# xmpDB2Util - Frame for DB2 utilities which connect to database
# ------------------------------------------------------------------------------
# Parameter: DML          	- Dateiname der LOAD DML
#            TDB         	- Target Database
#            LOG                - (opt) Log File Name
# Calls ...: xmpSetFunktion.sh	- Funktionsbibliothek
#            xmpSetInstance.sh  - Setzen der xmp DB2 Umgebung
#            db2                - IBM DB2 Command Line Interface
#            xmpLog.pl          - Logging Funktion
# Comment  : Alle, für DB2 Utilities, die DB Connection benötigen (Export, Load
#            etc), erforderlichen Schritte durchführen.
#            - Umgebung aufbauen per xmpSetInstanz.sh
#            - Connect (implizit, ohne Angabe von User und Psw)
#            - Ausführung Utility
#            - Protokollierung auf xmpdba.log
#            - Connect abbauen
# ------------------------------------------------------------------------------
# Autor      GR /03.01.01       - erste Version V1.1
# 27.04.01/GR - V1.2.2: Aufruf von xmpLog.pl war nicht korrekt parameterisiert,
#               Ausgabe der DML im Utility Log und der xmpdba.log Datei,
#               Prüfung auf DB2/SQL Fehler im Utility Log,
#               Formatierung von Fehler- und Warnungen überarbeitet.
# 02.05.01/GR - Korrektur bei echo von "select * ..."
# 08.06.01/GR - V1.2.3: Changed comments and message after applying SetInstanz.sh
# 27.07.01/GR - V1.2.4: Check, wether log file accessible
# 05.11.01/GR - V1.2.5: Write start/stop timestamp into log
# 29.01.02/GR - V1.3: Neew option, TEMPFILES support for DB2 LOAD Utility
# 08.05.02/GR - V1.4: Adapted to Solaris 2.8 (chmod 755 for temporary path),
#                     now considering error message SQL10018N
# 21.08.02/GR - V1.5: Print SQL Messages in case of errors
# 14.05.03/GR - V1.6: Now considering error message SQL3304N
# 04.08.03/GR - V1.7: Now considering error message SQL0911N w/o "error" keyword
# 03.03.04/GR - V1.8: DB2 w/o autocommit, w/o stop at execution error
# 08.03.04/GR - V1.9: Adapt to AIX usage, changed xmpSetInstanz.sh to xmpSetInstance.sh
# 16.05.07/GR - V1.9.1: SQL0091N is not an error message
# 18.05.07/GR - V2.0: Amendment when instance already allocated
