bash shell version of db2uext2 (DB2 USEREXIT),backup archive log to remote host!

5 New Member

How to automate backup archive log to remote host?


Using the IBM supplied UserExit sample program db2uext2.cdisk? It's too complex and allways is error while compiling.


So I decide to write a bash version of db2uext2, ant it works!


1. create bash shell file
Expand|Select|Wrap|Line Numbers
  1. nano -w /home/db2inst1/sqllib/bin/db2uext2
  2.  
2. modify permissions
Expand|Select|Wrap|Line Numbers
  1. chown bin:bin /home/db2inst1/sqllib/bin/db2uext2
  2. chmod 755 /home/db2inst1/sqllib/bin/db2uext2
  3.  
3. update LOGARCHMETH1 to USEREXIT
Expand|Select|Wrap|Line Numbers
  1. db2 get db cfg for DBNAME | grep LOGARCH
  2. db2 update db cfg for DBNAME using LOGARCHMETH1 USEREXIT
  3.  
4. wait or restart db2 immediately
