OCI Error ORA (status = 1034-ORA-01034: ORACLE not available and ORA-27101: shared memory realm does not exist during Dblogin Goldengate

Hi,

You can get ” OCI Error ORA (status = 1034-ORA-01034: ORACLE not available and ORA-27101: shared memory realm does not exist  ” error during Dblogin in Goldengate.

Details of error are as follows.

[ggate@msdbadm01 19.1.0.0.4]$ ./ggsci

SETENV (ORACLE_SID=MSDB)
SETENV (ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_home)

Or Check your TNS Alias if it contains correct values for SID and IP.

I have created a static listener for the Goldengate as follows, then use it. Add following statis listener description into listener.ora under $ORACLE_HOME/network/admin. Then start listener.

LISTENER_GG =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.63.35)(PORT = 1521))
)
)

SID_LIST_LISTENER_GG =
(SID_LIST =
(SID_DESC =
(SID_NAME = MSDB1)
(ORACLE_HOME = /u01/app/oracle/product/12.2.0/db_home)
(SERVICE_NAME = MSDB)
)
)


lsnrctl start LISTENER_GG 

Now When I try to run dblogin command, it is successful. The problem is related with the registered listener in my case.

So I have created a new static listener, then it works fine as follows.

[ggate@msdbadm01 19.1.0.0.4]$ ./ggsci
