Networking And Gateways :: ORA-12535 - TNS / Operation Timed Out
Jan 13, 2013I have two related questions:
Scenario 1:
1. I have two remote Windows machines with database on each. One is Win 2003 Server (machine A) and another one is Win XP (machine B)
2. I can ping from A to B.
3. I can ping from B to A.
4. I can tnsping from A to B.
5. I CAN'T tnsping from B to A.
6. Windows Firewall on both machines are off.
What could be possible reason for point# 5?
Scenario 2:Now, the second part:
1. I had an unwanted entry in tnsnames.ora on B which I removed.
2. Then I restarted the listener on B. Actually, I wanted to restart the one on A to check if that resolves issue mentioned in point# 5 above.
3. I tried tnsping from A to B but suprisingly it is also giving "operation timed out" error now. So now tnsping not working from either sides.
I didn't make any changes in listener.ora on B, just stopped it and started again. Only change made was removing unwanted entry in tnsnames.ora on B.
Why does that affected database connectivity from A to B which was working fine previously?
NOTE: The two machines are connected through VPN using LogMeIn Hamachi. Hamachi assigns it's own IP address to each machine. Machine A is Windows Server 2003 and B is Windows XP.
Networking And Gateways :: TNS-12535 - Operation Timed Out
Jul 26, 2005I have a windows XP server with Oracle 9i on it, when i tried to connect this server from another win XP machine after creating a service. I m getting an error
TNS-12535 TNS:operation timed out
But as i know this error is related to CONNECT_TIMEOUT and it is now obsolete in 9i( am i correct ). I tried it doing from 2 machines but got the same error from everywhere so it means that the problem is with the server.my files are :

Networking And Gateways :: ORA-12535 / TNS / Operation Timed Out
Jan 2, 2013I am trying to connect to a server from a client on another network. I am able to connect just fine if I am on that server, but when I try to connect from a client in my office to the amazon server, I get a timeout message as follows.
ora-12535: TNS:operation timed out.
here is my entry in my local tnsnames.ora file. I believe that the network is wide open between my two computers. o firewalls on the computers and the settings on my cisco allow this to go through. I see the client connect in log files on the server, but it always gets a timeout after 20 seconds.
I have tried to add these parameters to the sqlnet.ora file.

SQL & PL/SQL :: Trigger All DML At All Table Events?
May 4, 2011i want to write, just ONE trigger that handles all DMS events at schema level and writes the field changes to a specific log table. i wanna to write like 'FOR EACH FIELD' as for each row (& also each table). it turns in the fields section and if the 'old' and 'new' values isnt same, it triggers this function & writes changes to log.
ex. is like:
FOR EACH ROW
FOR EACH FIELD
if (old.value != new.value)
insert into LOG(..., old.name,new.name) values (..., old.value, new.value)
NEXT // FIELD
NEXT // ROW
PL/SQL :: Count Sequential Events
Jul 5, 2012I have a table with around half a million rows. I would like to determine how many sequential events occur per device per unique group of events. The requirement is that the events continue to occur within 1 second of each other, every second, with no gaps. For example, in the sample below there is a sequence of 2 events for device 2737, and another sequence of 5 events for device 2737. If there was a 1 second interval with no event (Signal_time) then that would be the end of one group of events, this is also shown below.
Using Oracle 11.2.0.2.0
DEVICE_ID SIGNAL_TIME
4401 17-JUN-12 12.59.59 PM
2332 02-MAY-12 12.59.59 PM
1086 30-MAY-12 12.59.58 PM
2737 17-JUN-12 12.59.58 PM -- start of one group / sequence of events
2737 17-JUN-12 12.59.58 PM -- end of one group / sequence of events
[Code]...
-- start of one group / sequence of events
2737 16-JUN-12 11.59.59 PM
2737 16-JUN-12 11.59.59 PM
2737 17-JUN-12 12.00.00 AM
2737 17-JUN-12 12.00.01 AM
-- end of one group / sequence of events
2737 17-JUN-12 12.00.03 AM
-- this is excluded from the above group of 5 events, but this may be the start of another group
Required output
Device--Count(*)--Start_Signal_Time-----------End_Signal_Time------------Duration (seconds)
2737----5-------------16-JUN-12 11.59.58 PM---17-JUN-12 12.00.01 AM--4

Create Trigger To Stop Events From Being Deleted
Jun 2, 2010I am trying to create a trigger to stop events from being deleted if the date is before the current date. This is the SQL syntax for my table
CREATE TABLE event
(event_id numeric(5) not null,
concert_id numeric(5) not null,
event_date date,
);
What I have attempted so far is:
CREATE OR REPLACE TRIGGER event_deleting
BEFORE DELETE ON event
FOR EACH ROW
BEGIN
IF DELETING THEN

This gives me a few warnings, the first is that a DECLARE is missing and the second is a INTO is missing.

Turning Off Trace On Specific Deadlocks Events?
Jun 17, 2013Can I disable tracing just on deadlocks events on 11gR2?One of our applications provoke several deadlocks. I've warned the developers team several times, but it's taking time to solve it. However, these deadlocks generate trace files of several sizes (from 300M to 3G ..)The Deadlock Graph on them are very useful but the PROCESS STATE section are too long, and until the developers team fix the problem they are just filling up my user dump dest. Can I disable them or disable the PROCESS STATE section from them?
View 2 Replies View RelatedPerformance Tuning :: Digging Out Wait Events
Oct 15, 2013I am using 11.2.0.3.0 version of oracle. As told by the DBAs that two days back the system realised high wait_class i.e 'Application' wait, and its a lot high than regular value as per our system and we need to dig it down, to avoid any future issue. now using below query , i found that the high wait time due to wait class 'Application' is actually belongs to particular event 'SQL*Net break/reset to client', and the sample time was '9 AM' morning.
select time,
round(max(case when event = 'SQL*Net break/reset to client' then time_waited_delta/1e3/decode(total_waits_delta,0,1,nvl(total_waits_delta,1)) end) ,2) SQL_break_reset_client,
round(max(case when event = 'Wait for Table Lock' then time_waited_delta/1e3/decode(total_waits_delta,0,1,nvl(total_waits_delta,1)) end),2) Wait_for_Table_Lock ,
round(max(case when event = 'enq: KO - fast object checkpoint' then
[code]....
Now i want to track it down further to the 'session/sql query/application' level resulting into such high value of wait time. so i queried, dba_hist_ active_ session_history, for the same sample duration (8.30 to 9 am) having event 'SQL*Net break/reset to client', and got two sessions(123,154) and their serial# , but there i got one sql_id(3ahgrey10ogh i.e a 'SELECT' query) specific to one session(123) but for other(125) no sqlid, and also SUM (wait_time + time_waited) is showing '0'.
Then i just removed the sampletime filter from the below query and observed that the same 'same session(123)+session serial#' was activated since 4 days back and was experiencing same waitevent 'SQL*Net break/reset to client', (it was having normal wait event 'db file sequential read' for sometime then after it went for this event ).

TimesTen In-Memory :: Unable To Receive XLA Events After A While?
Mar 12, 2013We have been using XLA to capture events on TimesTen for a while now without any issues. We were on TimesTen 7.0.5 and then moved to 11.2.2.3.0 and now 11.2.2.4.0. The XLA processes used Java 6 64 bit and works well with TimesTen versions 11.2.2.4.0 - 64 bit and 11.2.2.3.0 - 64 bit, without any issues.
However, we recently upgraded to Java 7 64 bit both during build time of our XLA processes as well during runtime. The problem we see now is that XLA process upon startup processes events for a while and then after that doesnt receive any events. The process doesn't throw any errors/exceptions. If we restart the XLA process, all the unprocessed events are received and then it behaves normally for a while after which it fails to receive any further events.
Is there any issue with Java 7 64 bit and the TimesTen XLA API? I read the TimesTen 11.2.2.4.0 manual and it says that Java 7 and the ttjdbc7.jar have been certified to work well. Was just wondering if there were any other issues.
In addition, to debug the problem, we ran XLA on a single node and on a two safe setup. The same observations are noted. On Java 6, the process runs just fine capturing all events without any issues, but with Java 7, the issues persist.
In addition, we are only performing updates/inserts on to TimesTen, no delete actions. The OS on which TimesTen's and XLA runs is Red Hat Enterprise Linux Server release 5.7 (Tikanga).
Trace Events (19027) Generated In Oracle
Aug 31, 2013DB version: 11.2.0.3
I have enabled the below trace event before running query on my session.
ALTER SESSION SET events = '19027 trace name context forever, level 0x1000';ALTER SESSION SET tracefile_identifier = store_trace;
Then I ran my query, and upon the finishing of the query, I ran the below to disable trace.
ALTER SESSION SET events = '19027 trace name context off, level 0x1000';
Now I checked back on the trace folder in my Oracle DB directory structure, but cannot find any file created by using the above set tracefile_identifier. I had previously run the query with "sql_trace" ON with tracefile_identifier, and successfully got the tracefile generated by using the identifier.

View 5 Replies View RelatedPerformance Tuning :: Maximum Wait Events On PX Deq - Execute Reply?
Oct 19, 2010 I have a partitioned table with degree for parallelism defined as 10.
I am getting maximum wait events on PX Deq: Execute Reply.For 2 hours trace the wait event is almost 1.5 hour.
I have done some seraching and i found this.
Quote:
In principle:A parallel query against a partitioned table will use one slave per partition if the query is thought to span multiple partitions, and it can use all slaves on a single partition if the query is thought to target just one partition. Unfortunately, this is NOT strictly true.
It is possible for the optimizer to decide to use parallelism at degree M when accessing N partitions. Sometimes this can lead to very inefficient, brute-force, processing when a more efficient path is available. This can be a particular problem with multi-table joins that should be partition-wise joins. You may be better off leaving the tables defined as non-parallel and adding explicit parallel hints to the code for critical queries.
So i have following questions
1) What is the meaning of PX Deq: Execute Reply.
2) Is this not recommended to use DEGREE clause in Partitioning.
3) Defining DEGREE clause in partioning of table will automatically executes DML on table PARALLELY same a PARALLEL hint clause
