Error when start sqlplus or svrmgrl under 817

There are error messages below when started sqlplus and svrmgrl under 8.1.7. Also why it started 'Oracle9i Enterprise Edition Release 9.2.0.1.0 ' when I issued svrmgrl under 8.1.7?

1. SQLPLUS>

your environment is screwed, sort out ORACLE_HOME, ORACLE_SID, NLS_LANG and such like

Could you give more details on how? It is HP server and running 9.2.0.6 and 8.1.7.

which oraenv

The default ORACLE_HOME is 9.2.0.6

source oraenv or coraenv (depending on shell) to setup correct environment.

We are using Korn shells, I have checked oraenv in each /817 or /920 oracle bin directory, they are the default script, I am a newbie here, could you tell me where and how to change the environment to allow the new DB run on 817? Thanks.

ORACLE_SID=8.1.7
export ORACLE_SID

Set the above at the command prompt and try to start 8.1.7 and do the same for 9.2.0.6

need to do the oracle_home as well!

just do

. oraenv (note the dot)

then enter the name of the oracle sid when its asks you and you environment should then be set
