Guide d'exploitation ONYX Server sur Linux/en

<languages/>
=== Introduction ===

This article provides you with examples of operations on ONYX Server under Linux. This needs to be adapted according to your internal processes. 

This only regards ONYX Server. The administration of Apache web server (stop / restart) is not described in this article.

=== General operations ===
==== Selecting the Mapping instance ====
Several different ONYX Server instances can be installed on the same Unix/Linux server. This way, specifying the Mapping environment is required before entering any command. This is done by changing the MAPPING_PATH environment variable.

In interactive mode: with the "mappingenv" command
 -bash-4.2$ mappingenv
 Which environment must be changed:
 1 : Mapping_PROD   /apps/mapping/conf/mapping.conf 8002
 Enter the name or number of the environment:1
 bash-4.2$

The list of environments is is based on the /etc/mappingtab file

The mappingenv command is located in " /bin " by default
                
In a script: The MAPPING_PATH environment variable must be exported with the complete path of the mapping.conf file which corresponds to the desired Mapping environment.

 export MAPPING_PATH=/apps/mapping/conf/mapping.conf

=== Log files ===
==== General information on log files ====
Most Mapping log files are not in text format, they thus cannot be edited as is.
There are two methods used to see them:
* Via the Mapping Web interface
* Using the /apps/mapping/bin/map_log_txt command


For more information on this command: 
 /apps/mapping/bin/map_log_txt --help

Display example of the content of the log file of the map_lpd:
 /apps/mapping/bin/map_log_txt -log_file:/apps/mapping/spool/logs/map_lpd.log

==== Common log files ====
Most log files are located in the /apps/mapping/spool/logs folder.

Log file examples:

{| class="wikitable"
|-
| <name of the queue>.log || Logs linked to queues (printer or entry points)
|-
| map_daemon.log || General log of the spooler
|-
| map_lpd.log || Log of the LPD server
|-
| map_lpr.log || Log of the LPR Mapping client if called in a command line
|}

To access it via the interface: "Main menu" / "View log"

==== Log files linked to standard outputs and errors ====
 /apps/mapping/temp/stdout.txt
 /apps/mapping/temp/stderr.txt

These are text files which can be edited as is without needing to be converted.

==== Log files of the jobs in the spooler ====
Each job has its own log file. These files are located in the /apps/mapping/spool/global file. Their name starts with the letter L followed by the number of the job (MAP_JOBNUM).
 
=== Processes ===
==== Description of the main Mapping processes ====
The following processes are frequently seen when displaying the list of current processes. This is often done using the following command: 
 ps -eaf | grep map

{| class="wikitable"
|-
| map_daemon || Processes of the spooler which allow jobs to be managed in the queues.
|-
| map_lpd || Recovery process of the jobs sent via LPR. This is a child of the map_daemon process.
|-
| map_splf || Process which notably allows you to add a job in a queue. This is a child of the map_lpd process, it communicates with the map_daemon process via the port defined by the PORT_SOCKET_DAEMON parameter in the mapping.conf file. It can also be directly triggered in command line to manage queues or jobs.
|-
| map_exec || Process which handles jobs in queues to apply processes to them (workflow, script execution, delivery to a printer…). This is a child of the  map_daemon process. There is one map_exec per queue being processed.
|-
| map_lpr || Process which sends a printing stream to a printer using the LPR protocol. This is a child of the map_exec process. It can also be directly triggered in command line.
|-
| map_809 || Execution Process of a Workflow. This is a child of the  map_exec process.
|-
| mapcpysplf || Process which calls for the mapping of a document. It can be triggered in command line, in a script, in the workflow (map_809)…
|-
| map_815UCS || Mapping processus of a document (called by the mapcpysplf command).
|-
| map_mail || Process which sends an e-mail with an attachment.
|-
| map_scanfolder || Process linked to a robot which allows you to monitor files in a folder so as to launch a workflow processing on each of them.
|}

Other processes with the prefix " map_ " can also be seen, notably if they are called via scripts or in the workflow.

==== Starting and stopping Mapping processes ====

=====<u> Starting the spooler</u> =====

The following command launches the map_daemon process as well as its child map_lpd
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf 
 /apps/mapping/bin/map_daemon start

When starting the map_daemon process, a flag file which contains the process identifier of map_daemon process is created in the spooled file folder. The process cannot start because of it.
 /apps/mapping/spool/map_daemon.ID

=====<u> Stopping the spooler</u> =====

The following command stops the map_daemon process as well as its child map_lpd
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf
 /apps/mapping/bin/map_daemon stop

Caution: if "scanfolder" robots processing consists in sending a file to a queue of the spooler, stopping the map_daemon process will result in errors each time a file is processed. It is therefore essential to stop the "scanfolder" robots before stopping the map_daemon process.

=====<u> Starting the "scanfolder" robots </u> =====

The following command starts a "scanfolder" robot
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf
 /apps/mapping/bin/map_scanfolder -name:nom_du_robot

Example of a script to start all the robots:
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf
 LISTROBOT=`/apps/mapping/bin/map_scanfolder -listRobot | awk ' { print $2 } '`
 for ROBOT in $LISTROBOT
 do
 /apps/mapping/bin/map_scanfolder -name:${ROBOT}
 done

When starting the map_scanfolder process, a flag file which contains the process identifier of the map_scanfolder process is created in the temp folder. The process cannot start because of it. It needs to be deleted.
 /apps/mapping/temp/_apps_mapping_temp_nom_du_robot_map_scanfolder.ID

Caution: deleting this .ID file should only be done if the robot is not being run. When deleting this file, launching another instance of the same robot is possible which causes concurrency conflicts.

=====<u> Stopping the "scanfolder" robots </u> =====

The following command stops a "scanfolder" robot
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf
 /apps/mapping/bin/map_scanfolder -stop -name:nom_du_robot

Example of a script to stop all the robots:
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf
 LISTROBOT=`/apps/mapping/bin/map_scanfolder -listRobot | awk ' { print $2 } '`
 for ROBOT in $LISTROBOT
 do
 /apps/mapping/bin/map_scanfolder -stop -name:${ROBOT}
 done

==== Processes to monitor ====
=====<u> map_daemon and map_lpd</u> =====
These 2 processes are services and need to be run incessantly. Because they are often forked, there may be several of these processes at some point.
 -bash-4.1$ ps -eaf | grep map_
 mapadmin 29551     1  1 Oct25 ?   04:00:29 /apps/mapping/bin/map_daemon start
 mapadmin 27424 29551  0 Oct30 ?   00:00:00 /apps/mapping/bin/map_lpd -port:515 -nbfork:100

=====<u> map_scanfolder</u> =====
There are as many map_scanfolder processes as there are robots being executed. They can be identified with the "-name" option. These processes do not depend on one another, neither do they depend on the map_daemon process. 
 mapadmin   8271  1  0 17:02 ? 00:00:00 /apps/mapping/bin/map_scanfolder -name:test

=====<u> httpd </u> =====
To check that Apache runs smoothly, use the httpd process. Because this process is often forked, several lines can be seen in the list of processes.
 -bash-4.2$ ps -eaf | grep httpd
 apache    4590 11849  0 10:56 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
 apache    4874 11849  0 08:23 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
 apache    4876 11849  0 08:23 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
 apache    4890 11849  0 08:23 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
 root     11849     1  0 oct.15 ?       00:01:42 /usr/sbin/httpd -DFOREGROUND
 apache   15641 11849  0 08:54 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND
 apache   16301 11849  0 08:56 ?        00:00:00 /usr/sbin/httpd -DFOREGROUND

==== In case a Mapping process crashes ====
=====<u> map_daemon crashed </u> ===== 
1-	Try stopping the Mapping spooler properly:
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf
 /apps/mapping/bin/map_daemon stop

2-	Stop the active scanfolder processes properly (see starting and stopping Mapping processes)

3-	Kill (kill -9) the other mapping processes which are still active:
* map_daemon
* map_lpd
* map_exec
* map_lpr
* map_809

It is worth noting that processes can become children of the system process (PID=1) in case the process they originate from crashes, common characteristic: they are owned by "mapadmin".

Example (adapt this depending on your system and its configuration):
 ps -f -U mapadmin | grep -v bash | grep -v "ps \-f" | grep -v "UID" | while read LINE
 do
  PID=`echo $LINE | awk ' { print $2 } '`
  kill -9 $PID
 done

4-	Delete the flag file /apps/mapping/spool/map_daemon.ID

5-	Start the Mapping spooler
 /apps/mapping/bin/map_daemon start

=====<u> map_lpd crashed </u> =====
If the map_daemon process is still active, sretarting the map_lpd can be done using the following command:
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf
 /apps/mapping/bin/map_control -start_lpd

=====<u> a "scanfolder" robot crashed </u>=====
When starting a robot, a file with the same name as the robot and a ".ID" extension is created, as well as a file with the process number and and a .pid extension
Example: 
 _apps_mapping_temp_nom_du_robot_map_scanfolder.ID
 4656.pid

Were the robot to crash, these files would not be deleted and would prevent the robot from being restarted.
To restart the robot, the ".ID" file which corresponds to the crashed robot must then be deleted from the " /apps/mapping/temp " folder

=== Maintenance ===
==== Regular cleanings ====
The following commands can be set to be executed regularly. Ideally, at least once a day. 
=====<u> Deleting finished and expired jobs</u> =====
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf 
 /apps/mapping/bin/map_cron -date

=====<u> Deleting non finished jobs (no matter their status), after 30 days</u> =====
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf 
 /apps/mapping/bin/map_cron -cleanspool -relative_date:30/0/0.  # jour/mois/années

=====<u> Deleting outdated web session files </u> =====
context_menu.*, history.*, and *.id files in the /apps/mapping/temp folder
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf 
 /apps/mapping/bin/map_cron -cleanid

=====<u> Deleting XPS conversion and Workflow temporary files </u> =====
These files are located in the /apps/mapping/temp temporary folder.
They are normally deleted automatically. In case of problem (crash, forced interruption…), they may remain in the temporary file.
It is then not a normal situation.
 find /apps/mapping/temp -name "*cri.tmp"     -mtime +2 -exec rm -f {} \;
 find /apps/mapping/temp -name "*ttf.tmp"     -mtime +2 -exec rm -f {} \;
 find /apps/mapping/temp -name "compress_*"   -mtime +2 -exec rm -f {} \;
 find /apps/mapping/temp -name "*.[0-9]"      -mtime +2 -exec rm -f {} \;
 find /apps/mapping/temp -name "*.[0-9][0-9]" -mtime +2 -exec rm -f {} \;

==== Cleaning and log rotation ====
For practical reasons, the following commands must not scheduled for more than once a day. The aim is to prevent increasing the number of archives created, thus preventing the loss of the logs of the last days. The ideal frequency is 2 times a week, for instance monday night and thursday night, before the night batches are trigerred.
=====<u> Archiving logs</u> =====
This command allows you to convert any log file to text format and afterwards, to archive it in a zipped file which shows the date and time.
 export MAPPING_PATH=/apps/mapping/conf/mapping.conf 
 /apps/mapping/bin/map_cron -cleanlog -folder:/apps/mapping/spool/logs -format:TXT

Result:
 bash-4.2$ ls -lrt /apps/mapping/spool/logs/*.zip
 -rw-r--r-- 1 mapadmin staff 254186924 30 oct.  /apps/mapping/spool/logs/2018_10_30_19_51.zip
 -rw-r--r-- 1 mapadmin staff  58479965  7 nov.  /apps/mapping/spool/logs/2018_11_07_12_32.zip

=====<u> Log rotation of the standard outputs and errors </u> =====
 mv  /apps/mapping/temp/stderr.txt  /apps/mapping/temp/stderr.txt.bak 
 mv  /apps/mapping/temp/stdout.txt  /apps/mapping/temp/stdout.txt.bak

=====<u> Deleting log archives that are older than 30 jours</u> =====
 find /apps/mapping/spool/logs -name "*.zip" -mtime +30 -exec rm -f {} \;

=====<u>Archiving logs</u>=====
This command allows you to convert any log file to text format and afterwards, to archive it in a zipped file which shows the date and time.
export MAPPING_PATH=/apps/mapping/conf/mapping.conf 
 /apps/mapping/bin/map_cron -cleanlog -folder:/apps/mapping/spool/logs -format:TXT

Result:
