Hello,
We are trying to integrate 64-bit 11.2.1_9 TimesTen. and we are getting the following error when performing UPDATE ....................... WHERE ROWID=? operation.
execute on 'SQLExecute(Select then Update: Update)

following is the content of .odbc.ini:

1. Can some one please point out what's going wrong?
2. Is there a way to calculate LogBufMB and LogFileSzie?
Thanks.

Answer 1

You store your transaction log files in LogDir=/tmp/logs
The error "TT0778: Log write failed because filesystem is full " indicates there is no more space on the disk on which /tmp/logs is created.
This is a Temporary datastore but it will still have transaction log files.
