You can change the formatting of decision table cells (for example, colors and fonts) in Excel and Rule Solutions for Office. However, the formatting is not synchronized into Decision Center, and the cells are displayed in their default format. If Rule Designer was previously used to format the decision table cells, the formatting of the cells returns to the format that was defined in Rule Designer.
Use only Rule Designer to edit a decision table cell format, and use this format throughout the lifecycle of the rule.
When using Decision Validation Services, Excel spreadsheets that contain dates prior to 1900 or 1904 produce test errors. Excel does not support dates prior to 1/1/1900 or 1/1/1904, depending on the Excel settings. See XL: The 1900 Date System vs. the 1904 Date System.

To use an older date, such as 6/15/1850, enter 15/06/1850 00:00:00:000 +0200 to use the internal date format of Decision Validation Services.

On Windows operating systems, when upgrading WODM 7.5 to, the upgrade fails, and you can find this message in the log files:

internal error occurred while updating packages. java.lang.OutOfMemoryError: Execution unit creation failure : retVal -1073741830, errno 12

In the Installation Manager INI file, IBMIM.ini, increase the memory space to 1,024 by doing one of the following:
  • Add the variable -Xmx1024m
  • Replace -Xmx512m with -Xmx1024m
The drop-down completion menu in the Intellirule editor might contain items from several domains in your BOM. To resolve the problem, see Unexpected values in domain drop-down.
When starting zRule Execution Server with z/OS APAR PM87944 applied, you receive the following error message:

BPXP029I OPEN ERROR FOR FILE PATH /usr/lpp/zDM/VxRxMx/zexecutionserver/msg/En_US.IBM-1047/

APAR PM87944 changes the behavior of the catopen() function to restrict the message catalog files that can be used by APF-authorized or z/OS UNIX set-user-ID and set-group-ID privileged programs. The message catalogs for these environments now require the program-controlled attribute to be set.

Mount the ODM HBRINSTPATH as a read-write file system and modify the attributes of the message catalog files. For example, use the command "extattr":
extattr +p /usr/lpp/zDM/VxRxMx/zexecutionserver/msg/En_US.IBM-1047/
Repeat this command for all message catalogs in the /usr/lpp/zDM/VxRxMx/zexecutionserver/msg directory.
