ZFINT-Schedule Initialization of the File System

Use this command to do any of the following:

Requirements and Restrictions

Format




ON
forces the file system to be initialized during the next cycle up to NORM state if the file system has not been initialized already. If you IPL the system before going to NORM state, you must enter the ZFINT command with the ON parameter again.

BP
forces the file system to be reinitialized during the next cycle up to NORM state.

Attention: Use the BP option with caution to reinitialize the file system. After you initialize the file system you normally should not reinitialize the file system. The BP option will delete any existing files in the file system without cleaning up any system resources that are attached to those files. Other TPF processors should not use the file system while you are reinitializing the file system.

OFF
specifies that you do not want to initialize the file system during the next cycle up to NORM state. The OFF parameter cancels the ZFINT command with the ON parameter.

STATUS
displays the status of the file system initialization indicator.

ADD num
adds to the file system the specified number of #INODE and #FLOCK fixed file records that have already been added to the TPF file address compute program (FACE) table, where num is a positive decimal number from 1-999999.

Use the ADD parameter to increase the number of #INODEand #FLOCK fixed file records in the file system. You must ensure that the FACE tables are compatible on all active TPF images.

Usage
tells how many #INODE and #FLOCK fixed file records are initialized and can be used by the TPF system. This parameter also displays the current cache sizes from the #IZERO fixed file record if the command has been entered on the BSS. The current cache sizes that are displayed may not be the actual cache size if the size has been changed since the last IPL. The actual size of the allocated cache cannot be changed unless one of the following occurs:

DCache dcachenum
allocates the number of entries for the file system directory cache, where dcachenum is a decimal number in the range 0-999 999. If you specify 0, the corresponding cache will not be allocated or, if it is currently active, it will be released. This function is valid only when entered on the BSS.

ICache icachenum
allocates the number of entries for the file system i-node cache, where icachenum is a decimal number in the range 0-999 999. If you specify 0, the corresponding cache will not be allocated or, if it is currently active, it will be released. This function is valid only when entered on the BSS.

Additional Information

Examples

In the following example, the file system will be initialized when the TPF system reaches NORM state.

|System: FINT0001I 06.04.02 FILE SYSTEM INITIALIZATION PENDING                   |
+--------------------------------------------------------------------------------+

In the following example, the file system will not be initialized when the TPF system reaches NORM state.

+--------------------------------------------------------------------------------+
|User:   ZFINT OFF                                                               |
|                                                                                |
|System: FINT0002I 07.14.01 FILE SYSTEM INITIALIZATION NOT PENDING               |
+--------------------------------------------------------------------------------+

The following example requests the status of the file system initialization indicator. The response indicates that the file system will not be initialized when the TPF system reaches NORM state.

+--------------------------------------------------------------------------------+
|User:   ZFINT STATUS                                                            |
|                                                                                |
|System: FINT0002I 08.21.03 FILE SYSTEM INITIALIZATION NOT PENDING               |
+--------------------------------------------------------------------------------+

In the following example, the number of #INODE and #IZERO fixed file records that are initialized is requested.

+--------------------------------------------------------------------------------+
|User:   ZFINT USAGE                                                             |
|                                                                                |
|System: FINT0017I 18.36.46 FILE SYSTEM CACHE SIZE:                              |
|                                DIRECTORY CACHE 1797  INODE CACHE  1347         |
|                                                                                |
|        FINT0011I 18.36.46 490 OF 499 INODE AND 10 OF 10 IZERO RECORDS ARE IN US|
+--------------------------------------------------------------------------------+

In the following example, no #INODE or #IZERO fixed file records are initialized; therefore, the file system is not initialized.

+--------------------------------------------------------------------------------+
|User:   ZFINT USAGE                                                             |
|                                                                                |
|System: FINT0012I 14.14.53 FILE SYSTEM NOT INITIALIZED                          |
+--------------------------------------------------------------------------------+

In the following example, the file system directory cache is created and set to hold 200 000 entries. The #IZERO fixed file record will also be updated with the new value.

+--------------------------------------------------------------------------------+
|User:   ZFINT DCache 200000                                                     |
|                                                                                |
|System: FINT0015I 14.14.53 FILE SYSTEM DIRECTORY CACHE CREATED                  |
