External Time Reference hardware facility (ETR) is the generic name for IBM Sysplex Timer. The ETR architecture provides the means of synchronizing TOD clocks in different CPCs with a centralized time reference, which in turn can be set accurately on the basis of UTC time standard (External Time Source). The […]
The cross-system coupling facility (XCF) component of z/OS manages communications between applications in a sysplex. XCF services allow authorized programs in a sysplex to communicate with programs on the same MVS system or other MVS systems. If a system fails, XCF services also provide the capability for batch jobs and […]
The following JCL creates a history data set from log data recorded on the Logrec log stream //LOGRECHS JOB,MSGLEVEL=(1,1),MSGCLASS=X,NOTIFY=&SYSUID //EREPDALY EXEC PGM=IFCEREP1,PARM=(‘HIST,ACC=Y,SYSUM’) //ACCIN DD DSN=SYS1.SYSPLEX.LOGREC, // SUBSYS=(LOGR,IFBSEXIT,,’DEVICESTATS,LASTRUN’), // DCB=(RECFM=VB,BLKSIZE=4000) //ACCDEV DD DSN=MVS.LOGREC.LGSTREAM.HISTORY, // DISP=(NEW,CATLG), // DCB=(RECFM=VB,BLKSIZE=4000), // UNIT=SYSDA,SPACE=(CYL,(25,5)) //SERLOG DD DUMMY //DIRECTWK DD UNIT=SYSDA,SPACE=(CYL,15,,CONTIG) //TOURIST DD SYSOUT=A,DCB=BLKSIZE=133 //EREPPT DD SYSOUT=A,DCB=BLKSIZE=133 […]
The following control statements are used to give EREP information about your configuration and set up the overall criteria for the way EREP creates the report: Control Description CONTROLLER Tells EREP to combine the error records associated with this particular control unit and its attached devices. DASDID Tells EREP that […]
The following parameters are used to control the way EREP processes the records that were selected: Parameter Description ACC=Y or N Accumulate. Tells EREP to copy the records used for the report into an output history file. Yes is the default value. HIST=Y or N History. Tells EREP that its […]
