Preventing buffer copies to improve performance

You can change the Data Protection for SAP options to prevent copying data buffers, the original data buffers are sent between IBM Storage Protect™ components. This change can improve performance.

Data Protection for SAP uses internal buffers to store and exchange data with the IBM Storage Protect server. When data is sent from one component to another, data buffers are copied by default. Data Protection for SAP can prevent copying data buffers by sending the original data buffers. This process reduces the CPU load of the database server.

If client compression or client encryption are specified in the IBM Storage Protect options file (dsm.sys or dsm.opt), the original data buffers are sent.
