DB2 Version 10.1 for Linux, UNIX, and Windows

DB2 pureScale Feature enhancements

The IBM® DB2® pureScale® Feature was first introduced in Version 9.8. Version 10.1 builds on DB2 pureScale Feature support.

DB2 pureScale Feature included in DB2 server edition installations
In DB2 Version 10, you can install the IBM DB2 pureScale Feature while installing DB2 Enterprise Server Edition, DB2 Workgroup Server Edition, and DB2 Advanced Enterprise Server Edition.
DB2 pureScale Feature support added for AIX servers on RoCE networks
Support for IBM DB2 pureScale Feature on AIX® servers interconnected with a Remote Direct Memory Access (RDMA) over Converged Ethernet (RoCE) network has been added in DB2 for Linux, UNIX, and Windows Version 10.1.
Installation commands have been enhanced
Several installation-related commands have been enhanced to provide additional flexibility in installing and maintaining your DB2 environment.
Table partitioning is now available for DB2 pureScale environments
You can now use table partitioning for DB2 pureScale tables.
DB2 pureScale Feature can be validated using db2val command
You can now use the db2val command to verify the core functionality of a DB2 pureScale environment. The command validates the installation and instances.
db2cluster command now supports repairing an instance domain and controlling when an automatic failback occurs
The db2cluster command can now be used to repair an instance domain. Certain failure situations can be recovered more quickly by re-creating the cluster manager domain and any cluster resources. In addition, you can use db2cluster to control when an automatic failback of a member to its home host occurs.
New CURRENT MEMBER default value improves DB2 pureScale performance
The ALTER TABLE and CREATE TABLE SQL statements now have a CURRENT MEMBER option in the allowed set of default values.
New monitoring routine provides insight into group buffer pool usage
The new MON_GET_GROUP_BUFFERPOOL table function provides information that can help you determine whether the configured size for the group buffer pool (GBP) in a DB2 pureScale environment is properly sized.
DB2 workload manager is now available in the DB2 pureScale environment
With DB2 Version 10.1, you are now able to use DB2 workload manager (DB2 WLM) to manage your workloads when the IBM DB2 pureScale Feature is enabled. A good workload management configuration aids in maximizing system efficiency and throughput, while helping you to achieve your business performance objectives.
Diagnostic data collection for DB2 pureScale environments has been improved
Additional diagnostic data is now collected for DB2 pureScale components by the enhanced db2support command. This improved diagnostic data collection can help speed the troubleshooting process in DB2 pureScale environments.
FP2: Password-less remote root login for GPFS
For new DB2 pureScale installations, the new default for a DB2 managed GPFS™ file system no longer requires password-less remote root login as a prerequisite.
