This article will combine the author's recent work, in the Oracle database paging query, encountered a small problem, for you to explain how to solve the Oracle paging query sorting and efficiency issues.
The original paging query SQL code is as follows:
Select RowNum RN, t.id ID, o.name yyb,u.name XM, T.MC from Tzdysx
T,tuser u,lborganization o where t.cjr=u.id and u.orgid=o.orgcode and T.GX = 1
ORDER BY ID
The results are as follows:
RN ID yyb XM MC

local images. I first tried Picasso and is happy, but the later I decided to switch to the UIL for more customization options.Picasso:
Picasso ' s fluent interface is nice. But jumping around with "to", "to", "load" you actually don ' t know what's behind the scene. It ' s confusing what's returned.
Picasso allows you to specify exact target size. It's useful when you had memory pressure or performance issues, you can trade off some image quality for speed.

How does one make ethtool settings permanently stored on network devices?
Solution 1: The ethtool settings can be saved in the/etc/sysconfig/network-scripts/ifcfg-ethx file to activate the options when the device starts next time.
For example, ethtool-s eth0 speed 100 duplex full autoneg off this command sets the eth0 device to full-duplex adaptive, and the spe
