Reporting users who query the “Active Data Guard” may want that the data be synchronized with Production.<\/p>\n

Others may not care whether LAG has occurred for a few seconds. Minor delays may not be very important for someone. But even they often don’t want longer lags . For example, a user can say that I only tolerate a 5 second lag. This parameter is very helpful for this user.<\/p>\n

For such cases, ORACLE has created the STANDBY_MAX_DATA_DELAY parameter that will be valid at the session level for Standby side. This parameter takes seconds.<\/p>\n

We can set this parameter as session level as follows;<\/p>\n

ALTER SESSION SET STANDBY_MAX_DATA_DELAY = {INTEGER|NONE}<\/pre>\n
STANDBY_MAX_DATA_DELAY Example<\/h3>\n
Lest test it;<\/p>\n
Step1:<\/h4>\n
Check if the Data Guard is working healthy on Primary and Standby.<\/p>\n
