Intel(R) Embedded Server RAID Technology II and Oracle VM Server

Hi There
This is a head's up for anyone installing on a beast with the above mentioned on-board raid controller.
You have to use the Intel Setup CD to configure the raid. When you use the raid's bios to setup raid, the bios assign a name to the raid that confuse/brakes dmraid. I don't think you can set the raid's name in the bios. When you use the Intel CD you can configure the raid and you can edit the name of the raid. Pleas note, no spaces and no funny characters like #,%,@, in the raid name.
If you don't use the Intel CD, the bios/dmraid create a name that changes every time you reboot the server, I think this is due to spaces and the funny characters. So install will work but after the first reboot, dmraid won't find the raid and your raid configuration won't work.

Hi,
Thank you for the information. As you said from the behavior it seems that the build-in drivers of Windows Server Technical Preview will not work with the specific motherboard hence the RAID1 cannot work well.
I'll log the issue down.

Cactus and jars on (embedded) server

Hi
Has anyone tried the Cactus test frame work and got it to work? (when running the embedded oc4j server)
I keep getting noclassfound errors, no matter where I put the Cactus specific libararies. I have tried putting them in $JDEV_HOME/j2ee/home/lib and in $PROJ_HOME/public_html/WEB_INF/lib but to no success.
I have not tried to deploy the project to an external server, maybe that will work better...?
How about the differences of external and embedded server when it comes to where to put jars?
I find it difficult to understand how the embedded server works. Does the embedded server depend on any deployment profiles set up in the project?
Thanks for the help.

Has anyone tried the Cactus test frame work and got it to work? (when running the embedded oc4j server)I have not tried the Cactus test framework.
I keep getting noclassfound errors, no matter where I put the Cactus specific libararies. I have tried putting them in $JDEV_HOME/j2ee/home/lib and in $PROJ_HOME/public_html/WEB_INF/lib but to no success.For a document on OC4J classloaders, see
http://otn.oracle.com/oramag/oracle/02-sep/o52oc4j.html
Thanks for the redirection. That page explains a lot.
I have not tried to deploy the project to an external server, maybe that will work better...?It might, although the external server and embedded server use the exact same binaries. The problem you are having sounds like a configuration issue.Yes, it is a configuration issue. But the configuration may differ, as you say yourself.
How about the differences of external and embedded server when it comes to where to put jars?The configuration of the external and embedded servers are separate. So where you put jars depends on where the configuration is set up to look for jars. JDev automatically administers the embedded server config, and part of that is based on the external server config.I have not myself setup any library or classpath paths on the external server.
I find it difficult to understand how the embedded server works.Can you be more specific? Integrating J2EE server configuration with the features of an IDE like workspaces and projects is inherently complicated. What would help make it easier to understand how the embedded server works?What I meant is that it is difficult to understand the whole server configuration when running the embedded server. You say JDev automatically administers the embedded server config, and picks some configurations from the external server configuration, but how to know what yourself has to include in the external configuration...
Does the embedded server depend on any deployment profiles set up in the project?Only if you use project dependencies (Project Settings | Dependencies) to make a project depend on a deployment profile in a different project.Ok, this is clear.
Thanks for the help.You probably just need to define a Cactus libarary in your project and select the Cactus library as a project library. Then JDev will know to include the Cactus jars when running in the embedded server. Go to Project Settings | Libraries, define a new library, and add it to the project's list of selected libraries. This is exactly what I did.
With the new knowledge, by reading the j2ee classloader document, I hope I will straighten this out.
Thanks

Intel(R) ESB2 SATA RAID Controller not working out of the box

Dear all,
I'm using, for my tests, an old server with a supermicro X7DBN Server motherboard.
This motherboard comes with an embedded Intel(R) ESB2 SATA RAID Controller.
When I try a native installation from the technical preview DVD it sees the RAID1 volume that has been created (2 disk mirror) but when I select it to proceed with the installation there is an unknown error stating that it's impossible to write to this disk.
The same installation works perfectly with 2012R2 and the out of the box driver provided bin the install media.
An update from the previously installed 2012R2 to the Windows Server Technical Preview also works without problem.
It would make sens for MS to revert to the driver version embedded in 2012R2 for Intel(R) ESB2 SATA RAID Controller which is:
Name : Intel(R) ESB2 SATA RAID Controller
Date : 10.08.2010
Version : 8.6.2.1025
inf section : iaStor_Inst_RAID
Device ID : PCI\VEN_8086&DEV_2682&CC_0104

JDeveloper 11g is extremely slow when embedded server started

Oracle Jdev experts,
My machine configuration is - 2GB RAM, Intel Core2 Duo 2.4 GHz processor, 160GB HDD, Windows XP Professional
As such jdev itself runs on slower side as compared to other applications. Still it is manageable until I start embedded server.
After I start embedded server, my machine becomes terribly slow. I cannot open any other application..even opening notepad or blank browser window takes 5 min.
Available physical memory drops to less than 100MB which was around 1.4 GB before starting jdev. Please note that I had opened only jdev in the meantime.
Is there any way I can improve jdev performance and save significant time working on it?
Any suggestion in this regard is highly appreciated.
Thanks in advance

2GB, even though it may meet the "minimum" requirements is probably too low.

Css/js relative path for embedded server

We have recently begun using relative paths for css and js files in our deployed applications:
<link href="../../resources/css/global3.css" rel="stylesheet" type="text/css" />
<script language="JavaScript" src="../../resources/script/globalScript.js" type="text/JavaScript"></script>
I cannot figure out where to put the resources folder on my local machine so the pages will link correctly when running a project on my embedded server in JDev. Can anyone please help?

Hi,
the embedded OC4J has its configuration files at
\jdeveloper_installdir\jdev\system\oracle.j2ee.<version>\embedded-oc4j
However, if you use relative addressing then web applications try to find them relative to the public_html directory of the Viewlayer project

BAM and Oracle application server 10.1.3???

Hi,
I would like to understand more about integration between BAM and OAS.
I remember I read a document that stated that BAM was included (or was integrated) as part of OAS 10.1.3, however I installed it and still don;t see how it is integrating with OAS.
Also, in one of the Tutorials it mentions this:
"Note –if you are using Oracle Application Server with opmn process, the following
additional files are required in the above path:
C:\OracleBAM\OC4J\opmn\lib\optic.jar
Copy the entire Application Server “opmn” directory to c:\oraclebam"
So... are there any additional steps for the OAS and BAM integration?
I am still learning BAM but mi goal is install it as part of EBS(order Manegemnet)-BPEL-OTM (oracle Transportation) integration installation I currently have.
If it can be integrated can it be done using iAS 10.1.2.0.2 instead?
Thanks

Its recommended that you should use same versions of OAS and Oracle BAM.
For integration between OAS components and BAM you can check BAM tech notes (http://www.oracle.com/technology/products/integration/bam/10.1.3/htdocs/1013_support.html#technotes)
Hoping it will help you.

Hi,
can we Install Oracle Identity Manager 9.1.0.2 version on Oracle Weblogic server 11h R1 b(10.3.1)?
Is it OIM 9.1.0.2 compatible to install on Oracle Weblogic server 11h R1 b(10.3.1).
Early response is appreciated

Check this
http://www.oracle.com/technology/software/products/ias/files/idm_certification_101401.html#BABGBGHI
And Oracle has mentioned that
*2.1 Certified Application Servers*
Note: There is no change in application server certification from
release 9.1.0.1 to release 9.1.0.2.
Oracle WebLogic Server 10.3
But you can try with new version of Weblogic. It shouldn't create any problem.

RAID configuration down and OS

Out of memory using Windows Server 2003 and Oracle 9.2.0.3

Hi,
I just installed both Windows Server 2003 and Oracle 9.2.0.3. The server I am using has 4 gigabytes of memory installed, and windows shows that to be the actual physical memory on the server. The paging file is 8 gigabytes for a total of 12 gigabytes of virtual memory.
Using the Oracle Database Configuration Assistant, I create a new database using default values. After verifying the installation worked OK (database started, queries ran), I attempted to change some of the memory parameters and was able to start the database using about 1.4 gigabytes of total SGA, with the O/S using about .3 gigabytes for a total of 1.7 gigabytes. I then attempted to change the buffer cache + 1 gigabyte for a total of 2 gigabytes. Now the database will not start and I get an out of memory error ora-27102 with an additional O/S memory error of "O/S Error: (OS 8) Not enough storage is available to process this command".
So, I have two problems:
1) With 4 gigabytes installed, and the O/S using only about 300 megabytes, why isn't Oracle able to take advantage of the memory on this machine past the 1.7 gigabytes (as reported by Windows task manager).
2) How do I change the spfile memory parameters so the database will start using spfile? I can start the database pointing to a pfile with lesser memory parameters, but I don't know how to effect change on the spfile, since I cannot start with the spfile.
Both these technologies (9.2.0.3 and Server 2003) are new to me, so any insight would be appreciated!
HERE ARE THE SPFILE PARAMETERS THAT WORKED:
SGA (M)
Shared Pool=104
Buffer Cache=960 ***
Large Pool=0
Java Pool=64
Total SGA=1128
SGA Max Size=1321
Aggregate PGA Target=1500
Current PGA Allocated=22868KB
WINDOWS MEMORY INFO FROM TASK MANAGER SHOW:

Peak=1925276
*** When I change this to 2048 the database did not start.
Thank you.

CREATE SPFILE
Purpose
Use the CREATE SPFILE statement to create a server parameter file from a client-side initialization parameter file. Server parameter files are binary files that exist only on the server and are called from client locations to start up the database.
Server parameter files let you make persistent changes to individual parameters. When you use a server parameter file, you can specify in an ALTER SYSTEM SET parameter statement that the new parameter value should be persistent. This means that the new value applies not only in the current instance, but also to any instances that are started up subsequently. Traditional client-side parameter files do not let you make persistent changes to parameter values. Because they are located on the server, these files allow for automatic database tuning by Oracle and for backup by Recovery Manager (RMAN).
To use a server parameter file when starting up the database, you must create it from a traditional text initialization parameter file using the CREATE SPFILE statement.
All instances in an Real Application Clusters environment must use the same server parameter file. However, when otherwise permitted, individual instances can have different settings of the same parameter within this one file. Instance-specific parameter definitions are specified as SID.parameter = value, where SID is the instance identifier.
The method of starting up the database with a server parameter file depends on whether you create a default or nondefault server parameter file. Please refer to "Creating a Server Parameter File: Examples" for examples of how to use server parameter files.
See Also:
CREATE PFILE for information on creating a regular text parameter file from a binary server parameter file
Oracle9i Database Administrator's Guide for information on pre-Oracle9i initialization parameter files and Oracle9i server parameter files
Oracle9i Real Application Clusters Administration for information on using server parameter files in a Real Application Clusters environment
Prerequisites
You must have the SYSDBA or the SYSOPER system privilege to execute this statement. You can execute this statement before or after instance startup. However, if you have already started an instance using spfile_name, you cannot specify the same spfile_name in this statement.
Syntax
create_spfile::=
Text description of create_spfile
Semantics
spfile_name
This clause lets you specify a name for the server parameter file you are creating.
If you do not specify spfile_name, Oracle uses the platform-specific default server parameter filename. If spfile_name already exists on the server, this statement will overwrite it. When using a default server parameter file, you start up the database without referring to the file by name.
If you do specify spfile_name, you are creating a nondefault server parameter file. In this case, to start up the database, you must first create a single-line traditional parameter file that points to the server parameter file, and then name the single-line file in your STARTUP command.
See Also:
"Creating a Server Parameter File: Examples" for information on starting up the database with default and nondefault server parameter files
Oracle9i Database Administrator's Guide for Windows (or other appropriate operating system specific documentation) for default parameter file names
pfile_name
Specify the traditional initialization parameter file from which you want to create a server parameter file.
If you specify pfile_name, the parameter file must reside on the server. If it does not reside in the default directory for parameter files on your operating system, you must specify the full path.
If you do not specify pfile_name, Oracle looks in the default directory for parameter files on your operating system for the default parameter filename, and uses that file. If that file does not exist in the expected directory, Oracle returns an error.
Note:
In a Real Application Clusters environment, you must first combine all instance parameter files into one file before specifying it in this statement to create a server parameter file. For information on accomplishing this step, see Oracle9i Real Application Clusters Setup and Configuration.
Examples
Creating a Server Parameter File: Examples
The following example creates a default server parameter file from a client initialization parameter file named t_init1.ora:
CREATE SPFILE
FROM PFILE = '$ORACLE_HOME/work/t_init1.ora';
Note:
Typically you will need to specify the full path and filename for parameter files on your operating system. Please refer to your Oracle operating system documentation for path information.
When you create a default server parameter file, you subsequently start up the database using that server parameter file by using the SQL*Plus command STARTUP without the PFILE parameter, as follows:
STARTUP
The following example creates a nondefault server parameter file s_params.ora from a client initialization file named t_init1.ora:
CREATE SPFILE = 's_params.ora'
FROM PFILE = '$ORACLE_HOME/work/t_init1.ora';
When you create a nondefault server parameter file, you subsequently start up the database by first creating a traditional parameter file containing the following single line:
spfile = 's_params.ora'
The name of this parameter file must comply with the naming conventions of your operating system. You then use the single-line parameter file in the STARTUP command. The following example shows how to start up the database, assuming that the single-line parameter file is named new_param.ora:
STARTUP PFILE=new_param.ora

Request procedure for migrating PPC 10.4 Server setup to Intel 10.4 Server

Here's the background: I've got a G5 Xserve running 10.4.11 Server. It's and OD Master, Windows PDC and AFP, NFS & SMB file server for my whole department. We've purchased a new Intel Xserve (prior to Leopard - I'm not ready to go there yet), but I'm uncertain about the procedure for moving the setup from the G5 to the Intel box, keeping everything the same and working. I'm keeping the hostname the same, too.
What's really unclear (since there's no specific documentation on PPC -> Intel migration) is the order in which to do the OD Replica to Master promotion, the Windows BDC -> PDC promotion and the running of "changeip" to use the original host name on the new machine. I've botched the migration up three times so far, and I'd like to get it right the next time.
I know there can't be two Windows PDCs running concurrently, so I'm assuming that's the last step, but I'm really having trouble with knowing when to run changeip and whether or not the original machine should be running at the same time while changeip is run. Should the OD Replica be promoted before changeip?
If anyone's moved the functionality of a PPC 10.4 Server to an Intel 10.4 Server and moved the name of the system along with it, I'd love to hear from you.
Thanks in advance for your help!

NVARCHAR - NVARCHAR2 datatype mapping between sql server and oracle.

Question regarding size allocation that occurs for NVARCHAR columns in sql server to NVARCHAR2 in Oracle in the migration tool.
The migration tool has converted NVARCHAR columns to be twice their size as NVARCH2 in Oracle. Example, a table whose column is mycol NVARCHAR(40) gets migrated as mycol NVARCHAR2(80).
In SQL Server land, the designation of a column as NVARCHAR(40) will physically store the column as 80 bytes. However, as I understand from this excerpt (taken from here: http://www.oracle.com/technology/oramag/oracle/03-nov/o63tech_glob.html), that Oracle in essence will do the same thing for NVARCHAR2:
To make it easy to allocate proper storage for Unicode values, Oracle9i Database introduced character semantics. You can now use a declaration such as VARCHAR2(3 CHAR), and Oracle will set aside the correct number of bytes to accommodate three characters in the underlying character set. In the case of AL32UTF8, Oracle will allocate 12 bytes, because the maximum length of a UTF-8 character encoding is four bytes (3 characters * 4 bytes/character = 12 bytes). On the other hand, if you're using AL16UTF16, in which case your declaration would be NVARCHAR2(3), Oracle allocates just six bytes (3 characters * 2 bytes/character = 6 bytes). One difference worth noting is that for UTF-8, a declaration using character semantics allows enough room for surrogate characters, whereas for UTF-16 that is not the case. A declaration such as NVARCHAR2(3) provides room for three UTF-16 code units, but a single supplementary character may consume two of those code units.
As I read this, NVARCHAR(40) in sql server should be equivalent to NVARCHAR2(40) in Oracle and not NVARCHAR2(80) as it gets translated to - am I missing something? We have a rather large database to migrate so I need to get this size allocation right (and I obviously don't want to truncate any data).
Thanks -

Right - well, that's what I'm suggesting is that NVARCHAR(8) in SQL Server is equivalent to NVARCHAR2(8) in Oracle. Truncation will occur after 8 of any character, including, say, double byte Kanjii characters, which would physically store 16 bytes in the NVARCHAR(8) NVARCHAR2(8) column defn. I tried that in both SQL Server and Oracle, and the behavior is the same.
Also, technically, NVARCHAR2(8) and VARCHAR2(8 CHAR) is roughly the same in terms of behavior, except that in the first case, the physical storage is 16 bytes, while in the second case, it's 24 bytes (to account for 'supplemental' characters or true UTF-8 compliance). Same truncation occurs after 8 of -any- character be it single byte ascii or double byte kanjii, which is the behavior I expect.
Thanks for looking into this. What I decided to do was the following:
What was originally defined in SQL Server as varchar (and translated to VARCHAR2 with the CHAR designation), I removed the CHAR designation since I truly want that number of bytes to be stored, and not characters (for columns I do not care about UTF8 or 16 compliance - that will also mimic the same behavior I currently have on the SQL Server side. For anything that was nvarchar in SQL Server, I went ahead and created them as VARCHAR2 with the CHAR designation, with the same size (not double the value as was in SQL Server which the documentation says it gets translated to). I did this since we probably will need true UTF-8 compliance down the line, and since I had the hood open, it was easy enough to do. I could also have converted NVARCHAR(n) to NVARCHAR2(n) (and not n*2) as what was happening in the migration.
I tested strings in both cases, and I think I have my solution.

Run Oracle Web Logic and Oracle Application Server 10g on same server

Since oracle has chosen to release adf faces 11g, before the SOA suite 11g is released, we are facing the challenge to run both Oracle Web logic and Oracle Application Server 10g on the same server.
If anyone have any experience in this setup or has knowledge of other feasable setups please let me know.
Regards.
Jan

What version of Oracle Application Server 10g are you installing?
If you are installing 10gR2 (v10.1.2.x) have you taken a look at point #70 in "Table 2 Additional Information for Certified Platforms" section here?
