名词解释

1)fal_server

The Oracle docs note that fal_server specifies the FAL (fetch archive log) server for a standby database. The value for fal_server is an Oracle*Net service name, which is assumed to be configured properly on the standby database system to point to the desired FAL server.

2)LOG_FILE_NAME_CONVERT

Property	Description
Parameter type	String
Syntax	LOG_FILE_NAME_CONVERT = 'string1' , 'string2' , 'string3' , 'string4' , ... Where: string1 is the pattern of the primary database filename string2 is the pattern of the standby database filename string3 is the pattern of the primary database filename string4 is the pattern of the standby database filename You can use as many pairs of primary and standby replacement strings as required. You can use single or double quotation marks. The following are example settings that are acceptable: LOG_FILE_NAME_CONVERT = '/dbs/t1/','/dbs/t1/s_','dbs/t2/ ','dbs/t2/s_'
Default value	There is no default value.
Modifiable	ALTER SESSION
Basic	No

   LOG_FILE_NAME_CONVERT converts the filename of a new log file on the primary database to the filename of a log file on the standby database. If you add a log file to the primary database, you must add a corresponding file to the standby database.

   If you specify an odd number of strings (the last string has no corresponding replacement string), an error is signalled during startup. If the filename being converted matches more than one pattern in the pattern/replace string list, the first matched pattern takes effect. There is no limit on the number of pairs that you can specify in this parameter (other than the hard limit of the maximum length of multivalue parameters).

   When the standby database is updated, this parameter converts the log file name on the primary database to the log file name on the standby database. The file must exist on the standby database and must be writable or the recovery process will halt with an error.
