2、Create backup logical log files

[[email protected] informix]$ mkdir Logicallog_bak

[[email protected] informix]$ cd Logicallog_bak/

[[email protected] Logicallog_bak]$ touch 20220801

[[email protected] Logicallog_bak]$ ll

总用量 0

-rw-rw-r-- 1 informix informix 0 8月 2 00:54 20220801

[[email protected] Logicallog_bak]$ chmod 600 20220801

[[email protected] Logicallog_bak]$

3、Modify the backup file path

cd /opt/informix/etc

vim onconfig.tramsserver

LTAPEDEV /opt/informix/Logicallog_bak/20220801

或者LTAPEDEV /dev/null

4、Perform automatic backups

[[email protected] Logicallog_bak]$ ontape -a

Please mount tape 1 on /opt/informix/Logicallog_bak/20220801 and press Return to continue ...

五、报错4（err = -951）

报错内容

5:17:03 Get Shadow Password for user [informix] failed! 
15:17:03 Check for password aging/account lock-out. 
15:17:03 listener-thread: err = -951: oserr = 0: errstr = [email protected]: Incorrect password or user [email protected] is not kno. 

解决4

/etc/shadowPermissions are too dead,修改/etc/shadow其它用户可读,But this is not the final solution！ 
The ultimate reason is to implement it yourselfchown -R informix:informix /home/informix Changed some file permissions inside. 
解决办法：重装！！！
