The following compatibility observations apply to Business Continuity Manager with Vantage 2.2:
  • Business Continuity Manager 1.00.01 is only available on VMware and supports Teradata Vantage™ on the following platforms:
    • Vantage on-premises (IntelliFlex)
    • Vantage on VMware private cloud
  • Business Continuity Manager supports only one active and one standby system.
  • Due to recovery limitations, limit the use of volatile tables (VT) and global temp tables (GTT) in Business Continuity Manager-managed systems. Business Continuity Manager does not support non-deterministic write requests to VT/GTTs. Deterministic write requests to VT/GTTs are not recoverable if a failure happens after populating the VT/GTT and before completing all writes using the VT/GTT.
  • Business Continuity Manager supports write requests to tables that read from GTT, VT, or external tables as the data source and uses QueryGrid to replicate the target write table to the standby system.
  • Business Continuity Manager does not change routing rules based on alternative current users defined in Query Bands.
  • ​​Business Continuity Manager does not replicate the following: ​
    • Changes applied using sessions connected directly to Vantage outside of Business Continuity Manager
    • Object names, including usernames, when the name includes: periods, single quotes, and spaces
    • Sessions using Teradata Secure Zones
    • Sessions issuing QueryGrid, SQL-H, or Foreign Server requests
  • Business Continuity Manager does not support the following:
    • Expansion servers
    • Debugging of User Defined Functions (UDF)
    • Extended Multiload (MloadX)
    • Directly selecting from join indexes
    • Load isolation
    • Mainframe clients
    • Statement independence
    • TDNEGO authentication
    • Unicode pass-through characters
    • Fastload for the Teradata SQL Driver for Python
    • Load jobs with non-deterministic DML
    • JDBC FastExport
    • Partition-level locking
  • Business Continuity Manager supports up to 1 Million objects in managed dictionaries.
  • Business Continuity Manager does not synchronize DBQL objects as the objects are system-specific.
  • Business Continuity Manager does not support Viewpoint as Viewpoint is not required to monitor the Business Continuity Manager environment.
  • Business Continuity Manager requires the following:
    • All system-specific statements to be run using system-specific session routing rules
    • All managed Vantage systems and Business Continuity Manager servers to have the date-and-time and time zone synchronized using NTP or similar service
    • All managed Vantage systems to have CDM enabled to replicate statements using non-deterministic functions
    • Proxy-Authorization to be enabled in all managed Vantage systems
    • CDM to be enabled in order to issue CREATE/REPLACE PROCEDURE requests which are greater than 1MB in size
  • Business Continuity Manager uses CDM to replicate statements that use Identity columns and requires Identity columns to be defined such that the columns have different ranges on different systems.
  • Business Continuity Manager supports the following character sets: ARABIC1256_6A0, ASCII, EBCDIC, LATIN1250_1A0, LATIN1252_3A0, LATIN1254_7A0, LATIN1258_7A0, LATIN1258_8A0, LATIN9_0A, LATIN1_0A, THAI874_4A0, UTF8, and UTF16.
