CA Technologies, Sr. Principal Software Architect
CA 1 and CA TLMS deliver tape data protection, library
management, and automation to typical z/OS organizations that
process thousands of tape files daily. In this session you will learn
the latest enhancements and features to maximize your current
tape management operations.

Agenda
 CA 1 Tape Management recent enhancements
– Audit Blockset Processing
– SMF Recovery Utility
– MSM Configuration Improvements
– Volume Pool Monitor
 CA TLMS Tape Management recent enhancements
– Read-only Subpools Support
3
CA 1 Audit Blockset Processing
Audit Blockset Processing – the problem
 To address a performance problem
– CA 1 customers with a very large number of DSNB updates have
performance problems which can impact tape processing.
 The apparent reason is a “bottleneck” updating the Audit File.
– The update of a single TMC record requires a reserve/release and at
least four I/Os to the Audit file.
 Adding a DSNB record can cause several updates to the TMC.
– While the Audit file is reserved, no other CPUs may update the Audit file
and likely the TMC.
5
Audit Blockset Processing – the solution
 BLOCKSET mode is a new optional feature which is activated
by a new Audit file format.
 The new Audit improves performance by reducing reserves
and updates of CTL#4, and by eliminating reserves
 This is done by assigning a block of audit records for an LPAR
to use rather than a single record. This means that CTL#4 will
be reserved and updated less often.
 Assigned block can only be updated by a single LPAR so there
is no need for reserves or reads before the records are written.
 Multiple time zones are now supported using GMT/UTC time
stamps.
6
CA 1 SMF Recovery Utility
TMSSMF Recovery Utility
 The TMSSMF utility allows for the recovery of CA 1 TMC
tracking information that was lost due to any circumstance in
which CA 1 was inactive.
 SMF must have been active recording Type 14 and 15 records
– Type 14 – The dataset was opened for INPUT or RDBACK
– Type 15 – The dataset was opened for OUTPUT, UPDAT, INOUT, or OUTIN
 Can use SMF log stream or data set recording:
– IFASMFDL used for dumping SMF log streams
– IFASMFDP used for dumping SMF data sets

CA 1 CSM Configuration Improvements
CA 1 CSM Configuration Improvements
 Several improvements to CA 1 Configuration
– Creation of TMC and Audit is now optional
– CA 1 System Options panels have been reorganized
– Fewer variables required for Configuration – 00 suffix is always used
– ABE parameter editing problem fixed
 Delivered as PTF RO52199
 Provides a new version of XML metadata used by
Configuration
 After applying PTF you must do new Deployment and
Configuration to see changes
14
CA 1 CSM Configuration – TMC / Audit Option
New option has been added to let you choose to create a new
TMC and Audit file or use your existing TMC and Audit file.
15
You will only be asked for TMC and Audit parameters if you
choose to build a new TMC and Audit file
16
If you choose to use your existing TMC and Audit you will just
be asked for the name of your TMC and Audit file.
17
CA 1 CSM Configuration – System Options
 CA 1 System Options are now grouped by function, similar
to ISPF grouping
 Some options will default to a best practice value, not the
documented default value.
18
CA 1 CSM Configuration – System Options
 The following parameters have been changed to a “best
practice” value instead of the CA 1 default
 The best practice value is only set by Configuration

CA 1 Volume Pool Monitor
Volume Pool Monitor
 Volume Pool Monitor (VPM) is an optional feature which provides a
new way to monitor tape activity for pools of CA 1 managed tapes.
 VPM uses a CTS subtask to monitor the status of volumes in user
defined pools and record their status in a VSAM data base.
 At intervals, the status of these pools are compared to user defined
rules and email/WTO “alerts” are sent if required.
 Model emails/WTOs are created and customized by the user. They
may contain “substitution variables” which can provide values for
the alert conditions.
 All information about pools, alerts, substitution variables, and the
options that control VPM reside in the VSAM data base (VDB).
21
Volume Pool Monitor - Features
The following are features of Volume Pool Monitor.
 User created volume pools and alerts.
 Display of volume pools via z/OS console or ISPF.
 Constant monitoring of volume pools via CTS task.
 Notification via email or WTO when “alert” conditions are met.
 Substitution variables which can be used in emails/WTOs and alerts.
 History records for volume pools which can be used in spreadsheets.
 Variables updated by CA 1 programs (TMSCLEAN, TMSCOPY, and
TMSVMUPD)
 CTS ISPF panels to maintain VPM

CA TLMS Read-only Subpool Support
CA TLMS Read-only Subpool Support
 Read-only Subpools Support
 Published as PTF RO47472 in Sept 2012
 Use to protect a volume or range of volumes from being
written to (typically copies of volumes at a remote site)
– Users cannot use a disposition of MOD to append to an existing dataset.
– Existing datasets cannot be recreated.
– Secondary files cannot be added to a volume owned by this pool.
– Output processing is prevented.
 This capability is needed for the IBM TS7700 VTS Dual Copy
feature and other virtual tape solutions that allow replication.
27
Summary
 CA 1 and CA TLMS continue to add new
features and enhancements to simplify
and reduce the administration of tapes
and virtual tapes, providing a
comprehensive end to end management
