Executing for the first time an User-defined command either under Sysview ISPF or VTAM interface the following error is issued:
GSV2094E* parameter too long, max length is 32.
Then, if the same command is issued again, it works fine.
The description of the User-defined command is too long.
Execute Sysview command LISTLOG just after receiving the error GSVX320E, so additional information can be collected about the error.
In this case, the following message was returned :
GSVX320E*Invalid USERCMDS table entry. DESC ''WALLTRAN CICS Transaction Display'
So, the command description (DESC) is longer than 32 characters and reducing its length to under 32 characters long, resolves the problem.
