Question

我有一个现有的monetdb安装和一个dbfarm。我想更改此（https://www.monetdb.org/Documentation/Guide/Multicores）docs页面中指定的monetdb使用的线程数。看起来我们需要使用mserver5而不是monetdbd启动monetdb才能设置此参数。所以，我尝试了以下命令：

mserver5 --dbpath=dbfarm/voc/ --set mapi_port=50000

 BBPdiskscan: unexpected file log.6, leaving /home/mskd/dbfarm/voc/bat/sql_logs/sql.
 BBPdiskscan: unexpected file BBP.dir, leaving /home/mskd/dbfarm/voc/bat/bat/BACKUP.
 # MonetDB 5 server v11.27.13 "Jul2017-SP4"
 # Serving database 'voc', using 8 threads

客户端无法连接到上述内容。

我认为这是因为上面的mserver输出的URI是错误的。通常，在使用monetdbd启动时，它会自动连接到URI：mapi:monetdb://127.0.0.1:50000/voc

有人可以指点我在使用mserver5启动monetdb时如何更改此URI？

Answer 1

I found how to do this. Have a look at the dbfarm/merovingian.log while starting it using monetdbd. The command is printed into the log file, change the threads parameter as needed.
