Adabas Transaction Manager Version 8.1.2 is compatible with the following operating systems:
z/OS
z/VSE
BS2000
Adabas Transaction Manager Version 8.1.2 can be used with databases running under any supported level of Adabas Version 7.4 or above.
Note:
If you are using Adabas Version 8.1.1, ensure that the following
Adabas fixes are applied: AO811002, AN811021, AN811023, AN811024.
Using Adabas Transaction Manager Version 8.1 with Adabas Version 8.1 could not be more simple. Use the ADA81x load library along with the ATM81x and COR81x libraries.
Using Adabas Transaction Manager Version 8.1 with Adabas Version 7.4 in z/OS systems requires an additional library (currently, Adabas 7.4 LX08) in some cases, to enable various DTP capabilities within the product. The table below clarifies the use of libraries for the various components:
DTP=TM (Transaction
Manager)
|
DTP=RM (Resource
Manager)
|
DTP=NO (Non-RM
Database)
|
|
| Classic Adabas |
ATM81x |
ATM81x |
ATM81x |
| Adabas Cluster Services | Not permitted |
ATM81x |
ATM81x |
| Adabas Parallel Services | Not permitted |
ATM81x |
ATM81x |
In the above table, “LX” indicates that you should concatenate the LX08 library ahead of the ADA74x library in the STEPLIB of the job’s JCL.
When a component is converted from Adabas 7.4 to Adabas 8.1 you must stop using the LX library for it.
Before you use the LX library for the first time with a Cluster Services or Parallel Services database, you should run the ADACNV utility which is supplied in the LX library, specifying the following as DDKARTE input:
ADACNV CONVERT TOVERS=75
If you subsequently revert to using the standard Adabas 7.4 library,
either because the cluster is now to be run with DTP=NO,
or because the database is no longer to execute as part of a cluster, you
should convert the database back to standard version 7.4 format by running
ADACNV, as supplied in the LX library, with the following DDKARTE input:
ADACNV CONVERT TOVERS=74
Caution:
Failure to follow the above instructions can result in various
problems relating to the PPT area of the Associator dataset.
The Transaction Manager (DTP=TM) may not be run
under Adabas Version 7.4; it must be run under Adabas Version 8.1.
DTP=RM databases may run under Adabas Version
7.4.
Adabas Parallel Services databases running under Version 7.4 must run
with DTP=NO. If you want an Adabas Parallel Services
database to run with DTP=RM, it must run under Version
8.1.
This section provides an overview of the required Adabas data sets when using Adabas Transaction Manager.
The following table shows the dataset definitions that are essential for correct execution of the ATM transaction manager. Other datasets, such as command log, may be specified. For details of these, refer to the Adabas documentation.
| Dataset | Link Name | More Information |
|---|---|---|
| Load library |
ADA74x library or ADA81x library; COR81x library, ATM81x library Note: |
|
| Associator | DDASSORn | |
| Data Storage | DDDATARn | |
| Work | DDWORKR1 | |
| ATM log | ATMLOG1/2 | Optional, depending on TMLOG parameter value. |
| ADARUN parameters | SYSDTA/ DDCARD | DTP=TM, and other
operational parameters.
|
| ADARUN messages | SYSOUT/ DDPRINT |
The following table shows the dataset definitions that are essential for correct execution of a single database or cluster that is to execute as a resource manager, under the transactional control of ATM. Other datasets, such as command log, may be specified. For details of these, refer to the Adabas documentation.
| Dataset | Link Name | More Information |
|---|---|---|
| Load library |
ADA74x library or ADA81x library; COR81x library, ATM81x library Note: |
|
| Associator | DDASSORn | |
| Data Storage | DDDATARn | |
| Work | DDWORKR1 | |
| Work part 4 | DDWORKR4 |
Recoverable information about global transactions. Note: |
| ADARUN parameters | SYSDTA/ DDCARD | DTP=RM, and other
operational parameters

Adabas Transaction Manager Version 8.1.2 requires that you first install the Adabas System Coordinator Version 8.1. Refer to the Adabas System Coordinator documentation for more information.
A supported version of Entire Net-Work is required for communication between Adabas Transaction Manager instances in different system images. Refer to the Entire Net-Work documentation for more information.
Natural is required by the Online Services application SYSATM.
Any supported level of Natural Version 4.1 or above can be used. Refer to the Natural documentation for more information.
The Adabas Transaction Manager client proxy currently supports only one Adabas SVC per client session under Com-plete.
For cross-vendor coordination of distributed transactions, Adabas Transaction Manager supports the following IBM asynchronous exit drivers: RRMS and CICS Syncpoint Manager.
