Configuration properties glossary

Introduction

The primary form of configuration is via the use of key/value properties, stored in etc/grid/config.xml and read on server startup. Backing up and copying these properties is as easy as copying this file to a new server version.

The https://github.com/ome/openmicroscopy/blob/develop/etc/omero.properties file of your distribution defines all the default configuration properties used by the server. Changes made to the file are not recognized by the server. Instead, configuration options can be set using the omero config set command:

$ omero config set <parameter> <value>

When supplying a value with spaces or multiple elements, use single quotes. The quotes will not be saved as part of the value (see below).

To remove a configuration option (to return to default values where mentioned), simply omit the value:

$ omero config set <parameter>

These options will be stored in a file: etc/grid/config.xml which you can read for reference. DO NOT edit this file directly.

You can also review all your settings by using:

$ omero config get

which should return values without quotation marks.

A final useful option of omero config edit is:

$ omero config edit

which will allow for editing the configuration in a system-default text editor.

Note

Please use the escape sequence \" for nesting double quotes (e.g. "[\"foo\", \"bar\"]") or wrap with ' (e.g. '["foo", "bar"]').

Examples of doing this are on the server installation page, as well as the LDAP installation page.

Mandatory properties

The following properties need to be correctly set for all installations of the OMERO.server. Depending on your set-up, default values may be sufficient.

  • omero.data.dir

  • omero.db.host

  • omero.db.name

  • omero.db.pass

Binary repository

property omero.checksum.supported

omero.checksum.supported

Checksum algorithms supported by the server for new file uploads, being any comma-separated non-empty subset of:

  • Adler-32

  • CRC-32

  • MD5-128

  • Murmur3-32

  • Murmur3-128

  • SHA1-160

  • File-Size-64

In negotiation with clients, this list is interpreted as being in descending order of preference.

Default: SHA1-160, MD5-128, Murmur3-128, Murmur3-32, CRC-32, Adler-32, File-Size-64

property omero.data.dir

omero.data.dir

Default: /OMERO/

property omero.fs.repo.path

omero.fs.repo.path

Value dynamically set during the build Template for FS managed repository paths. Allowable elements are:

%user%         bob
%userId%       4
%group%        bobLab
%groupId%      3
%year%         2011
%month%        01
%monthname%    January
%day%          01
%time%         15-13-54.014
%institution%  University of Dundee
%hash%         0D2D8DB7
%increment%    14
%subdirs%      023/613
%session%      c3fdd5d8-831a-40ff-80f2-0ba5baef448a
%sessionId%    592
%perms%        rw----
%thread%       Blitz-0-Ice.ThreadPool.Server-3
/              path separator
//             end of root-owned directories

These are described further at FS configuration options

The path must be unique per fileset to prevent upload conflicts, which is why %time% includes milliseconds.

A // may be used as a path separator: the directories preceding it are created with root ownership, the remainder are the user’s. At least one user-owned directory must be included in the path.

The template path is created below omero.managed.dir, e.g. /OMERO/ManagedRepository/$omero.fs.repo.path/

Default: %user%_%userId%//%year%-%month%/%day%/%time%

property omero.fs.repo.path_rules

omero.fs.repo.path_rules

Rules to apply to judge the acceptability of FS paths for writing into omero.managed.dir, being any comma-separated non-empty subset of:

  • Windows required

  • Windows optional

  • UNIX required

  • UNIX optional

  • local required

  • local optional

Minimally, the “required” appropriate for the server is recommended. Also applying “optional” rules may make sysadmin tasks easier, but may be more burdensome for users who name their files oddly. “local” means “Windows” or “UNIX” depending on the local platform, the latter being applied for Linux and Mac OS X.

Default: Windows required, UNIX required

omero.client.icetransports

Comma separated list of Ice transports available to clients. The default value (“ssl,tcp”) instructs Ice to open the ports specified by the omero.ports.ssl and omero.ports.tcp properties. Restricting to “ssl” will prevent all non-encrypted connections to the OMERO server.

Additionally, there are two experimental values for using websockets: “ws” and “wss” for unencrypted and encrypted, respectively. The ports that are opened are controlled by the omero.ports.ws and omero.ports.wss properties. To enable all possible protocols use: “ssl,tcp,wss,ws”.

Note: When using websockets behind a web server like nginx, additional configuration may be needed.

Default: ssl, tcp

property omero.db.poolsize

omero.db.poolsize

Sets the number of database server connections which will be used by OMERO.

A sizeable increase in this value, e.g. to 100, will significantly increase the performance of your server, but your database installation will need to be configured to accept at least as many, preferably more, connections as this value.

The related values omero.threads.max_threads and omero.threads.background_threads do not need to be increased by the same amount. A system will be more stable if background_threads is less than max_threads and max_threads is less than poolsize.

Contains other parameters which should be passed to the JVM. The value of “append” is treated as if it were on the command line so will be separated on whitespace. For example, ‘-XX:-PrintGC -XX:+UseCompressedOops’ would results in two new arguments. Note that when using config set from the command line one may need to give a prior option to prevent a value starting with - from already being parsed as an option, and values may need quoting to prevent whitespace or other significant characters from being interpreted prematurely.

Enable or disable LDAP (true or false).

Default: false

property omero.ldap.connect_timeout

omero.ldap.connect_timeout

Sets com.sun.jndi.ldap.connect.timeout on the Spring LDAP default security context source environment. The context source is responsible for interacting with JNDI/LDAP.

This timeout is specified in milliseconds and controls the amount of time JNDI/LDAP will wait for a connection to be established.

A timeout less than or equal to zero means that no timeout will be observed and that the OMERO server will wait indefinitely for LDAP connections to be established. Such a timeout should be used with extreme caution as connectivity issues may then cause your server to no longer be able to create new sessions.

For more information on what this JNDI/LDAP property does, see https://docs.oracle.com/javase/jndi/tutorial/ldap/connect/create.html

Default: 5000

property omero.ldap.group_filter

Default: (objectClass=groupOfNames)

property omero.ldap.group_mapping

omero.ldap.group_mapping

Default: name=cn

property omero.ldap.new_user_group

omero.ldap.new_user_group

Without a prefix the “new_user_group” property specifies the name of a single group which all new users will be added to. Other new_user_group strings are prefixed with :x: and specify various lookups which should take place to find one or more target groups for the new user.

:ou: uses the final organizational unit of a user’s dn as the single OMERO group e.g. omero.ldap.new_user_group=:ou:

:attribute: uses all the values of the specified attribute as the name of multiple OMERO groups. e.g. omero.ldap.new_user_group=:attribute:memberOf

Like :attribute:, :filtered_attribute: uses all the values of the specified attribute as the name of multiple OMERO groups but the attribute must pass the same filter as :query: does. e.g. omero.ldap.new_user_group=:filtered_attribute:memberOf

Similar to :attribute:, :dn_attribute: uses all the values of the specified attribute as the DN of multiple OMERO groups. e.g. omero.ldap.new_user_group=:dn_attribute:memberOf

A combination of filtered_attribute and dn_attribute, :filtered_dn_attribute: uses all of the values of the specified attribute as the DN of multiple OMERO groups but the attribute must pass the same filter as :query: e.g. omero.ldap.new_user_group=:filtered_dn_attribute:memberOf

:query: performs a query for groups. The “name” property will be taken as defined by omero.ldap.group_mapping and the resulting filter will be AND’ed with the value group_filter (above) e.g. omero.ldap.new_user_group=:query:(member=@{dn})

:bean: looks in the server’s context for a bean with the given name which implements ome.security.auth.NewUserGroupBean e.g. omero.ldap.new_user_group=:bean:myNewUserGroupMapperBean

Default: default

property omero.ldap.new_user_group_owner

omero.ldap.new_user_group_owner

A query element to check if user who is being created via the new_user_group setting should be made a “manager”, i.e. owner, of the queried group. E.g. omero.ldap.new_user_group_owner=(owner=@{dn}) will use the ‘manager’ attribute to set the ‘owner’ flag in the database. This query element is appended to any query used by new_user_group with an AND.

This property is not used by new_user_group type ‘default’ and only potentially by :bean:.

Default: [empty]

property omero.ldap.password

omero.ldap.password

LDAP server bind password (if required; can be empty)

Default: [empty]

property omero.ldap.read_timeout

omero.ldap.read_timeout

Sets com.sun.jndi.ldap.read.timeout on the Spring LDAP default security context source environment. The context source is responsible for interacting with JNDI/LDAP.

This timeout is specified in milliseconds and controls the amount of time JNDI/LDAP will wait for a response from the LDAP server. When connecting to a server using SSL this timeout also applies to the SSL handshake process.

A timeout less than or equal to zero means that no timeout will be observed and that the OMERO server will wait indefinitely for LDAP replies. Such a timeout should be used with extreme caution, especially when using SSL and/or without a connection pool, as connectivity issues may then cause your server to no longer be able to create new sessions.

For more information on what this JNDI/LDAP property does, see https://docs.oracle.com/javase/tutorial/jndi/newstuff/readtimeout.html

Default: 5000

Whether or not values from LDAP will be synchronized to OMERO on each login. This includes not just the username, email, etc, but also the groups that the user is a member of.

Note

Admin actions carried out in the clients may not survive this synchronization e.g. LDAP users removed from an LDAP group in the UI will be re-added to the group when logging in again after the synchronization.

Default: false

  • read - whether or not users who have READ access to the objects can access the binary.

  • image - whether or not images are to be considered accessible as a rule.

  • plate - whether or not plates and contained HCS objects are to be considered accessible as a rule. This includes wells, well samples, and plate runs.

Though the order of the components of the property are not important, the order that they are listed above roughly corresponds to their priority. E.g. a -write value will override +plate.
