[OBIEE11g] Error: CREATING ASInstance failed

Cause: This is because of an invalid host file.

Guys please note that a static ip is needed for the OBIEE instance creation and thus installation.

Resolution:

    The usual entries in the host file is as below”

121. 0. 0.1 localhost (default)

Change this to

The actual physical IP of the machine (set using the lookback adapter)

192.168.31.xxx sandeep-pc

It can be of the any no routable IP given below:

10.10.10.10

    or

    192.168.1.XXX (0-255)

DO NOT END the installation if this fails in this step . But make sure the host files are as below     and validate them

• ping sandeep-pc (it should return the IP entered in the host file).
• Please check ur TNSNAMES.ORA and LISTNER.ORA files and replace ‘localhost’ with the host name (sandeep-pc).
• Go to the LSNECTL.EXE from the ORACLE_HOME dir and run LSNRCTL.EXE as administrator (in win 7).
  execute the following:
  >LSNRCTL stop
  >LSNRCTL reload
  >LSNRCTL start
  Open a new command prompt and execute the following:
  c:\ tnsping orcl
  also verify the following:
  nslookup sandeep-pc
  nslookup 192.168.1.xxx
  Go back to the installation and click RETRY. the installation should go through.
  If it do not go through then quit the installation and clear the registries and do an new install in a new FMW home
