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.
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.
To modify client runtime controls, on the client runtime controls

|---|---|
| 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. |
| Maximum read-ahead unit size (k) | Used to restrict the memory allocated for a single read-ahead operation. |
| Maximum read-ahead rate | Used to restrict the number of records processed in a single read-ahead operation. |

One of the following options may be selected:
Note: |
| Maximum Records | The number of records (up to 16) to be kept on file for end-of-job statistics. |
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 particular logins, job steps or transactions.
