that any user will experience will vary depending upon many factors, including
considerations such as the amount of multiprogramming in the user’s job stream,
the I/O configuration, the storage configuration, and the workload processed.
Therefore, no assurance can be given that an individual user will achieve results
similar to those stated here.

z/OS Connect EE vision statements
A unified end to end story for naturally RESTful APIs and z/OS subsystems
API composition
An API developer can create a natural REST API using a
selection of existing or new assets without being forced to write
any new code in single common tooling experience
API deployment
API deployment can be automated by extending an existing
enterprise change control process, or performed manually
API discovery
A standard user of the IBM APIM Portal can locate APIs hosted
in z/OS Connect using business relevant context and place them
under management without having to interact with any of the
provider systems

What’s in a URI ?
JSON-RPC style service vs. a “naturally RESTful” API (extreme example)
Basic service enablement
URI conveys service, maybe method,
payload can convey everything!
Create a new account
POST /orders/createAcc
BODY name(Fred), address(…
RESPONSE accNum=9999
Review status of an order
POST /orders/orderStatus
BODY accnum=9999,invoice=380Z
RESPONSE result=Stock 5 days
Delete an account
POST /orders/delAccount
BODY accnum=9999
RESPONSE result=OK
Modelling for naturally RESTful APIs
HTTP verb conveys operation, URI conveys
resource
Create a new account
POST /orders?name=Fred
BODY address(…
RESPONSE /orders?accnum=9999
HTTP status 200
Review status of an order
GET /orders?accnum=9999&invoice=380Z
BODY <none>
RESPONSE result=Stock 5 days
HTTP status 200
Delete an account
DELETE /orders?accnum=9999
RESPONSE <none>
HTTP status 200
POST
GET
DELETE

z/OS product runtime anatomy
Post-SMP/E install, setup,
and starting the server

z/OS Connect EE install anatomy
Post-SMP/E install + creation of product read/write file system
/usr/lpp/IBM/zosconnect/v2r0
 bin
 runtime
 lib
 com.ibm.zosconnect
 <zosconnect feature files>
 wlp
 etc
/var/zosconnect
Not quite ready for first use…
SMP/E maintained, read-only
Read-write

After post-install script “zconsetup”
 bin
 runtime
 lib
 wlp
 etc
 extensions
/var/zosconnect
 v2r0
 extensions
 zosconnect.properties
Post-install: Create USS symlink
After SMP/E install has completed, the post-install shell script
zconsetup is used to create the extensions folder as a symlink to
/var/zosconnect/v2r0/extension. This directory contains the
Liberty feature properties files used at run-time for both z/OS Connect,
and any additional Liberty product features (e.g. IMS mobile).
The target location of the extensions directory symlink is restricted to
being /var/zosconnect/v2r0.
The z/OS Connect EE administrator must create the
/var/zosconnect file system if it does not already exist.

Ready to create servers…

Creating server instances

Server instances
By convention, server instance directories are stored under
/var/zosconnect/servers. This location can not be modified (*Known limitation*).
Note: Server directories are entirely independent of the extensions symlink and service provider
properties files

Additional Liberty product features
 bin
 runtime
 lib
 wlp

 zoscon-SP

 imsmobile-v2
 <IMS SP
feature files>
 …
Additional product features
In this example, the IMS mobile service
provider for z/OS Connect V2 is a
Liberty product feature, maintained by
an IMS SMP/E install
.
Alternatively it could be a feature-
manager installed to a non-SMP/E
maintained location on the z/OS UNIX
file system.
Additional Liberty feature properties must
specify the absolute path to their folder
containing lib/<feature name>

A new pricing metric
Tiered, simultaneous
instance-based pricing

34
What about pricing?
It is IBM’s intention that z/OS Connect EE will introduce an
innovative new pricing model on z Systems.
“per instance” pricing metric
• Based upon the maximum number of active concurrent
address spaces
• Tiered usage bands
• provides increasing value as the size of an overall
deployment rises; low cost of entry for small projects
• Auditing is required through SMF89-2 records
• hourly snapshots of the number of concurrent
instances, reports created with utility IFAURP

35
What about pricing?
Value Unit exhibit VUE037 (from announcement letter ENUS215-493)
Number of
Simultaneous Instances
VUs per Simultaneous Instance
1 to 4 1 VU per Simultaneous Instance
5 to 10 4 VUs + 0.6660 VUs per Simultaneous Instance > 4
