1 问题现象

配置达梦DMHS 初始状态的时候，报如下错误：

DMHS >copy 0 "sch.name='SYSDBA'" DICT|LSN|CREATE|INSERT|INDEX 

CSL[ERROR]: 加载日志分析模块失败

查看日志，错误如下：

2022-12-22 07:54:29 PUB[INFO]: set enable_directio = 0

2 解决方法

提示缺失的文件实际是存在的，所以怀疑是环境变量配置的问题：

[dave@www.cndba.cn log]$ find /dm -name libdmoci.so
/dm/dmhs/bin/stat/libdmoci.so
/dm/dmhs/hs_agent/libdmoci.so
/dm/dmhs/db/bin/libdmoci.so
/dm/dmhs/INST_STAT/USTC/libdmoci.so


[dave@www.cndba.cn USTC]$ pwd
/dm/dmhs/INST_HS/USTC
[dave@www.cndba.cn USTC]$ cat ~/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

export DM_HOME="/dm/dmdbms"
export LD_LIBRARY_PATH="/dm/dmdbms/bin:$LD_LIBRARY_PATH"
export PATH="/dm/dmdbms/bin:$PATH"

export DM_HOME="/dm/dmdbms"
export DMHS_HOME=/dm/dmhs
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/dm/dmhs/bin:/dm/dmhs/db/bin:/dm/dmdbms/bin:/dm/dmhs/db/bin

export PATH="/dm/dmdbms/bin:/dm/dmhs/bin:/dm/dmhs/db/bin:$PATH"
[dave@www.cndba.cn USTC]$

但修改配置，然后重启，并没有解决问题。 http://www.cndba.cn/cndba/dave/article/116421http://www.cndba.cn/cndba/dave/article/116421

所以ldd 了一把，看到调用的是/dm/dmhs/bin/libdmoci.so：

[dave@www.cndba.cn USTC]$ ll libcpt_dm8.so
-rwxr-xr-x 1 dmdba dinstall 942561 12月 22 05:10 libcpt_dm8.so
[dave@www.cndba.cn USTC]$ ldd libcpt_dm8.so
        linux-vdso.so.1 =>  (0x00007ffc5a1d4000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f85f4ac7000)
        libm.so.6 => /lib64/libm.so.6 (0x00007f85f47c5000)

        libdmhs_net.so => ./libdmhs_net.so (0x00007f85f3c4a000)
        libdmhs_ld_dm8.so => ./libdmhs_ld_dm8.so (0x00007f85f39eb000)
        libdmhs_ucvt.so => ./libdmhs_ucvt.so (0x00007f85f3493000)
        libdmoci.so => /dm/dmhs/bin/libdmoci.so (0x00007f85f288e000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f85f5169000)
        libdmhs_bool_parse.so => ./libdmhs_bool_parse.so (0x00007f85f2681000)
        libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007f85f237a000)
        libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f85f2164000)

所以接单粗暴的把这个文件复制到DMHS 实例目录下，再次初始化，就没有报错了：

[dave@www.cndba.cn USTC]$ pwd
/dm/dmhs/INST_HS/USTC
[dave@www.cndba.cn USTC]$

[dave@www.cndba.cn USTC]$ cp /dm/dmhs/hs_agent/libdmoci.so .
