I created a new db2 database, updated LOGARCHMETH1, LOGFILSIZ and some other things, then tried to import data created with db2move and db2look with a command like this:
db2 -tvf filename.dat
It failed, with SQLSTATE=57019, because of BACKUP PENDING.
I didn’t feel like performing a backup on an empty database, so I did this to solve the problem:
db2dart databasename /CHST /WHAT DBBP off
where “databasename” was obviously the name of my database. This successfully changed the state of the DB Backup Pending flag to “off”, which allowed me to do my import! Yay!
