I'm getting a java.lang.OutOfMemoryError exception (2)

If DUDE still runs out of memory after setting the heapsize to 2Gb (maxium), then most probably you are dumping large LOB columns.  We define a large LOB as a LOB segment

larger then 1Gb.

If this is the case, you should switch on the parameter HUGE_LOB_SUPPORT.

Setting HUGE_LOB_SUPPORT=”true” in dude.cfg will turn on an on-disk-hashing algorithm for unloading lobs (as opposed to in-memory hashing).

The HUGE_LOB_SUPPORT was introduced after a case where DNA strands stored in LOBs had to be unloaded. The table contained - among others - 2 CLOBs columns, each being over 1Gb large.
