Solution:

Step 1: Take a backup of sqlnet.ora file from the below path in OBIEE MT server.

For 12.2.1.3 and lower: [DOMAIN_HOME]/config/fmwconfig/bienv/core/sqlnet.ora

For 12.2.1.4 and higher: [DOMAIN_HOME]/bidata/components/core/serviceinstances/ssi/oracledb/sqlnet.ora

Step 2: Add and provide proper value for sqlnet.expire_time in OBIEE sqlnet.ora file

SQLNET.INBOUND_CONNECT_TIMEOUT=360
SQLNET.SEND_TIMEOUT=1200
SQLNET.RECV_TIMEOUT=1200
sqlnet.expire_time=20

Step 3: Restart the services.
