ORA-02068: following severe error tips

Oracle Error Tips by Donald Burleson(S. Karam)

 

The Oracle docs note this on the ora-02068 error:

 

ORA-02068: following severe error from string string
 
Cause: A severe error (disconnect, fatal Oracle error) received from the indicated database link. See following error text.
 

Action: Contact the remote system administrator.

MOSC documents offer information on ORA-02068, On Enterprise Edition of Oracle Server; Version 9207 (occurring on any platform).  This ORA-02068 documents includes actions as follows:


Symptoms: Via Oracle Warehouse Builder, a package performs dml operations via
db link on remote tables, for example truncate and insert. At the end, the
package executes dbms_stats.gather_schema_stats on that remote schema. It
returns the following errors:

ORA-20999: odb_rep_interface.repli_contract: ORA-2068: following severe
error
from ODB_DBLN
ORA-3113: end-of-file on communication channel
ORA-2068: following severe error from ODB_DBLN
ORA-3113: end-of-file on communication channel
ORA-6512: at ""DWRSOURCE.ODB_REP_INTERFACE"", line 446
ORA-6512: at line 2


The remote alert log shows ORA-7445 (null parameters) on an internal select
as shown in the Diagnostics section below.

Intermittently a ora-600[qks3tAssert:1][2304][][] also shows in alert log

The errors (including ORA-02068) begin after patchset 9.2.0.7 on top of release 9.2.0.4 has been applied. The cause is reported as follows:


Cause: The problem is caused by Bug 4439739 Base Bug 3494626 (as confirmed by Bug Diagnostics and Escalations team in Bug 4773592).
 

The solution is in regards to many errors in addition to ORA-02068 in cluding

ORA-600[QKS3TASSERT:1]
ORA-7445 NULL PARAMETERS
ORA-7445 "exception encountered: core dump [%s] [%s]"
ORA-20999
ORA-6512 "at %sline %s"
ORA-2068 following severe error from
ORA-3113 "end-of-file on communication channel"

And should be resolved as follows:

Solution: Do not run gather_schema_stats within the same package. Run the DMLs within the package. Then, when the package execution is done, execute gather_schema_stats.
Alternarively, upgrade to 10.1.0.5 (the bug is fixed in this release).
