DB2 10.5 for Linux, UNIX, and Windows

Converting your existing DB2 instances to a DB2 pureScale environment

Converting your existing DB2® instances to DB2 pureScale® requires that you update your instance to a DB2 pureScale instance.

Before you begin

Review the information in Planning to convert your environment to a DB2 pureScale environment.
Carry out the steps in Pre-conversion tasks for DB2 pureScale environments.
If your database is using the DB2 Partitioned Database Environment, you must convert your database to a single partition database before enabling to DB2 pureScale.

About this task

This task describes the steps for converting your existing instances to a DB2 pureScale environment. Some steps in this topic require that you are logged in as root.

Procedure

As root, convert the instance to a DB2 pureScale instance by issuing the db2iupdt command. For details on how to convert your DB2 V10.5 instance to a DB2 pureScale instance, see Updating an instance to a DB2 pureScale instance using the db2iupdt command.

Verify the instance conversion is successful by connecting to the databases and issuing a small query, as shown in the following example:

   db2 connect to sample

     Database Connection Information

    Database server        = DB2/AIX64 10.5.0
    SQL authorization ID   = TESTDB2
    Local database alias   = SAMPLE

   db2 select * from syscat.dbauth

Add additional members or cluster caching facilities by using the db2iupdt command or db2isetup command. A typical DB2 pureScale environment has two cluster caching facilities (CFs) and two members. For further details, see Adding new members or an additional CF.

What to do next

Update your instance to a DB2 pureScale instance with the db2iupdt command.
