Problems with spfile. How to change database parameters
Hello
My Oracle database is 10.2.0 and SAP version is NW2004s. I am having errors in alert.log file
Thread 1 cannot allocate new log, sequence 3959
Checkpoint not complete
Sun Aug 27 01:38:12 2006
I have changed the parameter log_buffer from 14274560 to 1048576 following the SAP Note 830576. I changed the pfile and created a spfile from this pfile. Now the pfile and spfile reflect the parameter log_buffer as 1048576.
But surprisingly, when I say
SQL> show parameter log_buffer
NAME TYPE VALUE
log_buffer integer 14274560
Even after pfile and spfile reflecting 1048576 value for log_buffer, the database is showing this old value. Kindly let me know how to change the log_buffer parameter.
hi,
check which file it is reading
sql>sho parameter spfile
If it is reading spfile
issue alter system set log_buffer=<value> scope=spfile;
down and bring up database
If it is not reading spfile means reading pfile change parameter in INIT<SID>.ORA file
move all files which starts with spfile in dir $ORACLE_HOME/dbs to backup location
connect to database
create spfile from pfile
check $ORACLE_HOME/dbs only one spfile<sid>.ora exists
bring up database
and look for log_buffer
I guess ur changing in some other file which oracle is not reading.
or u can issue startp pfile='path';
then u can create spfile and issue startup force.
regards
Vinod

How to Change Database parameters as suggested by EWA report
Dear Experts,
As per EWA report , i have been asked to change several DB parameters as per note 0124361 . Should i go aghead and change the parameters ? What is the procedure of chaging those parameters? what is the real process that should be followed ? Please revert.Points guaranteed.
Regards,
SomyaRun "brspace -f dbparam"
Select option 1 "Change parameter value" and change the parameters. After changing select option 3 to create a new init.ora.
If you change parameters that have the scope "spfile" oracle requires a restart. If you only change parameters with scope "both" you don't need a restart of oracle. This changes are affected on the fly.
To restart oracle:
connect / as sysdba
SQL> shutdown
SQL> startup
You don't need to stop SAP if you only change oracle parameters. SAP reconnects automatically if the database is up. -

Tell me for Dw MX2004 & CS4 ?
If I start with Transitional 1.0 XHTML and want to change to Strict 1.0 XHTML the only way is modify code or make a new doc ?Using CS4, there are a few ways to do it:
1. when creating a new document - you can select the doc type preference.

3. If you start with one doctype and want to convert it to another use: -
How to change NLS parameters in Oracle XE?
Hi
I have to change some parameters in database using Oracle XE server but I don't know how to do it. I must change these parameters:
NLS_CHARACTERSET
NLS_NCHAR_CHARACTERSET
How to do it?
Thanks for help.Thanks, but I'm newbie and I have to ask you about more details :)
What do you mean when you saying: init file (or spfile)? Where can I find these files?
Registry entry (NLS_LANG) is correct, but when I'm using web based administration application I can see more NLS settings. Unfortunately I can't change them :(
Using XE version I can't (I'm not sure about that) create another instance, there is only one instance created by installer. Is it possible to change NLS settings in this case? -
How to change NLS parameters in SQL Developer?
I think that Oracle National Language Support is quite confusing. How can I easily change NLS parameters for SQL Developer (for all connections) to match exactly those that my database is using?
Hello,
SELECT 5/8 x FROM dual;F9 -> 0.625
Change decimal separator in preferences
F9 -> 0,625
It is different when I execute a query/script with F5, then I always get 0.625
SELECT * FROM nls_session_parameters
WHERE parameter = 'NLS_NUMERIC_CHARACTERS';
PARAMETER VALUE
NLS_NUMERIC_CHARACTERS .,
SELECT 5/8 x FROM dual;
X
0.625
Change settings
SELECT * FROM nls_session_parameters
WHERE parameter = 'NLS_NUMERIC_CHARACTERS';
PARAMETER VALUE
NLS_NUMERIC_CHARACTERS ,.
SELECT 5/8 x FROM dual;
X
0.625Even changing the settings with ALTER SESSION makes no difference
ALTER SESSION SET NLS_NUMERIC_CHARACTERS = ',.';
SELECT * FROM nls_session_parameters
WHERE parameter = 'NLS_NUMERIC_CHARACTERS';
PARAMETER VALUE
NLS_NUMERIC_CHARACTERS ,.
SELECT 5/8 x FROM dual;

0.625
ALTER SESSION SET NLS_NUMERIC_CHARACTERS = '.,';
SELECT * FROM nls_session_parameters
WHERE parameter = 'NLS_NUMERIC_CHARACTERS';
PARAMETER VALUE
NLS_NUMERIC_CHARACTERS .,

0.625It seems the script output does not care about my settings :-(

How to Change Database of Report before Exporting?
I am having difficulties changing the database that the report should run against.
We are using Oracle. In the past when scheduling a report through CE, I would manipuate the Desktop.ReportLogons object. For Oracle I simple changed the CustomServerName, CustomUserName, and CustomPassword properties. Everything worked fine when the report was scheduled and ran.
Now I am doing an on-demand report without an interactive viewer. I am doing everything in code using RasAppFactory and the ReportClientDocument.
I am looking at the DatabaseController of ReportClientDocument. I thought I could just use the LogonEx method passing in the server, user, password, and an empty string for the database since for Oracle connections you only specify server and not database. However, it is still trying to connect to the defined database.
Can someone point me to an Oracle specific example of how to properly change database info when report runs?
Do I need to be using other methods like one of the SetTableLocation methods?
Thanks in advance for any help.Hello, Stephen;
You are correct, with Oracle you do not need the Database property.
The person logged on to Business Objects Enterprise through the RAS .NET application would need rights to make the change in database connections. Can the usr with the same logon make the change directly in Enterprise?
The ReportClientDocument separates the Server Name and Database from the User ID and Password with the PropertyBag. The convenience methods such as LogonEx will only change the User ID and Password. To change all four properties you need the full RAS logon code.
The full logon for RAS would use code as shown below.

How to configure Database parameters to Spatial?
Say, when creating the database, you choose the preconfigured "GENERAL PURPOSE" for using it with mapserver and ORACLE SPATIAL.
Is it ok, to leave it like that?
Or is it a must to change some parameters?
Also, which parameters will be critical if I dont change them? or which one will speed up my queries?
Thanks
By the way.
8GB RAM
4 cores 1 cpu
2 TB HDDIs it ok, to leave it like that?The main thing you need to do is to adjust the memory parameters to suit your available memory. But this is nothing to do with spatial - it is what you would do regardless of the expected use of the database. You didn't mention the database version, so I assume 11g. Therefore you need to adjust the memory_target parameter.
You also didn't mention the operating system and whether it is 32 or 64 bit. Depending on the combination of those, you'll be able to make more or less use of your 8GB of RAM.
Also, which parameters will be critical if I dont change them? The default value of the vast majority of parameters are appropriate for the database template. Parameters related to redo logging often need some tuning to suit your workload.
or which one will speed up my queries?There is no "go faster" parameter. As a general rule, changing parameters is not the primary method of making the database perform faster. Writing efficient SQL and designing your system to reduce unnecessary processing and I/O is.

Big problem with a select using remote database
Hi Guy.
I have a big problem with a simple query, but this is a scenario.
Actuallly I'm in Alexandria - Egypt with a server with Oracle 10.2.0.4 database 32 bit on linux Red Hat as 4.8. the server can connect to another database oracle but 9.2.0.6 installed on Red Hat As 4.5 placed in Milano Italy . Ttwo networks are connected via two adsl cisco router with firewall and Vpn functions. In Egypt there isn't a very good adsl.
In Alexandria, I'm trying to connect to database in Italy with sqlplus. The sqlplus connected I write.. select * from addetti and all work fine.
My problem is that when I try to make the same select on a table with many columns oracle database kill me a session.
My table (ic_lav) is long 174 colums 1924 byte for row. Well when I write a query with select * from ic_lav all oracle close my session.
So I began to change my query I start to
select field1 from ic_lav... and work
select field1,field2,field3,..........field50 from ic_lav and work
select field1,field2,field3,..........field70 from ic_lav and doesn't work
the select work with 68 columns
problem: the query with more then 1064 byte for row doesn't work.
I've tryed with anoter big table with the same problem, but the select fwork with 65 columns...
Iit is obvious that there is any problem with the limit of the query.
The same query (select * from ic_lav) in localMilano)l work fine.
The same query (select * from ic_lav) in vpn with a better adsl line and openvpn software (NO CISCO firewall) WORK FINE.
The same query connectetd in Milano with a vpn make with analogic modem and remote access by windows work fine.
the query (make on my laptop connectet with vpn by cisco doesn't work.
In cisco firewall we haven't any error (cisco man tell me so)
on database 9 I found :
*** 2009-06-12 09:49:45.509
*** SESSION ID:(66.44406) 2009-06-12 09:49:45.497
FATAL ERROR IN TWO-TASK SERVER: error = 12152
*** 2009-06-12 09:49:45.509
ksedmp: internal or fatal error
Current SQL statement for this session:
select * from ic_lis where ditta
----- Call Stack Trace -----
but I don't understand why the lost connection problem (bug 3816595 A processstate dump is produced for a lost connection (12152) ) is caused by len of row
Anybody have some idea ?
Thank youMy table (ic_lav) is long 174 colums 1924 byte for row. Well when I write a query with select * from ic_lav all oracle close my session.Do you get any error?
If the query length is a problem, you could create a view and query the view instead to see if this problem is resolved. -
