Exadata ORACLE_HOME question
Hi,
I would like to know if there is a best practice regarding ORACLE_HOME in exadata machine.
If we are going to have 3 databases on quarter rack machine.
one databse is going to use as staging database.
The second is going to use as reporting database
the thread one is going to be use as repository.
Question one:
============
I would like to get your advice if i should have only one ORACLE_HOME for all the 3 the rdbms
or having ORACLE_HOME for each one of them.
Question Two:
============
Regarding the ASM disk groups , should i have only one disk group named DATA for example , or having for each database its own diskgroup
Best Regards
Hi Yoav,
should I have only one ORACLE_HOME for all the 3 the rdbms
or having ORACLE_HOME for each one of them?Use one ORACLE_HOME for your dbses. Just keep it simple.
BTW Current Exadata deliveries by ACS have the following oracle homes.
/u01/app/11.2.0.3/grid
/u01/app/oracle/product/11.2.0.3/dbhome_1..
Should i have only one disk group named DATA for example
or having for each database its own diskgroup?By default ACS will create the DATA, RECO and DBFS_DG disk groups just put you datafiles in DATA and use IORM to control resource usage
between databases.
Regards

Is there a way to create different diskgroups in exadata?
We have a need to have some other diskgroups other than +DATA and +RECO.
How do we do that? Exadata version is x3.
Thanksuser569151 -
As 1188454 states this can be done. I would first ask why is it you need to create additional disk groups than the data, reco and dbfs disk group created by default? I often see Exadata users question the default disk groups and want to add more or change the disk groups to follow what they've previously done on non-Exadata RAC/ASM environments. However, usually the data and reco disk groups are sufficient and allow for the best flexibility, growth and performance. One reason to create multiple disk groups could be for wanting to have different two different redundancy options for a data disk group - to have a prod database on high redundancy and a test database on normal redundancy for example; but there aren't a lot of needs to change it.
To add disk groups you will need to also re-organize and add new grid disks. You should keep the grid disk prefix and corresponding disk group names equivalent. Keep in mind that all of the Exadata storage is allocated to the existing grid disks and disk groups - and this is needed to keep the necessary balanced configuration and maximize performance. So adding and resizing the grid disks and disk groups is not a trivial task if you already have running DB environments on the Exadata, and especially if you do not have sufficient free space in Data and Reco to allow dropping all the grid disks in a failgroup - because that would require removing data before doing the addition and resize of the grid disks. I've also encountered problems with resizing grid disks that end up forcing you to move data off the disks - even if you think you have enough space to aloo dropping an entire fail group.
Be sure to accurately estimate the size of the disk groups - factoring in the redundancy, fail groups and reserving space to handle cell failure - as well as the anticipated growth of data on the disk groups. Because if you run out of space in a disk group you will need to either go through the process again of resizing all the grid disks and disk groups accordingly - or purchase an Exadata storage expansion or additional Exadata racks. This is one of the reasons why it is often best to stick with just the existing Data and Reco.
To add new grid disks and disk groups and resize the others become very familiar with the information in and follow the steps given in the the "Resizing Storage Griddisks" section of Ch. 7 of the Exadata Machine Owner's guide as well as the information and examples in MOS Note: "Resizing Grid Disks in Exadata: Examples (Doc ID 1467056.1)". I also often like to refer to MOS note "How to Add Exadata Storage Servers Using 3 TB Disks to an Existing Database Machine (Doc ID 1476336.1)" when doing grid disk addition or resize operations. The use case may not match but many steps given in this note are helpful as is discusses adding new grid disks and even discusses creating a new disk group for occasions when you have cell disks of different sizes.
Also, be sure you stay true to the Exadata best practices for the storage as documented in "Oracle Exadata Best Practices (Doc ID 757552.1)". For example, the total number of griddisks per storage server for a given prefix name (e.g: DATA) should match across all storage servers where the given prefix name exists. Also, to maximize performance you should have each grid disk prefix, and corresponding disk group, spread evenly across each storage cell. You'll also want to maintain the fail group integrity, separating fail groups by storage cell allowing the loss of cell without losing data.
Hope that helps. Good luck!

Hi Friends
I'm running oracle 11.2.0.3.0 on windows environment.
We need to change our server that has began too old to attend our needs
We're planning to run a SSD raid 5 for improve performance. Even though raid 5 is not the best solution for HDDs, it would be faster enough to even perform better than 8 HDDs on raid 10.
Do you guys already run Oracle over SSDs RAID ?
What about the performance on writting?
What about the lifecycle of SSDs that are quite less than HDDs? I've heard from the vender that its about 6 years....
Can we share experiences on that?
Tks a lotIn my opinion, it is still a bleeding-edge technology. For my purposes, I avoid bleeding edge. Your purposes may be different. But you see, asking who's using it in production doesn't get much actual response. You have some amount of control over how interesting are the times you live in. The danger lies in making decisions based on what the vendors are selling, rather than your database needs. I can't see that much changes over a year, certainly in not how Oracle writes redo (although it has changed for exadata, the question becomes how long until the ability to [url http://structureddata.org/2011/10/12/exadata-smart-flash-logging-explained/]parallel write and only care about the fastest device is allowed to the rest of the world). I think it is hard to predict whether the self-tuning aspects of Oracle will handle these oddly fast devices appropriately, and if there are issues there, there could be some lag time before enough people complain that Oracle deals with it. Of course, they may be way ahead of me there, they aren't going to be completely reactive with a new version coming out, perhaps the developers got to play with new toys.
The EMC device someone mentioned sounds pretty cool, although I still have bitter memories of HP Autoraid moving stuff around inappropriately.
Of course the space shuttle was cool too. Note that the US is now dependent on big dumb Russian rockets. -
Simple misc. questions re unix password,upgrade options and $ORACLE_HOME
Hi,
Some very basic questions
1: If i change my oracle user's UNIX password, do other things depend up on this? I know that OracleEM asks for it once in a while, but am unsure if anything else cares.
2: In the Universal installer : There is an option to "get software updates via the universal installer" - does that just mean it downloads things like the CPU sets and the like and helps you install them or does it just sign you up for notifications?
3: I recently upgraded from 11.2.0.1 to 11.2.0.3 thus creating a new db_home
Old dir was : /u00/app/oracle/product/11.2.0/
new one is : /u00/app/oracle/product/11.2.0.3/
Can I now delete the old one?steelnwool wrote:

Yes you can change anytime anywhere :) no issue on running database.
2: In the Universal installer : There is an option to "get software updates via the universal installer" - does that just mean it downloads things like the CPU sets and the like and helps you install them or does it just sign you up for notifications? Notification which will suggest you to install security patches according to your release.

If you are already using 11.2.0.3 then there is no harm in removing old oracle_home. The better way to remove oracle_home is through Universal Installer, click on remove oracle_home, this will aumatically remove oracle_home you choosed.
Can I now delete the old one?Also see-http://docs.oracle.com/cd/B28359_01/install.111/b32002/remove_oracle_sw.htm -
Hi,
I want to know, exadata database machine is based on SUN hardware or HP hardware?
I see that HP has exclusivity of this technology:
From HP:
http://www.hp.com/hpinfo/newsroom/press/2008/080924xa.html
HP today announced that it is the exclusive systems and integration technology provider for the Oracle® Exadata Storage Server.
From SUN:
http://www.oracle.com/database/exadata.html
Oracle Exadata Storage Servers combine smart storage software from Oracle and industry-standard hardware from Sun to deliver the industry's highest database storage performance
Thank youExadata 1 was HP
Exadata 2 is Sun. -
Question regarding Listener and Server Processes in dedicated server mode
Good morning,
The Oracle documentation states that when a client connection request is received on the server, the Listener creates a Server Process which will work with the database instance to carry out the tasks requested by the user/client process. So far, everything good.
Now, when the user is at the Oracle server itself, the Listener does not need to be running to establish a connection to the database. It is therefore possible to stop the Listener and still connect using sqlplus and a valid username and password.
In the above case, the question is: if the Listener is not running, what/who created the Server Process that communicates with the database instance on behalf of the user ? Stated a different way, in the normal case, the Listener would get the request and create the server process. When the Listener is not running what part of Oracle gets the requests and creates the server process ?
Clarification on how this case is handled is much appreciated, thank you,
John.When using bequeath protocol the server process is created by the client process: it's the client process that is using ORACLE_SID and ORACLE_HOME to compute shared memory key (under UNIX) to know which SGA to attach (i.e. which instance to connect to):
Example with SQL*Plus :

If the client and database exist on the same computer, then a client connection can be passed directly to a dedicated server process without going through the listener. This is known as a bequeath protocol. The application initiating the session spawns a dedicated server process for the connection request. This happens automatically if the application used to start the database is on the same computer as the database.

Can you help me?
Thank you,
Regards,Hello 976232,
This type of issue would definitely be Oracle Support territory, so I'd be definitely checking in with them. A few clarifying questions you can expect to be asked:
- What is the impact on your system because of this error message
- How often does it happen
- Can you trigger it on demand?

EBS upgrade from 11i to R12 using Maintenance Wizard question
I have installed Maintenance Wizard in development envrionment. I picked module to upgrade 11i to R12. When I am defining the node it not only picked up 11i nodes but required me to configure R12 nodes. So Do I have to to create upgrade file system(for R12) and then configured R12 nodes in Define nodes? My configuration is in In configuration at this time as I did not configured R12 nodes.
Please help me resolve this issue.My question is which database oracle_home we have to consider to upgrade R12? and What about another one oracle_home?
When you run Rapid Install, provide the details of the already upgraded/installed 11.2.0.3 ORACLE_HOME.
For 11gR1 ORACLE_HOME which is installed by Rapid Install, please see (How to upgrade Oracle E-Business Suite from 11i to 12.1.1 and keep the existing 10g Database? (Doc ID 1345020.1)).
Thanks,

Oracle 9.2.0.3.0 patch set for windows - questions
Hi!
I have for that some questions. I have oracle 9.2.0.1.0 on a windows 2003 server running with one local database - no real apllication cluster.
I don't understand which instructions I have to make for oracle upgrade?
Must I also make the 3. instruction? Connect to databse prior and drop?
Must I also make the post install action for my database?
(startup migrate ...)
what means at post install actions the following:
'execute these post install actions only if you have one or more databases associated to the upgraded $oracle_homee.
My database path is e:\oracle\oradata\database my oracle path is e:\oracle\ora92 have I in my case make the post install actions?
Thanks for help!
1. When applying this patchset on Windows NT, XP or Windows 2000, you must log onto the system as a user with Administrative privileges
(e.g. as a user which is a member of the local Administrators group).
2. Unzip the downloaded patch set file into a new directory.
3. Drop the xmlconcat function by running the following commands:
drop public synonym xmlconcat;
drop function xmlconcat;
4. Shut down any existing Oracle Server instances in the ORACLE_HOME to be patched with normal or immediate priority. i.e.: Shutdown all instances (cleanly). Stop the database services, and stop all listener, agent and other Oracle processes running in or against the ORACLE_HOME to be installed into.
5. Perform the following pre-install steps for Real Application Clusters (RAC) enviroments only:
IN ADDITION TO STOPPING ALL ORACLE SERVICES IN THE ORACLE_HOME TO BE UPGRADED:
If you are running in a RAC enviroment, stop the following Windows service(s)/devices(s) using the Net Stop command:
Stop the Windows service named "OracleGSDService"
Stop the Windows service named "OracleCMService9i".
Stop the Windows device named "OraFenceService" (This Device does NOT show up as a Service in the Control Panel).
For Example:
C:\>net stop OracleGSDService
C:\>net stop OracleCMService9i
C:\>net stop OraFenceService
Once the above steps have been performed on all the nodes of the cluster, you should then be able to upgrade the OSD components to the 9.2.0.3 versions. This can be accomplished by...
xcopy all the files in the \Disk1\preinstall_rac\osd\*.* directory to the directory in which the OSD components were originally installed on all nodes(typically %SystemRoot%\system32\osd9i).
Note: You may also be able to look in HKEY_LOCAL_MACHINE\Software\Oracle\OSD9i registry key to determine the directory in which the original OSD components were installed. Now the OSD components can be restarted on all the nodes in the cluster.
C:\>net start OraFenceService
C:\>net start OracleCMService9i
C:\>net start OracleGSDService
After all of the above steps have been completed on all the nodes of the cluster, you are now ready to proceed with the Oracle 9.2.0.3.0 patchset installation.
6. Start the installer:
If the current Installer version is less than 2.2.0.18.0 then download the Installer 2.2.0.18.0 from Oracle Metalink where it can be accessed with the bug number 2878462 and choosing the MS Windows NT/2000 Server platform, then run the setup.exe 2.2.0.18.0 from the C:\Program Files\Oracle\oui\install directory .
7. You may install the Patch Set through either an interactive or a silent installation.
To perform an interactive installation using the Oracle Universal Installer graphical interface:
1. Start the installer from the newly installed OUI 2.2.0.18.0 by running the version of setup.exe located at C:\Program Files\Oracle\oui\install and verify
that the version of the OUI GUI is 2.2.0.18.0 before proceeding.
2. Follow the steps given below within the installer:
1. On the Welcome screen, click the Next button. This will display the File Locations screen.
2. Click the Browse button for the Source... entry field and navigate to the stage directory where you unpacked
the Patch Set tar file.
3. Select the products.jar file. Click the Next button
The products file will be read and the installer will load the product definitions.
The products to be loaded will be displayed (verify ORACLE_HOME setting for this first).
4. Verify the products listed and then click on the Install button.
5. Once the installation has completed successfully, it will display End of Installation. Click on Exit and confirm
to exit the installer.
To perform a silent installation requiring no user intervention:
1. Copy the response file template provided in the response directory where you unpacked the Patch
Set tar file.
2. Edit the values for all fields labeled as "<Value Required>" according to the comments and examples
in the template.
3. From the unzipped patchset installation area, start the installer by running the setup executable passing
as the last argument the full path of the response file template you have edited locally with your own
value of ORACLE_HOME and FROM_LOCATION:
setup.exe -silent -responseFile <full_path_to_your_response_file>
Post Install Actions
Execute these "Post Install Actions" only if you have one or more databases associated to the upgraded $ORACLE_HOME.
Important Notes
1: Java VM and XML DB Requirements
Users who have JVM (Java enabled) or JVM and XDB installed on their 9.2.0.1 databases should make sure that the init.ora parameters shared_pool_size and java_pool_size are each 150 MB or more before running the catpatch.sql upgrade script. Failure to do so could result in an unrecoverable memory failure during running of the script. Please note that JVM and XML DB was shipped as part of the default 9.2.0.1 seed database and will be present unless the user explicitly installed a 9.2.0.1 instance without them.
2: SYSTEM table space
If you have JServer installed in the database, you should check to be sure there is at least 10M of free space in the SYSTEM table space before running these actions.
3: Installing on Cluster Databases
If you are applying this patch set to a cluster database, then set the CLUSTER_DATABASE initialization parameter to false. After the post-install actions are completed, you must set this initialization parameter back to true.
To complete the installation of this patch set, you need to start up each database associated with the upgraded $ORACLE_HOME, start the database listener (e.g., lsnrctl start), login using SQL*Plus (e.g., sqlplus "/ as sysdba"), and run the following commands/scripts in order from $ORACLE_HOME within a MIGRATE session. If you are using the OLAP option, make sure that the database listener is up.
startup migrate
spool patch.log
@rdbms/admin/catpatch.sql
spool off
Review the patch.log file for errors and re-run the catpatch script after correcting any problems
shutdown
startup
This step is optional - it will recompile all invalid PL/SQL packages now rather than when accessed for the first time - you can also use utlrcmp.sql to parallelize this in multiprocessor machines:
@rdbms/admin/utlrp.sql
Execute the following if you use Oracle OLAP option:
alter user olapsys identified by <password> account unlock
connect olapsys/<password>
@cwmlite/admin/cwm2awmd.sql
exit
Execute the following script only if you have version 9.2.0.1.0 of Oracle Internet Directory installed in your ORACLE_HOME. Make sure that the database and database listener are running and that all parameters are specified prior to running the script:
$ORACLE_HOME/bin/oidpatchca.bat
-connect <Connect String>
-lsnrport <Listener Port>
-systempwd <SYSTEM Password>
-odspwd <ODS Password>
-sudn <Super-User DN>
-supwd <Super-User Password>
-dippwd <Password to register DIP Server>
Where:
connect - Database connect string
lsnrport - Database Listener port
systempwd - Password of the database 'SYSTEM' user
odspwd - Password of the database 'ODS' user
sudn - Super-user DN
supwd - Super-user Password
dippwd - New password to register Directory Integration Server. This password must conform to the password policy in the OID server
Execute the following steps only is you are using the RMAN catalog.:
rman catalog <user/passwd@alias>
upgrade catalog;
upgrade catalog;I don't understand which instructions I have to make for oracle upgrade?
-- You have to follow all the instructions mentioned
(Just check for few if's for Cluster enabled, OID and OLAP databases. Perform these steps only if they apply)
Must I also make the 3. instruction? Connect to databse prior and drop?
-- Yes you should do
Must I also make the post install action for my database?
(startup migrate ...)
-- Yes. Do run catpatch.sql .
what means at post install actions the following:
'execute these post install actions only if you have one or more databases associated to the upgraded $oracle_homee.
-- In this step make sure you do step 1
1: Java VM and XML DB Requirements
Otherwise catpatch.sql will fail.
Do 2 and 3 only if applicable

O/S: Sun Sparc Solaris 64 bit 5.10
3rd Party Clusterware - Veritas Storage Foundation for RAC (SFRAC) 5.0 MP3
CRS: 10.2.0.4
CRS is owned by oracle:dba (with the exception of anything owned by root)
9iR2 (9.2.0.8) RAC RDBMS ORACLE_HOME is owned by oraofsg:dba
9iR2 (9.2.0.8) RAC Database Name: ofsg
10gR2 (10.2.0.4) RAC RDBMS ORACLE_HOME is owned by oracle:dba
Metalink note 220970.1
Misc. Info:
Action: /var/opt/oracle/srvConfig.loc was renamed after 9i database and GSD stopped prior to installing CRS.
Why?: 10g CRS chose to use 9i's srvm.dbf rather than the file system I had created for the 10g CRS cluster registry.
Task at Hand:
Need to register 9.2.0.8 RAC database ofsg under 10gR2 CRS.
Issue:
As 9i RAC database owner oraofsg with the 9i RAC environment set, and 9i GSD down:
srvctl add database -d oraofsg -o /sv01/sw/oraofsg/ofsgdb/9.2.0
PRKR-1005 : adding of cluster database ofsg configuration failed, PROC-5: User does not have permission to perform a cluster registry operation on this key. Authentication error [User [oraofsg] does not match with initialized user] [0]
Question: Has anyone successfully registered a 9i RAC database under 10g CRS?
Thanks for your consideration.
Regards,
JerryHi
CRS_HOME must be owned by a different user:group (preferably root) than $ORACLE_HOME (owned by oracle), for several reasons like patching.
Please note also that you will need an ASM dedicated home and also a AGENT_HOME that can be owned by oracle.
Hope this helps. -
Multiple Oracle_home (best way to upgrade) ??
hello all,
I was going thru the below link and found this very cool trick that i didnt know.
http://searchoracle.techtarget.com/tip/0,289483,sid41_gci1252556,00.html?track=NL-93&ad=587723&asrc=EM_NLT_1354356
it goes something like this
*My favorite best practice is the one about multiple Oracle Homes. Here it how it goes. When applying a patch or a patchset, I recommend against applying to the existing Oracle Home. Instead, I suggest creating a new Oracle Home, and apply the patches there.
I create the first Oracle Home at /app/oracle/db_1, for instance. When a patch comes out, I install the whole Oracle software in a different home -- /app/oracle/db_2 -- and then apply the patch there. During the process of installation and patch application, the database is up and running, as it runs off the home /db_1. When the outage window comes, all I have to do is to shut down Oracle; change Oracle Home to db_2 and bring the database up. If there is a problem, I can reset the Oracle Home back to the old one.
So, here is the conventional approach:
1. Shut down the database
2. Apply patch to the Oracle Home
3. Start the database
4. In case of problems:
5. Shut down the database
6. Roll back the patch
7. Start the database
Steps 2 and 6 could take as much as three hours depending on the amount of patching. The database is down during these times.
In the new approach:
1. Install new Oracle Home
2. Apply the patch to the new Home
3. Shut down the database
4. Change Oracle Home to the new location
5. Start the database
6. In case of problems:
7. Shut down the database
8. Change Oracle Home to the old one
9. Start the database
The database is down only during steps 4 and 8, which takes a couple of minutes at the most, not hours.*
But my question comes here...first of all is it possible ?? i am sure it is becoz Arup Nanda one of the know oracle guys wrote this article. so here are my Q?
1- So if i get this right...if i want to upgrade to 11g...and my database is on 10g...all i need to do this create a new 11g home...shutdown my 10g database...set my oracle_home to 11g and start my database up...and its all upgraded ????
2- Another thing that worries me is how this might behave in RAC environment. Any idea
on that? i know RAC provides the rollover upgrade so we might
not need this. but would be cool to know how it behaves...ANY IDEAS ?
3- Also, I wonder how CRS and ASM home like this idea ??Basically when you switch from the old home to the new Oracle home you are following manual database upgrade procedures so you would need to run whatever scripts are contained in the instructions. Normally for an upgrade that is catalog and catproc and you would run these immediately after bringing the database up on the new home. For a patch there might be an upgrade script or no database level scripts may be necessary. That is the patch may effect only the binary.
What we actually do is in test install new copy of existing Oracle then patch/upgrade to current level. Next build an empty database and populate it. Next test. When OK shut it down and apply patch. Startup and follow Readme or Upgrade manual procedures. If test works fine and the upgrades tests OK then we remove the new test db, switch the actual in-use test databases over to the new patched home, run upgrade scripts as necessary, and continue.
After a few weeks we start getting maintenance windows to do production. Since we have multiple databases we usually do not do all of them at once.

Listener configuration and other questions
I have installed 2 database instances on the same database and under the same database home.
The instances use the same listener. If i try to start enterprise manager in browser for both instances,
the Enterprise Manager starts just for the last installed instance. I have edited the listener.ora file an
added one more Description with another port number like folowing:
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = fusion)(PORT = 1522))
to the following content:
LISTENER_APPDB =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = fusion)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
now the file looks like following:
LISTENER_APPDB =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = fusion)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = fusion)(PORT = 1522))
ADR_BASE_LISTENER_APPDB = D:\app\oracle2
SID_LIST_LISTENER_APPDB =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\app\oracle2\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\app\oracle2\product\11.2.0\dbhome_1\bin\oraclr11.dll")
i have also changed the port of one of the instances in the tnsnames.ora file from 1521 to 1522.
Now it is possible to start Enterprise Manager for both instances. But after i connect to one of the
instances with the Enterprise Manager the other instance logs of. Is it ok so??? Will i have problems
with this configuration?? Should i do something different??
Second question: After i have installed an instance, during the installation some patches where
automaticaly installed. After that i have installed another instance. Do i have to patch this instance too???
Are the patches installed for the whole DBMS or just for one instance???
*Third question: If i have 2 instances how can i set the parameter btree_bitmap_plans for only*
one of the instances ??? I have found the following code to do this:
ALTER SYSTEM SET "_b_tree_bitmap_plans"=false SCOPE=SPFILE;
but for wich instance the parameter will be set for both or just for one? Do i have to choose
one of the instances?? How can i do that??

Good afternoon,
In the 2 Day DBA document it states:
>
When you invoke DBCA as part of the Oracle Database installation process, DBCA
creates a password file with one entry: the SYS user.
>
I created the database using DBCA and, it must have created a password file for me since I am able to log in remotely to the database.
The question is: I cannot locate the password file DBCA created, I don't know what its name is. Can someone provide me with the name DBCA uses for the password file ?
Thank you very much for helping,
John.Hello SB,

I don't know if this qualifies as "proof" but... from the 2 Day DBA document distributed by Oracle, page 6-9:
>
When you invoke DBCA as part of the Oracle Database installation process, DBCA
creates a password file with one entry: the SYS user. Granting SYSDBA to a user adds
that user to the password file automatically.

I have no reason to doubt that statement. ;)

for some/many/most Oracle versions which you decided we did not need to know yours the file resides in
$ORACLE_HOME/dbs

I didn't decide you didn't need to know. I forgot to mention I am using Windows. As far as the Oracle version, since I used to constantly forget, I made the version part of my user name 11gR2, I can see how that can be easily overlooked.
Thank you for your help,
John.
