10G grid shows database down when it is not

10G grid shows database down when it is not

Does anyone have a solution for this 10G Grid / agent problem on windows
2000?

After installing the 10g agent (10.1.0.2) on various windows 2000
servers, the 10G grid (10.1.0.3) shows the database is up but after
about 5 minutes it shows the database as down with error:

Failed to connect to database: ORA-12538 (See ORA-12538.ora-code.com): TNS:no such protocol adapter
(DBD ERROR: OCIServerAttach).

The database is not down.

The following error appears in the agent trace file (emagent.trc)=20

Process stderr =3D em_error=3DCould not connect to
dbsnmp/(DESCRIPTION=3D(ADDRESS=3D(PROTOCOL=3DTCP)(HOST=3Dgenusapp1.canfor=
.ca)(Po
rt=3D1521))(CONNECT_DATA=3D(SID=3DP92A)))
: ORA-12538 (See ORA-12538.ora-code.com): TNS:no such protocol adapter (DBD ERROR:
OCIServerAttach)

This happens with both 9.2.0.4 and 8.1.7.4 databases.

Oracle says it is bug # 3512622 but there is no fix at this time.
