How You Prepare Your ApplicationsReserved Keyword ConflictsWhile the SQL parser recognizes most reserved keywords from context andusually resolves keyword conflicts without error, we recommend neverthelessthat you avoid the use of SQL reserved keywords.Check for and fix reserved word conflicts in databases and in application code(for example, in dynamic tables and views).For a complete list of reserved words, see the appendix “Keywords.”Re-image ABF ApplicationsThe introduction of column-level collation specification in Ingres 2006 causedthe data descriptor that is compiled into imaged Applications-By-Forms (ABF)applications to change.After upgrading, do the following:1. Delete the contents of the ABF object directory, $ING_ABFDIR/databasename/app-name.2. Re-image ABF applications.Report-Writer Syntax Change When Upgrading from Ingres 6.4When upgrading from 6.4, Report-Writer requires a space after all dotcommands.For example, “.NL3” must be changed to “.NL 3”.UNIX: To fix such occurrences automatically, you can use the following “sed”commands:sed -e 's/$[]\.[a-zA-Z][a-zA-Z]*$$[0-9]$/\1 \2/' foo.rw | \sed -e 's/^$\.[a-zA-Z][a-zA-Z]*$$[0-9]$/\1 \2/' >newfoo.rwCompare newfoo.rw against foo.rw to ensure that only the expected changesoccurred.An alternative to altering Report-Writer files is to sreport them into adatabase, then copyrep the reports back out.26 Migration Guide
How You Prepare Your ApplicationsReport-Writer Runtime Parameter Errors (UNIX)The following problem occurs only with Report-Writer applications developedunder Ingres 6.4.If string parameters that contain quotes are passed to Report-Writer, aruntime error may occur. This error may be caused by a change to the UNIXcommand parameter control file utexe.def.If such an error occurs, the utexe.def command parameter settings can bechanged back to that of Ingres 6.4.To change the command parameter back to the Ingres 6.4 utexe.defsettings1. Edit $II_SYSTEM/ingres/files/utexe.def.2. Search for the string "report report".3. Within that section find the string "(%S)".4. Change the string to: param '(%S)'.5. Save the file.6. Retest and see whether the error still occurs.This problem may occur even if you are upgrading from a more recent versionbecause typically the utexe.def file is replaced with every release of Ingres.Even if this issue was resolved during a prior upgrade, check to see if it hasnot reappeared in the latest upgrade.Creating a New Ingres Development Environment 27
