IEASYSxx.ini

The IEASYSxx.ini files contain the values for some system configuration parameters, including the suffixes for some other configuration files. The suffixes for the IEASYSxx.ini files are specified in the SYSPARM parameters in the LOADxx.ini and IEASYMxx.ini files as well as the -sysp command line parameter. The IEASYS00.ini file is always read by the Tachyon Operating System before any other IEASYSxx.ini files.

Parameter lines can start in any column. More than one parameter definition is allowed on each line. If more than one definition is specified, each must be separated by a comma. In addition to parameter definitions, each IEASYSxx.ini file may contain blank lines and comment lines. Comment lines are any lines containing an asterisk as the first non-blank character. In addition, if a blank follows a parameter definition any subsequent characters on the line are treated as comments.

All of the parameter values in IEASYSxx.ini files may be overridden by the -parms command line parameter.

Each parameter definition begins with the parameter name followed by an equal sign (=) and then the parameter value. The parameters are:

BCP

The BCP parameter specifies the level of the Base Control Program to be set in various operating system control blocks. If not set, the default value is JBB1326. Changing the BCP level does not change the behavior of the Tachyon Operating System. The only effect of changing the BCP level is to set various flags which are often tested by applications to determine the available services. The accepted values are one of the following FMIDs:

MVS/370		MVS/XA		MVS/ESA		OS/390		z/OS
FMID	Release	FMID	Release	FMID	Release	FMID	Release	FMID	Release
JBB1326	3.2.6	JBB2110	1.1.0	HBB3310	3.1.0	HBB6601	1.1	HBB7705	1.2
JBB1327	3.2.7	JBB2133	1.3.3	JBB3311	3.1.1	JBB6602	1.2	HBB7706	1.3
JBB1328	3.2.8	JBB2214	2.1.4	JBB3313	3.1.3	HBB6603	1.3	HBB7707	1.4
JBB1329	3.2.9	JBB2216	2.1.6	HBB4410	4.1.0	JBB6604	2.4	HBB7708	1.5
		JBB2220	2.2.0	HBB4420	4.2.0	HBB6605	2.5	HBB7709	1.6
				JBB4422	4.2.2	HBB6606	2.6	HBB7720	1.7
				HBB4430	4.3.0	JBB6607	2.7	HBB7730	1.8
				HBB5510	5.1.0	HBB6608	2.8	HBB7740	1.9
				HBB5520	5.2.0	JBB6609	2.9	HBB7750	1.10
				JBB5522	5.2.2	HBB7703	2.10

CMD

The CMD parameter specifies the suffixes for the COMMNDxx.ini configuration files. Unlike the other configuration files, the COMMNDxx.ini files are read by the Tachyon Instruction Emulator’s debugger. The debugger reads these files just before it displays the first command prompt for each job step, allowing the debugger session to be customized. The CMD parameter value must be either a single value or a list of values surrounded by parentheses and separated by commas. Each value must be two characters and each character must each be either a digit (0-9) or an upper case letter (A-Z). If not specified, the default value is CMD=00, which will cause the debugger to read the COMMND00.ini configuration file. If more than one suffix is specified, each COMMNDxx.ini member will be read and processed.

DFP

The DFP parameter specifies the level of the Data Facilities Product to be set in various operating system control blocks. If not set, the default value is HDP1110. Changing the BCP level does not change the behavior of the Tachyon Operating System. The only effect of changing the DFP level is to set various flags which are often tested by applications to determine the available services. If the BCP parameter is set to HBB7703 (OS/390 2.10) or higher (e.g. z/OS), the DFP parameter is ignored and the flags are set to be appropriate to the SMS release corresponding to the BCP FMID. The accepted values are one of the following FMIDs:

DFP		DF/SMS
FMID	Release	FMID	Release
HDP1110	1.1.0	JDZ1110	1.1.0
HDP2210	2.1.0	HDZ11B0	1.2.0
HDP2230	2.3.0	JDZ11C0	1.3.0
HDP2232	2.3.2	HDZ11D0	1.4.0
HDP2240	2.4.0	HDZ11E0	1.5.0
HDP3310	3.1.0
JDP3311	3.1.1
HDP3320	3.2.0
JDP3321	3.2.1

DSNMAP

The DSNMAP parameter specifies the suffixes for the DSNMAPxx.ini configuration files. The DSNMAP parameter value must be either a single value or a list of values surrounded by parentheses and separated by commas. Each value must be two characters and each character must each be either a digit (0-9) or an upper case letter (A-Z). If not specified, the default value is DSNAMP=00, which will cause the Tachyon Operating System to read the DSNMAP00.ini configuration file. If more than one suffix is specified, each DSNMAPxx.ini member will be read and processed.

LNK

The LNK parameter specifies the suffixes for the LNKLSTxx.ini configuration files. The LNK parameter value must be either a single value or a list of values surrounded by parentheses and separated by commas. Each value must be two characters and each character must each be either a digit (0-9) or an upper case letter (A-Z). If not specified, the Tachyon Operating System will not read any LNKLSTxx.ini configuration files and the only data set in the Link Library concatenation will be SYS1.LINKLIB. If more than one suffix is specified, each LNKLSTxx.ini member will be read and processed.

LNKAUTH

The LNKAUTH parameter specifies whether the data sets in the Link List concatenation will be automatically APF authorized or if they will only be authorized if they are also in the APF table defined by the PROGxx.ini configuration files. The LNKAUTH parameter value must be either LNKLST or APFTAB. If the LNKAUTH parameter is not specified, the default value LNKLST will be used.

LPA

The LPA parameter specifies the suffixes for the LPALSTxx.ini configuration files. The LPA parameter value must be either a single value or a list of values surrounded by parentheses and separated by commas. Each value must be two characters and each character must each be either a digit (0-9) or an upper case letter (A-Z). If not specified, the Tachyon Operating System will not read any LPALSTxx.ini configuration files and the only data set in the LPA library concatenation will be SYS1.LPALIB. If more than one suffix is specified, each LPALSTxx.ini member will be read and processed.

OMVS

The OMVS parameter specifies the suffixes for the BPXPRMxx.ini configuration files. The OMVS parameter value must be either a single value or a list of values surrounded by parentheses and separated by commas. Each value must be two characters and each character must each be either a digit (0-9) or an upper case letter (A-Z). If not specified, the Tachyon Operating System will not read any BPXPRMxx.ini configuration files and the UNIX System Services will be unavailable. The OMVS parameter is ignored if the BCP parameter does not specify an OS/390 or z/OS release (HBB6601 or higher). If more than one suffix is specified, each BPXPRMxx.ini member will be read and processed.

PROG

The PROG parameter specifies the suffixes for the PROGxx.ini configuration files. The PROG parameter value must be either a single value or a list of values surrounded by parentheses and separated by commas. Each value must be two characters and each character must each be either a digit (0-9) or an upper case letter (A-Z). If not specified, the Tachyon Operating System will not read any PROGxx.ini configuration files and the only data set in the APF table will be SYS1.LINKLIB. If more than one suffix is specified, each PROGxx.ini member will be read and processed.

SVC

The SVC parameter specifies the suffixes for the IEASVCxx.ini configuration files. The SVC parameter value must be either a single value or a list of values surrounded by parentheses and separated by commas. Each value must be two characters and each character must each be either a digit (0-9) or an upper case letter (A-Z). If not specified, the Tachyon Operating System will not read any IEASVCxx.ini configuration files. If more than one suffix is specified, each IEASVCxx.ini member will be read and processed.

TRACE

The TRACE parameter specifies the size of the instruction trace buffer. One or two numeric values may be specified. If two values are specified they must be surrounded by parentheses. The first value is the initial size of the instruction trace buffer for programs being debugged. The second value is the initial size of the instruction trace buffer for programs not being debugged. If only one value is specified, it is used for both sizes. Each value can be from 0 to 999. The value of 0 disables instruction tracing initially. While debugging, the instruction tracing can be enabled or disabled, the size of the buffer can be altered and the buffer can be displayed by using the show itrace debugger command. If not specified, the default value is TRACE=(32,0).
