public class BatchNewtonUpdateForNT

extends Object

implements IDbExtSvc

The BatchNewtonUpdateForNT class implements the IDbExtSvc interface and is executed as part of the Z39.50 Extended Services Database Update request. This class will be responsible for applying the online update to the local Newton database. That entails the batch execution of the Newton database update programs.
Upon the successful completion of the online update, the BER update record will be returned to the application layer via the Z39.50 response task package.

The database updates will use pippin, rome, newtsize, and sortnip programs found in the SSDOT exes directory.

The database ini file setting for Online Update are:

[ExtendedServices]
1.2.840.10003.9.5 = ORG.oclc.util.BatchNewtonUpdateForNT

[ExtendedServicesDbUpdate]
exes = /your directory/dbbuilder/bin
logs = /your directory/dbbuilder/dbs/yourdb/updatelogs
databasepercentfull = 95 (default value)
LockServerName = Lock
journalUpdateDir = /your directory/dbbuilder/dbs/yourdb/journal
recordIdTag = 10/1
recordIdFile = /your directory/dbbuilder/dbs/yourdb/recordid.txt
recordIdClass = ORG.oclc.mantis.util.GetRecordIdFromFile

Possible Database Update Error Conditions:
1. Newton database needs grown - no update submitted.
2. Newton database update failed - check logs for reason.
3. Newton database locked - no update submitted.
4. Unable to communicate with the Lock Server - no update submitted.

The BatchNewtonUpdateForNT class will not submit a record update to the Newton database if any of the database files are greater than the databasepercentfull size specified in the ini file. However, if a database update is submitted and fails, then the administrator will need to analyze the online_update.log file generated. Restart files for pippin and rome will be produced for an update to be restarted manually.
