ZSYSG ALTER-Alter System Generation Option Values

Use this command to change some of the system generation options that are defined using SIP. Only the file copy of the SYSTC bits is changed.

Requirements and Restrictions

You cannot use this command to alter the system generation options on a loader general file.

Format




NO
turns the system generation options off.

COMXT
allows you to call the message router user exit (COBC).

BPLOAD
bypasses loading the core resident program area (CRPA) during restart while the TPF system is cycling to 1052 state. Instead, the core resident programs are loaded when they are called for the first time.
Note:
Programs allocated using the SALO PRELOAD parameter are loaded to the CRPA regardless of the value specified for this parameter.

DBRBUF
allows you to write to buffered devices during database reorganization (DBR). See the TPF Database Reference for more information.

DLOCK
allows the TPF system to run record hold deadlock detection.

DTAC
includes detached data blocks in the online minidump.
Note:
The number of blocks included is defined by DETDATAX in the CZOCP DSECT.

KPFBK
specifies keypoint fallback. See the RAM macro in TPF System Generation for more information.

LTRCE
specifies DASD lock tracing. Use this parameter for debugging purposes only.

SELACT
enables or disables the E-type loader selective activate function. When enabled, selected ECBs can enter the programs in a selectively activated loadset. Otherwise, no ECBs can enter the programs in a selectively activated loadset.

TPFAR
allows support for the TPF Application Requester (TPFAR) feature.

UCS1
allows you to call the communication source common user exit (UCS1).

VEQR
specifies migration mode.

WUNS
causes the WTOPC message package to send unsolicited messages to remote terminals. Otherwise, the WTOPC message package sends remote terminals solicited messages.
