OSS Database Files
If a Format 2 file does cause a program to fail, the programmer can do one of the
following:
•
Change the program to accept Format 2 files.
•
Protect the program by converting the file to Format 1 using the following
commands:
FUP CREATE TEMP, FORMAT-1, TYPE U, CODE 180, &
EXT (28,1400), MAXTENTS 749
FUP COPY MYFILE, TEMP
FUP PURGE MYFILE
FUP RENAME TEMP, MYFILE
•
Protect the program by creating a Format 1 file, then appending the desired data to
the file. For example, replace the command:
cp myfile /G/mydisk/mysubvol/myfile
with the commands:
gtacl -c ’FUP CREATE $mydisk.mysubvol.myfile, FORMAT 1, &
TYPE U, ODDUNSTR, CODE 180, EXT (28,1400), MAXTENTS 749’
cat myfile >> /G/mydisk/mysubvol/myfile
OSS Database Files
See the Open System Services Management and Operations Guide and the Open
System Services Installation Guide for information about updating and maintaining
OSS database files. See the Interactive Upgrade Guide 2 for new OSS features and
for a summary of migration or installation issues.
OSS Version 1 Filesets Not Supported
As of the H06.08 RVU, Version 1 filesets are not supported. You must upgrade
Version1 to Version 2 or Version 3 filesets.
The H06.08 RVU adds support for Access Control Lists (ACLs) ifor OSS regular files,
directories, first-in/first-out (FIFO) special files, and bound AF_UNIX sockets in OSS
Version 3 filesets. To use OSS ACLs, you must first migrate to the H06.08 or later
RVU, then migrate your existing filesets to Version 3 filesets. To migrate filesets, you
must stop the OSS filesystem and the OSS environment and use the
fsck DIAGNOSE FILESET, UPGRADE command as described in the Open System
Services Management and Operations Guide.
To restore backup tapes from H06.08 and later RVUs onto H06.05 through H06.07
RVUs, you must install the T0744 Backup/Restore 2 SPR. No T0744 Backup/Restore
2 SPR is available for pre-H06.05 RVUs.
