"Invalid environment" generally occurs when a Multi-Tier Rulebook (default, oplrqb.ini) or Single-Tier $OPENLINKINI (default, openlink.ini) file is misconfigured.
For instance, a database agent configuration section may pass an invalid name to the Environment parameter.
Here is a sample database agent configuration section:
[generic_pgr7] Description = Default settings for PostgreSQL agent Program = pgr7_mv.exe Environment = POSTGRES7 ReUse = always
Here is a sample environment section:
[Environment POSTGRES] ;ODBC_CATALOGS = Y ; Uncomment after loading odbccat defs CURSOR_SENSITIVITY = LOW ; Set to HIGH after loading oplrvc.sql
"Invalid environment" will occur because the database agent section passes Environment = POSTGRES7, and there is no [Environment POSTGRES7].
To resolve the error, simply ensure that the Environment = POSTGRES7 and [Environment POSTGRES7] names match (i.e., either change [Environment POSTGRES] to [Environment POSTGRES7], or change Environment = POSTGRES7 to Environment = POSTGRES).
Similar errors may be found in Single-Tier configuration, generally within the $OPENLINKINI file, and occasionally involving cros-referencing settings found in $ODBCINI and/or $ODBCINSTINI.
