ORA-06121: NETTCP: access failure
Cause: The host’s SQL*Net TCP/IP server was unable to test the accessibility of the SID mapping file (specified in CONFIG.ORA) associated with this connection request. See the SQL*Net TCP/IP server log file for more details.
Action: Contact your customer support representative.
ORA-06122: NETTCP: setup failure
Cause: The host’s SQL*Net TCP/IP server was unable to set up the appropriate environment to service this connection request. See the SQL*Net TCP/IP server log file for more details.

Action: Contact your customer support representative.

ORA-06124: NETTCP: timeout waiting for ORASRV
Cause: The ORACLE server process was started but failed to respond after N secs.
Action: For heavily loaded systems this is not an uncommon occurrence. Increase the value of N (the default is 30) by placing the following entry in the CONFIG.ORA file: SQLNET ORASRV_WAIT = <no. of secs> which will come into effect the next time the SQL*Net TCP/IP server is started.
ORA-06125: NETTCP: ORASRV exited unexpectedly
Cause: The ORACLE server process was started but exited unexpectedly. Possible causes:
1. Insufficient quotas to run ORASRV
2. ORACLE is not installed See the ORASRV output file for more details; the file will be in the ORA_SQLNET directory and will have a name of the form: ORA_SRVTnn_<SID>.OUT
Action: If appropriate action is not obvious from the ORASRV output file then contact your customer support representative.
ORA-06126: NETTCP: ORASRV unable to open network connection
Cause: The ORACLE server process was started but was unable to open the socket passed to it by TCPSRV.
Action: Contact your customer support representative.

ORA-06127: NETTCP: unable to change username
Cause: The host’s SQL*Net TCP/IP server could not establish a PROXY LOGIN connection because the client username is unknown (to the host OS).
Action: Create new user account on host.
ORA-06128: NETTCP: unable to create mailbox
Cause: The host’s SQL*Net TCP/IP server was unable to create a mailbox (needed for IPC communication with the ORACLE server process). See the SQL*Net TCP/IP server log file for more details.
Action: Contact your customer support representative.
ORA-06129: NETTCP: unable to transfer socket ownership to ORASRV
Cause: The host’s SQL*Net TCP/IP server was unable to transfer the network communication handle to the ORACLE server process. See the SQL*Net TCP/IP server log file for more details.
Action: Contact your customer support representative.
ORA-06130: NETTCP: host access denied
Cause: The host’s SQL*Net TCP/IP server rejected this connection request because the client node does not have access privilege – as determined by the contents of the Valid Node Table (VNT), a component of the host’s CONFIG.ORA.
Action: To grant access, add appropriate entry to the host’s VNT.
