ora2pg 内存不足错误 - 在每个表之后

Question

当我尝试导出数据时，无论表大小如何(甚至是空表)，它都会耗尽内存。

Out of memory!            ]    162926/498508267 rows (0.0%) on total estimated data (14 sec., avg: 11637 recs/sec)
Issuing rollback() due to DESTROY without explicit disconnect() of DBD::Oracle::db handle (DESCRIPTION=(ADDRESS=(PORT=1521)(HOST=192.168.0.42)

Answer 1

问了作者，我得到了这样的答复:

You don't have enough memory. If you can't increase the memory size than reduce the value of DATA_LIMIT in ora2pg.conf. Try with 5000 and if it doesn't works use 2500.

已开通 ./config/ora2pg.conf和修改集 DATA_LIMIT 5000解决了这个问题。

我最初尝试添加更多 RAM，但仅将其从 2GB 增加到 4GB，但没有帮助。减少 DATA_LIMIT是解决方案。
