请教如何增加buffer cache的大小
我有一个大表,超过300个字段,1000W条,想要查询前1000条的时候,如果只选择20个字段:
select top 20 col1,col2.... from A,在interactive SQL中能显示出来,但是如果是提取所有的字段:
select top 20 * from A,则提示出错:
There was an error reading the results of the SQL statement.
The displayed results may be incorrect or incomplete.
main Bufman: All buffer cache pages are in use, ask your DBA to increase
the size of the buffer cache.
-- (s_blockmap.cxx 4062)
SQLCODE=-1009031, ODBC 3 State="HY000"
要我增加buffer cache的大小,请问应该如何解决这个问题? |
