Add File Parameter
File The Adabas file number for which Adabas Fastpath optimization is to be defined.

Note:
By not specifying a file number, you can define a default parameter set for all files in a database (in this case only read-ahead optimization but not direct access optimization can be applied). Individual file parameters override a database default parameter.

in DBID The Adabas database in which the file to be optimized is located.
using SVC The Adabas SVC number.

Note:
Normally, the SVC parameter is only used at z/OS, MSP, and VSE/ESA sites where multiple Adabas SVCs are required; otherwise, it need not be used. If multiple SVCs are in use, all databases defined for optimization in the same buffer must use the same SVC as the buffer (and the Adabas System Coordinator hosting the buffer).

Time Window Optimization is only to be in effect within the specified time window. See parameter Start Time.

After a file parameter is added, the File Parameters Maintenance screen can be used to define further optimization parameters which are to be in effect for the file. This is described in the following section.

File Optimization Parameters

The following parameters can be maintained using this screen:

Parameter Description
Start Time, End Time

Optimization is only to be in effect within the specified time window. See parameter Start Time.

Note:
You can enable optimization for a different time window by creating a different parameter set for this file.

Update Sensitivity Indicates how Adabas Fastpath is to process commands which result in database updating. The following values are permitted:

N (none). Ignore all update commands.
R (record level). Remove data by identifying single records.
F (file). Remove all data for the file held in the Adabas Fastpath buffer.
D (distributed record level). Use only on advice from Software AG support.

Initial Status By setting this field to OFF, you can indicate that the file parameters being defined are not to be activated until this field is changed to ON.
Set Limit Adabas Fastpath creates sets of direct access command models. This parameter limits the size (in k) of data items within a set.

Set ID Length Limit
RB Length Limit
Set Concurrency

These parameters can be used to decrease (but not increase) the values of the equivalent buffer parameters. These parameters are described in section Adabas Fastpath Parameters.
Expanded File This field must be set to Y if the file is defined to Adabas as an expanded file. If so, direct access optimization cannot be defined for L3/L9 commands.
Cache secure file If the file is password protected, but direct access caching is still required, then set this parameter as ‘Y’. Use of secure file caching is not recommended.
Password for secure file D-A caching If the file is password protected and direct access caching is still required, and the cache secure file parameter is set to ‘Y’, then the password needs to be given here. Use of this parameter is not recommended.
Additional Encodings

The setting for direct-access optimization for data of a different character encoding from that used by Adabas to store the data internally. Settings:

  • Default: Inherit the buffer-level setting.

  • None: Only data for Adabas internal encodings.

  • All: All the possible encodings allowed by Fastpath.

  • Single byte ascii: This additional character encoding.

  • Single byte ebcdic: This additional character encoding.

  • Double byte ascii: This additional character encoding.

  • Double byte ebcdic: This additional character encoding.

Pacing: Controls the rate at which housekeeping is performed for this file.
Optimization Summary

The current direct access and read-ahead optimization settings for each Adabas command used for this file.

Optimization can be defined for the following commands:

  • direct access: L1,L3,L9,S1,S2

  • read-ahead: L1,L2,L3,L9,S1,S2,S8,S9

Note:
Sx commands are generally followed by L1 commands in order to retrieve subsequent records. Although it is the subsequent L1 commands that benefit from read-ahead optimization, control is through the initiating Sx command.

Use PF5 to commit all changes. Use PF3 to exit without applying any changes.

Use PF10 and PF11 to modify the direct access and read-ahead optimization parameters as described in the following sections:

Direct Access Optimization Parameters

Select Job Type

Name The control name.

Note:
For non-DTR and API types, the control name will be the same as the job name.

Note:
A control name can include one or more asterisks (*) to indicate a wild card. For example, the client runtime control for a type of BATCH with the name UK**E is found by any job with the name UK in positions 1-2 and E in position 5, no matter what the characters are in positions 3-4. If an asterisk (*) is the last character in a control name, the remainder of positions in the name through the eighth are padded with asterisks. Wilcards are not permitted for DTR or API types.

Type The job type. Each different job type has a different characteristic so it is important to select the correct type.

Note:
If you are using CICS/MRO with dynamic transaction routing, or CICSplex, you must select the job type (DTR - Dynamic transaction routing). The standard CICS job type is used for CICS/MRO without dynamic transaction routing or for other CICS environments.

Note:
If you mark the selection None of the above, another selection window appears with additional job types. If you need to use a job type from the second selection window, contact Software AG for advice.

Once you select a job type, a screen will ask for the job name. In this example, controls for a TSO type job are being defined.

Normally, the absence of client runtime controls for a job implies that optimization is not applied. Thus, you can implement optimization gradually by defining only specific jobs to receive optimization.

Alternatively, this can be reversed. Client runtime controls can be defined for default jobs so that optimization is applied to all jobs of a specific category. Then, you can specify only the jobs that are not to be optimized and those that differ from the default.

Note:
A specific job definition overrides any wild card job definitions or any default definition.

Maintaining Client Runtime Controls

To maintain client runtime controls, on the client runtime controls screen, enter the option code m next to the job for which parameters are to be maintained. In the sample screen shown below, the job parameters for batch job KM27WD are displayed.

The following screen will be displayed:

Detailed Client Runtime Controls

Parameter Description
FASTPATH ON/OFF If OFF is specified, Adabas Fastpath optimization will be not be performed for this job.
Job End Statistics If Y is specified, Adabas Fastpath performance information will be sent to the operator console when a job ends.
Direct Access If OFF is specified, no direct access optimization will be performed for the job, without regard to other parameters.
Read-Ahead Optimization Control If OFF is specified, no read-ahead optimization will be performed. In addition, you can choose between the read-ahead factor algorithms for TP monitors (TP) or for batch (BAT). While both algorithms accelerate the factor as the sequence length increases, the batch algorithm accelerator is faster than the one for TP monitors. Normally, the default setting is the most efficient.
Read-Ahead Memory Limit Used to restrict the memory allocated to the job for read-ahead optimization.

Specifying Overrides to Client Runtime Controls

Overrides to the base-level client runtime controls may be specified. This provides the possibility for a greater granularity of control, allowing controls to relate specifically to particulat logins, job steps or transactions.

Enter ‘O’ next to a job which already has AFP client controls in the Client Runtime Controls screen.

Note:
Not all job types will support overrides.

Then enter PF10 to add some client runtime control overrides.

The following screen will be displayed:

These runtime controls may be modified and saved using PF5.

In the Client Runtime Controls screen ‘Overrides’ will appear in the comments.

These overrides will now apply in preference to the base-level controls for the specific login, job step or transaction.
