chfs -a size=14000000 /db2/TS1/db2ts1/NODE0000

Mount the file systems:

mount /usr/sap

mount /db2/TS1/db2ts1/NODE0000 mount /db2/TS1/sapdata1 mount /db2/TS1/sapdata2 mount /db2/TS1/sapdata3 mount /db2/TS1/sapdata4 mount /db2/TS1/sapdata5 mount /db2/TS1/sapdata6 mount /db2/TS1/sapdata7 mount /db2/TS1/log_dir

Change ownership of the file systems to the SAP administrative user and DB2 instance owner respectively (users ts1adm in group sapsys and user db2ts1 and group dbts1adm in this example):

chown ts1adm:sapsys /usr/sap

chown db2ts1:dbts1adm /db2/TS1/sapdata1 chown db2ts1:dbts1adm /db2/TS1/sapdata2 chown db2ts1:dbts1adm /db2/TS1/sapdata3 chown db2ts1:dbts1adm /db2/TS1/sapdata4 chown db2ts1:dbts1adm /db2/TS1/sapdata5 chown db2ts1:dbts1adm /db2/TS1/sapdata6 chown db2ts1:dbts1adm /db2/TS1/sapdata7 chown db2ts1:dbts1adm /db2/TS1/log_dir

6.Install DB2 on both the Primary and Backup server if this is not already done. Further information on installing DB2 can be found in the DB2 UDB documentation.

7.Install the SAP R/3 system as Central Instance (database server and SAP application server on the same system) on the Primary server from the SAP CDs as described in the SAP installation guide with the R3Setup program. Name the SAP system TS1 and use 00 as system number. Before running R3Setup modify

the file DBSIZE.TPL in the installation directory as follows: replace

PSAPTEMP=0;0;32;4;@Z_SAPDATAPATH=SAPDATAT@

with

PSAPTEMP=1800;1;8;4;@Z_SAPDATAPATH=SAPDATA7@

This change will cause the temporary tablespace PSAPTEMP to be created as a DMS tablespace with one container in /db2/TS1/sapdata7. By default, an SMS tablespace is created.

The R3Setup program will create the DB2 instance db2ts1 and the database TS1. It will also update the database configuration to set the log path to
