Naming conventions SID must be of three characters
First Char: G for GPIL
Second Char: R for R/3 and B for BIW installation. Third Char: D for Development, T for Test and P for Production e.g.
GRD: GPIL R/3 Development server
GRT: GPIL R/3 Test server
GRP: GPIL R/3 Production server
GBP: GPIL BIW production server
Requirement for AIX
Check tape drive #tar -cvf /dev/<tape_device> ./testfile
Check CD/DVD iso 9600 compatible #mount /cdrom
Disk checking #lspv
Checking free space #lspv - p <disk_name>
Checking installed RAM #lsattr -El sys0 -a realmem
Check CPU #lsconf
lsconf provides you detailed server info.
Check cpu hardware capability Verify hardware compatibility 32/64 bit #bootinfo -y
Software check C++ environment check #lslpp -L xlC.aix50.rte
OS version #lslpp -l bos.rte
Check required OS packages #lslpp -l | grep bos.rte, bos.adt, bos.adt.Base, bos.perf
Swap space Required swap space is 20GB #lsps -a or #lsconf | grep Page
Check NFS #ps -aef | grep nfs

Setting up file system
Procedure for creating file system Refer the file Creating file system in IBM AIX
CreatingFileSysteminAIX.doc
Create following file system Refer the file: GPI File systems.doc
Change permission of /oracle/<SID>/920_64 to 777 #chmod 777 /oracle/<SID>920_64
Exporting transport directory
Staring
NFS #smit >>communication and application and services
>>NFS >> network file systems >> configure NFS on this
sysetm
>> start NFS
Exporting
directory: /sapmnt #smit >>communication and application and
services >>NFS >> network file systems >> Add
directory to export list
enter the path of the directory which you want to export e.g. /sapmnt
choose export mode: read/write
In line host: allowed root access
enter the name of host the additional instance run
Export directory now, system restart or both: enter both
Mounting
/sapmnt at client Create mount points at the host on which
additional instance run #/usr/bin/mkdir <SAPMNT>/<SAPSID>exe
#smit >>communication and application and services
>>NFS >> network file systems >>Add file system for mounting
enter the path name of mount point
enter the path of remote mount directory
enter the host where remote directory resides
set mount now, add entry to /etc/filesystems or both: set both
set /etc/filesystems entry will mount the directory on system restart to yes
change mount file system soft or hard to soft
#mount -v nfs gpisaps2:/sapmnt /sapmnt
Manually vi /etc/exports add following line
/sapmnt -deleg=yes,sec=sys:krb5p:krb5i:krb5:dh:none,rw
save it now #exportfs -a
