Operating Systems AIX paging on san Post 302186171 by bakunin on Wednesday 16th of April 2008 02:29:27 PM

Yes - and no.

Paging spaces are used round-robin so they should be all of the same size, this is a thing to observe.

Second, during boot time AIX needs at least one accessible paging space as the system dump is copied there. SAN storage usually is not available during boot, though, so it is a matter of careful planning:

1) Leave at least one paging swapspace on the system disk. Add to that as many swapspaces on SAN devices as you need/want.

2) Make sure that all the swapspaces are of the same size, do NOT create a small swapspace on the system disk and a large ("because there is much more space") swap area on the SAN storage.

For example: If you need 50GB of swapspace and can afford only 5 GB on the system disk then add 9(!) swapspaces of 5GB each on the SAN device instead of one swapspace of 45GB.

I hope this helps.

gnutls_x509_crt_get_subject_alt_name2(3)			      gnutls				  gnutls_x509_crt_get_subject_alt_name2(3)

NAME
gnutls_x509_crt_get_subject_alt_name2 - API function SYNOPSIS
#include <gnutls/x509.h> int gnutls_x509_crt_get_subject_alt_name2(gnutls_x509_crt_t cert, unsigned int seq, void * san, size_t * san_size, unsigned int * san_type, unsigned int * critical); ARGUMENTS
gnutls_x509_crt_t cert should contain a gnutls_x509_crt_t structure unsigned int seq specifies the sequence number of the alt name (0 for the first one, 1 for the second etc.) void * san is the place where the alternative name will be copied to size_t * san_size holds the size of ret. unsigned int * san_type holds the type of the alternative name (one of gnutls_x509_subject_alt_name_t). unsigned int * critical will be non-zero if the extension is marked as critical (may be null) DESCRIPTION
This function will return the alternative names, contained in the given certificate. It is the same as gnutls_x509_crt_get_sub- ject_alt_name() except for the fact that it will return the type of the alternative name in san_type even if the function fails for some reason (i.e. the buffer provided is not enough). RETURNS
the alternative subject name type on success, one of the enumerated gnutls_x509_subject_alt_name_t. It will return GNUTLS_E_SHORT_MEM- ORY_BUFFER if san_size is not large enough to hold the value. In that case san_size will be updated with the required size. If the cer- tificate does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned. REPORTING BUGS
