How can I decompress the archive logs with BR*Tools without a restore the database?

Hi experts

Currently the archive logs generated by the DB are compressed with the BR*tools and it have like extension .K. I need to decompress the archive logs with BR*tools. Do this without a restore or recovery of database.

Check the uncompress_cmd on your init<SID>.sap file.

Hi Juan,

Thanks for your response, I checked the link, but the uncompress_cmd parameter is not used when the compress = brtools parameter is set as mentioned in note 1173119. The archives logs currnely have .K as extention, but when I try to uncompress it with the uncompress tool that the initSID.sap have. show the next error. for this reason I need to uncompress the archives logs with brtools, how can do it? or what are the steps to do it with brtools?

Hi Carlos,

Brtools also use operating system compress, so you can use os command to uncompress it.

To confirm whether uncompression works,

alter system dump logfile '<path and name of the file>;

and it will come back with an error if the file is corrupted or wrongly decompressed, or with 'statement completed' if there is no errors detected.

Best regards,
James
