TroubleShooting

When running DMInstall.bin -i, it shows that the max number of open files is too little.

Extract install files..........
core file size          (blocks, -c) unlimited
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 26361
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024

POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 26361
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

The max number of open files is too little, suggest to set 65536 or more to number of open files.

Solution:

~]$ ulimit -Sn
1024
~]$ ulimit -Hn
65536

~]$ ulimit -SHn 65536
~]$ cat >>/etc/security/limits.d/99-dm8-limits.conf <<EOF
dmdba   soft   nofile    65536
dmdba   hard   nofile    65536
EOF

When running DMInstall.bin -i, it shows that the temp directory's size is too small

Installer Language:
[1]: 简体中文
[2]: English
Please select the installer's language [2]:
The Temp Directory's size is too small, please set the size more than 2G. Or set DM_INSTALL_TMPDIR environment variable to assign the temporary directory of DM Installer.

Solution:

a. Clean the /tmp trash files.

~]$ df -hT
tmpfs                 tmpfs     3.3G  2.1G  1.3G  63% /tmp

~]$ rm -rf /tmp/DMInstall

b. Set the DM_INSTALL_TMPDIR to a new location.

~]$ mkdir ~/tmp
~]$ cat >>~/.bash_profile <<EOF
export DM_INSTALL_TMPDIR=~/tmp
EOF
~]$ source ~/.bash_profile

libdmnsort.so: cannot open shared object file

~]$ /dm8/bin/dminit -i
/dm8/bin/dminit: error while loading shared libraries: libdmnsort.so: cannot open shared object file: No such file or directory

Solution:

~]$ cat >>/home/dmdba/.bash_profile <<"EOF"
export PATH=$PATH:$DM_HOME/bin:$DM_HOME/tool
EOF
