Managing Serviceguard Extension for SAP, December 2007

Planning the Storage Layout
Database Instance Storage Considerations
Chapter 2 75
Table 2-10 shows the file system layout for SAPDB clusters.
NOTE In HA scenarios, valid for SAPDB/MAXDB versions up to 7.6, the
runtime directory /sapdb/data/wrk is configured to be located at
/sapdb/<DBSID>/wrk to support consolidated failover environments
with several MAXDB instances. The local directory /sapdb/data/wrk
though is still referred to by the VSERVER processes (vserver,
niserver), which means VSERVER core dump and log files will be
located there.
