Installation of the second SAP system on the same host on Unix

Hello!

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!

regards

Thom

    use:

    2 ORACLE_HOME

    2 listeners with different ports

    different environment variables

    and different system number.

    1) You can install just ONE time the software. During patching both systems will need to be shut down, keep that in mind. It works but you will,, however, need to configure things manually (setting ORACLE_HOME during sapinst etc.)

    2) If you install the software once you will only run one listener.

    3)

    - use one group (sapsys) for both system

    - set /usr/sap group writable

    I suggest installing Oracle two times (do NOT copy but install a second time), it will make things MUCH easier.

    And do NOT do "chmod -Rf 777 /usr" 😉)
