CICS® VR
Version 4 Release 1 contains the following changes.
- CICS VR
Security
- Security has been enhanced to protect the RCDS from being updated by any
user. It is possible to specify that the users security profile must be checked
before allowing certain information in the RCDS to be added, changed, or deleted.
- RCDS REPORTS
- Recovery reports can be created to identify the information required to
enable recovery of a remote site. In particular, detailed information can
be obtained to determine what is needed to recover a main or remote site from
a disaster or to keep the site up-to-date. Other reports provide information
that show when VSAM spheres were used and where the records were logged, information
about each registered backup in RCDS, and information about registered mvslog
copies in RCDS.
- Automated Recovery
- The CICS VR
Automated Recovery function has been added. This provides an automatic or
semi-automatic repair or reorganization of a VSAM data set after a backout
failure has occurred in CICS TS, when attempting to back out changes to the
data set.
- Backup initiation
- Backup can now be initiated using an ISPF dialog.
- Automatic deregistration for change accumulation data sets
- Automatic deregistration for change accumulation data sets has been added.
- CICS/ESA V4R1
is no longer an IBM-supported release of CICS
- None of the new functions added to CICS VR V4R1 have been designed for use
or tested with CICS/ESA V4R1.
Documentation specific to CICS/ESA V4R1 support has been removed from this
manual to reflect the changes made in CICS VR V4R1.
- Perform tasks
on CICS Backout
Failed spheres
- CICS spheres
are registered for manual recovery or reorganization after CICS notification
of a backout failure. A dialog has been provided to perform these tasks using
a CICS Backout
Failed sphere list panel.
- Running backup from CICS VR Panels
- Backups can be initiated using the CICS VR ISPF dialog interface.
- RCDS Reports
- Recovery reports can be created to identify the information required to
enable recovery of a remote site. In particular, detailed information can
be obtained to determine what is needed to recover a main or remote site from
a disaster or to keep the site up-to-date.
- Local/GMT switch support for the CICS VR registered backup names list
- The CICS VR
VSAM sphere list secondary window contains a List pull-down menu which provides
a List backup names option. The dialog has been enhanced by adding support
for GMT or Local time format switches. This choice of times allows viewing
the actual names of the CICS VR registered backups for non- DFSMShsm backups,
with backup times in desired format. This facility is provided on the CICS VR
backup list secondary window only.
- Batch Backout
- Performance of the Batch Backout utility has been increased.
- Logstream names
- An option has been added, REALDDN, to use either real
DD names or generated names for the logstream of VSAM sphere changes.
- RCDS and DWW1558S message
- The message DWW1558S is no longer displayed incorrectly.
- Log stream copy utility enhancement
- Cursor control, TOD timestamp and delete functions have been added to
the log stream copy utility. You can use new keywords on the LOGSTREAMCOPY
command to:
- Set and reposition a “start of copy” cursor to control where log stream
records are read from.
- Repeat reads to produce additional exact copies of log stream records.
- Delete log stream records. Deletion is only permitted if the CICS VR global
default LCDEL is set to YES.
- Specify a TOD timestamp for the start and end of copying, which provides
more granularity than the existing keywords.
- Functional enhancements to the precopy exit
- The DEFEXIT command has been extended to provide greater compatibility
with older exit routines.
- Additional documentation is provided about the log stream records created
by the LOGSTREAMCOPY command.
