Verification of CONTOKEN in SYSPACKAGE DBRMLIB LOADLIB

Verification of Consistency token in SYSPACKAGE, DBRMLIB and LOADLIB.

When a Job abends at a program due to bind error with SQL code of -805 or -818 then generally there is issue with consistency token (often referred as CONTOKEN). These kind of abends can be easily fixed if we can find where the CONTOKEN mismatch occurs.

STEP1:- CONTOKEN in Package

RUN the following query 

SELECT NAME, CONTOKEN, COLLID, PDSNAME FROM SYSIBM.SYSPACKAGE WHERE NAME=’MODULE’

AND COLLID=’COLLID’

Provide the name of the module in “NAME” and Collection name in “COLLID”

In the Query output dataset locate the CONTOKEN value and view it in HEX mode (by issuing HEX ON command)

The contoken in the above image is 

1DE6102A

8A19F405

which is 

18DAE1691F0420A5

STEP2:- CONTOKEN in DBRMLIB

The “PDSNAME” field above will indicate the DBRMLIB used for binding the module.

Goto the DBRMLIB

Open the DBRM for the above module, it will have the same name as the module name.

Search for the contoken in hex mode by entering the following command

F X’18DAE1691F0420A5

(The CONTOKEN in the DBRM is generally at the 25th position as shown in the figure above)

Note:- 

If the CONTOKEN in Step1 and Step2 does not match then Run the Bind job to fix the

inconsistency. Bind Job is going 

to update the CONTOKEN in the SYSIBM.SYSPACKAGE Table.

STEP3:- CONTOKEN in loadlib

-Since the date and time part of the CONTOKEN are swapped in loadlib, you will have to 

split the CONTOKEN found in SYSPACKAGE table in two halves of 8 chars each and then swap their positions.

First Half

18DAE169

Second Half

1F0420A5

Swapping positions and joining them back will result in the CONTOKEN

1F0420A518DAE169

Go to the load library where the load to be checked is present.

CONTOKEN in Composite load of the link

Open the composite load and 

search for the reversed CONTOKEN in hex mode in the composite load 

F X’1F0420A518DAE169′

Note:-

If its found, no problem and if not then you need to process the link to fix the issue.

CONTOKEN in load of the program

Open the load object for the program, it generally has the same name as the module name.

Now search for the reversed CONTOKEN in hex mode in the load of the program using command

F X’1F0420A518DAE169′

Note:- If the CONTOKEN is found then its fine and if not then you will need to recompile and also relink(if

composite load also doesnt has this) to fix the issue.
