The first five fields in this data structure are identical to those in the previous level. See Server Level 1 for the type of software the computer is running.
sv2_ulist_mtime indicates the last time (in seconds from 00:00:00, 1 January 1970) the users list was changed.
sv2_glist_mtime indicates the last time (in seconds from 00:00:00, 1 January 1970) the groups list was changed.
sv2_alist_mtime indicates the last time (in seconds from 00:00:00 1 January 1970) the access control list was changed.
sv2_users indicates the number of users that are allowed on the server.
sv2_disc indicates the autodisconnect time (in minutes). A session is disconnected if it is idle longer than the time specified by sv2_disc. If sv2_disc is SV_NODISC, autodisconnect is not enabled.
sv2_alerts points to an ASCIIZ string containing the list of user names on the alert table of the server. Spaces separate the names.
sv2_security specifies the security type of the server. It is set to SV_USERSECURITY, which is defined as follows in SERVER.H: ﾚﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄｿ

sv2_auditing indicates whether auditing is enabled on the server. If 0, auditing is disabled. If not 0, the server audits LAN Server activities, as described in Auditing Category.
sv2_numadmin indicates the number of administrators a server can accommodate at the same time.
sv2_lanmask determines the order in which the network device drivers are served.
sv2_hidden determines whether the server is visible to other computers in the same domain. sv2_hidden is defined as follows in SERVER.H: ﾚﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾂﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄｿ

sv2_announce specifies the network announce delta (in seconds), which determines how often the server is to be announced to other computers on the network.
sv2_anndelta specifies the random announce rate (in milliseconds) for sv2_announce. The announce interval (sv2_announce) can vary by the amount specified in sv2_anndelta For example, it could vary from 9.999 seconds to 10.001 seconds, instead of being exactly 10 seconds each time.
sv2_guestacct is an ASCIIZ string containing the name of a server reserved GUEST user account.
sv2_pad1 word-aligns the data structure components.
sv2_userpath points to an ASCIIZ string containing the path name to user directories.
sv2_chdevs indicates the number of serial devices that can be shared on the server.
sv2_chdevq indicates the number of serial device queues that can coexist on the server.
sv2_chdevjobs indicates the number of serial device jobs that can be pending on a server.
sv2_connections indicates the number of connections to netnames that are allowed on a server.
sv2_shares indicates the number of netnames a server can accommodate.
sv2_openfiles indicates the number of files that can be opened at once.
sv2_sessopens indicates the number of files that can be opened in one session.
sv2_sessvcs indicates the maximum number of virtual circuits per client.
sv2_sessreqs indicates the number of simultaneous requests a client can make on any virtual circuit.
sv2_opensearch indicates the number of searches that can be opened at once.
sv2_activelocks indicates the number of file locks that can be active.
sv2_numreqbuf indicates the number of server buffers that are provided.
sv2_sizreqbuf indicates the size (in bytes) of each server buffer.
sv2_numbigbuf indicates the number of 64KB server buffers that are provided.
sv2_numfiletasks indicates the number of processes that can access the operating system at one time.
sv2_alertsched indicates the alert interval (in seconds) for notifying an administrator of a network event.
sv2_erroralert indicates the number of entries that can be written to the error log file during a sv2_alertsched interval before notifying an administrator.
sv2_logonalert indicates the number of failed logon attempts to allow a user before notifying an administrator.
sv2_accessalert indicates the number of failed file accesses to allow before issuing an administrative alert.
sv2_diskalert indicates the number of kilobytes of free disk space at which an administrator must be notified that the free space is low.
sv2_netioalert indicates the network I/O error ratio (in tenths of a percent) to allow before notifying an administrator.
sv2_maxauditsz indicates the maximum audit file size (in KB).
sv2_srvheuristics points to an ASCIIZ string of flags used to control the operations of a server.
The heuristics default to values that are optimal for most configurations and normally need not be changed.

For the defaults and ranges of the previous fields, see the IBMLAN.INI parameter descriptions in the LAN Server Network Administrator Reference Volume 2: Performance Tuning.
