Oracle Trace文件中mxlc的含义

前端之家收集整理的这篇文章主要介绍了Oracle Trace文件中mxlc的含义前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我在跟踪文件中看到以下内容

Bind#3 oacdty=01 mxl=128(35) mxlc=36 mal=00 scl=00 pre=00
oacflg=03 fl2=1000010 frm=01 csi=31 siz=0 off=168
kxsbbbfp=ffffffff79f139a8 bln=128 avl=35 flg=01 value=”1234 W
1234 West,West Groves City”

我想知道mxlc值是什么?
