Is a read only file system supported?

Yes, ActiveServer added support for read only file systems in v1.3.3. To configure a readonly file system, follow the steps below:

  1. Set as.db.password.plain=true or use AWS secrets manager if you would like to encrypt the database credentials.

  2. For keystore setup, use S3, HSM or KMS. If using local SunJCE keystore, there must be a directory that has Read/Write permission for ActiveServer to access. For more information refer to the keystore settings guide.

  3. Disable the file output log by following the disable file output log guide.

  4. There must be a /tmp directory that is Read/Write that is setup for ActiveServer to use. This directory must be mounted as Read/Write, this is required by the web container in which ActiveServer uses.
