10gR2 under Solaris 10: Error creating sample database

Question

I am attempting to install 10gR2 on a Sun Ultra 10 Sparc workstation running Solaris 10. I successfully configured the ASM drives and loaded the software, and am now attempting to install the actual database software.
While the installer is running the Database Configuration Assistant, the second "recommended" configuration program, I get an error almost halfway through that says "ORA-19879: error reading backup piece". Looking through the logs kept by the Assistant, I find this entry:
Grant succeeded.

old 30: dbms_backup_restore.restoreDataFileTo(data_file_id,'&data_file_name');

old 33: dbms_backup_restore.restoreBackupPiece('&data_file_backup', done);
new 33: dbms_backup_restore.restoreBackupPiece('change_on_install', done);

I couldn't find anything wrong in "example.dmp", and I couldn't find "change_on_install" in the directory listed, even while the error window was still on the screen. Most of the errors in the log following this fragment have to do with tablespace EXAMPLE not being there.
Someone else with a similar problem solved it by installing the database software without the sample databases. I'll give that a try tomorrow, but I'd still like to know where I'm even supposed to look to find the problem I had above.
Thanks,

Answer 1

Okay, I've found at least one source for this problem. There is a script called mkplug.sql in the demo/schema directory that had a line that began "host imp .....". 'imp' is in the db_1/bin directory, which the PATH variable does not yet point to.
So, my question now is whether I should change "host imp..." to "host $ORACLE_HOME/bin/imp..." in all the files it appears in (sted_mkplug.sql and sdoepsgv.sql, as well as mkplug.sql), or add $ORACLE_HOME/bin to the PATH variable manually.
What I'm going to try is to deinstall the database, scrap the directories, then reload the software only. After that, I'll edit the files in the demo directory and use dbca to create the demo directories.
