Defining Logon Mode Table Entries

The Logon Mode table defined by the MODETAB parameter contains the session parameters required by the workstations. Define the transfer session for the LU6.2 communication for your DC system.

Logon Mode table entries for CICS

To connect a workstation to CICS, define a Logon Mode in your VTAM Logon Mode table. Use the following example:

<LU62SAP1> MODEENT LOGMODE=<LU62SAP1>,
Type=00
FMPROF=X'13',
TSPROF=X'07',
PRIPROT=X'B0',
SECPROT=X'B0',
COMPROT=X'50B1',
SSNDPAC='3F'
PRCVPAC='3F'
SRCVPAC='3F'
RUSIZES=X'8787',
PSERVIC=X'060200000000000000002C00'

The SAP example value for the LOGMODE parameter is LU62SAP1. If you are using another value, it has to match the value of the VTAM parameter MODETAB.

The parameter entry for RUSIZES must match the parameter entry for SENDSIZE defined in CICS.

In this LOGMODE we recommend that, for optimum performance, you set the parameters as follows for both directions:
Block size: 1024 (X ' 8787: 87: 8*2 7 = 1024, therefore 8787 for both directions)
Pacing values:
63 (hex: 3F)

Logon Mode Table entries for IMS

To connect a workstation to IMS, you must make two Logon Mode definitions for the following sessions:

Define a Logon Mode in your VTAM Logmode Table. Use the following example:

* for LU 6.1 adapter *
LU6NEGS MODEENT LOGMODE=LU6NEGS,
FMPROF=X'12',TSPROF=X'04',TYPE=X'00',
PRIPROT=X'B1',SECPROT=X'B1',COMPROT=X'70A0',
RUSIZES=X'F8F8',PSERVIC=X'060038000000380000000000'
* for IMS itself *
LU62SAP1 MODEENT LOGMODE=LU62SAP1,
FMPROF=X'13',TSPROF=X'07',TYPE=X'00',
PRIPROT=X'B0',SECPROT=X'B0',COMPROT=X'50B5',
SSNDPAC=‘3F’, PRCVPAC=‘3F’,SRCVPAC=‘3F’
RUSIZES=X'8787,PSERVIC=X'060200000000000000002F00'

In this LOGMODE we recommend that, for optimum performance, you set the parameters as follows for both directions:
Block size: 1024 (X
' 8787: 87: 8*2 7 = 1024, therefore 8787 for both directions)
Pacing values: 63 (hex: 3F)
