Sybase Funktionen

Einführung

Anforderungen

Installation

Um die Sybase-Datenbankunterstützung zu aktivieren, müssen Sie PHP mit der Option --with-sybase[=DIR]konfigurieren. DIR ist das Sybase Wurzelverzeichnis, welches im Normalfall /home/sybase ist. Zur Aktivierung der Sybase-CT Unterstützung, muss als PHP-Konfigurationsparameter --with-sybase-ct[=DIR] angegeben werden. Auch hier ist DIR das Sybase Wurzelverzeichnis, dass normalerweise /home/sybase ist.

Laufzeit Konfiguration

Das Verhalten dieser Funktionen wird durch Einstellungen in der php.ini beeinflusst.

Sybase Konfigurationsoptionen

Name	Standardwert	Änderbar
sybase.allow_persistent	"On"	PHP_INI_SYSTEM
sybase.max_persistent	"-1"	PHP_INI_SYSTEM
sybase.max_links	"-1"	PHP_INI_SYSTEM
sybase.interface_file	"/usr/sybase/interfaces"	PHP_INI_SYSTEM
sybase.min_error_severity	"10"	PHP_INI_ALL
sybase.min_message_severity	"10"	PHP_INI_ALL
sybase.compatability_mode	"Off"	PHP_INI_SYSTEM
magic_quotes_sybase	"Off"	PHP_INI_ALL

Hier eine kurze Erklärung der Konfigurationsoptionen:

sybase.allow_persistent boolean

Whether to allow persistent Sybase connections.

sybase.max_persistent integer

The maximum number of persistent Sybase connections per process. -1 means no limit.

sybase.max_links integer

The maximum number of Sybase connections per process, including persistent connections. -1 means no limit.

sybase.min_error_severity integer

Minimum error severity to display.

sybase.min_message_severity integer

Minimum message severity to display.

sybase.compatability_mode boolean

Compatability mode with old versions of PHP 3.0. If on, this will cause PHP to automatically assign types to results according to their Sybase type, instead of treating them all as strings. This compatability mode will probably not stay around forever, so try applying whatever necessary changes to your code, and turn it off.

magic_quotes_sybase boolean

If magic_quotes_sybase is on, a single-quote is escaped with a single-quote instead of a backslash if magic_quotes_gpc or magic_quotes_runtime are enabled.

Hinweis: Note that when magic_quotes_sybase is ON it completely overrides magic_quotes_gpc . In this case even when magic_quotes_gpc is enabled neither double quotes, backslashes or NUL's will be escaped.

Sybase-CT configuration options

Name	Default	Changeable
sybct.allow_persistent	"On"	PHP_INI_SYSTEM
sybct.max_persistent	"-1"	PHP_INI_SYSTEM
sybct.max_links	"-1"	PHP_INI_SYSTEM
sybct.min_server_severity	"10"	PHP_INI_ALL
sybct.min_client_severity	"10"	PHP_INI_ALL
sybct.hostname	NULL	PHP_INI_ALL
sybct.deadlock_retry_count	"-1"	PHP_INI_ALL

Hier eine kurze Erklärung der Konfigurationsoptionen:

sybct.allow_persistent boolean

Whether to allow persistent Sybase-CT connections. The default is on.

sybct.max_persistent integer

The maximum number of persistent Sybase-CT connections per process. The default is -1 meaning unlimited.

sybct.max_links integer

The maximum number of Sybase-CT connections per process, including persistent connections. The default is -1 meaning unlimited.

sybct.min_server_severity integer

Server messages with severity greater than or equal to sybct.min_server_severity will be reported as warnings. This value can also be set from a script by calling sybase_min_server_severity(). The default is 10 which reports errors of information severity or greater.

sybct.min_client_severity integer

Client library messages with severity greater than or equal to sybct.min_client_severity will be reported as warnings. This value can also be set from a script by calling sybase_min_client_severity(). The default is 10 which effectively disables reporting.

sybct.hostname string

The name of the host you claim to be connecting from, for display by sp_who. The default is none.

sybct.deadlock_retry_count int

Allows you to to define how often deadlocks are to be retried. The default is -1, or "forever".
