Disabling oracle trace in udump
Is there a way to disable this udump trace files?. I am using oracle 10g and i have set the following in init.ora
sql_trace=false
trace_enabled=false
oracle_trace_enable=FALSE
But still for every connection and query, trace file is getting generated
Maybe it's not instance level setting.. Consider following example:
SQL> SHOW PARAMETER trace
NAME TYPE VALUE
log_archive_trace integer 0
sec_protocol_error_trace_action string TRACE
sql_trace boolean FALSE
trace_enabled boolean FALSE
tracefile_identifier string
SQL> SELECT spid FROM v$process p, v$session s
2 WHERE s.paddr = p.addr
3 AND s.sid = (SELECt sid FROM v$mystat WHERE rownum = 1);
SPID
19935Then I'm checking if my session generates trace files:
[oracle@OEL5 trace]$ ls -la *19935*
ls: *19935*: No such file or directoryNothing.
SQL> exec dbms_session.session_trace_enable(TRUE, TRUE);
Procedura PL/SQL zosta│a zako˝czona pomyťlnie.
SQL> SELECT sysdate FROM dual;
SYSDATE
09/07/14
SQL>
[oracle@OEL5 trace]$ ls -la *19935*
-rw-r----- 1 oracle oinstall 2777 Jul 14 17:13 ORA111_ora_19935.trc
-rw-r----- 1 oracle oinstall 127 Jul 14 17:13 ORA111_ora_19935.trm

How To Disable OracleTrace
Since Oracle 7.3.2, the default behaviour has been to have OracleTrace enabled automatically. This feature is generally overlooked by DBAs; partly through ignorance but mostly because up until release 8i, OracleTrace wasn't really all that useful. That's all changed since 8i and 9i but the default behaviour has still been to have tracing enabled This causes a number of files to build up under $ORACLE_HOME/otrace/admin. If these files are not regularly cleared out, the first you'll hear about it is when the file system fills up or you notice that performance becomes mysteriously sluggish, especially when connecting. In fact I have seen database connect times rise up to about 5 minutes because of this.
If you are not interested in collecting this data, then simply turn it off. You can do this for individual users/clients or for all SQL*Net / Net8 / OracleNet connections as follows:
UNIX - bequeath or server-side connections
Set environment variable EPC_DISABLED=TRUE
NT or Windows2000 clients
In regedt32, go to
HKEY_LOCAL_MACHINE
-> SOFTWARE
-> ORACLE
Create a new registry value called EPC_DISABLED of type REG_SZ and set it to TRUE
For all OracleNet connections
Add ENVS="EPC_DISABLED=TRUE" to the server's $TNS_ADMIN/tnsnames.ora file. For example:
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=GROB)
(ORACLE_HOME=/u01/app/oracle/product/8.1.7)
(ENVS="EPC_DISABLED=TRUE")
Next time the database is down, delete the .dat files from $ORACLE_HOME/otrace/admin: process.dat, collect.dat and regid.dat. If you need to create them again (you might want to turn OracleTrace back on) you can create them with the $ORACLE_HOME/bin/otrccref command.
Oracle9i improvements
Oracle9i has introduced a wealth of new capability for OracleTrace. It now has it's own command line interface (otrccol) and you can fine-tune the information you collect into event sets which are defined in product definition (.fdf) files. A whole new set of init.ora parameters have been introduced to tell Oracle where the .fdf files live and to restrict the size of the .dat files generated. The parameter ORACLE_TRACE_ENABLE is used to turn tracing on or off. The default is FALSE.

How do i start an Oracle Trace? For a currently running session?
How do i start an Oracle Trace? For a currently running session? How do i read it?
How do i read it? Ohh forgot this one. That tracing will create a tracefile in udump directory and you need to run tkprof to parse that trace file so that you can read it. To find the udump dir type "show parameter user_dump_dest" at sqlplus prompt and then run tkprof like (from OS prompt):
tkprof file_name.trc file_name.txt sys=no
Type only tkprof for more option of this tool.

I gained a new database - and if it didnt have data in it or a PRODUCTION box I'd rebuild!
Windows Server 2003 Enterprise x64 Edition SP2 running 10g 10.2.0.3
Management Packs active: Database Diagnostics, Database Tuning, Database Configuration
user_dump_dest = c:\oracle\admiprod\udump
Executing:
select
u_dump.value || '/' ||
db_name.value || '_ora_' ||
v$process.spid ||
nvl2(v$process.traceid, '_' || v$process.traceid, null )
|| '.trc' "Trace File"
from
v$parameter u_dump
cross join v$parameter db_name
cross join v$process
join v$session
on v$process.addr = v$session.paddr
where
u_dump.name = 'user_dump_dest' and
db_name.name = 'db_name' and
v$session.audsid=sys_context('userenv','sessionid');
Results: C:\oracle\admin\prod\udump/prod_ora_388.trc (NOTE THE "/" IS CODED TO RETURN AS SUCH)
YET prod_ora_388.trc is NOT found at C:\oracle\admin\prod\udump OR anywhere on the C or associated D drives - any idea what is going on here, and if so how to correct it so the trc does show up?Did You enabled session tracing for that particular user?
If not, the of course You will find no trace file, just the possible name will be returned and path.
For first enable tracing, then look at trace directory for particular file.
And / is returned just because script is for unix. In your case you should replace it with \ as it is windows env.
and it's easier to identify trace files just adding some identifier to them with
alter session set tracefile_identifier ="some_name";
then in udump dierctory just search for this name. -
Dear Experts,
Can you advise how we can set oracle trace ON for a given session/piece of code.
Actually we have a datawarehouse which is populated overnight Mon-Sun.
One of the procedures in this load is failing with the error ORA-8103 object no longer exists.
The procedure is simply inserting data into a table. The table is not dropped during this process.
We did several investigations, even re-built the table and indexes, but still no success.
The most surprising part is that the error does not show up daily. It runs well for few days and then simply fails with the error above, intermittently.
As a result we though the option of tracing the root cause through the trace file.
However, since the load is huge, DBAs are not ready to set the trace on at the system level as they cannot afford so much of memory space being taken up by log files.
Do we have any option to set up the trace for the given procedure alone.. or within a given timestamp.
Thanks.Caitanya wrote:

Thanks.In DWH enviroenments you often load data from a distinct database via a DB link. The ORA-8103 can also happen when the link is (temporaily) not available. Or when some of the source tables are rebuild (synonym changed, table grants revoked, table dropped/purged, etc.) -
Hi,
Has anybody out there used Oracle Trace to monitor the performance of Forte
service objects that access data from Rdb databases. We have been trying to
do this and Trace does not seem to see the Forte servers. Could you please
e-mail me your experiences or any info that you may have in this regard.

Oracle Trace - collection through CLI
This is concerning the collection of database server events through Oracle Trace manual collection utility from Command Line:
1) There is an event called 'LogicalTX Event'. I'm not clear about the items - TX_Type and TX_SO_Addr.
I have an application based on forms/reports which is started through an initial LOGIN screen and then different screens in it can be accessed through the Menu. Once the application starts, there are a lot of SQL statements being called. I'm interested in one particular query for a particular form. The particular query can well be uniquely identified with the cursor_number and other items.
I'm not sure what information this event(LogicalTX) gives to me as it shows just two records - one start record and one end record.
2) In many of the events, there are items as CPU Time, UCPU, and SCPU. UCPU and SCPU are the time spent in CPU in the user and the system mode respectively. What is CPU Time item then? Also, are these in millisecods or are they an indication of the processor cycles?
We have AIX 4.333 and Oracle 8.0.4/8.1.6 installed.The problem has been resolved.
It's something to do with my otrace.cfg file.
I have corrected the file name and regid in this file.
It's working now.
Thanks,

Disable "Oracle Essbase" option in Smartview
Hi,
We are in Planning 11.1.2 application. When users logs-in Smartview, they see two options - "Oracle Hyperion Planning, Fusion Edition" and "Oracle Essbase".... Is there a way to disable "Oracle Essbase" in Smartview?
Thanks,
SivaAs the question is about 11.1.2.x and Smart View then there is a way to disable essbase from the Shared Connection.
Log into workspace > Navigate > Administer > Workspace Server settings
Select enabled products, untick provider services.
Log into a Shared Connection in Smart View and essbase should no longer be there.
This is all or nothing so cannot be applied at user level.
Cheers

What are oracle trace errors?
hi i need to understand what are oracle trace errors? pls help me out.
Hi,
Oracle Trace is a general-purpose event-driven data collection product, which the Oracle server uses to collect performance and resource utilization data, such as SQL parse, execute, and fetch statistics, and wait statistics.
one more thing this is oracle specific information, this forum is for SAP installation related so it is better for you that ask such question on oracle specific forum
regards,
kaushal -
I am not sure if this is the correct place for the topic.
Is there any documentation available which lists down the pros and cons of PECS Vs Oracle Trace. Which is a better solution for performance monitoring?
nullVerify that the product definition file (.fdf) exists and if so, check file protections. Also check directory protections, definition for ORACLE_HOME,
and Oracle Trace parameter settings. If all these are set correctly then verify the input parameter fdf_file.The directory path should NOT be included, only the name of the server event file has to be specified. -

Hi,
I'm using 10g 9.0.4.1.1 and I noticed that every connection by the Oracle user ODS generates a trace file in %ORACLE_ADMIN%\udump.

The trace files become very big in time.
The performance of our portal isn't very good. So I suspect that tracing could be a slowing things down. I don't remember having enabled tracing in any place. And I've looked for Logon triggers but found no such trigger.
Anyone an idea where I could disable the tracing?

hi gurus..
please anybody explain me what is the difference between event based trace (eg 10046,10053) and a normal trace using alter session ?
At what condition it is recommended to use?
is it still using as latest dbms_monitor package is available ?
any help is appreciated.
Thanks in advanceAll 3 are related to monitoring the sql executions and get detailed information about sql, how many current reads,consistent reads etc were needed during the execution of sql.
10053 is more advanced version of 10046 and shows more details like what all execution plans were looked on by optimizer and which plan was finally choosen. The information provided is not plain simple English and hence is mainly used by people doing advanced tuning or by oracle support. -
Disable Oracle Data Guard - Urgent
Hello All,
I am in a peculiar situation and any help is appreciated.
I have a Primay Database and one Physical standby database and they are in Sync. Now, my client wants me to disable data guard and run these two databases as independent one. While performing this activity, there should not be any downtime on Primary. There is no data guard broker involved.
PRIMARY SETUP

How do i make these two databases as independant database without having downtime in PRIMARY. Please help.Hi,
++ First steps will be to defer the remote archiving by setting log_archive_dest_state_2 = defer in primary and then unset all dataguard related parameters on primary and standby like fal_server, fal_client, log_archive_dest_2, log_archive_config.
++ After that perform failover steps on standby to activate it as independent database using the steps mentioned in following link:

Disable HTTP TRACE causes error 413 instead of 501
