RDF System Management Manual for J-series and H-series RVUs (RDF Update 13)

• Chapter 3 (page 58) explains how to install and configure RDF, including how to copy

databases and files from the primary system to the backup system before starting RDF.

• Chapter 4 (page 88) discusses how to operate RDF, including how to issue RDFCOM and

RDFSCAN commands and how to display RDF configuration parameters and operating

statistics, change configuration parameters, and interpret log files.

• Chapter 5 (page 110) explains how to manage the RDF environment, including how to recover

from file-system errors, respond to failures, stop and restart the RDF product, direct the backup

system to take over application processing when a disaster occurs at the primary system site,

and perform other specialized tasks.

• Chapter 6 (page 147)details how to back up altered database structures and how to

resynchronize the primary and backup databases.

• Chapter 7 (page 157)describes how to synchronize entire databases or selected database

volumes online.

• Chapter 8 (page 175) and Chapter 9 (page 254) present the syntax of all RDFCOM and

RDFSCAN commands, respectively, and give examples of these commands.

• Chapter 10 (page 264) describes the triple contingency feature.

• Chapter 11 (page 271) describes subvolume-level and file-level replication.

• Chapter 12 (page 277) describes how to use the map-file, map-log, and updater configuration

record to support mapping between primary system and backup system subvolumes.

• Chapter 13 (page 282) describes support for auxiliary audit trails.

• Chapter 14 (page 286) describes support for network transactions.

• Chapter 15 (page 299) describes lockstep operation.

• Chapter 16 (page 316) describes SQL/MX database setup for RDF.

• Chapter 17 (page 329) describes the Zero Lost Transactions (ZLT) functional capability.

• Appendix A (page 339) summarizes the syntax of all RDFCOM and RDFSCAN commands.

• Appendix B (page 350) provides additional information about RDF, including reserved words,

default values for configuration parameters, and system file descriptions.

• Appendix C (page 356) lists all messages that can be generated by the lockstep gateway, RDF

processes, RDFCOM, and RDFSCAN, and their probable causes, effects, and recovery actions.

• Appendix D (page 491) lists all the operational limits that apply to the RDF/IMP, IMPX, and

ZLT products.

• Appendix E (page 492) describes how to monitor RDF entities using ASAP.
