Overview of standard SAP R/3 system installation with DB2 UDB

A SAP R/3 system is identified by a three character system identifier <SID> and a two digit system number between 00 and 96.

The following information about the directory structure applies to a Central System consisting of the SAP R/3 central instance and database instance installed on a single host. We do not consider the installation of dialog instances on additional systems. We will further assume that the transport host is installed on the same host as the central instance.

The base directories required for the SAP R/3 central instance are /usr/sap for the general SAP R/3 software, and /usr/sap/trans, which contains SAP R/3 software for the transport of objects between SAP R/3 systems. The SAP R/3 software and configuration files are installed in the directory /usr/sap/<SID>. The directory is owned by the user <sid>adm, which belongs to the group sapsys. For each R/3 system there is one DB2 instance db2<sid> that contains the SAP R/3 database <SID> and an administration database ADM<SID> for managing backup images and log files. The db2<sid> directory is owned by the user db2<sid>, which belongs to the group db<sid>adm. db<sid>adm is the SYSADM_GROUP of the DB2 instance.

This results in the following directory structure:

SAP software

/usr/sap

<SID> trans

DB2 instance /db2/<SID>

db2<sid>/NODE0000 log_dir log_archive log_retrieve sapdata1 sapdata2 sapdata3 sapdata4 sapdata5 sapdata6 sapdatat

sqllib

By default all the tablespaces are database-managed storage (DMS), except for the temporary tablespace PSAPTEMP which is system-managed storage (SMS). If you want to use the split mirror copy of the database to take a backup, you should create PSAPTEMP as a DMS tablespace. With DB2 UDB V7.2, you cannot take backups of split mirror database copies unless all the tablespaces are DMS.
