1) At one time the max sessions was 32, but the max must be specified at sysgen, I beleive. This may have been increased in later releases. The default is 8.
2) You can define a cursor, then the # of rows returned is, I hesitate to say limitless, but it can attain dataset proportions. |

Hi,
Maximum we can open 8 screens on Mainframes. In our mainframes TSOPlus tool is uploaded, with that we can open 12 screens, but it can be counted as only one screen as TSOP.
Regards,
Mike. |

The max screens you can use is selected by the systems pgmr that genned your system. He must have selected the default (which is 8).
Can't comment on TSOPlus - never used it. |

Listen up folks!
You can open up to 32 screens in TSO (that limit may have been increased) **IF** your sysprmr picked 32 as the default for YOUR installation.
If he doesn't select a number the installation gets the IBM default of 8. |

You need to define what you mean by 'session'. If you mean VTAM or TCP/IP sessions, then if you have the proper tools, you can be logged on to TSO/E, IMS, CICS, etc., all at the same time. Each is a 'session' as far as VTAM or TCP/IP is concerned.
If you mean TSO, then it's one TSO userid per TSO session. If you have more than one unique userid assigned to you, each one can be logged at the same time as all the others. Usually, applications programmers only get one TSO userid each.
If you mean ISPF screen splits, then 32 is the max per TSO logon session. These are NOT all 'sessions', just separate subtasks to ISPF within the TSO address space.
TSOPlus is an ISV (i..e,non-IBM) product that changes the way TSO resources are managed. Logon rules for it may vary from those stated above. |
