Backup and archive recommendations
| # | Item | How often to backup | Need to stop engine | Recommendations |
|---|---|---|---|---|
| 1 | FIXEdge binaries Default path in the package:
| Should be backuped before and after FIXEdge upgrade. | N | Optional. Can be download from the official site. To restore FIXEdge binaries, stop it and replace the files in the appropriate directories with the files from the backup |
| 2 | FIXEdge configuration Default path in the package:
| Should be backuped before and after modifications. For FIXEdge configuration - including changes done from FIXICC | N | It is responsible of FIXEdge user to track configuration changes. EPAM isn’t supposed to do it for the client. Daily configuration backup is the good practice in case of frequent changes. /etc/odbc.ini – could be considered as a part of FIXEdge configuration if FIXEdge uses DSN from there. Be careful, all data sources (not only for FIXEdge) are configured in /etc/odbc.ini file To restore FIXEdge configuration replace the files in the appropriate directories with the files from the backup. Settings will be applied after start/restart. |
| 3 | Operational scripts Default path in the package:
| N | ||
| 4 | FIXEdge application logs Default path in the package: <FIXEdge_Package>/FIXEdge1/log | Depends on maintenance window schedule defined by the user (daily or weekly). | Y | Keeping the recent logs are very useful for debugging and troubleshooting. It is possible to configure the rotation of the logs at which the old logs will be overwritten by fresh ones. Log rotation allows to limit space for application log. Otherwise, FIXEdge user should be aware of free disk space. Example: FIXEdge.properties Log.File.Rotate=true Log.File.Cycling=true # Maximum 100MB for FIXEdge log Log.File.Rotate.SizeLimit = 104857600 # 5 files total (i.e. 500MB) Log.File.Rotate.FileLimit = 5 Log.File.Name = FIXEdge1/log/FixEdge.log Log.File.Rotate.Dir = <path to archive storage>/log Archiving roteted logs FIXEdge.log.N not required stop the application |
| 5 | FIXICC Agent application logs Default path in the package:
| Depends on maintenance window schedule defined by the user (daily or weekly). | Y | Keeping the recent logs are very useful for debugging and troubleshooting. FIXICC used Log4j library. Archiving roteted logs fixicc-agent.log not required stop the application |
| 6 | Sessions logs | Depends on sessions schedule (daily or weekly). | N | Should be archived somewhere by default it is <FIXEdge_Package>/FIXEdge1/logs/archive. Archiving is done automatically for session on TerminateTime. TerminateTime should be 1-2 minutes earlier than FIXEdge shutdown to ensure that all logs moved correctly. For session logs storage speed is important, so quick storage should be used. Archived Logs could be moved to slower storage Example: Make sure that session log enabled: engine.properties LogIncomingMessages = true LogDirectory = FIXEdge1/log To configure
FIXEdge.properties FixLayer.FixEngine.Sessions.ArchivePath = <path to archive storage>/log #Session Schedule configuration: Monday-Friday, 07:00 - 23:00. End of day 23:10 Schedules.ClientSchedule1.StartTime = 0 0 7 * * 2-6 Schedules.ClientSchedule1.TerminateTime = 0 0 23 * * 6 # ... FixLayer.FixEngine.Session.Session1.Schedule = ClientSchedule1 FixLayer.FixEngine.Session.Session1.StorageType = persistentMM Such configuration allows run FIXEdge with minimum space requirements. |
| 7 | File Histories | As histories are changed during a day it is better to archive it daily | Y | Example: BL_Config.xml ... <History Name="SessionData" StorageType="File" WorkingDirectory="FIXEdge1/log/" StorageFileName="SessionData"> <KeyFields>49, 56</KeyFields> <Fields>553</Fields> </History> ... For the history "SessionDate" be sure to configure backup files
for example, using the cron. |
| 8 | ODBC Histories | As histories are changed during a day it is better to archive it daily | - | Should be done by 3rd party tools, EPAM is not responsible for DB backup. |
