This section describes the preparation for and installation of Adabas Parallel Services on z/VSE systems.
The installation procedure outlined in this section corresponds to the jobs that SMA creates to install the product.
The Adabas Parallel Services installation tape is a standard label tape. Refer to the Report of Tape Creation that accompanies the tape for the volume serial number, density, media type, data set names, and data set sequence numbers.
The tape contains the installation data sets, a data set required by SMA, and one or more data sets containing maintenance fixes. Refer to Zap Information for information about applying fixes.
Note:
If you are using System Maintenance Aid (SMA), refer to the
System Maintenance Aid documentation. If you are not using
SMA, follow the instructions below.
This section explains how to copy the data sets .LIBJ,
.LIBR and .LICS from tape to disk. All other data
sets can be installed directly from the tape.
You will then need to perform the individual installation procedure for each component to be installed.
The data set COPYTAPE.JOB contains the JCL required to copy
the data sets .LIBJ, .LIBR and .LICS
from tape to disk. Copy COPYTAPE.JOB to your disk by using the
following sample JCL:
* $$ JOB JNM=LIBRCAT,CLASS=0, + * $$ DISP=D,LDEST=(*,UID),SYSID=1 * $$ LST CLASS=A,DISP=D // JOB LIBRCAT * ***************************************** * STORE COPYTAPE.JOB IN LIBRARY * ***************************************** // ASSGN SYS004,nnn // MTC REW,SYS004 // MTC FSF,SYS004,4 ASSGN SYSIPT,SYS004 // TLBL IJSYSIN,'COPYTAPE.JOB' // EXEC LIBR,PARM='MSHP; ACC S=lib.sublib' /* // MTC REW,SYS004 ASSGN SYSIPT,FEC /* /& * $$ EOJ
where:
nnn is the tape
address
lib.sublib is the library and
sublibrary in which COPYTAPE.JOB is to be stored
Modify COPYTAPE.JOB according to your local naming
conventions and set the disk space parameters.
Submit COPYTAPE.JOB to copy the data sets .LIBJ,
.LIBR and .LICS from tape to your disk.
Adabas Parallel Services users must define an additional sublibrary in the Adabas library for the Adabas Parallel Services components.
A sample job to accomplish this is as follows:
// JOB ASMDEF DEFINE NON-VSAM SUBLIB // OPTION LOG // DLBL SAGLIB,'ADABAS.Vvrs.LIBRARY',2099/365,SD // EXTENT SYS010 // ASSGN SYS010,DISK,VOL=vvvvvv,SHR // EXEC LIBR DEFINE S=SAGLIB.ASMvrs REUSE=AUTO R=Y LD L=SAGLIB OUTPUT=STATUS /* /&
where:
| SYS010 | is the logical unit for the Adabas library |
| vvvvvv | is the volume for the Adabas library |
| vrs | is the Adabas version/revision/system maintenance (SM) level |
A sample job to restore the Adabas Parallel Services components is as follows:
// JOB ASMRST RESTORE NON-VSAM // OPTION LOG // ASSGN SYS006,cuu // PAUSE MOUNT ADABAS INSTALL TAPE cuu // MTC REW,SYS006 // MTC FSF,SYS006,tt // DLBL SAGLIB,'ADABAS.Vvrs.LIBRARY' // EXTENT SYS010 // ASSGN SYS010,DISK,VOL=vvvvvv,SHR // EXEC LIBR RESTORE SUB=SAGLIB.ASMvrs - TAPE=SYS006 LIST=Y R=Y LD SUB=SAGLIB.ASMvrs OUTPUT=NORMAL /* // MTC REW,SYS006 /&
where:
| SAGLIB | is the Adabas library name |
| SYS010 | is the logical unit for the Adabas library |
| SYS006 | is the Adabas installation tape |
| cuu | is the physical unit address of the tape drive |
| tt | is the number of tape marks to space forward (see the Report of Tape Creation) |
| vvvvvv | is the volume for the Adabas library |
| vrs | is the Adabas version/revision/system maintenance (SM) level |
Make any needed additions and modifications to the ADACOM member.
Read ADACOM Initialization Parameters for more information about specifying values for ADACOM parameters.
An ADACOM initialization task is provided. This task must be active on the operating system image before any Adabas Parallel Services cluster nucleus is started.
ADACOM allocates the nucleus table for monitoring the active nuclei and the user table for monitoring users in the SVA above the 16MB line.
The following is a sample job for running ADACOM:
// JOB ADACOM //*-------------------------------------------------------------* //* ADABAS PARALLEL SERVICES ADACOM Vv.r.s STARTUP * //*-------------------------------------------------------------* // LIBDEF PHASE,SEARCH=(SAGLIB.ASMvrs,SAGLIB.ADAvrs) // EXEC ADARUN,SIZE=ADARUN ADARUN PROG=ADACOM /* ADACOM SVC=sv1,DBID=dbid1,NU=150 ADACOM SVC=sv1,DBID=dbid2,NU=150,F=Y ADACOM SVC=sv2,DBID=dbid1,NU=500 ADACOM SVC=sv2,DBID=dbid3,NU=500 /* /&
Note:
ADACOM must run in a dynamic partition.
To create a startup procedure for each cluster nucleus, complete the
following steps:
Customize a startup procedure to execute ADARUN.
For each Adabas cluster nucleus, customize the appropriate startup parameters and execute ADARUN from the Adabas load library.
Note:
Each Adabas cluster nucleus must run in a dynamic
partition.
Concatenate the Adabas Parallel Services load library ahead of the Adabas load library in the LIBDEF PHASE SEARCH statement.
Allocate and format a Work data set for each nucleus.
All nuclei in an Adabas Parallel Services cluster share a common database resource; i.e., the same ASSO and DATA data sets. Each nucleus in the cluster must have its own Work data set; and all Work data sets within a cluster must have the same size and device type as defined in the general control block (GCB).
Specify for each nucleus the ADARUN parameters CLUSTER, NUCID, CLUCACHESIZE, CLULOCKSIZE, and CLUCACHEUNCHANGED.
Although each nucleus of an Adabas cluster shares the same database resource (DBID), each nucleus must have a unique NUCID value:
a single (noncluster) nucleus: NUCID=0 (default)
a cluster nucleus: NUCID=1-65000
Values for the CLUCACHESIZE and CLULOCKSIZE parameters are required for allocating the global data spaces. Read Performance and Tuning.
Use current values for all other ADARUN parameters, then reevaluate the values after monitoring the result. Ensure that each nucleus in the cluster is prepared to handle the entire workload for the common database, if necessary.
If protection logs are used, they must be dual or multiple logs and each nucleus must have its own. If one nucleus in the cluster runs with PLOGs, all nuclei in the cluster must run with PLOGs. The ADARUN PLOGRQ parameter must be the same for all nuclei (global parameter). If user exit 2 or user exit 12 is supplied for one nucleus, the same user exit must be supplied for all nuclei in the cluster.
If command logs are used, each nucleus must have its own. If command logs are to be merged, they must be dual or multiple command logs and each nucleus in the cluster must have the same CLOG definition. To invoke automatic CLOG merging, CLOGMRG=YES must be specified in the ADARUN parameters or given as an operator or AOS/ADADBS command to any nucleus in the cluster.
The following sample JCL executes the Adabas ADARUN program to implement session parameters for an Adabas Parallel Services cluster nucleus.
Note:
The Adabas Parallel Services library is concatenated ahead of the Adabas library in
the LIBDEF PHASE SEARCH statement.

To start Adabas Parallel Services, complete the following steps:
Start the ADACOM initialization task on the operating system image that is hosting the Adabas Parallel Services cluster environment.
Start the Adabas Parallel Services cluster nuclei in any order.
The Adabas Parallel Services cluster is now ready to process user requests.
Rules for subsequent starts of Adabas Parallel Services are described in Restart/Recovery Processing .
