The SMP/E process for installing z/OS elements or service z/OS system installation and maintenance |
|
This summary of SMP/E processing illustrates how z/OS® elements or service updates are installed. SMP/E provides an excellent inventory and cross-reference of software dependencies,
and a mechanism for installing new products or applying software maintenance.
These capabilities ensure integrity of the overall system. The mechanics of
using SMP/E to maintain a system can be quite simple, as shown in Figure 1.
How SMP/E works and the knowledge needed to package fixes and software producets
for SMP/E is significantly complex. IBM® provides instructions for system programmers
to follow with all SMP/E packaged fixes, software upgrades, and products.
Figure 2 provides a sample
of the job control language (JCL) that might be used to automate the process
from receiving updates to applying them to a target system.
Figure 2. SMP/E batch job example
//SMPJOB JOB 'accounting info',MSGLEVEL=(1,1) //SMPSTEP EXEC SMPPROC //SMPPTFIN DD ... /* points to file or data set containing SYSMODs to be received */ //SMPHOLD DD ... /* points to file or data set containing HOLDDATA to be received */ //SMPTLIB DD UNIT=3380,VOL=SER=TLIB01 //SMPCNTL DD * SET BDY(GLOBAL) /* Set to global zone */. RECEIVE SYSMOD /* Receive SYSMODs */ HOLDDATA /* Receive HOLDDATA */ SOURCEID(MYPTFS) /* Assign a source ID */ /* */. LIST MCS /* List the cover letters */ SOURCEID(MYPTFS) /* for the SYSMODs */ /* */. SET BDY(TARGET1) /* Set to target zone */. APPLY SOURCEID(MYPTFS) /* Apply the SYSMODs */ /* */. LIST LOG /* List the target zone log */. /* |
