First be sure that you have enough space in the tablespaces. If not extent tablespaces.

It's better to copy the client, when there is no user activity both in the source client and if possible in the system. This provides data consistency and improved system performance.

1. Find the source client space with the client size custom program which can be implemented using the rel. note:

Find the space of the client - '0118823'. This will give you the size of the source client.

2. If your are on Unix OS, adjust all the file systems according to PRD file system to fit the PRD client in DEV

client based on space requirements also.

3. You can do the client copy by remote or export/import client.

Remote method is not preferred if you are doing a large client copy.

Do a client export/import.

4. To speed up the export/import, use R3trans export/import for the clustered tables.

Please find the rel. notes related to performance improvements for cluster tables in OSS.

5. Do import and post processing.

Note: Export may take 10 to 20 hr. for 50gb of data

import may take 4 days and post import will take 8 to 15 hr. for 50gb of data. And it all depends on

your system performance.

Please refer OSS rel. notes for the few RZ10 parameters which needs to be set for cluster tables to speed up the process.

Check the space your system and no user active when you create a client.

Procedure

1. Maintain the new client with transaction SCC4.:

2) Set the profile parameter login/no_automatic_user_sapstar to 0..

3. Log on to the new client with user SAP* and password PASS.

4. Copy client 000 with transaction SCCL for Local client copy and profile SAP_ALL.

5. Check the log files with transaction SCC3.:

for Remote client copy SCC9 and maintain rfc connection.
