| Problem description: | |
Due to code changes on 9.7 FP1 to address excessive I/O on standby when large buffer pool is used, standby is not flushing buffer pool pages on SOFTMAX. Some of the other symptoms customers will see are as follows: 1. Standby would retain logs longer than necessary since headextent ID/ minbufflsn is not moving up 2. Since minbufflsn is not moving faster, this may eventually cause log dir to fill up and shutdown standby. | |
