Tracing the Server and Listener Since the server and the listener use separate configuration files, you must use two different files to invoke tracing for both the server and the listener. Figure 3 - 5. Note : The pump component shares the trace parameters of the Connection Manager, but it generates a separate trace file with the unchangeable default name PMP pid. TRC Note that the trace filenames include process identifiers in hexadecimal notation.
Example 6: Tracing the Navigator Figure 3 - 6 shows the configuration file used and the resulting trace file generated for a Navigator on a system running UNIX.
Figure 3 - 6. Figure 3 - 7. Tracing All Components of an Interchange The trace parameters are set in the tracing pages of the Interchange property sheet in Oracle Network Manager.
The Connection Manager trace file will use the default filename, but the Navigator trace file will be created with a specified name. The trace output is a combination of debugging aids for Oracle specialists and English information for network administrators. Several key events can be seen by analyzing this output from beginning to end: The client describes the outgoing data in the connect descriptor used to contact the server.
An event is received connection request. The connection is refused by the application, which is the listener. ORA is not present. No local communities entry.
Getting local address information Address list being processed No community information so all addresses are "local" Resolving address to use to call destination or next hop Processing address list Call made to destination Processing address list so continuing Getting local community information Looking for local addresses setup by nrigla No addresses in the preferred address list TNSNAV.
If you have a basic understanding of the events the components perform, you can identify the probable cause of an error in the text of the trace. Been using Linux for years and loving it. Glad Oracle jumped on the Linux bandwagon. Faster, more stable, and more friendly Unix IS user friendly, it is just picky as to who it is friends with.
One final food for thought. Two things that came out of Berkley: 1 Unix 2 Acid Concidence??? Have a good weekend. Ok, now my head is starting to hurt. Is it possible for statement 1 to be the parent of statement of number 4?? September 08, - am UTC. Is it posible -- sure. Yes, but it would take a very specific set of actions.
It would take a bit of setup eg: cursor 5 would have been opened and cached previously and we are reusing it and such but it could happen. Cary Milsap's book Optimising Oracle Performance was probably published too late for this discussion thread - but has all the information required to interpret the trace file.
I'm on 8. May 24, - am UTC. Or am I wrong? Does this mean that if this example were run on 10g, we'd see the numbers getting higher, as the open cursors are left cached for possible reuse?
Thanks very much. June 29, - pm UTC. Tom, I'm trying figure it out P", line 12 ORA at line 1 Thank you. August 11, - am UTC. I am thinking of having a feature wherein you can enable trace for a ui page by a flag in the url.
However, since i get a connection from the pool, how do I ensure that at the end of returning the connection back, I set its trace level to the same as it was when it was handed over to me if I change it to start trace for my ui page? August 11, - pm UTC. A reader, August 11, - pm UTC. Ravi, July 21, - am UTC. But it records if a SQL fails pretty well e. Is this a feature? Don't get me wrong, it is not my character to code when-others null. But I am doing a feasibility study to look into all code Forms, Reports to use Raw output to check for any 'invisible' when-others null exceptions.
Cheers Ravi. July 21, - am UTC. A reader, July 26, - am UTC. July 26, - am UTC. A reader, July 27, - am UTC. July 27, - am UTC. There is no "fake error" the select into worked perfectly.
In that case an error should have been returned by SQL? Can these 3 events be put together to assume something bad has happened? July 27, - pm UTC. PLSQL actually failed WHAT plsql? And there were NONE. We can recreate control file from this trace file, if lost the control files. Any one log file from each branch can be used to -- re-create incarnation records.

To check for stored procedures using the Oracle Enterprise Manager console, use the Navigator and the following path:. For Oracle7, Oracle Trace required that these stored procedures be installed on the database. These SQL scripts may be automatically run during database installation depending on the platform-specific installation procedures.
If they are not executed during database installation, you must run these scripts manually. You can add these stored procedures to the database by running the otrcsvr.
To run the script, set the default to the path were the script is located. This script runs other scripts that do not have the path specified. These other scripts fail if you are not in the directory where these scripts will run. LOG file provides information about the collection processing, specifically the Oracle Trace Collection Services errors.
LOG file is created in the current default directory. Oracle Enterprise Manager Messages Manual for general information about causes and actions for most Oracle Trace messages. Oracle Server releases 7. Prior to Oracle Server releases 7. If you must manually execute otrcfmtc.
The otrcfmtc. See Also : Table for a description of the server event sets. Note: The collection name is also used to form the collection name. Note: Older versions of the Oracle server, back to release 7. Note: For better readability, the layout of this regid string has been simplified. Note : For Oracle server releases 7. Note: Because there are incompatibilities between at least some versions of the formatter tables, use a separate database schema for each version of the Oracle Trace formatter.
Note: In this version of Oracle Trace, the term "facility" has been changed to "product". Note: Prior to Oracle Server release 8. Note: The following tables use Oracle7 Server names for example purposes.
Note: The text in the Operation item is equivalent to information about the execution plan, which is similar to data that can be obtained by running explain plan. See Also: "Event Sets". All Rights Reserved. Book List. Master Index. Note: Oracle Trace will be deprecated in a future release. Sets report width, such as -w The default is 80 characters. Sets the number of report lines for each page.
The default is 63 lines for each page. Suppresses all event and item report headers, producing a shorter report. Session migration between shared server processes.
The first time a database command is performed that may change the database status. Event marking a definite change in database status. Generic WAIT event. Context is provided in the event strings. Number of times file system performed input. Number of times file system performed output. Indicates if a transaction committed or aborted. Number of cursor associated with SQL statement.
Recursive level at which SQL statement is processed. Depends upon event in which it occurs for example, wait event description. Flag set if data retrieved is last data from query. Address of SQL statement in library cache.
Flag set if SQL statement was missing in library cache. Position of the operation within the execution plan for a statement. The definition of P1 depends upon the event in which it occurs. The definition of P2 depends upon the event in which it occurs. The definition of P3 depends upon the event in which it occurs. The definition of P4 depends upon the event in which it occurs. The definition of P5 depends upon the event in which it occurs.
The definition of P6 depends upon the event in which it occurs. The definition of P7 depends upon the event in which it occurs. The definition of P8 depends upon the event in which it occurs. The definition of P9 depends upon the event in which it occurs. The definition of P10 depends upon the event in which it occurs. Position within events having same parent operation. The address of the transaction state object. Elapsed time, in hundredths of seconds, for the wait event.
