Oracle 10g Deprecated parameters !!
We are planning to upgrade the database.
I ran the u101iu.sql before the upgrade to know the
Deprecated parameters and obsolete parameters.
From Upgrade guide : it tells me the following parameters
have been obsolete :
DBLINK_ENCRYPT_LOGIN
HASH_JOIN_ENABLED
LOG_PARALLELISM
MAX_ROLLBACK_SEGMENTS
MTS_CIRCUITS
MTS_DISPATCHERS
MTS_LISTENER_ADDRESS
MTS_MAX_DISPATCHERS
MTS_MAX_SERVERS
MTS_MULTIPLE_LISTENERS
MTS_SERVERS
MTS_SERVICE
MTS_SESSIONS
Question is : Should I keep them in my initSID.ora file or
REMOVE them completely ?
If I remove them how the oracle will know about the
Dispatcher circuits and other information since I would like
to use shared server with dispatcher ?Right now Shared_server
value is 2 in initSID.ora file for 8.1.7 version.
Please let me know.
From,
Pranav
Just to add little bit -
My concern is for following parameters :
MTS_CIRCUITS
MTS_DISPATCHERS
MTS_LISTENER_ADDRESS
MTS_MAX_DISPATCHERS
MTS_MAX_SERVERS
Should I remove them or keep them for 10g upgrade ?
If I remove MTS_MAX_servers or mts_dispatcher,
How would I be able to user oracle in shared server mode
with more than one dispatcher ?
Please adivse.
Thanks in advance.

Oracle 10g R2 vs Oracle 10g;;;Plz Help Me
Hi all;
I'm preparing my first OCA exam ; Oracle Database 10g: Administration I. I 'm doing my preparation basically from 2 books ; Sybex Book OCA-Exam and All-in-One Exam Guide book.
Both books 're based on the first release of Oracle 10g.
My questions 're :
- What's the diffrence between Oracle 10g R2 vs Oracle 10g R1?
- What's New in Oracle 10g R2 (parameters, default parameters values, features...)?
thanks a lot,
Best REgards,
W
Edited by: OracleJavaLinux on Oct 30, 2008 8:01 AMWell satish has given link for the difference in both the versions. I shall add to this that at this moment of writing,there is not anything which makes the exams depend on the release 2.The sybex books would be good enough but I shall recommend to attend Oracle Univ training for the same.
You can go ahead with the exam by preparing from these books, no issues would be there.

URGENT !!!!!!!!!How to pass parameters to Forms from Reports(Oracle 10g)
Hai
I can call a form named "ABC" from one Report, using "hyperlink" . The URL is
http://....../forms90/f90servlet?form=c:/ABC&userid=a/a@a
Now I want to pass 2 parameters (that are received in that report) to the form ABC.
I am using Oracle 10g.
What to do?
Please reply soon.
I am eagerly waiting for the solution.
Please Help.
ByeHai
Thank u for the reply.
Is it possible to pass the variable instead of values.
My report receives 2 parameters named p1 & p2. Actually I want to pass that parameters to the form from the report.
I have tried as You said.
//http/.........&otherparams=param1=:p1+param2=:p2
Then the form receives the ":p1" as the value, it does not take the value of that variable p1.
Please Reply Soon.

Manually Migrating from Oracle 10g to 11g
Hello, I'm currently a student in an Oracle DBA class. I'm totally new to the Oracle world.
One of our final assignments concerns upgrading Oracle instances without the use of DBUA.
I've currently got Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 and am trying to upgrade to 11.1.0.7.0
This is all inside of VirtualBox, running Windows Server 2008. I've been using 10g with absolutely no issues for the duration of this class.
I successfully installed 11g, choosing to install the software only and not use dbua.
I changed my environment variables to point towards the 10g installation; ORACLE_HOME, ORACLE_SID, PATH, and LD_LIBRARY_PATH.
Then logged into 10g's SQLPlus and ran utlu111i.sql, which ran successfully. I issued a shutdown immediate and exited SQLPlus.
Changed my environment variables to point towards the 11g home and set ORACLE_SID as the 10g database name. I was able to log into 11g's SQL plus, was told I was connected to an idle instance, which I expected. I issued a startup upgrade command, and then attempted to run catupgrd.sql, but got an error stating that I had to run the script from 11g.
If I don't set the environment variables then when I try to log into 11g's sqlplus, I get an ORA-12560: TNS:protocol adapter error... I've tried reinstalling 11g from scratch, but to no avail. My instructor and I have been emailing back and forth frequently over the past few days but we have not been able to reach a solution, so I thought I would see if I could pick your brains.
Here's all of the terminal output from the process:

Problem with JDBC driver for Oracle 10g
Hi.
I've successfully accessed a MySQL database via a DataSource from a servlet (that uses a DAO). However, when I try to do the same with an Oracle 10g Database, I get the error message:
Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
I'm using J2SE1.5.0/5.0 and ojdbc14.jar, the latter of which I downloaded this afternoon as the latest driver JAR available on the Oracle site. As with the MySQL driver, I've placed it in the commons\lib folder within Tomcat. (I've also, of course, made the necessary modifications to server.xml and web.xml.)
Upon examining the ReadMe file at the top of the Oracle download page, I found that the oracle.jdbc.driver package is now deprecated and all references to oracle.jdbc.driver should be replaced with oracle.jdbc. However, I got a similar error message when I tried this modification. Upon examining the contents of ojdbc.jar, I found that the driver was there and that it was, in fact, still oracle\jdbc\driver\OracleDriver!
It appears as though the Oracle site has not been updated with a driver that matches its latest documentation. However, this does not explain why the driver is not even being loacted when it is in the correct place. Can anybody shed any light on this? Any help would be much appreciated.
Thanks in anticipation.
Cheers.
JanI've successfully accessed a MySQL database via a
DataSource from a servlet (that uses a DAO). However,
when I try to do the same with an Oracle 10g
Database, I get the error message:
Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver'
That's different from a ClassNotFoundException.
>
I'm using J2SE1.5.0/5.0 and ojdbc14.jar, the latter
of which I downloaded this afternoon as the latest
driver JAR available on the Oracle site. So you got ojdbc14.jar or ojdbc14_g.jar under the 10g drivers?
As with the
MySQL driver, I've placed it in the commons\lib
folder within Tomcat. I think it's a better idea to put in the WEB-INF/lib directory of your Web app rather than commons/lib. WAR files are a very good idea, too.
(I've also, of course, made the
necessary modifications to server.xml and web.xml.)So you're using a JNDI data source? It sounds to me like that's where the problem is.
You should not have to edit the server.xml at all. If you put the <ResourceParams> in a context XML file with the same name as your WAR file into the TOMCAT_HOME/webapps directory it'll be picked up automatically. (It might also be accessible in the META-INF directory for your app, but I haven't done it that way.)
Upon examining the ReadMe file at the top of the
Oracle download page, I found that the
oracle.jdbc.driver package is now deprecated and all
references to oracle.jdbc.driver should be replaced
with oracle.jdbc.
However, I got a similar error
message when I tried this modification. Upon
examining the contents of ojdbc.jar, I found that the
driver was there and that it was, in fact, still
oracle\jdbc\driver\OracleDriver! The fully-resolved class name you should be using MUST match the class that's in the ojdbc14.jar that you're using. Look in the JAR for the definitive answer: the one that I downloaded is still using the oracle.jdbc.driver package for OracleDriver.class. Ignore the docs - use the name that's in the JAR.
It appears as though the Oracle site has not been
updated with a driver that matches its latest
documentation. That often happens with docs.
However, this does not explain why the
driver is not even being loacted when it is in the
correct place. Can anybody shed any light on this?
Any help would be much appreciated.I think the problem lies in your web.xml and server.xml
I'd recommend that you decouple the JDBC from the Web app for now. See if you can connect to Oracle using a simple desktop app and leave the Web piece out of the equation for now. Once you can do that, you'll be certain that the parameters you're using are correct and you can turn your attention to getting the Tomcat configuration right.
PS - I'm using Oracle 9.2.0.1 and Tomcat successfully right now, so it can be done. -
Oracle 10g on solaris 10 : kernel parameter warning
I am installing oracle 10g on Solaris 10.
I have a warning on kernel parameter missing (shminfo_shmmax for example) during the system check.
I understood that with the 10 version of solaris these parameters are replaced by ressources control and I have checked them. They are correctly setted.
Need I do something before continue the install to release the warning or can I bypass this issue and continue the install as I have no warning ?
Thanks for your answers.
Sorry for my english.You are right. Since Solaris 10 kernel parameters settings in /etc/system is obsolete and some parameters are deprecated.
The steps how to configure required parameters you can find in my paper (step #1.): http://ivan.kartik.sk/oracle/install_ora10gR2_solaris.html
I bypass this issue and continue the install as I have no warning You can safely bypass this issue during installation process but you should set these parameters after installation. -
Solaris 10, Oracle 10g and ORA-27102 out of memory
After much STFW'ing, RTFM'ing and experimenting I finally got Oracle 10g to start a database on a SunBlade 100 with 512MB of memory and Solaris 10. As most of the replies on the web about error 27102 "out of memory" address solutions in Solaris 8 and 9, I thought I should post a clear description of the solution here.
Unlike earlier releases of Solaris, most of the system parameters needed to run Oracle are already set properly, so the only one you need is the maximum shared memory parameter. In earlier versions this was called SHMMAX and was set by editing the /etc/system file and rebooting. With Solaris 10 you set this by modifying a "Resource Control Value". You can do this temporarily by using prctl, but that is lost at reboot so you will need to add the command to the oracle user's .profile. The other option is to create a default project for the oracle user:
projadd -U oracle -K "project.max-shm-memory=(priv,2048MB,deny)" user.oraclewhat this does:
- makes a project named "user.oracle" with the user oracle as it's only member.
- because the name was of the form "user.username" it becomes the oracle user's default project.
- the value of the maximum shared memory is set to 2gb, you might want to use a larger value here if you have more memory and swap.
- no reboot is needed, the user will get the new value at their next login.thanks buddy. I was in this same tricky situation. and ur post solved my prblem.
Is this a bug with solaris 10.
Later i discovered.. on Oracle documentation that.. there r sum parameters that needed to be taken care while pre-installation of Oracle binaries.
Here is the excerpts.
The Oracle installer recognizes kernel parameters set using this method, but it is now deprecated in favour of resource control projects, explained below.
As the root user, issue the following command.
projadd oracle
Append the following line to the "/etc/user_attr" file.
oracle::::project=oracle
If you've performed a default installation, it is likely that the only kernel parameter you need to alter is "max-shm-memory". To check the current value issue the following command.
# prctl -n project.max-shm-memory -i project oracle
project: 100: oracle
NAME PRIVILEGE VALUE FLAG ACTION RECIPIENT
project.max-shm-memory
privileged 254MB - deny
system 16.0EB max deny
To reset this value, make sure at least one session is logged in as the oracle user, then from the root user issue the following commands.
# prctl -n project.max-shm-memory -v 4gb -r -i project oracle
# projmod -s -K "project.max-shm-memory=(priv,4gb,deny)" oracle
The first dynamically resets the value, while the second makes changes to the "/etc/project" file so the value is persistent between reboots.
# cat /etc/project
system:0::::
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
oracle:100::::project.max-shm-memory=(priv,4294967296,deny)
The Oracle installer seems incapable of recognising kernel parameter set using resource control projects, but if you ignore the warnings the installation completes successfully.Even this method works.

Oracle 10G New Feature........Part 1
Dear all,
from last couple of days i was very busy with my oracle 10g box,so i think this is right time to
share some intresting feature on 10g and some internal stuff with all of you.
Have a look :-
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Oracle 10g Memory and Storage Feature.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1.Automatic Memory Management.
2.Online Segment Shrink
3.Redolog Advisor, checkpointing
4.Multiple Temporary tablespace.
5.Automatic Workload Repository
6.Active Session History
7.Misc
a)Rename Tablespace
b)Bigfile tablespace
c)flushing buffer cache
8.ORACLE INTERNAL
a)undocumented parameter (_log_blocks_during_backup)
b)X$ view (x$messages view)
c)Internal Structure of Controlfile
1.Automatic memory management
================================
This feature reduce the overhead of oracle DBA.previously mostly time we need to set diff oracle SGA parameter for
better performance with the help of own experience,advice views and by monitoring the behaviour
of oracle database.
this was just time consuming activity.........
Now this feature makes easy life for oracle DBA.
Just set SGA_TARGET parameter and it automatically allocate memory to different SGA parameter.
it focus on DB_CACHE_SIZE
SHARED_POOL_SIZE
LARGE_POOL
JAVA_POOL
and automatically set it as
__db_cache_size
__shared_pool_size
__large_pool_size
__java_pool_size
check it in alert_log
MMAN(memory manager) process is new in 10g and this is responsible for sga tuning task.
it automatically increase and decrease the SGA parameters value as per the requirement.
Benefit:- Maximum utlization of available SGA memory.
2.Online Segment Shrink.
==========================
hmmmmm again a new feature by oracle to reduce the downtime.Now oracle mainly focus on availablity
thats why its always try to reduce the downtime by intrducing new feature.
in previous version ,reducing High water mark of table was possible by
Exp/imp
or
alter table move....cmd. but on these method tables was not available for normal use for long hrs if it has more data.
but in 10g with just few command we can reduce the HWmark of table.
this feature is available for ASSM tablespaces.
1.alter table emp enable row movement.
2.alter table emp shrink space.
the second cmd have two phases
first phase is to compact the segment and in this phase DML operations are allowed.
second phase(shrink phase)oracle shrink the HWM of table, DML operation will be blocked at that time for short duration.
So if want to shrink the HWM of table then we should use it with two diff command
first compact the segment and then shrink it on non-peak hrs.
alter table emp shrink space compact. (This cmd doesn't block the DML operation.)
and alter table emp shrink space. (This cmd should be on non-peak hrs.)
Benefit:- better full table scan.
3.Redolog Advisor and checkpointing
================================================================
now oracle will suggest the size of redo log file by V$INSTANCE_RECOVERY
SELECT OPTIMAL_LOGFILE_SIZE
FROM V$INSTANCE_RECOVERY
this value is influence with the value of FAST_START_MTTR_TARGET .
Checkpointing
Automatic checkpointing will be enable after setting FAST_START_MTTR_TARGET to non-zero value.
4.Multiple Temporary tablespace.
==================================
Now we can manage multiple temp tablespace under one group.
we can create a tablespace group implicitly when we include the TABLESPACE GROUP clause in the CREATE TEMPORARY TABLESPACE or ALTER TABLESPACE statement and the specified tablespace group does not currently exist.
For example, if group1 is not exists,then the following statements create this groups with new tablespace
CREATE TEMPORARY TABLESPACE temp1 TEMPFILE '/u02/oracle/data/temp01.dbf'
SIZE 50M
TABLESPACE GROUP group1;
--Add Existing temp tablespace into group by
alter tablespace temp2 tablespace group group1.
--we can also assign the temp tablespace group on database level as default temp tablespace.
ALTER DATABASE <db name> DEFAULT TEMPORARY TABLESPACE group1;
benefit:- Better I/O
One sql can use more then one temp tablespace
5.AWR(Automatic Workload Repository):-
================================== AWR is built in Repository and Central point of Oracle 10g.Oracle self managing activities
is fully dependent on AWR.by default after 1 hr, oracle capure all database uses information and store in AWR with the help of
MMON process.we called it Memory monitor process.and all these information are kept upto 7 days(default) and after that it automatically purge.
we can generate a AWR report by
SQL> @?/rdbms/admin/awrrpt
Just like statspack report but its a advance and diff version of statspack,it provide more information of Database as well as OS.
it show report in Html and Text format.
we can also take manually snapshot for AWR by
BEGIN
DBMS_WORKLOAD_REPOSITORY.CREATE_SNAPSHOT ();
END;
**The STATISTICS_LEVEL initialization parameter must be set to the TYPICAL or ALL to enable the Automatic Workload Repository.

Advance version of statspack
more DB and OS information with self managing capabilty
New Automatic alert and database advisor with the help of AWR.
6.Active Session History:-
==========================
V$active_session_history is view that contain the recent session history.
the memory for ASH is comes from SGA and it can't more then 5% of Shared pool.
So we can get latest and active session report from v$active_session_history view and also get histortical data of
of session from DBA_HIST_ACTIVE_SESS_HISTORY.
v$active_session_history include some imp column like:-
~SQL identifier of SQL statement
~Object number, file number, and block number
~Wait event identifier and parameters
~Session identifier and session serial number
~Module and action name
~Client identifier of the session
7.Misc:-
========
Rename Tablespace:-
=================
in 10g,we can even rename a tablespace by
alter tablespace <tb_name> rename to <tb_name_new>;
This command will update the controlfile,data dictionary and datafile header,but dbf filename will be same.
**we can't rename system and sysaux tablespace.
Bigfile tablespace:-
====================
Bigfile tablespace contain only one datafile.
A bigfile tablespace with 8K blocks can contain a 32 terabyte datafile.
Bigfile tablespaces are supported only for locally managed tablespaces with automatic segment-space management.
we can take the advantage of bigfile tablespace when we are using ASM or other logical volume with RAID.
without ASM or RAID ,it gives poor response.
syntax:-
CREATE BIGFILE TABLESPACE bigtbs
Flushing Buffer Cache:-
======================
This option is same as flushing the shared pool,but only available with 10g.
but i don't know, whats the use of this command in prod database......
anyway we can check and try it on test server for tuning n testing some query etc....
SQL> alter system flush buffer_cache;
System altered.
++++++++++++++++++
8.Oracle Internal
++++++++++++++++++
Here is some stuff that is not related with 10g but have some intresting things.
a)undocumented parameter "_log_blocks_during_backup"
++++++++++++++++++++++++
as we know that oracle has generate more redo logs during hotbackup mode because
oracle has to maintain the a complete copy of block into redolog due to split block.
we can also change this behaviour by setting this parameter to False.
If Oracle block size equals the operating system block size.thus reducing the amount of redo generated
during a hot backup.
WITHOUT ORACLE SUPPORT DON'T SET IT ON PROD DATABASE.THIS DOCUMENT IS JUST FOR INFORMATIONAL PURPOSE.
b)some X$ views (X$messages)
++++++++++++++++
if you are intresting in oracle internal architecture then x$ view is right place for getting some intresting things.
X$messages :-it show all the actions that a background process do.
select * from x$messages;
like:-
lock memory at startup MMAN
Memory Management MMAN
Handle sga_target resize MMAN
Reset advisory pool when advisory turned ON MMAN
Complete deferred initialization of components MMAN
lock memory timeout action MMAN
tune undo retention MMNL
MMNL Periodic MQL Selector MMNL
ASH Sampler (KEWA) MMNL
MMON SWRF Raw Metrics Capture MMNL
reload failed KSPD callbacks MMON
SGA memory tuning MMON
background recovery area alert action MMON
Flashback Marker MMON
tablespace alert monitor MMON
Open/close flashback thread RVWR
RVWR IO's RVWR
kfcl instance recovery SMON
c)Internal Structure of Controlfile
++++++++++++++++++++++++++++++++++++
The contents of the current controlfile can be dumped in text form.
Dump Level Dump Contains
1 only the file header
2 just the file header, the database info record, and checkpoint progress records
3 all record types, but just the earliest and latest records for circular reuse record types
4 as above, but includes the 4 most recent records for circular reuse record types
5+ as above, but the number of circular reuse records included doubles with each level
the session must be connected AS SYSDBA
alter session set events 'immediate trace name controlf level 5';
This dump show lots of intresting information.
it also show rman recordes if we used this controlfile in rman backup.

Oracle 10g on HP-UX, Terrible Poor Performance!!
Hi All,
I setup an Oracle 10g on HP-UX 11iv1. Server is a HP 9000, 4 CPUs (750
MHZ). It is connected to Disk System 2405 (Virtual Array 7110). Fiber
Channels are connected at 2 GB speed.
I installed a cluster 10g database. First I installed CRS and after
that I installed oracle database. ( I want to test clustered database
with one instance)
I installed every thing line by line as oracle document wrote.
All the things, kernel parameters, patches, are like oracle wrote in
its document.
I installed Golden quality package June 2004.
I increased shmmax to 2.3 G . My SGA is 1.7 G And change some other
parameters as Sandy Gruver wrote in Best Practices for Oracle on HPUX.
I used oracle new storage system called ASM for this case.
When I put the system under the load, I was monitoring the system
carefully.
I started gmp. When we sent some quarries to database (It is not heavy
load, I tested it with a Linux system on proliant ML570 without any
problem), suddenly DISK section in gpm changed to red (critical ) I
read the warning. It said "Disk bottleneck probability = 100%". I
changed the output of disk report to "Report IO by Disk"
"DISK%" was 100% and "RAW IO RT" was about 1000 for two disks ( This
two disks dedicated for ASM). In this situation CPU idle time was 1% or
2% for all the CPUs but load average was about 1. Performance is not
acceptable at all ( In comparison with Oracle that installed on Linux).
Glance reported Disk was in Critical situation.
I think the problem is IO or something about Disks
I used HP Disk System 2405. Fibber channels on both server side and
Disk Array side are configured at 2 Gb and topologies are
PTTOPT_FABRIC.
Is it ok that RAW IO RT about 1000 for each LUN?
Why Disk% in glance/report IO BY Disk/ was 100%?
I found an error in STM logs about I/O.It said:
Entry type: I/O error
Product: Fiber Channel Interface
Logger: td
It logged this error about 12 times during the test.Any comment?
Regards,
HasanSorry, I have not a solution for your problem, but similar things happen on our installation on Solaris 5.8 with Oracle 10:
I have a banking business solution from Windows/SQL Server 2000 to Sun Solaris/ORACLE 10g migrated. In the test environment everything was working fine. On the production system we have very poor DB performance. About 100 times slower than SQL Server 2000!
Environment at Customer Server Side:
Hardware: SUN Fire 4 CPU's, OS: Solaris 5.8, DB Oracle 8 and 10
Data Storage: Em2
DB access thru OCCI [Environment:OBJECT, Connection Pool, Create Connection]
Depending from older applications it's necessary to run ORACLE 8 as well on the same Server. Since we have running the new solution, which is using ORACLE 10, the listener for ORACLE 8 is frequently gone (or by someone killed?). The performance of the whole ORACLE 10 Environment is very poor. As a result of my analyse I figured out that the process to create a connection to the connection pool takes up to 14 seconds. Now I am wondering if it a problem to run different ORACLE versions on the same Server? The Customer has installed/created the new ORACLE 10 DB with the same user account (oracle) as the older version. To run the new solution we have to change the ORACLE environment settings manually. All hints/suggestions to solve this problem are welcome. Thanks in advance.

Cannot get ODBC data source to talk to Oracle 10g for Windows
Problem description
I recently installed Oracle 10g on my laptop computer, which is running Windows 7. Everything went smoothly except for one crucial item: The ODBC data source I added keeps returning this error when I click the "Test Connection" button:
Testing Connection
Unable to connect
[Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed.
I was using the following ODBC driver
Oracle in OraDb10g_home1 (TNS Service Name = ORCL and User ID = scott)
This type of error happened, in one form or another for the three other Oracle drivers I have on my machine
Microsoft ODBC for Oracle
WinSQL Oracle
WinSQL Oracle Wire Protocol
These services are currently running (status = Started)
OractDBConsoleorcl
OracleMTSRecoveryService
OracleOraDb10g_home1iSQL*Plus
OracleOraDb10g_home1TNSListener
OracleServiceORCL
(NOTE: I entered the foregoing information by hand, since I was not able to copy-and-paste it. So be aware that there is a small possibility of a minor typo in case you plan to cut-and-paste it.)
If requested, I can provide the contents of these files
tnsnames.ora
sqlnet.ora
listener.ora
Other installations on the same computer
ODAC (ADO data provider for Oracle)
SQL Server 2009 Express
.NET 4
Visual Studio 2010
Any help would be greatly appreciated!OK, I went ahead and upgraded to Windows 7 Professional and I STILL get the same error messages when trying to get the Oracle ODBC driver to talk to Oracle 10g. Here are some screen shots that show what happened:
1) Select ODBC driver: http://yfrog.com/f3driverselectionp
2) Configure driver: http://yfrog.com/ccoracleodbcfororaclep
3) Test connection: http://yfrog.com/1goracleodbcfororacletestp
I also get the following error when I try to run SQL*Plus from the line command, even with no parameters:
C:\Users\Bruce>sqlplus
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
Any suggestions as to how I might to go about diagnosing (and fixing) this problem?
Thanks,

How to configure Oracle 10g to use 4GB memory
I'm trying to configure Oracle 10g to use >4GB memory. Have configured server boot.ini with required flags (/3GB /PAE). Rebooted server then created standard database, then connected to db instance and changed oracle parameters DB_BLOCK_BUFFERS, USE_INDIRECT_DATA_BUFFERS as required. Restarted DB instance, DB fails to restarted with SGA memory error. According to oracle user docs the SGA is nolonger in effect due to previous settings. Can you provide example of SPFILE with parameters settings that do work and use >4GB memory. Current server has 8GB, 2 x Dual XEON core/processors (i.e. 8 processors)
The recommended /3GB switches in the boot.ini file can only be used with the following operating systems editions (KB article 291988):
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Data Center Server
Microsoft Windows Server 2003, Enterprise Edition
Microsoft Windows Server 2003, Data Center Edition
Microsoft Windows Small Business Server 2003
Important: Windows 2000 and 2003 Server Standard Editions DO NOT SUPPORT /3GB Switch.
So if your OS is listed above, then you cannot have a larger SGA. -
About spfile creating in oracle 10g while creating a new database
hi everyone,
i had this problem while i was creating a new database in oracle 10g.when running the database script, it gives an error about invalid option for create temporary tablespace. is it necessary to have an spfile created in 10g. when the script was not working,we tried to create spfile which gives error tht it does not match the parameter db_name. its taking the default db_name=orcl itself..tis not taking our new db name.
im creating it manually through sql prompt not through DBCA.the problem is that its still accepting the default db name. please send me the solution with syntaxes.
thanxfirst of all, thanx for giuding me as im a student doing a course in this
what abt the creation of spfile.. in a documentation for steps in creating database, they have mentioned it as recommended in creating spfile.here are some notes regarding this ....for oracle 10g
Step 5: Create a Server Parameter File (Recommended)
Oracle recommends that you create a server parameter file as a dynamic means of maintaining initialization parameters. The server parameter file is discussed in "Managing Initialization Parameters Using a Server Parameter File".
The following script creates a server parameter file from the text initialization parameter file and writes it to the default location. The script can be executed before or after instance startup, but after you connect as SYSDBA. The database must be restarted before the server parameter file takes effect.
-- create the server parameter file
CREATE SPFILE='/u01/oracle/dbs/spfilemynewdb.ora' FROM
PFILE='/u01/oracle/admin/initmynewdb/scripts/init.ora';
SHUTDOWN
-- the next startup will use the server parameter file
EXIT
the error : db_name does not match with the parameter.
its still taking the default orcl database name -
Error while creating datasource userdsn for oracle 10g Errorcode (998)
while creating datasource userdsn for oracle 10g i am getting error "The setup routines for the oracle in OraDb10g_home1 odbc driver could not be loaded due to system error code 998" please give reply soon
Thanks for your reply , Steve.
I noticed that there is a default datasouce on the EM with the following parameters:
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="OracleDS"
location="jdbc/OracleCoreDS"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/OracleDS"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="scott"
password="->pwForScott"
url="jdbc:oracle:thin:@localhost:1521:oracle"
inactivity-timeout="30"
/>
The location and xa-location attributes that I use for my "test" data source are the same as the default one. So, could this be the issue?
What should be the values for location and xa-location attributes from my "test" data source?
Any help will be greatly appreciated.
Thanks,

Installing oracle 10g release 2 on spark solaris!! urgent help!
hi guys!
Am installing oracle 10g r2 on spark sun solaris. I did install the software without any pb, but when installing the database using dbca, I have this errors.
ORA-27154: post/wait create failed
ORA-27300: OS system dependent operation:semget failed with status: 28
ORA-27301: OS failure message: No space left on device
ORA-27302: failure occurred at: sskgpcreates
Edited my kernel parameters and in the /etc/system file, ai've added

Space aint an issue and dont know how to over come this error!
Should ai just install the db using scripts and run the neccessary .sql scripts instead of going through dbca?
junior DBA in distress.This appears to be because of low semaphores setting. Did you reboot your server after making the /etc/system parameter changes ?
