Updating SAP ABAP Systems on UNIX and Linux: IBM Db2 for Linux, Unix, and Windows

Checking Cluster Data

You can use the cluster data check integrated in SUM to check all pooled tables or cluster tables in the system.

Context

For example, if you use the Database Migration Option of SUM, you can check all pooled or cluster tables in the source system before the migration.

To use the cluster data check, select the option Check Cluster Data in the initial dialogues of the Software Update Manager that are described in Making Entries for Scenarios Without Configuration File.

This check is similar to the SAP_BASIS report SDBI_CLUSTER_CHECK. It is performed by the R3load executable in discard mode and uses the same technology as the benchmarking tool. In addition to the report SDBI_CLUSTER_CHECK, further reports are available such as SDBI_POOL_CHECK.

However, we strongly recommend checking cluster data with the check integrated in SUM instead of the report SDBI_CLUSTER_CHECK. The integrated check is more performant and the runtime is significantly lower because it can work with highly parallelized processing.

For more information about the cluster data check and the reports, see SAP Note 1784377 Information published on SAP site.

Procedure

  • Option 1 (recommended): Check cluster tables using the built-in cluster data check.

    In the initial dialogs of SUM to get the roadmap, select the scenarios without configuration file and choose Check Cluster Data. Then follow the instructions in the subsequent dialogs.

  • Option 2: Check pool and cluster tables using the reports that are described in SAP Note 1784377 Information published on SAP site.
