ES Control

General

SEPs: Displays the number of concurrent service execution processes currently supported by this server. You can change the number by entering a value in the field.
Force Phase In: Check this to have MSS reload programs each time they are invoked. This applies only to programs that are not marked resident and have not been loaded with the hold attribute.
Admin SEPs: The number of Admin SEPs defined.
Initial Transaction: The transaction to run when a TN3270 session connects to the server.
HTTP Out: Displays the size of the data blocks passed across shared memory for HTTP output. You can change the HTTP size by entering a value in the HTTP Size field.

Timeouts

ID: Displays the time in minutes that the system will allow an ESMAC or TN3270 client session to remain idle before session timeout. At system startup, this is initialized to the value specified in the System Initialization Table. A value of 0 indicates that there is no timeout.
Note: If you change the value, the change will not be saved at system shutdown.
Runaway: Displays the maximum continuous period of time in seconds that the region will allow a transaction to run without making an API call. When this value is exceeded, the transaction is abended. At system startup, this is initialized to the value specified in the System Initialization Table. A value of 0 indicates that there is no timeout.
Note: If you change the value, the change will not be saved at system shutdown. You can override this value for an individual transaction through the relevant Program Control Table entry.
Input: Displays the maximum time in seconds allowed for operator response to an explicit CICS RECEIVE command before the transaction is abended. At system startup, this is initialized to the value specified in the System Initialization Table. A value of 0 indicates that there is no timeout.
Note: If you change the value, the change will not be saved at system shutdown. You can override this value for an individual transaction through the relevant Program Control Table entry.
Deadlock: Displays the maximum time in seconds that the region will permit an application to wait for a resource that has been locked by another process. At system startup, this is initialized to the value specified in the System Initialization Table. A value of 0 indicates that there is no timeout.
Note: If you change the value, the change will not be saved at system shutdown. You can override this value for an individual transaction through the relevant Program Control Table entry.

Diagnostics

DUMP: Click this to initiate a dump. Dump information is stored in the data set identified by Active Dump DS. If you do not initiate a dump using DUMP, dumps occur when the system and/or transaction abends, or if the program executes the EXEC CICS DUMP command. A dump will occur on an abend only if Sys and/or Tran is checked in the Dump On ABEND group.
SWITCH DUMP SET: Click this to switch between the A and B data sets that are used to store dump information.
SWITCH TRACE SET: Click this to switch between the A and B data sets that are used to store trace information.
Size: Displays the maximum size of the auxiliary trace and dump file in kilobytes. A value of 0 (zero) means that there is no maximum size. You can change the size by entering a value, in kilobytes, in the Diagnostic Size field. The maximum size you can enter in this field is 999999 kilobytes.
Dump Count: Displays the number of dumps that have occurred.
Trace Active: If checked, the in-memory trace data is transferred to the auxiliary (diagnostic) data set at the roll-over of the system trace table.
Trace: Displays the current data set used for trace information.
Blocks: Displays the number of blocks of trace information captured.
Dump on ABEND Sys: Check this to indicate that MSS should produce a dump if an abend occurs in its own code.
Dump on ABEND Tran: Check this to indicate that MSS should produce a dump if an abend occurs in any of your transaction programs. If you check this field, you can control whether or not a dump is produced for an individual program by checking or unchecking Dump on ABEND on the PCT properties dialog box. If you leave this field unchecked, MSS ignores the setting of Dump on abend on the PCT properties dialog box.
Debugger: Check this to enable dynamic debugging.

HSF Data

SWITCH: Clicking the SWITCH button will switch collection to the alternate .csv file before the active file has reached the maximum size.
Enable HSF Collection: Check this to switch on HSF processing.
Write to Disk: Enables writing of HSF records to comma-separated files. These are called cashsf-a.csv and cashsf-b.csv, and are written to the system directory. Only one file is written to at any one time - this is called the active file. You write to the active file until you click SWITCH or the active file reaches the maximum size, at which point the alternate file becomes active. If the alternate file already exists it will be backed up with the name cashsf.nnn where nnn is the number of the backup.; When you start an enterprise server, cashsf-a.csv is always set as the active file, and if it already exists it is backed up. Backup extensions are numbered from .001 up to .999. When a backup with extension .999 exists then the next backup will be created as cashsf.001. If cashsf.001 already exists then it will be overwritten.
Max HSF Size: If you have checked Write to Disk, this is the size in kilobytes that the .csv file will reach before Enterprise Server switches to the alternate .csv file. A value of 0 selects the maximum size possible (4 Gb).
Active HSF set
Number of ESMAC Records: Displays the number of HSF records that Enterprise Server will hold in memory. When this number is reached, older records will be deleted when a new one is created. In addition, records older than one hour are deleted. The minimum value is 0 (no HSF data is displayed), the maximum is 4096.
Create JCL File Records: Check this to switch on the generation of JCL file (JCLF) records for mainframe files, such as those that are accessed with FCDCAT and ASSIGN(EXTERNAL). JCLF records are local to a step, so that multiple records can be generated for a single data set name in the same job - one record is created for each step in which the data set is accessed.

Trace

Displays the currently set trace points. The trace points displayed are those that have been set by the SIT. You can change individual trace points by checking each trace point required, or you can click All to check all trace points.

Note: This overrides the trace points set by the SIT. Any changes you make are effective at the point you click APPLY. The changes are lost the next time the server is initialized.

Memory Strategy

Use this diagnostic feature to control the frequency and type of runtime memory validation, as well as specifying the processes to which these settings apply. You use this facility to help track down memory violations and corruptions. Unless you are directed otherwise by SupportLine, Micro Focus recommends that you use only the default settings, which result in the most efficient use of memory. Setting these values inappropriately might result in a degradation of system performance and excessive memory usage.

Using invasive settings in a development or user acceptance environment might be acceptable and even desirable, but you should use caution when used in a production environment. You set the desired memory strategy at the time you wish to diagnose a particular problem, and reset the strategy when the diagnosis is complete.
