Migrating SAP ERP 6.0 and IBM DB2 LUW version 9.1 from Solaris

10 Enterprise on Sun Fire T2000 to Red Hat Enterprise Linux

Advanced Platform for SAP applications on IBM System x3650 M2

with Intel Xeon processor

Appendix B. Methodology: Preparing the system for SAP ERP 6.0

1. Ping the host name for the server, and verify that the IP

address is not the loopback address (127.0.0.1). If it is, edit

the /etc/hosts file, and set it to the correct IP address.

2. If you are installing the SAP software on a pre-configured

system, you may need to increase the swap size. Because

the disk is already partitioned in this case, use the following

commands to create the swap file:

dd if=/dev/zero of=/swapfile bs=1K count=66560000

mkswap /swapfile

swapon /swapfile

NOTES: As we mentioned earlier, the exact amount of swap

space will depend on the SAP components you install.

If you want, you can use the swapoff command to turn off

the swap file partition.

 Edit /etc/fstab.

 Add the following line:

/swapfile none swap defaults 0 0

 Use swapon –s to verify the swap is active.

3. Edit the file /etc/profile, and add the following line:

CPIC_MAX_CONV=200; export CPIC_MAX_CONV

4. Set hard and soft nofile in /etc/security/limits.conf by

adding the following lines:

@sapsys hard nofile 32800

@sapsys soft nofile 32800

@dba hard nofile 32800

@dba soft nofile 32800

5. Verify that /etc/sysctl.conf, contains the following lines:

kernel.msgmni=1024

kernel.sem=1250 256000 100 1024

vm.max_map_count=1000000

kernel.shmmax=23136829430

kernel.shmall=5242880

6. Reboot to make all the settings active.

7. If you plan on using remote desktop software, you may also

complete the following two optional steps:

a) Set Red Hat using SystemPreferencesRemote

desktop.

b) Set PS1= <string>to set prompt.
