60 Appendix A: Troubleshooting
Archive access issues
Solution • In the Web Console, under database to file parameters, ensure that the
Checksum algorithm parameter is set to MD5 checksum.
• If there truly is a difference between the loaded files and the generated files,
you may need to discard the loaded files and regenerate new archive files in
order to be certain that the files were not corrupted in some way.
Too many files and folders created in HP TRIM
Symptom In HP TRIM, you find that you have many archive data files stored in multiple
folders from just a single run of HP Database Archiving.
Cause When you set the batch size in HP Database Archiving to a smaller number, it
caps the number of rows stored in a file at that level, which can lead to a
proliferation in the number of archive data files. For example, suppose you set the
batch size to 955 for a data set that contains 12,000 rows and HP Database
Archiving generates 14 files.
If, in addition to setting a small batch size, you also set
FolderContentNumber
in
srmsLoader_config.xml to a small number, then you get multiple folders in
HP TRIM. For example, if the
FolderContentNumber is 2, then HP TRIM puts
only 2 files per folder and creates as many folders as it needs to accommodate all
of the files.
Solution • To make fewer but larger archive data files, you can set a larger batch size.
The default batch size is 10,000. A large batch size will reduce the number of
files generated by HP Database Archiving.
• To reduce the number of HP TRIM folders, you can set a higher value for
FolderContentNumber in srmsLoader_config.xml. Zero indicates that
all of the files from a single run will go into one folder, regardless of the
number files.
WARNING! HP TRIM performs better if there are not too many documents inside
a single folder. Approximately 300 documents per folder is the ideal maximum.
When trying to reduce the number of files per folder, you need to consider the
potential impact on performance. If fewer folders might lead to a very large
number of files within a folder, you may want to reconsider your approach.
Archive access issues
This section describes issues that might arise when you are attempting to query
archive files that are stored in HP TRIM.
Cannot search the archive from HP TRIM
Symptom When you try to search the records in HP TRIM, the search fails.
Cause When you extracted the data, if you stored it in .gz format, HP TRIM cannot
search it.
