Database paths detected automatically by Db2 High Availability Instance Configuration Utility (db2haicu)

When you run Db2® high availability instance configuration utility (db2haicu) for the first time, db2haicu will search your database system for database configuration information that is related to cluster configuration.

Single database partition environment

In a single database partition environment, db2haicu automatically detects the paths:

  • Instance home directory path

  • Audit log path

  • Audit archive log path

  • Sync point manager (SPM) log path

  • Db2 diagnostic log (db2diag log file) path

  • Database related paths:

    • Database log path

    • Database table space container path

    • Database table space directory path

    • Local database directory

    Note: If any of the database related directories are symbolic links, the db2haicu utility prints an error message and exits.

Multiple database partition environment

In a multiple database partition environment, db2haicu automatically detects the following paths:

  • Database log path

  • Database table space container path

  • Database table space directory path

  • Local database directory

Automated HADR environment

In an automated HADR environment, db2haicu will prompt you to configure mount point monitoring for your HADR databases:
Do you want to configure mount point monitoring for the HADR database 'HADRDB'? [2]
1. Yes
2. No
If option 1, "Yes", is selected then db2haicu will automatically detect the following paths for your database and make them highly available by creating corresponding mount resources for them if eligible:
  • Database log path
  • Database table space container path
  • Database table space directory path
  • Local database directory
Note: A database path is eligible for high availability if the file system it resides on is of type JFS2, EXT3, EXT4, or XFS. Furthermore, in HADR environments, the data paths on the standby and primary database must be the same in order to be eligible.
