Restore database to another Db2 server with different endianness
My customer is using RHEL Big Endian Linux on PPC and Db2 10.5 which is end of support April 30, 2020. They have no option but to migrate to RHEL Little Endian. They cannot simply backup and restore the database and are looking at using Db2move wh...

We have automated backup options enabled (num_db_backups and rec_his_retentn both set). Our backup schedule takes a full backup on Sunday and a Delta every other day of the week. When a full backup image qualifies for removal, with reference to th...
This sqlcode SQL1246N is send by DB2 during an incremental backup each time a new tablespace has been created and no full backup of this tablespace has been done. It shoud be more interesting to switch automatically for this tablespace from the in...
