********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI47340 :
=================================================

Before applying PTF:
endtcpsvr *FTP

After applying PTF:
strtcpsvr *FTP

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI46704 :
=================================================

1. Before Applying/Removing the ptf:
ENDTCPSVR *FTP

2. Apply the ptf

3. set QIBM_FTP_SRV_TRUNCT_DLY to enable the new feature
ADDENVVAR ENVVAR(QIBM_FTP_SRV_TRUNCT_DLY) LEVEL(*SYS)

4. After Applying/Removing the ptf:
STRTCPSVR *FTP

Adding or removing the value(QIBM_FTP_SRV_TRUNCT_DLY ) while FTP is
running will have an FTP job change behavior on the next incoming
transaction.
FTP will take the change on the next transaction regardless of
the job if the server is restarted using ENDTCPSVR/STRTCPSVR

This new feature will change the "STOR" internal handle behavior
that FTP server will receive the new file to overwrite the existing
file, then it will truncate the receiving file.

Notes: This feature is recommended to enable for certain
scenarios. Example: The existing file is quite big and the size of
the sending file is similar with the existing one. Otherwise,
it is not recommended.

The example to enable the feature:
ENDTCPSVR *FTP
ADDENVVAR ENVVAR(QIBM_FTP_SRV_TRUNCT_DLY) LEVEL(*SYS)
STRTCPSVR *FTP

The example to disable the feature:
ENDTCPSVR *FTP
RMVENVVAR ENVVAR(QIBM_FTP_SRV_TRUNCT_DLY) LEVEL(*SYS)
STRTCPSVR *FTP

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI46345 :
=================================================

2. Apply the ptf

3. set ENV variable to enable the feature
ADDENVVAR ENVVAR(QIBM_FTP_PORT_EPRT_LIMIT) LEVEL(*SYS)

4. After Applying/Removing the ptf:
STRTCPSVR *FTP

Adding or removing the value(QIBM_FTP_PORT_EPRT_LIMIT) while FTP is
running will have an FTP job
change behavior on the next incoming transaction.
FTP will take the change on the next transaction regardless of
the job if the server is restarted using ENDTCPSVR/STRTCPSVR

example to enable the feature:
ENDTCPSVR *FTP
ADDENVVAR ENVVAR(QIBM_FTP_PORT_EPRT_LIMIT) LEVEL(*SYS)
STRTCPSVR *FTP

example to disable the feature:
ENDTCPSVR *FTP
RMVENVVAR ENVVAR(QIBM_FTP_PORT_EPRT_LIMIT) LEVEL(*SYS)

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI40922 :
=================================================

Before Applying/Removing the ptf:
ENDTCPSVR *FTP

After Applying/Removing the ptf:

Note:  This fix relies on message TCP12E2 in message file
