Alter Application (Aggregate Storage)

Click here for non-aggregate storage version

Permission required: Application Manager.

Syntax

Description of the illustration altapp_as.gif

You can change the following application-wide settings using alter application.

Keywords

set minimum permission

Grant all users a minimum level of permission to all databases in the application. Users with higher permissions than this minimum are not affected.

set variable

Assign a string value to an existing substitution-variable name. If the variable does not exist, first create it using add variable. Substitution variables may be referenced by calculations in the application.

set cache_size

Set the maximum size to which the aggregate storage cache may grow. The aggregate storage cache grows dynamically until it reaches this limit. This setting takes effect after you restart the application. To check the currently set limit, use the following MaxL statement:

query application APP-NAME get cache_size;

If the ASODEFAULTCACHESIZE configuration setting is in use, either at application or server level, this MaxL statement has no effect.

set type unicode_mode

Migrate an application to Unicode mode. Migration to Unicode mode cannot be reversed.

load database

Start (by loading into memory) an idle database. The statement will fail if you do not have at least read privilege for the database.

unload database

Stop (by unloading from memory) an active database. The statement will fail if you do not have at least read privilege for the database.

enable startup

Permit all users to load (start) the application. This only applies to users who have at least read privilege for the application. Startup is enabled by default.

disable startup

Prevent all users from loading (starting) the application. Startup is enabled by default.

enable autostartup

Start the application automatically when Essbase Server starts. By default, autostartup is disabled.

disable autostartup

Do not start the application automatically when Essbase Server starts. By default, autostartup is disabled.

enable commands

Allow all users with sufficient permissions to make requests to databases in the application. Use to reverse the effect of disable commands. The disable commands setting remains in effect only for the duration of your session. By default, commands are enabled.

disable commands

Prevent all requests to databases in the application, including non-data-specific requests, such as viewing database information or changing database settings. All users are affected, including other administrators. Administrators are affected by this setting as a safety mechanism to prevent accidental updates to databases during maintenance operations. This setting remains in effect only for the duration of your session. The setting takes effect immediately, and affects users who are currently logged in, as well as users who log in later during your session.

Caution:

If performing maintenance operations that require disabling commands, you must make those maintenance operations within the same session and the same script as the one in which commands were disabled.

By default, commands are enabled.

enable updates

Allow all users with sufficient permissions to make requests to databases in the application. Use to reverse the effect of disable updates. Disabling updates remains in effect only for the duration of your session. By default, updates are enabled.

disable updates

Prevent all users from making requests to databases in the application. Use before performing update and maintenance operations. The disable updates setting remains in effect only for the duration of your session.

Caution:

If performing maintenance operations that require updates to be disabled, you must make those maintenance operations within the same session and the same script as the one in which updates were disabled. By default, updates are enabled.

enable connects

Allow all users with sufficient permissions to make connections to databases in the application. Use to reverse the effect of disable connects. By default, connections are enabled.

disable connects

Prevent any user with a permission lower than Application Manager from making connections to the databases that require the databases to be started. Database connections remain disabled for all databases in the application, until the application setting is re-enabled by the administrator.

By default, connections are enabled.

enable security

When security is disabled, Essbase ignores all security settings in the application and treats all users as Application Managers. By default, security is enabled.

disable security

When security is disabled, Essbase ignores all security settings in the application and treats all users as Application Managers. By default, security is enabled.

comment

Enter an application description (optional). The description can contain up to 80 characters.

clear logfile

Delete the application log located in the application directory. A new log is created for entries recording subsequent application activity.

add variable

Create an application-level substitution variable by name, and optionally assign a string value for the variable to represent. You can assign or change the value later using set variable. A substitution variable acts as a global placeholder for information that changes regularly. Substitution variables may be referenced by calculations and report scripts.

If substitution variables with the same name exist at server, application, and database levels, the order of precedence for the variables is as follows: a database level substitution variable supersedes an application level variable, which supersedes a server level variable.

drop variable

Remove a substitution variable and its corresponding value from the application.

rename to

Rename the application. When you rename an application, the application and the application directory (ARBORPATH\app\appname) are renamed.

Example

alter application ASOsamp set cache_size 64MB;

Sets the maximum size of the aggregate storage cache to 64 MB.

alter application ASOsamp disable commands;

Prevents all users from making requests to the application scope. Use this statement before performing application-wide update and maintenance operations.

alter application ASOsamp comment 'Aggregate storage application';

Attaches a descriptive comment to the ASOsamp application.
