    Dear koganti

    Before doing a client copy, you need to prepare the following :-

    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.

    Regards

    George
