I am trying to use SQL Passthrough to send a create table statement to a remote database. The table will not be synchronized. The remote database is SQL Anywhere 22.214.171.12467 and is running on a Window 7 tablet computer. The consolidated schema is on a 126.96.36.199 Oracle database running on Solaris 10. The MobiLink server (SQL Anywhere MobiLink Server Version 188.8.131.5253) is also running on Solaris 10.
After a successful sync, the table is created in the remote database and the following row is added to the sync_passthrough_status table:
However, the next sync has an error when trying to upload this row to the consolidated Oracle schema:
I. 2013-04-05 15:21:23. <1> Received passthrough data from client: last run_time: 2013-04-05 14:35:23.875606

I thought that maybe it was truncating the blank spaces in the error_text field but this field in SQL Anywhere is long varchar (2GB maximum) and the field in Oracle is clob (4GB maximum).
Any other ideas?

I work on the SQLA side of a MobiLink-to-Oracle project and I know syncing these blobs does not work straight-forward with Oracle. (Apparently the other database company never read the iAnywhere development principle of "just make things work they way they should" :). I willl see if I can find the developer who solved the problem on the Oracle side for an actual answer, but I do know he found the solution after research on the web. I would suggest keywords MobiLink, Oracle and clobs.

I notice that your MobiLink clients are a newer build than the MobiLink server. It might not affect the problem, but the MobiLink server build should be greater than or equal to the MobiLink client build (at least for version 12 and earlier of SQL Anywhere).
Also, character set conversion can cause changes to string sizes, which might lead to the Oracle
