Creating Target Directory Paths

Question

My questions are mixed in below, marked with "Q:"
Task 7A-1-6 in the PTools 8.48 Installation Guide talks about directory path structures that are required by the Oracle DBMS install wizard, but need to be manually created by me.
I installed database 10g. My SID is "HCM". There is an initHCM.ora file in my database folder. The contents were:
SPFILE='C:\oracle\product\10.2.0\db_1/dbs/spfileHCM.ora'
and I added the following, per install guide instructions:
DB_NAME = HCM
DB_FILES = 1021
CONTROL_FILES = (/filesystem1/cntrl1HCM,/filesystem2/cntrl2HCM)
OPEN_CURSORS = 255
db_block_size = 8192
remote_login_passwordfile=NONE
Q: I substituted HCM for <SID> in the CONTROL_FILES variable, but are things like filesystem1 and filesystem2 meant to be literals, or is it intended that I substitute something for these? Also, there are some forward slashes in the SPFILE variable - is that ok for Windows?
The guide mentions these CREATEDB.SQL references...
startup nomount pfile=%ORACLE_HOME%\database\init<SID>.ora
DATAFILE '<drive>:\oradata\<SID>\system01.dbf' SIZE 400M
LOGFILE '<drive>:\oradata\<SID>\log01.dbf' SIZE 70M,
'<drive>:\oradata\<SID>\log02.dbf' SIZE 70M;
*...So I assume that I need to create c:\oradata\HCM*
The guide then says:
The init<SID>.ora parameter file that is referenced in the CREATEDB.SQL script makes the following
directory path structure references:
Note. Portions of the init<SID>.ora parameter file have been omitted for clarity. These paths are hardcoded
by the user creating the init<SID>.ora parameter file. The Data Configuration Wizard will not make any
substitutions for mount point, target directory path, or <SID> in the init<SID>.ora file.

Control file references:
+
control_files = ("c:\apps\db\oracle9i\oradata\ORC1\control01.ctl", "c:\apps\db⇒
\oracle9i\oradata\ORC1\control02.ctl", "c:\apps\db\oracle9i\oradata\ORC1⇒
\control03.ctl")
background_dump_dest = c:\apps\db\Oracle9i\admin\ORC1\bdump
core_dump_dest = c:\apps\db\Oracle9i\admin\ORC1\cdump
user_dump_dest = c:\apps\db\Oracle9i\admin\ORC1\udump
Q:  Does this mean I need to create c:\apps\db\Oracle10g\admin\ORC1 plus subfolders bdump, cdump and udump?  I particularly wonder if those exact names are correct, especially since the examples are for the 9i version.
Q:  The guide says (above) that it's the init<SID>.ora parameter file which makes the above control file references... but as I showed above, that file only contained the one line, before I added the parms I mentioned.  Is the install guide saying that I should add the control file references above to my initHCM.ora file?

Answer 1

With regard to the CONTROL_FILES variable...
I'm not sure how forward slashes are meant to be interpreted in the Windows world. Are you saying that I should substititute an entire valid Widows path, like this?
CONTROL_FILES = (c:\myfilesys1\cntrl1HCM.txt,c:\myfilesys2\cntrl2HCM.txt)
...after having first created folders c:\myfilesys1 and c:\myfilesys2, and that the database creation script will generate files cntrl1HCM.txt (I added the extension) and cntrl2HCM.txt?
Can you post a sample Windows init<SID>.ora file?

...on re-reading, it seems to me that section Task 7A-1-5: Creating an INIT<SID>.ORA File shows the general format:
CONTROL_FILES = (/filesystem1/cntrl1<SID>,/filesystem2/cntrl2<SID>)
...but section Task 7A-1-6: Creating Target Directory Paths shows an example of substituted code for this line:
control_files = ("c:\apps\db\oracle9i\oradata\ORC1control01.ctl", "c:\apps\db\oracle9i\oradata\ORC1control02.ctl", "c:\apps\db\oracle9i\oradata\ORC1\control03.ctl")
Is that true? i.e. does this mean that I can create any path and file name I want, and the database create script will read it here and use it?
If so, does this mean that I have to substitute actual paths ANYWHERE I see a forward slash?
Also... I'm thinking that ORC1 in the sample code is their example of the SID, and for me it might be HCM instead.
I note that their example shows three control files instead of the two shown in the first template. Does it matter.
Q: Are these control files files that will be written by the create script, or are they a reference to files I should have created and populated?
