Makefile changes?

Yes, compile DataAccess ODBC driver on Linux

Omnidex Build 4.4.01A (June 2007)

Moderate

- Optimization of TOP, SKIP, EVERY and RANDOM clause of SELECT statements to take advantage of skips within indexing. - 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 a) ODBC and JDBC are based on an earliest compatible version, and b) 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

Minor

- 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. - Fix to oainfo to resolve problems with info calls in the ODBC driver - Improve performance of Hashed Data Cache on large result sets.

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. - Extend limit for Alt Sorts using Aggregation Indexes from 16 components to 32 components - Enhance Union View processing to honor DISTINCT_IN_PARTITION clauses on SELECT DISTINCT … statements. - Support for Postgres RDBMS using our DataAccess ODBC driver - Further support for partial-length components as partition qualifiers in Aggregation Indexes. - Change sequence of instructions in Omnidex kernel to circumvent a Microsoft compiler optimization error - Enhance grid (DBUNION) processing to honor UNIQUE_TO_PARTITION clauses on SELECT DISTINCT … statements. - Support for compiling and running in 32-bit mode on 64-bit Windows architecture. - Improve performance on Record Specific processing on Windows. - Support multiple databases in NODE section and multiple table.column in the UNIQUE_TO_NODE clause of DBUNION rule. - Fix error on criteria with long quoted strings - Favor ASK over MDK optimization for distinct key processing. - Fix problem with temporary files on certain aggregations.
