Avoid timeout error in IC through coding

Hi Experts,
I have a requirement to avoid timeout error in interaction centre ,not through RZ* parameters.
but by coding in ICCMP_HEADER, headerviewset.htm.
Has anyone faced this before, can you pls share your ideas.
Highly rewarded.
Regards,
Lakshmi

Hi Lakshmi,
I assume you are referring to the session timeout that is tied to your basis setting. A hidden frame that does a periodic keep alive postback will keep the session alive. If you also have CTI integration, you need to also be sure your CMS is able to keep the communication session alive too.

Hi,
Look at the BSP Page headerviewset.htm. Find the following variable:
"var timeoutValue = <%= cl_crm_ic_services=>get_auto_logout( ) %>"
and
function setTimeoutTimer() that uses the variable
You need to manipulate this variable. Hope this helps.

Select query - timeout error

hi experts,
I have written a pgm where i need to select records from BSAD table. This table has about 10 key fields. But according to my requirement, i can pass only 2 key fields to the table and have to fetch records from this table. But it goes to dump (timout error) in BSAD select query.
So i have used PACKAGE SIZE 20 and tried to fetch only 20 records at a time from the table. But still, it takes lot of time in fetching records from BSAD table.
Pls tell me what is the solution to avoid timeout error and how to fetch the records quickly.
Regards,
Shanthi

I hope that your " two fields" are BUKRS and KUNNR.
Consider this: If I can't supply a value for the first field (after mandt), then the second, etc., the select is going to run FOREVER. I think that, if you used ST05 and explained the BSAD open, you would see the problem. I'm guessing that you're not supplying a value for BUKRS, etc., and thereby causing a full table scan. Or you may have supplied NOT operators in the where clause or included an order by statement. Current ABAP CHECK tools (like SLIN or SCID) should point out problems in the where statement also...
May I suggest utilizing SE11 and looking at BS* tables to see if there is an alternative data source where you can supply an EQ value for the first few fields (at least) of the index? Or, post psuedocode so that the forum users can help you out.

Avoiding concurrency errors when updating a database through AJAX

What are some strategies for avoiding concurrency errors when updating a database through AJAX. That is, in cases where a given user could attempt to modify the same row in the database with simultaneous requests (say, that he updates one column with information with an AJAX call, then immediately submits a form that updates the same row), what are some good ways yo prevent the two updates from colliding? On the JavaScript side one might make the AJAX call synchronous, but I question whether that is the best way to do it. Has anyone else confronted this?

Well, since no one seems to have any ideas so far, I'll throw in my two cents worth.
I'm not too familiar with AJAX so my advice may be limited.
I suggest you do a google search on Optimistic concurrency database to get some ideas on how to handle it.
If your update/insert/delete query is thread safe, then even if the same user double clicks the button fast enough to immediately have another update to the same record, then the first update will complete before the second one is carried out. Therefore no harm is done since he is just updating the same record. Since a typical update/insert/delete takes only a few milliseconds (querying may take a lot more time), its not likely he can click the button that fast. (I assume your using connection pooling for speed).
The trouble comes up when two people call up data from the same record in different browsers. The first one updates/inserts/deletes the record. Now the other user is looking at old data. When he updates/inserts/deletes, there is a problem. One way to handle this is to keep a copy of all the fields from that record in each user's session scope when they first fetch it from the database (example: oldName). Then when you go to update some time later, to this:
sql= update person set name=newValue where personID=3344 and name=oldName
Note oldName is from session scope.
If name in the database has changed, the update will not occur and will return 0 records updated. If it didn't change, it will update.
Note your update function should not throw an exception if it cant update, it should return false. Return true if it worked.
Example: public boolean updateName(String name)
Similiarly, your insert should not throw an exception if the record already exists, it should return false meaning it cant insert.
Exaple: public bolean insertName(String name). Same thing with delete function.
If a record cant be updated due to someone else updating the record while the user was looking at data, return a message that it wasn't updated due to that problem. Then show the user the new value in the database ask him if he wants to overwrite the new change.
Note even if you show 100 records on the JSP, only update the ones that have changed and not all 100. This way, its not likely he has updated the same records someone else has altered. Less likely a colision compared to updating all 100.
If your updating/inserting/deleting more than 1 record (say, 3), then you should look into setting up a transaction in addition to all the above and rolling back all of them if one fails.
Reading the section on databases from http://www.javapractices.com/home/HomeAction.do may also help.

Please help for ORA-02049 - Timeout error

Hi All,
we have got a reporting DB and 14+ Application DBs, the data is extracted from all the application databases (DBs) and dumped into the common tables of reporting database. While inserting and updating the common reporting tables the other jobs gets timeout error and fails. We daily face this failure problem (error: ORA-02049 - Timeout error distributed transaction waiting for lock) for almost 10-15 times.
Can you please help me out in resolving and getting the permanent solution for this problem.
Thanks in advance.

Thanks Kamal,
as mentioned above, I have got Oracle,Java,Unix environment. Autosys jobs are scheduled through out the day.
Mechanism : Autosys job triggers the action at specified time, Unix code calls oracle packaged procedure, extracts data and puts into the common reporting table from this data java code formats the report output.
There are separate reporting jobs for all instances though the report is same but for different locations(14 DB instances).
and all these reporting jobs dump data into common reporting table, data can be differentiated on the hub or location.
But if one job is running for first instance then second job waits for the lock and fails after 2 mins.
I have to avoid this situation, I hold I am able to explain the situation.

Open socket timeout error

Sometime I can write to the local shared variable through data socket. But sometime cannot. Even though, I still can read/write through shared variable monitor.
The error is in the open socket, said connect to peer timeout. I set timeout to 10s or left blank both not work.
I am using 8.2.1 on vista. The computer has 2 lan ports.
I met almost same case long time ago. I solved it by diable NETBIOS and one of the lan port.
This time, I disabled netbios already. But in vista, seems not able to disable the other lan port.
Any suggestion?

Why do i keep getting the "internet connection timeout" error message?

i have been upgrading a few standard itunes albums to itunes plus versions through my 3g mobile broadband connection, while not exactly a fast process, it was working fine until i started to get a backlog of 3 or 4 albums which were waiting in a queue to be downloaded, now every time i do the "check for downloads" option i get the "internet connection timed out" error message...this has been going on for 2 days! am i right in suspecting the backlog of albums is too much for my 3g mobile broadband connection? this is really doing my head in, if any of you techies could help me, it'd be much appreciated...?

yes i have recently updated to itunes 8.2.1, but i am starting to think its apple's servers (i tried to download at my brothers house...different computer and connection...same connection timeout error), because it will still let me download an album, but not necessarily all of the tracks. when i questioned itunes customer services about the seemingly hit and miss state of affairs with downloading, they told me to wait 3 weeks before trying to download the tracks that were giving me the grief (2 tracks from an arctic monkeys album)...which kinda indicates they know there is a problem and are trying to fix it, why else would they say wait 3 wks??? they gave me 5 free music tracks too, which is handy.

Crystal report server2008 (XI R2): CMC session timeout error

HI
Crystal report server2008 (XI R2): CMC session timeout error
Accessing folders, scheduling reporting or running reports are working fine with Central Management Console (CMC) within the Crystal report server or accessing CMC within VPN machine. But when CMC is accessed through browser from client desktop i.e through proxy URL, users are not able to access folder or personal folders to view any reports even admin user is not able to access folders. When users try to access folder or personal folders it gives session-timeout errors. Within less than a 1 or 2 minutes it is showing session timeout error. Appreciates any one help on this quickly.
Regards,
Patrick Raths

Please post your query to the [Business Objects Enterprise Administration|BI Platform; forum. This forum is dedicated to development and deployment of .Net applications that connect and interact with BusinessObjects Enterprise, BusinessObjects Edge, or Crystal Reports Server.

Timeout error in ECC "INTERNAL.CLIENT_RECEIVE_FAILED Error while receiving by HTTP (error code: 402 , error text: ICM_HTTP_TIMEOUT)"

Dear Experts,
I am very critical situation due to this timeout error in ECC, please help me as much as you can. Go-live date is very near, but I am not getting any clue why this error is occurring. our ECC system is EHP 4, and PI is dual stack 7.4
My scenario is synchronous ABAP proxy to HTTP_AAE. request is triggering from ECC via proxy and reaching to third party (bank) through PI, I am reviving the response back in PI from bank. But from PI to ECC the response is not reaching. So in ECC after the defined Timeout limit its getting timed out.
I have tried everything by increasing the timeout in ECC more than 15 minutes in HTTP_TIMEOUT under SXMB_adm in ECC, but nothing worked, even if I am increasing for half an hour then also its getting timeout after half an hour.
response from bank to PI is coming within 30 to 40 seconds, but PI is not sending the response back to ECC.
This is classical scenario, and I have checked the trace via SXMB_Moni in PI as well as in ECC, in ECC its showing the timeout error, but in PI i did not see any trace for this error.
I have read many thread on SCN for the same error, and everywhere it has been suggested to increase the timeout, and I have tired that, it didn't help me.
All ABAP proxy configuration has been done as follows.
RFC destinations in ECC
LCRSAPRFC(TCP/IP)
SAPSLDAPI ((TCP/IP))
G type destination to path "/sap/xi/engine?type=entry"
G type destination SAP_PROXY_ESR to path "/rep"
All the destination connection test is working fine.
but i have a doubt on G type destination(AAE_XDJ) to path "/sap/xi/engine?type=entry" which is returns the status code 500 with message "Empty HTTP request received", is it ok with 500 ?
Configuration in ECC Integration Engine configuration is as follows
Questions
How the message gets pushed to ECC from PI, once the message received in PI, I believe by G type RFC destination on path "/sap/xi/engine?type=entry" , please clarify.
How to trace this, if message is not getting pushed to ECC, I mean I have checked the trace in PI XSMB_MONI, but didn't get anything for this error. In ECC SXMB_moni only I am able to the timeout error.
Please expert help me as soon as you can, this error really effecting me badly in front of management
Thanks,
Farhan

Hi Hareesh,
I configured the scenario based on ICO, and again I received the same timeout error in ECC.
I am really sick with this error, and I have raised the OSS message to SAP. Meanwhile I just want to double check my entire configuration with you. Please see the below configuration (for classical) for ABAP proxy to HTTP_AAE, and let me know if anything is wrong.

Webservice Connection Timeout Error in Sun Java System Application server

I have a java code to connect to Ebay Shopping Webservice that uses the client stub generated through Axis. The code works fine when I run it from the main method of a stand alone Java application. Which means there is no issue with the Proxy settings or any other network setting that could block the webservice from my system. However when I use the same code inside a JSF based Web Application, a connection timeout error comes up. The Web application is deployed on the Sun Java System Application server. The stacktrace of the exception is

The JDK version on my machine is 1.5.0_14. Can somebody point me as where I should be looking for errors?

You need to delete all the files under the 'generated' directory to force the server to recompile them after the JDK upgrade. Also check in domain.xml and make sure the JVM parameter is pointing to the JDK that you have installed. It is also worthwhile to check asenv.conf to see which JDK that file is pointing to as well.

Timeout error (code 6101) for acquisition from MODBUS instrument

I am experiencing a problem which other users have reported, but for which little useful information has been posted:
I am trying to acquire data from an instrument using MODBUS RTU protocol. The code works as desired for a while, but will intermittently stop executing and give a timeout error, code 6101. This code seems to be associated with the MB Serial Master Query sub VI. In the past, I was getting this error as a result of RF noise corrupting the signal in the USB connection to the instrument. Removing the USB cable from the noisy environment eliminated the problem. I am now having the problem with an RS 485 line in the noisy environment, which should be very stable in noisy environemnts.
My question: is there a coding trick i can use to reconnect in the event that a corrupt signal occurrs (or some other problem which results in the intermittent appearence of the error 6101)?   I've increased the timeout value on the MB Serial Master Query sub vi, but this hasn't helped. Any input is appreciated. In case it's useful, I've posted a simple version of code which generates the problem.
Thanks,
Paul

Thanks for your input, Ravens Fan. I am indeed getting a popup error message with the timeout. I agree that putting the MODBUS read in its own loop would solve the problem. However, I'm struggling with trying to figure out how to actually do this.  Should I put the read in a case structure or a while loop? How do I go about looping back to re-execute the read statement? I think so called "state machine architecture" seems to be where I should be going. Some example code would be greatly appreciated.

The timeout setting of all web.config files under infoviewapp, infoviewappactions, platform services, crystal reports folders have been checked and the default timeout 20 minutes is changed to 30 minutes and IIS is restarted, but still users are getting request timeout error within 10 to 15 minutes while running a crystal report. Even admin user.

Please post your query to the [Business Objects Enterprise Administration|BI Platform; forum. This forum is dedicated to development and deployment of .Net applications that connect and interact with BusinessObjects Enterprise, BusinessObjects Edge, or Crystal Reports Server. This includes the development of applications using the BusinessObjects Enterprise, Report Application Server, Report Engine, and Web Services SDKs.
BTW., if thi is an important issue, I'd recommend creating a phone case.
