Hi All,

I am building a SOA BPEL application in Oracle 12c, which gets the list of files in a folder with minimum file age > 60 secs and start processing them.

I am facing issue at the first step, when File Adapter tries to get the list of files in a folder containing 90,000 files. Also, I have got transaction time out exception. I was told not to increase the Time Out settings as it affects all the BPEL processes transactions. Hence, It is returning blank value.

How can I overcome this issue without altering the transaction time out setting change?


Any help is much appreciated.

Thanks in advance!!

    Hi Hari,

    To determine exactly what is going on, enable TRACE:32 for oracle.soa.adapter.file , reproduce the issue and check SOA managed server diagnostic logs.

    Refer:    How to enable TRACE / DEBUG logging in Oracle SOA Suite 12c And Oracle Service BUS 12c (Doc ID 1903013.1)

    In case timeout is occurring before the result of listfiles is returned , more time has to be allowed and hence timeout values have to be changed.

    While changing timeout , follow the rule mentioned in

    SOA 11g and SOA 12c: How to configure transaction timeouts for BPEL (Doc ID 880313.1)
