Local fix
This fix is included in 8.0.1 fixpack 3
Problem summary
**************************************************************** USERS AFFECTED: Oracle EE Lookup and Upsert **************************************************************** PROBLEM DESCRIPTION: Slow performance with Oracle EE Lookup and Upsert stages when using character columns with indexes for SQL binds. **************************************************************** RECOMMENDATION: Apply this fix to correct performance issues for VARCHAR/CHAR indexed columns. Add new environment variable for jobs with national DB columns. ****************************************************************
Problem conclusion
Default charset bind changed to IMPLICIT because it is most likely charset bind form. New Environment variable added to support NCHAR bind form for national character columns. If binding a national character set columns then user should use the new environment variable APT_ORA_BIND_FOR_NCHARS. This environment variable must contain a comma delimited list of DataStage column names that are National character columns on the database side. The reason we need an environment variable is because it is impossible to detect/parse complex SQL statements and determine correct charset form for binds in every scenario.
