Actions and Requirements at r11 when CXX Is Version 12

If fallback is needed, convert the Version 12 CXX back to r11 format and style. With the CXX at r11, all r11 features are permitted. The ability to open a version 12 CXX requires solutions applied to r11. Without solutions applied, the r11 code does not recognize the CXX and generates a return code 47(024).

With r11 solutions, the following applies:

• The DB00905 message indicating the Directory (CXX) version reflects 12 when it occurs.
• The DBUTLTY function BACKUP with AREA=CXX fails with message: DB13149 - WRONG CXX RELEASE FOR THIS FUNCTION. With the solution, r11 does not have the ability to understand all the Version 12 changes or be able to successfully back them up.
• The DBUTLTY function LOAD with AREA=CXX fails with message: DB13149 - WRONG CXX RELEASE FOR THIS FUNCTION.
• The existing message: DB13060E - CXX BACKUP IS VERSION 12, CANNOT LOAD TO CXX VERSION 11, in Version 12 fails. Users who require the ability to move a CXX database definition from a version 12 CXX to an r11 CXX should add a temporary r11 CXX and downgrade the backup using the Version 12 command, CXXMAINT OPTION=CONVERT1211, then use r11 to BACKUP the temporary r11 CXX.
• The MUF properly supports the CXX level Version 12 options of AREAEV and DATAHU known in r11 as DIAGOPTION_CXX 08 and 32. The MUF does not allow any use of 'DIAGOPTION CXX'.
• The r11 DBUTLTY function REPORT with AREA=CXX is not enhanced to print any additional Version 12 information. It prints all databases that are FORMAT 1. If a database is FORMAT 2, it skips the database after printing the message: DB13102 - WRONG DATABASE FORMAT FOR THIS FUNCTION.
• The DBUTLTY function CXXMAINT with OPTION=CONVERT fails with the message: DB13149 - WRONG CXX RELEASE FOR THIS FUNCTION.
• The Version 12 CXX must have a CXX level of LEVEL 1.
• The open of a database for any purpose that is defined as FORMAT 2 fails with a return code 94(094).

Note: This is intended for special case test systems only and not for user production. Users in production are expected to convert the CXX from Version 12 to r11, if a fallback is needed.
