Criteria Manager
The TDWC provides a web-interface to list, create, mantain and
activate SAP Criteria Profiles
© 2011 IBM Corporation
Criteria selection
TWS connects to SAP server and shows the criteria profiles already created.
A menu bar helps the user in maintaining objects.
© 2011 IBM Corporation
Action and Display on Criteria Profiles
User easily selects action on object and by clicking, the definition is displayed.

Event Interception and Relaunch Criteria
On Interception Event type, a Job Relaunch Criteria is made available. This allows the user
to define the policy for release intercepted job, through TWS control.
© 2011 IBM Corporation
Define Relaunch policy
The Job Relaunch Criteria allows the user to let TWS schedule the intercepted jobs,
extending to XBP3.0 the same TWS feature already available in XBP 2.0 configuration.
By scheduling this Job Collector,
TWS will release all the intercepted
SAP jobs that satisfy the Relaunch Criteria
given that profile ID.

Modeling TWS for SAP jobs on Z/OS from TDWC
TDWC allows now also TWS user for zOS to define and mantain TWS for SAP jobs: R/3 jobs, Process Chain
And infoPackage, same as the Distributed capabilities.

Restart a Process Chain
Four TWS actions are available
on a selected process chain.

Creating a SAP job from TDWC
TDWC allows now the user to define a SAP connection and to start creating new SAP job within
the TWS console.
© 2011 IBM Corporation
SAP job modeling by selection
User can design a SAP job in the same way it uses to do on SAP GUI. ABAP list selection,
External Command and External Program are supported.

Single-click TWS-SAP integration
Once the new SAP job is created from TDWC, the user in a single click can link it to a new TWS
For SAP job definition.

List of Spool Requests
 Up until Tivoli Workload Scheduler for Applications V8.5, the only option you had to check the
spool request of an R/3 job was through its job log
– Performance degradation during job log retrieval for very huge spool request
– Some difficulties to identify, navigate, analyze the spool request of a particular r3 job step
 Tivoli Workload Scheduler for Applications V8.6 enables you to browse the spool request of a
job more easily
– A new Dynamic Workload Console action is provided for executed Standard R/3 Job in the
“Monitor Jobs” task, a “Show Spool List” action has been added to the “More Actions” pulldown menu
– A list of Spool Request details is shown for every step in the R/3 job
– Each Spool Request can be analyzed separately
– A set of pages is loaded when a Spool Request is analyzed
– You can navigate among a set of pages, go directly to the last or first set of pages

Application Job Log
In the Job definition window the user can enables the retrieval and appending of the
SAP application log to the Job log of Tivoli Workload Scheduler.

Application Return Code
In the Job definition window the user can enables or disables the mapping of the SAP application return
code to the Tivoli Workload Scheduler return code. If the SAP job contains several steps, it takes the greater
RC code from the step list

Support SAP Secure Network Communication (SNC)
 SAP offers a software layer to integrate security products at application level. With SNC, you
can secure an RFC connection between communication partners like Tivoli Workload
Scheduler for Applications access method and the SAP System.
Tivoli Workload Scheduler for Applications 8.6 was extended to read SNC configuration
parameters and forward them to the SAP RFC communication layer used during logon to the
SAP system.
Tivoli Workload Scheduler for Applications 8.6 does not provide or ship SNC software, it
enables to use 3rd party SNC products to secure the RFC communication.
 The following new options are added to the workstations options file:
– r3sncmode
enable / disable SNC for RFC
– r3sncpartnername target SAP Systems SNC name
– r3snclib
full path and filename to the 3rd party SNC library
– r3sncqop
quality of protection
– r3sncmyname
own (local) SNC name

FIPS Compliance
Federal Information Processing Standard (FIPS) is a U.S. government computer security standard
used to accredit cryptographic modules.
FIPS 140-2 accreditation is required for for cryptographic modules produced by private sector
vendors who seek to have their products certified for use in government departments and regulated
industries.
Implementation
- new parameter use_fips that enables r3batch to use FIPS compliant algorithm for
password encryption
- enigma tool now is using FIPS compliant algorithms for password encryption
- network communication between r3evmon and TWS engine now supports
encryption mechanism with OPENSSL and FIPS compliant libraries (gskit version
8).

SAP PI Channel
TWS provides also a Job Executor Plugin to pilot SAP PI channel status.

TDWC Job Plugin PI Channel
The TWS Job log contains also
the job details about execution
and actual status.

SAP Temporary Variant

The temporary variant is created for the job and deleted once the job has finished

The temporary variant lifecycle is managed by SAP

Tivoli Workload Scheduler for Applications V8.6 and DWC V8.6 FP1 enable you to
define/assign/modify a temporary variant through the dynamic R/3 job definition (task string)
© 2011 IBM Corporation
SAP Temporary Variant cont.

Examples
1. A temporary variant is created using the information indicated in the expression
•
The following example shows how you can create a temporary variant with the information
specified in the expression and assign it to step 2
-vpar2 <parameter_name>=<parameter_value> ... –vsel2
<selection_option_name> ... –vtemp2
2. Assign a temporary variant to the specified step number
•
The following example shows how you can assign a variant to step number 1.
The temporary variant must exist
-v1 <temporary_variant_name> -vtemp1
3. The value for a temporary variant that already exists is substituted with the value
indicated in the expression
•
The following example shows how you can substitute the value of a temporary variant that must
already exist with a value specified in the expression and assign it to step 5.
The temporary variant must exist, otherwise, the expression returns an error.
-v5 <temporary_variant_name> -vpar5 <parameter_name>=<parameter_value> ...
–vsel5 <selection_option_name> ... –vtemp5

Improve r3batch performance
 Introduction of the rfc_interval keyword in the R/3 common options file to optimize
performance:
– When operating through the DWC
• Browsing for and selecting SAP jobs from a list
• Editing SAP jobs
• Raising/managing SAP events
• Managing SAP Criteria Profiles
– During SAP job submission and tracking
 Using the default value for the option, performance has been optimized by 50% for the above
operations and for SAP jobs with a short duration.
 Decreasing the value for the option, the performance could be higher but CPU consumption on
the r3batch system is high. If you experience performance or CPU consumption issues, you
may try to change the value accordingly

Keep SAP jobID synchronized
Using the Dynamic Workload Console, you can define a Tivoli Workload Scheduler job that runs
a SAP job. The SAP job can already exist in the SAP System or can be created as new job
using the DWC

In previous releases if the user edited the SAP job modifying either the Target Host, the job
class or adding or deleting steps the JobID was automatically replaced forcing the user to
manually update all jobstreams containg the modified SAP job

With the new Tivoli Workload Scheduler for Applications V8.6 release, for any SAP job
modifications, the JobID remains unchanged maintaining the synchronization with the job in
the SAP System
© 2011 IBM Corporation
Keep SAP jobID synchronized
In the new Tivoli Workload Scheduler for
Applications V8.6 release, for any change
the Job ID remains unchanged.
In this way the User is not forced to modify
any jobstream after a SAP job
modifications
