Error connecting to DB2 via DRDA gateway for db2

Question

Linux 2 node RAC system version 10.2.0.4. Installed DRDA for db2 LUW version 11.2 into a new home on the existing RAC nodes. Installed and configured and followed note 945879.1. Restarted listener and configured tnsnames.ora successfully on both nodes. TNSPING works for the dg4db2 'SID' created. Created a database link, and when I tested by getting a simple count, I received the following error:
select count(*) from schema.mydb2_table@db2_105
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from DB2_105Here's my listener config:
SID_LIST_LISTENER_NODE1 =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
      (SID_NAME=dg4db2)
      (ORACLE_HOME=/u01/app/oracle/gateway/11_2/)
      (ENVS=LD_LIBRARY_PATH=/u01/app/oracle/gateway/11_2/dg4db2/driver/lib;/u01/app/oracle/product/10.2.0/db_1/lib)
      (PROGRAM=dg4db2)
  )Here's my tnsnames.ora:
dg4db2 =
  (DESCRIPTION=
    (ADDRESS=(PROTOCOL=tcp)(HOST=vip-node1)(PORT=1521))
    (CONNECT_DATA=(SID=dg4db2))
    (HS=OK)
  )Here's the initdg4db2.ora - ip address and obfuscated:
HS_FDS_CONNECT_INFO=[the ip address]:theport/ips,LUW
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
HS_TRANSACTION_MODEL=COMMIT_CONFIRM
HS_FDS_TRANSACTION_ISOLATION=READ_COMMITTED
HS_FDS_SUPPORT_STATISTICS=TRUE
HS_FDS_RESULTSET_SUPPORT=FALSE
HS_FDS_PACKAGE_COLLID=ORACLEGTW
HS_IDLE_TIMEOUT=0And my db link syntax - database name and password obfuscated:
CREATE DATABASE LINK db2_105
CONNECT TO THEDB2DB
IDENTIFIED BY somepassword
USING 'dg4db2'tnsping output:
Used TNSNAMES adapter to resolve the alias

TNS-12505: TNS:listener does not currently know of SID given in connect descriptorNot sure where to go from here troubleshooting-wise. I understand that with 11.2, there is no longer a need to bind packages? Any help is much appreciated.

Answer 1

your listener.ora contains an error in the SID section. you miss a closing bracket for the extproc SID and another SID_DESC for the dg4db2 SID:
SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
) #closing bracket is missing
(SID_DESC = # SID desc is missing
(SID_NAME=dg4db2)
(ORACLE_HOME=/u01/app/oracle/gateway/11_2/)
(ENVS=LD_LIBRARY_PATH=/u01/app/oracle/gateway/11_2/dg4db2/driver/lib;/u01/app/oracle/product/10.2.0/db_1/lib)
(PROGRAM=dg4db2)
After changing the listener.ora, stop and start the listener.
