Separate disks for transaction logs

You can store the DB2® table spaces and transaction logs on different disks to improve DB2 performance.

To improve DB2 performance, you can create containers for the LDAPSPACE and USERSPACE1 table spaces on a separate physical disk from the DB2 transaction logs. Separating table spaces and logs require three disks:

• Use two disks for the table spaces.
• Create containers for each table space on each disk.
• Use one disk for the transaction logs.

To move the table spaces, you must run backup and redirected restore commands. To move the transaction log, set the DB2 NEWLOGPATH and LOGFILSIZ parameters.
