Installation of the second SAP system on the same host on Unix
I have to install the second SAP System with Oracle on the same host on Solaris.
Which settings regarding following three points should I meet:
<b>1) oracle software</b>
- do I have here the choice or must I install the second DB software
<b>2) TNS Listener</b>
- which options are possible? two TNS Listener or one TNS Listener with two entries
- should I apply the other port during the SAPINST
<b>3) environment variables, authorizations, users</b>
ORACLE_HOME, ORACLE_SID, SAPDATA_HOME under which account (ora<sid>, <sid>adm)
Thank you very much!
