Error in Timesten While Alter table in oracle

Question

Hello DB experts,
I am getting below error while my application statrtup.
"Exception while caching Rating System Parameter Details.[TimesTen][TimesTen 11.2.2.2.0 ODBC Driver][TimesTen]TT0871: Column VALUE cannot be set to null "
We have perfomed  below activities.
1) Not null constraint is created on one table which is in oracle.
2)  My applicaiton is up with timesten
3) Not null constraint is removed from oracle.
4) null data are inserted in that column ,
Please not that  the table on which constraint is created/removed  was not cached in timesten . its oracle table only.
Now my question is we wanted to know how timesten will work in above situation.

Answer 1

The DSN definition from sys.odbc.ini file
[ocsdev]
Driver=/u02/app/TimesTen/tt1122/lib/libtten.so
DataStore=/u031/odbcqa/ttTest
PermSize=1000
TempSize=400
PLSQL=1
DatabaseCharacterSet=WE8MSWIN1252
OracleNetServiceName=orcl
Passthrough=1
UID=crestelxxxdevg5
PWD=crestelxxxdevg5
OracleId=crestelxxxevg5
OraclePwd=crestelxxxdevg5
2.    Details of any cache groups you do have defined in TimesTen.
CREATE asynchronous writethrough CACHE GROUP CUST_PACKAGE
FROM  TBLCUSTOMERPACKAGE
CUSTOMERPACKAGEID  NUMBER ,
VALIDFROMDATE    DATE,
VALIDTODATE   DATE,
CUSTOMERID    NUMBER,
SERVICEID    NUMBER,
PRIORITY    NUMBER,
PACKAGEID    NUMBER,
PRIMARY KEY ("CUSTOMERPACKAGEID"))
   UNIQUE HASH ON (CUSTOMERPACKAGEID) PAGES = 4000 ;
3 ) Details of the Oracle table that was altered (table name, column for which the NULL/NOT NULL constraint was changed, any primary/foreign key relationship between this table/column and any cached table/column).
CREATE TABLE "TBLMRATINGCONFIG"
    "RATINGCONFID"         CHAR(7 BYTE) CONSTRAINT "NN_RATINGCONFIG_RATINGCONFID" NOT NULL ENABLE,
    "NAME"                 VARCHAR2(50 BYTE) CONSTRAINT "NN_RATINGCONFIG_NAME" NOT NULL ENABLE,
    "ALIAS"                VARCHAR2(50 BYTE) CONSTRAINT "NN_RATINGCONFIG_ALIAS" NOT NULL ENABLE,
    "DESCRIPTION"          VARCHAR2(2000 BYTE),
    "VALUE"                VARCHAR2(100 BYTE) CONSTRAINT "NN_RATINGCONFIG_VALUE" NOT NULL ENABLE,
    "PARAMETERTYPEID"      CHAR(5 BYTE) CONSTRAINT "NN_RATINGCONFIG_ID" NOT NULL ENABLE,
    "PARAMETERVALUESOURCE" VARCHAR2(255 BYTE),
    "COMMONSTATUSID"       CHAR(5 BYTE) CONSTRAINT "NN_RATINGCONFIG_COMMONSTATUSID" NOT NULL ENABLE,
    "SYSTEMGENERATED"      CHAR(1 BYTE) CONSTRAINT "NN_RATINGCONFIG_SYSGEN" NOT NULL ENABLE,
    "CREATEDATE" DATE CONSTRAINT "NN_RATINGCONFIG_CREATEDATE" NOT NULL ENABLE,
    "LASTMODIFIEDDATE" DATE CONSTRAINT "NN_RATINGCONFIG_LASTMODIFIEDT" NOT NULL ENABLE,
    "CREATEDBYSTAFFID"      CHAR(7 BYTE) CONSTRAINT "NN_RATINGCONFIG_CRSTAFF" NOT NULL ENABLE,
    "LASTMODIFIEDBYSTAFFID" CHAR(7 BYTE) CONSTRAINT "NN_RATINGCONFIG_MODIFIEDSTAFF" NOT NULL ENABLE,
    "STATUSCHANGEDATE" DATE,
    "SERVICEID"            CHAR(8 BYTE) CONSTRAINT "NN_RATINGCONFIG_SERVICEID" NOT NULL ENABLE,
    "JAVASCRIPTREGEX"      VARCHAR2(255 BYTE),
    "SYSTEMPARAMETERGROUP" NUMBER,
    "DISPLAYORDER"         NUMBER(3,0),
    "ALERTMSG"             VARCHAR2(200 BYTE),
    CONSTRAINT "PK_RATINGCONFIG" PRIMARY KEY ("RATINGCONFID")
In above script i am removing constraint on "value" column which is having  not null constraint.
4) column "value" having such data like 'null'
5) Error
"Exception while caching Rating System Parameter Details.[TimesTen][TimesTen 11.2.2.2.0 ODBC Driver][TimesTen]TT0871: Column VALUE cannot be set to null "
