PRVF-5636 : The DNS response time for an unreachable node exceeded "15000" ms on following nodes
HI
I received this error message when i was trying to install 10g software on oracle linux 5.632 bit machine . how to resolve this issues
Checking consistency of file "/etc/resolv.conf" across nodes
Checking the file "/etc/resolv.conf" to make sure only one of domain and search entries is defined

PRVF-5636 : The DNS response time for an unreachable node exceeded "15000"
Friends,
OS: OEL 6.3 64 bit
DB: 11.2.0.3
Environment: VirtualBox 4.1.20
i have 3 nodes. one is for dns and other two for rac1 and rac2
i have done all the preliminary steps. then i started
[oracle@rac1 grid]$ ./runcluvfy.sh stage -pre crsinst -n rac1,rac2 -verboseand all are passed except the above subjected error.

Strange response time for an RFC call viewed from STAD on R/3 4.7
Hello,
On our R/3 4.7 production system, we have a lot of external RFC calls to execute an abap module function. There are 70 000 of these calls per day.
The mean response time for this RFC call is 35 ms.
Some times a few of them (maybe 10 to 20 per day) are way much longer.
I am currently analysing with STAD one of these long calls which lasted 10 seconds !
Here is the info from STAD
Response time : 10 683 ms
Total time in workprocess : 10 683 ms
CPU time : 0 ms
RFC+CPIC time : 0 ms
Wait for work process 0 ms
Processing time 10.679 ms
Load time 1 ms
Generating time 0 ms
Roll (in) time 0 ms
Database request time 3 ms
Enqueue time 0 ms
Number Roll ins 0
Roll outs 0
Enqueues 0
Load time Program 1 ms
Screen 0 ms
CUA interf. 0 ms
Roll time Out 0 ms
In 0 ms
Wait 0 ms
Frontend No.roundtrips 0
GUI time 0 ms
Net time 0 ms
There is nearly no abap processing in the function module.
I really don't uderstand what is this 10 679 ms processing time especially with 0 ms cpu time and 0 ms wait time.
A usual fast RFC call gives this data
23 ms response time
16 ms cpu time
14 ms processing time
1 ms load time
8 ms Database request time
Does anybody have an idea of what is the system doing during the 10 seconds processing time ?
Regards,
OlivierHi Graham,
Thank you for your input and thoughts.
I will have to investigate on RZ23N and RZ21 because I'm not used to use them.
I'm used to investigate performance problems with ST03 and STAD.
My system is R/3 4.7 WAS 6.20. ABAP and BASIS 43
Kernel 6.40 patch level 109
We know these are old patch levels but we are not allowed to stop this system for upgrade "if it's not broken" as it is used 7/7 24/24.
I'm nearlly sure that the problem is not an RFC issue because I've found other slow dialog steps for web service calls and even for a SAPSYS technical dialog step of type <no buffer>. (what is this ?)
This SAPSYS dialog step has the following data :
User : SAPSYS
Task type : B
Program : <no buffer>
CPU time 0 ms
RFC+CPIC time 0 ms
Total time in workprocs 5.490 ms
Response time 5.490 ms
Wait for work process 0 ms
Processing time 5.489 ms
Load time 0 ms
Generating time 0 ms
Roll (in+wait) time 0 ms
Database request time 1 ms ( 3 Database requests)
Enqueue time 0 ms
All hundreds of other SAPSYS <no buffer> steps have a less than 5 ms response time.
It looks like the system was frozen during 5 seconds...
Here are some extracts from STAD of another case from last saturday.

I'm thinking also now about the message server as there is load balancing for each RFC call ?

How to obtain the Query Response Time of a query?
Given the Average Length of Row of tables and the number of rows in each table,
is there a way we get the query response time of a query involving
those tables. Query includes joins as well.
For example, suppose there 3 tables t1, t2, t3. I wish to obtain the
time it takes for the following query:
Query
SELECT t1.col1, t2.col2
FROM t1, t2, t3
WHERE t1.col1 = t2.col2
AND t1.col2 IN ('a', 'c', 'd')
AND t2.col1 = t3.col2
AND t2.col1 = t1.col1 (+)
ORDER BY t1.col1
Given are:
Average Row Length of t1 = 200 bytes
Average Row Length of t2 = 100 bytes
Average Row Length of t3 = 500 bytes
No of rows in t1 = 100
No of rows in t2 = 1000
No of rows in t3 = 500
What is required is the 'query response time' for the said query.I do not know how to do it myself. But if you are running Oracle 10g, I believe that there is a new tool called: SQL Tuning Advisor which might be able to help.
Here are some links I found doing a google search, and it looks like it might meet your needs and even give you more information on how to improve your code.

How to find the Response time for a particular Transaction
Hello Experts,
Am implementing a BAdI to achieve some customer enhancement for XD01 Transaction . I need to confirm to customer that after the implementation and before implementation what is the response time of the system
Response time BEFORE BAdI Implementation
Response time AFTER BAdI Implementation
Where can i get this.
Help me in this regard
Best Regards
SRiNiHello,
Within STAD, enter the time range that the user was executing the transaction within as well as the user name. The time field indicates the time when the transaction would have ended. STAD adds some extra time on using your time interval. Depending on how long the transaction ran, you can set the length you want it to display. This means that if it is set to 10, STAD will display statistical records from transactions that ended within that 10 minute period.
The selection screen also gives you a few options for display mode.
- Show all statistic records, sorted by star
This shows you all of the transaction steps, but they are not grouped in any way.
-Show all records, grouped by business transaction
This shows the transaction steps grouped by transaction ID (shown in the record as Trans. ID). The times are not cumulative. They are the times for each individual step.
-Show Business Transaction Tots
This shows the transaction steps grouped by transaction ID. However, instead of just listing them you can drill from the top level down. The top level will show you the overall response time, and as you drill down, you can get to the overall response time.
Note that you also need to add the user into the selection criteria. Everything else you can leave alone in this case.
Once you have the records displayed, you can double click them to get a detailed record. This will show you the following:
- Breakdown of response time (wait for work process, processing time, load time, generating time, roll time, DB time, enqueue time). This makes STAD a great place to start for performance analysis as you will then know whether you will need to look at SQL, processing, or any other component of response time first.
- Stats on the data selected within the execution
- Memory utilization of the transaction
- RFCs executed (including the calling time and remote execution time - very useful with performance analysis of interfaces)
- Much more.
As this chain of comments has previously indicated, you are best off using STAD if you want an accurate indication of response time. The ST12 (combines SE30 ABAP trace and ST05 SQL trace) trace times are less accurate that the values you get from ST12. I am not discounting the value of ST12 by any means. This is a very powerful tool to help you tune your transactions.
I hope this information is helpful!

All,
I am in a predicament with internet browsing speeds...We have a 3rd party look after our line and internet facing f/w so I cant troubleshoot them, so at the moment Im looking at ISA as the potential bottleneck - we have a fairly standard environment:
Internal > Local Host > Perimiter n/work > Firewall > Internet
I have been running custom reports on the ISA server to see what data can be collected - I have noticed that "Average response time for non cached requests" (traffic by time of day) can be as high as 76 seconds!!!!!! Cached hits are between .5
and 2 seconds.
I have also coonfigured a connectivity verifier which is also flagging slow connectivity, massively over the >5000ms and also reporting "cant resolve server name on occassions- and this is configured for
www.Microsoft.com --- DNS ???!?!, however I have looked through DNS (no obvious errors / config issues) which I can see
I have run the BPA on ISA server to ensure its Health - - connectivity verifier errors flagged timeouts to microsoft.com as expected...
Can anyone advise any obvious areas to investigate as Im struggling! - as always the 3rd party have told us the internet pipe is fine :OProblem resolved.
DNS forwarders have been changed on the ISA server / DNS and this has improved lookup speed considerably.
thanks all :) -
Response time for Error Messages - Please Help
Hi
I have a PRO C application talking to an Oracle database.
The Response time for successful query is within desirable limits.
But when there is a error condition (eg SQLError -3113,or connection refused) it takes more than 9 minutes for the database to respond with the error code.
This condition is observed with only one database while the others are working fine.
What is the reason for this? Can’t it be reduced?
Regards
Davidever been faced with the same problem ?
Why deleting ? It that only one way to fix this problem ?
What are the others doing in such cases. Or am I the only one person
where has this special problem on the world. Becides I dont believe
in solving the problem through removing mentioned directory and
reinstalling. Nevertheless I will try it. I let you know about the result.

Report to calculate avg response time for a transaction using ST03.
Hi Abap Gurus ,
I want to develop a report which calculates the average response time(ST 03) for a transaction on hourly basis.
I have read many threads like in which users are posting which tables/FM to use to extract data such as dialog step and total response time .
I am sure many would have created a report like this , would appeciate if you can share pseudo code for same.Any help regarding the same is highly appreciated...

Help required in optimizing the query response time
Hi,
I am working on a application which uses a jdbc thin client. My requirement is to select all the table rows in one table and use the column values to select data in another table in another database.
The first table can have maximum of 6 million rows but the second table rows will be around 9000.
My first query is returning within 30-40 milliseconds when the table is having 200000 rows. But when I am iterating the result set and query the second table the query is taking around 4 millisecond for each query.
the second query selection criteria is to find the value in the range .
for example my_table ( varchar2 column1, varchar2 start_range, varchar2 end_range);
My first query returns a result which then will be used to select using the following query
select column1 from my_table where start_range < my_value and end_range> my_value;
I have created an index on start_range and end_range. this query is taking around 4 millisseconds which I think is too much.
I am using a preparedStatement for the second query loop.
Can some one suggest me how I can improve the query response time?
Regards,
ShyamTry the code below.
Pre-requistee: you should know how to pass ARRAY objects to oracle and receive resultsets from java. There are 1000s of samples available on net.
I have written a sample db code for the same interraction.
Procedure get_list takes a array input from java and returns the record set back to java. You can change the tablenames and the creteria.
Good luck.
DROP TYPE idlist;
CREATE OR REPLACE TYPE idlist AS TABLE OF NUMBER;
CREATE OR REPLACE PACKAGE mypkg1
AS
PROCEDURE get_list (myval_list idlist, orefcur OUT sys_refcursor);
END mypkg1;
CREATE OR REPLACE PACKAGE BODY mypkg1
AS
PROCEDURE get_list (myval_list idlist, orefcur OUT sys_refcursor)
AS
ctr NUMBER;
BEGIN
DBMS_OUTPUT.put_line (myval_list.COUNT);
FOR x IN (SELECT object_name, object_id, myvalue
FROM user_objects a,
(SELECT myval_list (ROWNUM + 1) myvalue
FROM TABLE (myval_list)) b
WHERE a.object_id < b.myvalue)
LOOP
DBMS_OUTPUT.put_line ( x.object_name
|| ' - '
|| x.object_id
|| ' - '
|| x.myvalue
END LOOP;
END;
END mypkg1;
[pre]
Testing the code above. Make sure dbms output is ON.
[pre]
DECLARE
a idlist;
refc sys_refcursor;
c number;
BEGIN
SELECT x.nu
BULK COLLECT INTO a
FROM (SELECT 5000 nu
FROM DUAL) x;
mypkg1.get_list (a, refc);
END;

Significant difference in response times for same query running on Windows client vs database server
I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
Ideally I would like to get a response time equivalent on the Windows client to what I get when running this on the database server.
In both cases the query plans are the same.
The query and plan is shown below :
{code}
SQL> explain plan
2 set statement_id = 'SLOW'
3 for
4 SELECT DISTINCT /*+ FIRST_ROWS(503) */ objecttype.id_object
5 FROM documents objecttype WHERE objecttype.id_type_definition = 'duotA9'
6 ;
Explained.
SQL> select * from table(dbms_xplan.display('PLAN_TABLE','SLOW','TYPICAL'));
PLAN_TABLE_OUTPUT
| Id | Operation | Name | Rows | Bytes |TempSpc| Cost (%CPU)|
| 0 | SELECT STATEMENT | | 2852K| 46M| | 69851 (1)|
| 1 | HASH UNIQUE | | 2852K| 46M| 153M| 69851 (1)|
|* 2 | TABLE ACCESS FULL| DOCUMENTS | 2852K| 46M| | 54063 (1)|
{code}
Are there are configuration changes that can be done on the Oracle client or database to improve the response times for the query when it is running from the client?
The version on the database server is 10.2.0.1.0
The version of the oracle client is also 10.2.0.1.0
I am happy to provide any further information if required.
Thank you in advance.I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
There are NO queries that 'run' on a client. Queries ALWAYS run within the database server.
A client can choose when to FETCH query results. In sql developer (or toad) I can choose to get 10 rows at a time. Until I choose to get the next set of 10 rows NO rows will be returned from the server to the client; That query might NEVER complete.
You may get the same results depending on the client you are using. Post your question in a forum for whatever client you are using. -
SLR - transaction response time for all appl. servers together
Hi,
we want to have in SLR response time for defined transaction. We have activated necessary steps for monitoring transactions, started CPH and we can see in SLR average response times.
We have several application servers and we want to have in SLR TOTAL response time for all appl. servers together.
Is it possible? What is necessary steps to do it?
Thanks for all hints.
Regards,
RomanHi Andreas,
Another way to approach this would be to use CCMS transaction monitoring by maintaining table ALTRAMONI (in the satellite system) as described here: http://help.sap.com/saphelp_nw70/helpdata/en/b3/468e3b093d4031e10000000a11402f/content.htm
In RZ20 you'll be able to see the last 24 hours of performance data in a 1-hour granularity, as well as the last 30 minutes in a higher granularity. Depending on your requirements you can then configure alerting so that you get an email when performance passes a certain threshold.

Session manager is taking 10% of the total response time
Hi
As per our recent analyses session manager is taking around
10% of the total response time, we have done the archiving of data
however it still taking around 9% of the total response time, I have checked few notes from service market place. However i would request you to suggest something

Average Response Times for a Reports Server
On Application Server Control and Grid Control are sections listing the Average Response Time in milliseconds.
Can anyone tell me what response it is measuring exactly?
Thanks

On our R/3 ECC6 production system ,we have one aRFC call by external system,there are 200000 times per day.
and the response time for the RFC call is 35ms ,Some times its response time(commit time) are much longer and up to 2 seconds.
There is very simple code for the RFC as shown below
insert ztable from table lt_internal_table.
commit work
call function 'function_name'
starting new task 'N'.
tables
it_tab = lt_internal_table.
Regards,
ShiChunQingDear Randorlf ,
Now i can determine that statement "commit work" have a high cost some times.
I write a simple report as show below,
One high cost will occurs per several minutes.
report ztest.
do 10 times.
GET RUN TIME FIELD t1.
INSERT ytest_table FROM TABLE lt_tab.
GET RUN TIME FIELD t2.
t1 = t2 - t1.
WRITE:/ 'insert:',t1,sy-uzeit.
COMMIT WORK.
GET RUN TIME FIELD t3.
t2 = t3 - t2.
WRITE: 'commit:',t2,sy-uzeit.
enddo.
Run results:
insert: 879 16:23:02 commit: 1,713 16:23:02
insert: 1,607 16:23:05 commit: 4,434 16:23:05
insert: 1,265 16:23:08 commit: 3,790 16:23:08
insert: 648 16:23:11 commit: 1,195 16:23:11
insert: 659 16:23:14 commit: 390,208 16:23:15
