MAU/MAM Sync Problem

[Former Member]

Hello all.

I have deployed MAU to my PC and to a PDA. I use the same

user and the same middlerware and backend to sync data.

When I sync with my PC everything is fine.

When I sync on PDA I get the followong error:

E [MI/Smartsync ] java.lang.RuntimeException: No relation source FieldDescriptor found for ID: UMAM_031_090_MEASUREMENT_POINT

java.lang.RuntimeException: No relation source FieldDescriptor found for ID: UMAM_031_090_MEASUREMENT_POINT

I installed the MI on a CF Card on PDA, but I guess this should not be the problem ??!!

Thanks for any help.

Hi Sascha,

check note 911043 - Generation of meRepMeta.xml for MAU . THey changes MW fields but didn't adjust xml file...

Hi Thomas.

Thank you for the hint. But why is it working on my PC then? It is the same WAR file. And I use the same user to sync. I just reinstalled everything on PDA and I get the same result.

I dont have any ideas.

Best regards,

Hi again.

I removed MI from the storage card and reinstalled in the normal PDA storage. Now the sync works more or less. I do not receive the error anymore and I receive data. But it seems the sync is running endless.

Does anyone have any idea what things have to be done to make things running on a storage card installation? I followed the guide and it works including the download of the MAU client. But the sync is not working.

Best regards,

Sascha

Hi,

which DB type are you using. Seems CF Card requires DB2E:

Note 813620

VII Changes to Documentation

<i>The following prerequisites are missing in the documentation:</i>

...

<i>Installation on Compact Flash Card: You are using an MI client and and mobile applications having DB2e as persistence.</i>

Hi Thomas.

We do not use a DB so this must be the problem.

Thanks a lot.

Best ragrds,

hello sascha,

looking at the log, seems that there's a problem with your

application's xml metadata. try checking by looking into

the meRepMeta.xml whether the relation is properly defined

for syncbo: UMAM_031 row: 090 field: MEASUREMENT_POINT.

regards
