Oracle - Informatica transfer speed fetch size and SQL*Net message from c
Hi,
I'm testing how fast informatica can take data from our 10.2.0.3 and using large (140GB 1 200 000 000 rows) table as source and doing simple
select * from large_table .
Here goes quite interesting wait time analyze :) .
call count cpu elapsed disk query current rows

gc cr grant 2-way 67 0.00 0.03The interesting part is ' SQL*Net message from client 186994 0.21 478.74'
so looks like from Informaticka point of view (client side) is lagging 478 sec , so its lagging .
Doing some math 25431184/186994 = 136 .
Could You share with me Your experience in that matter ?
Looks like to speed up I need to :
1. increase fetch size (not sure how to do that).
2. increase SDU client and probably server side .
Network is 100Mbit ethernet so about 10MBytes per second .

Have you solve your problem ?
If yes I'm strongly interest by the solution.
If you have a question of issue create your own thread and provide the particulars of your use case. This thread is year old.
OP likely did NOT have any problem. As OP stated the max throughput for a 100 Mbit network is about 10 MB per second. So do the math for moving 140 GB and you will see that the network itself will be the limiting factor.

How to drill down the cause of "SQL*Net message from/to client"
Pretty frustrated with my tune up using suggestions from many papers for Oracle 10g R2 on AIX 5.3 L system. My users told me that the system (including Baan 5c) still responds slowly in some processes, some even worsen.
Using both queries such as
SELECT sid, schemaname, status FROM gv$session ORDER BY 2;
SELECT inst_id, seq#, event, p1, p2, p3, wait_time FROM v$session_wait_history WHERE sid=<sid from above>
INST_ID SEQ# EVENT P1 P2 P3 WAIT_TIME
1 1 SQL*Net message from client 1413697536 1 0 6419
1 2 SQL*Net message to client 1413697536 1 0 0
and others similar, I found very large numbers (almost 97%) of the sessions have events as “SQL*Net message to client” and “SQL*Net message from client” on their wait_time even the sids are in inactive status. After checking the meaning of those messages in Oracle Performance and Tuning document, the document states that mainly they are probably network problems. So How can I drill down to what status of network from my client (the users) to server by Oracle or AIX? In Baan, it has its own parameter sets in its db_resource file controlling the connectivity. In average, there are 4000 “opened cursor current”, but most of them inactives.
So my colleague asked me rollback all th changes I did on OS level such as minperm%=5
maxperm%=90
maxclient%=90,
lgpg_regions lgpg_size,
sys0 maxuproc=512,
aio0 maxservers='260'
and many ioo parameters to system defaults.
I even removed the mulitplex copy of the redo log.
I tried to proof them that there maybe the problem of the Baan/Oracle connectivity, ie due to message above,http://docs.oracle.com ... read them for configuration information.
http://tahiti.oracle.com ... read them for recommendations.
http://otn.oracle.com ... find the best practices docs.
http://metalink.oracle.com ... look for similar issues to yours.
People that change things, on production boxes, without first determining that metrics indicate they are a good idea, and then determining their impact on a test box, should be sold to zoos as leopard food.
PS: Slowly likely has absolutely nothing to do with anything you touched. First you tune the application. Then you tune the database. Then you tune the operating system. Get out of the way and make the DBAs do their job. -
SQL*Net message from client - huge wait in trace file
Dear All,
I am facing a performance issue in a particular operation ( which was completed in 21 Minutes earlier). Now the same operation takes more than 35 Minutes. I took a trace for those session ( 10046 level 12 trace ) and found Lot of waits in SQL*Net message from client.
Elapsed times include waiting on following events:
Event waited on Times Max. Wait Total Waited
---------------------------------------- Waited ---------- ------------
SQLNet message from client 611927 10.00 1121.35*
I copied only the highest wait in the tkprof output.
And I found from the tkprof and even in raw trace file this event waits more time after excuting
SELECT sysdate AS SERVERDATE from dual;
Elapsed times include waiting on following events:
Event waited on Times Max. Wait Total Waited
---------------------------------------- Waited ---------- ------------
SQL*Net message to client 115 0.00 0.00
SQLNet message from client 115 10.00 724.52*
Please help me to find out why this wait taking long time, especially on the above query..

In awr report , this query taken less than a sec for more than 2000 executions.
Regards,
VinodhGood idea to check the raw trace file. It is important to notice that this particular wait event appears after the fetch of the result from the database. The client receives the SYSDATE from the database server, and then the client performs some sort of action for about 10 seconds before submitting its next request to the database. The SQL statement that immediately follows and immediately preceeds this section of the trace file might provide clues regarding what caused the delay, and where that delay resides in the client side code. Maybe a creative developer added a "sleep for 10 seconds" routine when intending to sleep for 10ms? Maybe the client CPU is close to 100% utilization?

Process wait SQL*Net message from dblink /SQL*Net message from client
Hi There,
We have an ETL process that we kindly need your help with. The process been running since Sun, where it transfers the data from one server (via remote query). The process was running ok till last night where it appeared
to have stopped working and/or the session is just idling doing nothing.
Here are some tests that we did to figure out what's going on:
1. when looking at the session IO, we noticed that it's not changing:

listener.ora:
INBOUND_CONNECT_TIMEOUT_LISTENER = 6000What else can we do and/or further investigate to work out the root cause of the problem, and may be help resolve this. We don't want to just stop and start the process again as it took few days already. We have
had a chat to the infrastructure team and they've assured us that there have been no network outages.
Also, the alert logs for both instances (local and remote) shows no errors what so ever!
Your input is highly appreciated.

Hi all,
This is my first post here. I will try to more less describe the problem i am facing.

Do you have an option for block all incoming message and request EXCEPTED messages from my contacts?
Please help!!To whom it may concernDear Madam/Sir who works for Skype & Microsoft Dear all who can really help, Do you have an option for block all incoming message and request EXCEPTED messages from my contacts? or Do you have any solution to solve my problem from begin to now in present time? Even though, I set the Privacy settings: - Allow calls from... "people in my Contact list only"- Automatically received video and share screens with "people in my Contact list only"- Allow IMs from "people in my Contact list only" I still received unknow users sent me messages in every day, contact requests etc. And they're all clearly spammings and identity thefts. I only wanna contact with my family and my freinds here with Skype via my Windows device and my mobile phone (w/Android OS). And this is the only way to contact with them, because they could use Skype only in overseas. BUT I don't need new friend from other unknow Skype member. I keep blocked all unknow spammers in every day. However in this morning, I feel so scared with Skype on my mobile, I looked at my mobile Skype, I saw it automatically showed me the list of all blocked members. BUT they were all unblocked (contact unblocked) by my mobile (Android version) Skype itself automatically, and listed them one by one on the screen, and about 30 seconds later, they all were disappeared suddenly. I don't know what do to now, is it indicating my account was hacked?And how could I found out all those members again and block them again and delete all of them for ever? I appreciate if you would improve the privacy protection. Thank you very very very much.
Hrm... that may be true and this may be a function of the phone email client that Apple just doesn't do.
No, I can easily MANUALLY delete the messages. I would prefer if I didn't have to do it twice, tho. Once on the mail server and once on the phone.
What I think the phone needs to do is, when it checks the POP, anything NOT there should be removed locally. I think you are correct on POP; the phone will poll the mx (mail exchanger) and the mx will pass off the messages to the phone. The phone then keeps ALL of that unitl you manually delete it.
If, say, I remove a message from the mx, I would like the phone, when next polls, to see that that particular message isn't on the server anymore and remove it locally.
Perhaps it's just me but if I delete the message on the mx itself, via my ISP's webmail interface, I really don't want to have to remove it again from my phone.
thxs!
cheers

I have been receiving messages from this sender fine and then all of a sudden for some reason there was a do not enter sign beside her name. I didn't know how or why it got there, some button got bumped or the mouse, and I didn't know how to take it off so I just left it. Since then, thunderbird has been reopened and all messages that I had received have disappeared and no new messages from this sender appear even though I know she has sent them to me. I have checked into filters and I have none set so it is not that. I can't figure out how the do not enter sign got beside the contact, but I'm sure it's the reason for my problems and I don't know how to fix it. Thanks

How do I backup and view text messages from my iphone 4?
How do I backup and view text messages from my iphone 4? I want to know where and how to backup and view text messages and all other personal files, including voicemail, recent calls, etc. from my iphone. Is this function in iTunes and/or does iTunes already backup this stuff when I sync?
I really just want the answer to how and where this works.
ThanksApple provides functionality in the backup done via iTunes to backup the device and text messages. There is no functionality to view the text messages on the computer.
About iOS backups
Other programs are available which can extract text messages from the device or the iTunes created backup and then be viewed on the computer. To my knowledge, no program exists which can force backed up text messages into the device once they've been removed.

How can I send and receive a message from a queue using standalone program
Hi,
I want to write a standalone Java program which has to post a message to a queue and receive a message from a queue thats specified as a replyto queue.I want to have my application to be completely standalone without the need of a Application server.What all the Jars do I need to include in the application.My aim is to have the application standalone and portable so that the application runs on any machine that has a JRE.
Thanks in advance,
PrathimaHi,
You can get quite simple standalone MQ Java programs from this site http://www.capitalware.biz/mq_code_java.html.
Also regarding the jars required for your application depends on the API being used. If you use MQI API few jars are required and if you decide to use JMS API you'll require few other jars. But you got to either install Websphere MQ Java Client, which will copy the jars to the respective location, or you can choose to copy the jars from some other machine manually.
Eventually, all the jars related to MQI and JMS API will reside under /usr/mqm/java/lib/ or /var/mqm/java/lib/ UNIX Environment. And in case of WINTEL, you should find the jars under C:\Program Files\IBM\WebSphere MQ\Java\lib.
Trust it clarifies...
