Info

Once FAST_VOLSEL is turned on, you see a new IGD17294I message when fast volume selection is used. An example of this appears in Figure 3-9, which is the output from an IEFBR14 job allocating a data set in a space-constrained storage group. IEF236I ALLOC. FOR IEFBR14 D301 IGD17294I FAST VOLUME SELECTION IS USED TO ALLOCATE DATA SET MHLRES3.MHLSMS.XLD301 IGD101I SMS ALLOCATED TO DDNAME (SEQOUTG ) DSN (MHLRES3.MHLSMS.XLD301 ) STORCLAS (MHLSMS) MGMTCLAS ( ) DATACLAS ( ) VOL SER NOS= SLD14D IEF142I IEFBR14 D301 - STEP WAS EXECUTED - COND CODE 0000 IGD104I MHLRES3.MHLSMS.XLD301 RETAINED, DDNAME=SEQOUTG IEF373I STEP/D301 /START 2007052.1126 IEF374I STEP/D301 /STOP 2007052.1126 CPU 0MIN 00.00SEC SRB 0MIN 00.00S Figure 3-9 Fast volume selection in action Migration and coexistence If you IPL a pre-V1R8 driver you need to remove FAST_VOLSEL from the IGDSMSxx member of PARMLIB if you included it while implementing z/OS V1R8. 3.3 COPY SCDS to ACDS This enhancement allows users to create an ACDS from any valid SCDS without first having to activate the ACDS. An example of its use is be to create an ACDS for use at a separate disaster recovery location. Preallocating the ACDS One of the requirements for this command is that the target ACDS for the COPYSCDS command must be pre-allocated. In Figure 3-10 we provide an example of an IDCAMS job to allocate a 60-track ACDS. Check the size of your existing SCDS to determine how many tracks your target ACDS should be. //ALLCACDS JOB CLASS=A,MSGCLASS=T,NOTIFY=&SYSUID,REGION=6M //STEP EXEC PGM=IDCAMS //SYSUDUMP DD SYSOUT=* //SYSPRINT DD SYSOUT=* //SYSIN DD * DEFINE CLUSTER(NAME(MHLRES3.TEST.ACDS) LINEAR VOL(SBOX11) - TRK(60 60) SHAREOPTIONS(2,3)) - DATA(NAME(MHLRES3.TEST.ACDS.DATA)REUSE) Figure 3-10 Pre-allocating your ACDS Using the new COPYSCDS command The requirements are: ► The ACDS must be pre-allocated. ► The source SCDS should be validated before being copied. 20 z/OS V1R8 DFSMS Technical Update
SMS automatically verifies that: ► The acds_dsn is not the currently active ACDS. ► The scds_dsn is a valid SCDS. If you do break any of these rules, SMS issues an IGD088I message, as in the case where we attempt to copy our SCDS into the active ACDS, as seen in Figure 3-11. SETSMS COPYSCDS(SYS1.SMS.SCDS,SYS1.SMS.ACDS) IGD088I COPYSCDS COMMAND FAILED SCDS SYS1.SMS.ACDS 313 - REASON CODE 6135 Figure 3-11 Example of the IGD088I message with COPYSCDS failure The command format for the new COPYSCDS command is: SETSMS COPYSCDS(scds_dsn,acds_dsn) Where scds_dsn is the name of the SCDS that is copied to the target ACDS acds_dsn. Figure 3-12 is an example of the SYSLOG output that you should expect to see after successfully issuing this command. SETSMS COPYSCDS(SYS1.SMS.SCDS,MHLRES3.TEST.ACDS) IEF196I IEF237I 831A ALLOCATED TO SYS00016 IEF196I IEF237I D30C ALLOCATED TO SYS00017 IGD019I SCDS SYS1.SMS.SCDS SUCCESSFULLY COPIED AS ACDS TO 243 MHLRES3.TEST.ACDS IEF196I IGD104I MHLRES3.TEST.ACDS RETAINED, IEF196I DDNAME=SYS00017 IEF196I IGD104I SYS1.SMS.SCDS RETAINED, IEF196I DDNAME=SYS00016 Figure 3-12 SYSLOG output from a successful COPYSCDS command Migration and coexistence There are no migration or coexistence considerations for the COPYSCDS support. 3.4 SMS serviceability A new DEBUG parameter has been added to the SETSMS TRACE command to add trace points at strategic locations and reduce the size of SMS trace data and therefore the amount of time needed to analyze the data. This serves to reduce the total time necessary for problem resolution. This parameter should only be used at the direction of the system programmer when engaged in problem determination. Chapter 3.
