Determining when to change virtual terminal pool definitions

The default definition might need to be changed because of any of the following conditions:

• The size of the virtual terminal pool does not meet your needs.
• The names of the virtual terminals do not meet your site’s naming conventions.
• The VTAM LOGMODE name defaults are not appropriate.

Before you make any changes to the number of virtual terminals in the pool, consider the needs of all OMEGAMON for CICS (3270) users running the same copy of the KOBVTPL load module. Because virtual terminal pool definitions can be shared by multiple VTAM hosts, consider the maximum expected number of concurrent TSO and ISPF sessions as you determine the size of the virtual terminal pool.
