Creating Directories

These directories are usually created as separate file systems. This depends entirely on your requirements. We choose to create them as simple directories, as they are all located on the same RAID 5 anyway:

First we will set owners and rights of some directories (as user root):

# chmod 775 /oracle
# chmod 777 /sapmnt
# chown root:dba /oracle
# chown sidadm:sapsys /compat/linux/usr/sap
# chmod 775 /compat/linux/usr/sap

Second we will create directories as user orasid. These will all be subdirectories of /oracle/SID:

# su - orasid
# cd /oracle/SID
# mkdir mirrlogA mirrlogB origlogA origlogB
# mkdir sapdata1 sapdata2 sapdata3 sapdata4 sapdata5 sapdata6
# mkdir saparch sapreorg
# exit

For the Oracle 8.1.7 installation some additional directories are needed:

# su - orasid
# cd /oracle
# mkdir 805_32
# mkdir client stage
# mkdir client/80x_32
# mkdir stage/817_32
# cd /oracle/SID
# mkdir 817_32

Note: The directory client/80x_32 is used with exactly this name. Do not replace the x with some number or anything.

In the third step we create directories as user sidadm:

# su - sidadm
# cd /usr/sap
# mkdir SID
# mkdir trans
# exit
