OA18319 OA18465 This is a problem with DFDSS dropping SMS RLS attributes from data sets under certain circumstances if the volumes that the data set is on is specified. Description: A VSAM KSDS with data and index components on different volumes may lose its RLSDATA during DSS COPY. The problem reported came about because input volumes were specified on a LOGINDYNAM parameter with COPY statemets similar to the following: COPY DATASET(INCLUDE(DATASET.KSDS)) - LOGINDYNAM( - (VOLUM1) - (VOLUM2) - ) - DELETE CATALOG - SPHERE When the data component resides on VOLUM2 and the index component on VOLUM1, the the RLS data is not propogated on COPY. If the order of the volumes in the LOGINDYNAM is swapped then the target data set will retain all of its RLS information. Local Fix: Do not specify input volumes. PTF List: Release 180 : UA29904 available 06/10/13 (F610) Parent APAR: Child APAR List: Page Error Description: Provide relief for DFSMShsm v1r8 recycle data loss APAR OA18372. 462 z/OS V1R8 DFSMS Technical Update Submitter Local Fix: Hold RECYCLE and mark any partial ML2 and backup tapes full using the DELVOL volser MIGRATION(MARKFULL) or DELVOL volser BACKUP(MARKFULL) command, as appropriate. A TOOL can be downloaded to determine if tapes have been impacted with the error reported in this APAR. See the README member contained in the tool for details. FTP server: testcase.boulder.ibm.com directory : /mvs/fromibm filename : OA18372.ANALYSIS.TOOL.TR
2) Log on to FTP server (user: ANONYMOUS, password: email) Then issue the following sequence of commands: cd mvs/fromibm bin get OA18372.ANALYSIS.TOOL.TR 'local.ds.name' (replace quit 3) Unterse the local file using job below: //STEP1 EXEC PGM=TRSMAIN,PARM=UNPACK //SYSPRINT DD SYSOUT=* //INFILE DD DISP=SHR, // DSNAME=%indsname //OUTFILE DD SPACE=(TRK,(10,10,20),RLSE), // VOL=(,,,1),DISP=(NEW,CATLG),UNIT=SYSDA, // DSNAME=%outdsname Responder Page Problem Summary: USERS AFFECTED: All V1R8 DFSMShsm users of RECYCLE. PROBLEM DESCRIPTION: Relief for OA18372. RECOMMENDATION: Relief for OA18372. Problem Conclusion: DFSMShsm RECYCLE processing will call error-processing module ARCERP to abnormally terminate under the conditions that would otherwise result in the loss of data described in APAR OA18372. Although the recycle function may terminate abnormally under certain error conditions, DFSMShsm V1R8 customers can resume normal recycle processing without fear of data loss. OA18372 will provide a complete resolution to the problem that will eliminate the deliberate abends added by OA18465. Should any of the following symptoms occur after OA18465 is installed, the customer is requested to notify IBM Software Support so that the error conditions leading to the abend can be analyzed. The following symptoms will be observed when the abend occurs: For recycle of a Migration Tape: ARC0200I TRAP IN MODULE ARCRCYPQ, CODE=0007, ABEND ONCE ADDED ARC0900I DFSMSHSM ERROR CODE 0007 IN MODULE ARCRCYPQ TYPE ABEND ARC0003I ARCRCYVS TASK ABENDED, CODE 800003EF IN MODULE ARCERP AT OFFSET 04B0, STORAGE LOCATION=xxxxxxxx ARC0834I RECYCLE TASK xxxx ENDING. RC=0023, REAS=000 The resulting dump will have the following title: ARCRCYVS TASK ABENDED CODE=800003EF IN MODULE ARCERP AT AT OFFSET=04B0, STORAGE LOCATION=xxxxxxxx For recycle of a Backup Tape: ARC0200I TRAP IN MODULE ARCRCYPQ, CODE=0005, ABEND ONCE ADDED ARC0900I DFSMSHSM ERROR CODE 0005 IN MODULE ARCRCYPQ TYPE ABEND ARC0003I ARCRCYVS TASK ABENDED, CODE 800003ED IN MODULE ARCERP AT OFFSET 04B0, STORAGE LOCATION=xxxxxxxx ARC0834I RECYCLE TASK xxxx ENDING. RC=0023, REAS=000 The resulting dump will have the following title: ARCRCYVS TASK ABENDED CODE=800003ED IN MODULE ARCERP AT AT OFFSET=04B0, STORAGE LOCATION=xxxxxxxx New return codes 5 and 7 will be added to Table 1 in the DFSMShsm Diagnosis manual (GC521083) for ARCRCYPQ.
