Processing tables that are currently open z/OS ISPF User's Guide Vol II SC19-3628-00 |
|
Normally, ISPF does not allow a table to be opened and processed
if that table is currently open. However, if the table currently open
has been opened with the SHARE option, a subsequent open of the table
is allowed if:
The ISPF Table Utility provides support which allows you to process a table even when that table is currently open. If a table is currently open in SHARE mode, the ISPF Table Utility can be used to process that table provided you select the "Open table in SHARE mode" option on the ISPF Table Utility panel and the Edit (WRITE) or Browse (NOWRITE) option specified matches the WRITE/NOWRITE setting when the table was originally opened. If a table data set (rather than a table DD) is specified on the entry panel, the ISPF Table Utility also allows you to process a table that is open but not in SHARE mode, or a table that is open in SHARE mode but the WRITE/NOWRITE (edit/browse) setting does not match that of the open table. When this situation is detected, one of the popup windows shown here is displayed allowing you to specify the way in which to process the table: Figure 1. Panel displayed when the
selected table is currently open but not in SHARE mode
The panel shown in Figure 1 is displayed when the selected table from the table data set (TSTTABA) is currently open but not in SHARE mode. Figure 2. Panel displayed when the
selected table is currently open in SHARE mode for NOWRITE
The panel shown in Figure 2 (ISRUTBC1)
is displayed when the selected table (TSTTABA) from the table data
set is currently open in SHARE mode for NOWRITE (not for update) and
you either:
Figure 3. Panel displayed when the
selected table is currently open in SHARE mode for WRITE
The panel shown in Figure 3 (ISRUTBC1)
is displayed when the selected table (ISRPLIST) is currently open
in SHARE mode for WRITE (for update) and you either:
If you press Enter, the table utility:
If you press the Exit key (usually PF3) on panel ISRUTBC1, the
table utility:
If you press Cancel (or Exit on panel ISRUTBC2):
If you edit a temporary copy of an open table, this panel is displayed when you exit the edit display:
This panel allows you to save the updated table in a specified data set and member. The panel initially shows the table data set and table (member) you requested to edit. The "Replace existing member" option allows you to replace an existing member with the data from the table you have edited. If you press Enter, the table utility writes the table data to the specified data set and member. If you press Exit or Cancel, the data from the temporary table is not saved. |
