

3.Also note the Background Jobs (SM37), Spool settings (SPAD), RFC destinations (SM59), and

ALE settings (SALE), Instances and Operation Modes (RZ04)(only if needed).

RFC Export

Goto SE01, create transport request (Transport of Copies)

R3TR TABU RFCATTRIB *

R3TR TABU RFCDES *

R3TR TABU RFCDOC *

R3TR TABU RFCSYSACL *

================

SE09 --> Select Modifiable --> Click on Create ---> Transport of Copies --> OK --> Put Short

Description --> OK

Double click in the created request

Now Put

Program ID : R3TR

Object Type : TABU

Object Name : RFCDES (Press Enter)

Double Clieck on RFCDES --> put * in table keys --> Save

Finally Release the request.

4.Note the system modification options inSE06 andSCC4 and saved them .So after refresh justfollow the screen shots and change the options accordingly –own

(II) Procedures in Source system.

1. Log into Source Server as adm.

2. Take:\oracle\ora92\database\init.sap and adjust the following parameter’s

which describes the back up strategy.

backup_mode = all

backup_type = online backup_dev_type = disk/tape

backup_root_dir = :\oracle\\sapbackup

compress = yes/no

3.After setting the above parameters you can go for online backup using anyone of the following

tools:

sapdba (:\usr\sap\\SYS\exe\run).

brbackup (in command prompt).

DB13 transaction (in sapgui).

4.Take transactionDB12and Click on theOverview of Database Backups button and take note

of the exact start time of the Source System’s online backup.

Date: __________________

Time: __________________

5.Take transactionDB12and Click on theOverview of redo log files button. Take note of the ID

number (leftmost column) of the first archive log previous to the start of the Source System’s

online backup. This will be the starting point for restoring the archive logs. Note the log number,

date and time of the first archive log to be restored here:

Archive Log: ______________________

Date: ____________________

Time: ____________________

6. Verify the backup is successfully done inDB12.

7. Create Control file as describe below:

Take the command prompt and entersqlplus.

Typesys@ as sysdba to access database as sys user and enter password. Typealter database backup controlfile to trace; and exit.

Above command will generate a.trc file in

:\oracle\\saptrance\usertrace directory.

Open the.trc file, copy the text from “CREATE CONTROLFILE” until the“;” and paste

it in to new text file and name it ascontrolfile.sql.

Open thecontrolfile.sql file and replace the entire source to target and Edit

theREUSEdatabase command with theSETdatabase command, also change

NORESETLOGS toRESETLOGS and save it

8. Take transactionDB12and Click on theOverview of redo log files button. Take note of the ID

number (leftmost column) of the first archive log immediately after creating the control file. Thiswill be the stopping point for restoring the archive logs. Note the log number, date and time of

the first archive log to be restored here:

Archive Log: ______________________

Date: ____________________

Time: ____________________

(III) Procedures in Target system.

1. Log into Target Server as adm.

2. Copy thecontrolfile.sql from source system to target system.

3. Also copy the generated backup file from the source system to target system.

(:\oracle\\sapbackup).

4. Rename the source with target in the copied backup files and folder.

5. Open the two.andfiles and replace the entire source with target

6. Also replace the path of the source backup directory with the target backup directory in the

.and file, if the directories are in different locations.

7. Shutdown the target server instance.

8. Take:\oracle\ora92\database\init.sap and adjust the following parameter’s

which describes the back up strategy.

backup_mode = all

restore_mode = all

backup_type = online

backup_dev_type = disk/tape

backup_root_dir = :\oracle\\sapbackup compress = yes/no

9. After setting the above parameters you can go for restore using anyone of the following tools:

sapdba (:\usr\sap\\SYS\exe\run).

brrestore (in command prompt).

10. Wait for the successful restore.

11. For applying control files to the restored database, proceed as follows:


Typesys@ as sysdba to access database as sys user and enter password.

Shutdown the database using “shutdown immediate” command.

Type “startup nomount”to start database in nomount mode.

Enter the command@.

After displaying “statement processed”,type the commandalter database open resetlogs;

for opening the database with resetlogs

.

12. If recovery is need for opening database,

Copy the redo logs that we noted in steps II (5) to II (8) from the source

:\oracle\\saparch to target :\oracle\\saparch. Then enter the command“recover database using backup controlfile until cancel” for

recovering database.

13. Shutdown the database.

(IV) Post Processes in Target system.

1. Creating OPS$, etc, (if needed)


Typesys@ as sysdba to access database as sys user and enter password.

Startup the database using “startup” commands.

Enter:

splplus>Create user 'OPS$\adm' identified by

default tablespace psapuser1d temporary tablespace psaptemp;

splplus>Grant dba, connect, resource to 'OPS$\adm' with admin

option;

splplus>Grant connect to identified by sap;

splplus>commit

Note: Check the service sap_. If this service runs the SAPServiceSID

then you also need to create this user in Oracle the same way as you did for adm.

3. In the profile files change the background processes to0 in instance profile (this is to make sure

that no background jobs start running after starting sap)

4.If the environment variabledbs_ora_schema is not set to the owner of the tables, the SAP

system should work with fresh 4.7 installations.

5. Start sap

6. Install the sap license.

Check the existence of license by entering the commandsaplicense –showin commandprompt.

Delete the current license (if exist) by executing the command:saplicense –delete.

Install the license using the command saplicense –install and enter the require

information.

7.Logon to SAP and Check all jobs for the past 5 days for released, ready, and active.

TakeEditmenu --> SelectAll. Then go thru and unselect the eu*, sap*, oh and collector*

jobs. Then select job,released->scheduled

8. Stop sap and Change the number of background work processes to same as before

9. Start sap and Execute the transactionSICK. Also ensure the absence of errors in this

transaction.

10. Check Background Processing:

Take TransactionSM65

From menu chooseGoto -> Additional tests

Selectall, and then pressExecute and Resolve issues if any.

11. Post Installation Processing:

Execute transactionSE06

ChooseDatabase copy or migration

ChoosePost Installation Processing

Do you want to reinstall? Yes

Change originals from? No

transactionSTMS.

TakeOverview->Systems

Go toExtras menu and chooseDistribute TMS Configuration

15. Import User Information:

Before proceeding you need to open the client for changes. You cannot import into

production client.

Note: We don’t need to do it at the OS level. We need to do it from SAP just like any other regular

transport request.

16. Run Post-Client Import Processing:

Use transactionSCC7.

Schedule job in background.

17. Remove TemSe Objects:

Go to TransactionSE14and Enter tableTST03and Press Enter.

Select Radio Button for:Direct

Select Radio Button for:Delete Data (to avoid archiving the data) Click onActivate and Adjust Database andConfirm.
