VERIFYUpgrade a Data Set’s End-of-File InformationIf an improperly closed data set (a data set closed as a result of system error) isopened, the VSAM OPEN routines set a “data set improperly closed” return codeto indicate the data set’s cataloged information might not be accurate. When thedata set is closed properly, VSAM CLOSE resets the “data set improperly closed”indicator but does not upgrade erroneous catalog information that resulted fromthe system error. Subsequently, when the data set is next opened, its end of data(EOD) and end of key range (EOKR) information might still be erroneous (untilVERIFY is entered to correct it), but VSAM OPEN sets the “data set openedcorrectly” return code.You can upgrade the EOD and EOKR information so that it is accurate when thedata set is next opened by closing the data set and issuing the VERIFY command://VERIFY JOB ...//FIXEOD EXEC PGM=IDCAMS//SYSPRINT DD SYSOUT=A//SYSIN DD *LISTCAT ENTRIES(TAROUT) -ALLVERIFY DATASET(TAROUT)LISTCAT ENTRIES(TAROUT) -ALL/*The first LISTCAT command lists the data set’s cataloged information, showing thedata set’s parameters as they were when the data set was last properly closed.The VERIFY command updates the data set’s cataloged information to show thedata set’s real EOD and EOKR values.The second LISTCAT command lists the data set’s cataloged information again.This time, the EOD and EOKR information shows the point where processingstopped because of system error. This information should help you determine howmuch data was added correctly before the system stopped.VERIFY will update only the high-used RBA fields for the data set, not any recordcounts.350 z/OS V1R6.0 DFSMS Access Method Services for Catalogs
Appendix A. Security Authorization LevelsThis appendix contains tables that show the required Resource Access ControlFacility (RACF) authorization levels for access method services commands. Thesetables include information for both non-SMS and SMS-managed data sets.If no RACF profile exists for a data set, you are authorized to access that data setwithout further RACF checking. The catalog RACF profile is not checked, even if itexists.The following tables are contained in this appendix:TableTable 5Table 6Table 7Table 8Table 9Table 10Table 11Table 12Required RACF Authorization TablesTable 5.
