ERROR:
ORA-12157: TNS:internal network communication error

Hi,
This is my problem. I dont know why I face this bug. some document says the problem is with host with respect to listener and some says problem with respect to processes I have to increase

this what the value set in initora10g
*.processes=150

I couldn't find any issue with these because I can able to ping to the host name and IP address


this is how my listener is configured:

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.113.47.110)(PORT = 1521))
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = ora10g)
(ORACLE_HOME = /export/home/oracle/10.2.0)
(SID_NAME = ora10g)
)
(SID_DESC =
(GLOBAL_DBNAME = ora9i)
(ORACLE_HOME = /storedge1/oracle/product/9.2.0.4.0)
(SID_NAME = ora9i)
)
(SID_DESC =
(GLOBAL_DBNAME = reliance)
(ORACLE_HOME = /export/home/oracle/10.2.0)
(SID_NAME = reliance)
)
)

Can anyone help me to resove this issue

With regards
Boo
