Oracle: Suppressing Long-Running Phases

If your source database is Oracle, you can suppress long-running phases before you start the update.

Context

During the update with DMO, the following phases can be long-running:

  • EU_CLONE_DT_SIZES

  • EU_CLONE_UT_SIZES

In the course of these phases, the system updates the database statistics regarding the usage of space that the tables need on the database. The aim is a better distribution of the tables during the system cloning. Before you start the update, you can suppress these long-running phases using the following procedure.

Procedure

  1. Log on to the host where the Oracle database instance is running.

    Use user ora<dbsid> for UNIX system or user <sapsid>adm for Windows.

  2. Open a command prompt and execute the following command:

    brconnect -u / -c -f stats -o <schema_owner> -t all -f allsel,collect,space –p 8

  3. Add to file SAPup_add.par the following line:

    /ORA/update_spacestat = 0

    The file SAPup_add.par is located in the subdirectory bin of the SUM directory. If this file does not exist yet, create it.
