IBM utility IEBGENER can be used to copy the content of one dataset into another via batch. The basic JCL for this effect is as follows: //COPYFILE EXEC PGM=IEBGENER //SYSPRINT DD SYSOUT=* //SYSUT1 DD DSN=input_dataset,DISP=SHR //SYSUT2 DD DSN=output_dataset,DISP=(,CATLG), // VOL=SER=volser, // SPACE=(CYL,(xx,yy),RLSE) //SYSIN DD DUMMY //SYSUDUMP DD SYSOUT=* //* You […]
The following are the in-built security features that come with z/OS: System Authorization Facility (SAF): SAF is part of the operating system. SAF is available whether or not an additional security product such as RACF, ACF2 or Top Secret is installed. If an additional security product is installed, SAF routes […]
The RACF database contains records whose format is controlled by a set of database templates. The templates map out how profiles are written on the RACF database. IBM makes changes to the templates to add new segments to the RACF database, or to add new fields to existing segments. The […]
The following JCL is an example on how to use IBM DFSORT ICETOOL utility to produce a report on SMF records (record type 80 in our example): //SMFRPTR EXEC PGM=ICETOOL //RAWSMF DD DISP=SHR,DSN=SYS2.WEEKLY.SMF(0) // DD DISP=SHR,DSN=SYS2.WEEKLY.SMF(-1) // DD DISP=SHR,DSN=SYS2.WEEKLY.SMF(-2) // DD DISP=SHR,DSN=SYS2.WEEKLY.SMF(-3) //TEMPSMF DD DSN=&&TEMPS,SPACE=(CYL,(15,15)),UNIT=SYSDA //REPORT DD DSN=USER1.SMF.REPORT,DISP=OLD //TOOLMSG DD […]
Here’s a simple example of a batch job to clear the content of your SMF datasets: //SMFDP EXEC PGM=IFASMFDP //INDD1 DD DISP=SHR,DSN=SYS1.MAN1 //INDD2 DD DISP=SHR,DSN=SYS1.MAN2 //INDD3 DD DISP=SHR,DSN=SYS1.MAN3 //SYSPRINT DD SYSOUT=* //SYSIN DD * INDD(INDD1,OPTIONS(CLEAR)) INDD(INDD2,OPTIONS(CLEAR)) INDD(INDD3,OPTIONS(CLEAR)) Explanation: INDDx – are the DD cards that specify the SMF datasets. SYS1.MANx […]
