Unicode-Conversion using Socket-Option possible ?


we plan to do a unicode-conversion.

System is DB2 on AIX.

In the guide from IBM regarding Copy-Optimization there is a info, that the socket-Option will bring a reduction of runtime.

But in Note 2311023 there is the hint, that it's not possible to use the socket-Option with unicode-conversion.

Does someone know, which info is correct ?

    Hi Christoph,

    Socket option is useful incase you want to perform parallel export-import during unicode coversion or system migration.

    Socket option is preferred in case of Windows environment.

    In case you have source and target on Unix environment, you can very well have NFS mount created of the export directory and mount it on the target server. You may still use parallel export-import method to reduce the downtime.

    So inorder to reduce the overall downtime you may implement downtime reduction techniques

    Some of them are listed below

    1) Use of parallel export/import

    2) Rampup the CPU and Memory resources of source and target servers

    3) Implement database specific tuning parameters suggested by SAP for migration

    4) Have DB statistics updated

    5) Implement latest R3* tools for migration

    6) Use of table and package splitting

    You may read through SAP guides and SDN for more inputs on optimization.
