PECS Vs Oracle Trace

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?
null

Verify 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.

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.

Oracle trace

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.

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.)

Forte and Oracle Trace

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,

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

Oracle trace on events

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 advance

All 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.

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;

Oracle Trace File generation for a session

Hi,
I am using oracle 10g(10.2.0.5) in RHEL5 server. i have used the exec dbms_system.set_sql_trace_in_session(147,3,TRUE); statement to trace a particular session. i am able to trace successfully but i have created a new table in that session where i am not able to find any create table statement in the generated trace file but i can find the insert statements which i performed on the newly created table in the trace file.
Does DDL statements not recorded in the trace events???

Gather Schema Statistics produces HUGE oracle trace file

Hi
I am running gather schema stats on my E-Biz 12.1.3 / 11.2.0.3 system
Each week we run Gather Schema Stats
I have noticed that when the job completes a 3g trace fuile is produced under the Oracle RDBMS home
I have tried un-checking the box when the COnc Request is submitted to DO NOT SAVE OUTPUT FILE but it is still procuced.
I dont want it and do not understand why it is produced. Anyone out there have a resolution?

I have noticed that when the job completes a 3g trace fuile is produced under the Oracle RDBMS homeWhat is the file name/location? What is the contents of this trace file?
I have tried un-checking the box when the COnc Request is submitted to DO NOT SAVE OUTPUT FILE but it is still procuced.Do you have any debug/trace enabled on HRMS schema?
I dont want it and do not understand why it is produced. Anyone out there have a resolution?Was this working before? If yes, any changes been done since then?
What are the parameters you use to run "Gather Schema Statistics" concurrent program?
Thanks,

Missing Oracle trace file

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.

Oracle trace file

Hi What is the diffrence between following 2 statements
1...SQL> alter system set max_dump_file_size=2000m;
alter system set max_dump_file_size=2000m
ERROR at line 1:
ORA-02065: illegal option for ALTER SYSTEM
2...SQL> alter system set max_dump_file_size=2000M;
System altered.
what is the difference between 2 statements does it alteres operating system blocks in statement 2. I need to conform it

it seems to be case sensitive, check the reference:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/initparams129.htm#CHDIABEI
instead of 2000M I would write 2G.
it doesn't alter any blocks it defined an upper limit for a trace file.

Bind values for complex datatype in Oracle trace file

If I run trace on oracle spatial queries, how can I get the detailed information of the bind variable value for sdo_geometry objects (the content of the sdo_geometry objects, e.g. coordinates... ) in the queries?
For example, in the query, SRID, SDO_ELEM_INFO_ARRAY, and SDO_ORDINATE_ARRAY are bind variables. For SRID, I can find its value (number), but for sdo_elem_info_array and sdo_ordinate_array, I only got something like:
BINDS #1:
bind 0: dty=23 mxl=32(16) mal=00 scl=00 pre=00 oacflg=00 oacfl2=0 size=32 offset=0
bfp=0c0521dc bln=32 avl=16 flg=05
value=

C0521E0 479F3EB7 8B3F2BA9 A1441E4C [.>.G.+?.L.D.]
I also tried to look at v$sql, v$sql_bind_data, v$sql_bind_capture views and haven't been able to find the values.
Thanks!

Oid and Oracle trace

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 content of such a trace file is something like this:
PARSING IN CURSOR #1 len=35 dep=0 uid=49 oct=42 lid=49 tim=84640000 hv=2368804601 ad='663a6d4c'

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?
regards,
Ivan
