The names of the directory and file to which undecided transaction information is output are as follows.

• Undecided transaction information is output to the directory $DCDIR/spool/dctrninf/ of the node in which the transaction service exists.
• Every time full recovery of transaction service occurs, undecided transaction information is output as one file. The filename is r1 + transaction service starting time (unique 8-digit hexadecimal number).
  This file name is displayed in the message log which indicates that undecided transaction information was output. Delete files which are no longer necessary.
  

Delete unnecessary files containing undecided transaction information following the procedure shown below:

• When deleting a file with a command:
  Execute the trndlinf command.
  
• When deleting information created previously in online mode at OpenTP1 activation:
  Specify the delete condition in the trn_recovery_list_remove and trn_recovery_list_remove_level operands of the transaction service definition.
  

The following items are output as undecided transaction information.

1. OpenTP1 system node ID
   System node ID of OpenTP1
   
2. Global transaction number
   Unique number for managing global transaction set by the system
   
3. Transaction branch number
   Unique number for managing transaction branch set by the system
   
4. Transaction's first status
   Processing status of transaction branch
   
5. Transaction's second status
   Status of transaction branch process
   
6. Transaction's third status
   Communication status of transaction branch
   
7. Process ID
   ID of the process operating the transaction branch
   
8. Server name
   Name of the server which started the transaction branch
   
9. Service name
   Name of the service which started the transaction branch
   
10. Transaction descriptor
    Index number to make distinction between transaction branches having the same transaction global ID
    
11. Branch descriptor
    Index number to make distinction between transaction branches that branched from one transaction branch. For root transaction branch, ********** is displayed.
    
12. Parent transaction descriptor
    Transaction identifier of the transaction which generated the corresponding transaction branch. For root transaction branch, ********** is displayed.
    

Figure A-1 shows the output format of undecided transaction information. Figure A-2 gives an output example.

Figure A-1 Output format of undecided transaction information

Explanation:

(1) Time at which full recovery was started

mmm: Month (lowercase letters)

dd: Day

HH: Hours

MM: Minutes

SS: Seconds

yyyy: Year (d, H, M, S, and y are digits.)

(2) Transaction information

aaaaaaaa:

OpenTP1 system node ID (8 characters)

bbbbbbbb:

Global transaction number (hexadecimal character string)

cccccccc:

Transaction branch number (hexadecimal character string)

dd...dd:

Transaction's first status (20 or less characters)

BEGINNING: Transaction branch start processing is underway.

ACTIVE: Executing

SUSPENDED: Suspended

IDLE: Changing to synchronization point processing

PREPARE: Under commit (phase 1) processing

READY: Waiting for commit (phase 2) processing

HEURISTIC_COMMIT: Heuristic decision commit processing is underway.

HEURISTIC_ROLLBACK: Heuristic decision rollback processing is underway.

COMMIT: Commit processing is underway.

ROLLBACK_ACTIVE: Waiting for rollback processing

ROLLBACK: Rollback processing is underway.

HEURISTIC_FORGETTING: Transaction branch termination processing after heuristic decision is underway.

FORGETTING: Transaction branch termination processing is underway

e:

Transaction's second status (1 character)

u: User server executing a user server process

r: Transaction branch recovery processing in a transaction recovery process

p: Waiting for completion of recovery other transaction branch processing in a transaction recovery process

When the first state is READY and the root transaction branch is not in the same node, direction by the user is awaited.

f:

Transaction's third status (1 character)

s: In sending

r: In receiving

n: Not in sending or receiving

"In sending or receiving" means that the transaction manager is in progress of communication for synchronization between the transaction branches.

gg...gg:

Process ID (decimal number)

hh...hh:

Server name (8 or less characters)

ii...ii:

Service name (32 or less characters) (For SUP, spaces are set.)

jjjjjjjjjj:

Transaction identifier (decimal number)

kkkkkkkkkk:

Branch identifier (decimal number)^#

llllllllll:

Originating transaction identifier (decimal number)^#

#

For root transaction branch, ********** is displayed.
