because the unqualified SSA already existed on the SSA list and
was not related to the current segment.






Module name: NDPSFSSA

Problem determination: Items 1 (trace parameter = (CMD,REQ,SER)), 2.
Action
Contact Software AG support.

NAT3913: Internal error.

Action
Increase the value of the SIZE parameter in the NDPCPARM parameter
module.

NAT3921: Natural buffer pool not active, or unknown return code.

Text
Natural buffer pool not active, or unknown return code.
Explanation
When calling the Natural buffer pool for a Natural DL/I control block
(NDB, NSB, UDF) request, the buffer pool returned:
   - an unknown return code, or
   - a return code which indicates that the buffer pool is not active.





Module name: NDPSNBPI
Action
Contact Software AG support.

NAT3922: NDB/NSB/UDF not found during de-allocation.

Text
NDB/NSB/UDF not found during de-allocation.
Explanation
An attempt was made to de-allocate a Natural DL/I control block
(NDB, NSB, UDF) from the Natural buffer pool.
However, the control block was not found in the buffer pool.
Action
Contact Software AG support.

NAT3923: Use count gone negative during de-allocation.

Text
Use count gone negative during de-allocation.
Explanation
When de-allocating Natural DL/I control blocks (NDB/NSB/UDF) from the
buffer pool, it was detected that the use count was negative.







Module name: NDPSNBPI
Action
Contact Software AG support.

NAT3924: No space during load into buffer pool.

Text
No space during load into buffer pool.
Explanation
When loading the Natural DL/I control blocks (NDB/NSB/UDF) from
the system file into the buffer pool, there was not enough storage
available in the buffer pool.






Module name: NDPSNBPI
Action
Provide enough storage.

NAT3925: Symbolic checkpoint/restart failed.

Text
Symbolic checkpoint/restart failed.
Explanation
IMS checkpointing was requested in a batch Natural program, through
the provision of user data with the END TRANSACTION statement.
However, this request could not be satisfied because an error was
detected by Natural for DL/I.
Possible reasons for this error:
   - A GETMAIN failed: Natural for DL/I requires a 2000-byte buffer
     for this function.
   - A DL/I status code was returned in response to the XRST call.
   - The XRST call was not issued because it is not supported
     in this environment or with this CMPAT setting.

Module name: NDLRRE00
Action
Increase the REGION size in the JCL.
Check IMS TM logging installation at your site.
Check if your environment (CMPAT setting) supports the XRST call.

NAT3926: Invalid search criterion for HDAM database.

Text
Invalid search criterion for HDAM database.
Explanation
When accessing a HDAM database, either a secondary
index must be used or a condition must be specified
for the root sequence field with relational operator
EQUAL TO. Fields different from the sequence field
are not permitted to prevent excessive sequential
DL/I access.
Use READ PHYSICAL if you want to retrieve root
segments sequentially (in physical sequence).

Module name: NDPRPTSA
Action
Use EQUAL TO as logical operator, or access via alternate index.

NAT3927: FREEMAIN for NCB failed.

Text
FREEMAIN for NCB failed.
Explanation
To copy the NCB from the buffer pool into a work area, a GETMAIN
for the work area is performed. The subsequent FREEMAIN for this
work area failed.

Module name: NDPSNCBI
Action
Contact Software AG support.

NAT3929: Natural for DL/I has not been initialized.

Text
Natural for DL/I has not been initialized.
Explanation
Natural for DL/I service has been requested, but Natural for DL/I
has not been initialized.

Module name: NDLGWDLI
Action
Install Natural for DL/I with a DLISIZE of at least 27 KB;
then start the Natural session again.

NAT3930: NATPSB ON/OFF command not available in IMS environment.

Text
NATPSB ON/OFF command not available in IMS environment.
Explanation
PSB switching under IMS TM is accomplished by using the module
'CMDEFSWX' or 'CMDIRSWX'.
Action
Instead of NATPSB, use one of the above modules.

NAT3931: GETMAIN size exceeds maximum of 32 KB.

Text
GETMAIN size exceeds maximum of 32 KB.
Explanation
Natural DL/I attempts to copy the DL/I CALL parameter list into
a buffer below 16 MB. The GETMAIN for this buffer could not be
executed, because the size requested was greater than the maximum
possible size of 32 KB.

Module name: NDLSIOCX
Action
Contact Software AG support.

NAT3932: GETMAIN failed for buffer below 16 MB.

Text
GETMAIN failed for buffer below 16 MB.
Explanation
Natural DL/I attempts to copy the DL/I CALL parameter list into
a buffer below 16 MB. The GETMAIN for this buffer failed.

Module name: NDLSIOCX
Action
Contact Software AG support.

NAT3933: Now it is too late for BACKOUT TRANSACTION.

Text
Now it is too late for BACKOUT TRANSACTION.
Explanation
The program contains a design error: It attempts to backout updates
which have already been committed. This error can only occur under
CICS in pseudo-conversational mode or under IMS TM. The most likely
reason is that a terminal I/O has forced the end of the logical
transaction; that is, internally a SYNCPOINT command has already been
executed by the TP monitor at the time when the BACKOUT TRANSACTION
statement is executed. Nevertheless, Natural for DL/I has executed
a SYNCPOINT ROLLBACK command. This means that the actual scope of
the BACKOUT TRANSACTION is different from the expected one.
Action
Correct error in program.

NAT3934: FREEMAIN for I/O area failed.

Text
FREEMAIN for I/O area failed.
Explanation
Internal error.

Module names: NDLSIOBA/NDLSIOCX.
Action
Contact Software AG support.

NAT3935: :1: locked in bufferpool blacklist.

Text
... locked in bufferpool blacklist.
Explanation
A Natural for DL/I object - NDB, NSB or UDF - could not be loaded
into the buffer pool, because it has been locked from execution
via the Blacklist Maintenance function of the SYSBPM utility.

Module name: NDLSSHGE
Action
Contact your Natural administrator to delete the blacklist entry.

NAT3936: GSAM records cannot be deleted or updated.

Text
GSAM records cannot be deleted or updated.
Explanation
The database accessed is a GSAM database.
You cannot delete or update records in a GSAM database.
This is a GSAM restriction.

Module name: NDLRPTSA,NDLRN100
Action
Remove DELETE or UPDATE statement from your program.

NAT3937: Segment length exceeded.

Text
Segment length exceeded.
Explanation
The length of the retrieved segment is larger than the maximum length
defined to Natural for this segment type, i.e. the definitions for
DL/I and NDL are not in synchronization.
The most probable reason is that the segment length was increased
using DBDGEN but the corresponding execution of NATDBD was omitted.

Module name: NDLRGNEX
Action
Re-run the NATDBD procedure against the DBD.

NAT3938: Not enough storage in WORK buffer.

Text
Not enough storage in WORK buffer.
Explanation
During format buffer analysis, Natural for DL/I could not acquire
storage from the WORK buffer for another format buffer entry because
the WORK buffer is full.
Module name: NDLSFBSA
Problem determination: Items 1 (trace = (CMD,REQ,SER)), 2, 10.
Action
Increase the related WORK parameter WORKLGH in the NDLPARM module.
