| ES_CLASS_XFCT | Overrides the default CICS FCT resource class. | CICS |
| ES_CLASS_XJCT | Overrides the default CICS JCT resource class. | CICS |
| ES_CLASS_XPCT | Overrides the default CICS PCT resource class. | CICS |
| ES_CLASS_XPPT | Overrides the default CICS PPT resource class. | CICS |

| ES_ESM_CMDSEC | Indicates whether CICS processing honors the CMDSEC option specified on a transaction's PLT definition. | CICS |
| ES_ESM_PLTPIUSR | The user id under which PLT programs run during CICS initialization. | CICS |
| ES_ESM_RESSEC | Indicates whether CICS processing honors the RLS security setting specified on a transaction definition (PCT). | CICS |
| ES_ESM_SECPRFX | Indicates whether CICS processing prefixes the resource names when making security queries.
Note: The environment variable ES_ESM_SECPRFX is only applied to CICS classes.
|
CICS |
| ES_ESM_XUSER | Indicates whether CICS processing performs surrogate user checks. | CICS |
| ES_PAC_NO_GLOBAL_LOG | Stops the messages in the console.log from being stored in the PSOR. | PAC |
| ES_SOR_RETRIES | Sets the number of attempts to access records in the PSOR before stopping. | PAC |
| ES_USR_DFLT_CICS | Enables you to override the default user when no user is logged on for CICS authentication. | CICS |
| ES_USR_DFLT_JCL | Enables you to override the default user when no user is logged on for JCL authentication. | JCL |
| ES_USR_DFLT_JES | Enables you to override the default user when no user is logged on for JES authentication. | JCL |

| ES_XA_RECONNECT | Set this to any value to configure the XA reconnect process to operate in a single attempt mode. | |
| ES_XA_%xaname%_OPTIONS | Set this environment variable for each RM that you require to operate in a multiple attempt mode. Replace the %xaname% component of the variable name with the name of the RM as specified in MFDS or
ESCWA . Specify the number of reconnect attempts to the target RM (up to a maximum of 9999) as well as the duration of the delay,
in seconds, between each attempt. If you set the variable to EX it will exclude the target RM from XA reconnect processing.
Dependency: Must be set along with ES_XA_RECONNECT=Y.
|
CICS |
| ES_xxxxx_NB_RETRIES | Specifies the number of times a SEP attempts to reconnect to an XA resource following a connection error, where xxxxx is the ID of the associated resource. The default is 5. If no connection is made, the XA switch is disabled. | CICS |
| MFSYSCAT | The location of the JES system catalog. | JCL |
| MFUSERCAT_BASE_LOC | If an entry in MFUSERCAT_LOC only specifies the file name of a user catalog rather than the full path and file name, use this environment variable to specify where these catalogs are located | JCL |
| MFUSERCAT_LOC | The location of the node(s) set in MFUSERCAT_NODE, separated by semi-colons if more than one is specified. | JCL |
| MFUSERCAT_NODE | Sets additional SMS, SPOOL and User catalogs. To enable support for the SMS entities DATACLAS and MGMTCLAS, this variable needs to be set in addition to setting MF_SMS=ON. | JCL |
