Review the Report of Tape Creation that accompanies the release package before restoring the release data to disk.
The installation tape contains the following data sets in the sequence indicated in the report:
| Data Set | Contents |
|---|---|
| ATMvrs.JOBS | Installation jobs, utility jobs |
| ATMvrs.MOD | Executable modules |
| ATMvrs.INPL | Online Services application |
| ATMvrs.ERRN | Online Services messages |
where vrs is the version, revision, and system maintenance level of the product.
The Adabas System Coordinator must be installed prior to the installation of Adabas Transaction Manager. See the Adabas System Coordinator documentation for detailed information.
Once the required System Coordinator components have been installed, you can proceed to install Adabas Transaction Manager. The following checklist identifies the steps necessary to complete the installation:
| Step | Description |
|---|---|
| 1 | Copy the Tape Contents to a BS2000/OSD Disk |
| 2 | Prepare SYSATM |
| 3 | Enable the client process |
| 4 | Enable the database process for two-phase commit |
| 5 | Prepare the recovery file |
| 6 | Enable the Transaction Manager to run as a Service within Adabas System Coordinator daemons |
| 7 | Verify the installation |
Following is the general Adabas Transaction Manager installation procedure. The actual installation depends on your particular requirements and the specific contents of the release package provided by Software AG for your site. Information in the release package is intended for your system. If that information differs from the information in this section, use the release package information or contact Software AG technical support for assistance.
To copy the tape contents to a BS2000/OSD disk:
Copy the library SRVnnn.LIB from tape to disk.
This action is not necessary if you have already copied the library SRVnnn.LIB from another Software AG tape. For more information, refer to the element #READ-ME in this library.
The library SRVnnn.LIB is stored on the tape as the sequential file SRVnnn.LIBS containing LMS commands. The current version nnn can be obtained from the Report of Tape Creation. To convert this sequential file into an LMS-library, execute the following commands:
/IMPORT-FILE SUPPORT=*TAPE(FILE-NAME=SRVnnn.LIBS, - / VOLUME=<volser>, DEV-TYPE=<tape-device>) /ADD-FILE-LINK LINK-NAME=EDTSAM, FILE-NAME=SRVnnn.LIBS, - / SUPPORT=*TAPE(FILE-SEQ=9), ACC-METH=*BY-CAT, - / BUF-LEN=*BY-CAT, REC-FORM=*BY-CAT, REC-SIZE=*BY-CAT /START-EDT @READ ’/’ @SYSTEM ’REMOVE-FILE-LINK EDTSAM’ @SYSTEM ’EXPORT-FILE FILE-NAME=SRVnnn.LIBS’ @WRITE ’SRVnnn.LIBS’ @HALT /ASS-SYSDTA SRVnnn.LIBS /MOD-JOB-SW ON=1 /START-PROG $LMS /MOD-JOB-SW OFF=1 /ASS-SYSDTA *PRIMARY <tape-device> = device-type of the tape, e.g. TAPE-C4 <volser> = VOLSER of tape (see Report of Tape Creation)
Copy the procedure COPY.PROC from tape to disk
Call the procedure P.COPYTAPE in the library SRVnnn.LIB to copy the procedure COPY.PROC to disk:
/CALL-PROCEDURE (SRVnnn.LIB,P.COPYTAPE), - / (VSNT=<volser>, DEVT=<tape-device>)
If you use a TAPE-C4 device, you can omit the parameter
DEVT.
Copy all product files from tape to disk
Enter the procedure COPY.PROC to copy all Software AG product files from tape to disk:
/ENTER-PROCEDURE COPY.PROC, DEVT=<tape-device>
If you use a TAPE-C4 device, you can omit the parameter
DEVT. The result of this procedure is written to the
file L.REPORT.SRV.
The Adabas Transaction Manager Online Services (SYSATM) objects are delivered on the Adabas Transaction Manager distribution tape.
To prepare SYSATM:
Use your everyday Natural INPL job to load the administration tool (Natural application SYSATM) and associated message texts into your Natural system. For reference a sample Natural INPL job called CORI061 can be found with the sibling System Coordinator product in the jobs distribution file. The INPL job’s work file 1 must reference the distribution file ATMvrs.INPL and work file 2 must reference ATMvrs.ERRN.
Note:
If you use Natural Security in this system, define the libraries
SYSATM and SYSMTvrs (where vrs is the level you are installing, for
example 821) and protect as you require. You may define MENU as the startup
transaction for SYSATM. However, you must not define a startup transaction for
SYSMTvrs.
Use the following parameter to define the Natural session where SYSATM is to be used:
LFILE=(152,dbid,fnr<,passw><,ciph>)
where dbid and fnr define the location of the Adabas System Coordinator configuration file.
Alternatively, assemble the Natural parameter module with
NTFILE,ID=152,DBID=dbid,FNR=fnr
To enable the Adabas Transaction Manager client process:
For the Adabas System Coordinator:
make the modified Adabas link module available (BLSLIBnn);
make the generated configuration module CORCFG available (BLSLIBnn); and
make the Adabas System Coordinator load library available (BLSLIBnn).
For Adabas Transaction Manager:
make the Adabas Transaction Manager load library available (BLSLIBnn).
For each Client:
refer to the section Client Runtime Controls for details on how to define the necessary runtime controls to enable a client for transaction management.
To enable the Adabas Transaction Manager database process for
two-phase commit:
For the Adabas System Coordinator:
make the Adabas System Coordinator load library available (BLSLIBnn).
For Adabas Transaction Manager:
set the Adabas parameter ADARUN DTP=RM.
include a DD statement for DDWORKR4.
Ensure this identifies a suitable WORK dataset which is allocated and formatted in the same way as the main WORK data set. In the case of a Cluster Services or Parallel Services database, the WORK 4 dataset is shared by all members of the cluster.
Important:
For details about the WORK4 dataset, including information
about sizing, please refer to the Adabas documentation, under
Defining an Adabas Database, which is part of
Database Maintenance Tasks in the section DBA
Tasks.
make the Adabas Transaction Manager load library available (BLSLIBnn).
Note:
An unmodified ADALNK must be available to the database in preference
to the ADALNK created during the installation of the Adabas System Coordinator.
All recovery information is maintained in a single direct access file defined to the Adabas System Coordinator daemon where the transaction manager service runs. The recovery file is shared by all transaction managers operating in the same Adabas System Coordinator group. For reference a sample formatting job called CORI040 can be found with the sibling System Coordinator product in the jobs distribution file. Change the parameters in this sample job with the following considerations:
"dsname" (file name)
Specify the file name, for example SAG.ATMvrs.cor-group-name.TMRFI
"nn" (file size in cylinders) and "@@@@" (device type)
The minimum block size of the file must be 4096 bytes, and we recommend a minimum size of 13,500 blocks for each transaction manager sharing the file. With reference to the Adabas Device Types and Block sizes section of the DBA Reference Summary, calculate how many cylinders are required for this many blocks based on the device type(s) available at your site. For example, when formatting a file assigned as a WORK component (as defined in the sample job), 13,500 blocks equates to 100 cylinders (nn) when using a 3390 device type ("@@@@").
Note:
It is very important that all transaction managers operating within
the same Adabas System Coordinator group share the same
recovery file.
To enable the Transaction Manager to run as a Service within Adabas
System Coordinator daemons:
set PRODUCT=ATM in the parameter input of
each System Coordinator daemon within which you wish to run the Transaction
Manager.
Important:
See the section Parameters for a description of all
runtime parameters which affect Transaction Manager operation. These runtime
parameters must be prefixed with ‘ATM’ when defining them in the parameter
input of the System Coordinator daemon within which the Transaction Manager is
operating.
make the Adabas Transaction Manager load library available (BLSLIBnn).
refer to the section Prerequisites...Adabas System Coordinator for information on the System Coordinator daemon dataset definitions necessary for the correct operation of the Transaction Manager.
Use the procedure described in section Verifying the Installation to ensure that the installation has been successful.
