Checked for relevance on 27-JAN-2013
GOAL
What is the purpose of each of the variables defined in the context file?
SOLUTION
This note gives list of Context Variables with details in short for Oracle Applications Release 12.
A) Context Information:
s_contextserialThis value is automatically updated each time the context variable values are updated through the Oracle Applications Manager.Context Type
s_contexttypeType of the context - whether it is an Applications context or a Database context.Location of the Applications Context File
s_contextfileLocation of the Applications context file.
B) Applications system information:
Name of the Oracle Applications system which this context points to.Database SIDs_dbSid
Database SID for the system.Database Names_dbGlnam
Global Database name for the system. The value of this variable shall be the same as the Database SID on non-RAC environments. On RAC-environments, this name would be the same for all cluster nodes while the Database SID would be different for each cluster node.Database SID in Lower Cases_dbSidLower
Database SID in lower case for the system.
C) System Configurations (oa_system_config) :
YES/NO, denoting if Database Server is enabled in this context.TIER_ADMINs_isAdmin
YES/NO denoting if Admin Server is enabled in this contextTIER_WEBs_isWeb
YES/NO denoting if Web Server is enabled in this contextTIER_FORMSs_isForms
YES/NO denoting if Forms Server is enabled in this contextTIER_FORMSDEVs_isFormsDev
YES/NO denoting if Forms Server is enabled in this contextTIER_NODEs_isConc
YES/NO denoting if Concurrent Processing Server is enabled in this contextTIER_NODEDEVs_isConcDev
YES/NO denoting if Concurrent Processing Server is enabled in this contextTechStack Config Options_techstack
This is automatically supplied to Autoconfig. Since R12 supports only the 10.1.3 techstack, this variable can take only the value 'as1013'.Automatic NetService Files Generation Config Options_tnsmode
The tnsnames.ora file is generated from the database when this option is set to 'generateTNS'.Applications versions_apps_version
This stores the applications version.Apache modes_apache_mode
This variable is used to specify whether Apache should be run in the 'Normal' mode or in the 'Restricted' mode. Apache Restricted Mode is used when Oracle Applications need to be brought down for maintenance purposes. In this mode, during downtime normal users would be redirected to a standard 'downtime' URL displaying the downtime details while the privileged users like System Administrators would be able to monitor patches through OAM. This variable should be in sync with 's_restricted_mode_comment'. For running Apache in the NORMAL mode set this variable to NORMAL and 's_restricted_mode_comment' to #.
For RESTRICT mode set this variable to RESTRICT and 's_restricted_mode_comment' to null value.IAS versions_ias_versionThis variable stores the Oracle Application Server version.
D) Users (oa_users):
The database 'SYS' userApplications 'APPS' Users_apps_user
The applications 'APPS' userApplications 'APPLSYS' Users_applsys_user
The applications 'APPLSYS' user.CP Users_cp_user
This username will be used for starting and stopping the Concurrent Manager. By default, this variable is set to SYSADMIN which is the default username of the System Administrator.Applications 'GUEST' Users_guest_user
The applications 'GUEST' userApplications 'GUEST' Passwords_guest_pass
The applications 'GUEST' password.Applications 'GWYUID' Users_gwyuid_user
The applications 'GWYUID' user.Applications 'GWYUID' Passwords_gwyuid_pass
The applications 'GWYUID' password.
E) Customer Info(customer_info):
Metalink ID of the customerCustomer Country Codes_country_code
This variable is used while configuring the
Oracle Configuration Manager.
F) Language Settings(nls_settings):
Defines the NLS territory which determines cultural conventions such as local time, date, numeric, and monetary conventions. By default, this value is set to 'America'.Base Languages_base_lang
Base Language for the Oracle Applications System. By default, this variable is set to 'American English'. For a list of all supported languages, please refer to the Oracle Applications Installation Manual.Environment Languagess_env_langs
The variable was created to contain the list of all languages supported on the particular environment. This should have includes the Base Language as well as all the Installed Languages. However, this context variable is never updated when support is added for new languages. Hence, this context variable value is not in sync with the actual list of languages supported on the R12 instance, thus leading to confusion, so the variable will be removed starting from version 120.271.12010000.18 of the file adxmlctx.tmp. For a list of all supported languages, please refer to the Oracle Applications Install Manual.

The maximum allowed value for this variable depends on the capacity of the system and also on the number of simultaneous users. By default, the value of this variable is set to '0'.Number of http requests allowed per connections_maxkeepalive_requestsThis directive sets the number of http requests allowed per connection when KeepAlive directive is set to ON. The maximum allowed value for this variable depends on the capacity of the system and also on the number of simultaneous users. By default, this is set to '0'.Number of minimum idle http server processess_minspare_serversThis directive sets the desired minimum number of idle http server processes.Number of maximum idle http server processess_maxspare_serversThis directive sets the desired maximum number of idle http server processes.Number of Oracle HTTP Server child processes created on startups_startServers
Sets the value of the Oracle HTTP (Apache) server directive 'StartServers' in httpd.conf. StartServers directive sets the number of child server processes created on startup. As the number of processes is dynamically controlled depending on the load, there is usually little reason to adjust this parameter. For more details, please refer tohttp://download.oracle.com/docs/cd/B15904_01/web.1012/q20206/mod/mpm_common.html#startserversOracle HTTP Server Limit Request Field Sizes_limitrequestfieldsizeThe LimitRequestFieldSize directive allows the server administrator to reduce or increase the limit on the allowed size of an HTTP request header field. A server needs this value to be large enough to hold any one header field from a normal client requestOracle HTTP Server Limit Request Fields_limitrequestfields
The LimitRequestFields directive allows the server administrator to modify the limit on the number of request header fields allowed in an HTTP request. A server needs this value to be larger than the number of fields that a normal client request might include. The number of request header fields used by a client rarely exceeds 20, but this may vary among different client implementations, often depending upon the extent to which a user has configured their browser to support detailed content negotiationOracle HTTP Server Limit Request Bodys_limitrequestbodyThe LimitRequestBody directive allows the user to set a limit on the allowed size of an HTTP request message body within the context in which the directive is given (server, per-directory, per-file or per-location). If the client request exceeds that limit, the server will return an error response instead of servicing the request. The size of a normal request message body will vary greatly depending on the nature of the resource and the methods allowed on that resourceOracle HTTP Server Limit Request Lines_limitrequestlineThe LimitRequestLine directive allows the server administrator to reduce the limit on the allowed size of a client's HTTP request-line below the normal input buffer size compiled with the server. Since the request-line consists of the HTTP method, URI, and protocol version, the LimitRequestLine directive places a restriction on the length of a request-URI allowed for a request on the server. A server needs this value to be large enough to hold any of its resource names, including any information that might be passed in the query part of a GET requestHelp Web Agents_help_web_agentIf HELP_WEB_AGENT profile is set, the value is used for the construction of all Help related URLs. This allows multiple application installations to share a common help system. Optional override.Custom SQL locations_customsql_pathCustom SQL reports feature within OAM lets users generate HTML and text reports based on the SQL scripts they register.Applications Session Timeouts_sesstimeoutSets the value of EBS profile option ICX_SESSION_TIMEOUT via afwebprf.sql. The value of s_sesstimeout is specified in milliseconds, but the value of the profile option ICX_SESSION_TIMEOUT is set in minutes. The ICX: Session Timeout profile sets the maximum number of minutes to wait before invalidating an idle ICX Session.OC4J Session Timeouts_oc4j_sesstimeoutDefines OC4J's servlet session timeout in minutes. It is specified in orion-web.xml of all the web modules deployed under each OC4J instances. A negative value indicates no timeout. A value of 0 results in an immediate timeout. Default value is 30 minutes. The value for the OC4J session timeout should be equivalent to or higher than the Applications session timeout (s_sesstimeout). For more details, please refer tohttp://download.oracle.com/docs/cd/B25221_04/web.1013/b14426/sessions.htmJInitiator Progress Dialogs_java_showprogressFeature to show the progress of downloading of JInitiator JAR files.Ohs log rotation times_ohs_log_rotation_timeThis variable specifies the Hour of day when opmn process will rotate its log file.

Acceptable values are true or falseEnable/Disable AOL security context and NLS state checks_fnd_jdbc_context_checkThis variable indicates whether the AOL security context and NLS state should be obtained from the database server session instead of the java client when the connection is returned to the pool. Acceptable values are true or falseFree pl/sql states_fnd_jdbc_plsql_resetThis variable indicates whether the pl/sql state should be freed before the applications database connection pool gives the connection to the client.JDBC process escapes_jdbc_proc_escThis variable is used to enable or disable JDBC escape processing mechanism. Changing this parameter value has performance implications.Maximum capacity of JDBC Cached Buffer Sizes_jdbc_max_cached_buffersizeThis variable is used in the DBC file to set the maximum capacity of JDBC cached buffer. A buffer whose capacity is bigger than this value is not pooled. Changing the value of this variable has performance implications.Custom DBC Parameterss_custom_dbc_paramsThis variable holds a space separated custom dbc parameter list of name value pairs. For e.g. 'param1=value1 param2=value2 param3=value3'. These values will be seeded in to the dbc file during AutoConfig execution.
S) OAFM OC4J (oafm_server):
T) Forms c4ws Server (forms-c4ws_server):
OC4J requires that some java-options be passed to start and stop commands. These options are derived internally by OPMN, are not defined in opmn.xml configuration, and cannot be overridden. This context variable specifies ADDITIONAL java-options used in opmn.xml via the <module-data> for FORMS-C4WS OC4J instance startup. These java-options include JVM parameters and system properties for OC4J. For additional information about these properties please refer to 'Oracle Containers for J2EE Configuration and Administration Guide'. More details on JVM parameters can be found athttp://blogs.sun.com/watt/resource/jvm-options-list.html andhttp://java.sun.com/javase/technologies/hotspot/vmoptions.jspFORMS-C4WS OC4J Optionss_forms-c4ws_oc4j_options
Sets the FORMS-C4WS OC4J runtime options in opmn.xml. OC4J processes require that these options be passed in as part of the start or stop commands. These options cannot be overridden. For more details, please refer tohttp://download.oracle.com/docs/cd/B25221_04/core.1013/b15976/oc4j.htm#i1019859FORMS-C4WS OC4J Instance Stop Parameterss_forms-c4ws_jvm_stop_options
OC4J requires that some java-options be passed to start and stop commands. These options are derived internally by OPMN, are not defined in opmn.xml configuration, and cannot be overridden. This context variable specifies ADDITIONAL java-options used in opmn.xml via the <module-data> for FORMS-C4WS OC4J instance shutdown. These java-options include JVM parameters and system properties for OC4J. For additional information about these properties refer to 'Oracle Containers for J2EE Configuration and Administration Guide'. More details on JVM parameters can be found athttp://blogs.sun.com/watt/resource/jvm-options-list.html andhttp://java.sun.com/javase/technologies/hotspot/vmoptions.jspNumber of JVMs for FORMS-C4WS OC4J Instances_forms-c4ws_nprocs
Specifies the number of java processes OPMN starts for FORMS-C4WS OC4J instance. It is used to set the numprocs parameter of <process-set> tag in opmn.xml. Refer tohttp://download.oracle.com/docs/cd/B25221_04/core.1013/b15976/common.htm for more details.Enable FORMS-C4WS OC4J Access logs_forms-c4ws_oc4j_enable_access_log
This context variable is used to enable/disable OC4J access log for FORMS-C4WS application. Setting the value of this variable to 'TRUE' will enable the access log.X11 Display for FORMS-C4WS OC4J Service Instances_forms-c4ws_display
Used by the FORMS-C4WS OC4J Service Instance, this display must always be accessible during runtime. Should be set to an active and authorized X Windows display, and should point to a machine that is always available to the Applications instance.Enable headless operation for Java, for FORMS-C4WS OC4J Service Instances_forms-c4ws_java_awt_headless
'Headless' operation refers to the ability to run a Java program without a monitor, mouse or keyboard. In UNIX environments, it usually means that X or an equivalent windowing system does not have to be present. Headless Java operation would mean that a server side Java program should be able to use the full J2SE or J2EE API without a GUI environment being present. This means that all AWT calls to manipulate components, graphics, fonts, printing etc. should be functional. Set this value to true to enable headless operation or set it to false (default value) to disable it.
