Overview

The most significant change in this is release is support for a Unicode data type. From Wikipedia: "Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The latest version contains a repertoire of 136,755 characters covering 139 modern and historic scripts, as well as multiple symbol sets. The Unicode Standard is maintained in conjunction with ISO/IEC 10646, and both are code-for-code identical." The addition of Unicode will allow you to develop APPX applications to run in any language.

Line: 38 to 39
  There are additional considerations discussed in more detail at the end of the Upgrade instructions.

Record Length and Field Length Limits Increased

The maximum size of an Alpha/Text field is now 1M (1,048,576) characters. The maximum record length for an APPX/IO Type 9 (Large File) increased to 4,194,560 bytes. This is enough to store a maximum field size (1M Unicode characters) + maximum key size (255 bytes) + 1 alignment byte. APPX/IO Type 1 file record length limit remains at 32K. Oracle or MS SQL Server don't have record length limit.

  • If you use invalid collation, Appx uses the best alternative collation for you.
  • "APPX_QSORT_COL_NAME", "APPX_QSORT_COL_STRENGTH" environment variables override Appx collation for query processes. Note: setting these environment variables for queries is harmless and doesn’t need key file rebuild. So, it is a good idea to test different collations and strengths with Queries using these environment variables before changing the collation in APPX.
Changed:
<
<		You can set the COL_NAME to a locale name. Best collation then is chosen for the selected locale. For example, if you specify "en_BB" (English - Barbados), Appx looks for a collation with that name and If it couldn’t find one then the best alternative collation will be chosen, which in this case is "en". You can refer to https://www.localeplanet.com/icu/ for a list of locales.

  Valid Strengths for collations are:
  • -1: DEFAULT
Line: 100 to 101
 
  • 15: IDENTICAL
By default, APPX uses -1, however if you use an invalid value APPX uses 0 (PRIMARY).

64-bit APPX

Changed:
<
<		APPX 6.1 has been updated to run as a 64-bit application on some platforms.
>
>		APPX 6.2 has been updated to run as a 64-bit application on some platforms.
  You now have the choice of installing APPX as either a 32-bit or 64-bit application on both Linux and Windows. On other platforms APPX 6.1 remains a 32-bit application.
Line: 312 to 313
  The Output STANDARD ACTION LOG and the Input CONFIRMATION (END) have been added to application 0LC and can now be hooked.
