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 the format that you require. 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.
