• Improve handling of TOP and SKIP operations in the grid processing with the Addin (DBUNION rule).
• Change version checking between client and server so that:
  • ODBC and JDBC are based on an earliest compatible version, and
  • CLOA is based on the Omnidex version, taking into consider whether info calls are to be used.
• For CLOA, the new property NoInfoCalls=Yes is supported, and if set, allows versions to sync on just x.xx, rather than x.xx.xx.
• – oaversion now supports showing the earliest
• Alpha internal release of OmniSearch

• Improve debug messages to show better operating system information in banners and trace files.
• Fix abort that occurs when column alias is a literal, but order by is a column.

• Port to 64-bit Linux

• Change oahelper’s generation of Omnidex installation scripts from a Unix shell script to a two input files, one for installing indexes and one for building indexes

• Fix error in Omnidex kernel in large wildcard qualifications, such as 1995@ (Axciom)

• Allow partitioning of all tables for grid environments, rather than restricting to child tables
• Improve table join support for grid environments

• Support for partition qualifiers in aggregation indexes that have partial columns as the first component
• Support for partition qualifiers in aggregation indexes that have partial columns as the first component
• Support for the DISTINCT_IN_PARTITION option to the COLUMN statement within Union Views. This option indicates that count distinct operations on this column are better optimized because the administrator guarantees that values are distinct within each partition.
• Support for the CACHE/NOCACHE options in the DBUNION rules in environment files. This option indicates that the grid processing should cache connections to the node so that repeated calls to CLoaconnect, CLoaopencursor, CLoaclosecursor and CLoadisconnect are not needed for each node within each query.
