AS-Java (EP-BI-Java) brtools backup vs Export for restoration purpose

[former_member319296]

May seem a novice question but would like to have input on whether an offline Oracle backup of a Java SAP instance is sufficient for safe restoration. We are using SAP Export of the instances currently for the purpose of keeping system backups. Should a complete backup of system not be sufficient instead of taking exports of system.

Does backup of system skips or misses any java configurations ?

Thanks.

Java instances store lots of information on the local filesystem in all kinds of XML and .properties files. Some of the content is also in the database but most of it is not.

That's why a database backup only is not sufficient (as in ABAP instances), you have to take a filesystem backup at the same time you do the database backup to keep the content in sych.

Hi,

while it is usually not possible to schedule offline backups all the time just to get a consistent state between ABAP and J2EE,

it should be sufficiant, do follow this sequence:

- stop sdm

- brspace -c force -u / -f dbalter -a switchlog

- Filesystem backup of /usr/sap/SID/D/j2ee or /usr/sap/SID/J/j2ee trees

- brspace -c force -u / -f dbalter -a switchlog

- start sdm
