Changing the Structure Of the Database

When you modify the structure of a cluster-enabled database using the PROSTRCT utility, Clusters does the following:

PROSTRCT handles the updating of the cluster resource list of the cluster manager automatically. For more information about the PROSTRCT utility, see Progress Database Administration Guide and Reference .

After the change is complete, you must manually start the database with PROCLUSTER.

Adding Extents On a Volume Group or File System Different From the Database (AIX only)

Additional steps are required on AIX to add extents to a database on a volume group or file system that is different from the current location of the database. After modifying the extents with PROSTRCT, a file named PSC_CLUSTER_REG.TMP is created in the scripts directory located in your install directory. This file must be reviewed and executed.

Review the PSC_CLUSTER_REG.TMP file to make sure that it contains the correct path of all the added extents. This information is towards the end of the file with the title DatabaseDependency. If the paths are incorrect, follow the procedure below.

To correct and register the new extents with the cluster manager, perform these steps:

  1. Edit PSC_CLUSTER_REG.TMP and correct the paths for all the extents you added.
  2. Change your directory to $PSC_CLUSTER_PATH.
  3. Execute the following command which might take a few minutes to complete:
  4. bin/pscluster register scripts/PSC_CLUSTER_REG.TMP 
    

NOTE: Do not add extents to a volume group or file system already in use by another resource group.
