CICS® VR
Version 4 Release 3 contains these changes.
- Enhanced server address space configuration
- Customize names for started tasks: CICS VR operations involve the use of a
number of MVS™ started
tasks. When CICS VR
constructs a job name, it can now optionally include a system identifier instead
of system slot number, to guarantee that the name of the job is unique across
the sysplex, enabling unique security profiles to be associated with the jobs.
- VSAM REDO batch logging continue control: You can specify the maximum
job step return code that CICS VR treats as the successful completion of the job
step to continue VSAM REDO batch logging.
- Server set up control: You can specify a setup job that must be
run during the initialization of the CICS VR server address space.
- Scavenger run control: You can set both the time interval parameter
and the start time parameter to control the scavenger runs.
- Selective backup registration control: You can automatically register
in the RCDS only backups for which VSAM spheres were already registered.
- None string handling: As a usability aid, you can specify a value
of NONE in place of a blank or null string for CICS VR parameters in the IGDSMSxx parmlib
member. See Defining a CICS VR general control parameter.
- Setting CICS VR
Server address space defaults from the ISPF dialog Authorized users can
specify CICS VR
server address space defaults from the CICS VR ISPF dialog interface, as well
as from the CICSVR_GENERAL_CONTROL parameter. See Setting CICS VR server address space defaults.
- Server address space security improvements
- CICS VR
can protect the RCDS from being updated by any user when the panel interface
is used. You can specify that the user's security profile must be checked
before allowing certain information in the RCDS to be added, changed, or deleted.
CICS VR
can protect the RCDS from being updated by any external service request to
the CICS VR
server address space from batch jobs. The RCDS protection from non-authorized
usage has improved. See CICS VR security.
- Automation enhancements
- Automation is enhanced and integration improved.
- You can enable and disable the CICS GLUE DWWXFCBF dynamically by means
of CICS transactions
or EXEC CICS LINK
commands to appropriate programs, in addition to the current enabling method
by PLTPI.
- You can find out the state of the CICS VR Server, and, if it is not active,
try to activate it in the GLUE enabling process.
See Preparing for Automated Recovery.
- Duplicate recovery runs prevention
- You can prevent the running of duplicate recovery jobs by using the new
Recovery Submission Manager tool. See Preventing duplicate recovery runs.
- Time range for batch backout
- You can specify a stop point for Batch Backout. Support has been added
for stoptime and stoptod keywords.
You can specify a stop point for Batch Backout. The time range for Batch Backout
is started by adding STOPTIME or STOPTOD keywords to the command input in
the DWWIN DD statement. See BATCHBACK: Remove updates to VSAM spheres.
- Improved backup deregistration
- You can specify multiple criteria for automatic backup deregistration
on the CICS VR
automatic backup deregister window by specifying values for the following
input fields:
- Backup retention period: An integer between 0 and 999 specifies
the number of days CICS VR keeps information about backups in the RCDS.
- Use log retention period: A value of 1, Yes, specifies that CICS VR
deregisters backups when coinciding log data that is also deregistered by
the CICS VR
automatic log stream deregistration function.
- Use catalog information: A value of 1, Yes, specifies that CICS VR
deregisters all registered non-DFSMShsm backups that are not in the ICF catalog.
- See Setting automatic backup deregistration criteria.
- ISPF Global Time Presentation Setting
- You can choose a format for timestamp representation on panels by using
the new option, ISPF Global Time Representation Setting. See Setting the global time format.
- Last Data Set Filter
- You can enter the sphere list with the last used data set name filter
without having to specify values for input fields every time that the CICS VR
VSAM sphere include window is displayed. See Specifying criteria for the VSAM sphere list.
- RCDS extract utility
- A new keyword, SPHERES, has been added to the RCDS EXPORT command, when
you specify SPHERES CICS VR copies information about the specified data
sets to an EXPORT file which can be used with IMPORT to load a new RCDS. The
values in the keyword specify the names of the data sets for which the information
is copied. You can select information only about the specified data sets that
you require to be copied from one RCDS to another. See RCDS: Create a RCDS copy.
- Journal print filtering
- You can now print only a part of the contents of the mvslogs and information
about certain records logged on them. Include and Exclude filtering, using
the same criteria as for logical recovery, has been added. CICS VR now provides
print filtering for records logged on an mvslog. See PRINT: print information about records logged on an MVS log.
- Logcopy filtering
- You can copy only a part of the contents of the mvslogs. In addition to
normal copying you can use Include and Exclude filtering using the same criteria
as for logical recovery. The Logcopy function filtering is started by adding
EXCLUDE or INCLUDE commands, or both, to the command input in the DWWIN DD
statement. See LOGSTREAMCOPY: Copy an MVS log stream.
- Miscellaneous release changes
- The IVP procedure now includes CICS VR server address space setup, server
start, and batch logging.
- Recovery now supports use of HSM Version 0 backups available with z/OS® 1.10.
