corresponds to the transaction that this database manager process started.
-8300 SQL/MP encountered a file-system error. The file-system error and a one-line
description are displayed as part of db-error-buf .
If 0035 is the file-system error:
Cannot obtain an I/O process control block, or the transaction or open lock unit
has been reached. This can occur during the check-in stage of a software input or
when a physical target is being deleted.
The MAXLOCKSPERTCB value might have been exceeded. The default is 5000.
To increase this parameter value, assigned to the disk that contains the database
table in db-error-buf , on a NonStop K-series system:
1. > STOPSCM
2. > TMFCOM; STOP TMF
3. > FUP LISTOPENS $ disk .*.*
4. > PUP LISTDEV $ disk (Note the LDEV and UNIT numbers for later.)
5. > PUP DOWN $ disk
6. > COUP
7. 1) ASSUME DEVICE
8. 2) INFO $ ldev-num , DETAIL

10. 4) SHOW
11. 5) STOP $ ldev-num
12. 6) DELETE $ ldev-num
13. 7) SET UNIT unit-num
14. 8) SET MAXLOCKSPERTCB 6000

On a NonStop S-series system, you do not need to stop TMF or the disk with the
DSM/SCM database. Log on as the super ID and use SCF:
> SCF ALTER DISK $DSMSCM,MAXLOCKSPERTCB 6000
