Startup Parameters

Default command line arma2oaserver.exe -port=2302 -config=server.cfg -cfg=basic.cfg -profiles=profiles -name=server -world=empty -mod="@DayZ;@DayZ_Epoch" -serverMod="@DayZ_Server;@hive" -cpuCount=4 -exThreads=7 -nosplash -noPause -noSound -malloc=system -hugepages

Parameters

• -port=<P> — Game UDP port. Default 2302.
• -config=server.cfg — gameplay, passwords, mission rotation.
• -cfg=basic.cfg — networking (MaxMsgSend, packet sizes), timestamps.
• -profiles=<dir> — logs (.RPT), netlogs, dumps.
• -name=<profile> — creates <profile>.ArmA2OAProfile (difficulty, view distance).
• -mod= — client+server mods; load order matters.
• -serverMod= — server-only mods (Hive/antihack).
• -cpuCount, -exThreads, -malloc, -hugepages, -world=empty, -noPause, -noSound, -nosplash, -logFile, -pid, -ranking.
• -BEpath=<dir> — BattlEye directory.

Ports

• Game: P UDP (default 2302)
• Query: P+1 UDP
• Steam master: 27016 UDP
• BattlEye: 2344–2345 UDP, RCon TCP as per BEServer.cfg

Config Files & Locations

• Root:
  • server.cfg — hostname, verifySignatures, vote rules, MOTD, missions.
  • basic.cfg — bandwidth & network tuning.
• Profiles (-profiles):
  • <name>.ArmA2OAProfile — difficulty profile.
  • *.RPT — main runtime log.
• BattlEye (Expansion/BattlEye or -BEpath):
  • BEServer.cfg — RConPassword, RConPort.
  • scripts.txt, remoteexec.txt — filter lists.
• Keys: keys/*.bikey (required when verifySignatures=2).
• DayZ/Epoch server component:
  • @DayZ_Server / @hive with HiveExt.dll.
  • Mission PBO: MPMissions/DayZ_Epoch_11.Chernarus.pbo (example).

Steam Workshop

Not natively used for Arma 2 OA; install @Mod folders manually and copy .bikey to keys/.

Common Mods

• DayZ Epoch
  • Install: place @DayZ_Epoch and @DayZ_Server in root; add to -mod and -serverMod.
  • Configure: @DayZ_Server\config.cfg and HiveExt.ini (DB). Ensure server and client versions match.
• Overwatch / Overpoch
  • Install @DayZOverwatch, adjust mission PBO to Overpoch variant.
  • Merge/add .bikey keys.
• Anti-hack/admin (e.g., infiSTAR)
  • Server-side only in -serverMod; follow vendor config.

Database

• MySQL (port 3306). Connection is in HiveExt.ini:
  • Host = <ip_or_dns>
  • Database = dayz
  • Username = dayzuser
  • Password = ********
  • Instance = 11 (matches mission instance)
• Create schema using mod-provided SQL. Index cleanup & periodic maintenance recommended.

Administration & Scripting

Remote Administration:

• BattlEye RCON for server management and player control
• In-game admin tools via infiSTAR or similar anti-hack solutions
• Database admin tools for character/vehicle management

Backup Strategy:

• Automated daily backups of MySQL database (character data, vehicles, bases)
• Configuration file backups (server.cfg, basic.cfg, mission files)
• Rotate backups (keep 7 daily, 4 weekly, 12 monthly)
• Test database restore procedures regularly

Auto-Update:

• Monitor mod releases for client/server version synchronization
• Schedule updates during low-traffic periods
• Backup database and configs before applying updates
• Test mod compatibility before deploying to production

Monitoring:

• Database performance monitoring (connection counts, query performance)
• Server performance via .RPT logs and BattlEye reports
• Player statistics and anti-cheat logging
• Uptime and restart scheduling for stability

Troubleshooting

• HiveExt.dll fails / DB won’t connect: wrong creds or MySQL not reachable; VC++ redists missing.
• “Waiting for host” loop: wrong Instance vs DB content; mission PBO mismatch; see .RPT.
• Script restriction kicks: update/merge BE filters with mod’s recommended entries.
• Signature mismatch: missing .bikey for a loaded mod; ensure keys/ contains all and clients use same versions.
• Severe desync: tune basic.cfg bandwidth settings; reduce AI/vehicles; lower player cap.
