Reducing export time in Unicode migration

[Former Member]

Hi.

We are testing a Unicode migration in our ECC5.0 system. We have realized that the export phase has a very long running time, manly due to CDCLS cluster table.

We think that reducing the size of this table would result in a better performance overall. Anybody knows how to reduce the size of this table effectively? Has anybody encountered this situation?

Thanks and regards.

Hello,

Check this Note 857081 - Unicode conversion: downtime estimate

Hi Raquel

The conversion of cluster tables is more time consuming than the conversion of transparent tables. Cluster tables contain compressed data. Therefore the data needs to be uncompressed first, then it can be converted and finally it needs to be compressed again. This is a CPU intensive operation. Please make sure that you use all available CPU power. The export of some cluster tables (e.g. CDCLS, RFBLG) often determine the total export runtime. Therefore it is recommended to split the standard SAPCLUST package into smaller packages (Java Splitter Tool, note 784118). It is also possible to split single tables.

please contact SAP Consulting via globalization@sap.com if you need to consider this option.

Cheers,

Shyam.
