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 […]
As always there’s more than one way to skin a cat and listing the z/OS UNIX System Services file systems currently in use is no different. You can use ISHELL, OMVS, you can write a script,… or you can simply use an MVS command to do it. What MVS command […]
The following REXX code will list all tasks that are currently running on the mainframe system: /* REXX */ /* Developed by S. Tresadern */ cvt = c2x(Storage(10,4)) asvt = mvsaddr(cvt 22C 4) asvtmaxu = x2d(mvsaddr(asvt 204 4)) do i = 0 to asvtmaxu – 1 offset = d2x(x2d(210) + […]
If you work with mainframes, you are probably familiar with UACC (universal access) and ID(*). Many people believe that UACC and ID(*) represent the same thing. This is not true. They are slightly different and you need to take the difference in consideration when planning your RACF security environment. Access Authority Description […]
The following CARLa script will list the RACF Global Access Table (GAT) profiles: n i=base s c=general and s=base c=GLOBAL sortlist class(key,pas) searchkey(key,nondispl) key(key,pas,12), memlst(header,0,sort) The result of the above CARLa script should look like: Class Profile key Members GLOBAL DATASET &RACUID.**/ALTER SYS1.HELP/READ
