getManagerLevel(int manager)
get the Application requester manager level |

setManagerLevel(int manager,
int managerLevel)
set Application requester manager level if the manager level is less than the minimum manager level, set the manager level to zero (saying we can't handle this level), this will be returned to the application requester and he can decide whether or not to proceed For CCSIDMGR, if the target server supports the CCSID manager but not the CCSID requested, the value returned is FFFF For now, we won't support the CCSIDMGR since JCC doesn't request it. |

supportedMessageParamLength()
Get the maximum length supported for an exception's message parameter string. |
