The capture and restore packages enable the user to capture all or part of
his system at a given condition and restore the system to a predetermined
condition in the event of a hardware or software failure. MDBF users of
the HPO feature may capture/restore individual subsystems. For
additional information, including a detailed explanation of the SIP macros
discussed below, see the TPF Database
Reference.
The SIP requirements for capture/restore include these SIP macros:
- The DDCCAP macro is used to establish the disk device control table for
capture/restore. Parameters may be submitted for up to four device
types. If coded, parameters for at least one device must be
entered.
- The LOGCAP macro is used to specify information relating to
logging/exception recording (LOG/XCP) processing. Values are entered to
specify the online module ranges to be assigned to each of the LOG/XCP
exception recording tapes.
- The RESCAP macro is used to specify error counts, channel utilization
percents, and other variable data pertaining to capture/restore. It is
also used to input the channel, control unit, and relative speed of available
tape units.
All these macros are required by SIP if the capture/restore facility is
desired.
