Performance using Generic Sync

Hey Guys,
i am facing a problem. Syncronization using MI installed on my laptop takes 3667 ms, but starting a sync from my pda takes 95425 seconds.
it is only the time sm.synchronizeWithBackend(); needs until the inboundprocesshandler starts working.
i am using windows mobile 5 and 6 and the connection is made using a usb cable and active sync
what can i do. the sync transfers only very little data, just some strings to get information about a workarea.

Hi Philipp,
Sync from PDA will definitely take more time (3 to 4 times depends on data) than one a laptop. You can't compare both as the processing power & memory of a PDA is too inferior compared to laptop.
For your problem, Check that this is not an isolated incident. Do test multiple times (min 3) and try to get a common time. Also do a statistical record check (Tcode: STAD) in the Middleware server for both laptop and client syncs and see the timings are the same.
Enable trace level to ALL in the PDA and check the trace for any errors. Also that will give you the time for downloading the data and persisting the data.

Poor Performance using Generic Conectivity for ODBC

Hi my friends.
I have a problem usign Generic Conectivity , I need update 500,000 records in MS SQL Server 2005, I'm using Generic Conectivity for ODBC. In my Oracle Database i have create a DB_LINK called TEST to redirect to MS SQL Server database.
Oracle Database: 10.2.0.4
MS SQL Server version: 2005
The time for update 1,000 records in MS SQL Server using DBMS_HS_PASSTHROUGH is ten minutes. This is a poor performance.
This is de PL/SQL
DECLARE
c INTEGER;
nr INTEGER;
CURSOR c_TEST
IS
SELECT "x", "y"
FROM TEST_cab
WHERE ROWNUM <= 1000
ORDER BY "y";
BEGIN
FOR cur IN c_TEST
LOOP
c := DBMS_HS_PASSTHROUGH.OPEN_CURSOR@TEST;
DBMS_HS_PASSTHROUGH.PARSE@TEST(
c,
'UPDATE sf_TEST_sql
SET observation= ?
WHERE department_id = ?
AND employee_id = ? ');
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@TEST (c, 1, 'S');
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@TEST (c, 2, 'N');
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@TEST (c, 3, 'ELABORADO');
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@TEST (c, 4, 'PENDIENTE');
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@TEST (c, 5, cur."x");
DBMS_HS_PASSTHROUGH.BIND_VARIABLE@TEST (c, 6, cur."y");
nr := DBMS_HS_PASSTHROUGH.EXECUTE_NON_QUERY@TEST (c);
DBMS_HS_PASSTHROUGH.CLOSE_CURSOR@TEST (c);
COMMIT;
END LOOP;
END;
You can help, how better the performance for update 500,000 record by record in MS SQL Server. I need advantages of use Oracle Transparent Gateway for Microsoft SQL Server.
your's can suggest my another solution ?
Thanks.

Hi,
There are no real parameters to tune the gateways. You should turn on gateway debug tracing and check the SQL that is being sent to SQL*Server to make sure is update statements and nothing else.
If this is the case then the time taken will be down to various factors, such as network delays, processing on SQL*Server and so on.
How long does it take to update the same number of records directly on SQL*Server without the Oracle or the gateway involved or if you use another non-Oracle client to do the same updates across a network, if a network is involved ?
It may be possible to improve performance by changing the HS_RPC_FETCH_REBLOCKING parameter, so have a look at this note in My Oracle Support -
Tuning Generic Connectivity And Gateways (Doc ID 230543.1)

How to see the data in data containers when working on Generic Sync ?

Hi All,
I am working on Mobile Sales For HandHeld Generic Sync based application. To check the data transafer from Mi Client > MI server> CRM backend, we are using Generic Sync Queue Monitor in NWA. But how to check the actual dara in data containers showed on the monitor? Any specific transaction ( e.g. merep_mon for smart sync) to chk the same?
Thanks & regards,
Rucha Atre

Hi,
This is a tedious process of viewing the data in the containers since there is no tool to monitor the same. The data sent from the client is stored MESYHEAD and MESYBODY. Once the entire processing is completed then the entries from this table is deleted. If the processing has failed or not taken place then the entries will in this table.
Data Containers will name value pairs with field name and data in the data field. This table will also contain data from smart sync applications.
Thanks..

Using LGWR SYNC with Max Performance

Hi Experts,
I have a customer who is currently implementing data guard 10.2.0.4 using a physical standby database. This customer wishes to use LGWR SYNC but using MAX PERFORMANCE as the transport log.
Is there any benefits to using this configuration? Issues?

Really no need to discuss what ever you configured if he not a technical guy, If he is really techie then he wont prefer too in maximum performance.

Problem with persistence in Generic Sync application

Hi:
We are developing an application which runson SAP Mi 2.5, SP 18,
Windows Mobile 5.0 and Generic Sync for PDAs.
We need persistence in our application. We tried with persistence API but
we found a problem and we send a message to SAP. Until we can solve
this issue we must implement persistence in other way to satisfy our customer requierements
Since now,we have implemented persistence with files but the performance of this solution does not meet our customer requirements (the search of data in the PDA is very slow).
We are thinking in another solution, which consists on using
Syncbos.Using this alternative, before making a generic sync, and
executing the code shown below:
SmartSyncRuntime.getInstance().getSyncBoDescriptorFacade
().getAllSyncBoDescriptors()
the returned syncBOS are those which I have defined in XML. On the
contrary, after making a generic sync, executing the same code, the
returned syncbos ARE NOT those whic I have defined in XML. The only
return that I get is the MIAUTH.
Any other ideas?
Thanks
Kind Regards

hi satur,
there are some things to take care if you want to use the persistence layer of the
SmartSync layer from your GenericSync app.
first, you have to let the MI client think that your application is using the
SmartSync functionality. this can be achieved by just including a dummy metadata
meRepMeta.xml file in the war archive during the deployment process. once the
MI client framework sees this during the installation, it will set a flag on the MSD
that your app is a smartsync.
second, if your app is considered a smartsync, MI will generate the delta request
and upload messages for your data if ever you have your SyncBo defined in the
metadata. Since you don't want such functionalities to be ON, i would suggest to
mark all your SyncBo as local ones; i.e. using attributes suppressDownload=true
and suppressUpload=true. this way, the MI framework will skip creating the requests
and delta upload messages for your app during the synchronization process.
third, your application has to have the syncEventListener implementation to get
notification when the Sync button (or event) was initiated. if you don't want your
app to be notified, you may just add synchronization button within your application
that will call your data manager to prepare your containers (i.e. retrieving the newly
inserted syncbo, modified syncbos and the list of deleted ones -> genericSync
containers) and to call the synchronizeWithBackend method.
fourth, you need to have the inboundProcessor that will parse your data and insert
them a SyncBo into your local database.
having tried this but i guess it might work...

Problem with Generic Sync after upgrade

Hi guru,
I have this problem:
I have done a upgrade ME2.1 -> MI2.5 SP18.
I have a simple Generic sync application that using a simple Function Module:

function Z_ME_TEST_CONNECTION.
""Interfaccia locale:
*" EXPORTING
*" VALUE(STATUS) LIKE BWAFSYHEAD-STATUS
*" TABLES
*" INBOUND_CONTAINER STRUCTURE BWAFCONT
*" OUTBOUND_CONTAINER STRUCTURE BWAFCONT
perform CALL_OFFLINE_ME_METHOD using 'TEST_CONNECTION'
 INBOUND_CONTAINER[]
 OUTBOUND_CONTAINER[].
OUTBOUND_CONTAINER-FIELDNAME = 'RESULT_CONNECTION' .
OUTBOUND_CONTAINER-LINENUMBER = 0 .
OUTBOUND_CONTAINER-FIELDVALUE = 'OK'.
append OUTBOUND_CONTAINER.
endfunction.
When i synchronize my mobile client it returns back
"EWAF 001Could not execute method Z_ME_TEST_CONNECTION"
Can anybody help me in resolving this?

Hi Sivakumar, I have write the my FM in the BWAFMAPP and the RFC destination in MEMAPPDEST but i have tha same error.

Authentication on MI Server + Generic SYnc

Hi,
When we call a RFC by Generic Sync, if i call this RFC 10 times, MI Client do the authentication (user+password) on MI Server 10 times? If yes, is there a way to increase the performance to do this authentication?
Other... If a user is add in 10 devices, if he needs update password, Will he need update in this 10 devices?
Or there is a way to do the authentication online on MI Server?

Hi Nameeta,
This synchronization time is with Windows Mobile 2003...
 10 seconds
MI Client -
> MI Server
 <----
 2 seconds
But, using the same WLAN, the tests with Windows Desktop are very differences...
 3 seconds
MI Client -
> MI Server
 <----
 2 seconds
I know that the hardware of Windows Mobile is less powefull than Windows Desktop, but how i said the WLAN is the same... i would like to understand the large difference...
Thanks for your attention.

Generic Sync Application and Persistence DB2e

Hi all,
I have a generic sync application. I need persistence and so, I have created a xml file with many syncbo to manage the persistence with db2e. If I execute the statement before the synchronization:
SmartSyncRuntime.getInstance().getSyncBoDescriptorFacade().getAllSyncBoDescriptors().size()
the result is five (because I have five syncbo).
But when I do a generic synchronization and I try to store data of this synchronization into syncbo, I get an exception because only there is one syncbo.
In fact, the previous statement returns only one synbo. This syncbo is called MIAUTH and I don´t have defined it.
How can I solve this issue? Thanks a lot.
Regards,

Hi all,
I know it is better to use persistence API than syncbos in generic sync application but we have many problems with persistence API and SP versions. While SAP solve our problems we are searching any alternative.
We use MVC and after doing generic synchronization, if the application generates a event and navigate to other jsp and in it, the application generates other event, I get all of my syncbos.
How could I simulate it, after generic sync finishes, in the same method by code? Any ideas?
Thanks and Regads.

Difference Smart Sync - Generic Sync

Hi all,
sorry for this simple and maybe stupid question, but I am a newbie in this topic. Can anybody tell me the differnce between generic sync and smart sync and when do i have to use them? Can they be used mixed or only one of them?
Thanks in advance for getting light in my darkness.
Michael

hello Michael,
On the client-side's view:
GenericSync is a lower layer that is responsible for data transport, connection and configuration updates.
SmartSync is another layer working on top of the GenericSync. In other words, SmartSync layer is just a GenericSync application that offers a wide-variety of features thru the SmartSync apis.
Yes you could mix GenericSync and SmartSync features in your application.

Generic sync not work correctly

Hi,
We are trying to get the inbound container in Java application, we use the method
GetElementsWithFieldName(String) in the object InboundContainer, this method returns an array that has only one entry, but really the wrapper function in R3 returns 6500 entries.
Best regards.
Thanks all.

hi Satur,
Is your Generic Sync Application Synchronous? you may find it in using the OutBoundContainer Type. if it is TYPE_OUTBOUND its asynchronous otherwise (TYPE_REQUEST) its synchronous. The same information can be found in MESYHEAD table entries too.
If it is Asynchrnous, then the MESYBODY Containers won't get deleted unless you sync from the client. if it is synchronous, it will disappear immediately.
I suggest your application be ASynchronous and check the same. If it still happens, there's some problem with your middleware. It is not taking the container as ASynchronous Processing. You'll have to go all over your Post-Installation Settings to check if all are right. (Tedious process indeed)
If it is synchrnous and your client is not receiving all the entries, the problem is with your receiver code handling. check your Process() method.
Regards
Ak.

Syncing Treo 680 with Mac PIMs (using Missing Sync)

Thanks to Michael Lafferty's excellent advice, I was ready to start syncing my Treo 680 with Mac's PIMs using Missing Sync. However, after extensive research and asking questions on five different forums, I'm getting conflicting advice. H
Here's my Treo PIMs situation:
Calendar 802K (6378 events/12 categories)
Contacts 1285K (2306/13)
Memos 184K (52/14)
Tasks 79K (250/10)
Here are the issues that I have received conflicting answers about:
1. I have 9 custom fields on my Treo with a lot of information in them. These are critical fields to me. It took me many days to pull this info out of my Contacts notes and enter in these 9 custom fields for 2306 contacts. Is it true that I cannot sync these 9 customs fields with Mac's Address Book? I've been told many times that this won't happen. If it can be done, will changes that I make in data entries for these fields in the Mac Address Book sync properly and be reflected on my Treo.
2. Can the conduits be set to "handheld overwrites Mac"? I've been told that it cannot. This and #1 are deal killers for me.
3. I have seven phone fields on my Treo. They are in this exact order:
work (1701 entries)
home (209)
Fax (291)
email (201)
mobile (201)
pager (31)
main (145)
Will I be able to successfully sync these with Mac's Address Book? If not, is there any reason that I couldn't take whatever fields won't sync and move them to some of the Treo 9 custom fields? The last question is moot if custom fields are not supported.
4. I average about 12 categories for each of my 4 PIMs. Do these all sync over correctly to the Mac PIMs?
5. I also have Treo notes attached to many, if not most, of my Contacts, Calendar events and Tasks. Will these all sync properly with the Mac PIMs such that I can make changes on either side of the equation and have them reflected after syncing on the other side?
6. Are there any other limitations in my ability to faithfully be able to recreate my 4 Treo 680 PIMs accurately and completely in the Mac PIMs?
I realize that any reference to non-Address Book PIMs is off-target. I hope you'll excuse me dumping the other three PIMs into the mix. My primary concern is Treo Contacts/Mac Address Book.
MacBook Pro Mac OS X (10.4.9) Treo 680 (DateBk6)

Q: I have 9 custom fields on my Treo with a lot of information in them…
A: The Missing Sync does not synchronize custom Address Book fields between a Palm device and your Address Book application, but will not remove those fields from the Palm if the conduits are set to synchronize. If your conduit is set to the nonstandard Overwrite handheld with desktop data, the custom fields will be overwritten. I point this out because it is, at times, necessary to make a choice like this, and as a result: its bye-bye custom field data!
The Missing Sync cannot perform custom field synchronization because the Sync Services framework does not allow The Missing Sync to create new fields in Address Book to match your Palm custom fields.
Q: Can… conduits be set to handheld overwrites [desktop]?
A: No, because again, the framework does not support this specific type of bidirectional data transfer.
Q: I have seven phone fields on my Treo…
A: This is an issue primarily with the manner in which a Palm device handles such information. Though they are displayed in a particular manner on your device, they are not necessarily stored in a specific order by the Palm contact application, and can only be retrieved when labeled with an expected or 'accepted' field label. This issue gets complicated quickly, but in short…
• only the first seven phone numbers sent to your device by the framework are written to the device
• the order is not something that can be controlled by a developer, and it is not necessarily the order displayed in either the Address Book contact record on your Palm device
• the Palm contact application does not distinguish between phone number and electronic mail address, though Mark/Space parses the data to look for the @ character—and, finding it—handles it as an electronic mail address
• only one of the several IM addresses you maintain in an Address Book contact record is transfered, and only one URL is transfered
• Palm categories are mapped to equivalent Address Book groups
As to synchronizing additional data to Palm custom fields, that's not supported. The place to put such data is in the Note: or Notes: field.
Q: I average about 12 categories…
A: As I suggested above, category and group equivalents are recognized and synchronized. Be sure that you name the ones you intend to synchronize identically in both environments.
Q: I also have Treo notes attached…
A: Again, these should synchronize bidirectionally, without issue.
Q: Are there any other limitations in my ability to faithfully be able to recreate…
A: Oh, yeah: because the data field labels and contents do not map 1:1, it is nearly impossible to create identical records in both environments. Look for the common abilities…
• a maximum of seven telephone numbers and electronic mail addresses
• a single IM identifier
• a single URL
…and work within those bounds. You can generally store and synchronize any additional identifiers in a Note: or Notes: record, but this is clearly less flexible and potentially more problematic than storing them in matching fields.
You briefly mentioned the other PIMs on your Palm device, and their OS X rough equivalents. Those controlled by Mark/Space OS X bundled applications will not be an issue: memos, for example. Their are Palm OS quirks which result in inequalities. The most obvious of these is the iCal multiple day event which spans two or more days in iCal, but which is represented on a Palm as only a single day event, displayed on the first day alone.

Problem during extraction using generic data sources

Hi
While performing extraction(master data) using generic data sources I am getting a problem.
while selecting application component, I am unable to find SD to select it.What should I do?
I selected CRM as application component and did the extraction , it is successful.
But what about if we want to select SD? I am guessing it as an installation problem ... Anyone plz help me
Thank you

Looks like the RFC connection between source system and BW system is broken..
Contact your basis team to check the connection what went wrong.
once the connection is re-established you can gohead ...

Generic Sync. support for non-SAP backend

Hi
Does Generic synchronization allows mobile applications to call function module residing in any non-SAP backend.I am not sure about this.
The documentation for MDK says we have to use Business Connector for this.
Where can i find the Business Connector for this purpose.
Which non-SAP backends are supported by Generic Sync framework.
