This may not help you any, but at least it might get some discussion going. Following code exports two schemas, each directly to a compressed disk file. These could then be sent to tape with fbackup.

mknod mypipe p

compress < mypipe > ap.dmp.Z &
exp ap/ap file=mypipe 2> ap.log

compress < mypipe > gl.dmp.Z &
exp gl/gl file=mypipe 2> gl.log

So, are you wanting somehow to send several compressed exported schemas directly to tape, rather than first to disk as above?

NAME
db2ldif - Directory Server script for exporting the database SYNOPSIS
db2ldif [-Z serverID] {-n backend_instance}* | {-s includeSuffix}* [{-x excludeSuffix}*] [-a outputFile] [-m] [-M] [-r] [-u] [-U] [-C] [-N] [-E] [-1] [-q] [-h] DESCRIPTION
Exports the contents of the database to a LDIF file. This script can be executed while the server is still running, except when using the -r option. OPTIONS
A summary of options is included below: -Z Server Identifier The server ID of the Directory Server instance. If there is only one instance on the system, this option can be skipped. -n Backend Name The name of the LDBM database to reindex. Example: userRoot -s includeSuffix Specifies suffixes to be included in the LDIF file. -x excludeSuffix Specifies suffixes to be excluded from the LDIF file. -a Output File The name for the LDIF file. -m Minimize the base64 encodings in the exported LDIF file. -M Exported ldif is stored in multiple files. These files are named : <instance>_<filename> By default, all instances are stored in the filename specified by the -a option. -r Export replication data(information required to initialize a replica when the LDIF is imported). -u Do not export the unique-id attribute. -U Requests that the output LDIF is not folded. -C Uses only the main database file. -N Suppress printing sequential number -E Decrypts any encrypted data during export. -1 Deletes, for reasons of backward compatibility, the first line of the LDIF file that gives the version of the LDIF standard. -q Quiet mode. Suppresses output of the script. -h Display the usage. EXAMPLE
db2ldif -Z instance3 -n userRoot -a /LDAP/ldif/export.ldif db2ldif -s 'dc=example,dc=com' -a /LDAP/ldif/export.ldif -m -E -q DIAGNOSTICS
